    ____________________________________)
    Plaintiffs are consumers who contend that defendant retailer represented
    that it properly was charging and in fact charged them sales tax reimbursement on
    sales of hot coffee sold “to go,” when, according to plaintiffs, the tax code
    rendered such sales exempt from sales tax. They brought an action against
    defendant retailer under two consumer protection statutes, seeking a refund of the
    assertedly unlawful charges, damages, and an injunction forbidding collection of
    sales tax reimbursement for such sales. The trial court sustained defendant’s
    demurrer without leave to amend, and the Court of Appeal affirmed, concluding
    that plaintiffs’ action was not authorized under the tax code and was barred by
    article XIII, section 32 of the California Constitution. That provision limits the
    manner in which taxpayers may seek a refund of taxes from the taxing entity.
    We affirm the judgment of the Court of Appeal, although our analysis
    differs somewhat from that court’s analysis. We conclude that the tax code
    provides the exclusive means by which plaintiffs’ dispute over the taxability of a
    retail sale may be resolved and that their current lawsuit is inconsistent with tax
    1
    code procedures. As explained, the consumer protection statutes under which
    plaintiffs brought their action cannot be employed to avoid the limitations and
    procedures set out by the Revenue and Taxation Code.1
    I. FACTS AND PROCEEDINGS BELOW
    A. Proceedings and arguments in the trial court
    Plaintiffs’ first amended complaint alleged that defendant Target
    Corporation (Target)2 had committed an unfair business practice as defined by the
    unfair competition law (UCL) (Bus. & Prof. Code, § 17200 et seq.) and an
    unlawful practice in violation of the Consumer Legal Remedies Act (CLRA) (Civ.
    Code, § 1750 et seq.). The complaint also alleged a cause of action for violation
    of section 6359, a provision exempting many food sales from sales tax. Plaintiffs
    sought class certification.3
    1     Unless otherwise noted, statutory references are to the Revenue and
    Taxation Code (hereafter sometimes referred to as the tax code or the tax law).
    2       Like the Court of Appeal, we refer to defendant in the singular although the
    first and second amended complaints named 100 “Doe” defendants as parties. We
    note that in stating the allegations, plaintiffs’ complaint is inconsistent in its usage.
    3       The first amended complaint also alleged claims for money had and
    received, conversion, and negligent misrepresentation. At the hearing on
    defendant’s demurrer to the first amended complaint, plaintiffs agreed that the
    court should sustain the demurrer without leave to amend as to these three counts,
    and the court did so. Plaintiffs nonetheless appealed from the trial court order
    sustaining the demurrer to the first amended complaint as to these three causes of
    action. In their opening brief in the Court of Appeal, plaintiffs stated that they
    were “not appealing” the trial court’s ruling with respect to the conversion and
    negligent misrepresentation causes of action. The Court of Appeal concluded the
    trial court correctly sustained the demurrer to the money had and received claim.
    Plaintiffs did not specifically challenge this conclusion in their petition for review
    and it is not discussed in this opinion.
    2
    Plaintiffs alleged that “the sale of hot coffee drinks ‘to go’ or for ‘take-out’
    is not subject to sales tax” under section 6359 and a related regulation adopted by
    the state Board of Equalization (Board). They alleged that defendant nonetheless
    charged what the complaint referred to as “sales tax” on purchases of hot coffee to
    go to two named plaintiffs, and “thus caused [plaintiffs] to suffer monetary loss.”
    (As we shall see, the complaint is inaccurate to the extent it refers to plaintiffs’
    payment to the retailer as “sales tax.” The tax code provides that the retailer is the
    taxpayer and that it is the retailer which is required to pay sales tax to the state; the
    retailer is permitted but not required to collect a matching “sales tax
    reimbursement” from consumers. It is the reimbursement charge that is at issue in
    the present case.)
    Plaintiffs also alleged that “[defendant] falsely and illegally represented to
    members of the general public that it had the legal right to charge the sales taxes
    described herein including, but not limited to, oral representations made by [its]
    agents, and on receipts and registers at [its] facilities.”
    Plaintiffs alleged that defendant’s actions constituted “unlawful, unfair and
    fraudulent business acts and practices within the meaning of . . . Business and
    Professions Code section 17200, et seq.” It was further alleged that “[b]y [its]
    actions, [defendant] unfairly and unlawfully increased the costs to Class members
    in direct contradiction to law. In the event [defendant] retained these monies it
    unjustly enriched itself at the expense of Plaintiffs, other Class members and the
    general public and, as such, [defendant’s] conduct amounts to unfair competition”
    and “offends public policy and is immoral, unscrupulous, unethical and offensive,
    and causes substantial injury.” The complaint alleged continuing violations and
    asserted that defendant “refused to publicly acknowledge [its] improper imposition
    of the charges, correct [its] wrongdoing, and provide compensation . . . .”
    3
    Plaintiffs sought an order enjoining defendant from “improperly charging
    sales tax to consumers” on hot coffee to go, and from withholding information
    regarding its practices. Plaintiffs also sought “restitution of any monies
    wrongfully acquired or retained” and “disgorgement of . . . ill-gotten gains
    obtained by means of . . . unfair practices.”
    Plaintiffs alleged a violation of the CLRA in that defendant
    “(a) misrepresented the source, sponsorship, approval or certification of [its]
    charges for sales taxes by indicating to consumers that [it has] . . . the legal
    authority to charge the sales taxes that [it has] . . . charged and continue[s] to
    charge”; (b) “[misrepresented the] affiliation, connection, or association with, or
    certification by, another by indicating to consumers that [it has] . . . the legal
    authority to charge the sales taxes . . . ; [misrepresented that] the transactions at
    issue confer or involve rights, remedies, or obligations which [it does] not have or
    involve, or which are prohibited by law by charging the sales tax”; and inserted an
    unconscionable provision into contracts by charging the assertedly improper “sales
    tax.”
    Plaintiffs alleged that they had informed defendant by mail of its alleged
    violation of the CLRA and made a “demand for remedy,” but that no remedy has
    been forthcoming.
    Plaintiffs sought an order “enjoining the [defendant] from continuing the
    methods, acts and practices set out above regarding [its] charging of illegal sales
    taxes . . . .” They sought damages in “the amount of sales taxes wrongfully
    collected from plaintiffs and the Class for the purchase of hot coffee ‘to go’ or for
    ‘take out,’ without being limited thereto” and punitive damages on the ground that
    “[defendant’s] conduct allegedly was willful, oppressive and fraudulent.”
    Finally, plaintiffs sought an order certifying the class, awarding restitution
    and disgorgement, enjoining the continuation of “illegal practices,” requiring
    4
    defendant to “inform the public of [its] unlawful practices and enjoining
    [defendant] from the practices complained of.”
    Defendant demurred. It objected that plaintiffs’ action would call upon the
    court to order a refund and enjoin collection of the sales tax reimbursement “on
    the allegedly non-taxable items” “without a determination that Target erroneously
    paid the tax to the [Board].” Defendant argued that article XIII, section 32 of the
    state Constitution barred such a proceeding because plaintiffs’ lawsuit sought, in
    effect, “an order preventing the [Board] from collecting this tax” and “remedies
    not provided for” in the tax code.
    Defendant also argued that consumer remedies regarding sales taxes should
    be permitted only as specifically provided by the Legislature, asserting that the
    Board is responsible in the first instance for deciding whether retailers have
    collected too much sales tax reimbursement from consumers.
    In addition, defendant argued that the court should decline to exercise
    jurisdiction over plaintiffs’ claims, but should defer to the Board under the
    doctrine of primary jurisdiction.
    Plaintiffs responded that at the demurrer stage, there was no record of
    whether Target paid the sales tax it collected to the Board, nor need there be any
    such allegation in the complaint. Plaintiffs argued that the Legislature had
    specifically provided that they “may sue Target for illegally charging them sales
    tax,” alluding in support to section 6901.5 and a decision of this court interpreting
    a predecessor to that statute, Javor v. State Board of Equalization (1974) 
    12 Cal. 3d 790
    (Javor). Section 6901.5, they asserted, afforded them a private right of action
    “against those who charge them improper sales taxes.”
    Plaintiffs further asserted that the state constitutional limitation on lawsuits
    for tax refunds (Cal. Const., art. XIII, § 32) did not apply, and that the doctrine of
    primary jurisdiction should not apply.
    5
    As for their UCL claim, plaintiffs argued that even if the tax code provided
    no private right of action, the UCL supplied a basis for their claim. They alleged
    that violation of section 6359 (exempting many food sales from sales tax), and the
    statute’s related regulation, is “unlawful” and therefore supports their UCL claim.
    At the hearing on the demurrer, the trial court observed that “a
    determination has to be made by the [Board] regarding [any] . . . ‘refund’ . . . or
    ‘damages’. . . pursuant to sections 6901 [governing refunds from the Board to
    retailers] and 6901.5 [governing the return of excess reimbursement from
    consumers].” It added: “If the [Board] makes a determination, then the case or
    these causes of action might be ripe for adjudication.”
    In response, plaintiffs requested leave to amend the complaint to “bring in
    the Board and then proceed in that manner.” There was some discussion of an
    amendment that would constitute a suit to compel defendant to seek a refund from
    the Board, but the court warned, “I’m not going to be creative for you. I’m going
    to allow you to try to amend the first three causes of action to see what we get out
    of it.” The court sustained the demurrer with leave to amend as to the three causes
    of action discussed above, formally granted plaintiffs’ motion for leave to add the
    Board as a defendant, and sustained the demurrer without leave to amend as to the
    money had and received, conversion, and negligent misrepresentation causes of
    action.
    Plaintiffs filed a second amended complaint, but this complaint did not add
    the Board as a defendant. Their amended complaint simply added a few details
    concerning plaintiffs’ purchases, and alleged that defendant Target never inquired
    whether the named plaintiffs’ coffee purchases were to go, thereby depriving
    plaintiffs of the “opportunity to avoid being wrongfully charged the taxes at
    issue.”
    6
    Defendant once more demurred, repeating that the remedies plaintiffs
    sought were unavailable under the state Constitution because the injunctive
    remedy essentially would prevent the Board from collecting the tax, and a
    restitution award would afford tax relief in a manner not established by the
    Legislature. Defendant maintained that section 6901.5, a provision that governs
    reimbursement refunds, does not create a private right of action for consumers, but
    instead contemplates that consumers should apply to the Board to, in the words of
    the statute, “ascertain[]” whether retailers should make any refund to consumers.
    Defendant also repeated its assertion that the court should decline to exercise its
    equitable power under the doctrine of primary jurisdiction.
    At the hearing on the demurrer, the trial court commented that the second
    amended complaint was “déjà vu all over again.” The court explained that the
    question whether plaintiffs were appropriate “complainants” had not been
    answered and stated that “[n]either the statutory [scheme] nor any case authority
    allows you to go forward with this type of action unless there’s been, at the very
    least — and I don’t have an opinion about this — some request to the tax
    court . . . .”
    Plaintiffs responded first that “regardless of whether the . . . [Board] should
    be involved, the representation by [defendant] to its customers that they are paying
    a sales tax when in fact, they are not is an unfair business practice.” Second,
    plaintiffs disputed the significance of the question of the Board’s “jurisdiction
    over this claim.” Plaintiffs asserted that the court had assumed that defendant had
    paid the Board sales tax on sales of hot coffee, but “the complaint doesn’t allege
    that” and it is wrong for the “court [to] make that assumption.” Third, counsel for
    plaintiffs stated that “what some courts have done in this circumstance that I’ve
    been involved with is that they stay the case, advise us to go seek the refund from
    7
    the [Board], and inevitably when that answer is ‘no,’ we can come back and then
    we are allowed to go forward with our case.”
    Defendant countered that plaintiffs had chosen the wrong way to go about
    their claim, and objected to the idea of staying the case, permitting plaintiffs to
    seek reimbursement from the Board, then returning to court. On the contrary,
    defendant argued, plaintiffs may do no more than was authorized in our Javor
    decision (see 
    Javor, supra
    , 
    12 Cal. 3d 790
    ), in which we permitted consumers to
    bring an action to require retailers to seek a sales tax refund from the Board.
    Defendant emphasized that plaintiffs had exhibited no interest in taking such a
    course.
    The court sustained the demurrer to the second amended complaint without
    leave to amend and dismissed the case with prejudice, stating that it agreed with
    “much” of defendant’s argument and written pleadings.
    B. Arguments on appeal, and the Court of Appeal’s decision
    Plaintiffs appealed, contending primarily that section 6901.5 afforded them
    a private right of action against defendant. Despite their concession at the hearing
    on the first amended complaint that the demurrer should be sustained without
    leave to amend as to the cause of action for money had and received, they also
    contended they had adequately pleaded that cause of action.
    In response, defendant contended that the suit was barred by the California
    Constitution, and that section 6901.5 does not provide for a private right of action.
    It also disputed plaintiffs’ claim concerning the money had and received count.
    In reply, plaintiffs denied that article XIII, section 32 of the state
    Constitution applied to their suit, insisted that the language of section 6901.5
    authorized their lawsuit, and argued that even if a Board determination was a
    prerequisite to their suit, the trial court should have stayed the action under the
    doctrine of primary jurisdiction.
    8
    The Court of Appeal affirmed the judgment in favor of defendant. It
    rejected plaintiffs’ claim that the tax code itself afforded them a private right of
    action against retailers, and concluded that their UCL and CLRA claims were
    inconsistent with article XIII, section 32 of the state Constitution.
    The Court of Appeal pointed to the tax code’s comprehensive sales tax
    scheme and its intertwining provisions governing retailers. It emphasized that it is
    retailers who pay sales tax to the state, and that under the tax code, it is retailers
    who may file a claim with the Board seeking a refund of overpaid sales tax.
    Customers, the court pointed out, lack standing to file a claim with the Board for a
    tax refund. The Court of Appeal rejected plaintiffs’ reliance upon section 6901.5
    as a basis for a private right of action against the retailer. It declared that the
    statute makes some provision for the refund of excess tax reimbursement amounts
    to consumers, but the statute and related regulation do not provide a private right
    of action for consumers. On the contrary, the reviewing court declared that
    nothing in section 6901.5 “affirmatively indicates the intent of the Legislature to
    authorize a private action by a customer against a retailer. . . . Rather, the statute
    relates to a claim with the Board”— not a lawsuit — and the statute and related
    regulation direct a retailer to make a refund to customers if the Board has
    “ ‘ascertained’ ” that one is due.
    The Court of Appeal believed that the Legislature has vested in the Board
    the authority to enforce the sales tax law, and that it would undermine the statutory
    scheme to permit customers to unilaterally “ ‘ascertain’ ” when excess sales tax
    reimbursement had been collected. The court stated that plaintiffs’ contrary claim
    “would disrupt the administration of the sales tax laws because it would allow
    customers to usurp the authority of the Board to determine the application of the
    law in the first instance.” The reviewing court pointed out that the Board has not
    had an opportunity to ascertain whether sales tax was due on defendant’s sale of
    9
    hot coffee to go, nor has it ascertained whether any reimbursement is due under
    section 6901.5.
    Moreover, according to the Court of Appeal, plaintiffs are trying to use the
    UCL and CLRA to resolve a sales tax dispute, but “[t]his they cannot do under
    article XIII, section 32” of the state Constitution. In the appellate court’s view,
    constitutional restrictions would not permit a consumer action seeking to declare a
    particular sale exempt from tax, because a resulting award in favor of consumers
    could afford a tax refund in a manner not specifically authorized by the
    Legislature. The court also believed that constitutional principles would not
    permit an injunction against defendant’s collection of sales tax reimbursement,
    because such an injunction could curtail tax collections.
    The Court of Appeal summarized its constitutional analysis and holding as
    follows: “Article XIII, section 32 prohibits injunctions against the collection of
    state taxes and provides that refunds of taxes may only be recovered in a manner
    provided by the Legislature. As our Supreme Court explained in Woosley v. State
    of California (1992) 
    3 Cal. 4th 758
    , 792 (Woosley), under article XIII, section 32,
    the courts cannot expand the methods for seeking tax refunds expressly provided
    by the Legislature. The purpose of this constitutional provision is to ensure that
    governmental entities may engage in fiscal planning so that essential public
    services are not unnecessarily interrupted. [¶] . . . [¶]
    “The complaint also alleges causes of action under unfair business practices
    and consumer protection statutes and a cause of action for money had and
    received. Plaintiffs seek damages, restitution and injunctive relief pursuant to
    these causes of action. However, plaintiffs are attempting to resolve a sales tax
    dispute by using consumer and common law remedies rather than the procedure
    set forth by the Legislature. This they cannot do under article XIII, section 32.
    10
    “Plaintiffs argue that they are not violating article XIII, section 32, because
    they do not seek to enjoin the state from collecting sales taxes. Rather, plaintiffs
    contend, they seek to enjoin a private company from collecting sales tax
    reimbursement. Plaintiffs further contend that article XIII, section 32 is not
    implicated because they only seek a refund of sales tax reimbursement, not a
    refund of sales taxes.
    “We reject plaintiffs’ argument and find that a court may not directly or
    indirectly enjoin or prevent the collection of a sales tax. As we will explain, the
    statutory schemes for sales taxes and sales tax reimbursement are intertwined. A
    determination by a court that sales tax is not due on ‘to go’ hot coffee purchases
    from Target, and an injunction against the collection of sales tax reimbursement
    by Target on such purchases, is effectively an injunction against the collection of
    sales tax by the state. Further, under article XIII, section 32, plaintiffs cannot
    circumvent the statutory scheme for sales tax reimbursement refunds by asserting
    causes of action not contemplated by that scheme. We therefore affirm the
    judgment and hold that plaintiffs’ action is barred by article XIII, section 32 and
    the sales tax statutes in the Revenue and Taxation Code.”
    C. Parties’ claims
    We granted plaintiffs’ petition for review. Plaintiffs challenge the Court of
    Appeal’s constitutional analysis, and contend that UCL and CLRA remedies are
    cumulative to any remedy or procedure that is available under the tax code.
    Plaintiffs have now stated that they do not challenge that part of the Court of
    Appeal’s decision rejecting their own claim in that court that the tax code, and
    specifically section 6901.5, provided them with a private right of action against
    defendant. On the contrary, in this court plaintiffs argue that the absence of a
    private right of action for consumers under the tax code makes it imperative that
    this court recognize their remedies under the UCL and CLRA. They contend, too,
    11
    that the Court of Appeal’s decision would undermine UCL and CLRA actions in
    general and would leave consumers who are charged unauthorized or excessive
    sales tax without a remedy.
    Defendant contends that the Court of Appeal correctly analyzed the
    constitutional and statutory provisions and properly concluded that plaintiffs’
    action is barred.
    II. DISCUSSION
    On appeal, “[w]hen a demurrer [has been] sustained, we determine whether
    the complaint states facts sufficient to constitute a cause of action. [Citation.]
    And when it is sustained without leave to amend, we decide whether there is a
    reasonable possibility that the defect can be cured by amendment: if it can be, the
    trial court has abused its discretion and we reverse.” (City of Dinuba v. County of
    Tulare (2007) 
    41 Cal. 4th 859
    , 865; see Code Civ. Proc., § 430.10, subd. (e).) We
    follow the well-settled rule that “[w]hen reviewing a judgment dismissing a
    complaint after the granting of a demurrer without leave to amend, courts must
    assume the truth of the complaint’s properly pleaded or implied factual
    allegations.” (Schifando v. City of Los Angeles (2003) 
    31 Cal. 4th 1074
    , 1081.)
    On the other hand, the reviewing court “does not . . . assume the truth of
    contentions, deductions or conclusions of law.” (Aubry v. Tri-City Hospital Dist.
    (1992) 
    2 Cal. 4th 962
    , 967.)
    We summarize our conclusions, which depend upon a proper understanding
    of both the procedural and substantive aspects of the governing sales tax
    provisions. The clear basis of plaintiffs’ action — that Target represented that it
    properly was charging and in fact charged sales tax reimbursement on a sale that
    plaintiffs believe the tax code exempted from taxation — requires resolution of a
    sales tax law question, that is, whether Target’s sales of hot coffee to go to
    plaintiffs were subject to sales tax or fell within an exemption. That question,
    12
    which we may characterize as the “taxability” question, is committed in the first
    instance to the Board, subject to judicial review under the restrictions and pursuant
    to the procedures provided by the tax code. A UCL or CLRA cause of action such
    as plaintiffs’ cannot be reconciled with the primary decisionmaking role that the
    tax code vests in the Board with respect to tax issues. Moreover, section 6901.5
    provides a safe harbor for a retailer/taxpayer who remits reimbursement charges to
    the Board. For these reasons, the tax code precludes claims such as plaintiffs’.
    Although in the past we have permitted consumer intervention into the
    sales tax scheme in limited circumstances and only by means of a judicial
    proceeding to compel the retailer/taxpayer to seek a refund from the Board (see
    
    Javor, supra
    , 
    12 Cal. 3d 790
    ), such a remedy invokes, rather than avoids, tax code
    procedures. Plaintiffs in the present case did not pursue that remedy.
    Because we can resolve the issues presented on statutory grounds, it is not
    necessary to resolve the constitutional question addressed by the Court of Appeal,
    although constitutional considerations enter into our interpretation of the relevant
    statutes.4
    A. Article XIII, section 32 of the state Constitution
    The Court of Appeal’s determination that plaintiffs’ claims were barred
    rested in large part upon article XIII, section 32 of the state Constitution: “No
    legal or equitable process shall issue in any proceeding in any court against this
    State or any officer thereof to prevent or enjoin the collection of any tax. After
    4      We express no view on a question not presented by the complaint in this
    case, namely, whether or to what extent consumers may bring a UCL or CLRA
    claim against retailers for failing to remit to the Board amounts the retailer has
    represented and collected as sales tax reimbursement charges. In their
    supplemental briefs, plaintiffs have acknowledged that their lawsuit does not rest
    on such a claim.
    13
    payment of a tax claimed to be illegal, an action may be maintained to recover the
    tax paid, with interest, in such manner as may be provided by the Legislature.”
    (All further article references are to the California Constitution.)
    We have explained that the policy behind the provision is to ensure that the
    State may continue to collect tax revenue during litigation in order to avoid
    unnecessary disruption of public services that are dependent on that revenue.
    (Pacific Gas & Electric Co. v. State Bd. of Equalization (1980) 
    27 Cal. 3d 277
    (Pacific Gas & Electric Co.).) We have observed that delay in tax collection
    “ ‘may derange the operations of government, and thereby cause serious detriment
    to the public.’ ” (Id. at p. 283.) To serve the same end, the constitutional
    provision not only bars prepayment actions by taxpayers seeking injunctive relief
    but ordinarily also bars those seeking declaratory relief or mandamus. (Id. at
    pp. 280-281; Calfarm Ins. Co. v. Deukmejian (1989) 
    48 Cal. 3d 805
    , 838; State Bd.
    of Equalization v. Superior Court (1985) 
    39 Cal. 3d 633
    , 638-639 [“[T]he sole
    legal avenue for resolving tax disputes is a postpayment refund action. A taxpayer
    may not go into court and obtain adjudication of the validity of a tax which is due
    but not yet paid”; the constitutional provision prohibits “not only injunctions but
    also a variety of prepayment judicial declarations or findings which would impede
    the prompt collection of a tax”].) In sum, “[t]he section applies if the prepayment
    judicial determination sought would impede tax collection.” (Western Oil & Gas
    Assn. v. State Bd. of Equalization (1987) 
    44 Cal. 3d 208
    , 213 (Western Oil & Gas
    Assn.).)
    Article XIII, section 32 also requires that tax refund actions be brought
    solely according to procedures established by the Legislature. It vests power over
    tax procedure in the Legislature, and limits or governs the authority of the courts
    over tax collection disputes. (Western Oil & Gas 
    Assn., supra
    , 44 Cal.3d at p. 213
    [the provision “broadly limits in the first instance the power of the courts to
    14
    intervene in tax collection matters”].) This deference also serves the state’s
    interest in being able to plan for needed public expenditures, and “rests on the
    premise that strict legislative control over the manner in which tax refunds may be
    sought is necessary so that governmental entities may engage in fiscal planning
    based on expected tax revenues.” 
    (Woosley, supra
    , 3 Cal.4th at p. 789; see Pacific
    Gas & Electric 
    Co., supra
    , 27 Cal.3d at p. 283.)
    Plaintiffs argue that article XIII, section 32 does not apply to or bar their
    lawsuit because the provision applies solely (1) to actions against the state or its
    officers; and (2) to lawsuits brought by taxpayers; (3) to recover the tax paid.
    Plaintiffs observe that their action for restitution, damages, and injunctive relief is
    not against the state, or indeed any government taxing entity. They add that the
    reimbursement amount they challenge is not a tax, but an amount they, as
    nontaxpayers, paid to retailers pursuant to a contractual arrangement. They claim,
    moreover, that their action will not impair the state’s ability to collect taxes, nor
    will the action recognize a refund procedure that is inconsistent with the tax code.
    In response, defendant maintains that under the state Constitution, tax
    refund issues may be litigated solely according to the procedure specifically
    provided by the tax code, and that plaintiffs’ lawsuit is inconsistent with that
    scheme. Defendant observes that the constitutional provision prohibits lawsuits to
    prevent or enjoin the collection of any tax, and argues that “because an action to
    recover sales tax reimbursement is substantively indistinguishable from an action
    to recover the tax paid, this constitutional protection must be afforded to retailers
    collecting sales tax reimbursement from their customers.”
    Our jurisprudence directs that we avoid resolving constitutional questions if
    the issue may be resolved on narrower grounds (Santa Clara County Local
    Transportation Authority v. Guardino (1995) 
    11 Cal. 4th 220
    , 230), and that we
    adopt an interpretation of the relevant statutes that gives full effect to their
    15
    language and purpose, but also “eliminates doubts as to the statute’s
    constitutionality.” (Harrott v. County of Kings (2001) 
    25 Cal. 4th 1138
    , 1151; see
    Conservatorship of Wendland (2001) 
    26 Cal. 4th 519
    , 548.)
    As already noted, and applying this authority, our interpretation of the tax
    code renders it unnecessary to resolve the constitutional question addressed by the
    Court of Appeal, although constitutional considerations enter into our
    interpretation of the relevant statutes.
    B. Overview of relevant provisions of the tax law
    As noted previously and as discussed more fully hereafter, under
    California’s sales tax law, the taxpayer is the retailer, not the consumer. In
    addition, the taxability question, whether a particular sale is subject to or is exempt
    from sales tax, is exceedingly closely regulated, complex, and highly technical. A
    comprehensive administrative scheme is provided to resolve these and other tax
    questions and to govern disputes between the taxpayer and the Board. Under these
    administrative procedures, it is for the Board in the first instance to interpret and
    administer an intensely detailed and fact-specific sales tax system governing an
    enormous universe of transactions. Administrative procedures must be exhausted
    before the taxpayer may resort to court. Parts II.B.1. and II.B.2. below describe
    the system in more detail, supporting the view that this comprehensive statutory
    scheme is inconsistent with consumer claims such as plaintiffs’ by which a party
    other than the taxpayer would seek to litigate whether a sale is taxable or exempt.
    As for the interests of consumers, parts II.B.3. and II.B.4. describe the
    position historically accorded to them by statute and case law, and also set out the
    current statutory system governing consumer reimbursements. More specifically,
    retailer/taxpayers are permitted, but not required, to contract with consumers to
    charge a reimbursement amount to reimburse the retailer for its own payment of
    sales tax on a transaction. Alternatively, the retailer may choose simply to absorb
    16
    the sales tax. Retailer/taxpayers cannot retain the reimbursement amounts they
    receive from consumers. When it is “ascertained” (§ 6901.5), whether through a
    Board audit or deficiency determination or a refund proceeding, that a retailer
    miscalculated its sales tax and charged consumers an erroneous reimbursement
    amount, the retailer has a choice whether to make a refund to consumers or
    instead, to remit the amount to the Board. Significantly, a retailer who remits the
    amount to the Board reaches a “safe harbor.” In addition, there is no formal
    administrative procedure for consumers who believe they have been charged
    excess reimbursement, although they may complain to the Board, which may in
    turn initiate an audit. Finally, we have recognized that in certain circumstances a
    consumer may bring an action to require a taxpayer to seek a refund from the
    Board, a proceeding in which the Board would ascertain whether excess
    reimbursement had been charged and, assuming any excess had been remitted by
    the taxpayer to the state, issue a refund to the taxpayer conditioned on its, in turn,
    making a refund to the consumer.
    As we shall explain, it would be inconsistent with this scheme to permit the
    consumer to initiate a consumer action such as plaintiffs’ requiring a court to
    resolve, outside the searching regulatory scheme established by the tax code,
    whether a sale was taxable or exempt, and for the court to interfere in the statutory
    system by which the retailer is authorized to satisfy its obligations by remitting
    excess tax reimbursement amounts to the Board.
    1. Who is the taxpayer and what sales are taxable?
    The sales tax is imposed on retailers “[f]or the privilege of selling tangible
    personal property at retail.” (§ 6051.) The retailer is the taxpayer, not the
    17
    consumer.5 “The tax relationship is between the retailer only and the state; and is
    a direct obligation of the former.” (Livingston Rock & Gravel Co. v. De Salvo
    (1955) 
    136 Cal. App. 2d 156
    , 160; see also 9 Witkin, Summary of Cal. Law (10th
    ed. 2005) Taxation, § 344, p. 497; 56 Cal.Jur.3d (2011) Sales and Use Taxes, § 10,
    p. 22.)
    The sales tax law provides the method by which retailers are required to
    calculate taxable sales and remit the tax to the Board. Retailers must file returns
    and pay sales tax quarterly on their gross sales for the preceding quarter.
    (§§ 6451-6459.) For high volume sellers, the tax or a portion thereof must be
    prepaid on a quarterly basis using a portion of prior year sales tax liability as a
    measure. (§§ 6471-6479; 9 Witkin, Summary of Cal. 
    Law, supra
    , Taxation,
    § 369, p. 541.)
    The central principle of the sales tax is that retail sellers are subject to a tax
    on their “gross receipts” derived from retail “sale” of tangible personal property.
    (§ 6051.)
    Despite the apparent simplicity of a tax based on gross receipts, a complex
    system of statutes and regulations minutely controls tax liability. This system
    closely defines taxable sales,6 governs whether particular sales or transactions are
    subject to the tax, and defines what constitutes “gross receipts.”7
    5      By contrast, the use tax falls on the purchaser, although the retailer may
    collect the tax as an agent. (§§ 6202, 6203; Bank of America v. State Bd. of Equal.
    (1962) 
    209 Cal. App. 2d 780
    , 799; see also Direct Marketing Ass’n, Inc. v. Bennett
    (9th Cir. 1990) 
    916 F.2d 1451
    , 1454-1455.)
    6       The term “sale” means “[a]ny transfer of title or possession, exchange, or
    barter, conditional or otherwise, in any manner or by any means whatsoever, of
    tangible personal property for a consideration.” (§ 6006, subd. (a).) The term is
    defined as including many specific transactions, including “[t]he furnishing,
    (footnote continued on next page)
    18
    Of particular note given plaintiffs’ argument that consumer claims should
    lie when the retailer fails to correctly apply sales tax exemption law, an entire
    chapter of the sales and use tax law is devoted to exemptions. (§ 6351 et seq.)
    The law of exemptions is comprehensive, governing every imaginable type of
    (footnote continued from previous page)
    preparing, or serving for a consideration of food, meals, or drinks.” (§ 6006,
    subd. (d).)
    An example illustrates the statutory refinements to the term “sale” that face
    the taxpayer and the Board. Leases of tangible personal property for a
    consideration are included as sales, with some readily understood exceptions, such
    as leases of motion pictures or household furnishings leased along with living
    quarters (§ 6006, subd. (g)(1), (3)), and a host of other exceptions for a number of
    closely defined circumstances. These include “[t]angible personal property leased
    in substantially the same form as acquired by the lessor or leased in substantially
    the same form as acquired by a transferor, as to which the lessor or transferor has
    paid sales tax reimbursement or has paid use tax measured by the purchase price
    of the property,” with the term “transferor” including “[a] person from whom the
    lessor acquired the property in a transaction described [by another statute as an
    occasional sale],” or “ [a] decedent from whom the lessor acquired the property by
    will or the laws of succession.” (§ 6006, subd. (g)(5); see Preston v. State Bd. of
    Equalization (2001) 
    25 Cal. 4th 197
    (Preston) [considering whether a certain
    agreement to provide artwork constituted a taxable sale or lease of tangible
    personal property or an exempt transfer of an intangible copyright interest].)
    7        “Gross receipts” are defined in pertinent part as “the total amount of the
    sale . . . price . . . of the retail sales of retailers, valued in money, whether received
    in money or otherwise,” generally without deduction for the cost of the property,
    or the cost of materials, labor, transportation, or certain federal taxes. (§ 6012,
    subd. (a).)
    Again, to illustrate the complexity facing the taxpayer and the Board, the
    crucial term “gross receipts” is subject to detailed refinement, and the limitation
    on deductions or exclusions from gross receipts is subject to a number of
    exceptions, from readily understood circumstances such as cash discounts given
    on sales, or the amount refunded to customers for items returned by the customer
    (see § 6012, subd. (c)(1), (2)), to a number of other circumstances subject to
    detailed conditions defined in terms of the “reasonableness” of the charge. (See
    § 6012, subd. (c)(10)(A); see also 
    id., subd. (c)(7).)
    The term “sales price”
    contains parallel complications. (See § 6011.)
    19
    sales transactions. One article in the exemption chapter includes 79 provisions
    exempting particular types of transactions from sales and use taxation —
    including, for example, relatively straightforward exemptions for poultry litter
    (§ 6358.2), to much more complicated and fact-specific exemptions for some sales
    of food or medicine (§§ 6359, 6369) or for gross receipts from food stamp sales
    (§ 6373), to some quite arcane exemptions. (See § 6366.5 [sales of endangered
    species].) Many exemptions apply to various types of charitable or nonprofit
    transactions. (See § 6360.1 [sales of veteran’s memorial lapel pins]; see also
    §§ 6359.3, 6361, 6361.5, 6363.2-6363.8.) Some of the exemptions turn on the use
    to which the purchaser will put the item being sold or leased (see §§ 6366.4
    [artwork sold to nonprofit museums for the purpose of public display], 6368.1
    [leasing of watercraft for specified purposes]), and in some instances, the law
    exempts transactions from only a small portion of the sales tax. (See § 6376.1.)
    In this case, plaintiffs assert that the sales tax law plainly exempts the sale
    of hot coffee to go from sales tax, and that Target violated the UCL and CLRA by
    collecting reimbursement on an assertedly nontaxable sale. Plaintiffs refer to
    section 6359, which generally exempts the “sale of . . . use, or other consumption”
    of food products. (§ 6359, subd. (a).)
    There are many exceptions to the exemption appearing in section 6359,
    however. Food products are not exempt if they are “served as meals on or off the
    premises.” (Id., subd. (d)(1).) Also not qualifying for the exemption are items
    that are “furnished, prepared, or served for consumption at tables, chairs, or
    counters or from trays, glasses, dishes, or other tableware” provided by the
    retailer. (Id., subd. (d)(2).) In other words, a distinction is drawn between items
    of food depending on whether they are consumed on the premises. The exemption
    also does not apply when “foods products are sold as hot prepared food products.”
    (Id., subd. (d)(7).) On the other hand, the “ ‘hot prepared food products’ ”
    20
    exception to the exemption does not apply “to a sale for a separate price of bakery
    goods or beverages (other than bouillon, consommé, or soup)” under defined
    conditions. (Id., subd. (e).)
    Accompanying regulations descend to the finest details. (See Cal. Code
    Regs., tit. 18, § 1602 et seq.) The regulation defining the taxability of food
    products is of amazing complexity. (Id., § 1603.) The regulation applies the tax
    to sales of hot prepared foods (a term subject to very extensive refinement and
    somewhat contradictory definition (see 
    id., § 1603,
    subd. (e)), with provisions for
    items furnished by specified establishments “whether served on or off the
    premises.” (Id., § 1603, subd. (a)(2)(A).) There are special rules for sales of
    straws and toothpicks along with food (ibid.), and a definition of “hot prepared
    food products” that distinguishes between items sold separately and those sold
    under a single price along with cold foods (id., subd. (e)(1)), which appears to
    exempt hot coffee if sold separately but not if sold with a bakery item, unless
    taxable because, among other reasons, it was sold for consumption at tables,
    chairs, or counters provided by the retailer. (Id., § 1603, subds. (e), (f).)
    In an amicus curiae brief filed in this court, the Board explains that “to go”
    sales are those for which the customer leaves the store’s premises entirely before
    consuming the item. “Target would have to distinguish sales of coffee where the
    customer bought the coffee and immediately left the store from those where the
    customer bought the coffee but continued to shop in the same store or drank the
    coffee at tables and chairs in the coffee sales area. In addition, since the analysis
    must be made on a location-by-location basis, Target would need to conduct
    investigations in each of its California locations. [Citation.] The amount of
    administrative expense incurred to obtain such figures and maintain proper records
    would likely be passed on to Target’s customers in the form of higher prices.”
    21
    Putting aside fine points concerning the application of the law, and
    returning to the general provisions of the tax law, it is presumed that all “gross
    receipts” are subject to the sales tax unless the contrary is established by the
    retailer. (§ 6091.) This presumption exists in order to ensure “the proper
    administration of [the sales tax law] and to prevent evasion of the sales tax . . . .”
    (Ibid.) Taxpayers’ exemption claims must be supported by adequate records.
    (Paine v. State Bd. of Equalization (1982) 
    137 Cal. App. 3d 438
    , 443 (Paine).) The
    burden of proof is on the taxpayer. (Southern California Edison Co. v. State Bd.
    of Equalization (1972) 
    7 Cal. 3d 652
    , 663 (Southern California Edison); People v.
    Schwartz (1947) 
    31 Cal. 2d 59
    , 64 (Schwartz).)
    2. Board jurisdiction over enforcement and tax challenges
    The Board administers and enforces the sales tax law (§§ 7051-7060), and
    adopts related regulations. (§ 7051.) It may audit taxpayers (§ 7054) and may
    require them to file reports relating to their sales. (§ 7055.) The Board, if not
    satisfied with the return or amount of tax paid, may make deficiency
    determinations (§ 6481), and impose penalties (§§ 6484, 6485), and may offset
    overpayments for one period against underpayments for another period or against
    penalties and interest. (§§ 6483, 6512.) The law provides the method by which
    retailers may challenge deficiency determinations made by the Board. (§§ 6561-
    6566.)
    Various rules govern the Board’s ability to file tax liens, undertake court
    actions, and execute judgments against taxpayers. (§§ 6701-6798.) The Board
    generally has three years from the time taxes are due or remitted to give notice of
    deficiency, but has eight years to act if no return is filed. (§ 6487, subd. (a).)
    Taxpayers may file refund claims with the Board. (§ 6901 et seq.)
    Taxpayers seeking a refund must first pay the tax; they may not deduct the
    disputed amount from their quarterly payments pending determination of the
    22
    refund claim. (Cal. Code Regs., tit. 18, § 5232, subd. (f).) Failure to file a timely
    refund claim constitutes a waiver of any claim for refund of overpayments.
    (§ 6905.) When it is determined that the taxpayer is owed a refund, the amount of
    excess tax payment is credited against amounts then due from the taxpayer.
    (§ 6901; Cal. Code Regs., tit. 18, § 5238.) The law imposes strict time limits on
    taxpayers for requests for refund or redetermination. (§§ 6561, 6902.)
    Taxpayers are subject to penalty for late or improper returns (§§ 6476-
    6478, 6591 et seq.), and may be criminally liable for false or fraudulent returns
    (§ 7152) or other violations of the tax code. (§§ 7153, 7153.5.)
    The taxpayer must exhaust administrative remedies before bringing an
    action in court. As the tax code provides, “[n]o suit or proceeding shall be
    maintained in any court for the recovery of any amount alleged to have been
    erroneously or illegally determined or collected unless a claim for refund or credit
    has been duly filed” pursuant to provisions of the tax code. (§ 6932.)
    The tax code also contains a provision that parallels article XIII, section 32
    of the state Constitution. It provides that “[n]o injunction or writ of mandate or
    other legal or equitable process shall issue in any suit, action, or proceeding in any
    court against this State or against any officer of the State to prevent or enjoin the
    collection under this part of any tax or any amount of tax required to be collected.”
    (§ 6931.)
    We have explained that “[t]he purpose of these statutory requirements is to
    ensure that the Board receives sufficient notice of the claim and its basis” and to
    give the Board “an opportunity to correct any mistakes, thereby conserving
    judicial resources.” 
    (Preston, supra
    , 25 Cal.4th at p. 206.) The issues raised in
    the claim for refund establish and restrict the claims that may be raised in any
    subsequent judicial challenge. (Ibid.)
    23
    3. Sales tax reimbursement
    As for consumers, although the sales tax falls on retailers and must be paid
    by them to the state, retailers are permitted but not required to obtain
    reimbursement for their tax liability from the consumer at the time of sale. (Civ.
    Code, § 1656.1; 9 Witkin, Summary of Cal. 
    Law, supra
    , Taxation, § 344, p. 498;
    56 
    Cal.Jur.3d, supra
    , Sales and Use Taxes, § 12, p. 25; 2 State Bd. of Equalization,
    Business Taxes Law Guide (2009) Sales & Use Tax Annots., Annots. Nos.
    460.0020, p. 4760 [retailers are not required to collect reimbursement], 460.0023,
    p. 4760 [retailers may discount a price by the amount of the sales tax
    reimbursement], 460.0005, p. 4759 [retailers may advertise a price as free of sales
    tax].) Whether a reimbursement amount will be added is purely a matter of
    contract between the retailer and consumer. (Civ. Code, § 1656.1, subd. (a); Cal.
    Code Regs., tit. 18, § 1700, subd. (a)(1).) It is presumed that the parties agreed to
    the addition of sales tax reimbursement to the sales price if the sales agreement so
    states, if the sales tax reimbursement is shown on the sales check, or if the retailer
    posts a notice or notifies consumers by specified methods that reimbursement for
    sales tax will be added to the sales price of all items or certain items. (Civ. Code,
    § 1656.1, subd. (a)(1), (2) & (3); 9 Witkin, Summary of Cal. 
    Law, supra
    ,
    Taxation, § 344, p. 498.)
    A retailer who fails to remit to the Board the sales tax reimbursement
    amount it has knowingly collected from the consumer is subject to a 40 percent
    penalty (§ 6597, subd. (a)(1) [“Any person who knowingly collects sales tax
    reimbursement . . . , and who fails to timely remit that sales tax reimbursement . . .
    to the board, shall be liable for a penalty of 40 percent of the amount not timely
    remitted”]; see 
    id., subd. (a)(2)
    [providing for certain exceptions].)
    Reimbursement amounts are deducted from the sales price for the purpose
    of calculating gross receipts, but only if the retailer establishes that the tax was
    24
    added to the sales price and was not absorbed by the retailer. (§ 6012, subd.
    (c)(12) [“For purposes of the sales tax, if the retailers establish to the satisfaction
    of the board that the sales tax has been added to the total amount of the sale price
    and has not been absorbed by them, the total amount of the sale price shall be
    deemed to be the amount received exclusive of the tax imposed. Section 1656.1 of
    the Civil Code shall apply in determining whether or not the retailers have
    absorbed the sales tax”].)8
    The corollary is that if the retailer “absorb[s]” the sales tax, the retailer
    owes the state tax on the full price. Sometimes the taxability of a sale depends on
    the identity of the purchaser, but it appears that nevertheless, for convenience,
    retailers in some instances may sell items at a single price to all buyers. For
    example, food bought from vending machines by students is exempt from tax (Cal.
    Code Regs., tit. 18, § 1574, subd. (b)(2)(D)), but the same purchase from the same
    machine by someone else on the school property is taxable. (Id., subd. (b)(2)(A).)
    The amicus curiae brief filed by the Board posits that as far as the consumer
    is concerned, for economic purposes, the sales tax reimbursement charge is part of
    the price paid by the consumer. The Board suggests that “[a]ny retailer who tried
    to over-collect sales tax reimbursement from its customers would quickly find
    them going to another retailer whose prices were lower.”
    4. Potential return to consumers of reimbursement charges
    As stated, plaintiffs’ UCL and CLRA claims rest on the premise that Target
    violated the tax code by charging them a reimbursement amount on a retail sale
    8       It is the retailer’s burden to rebut the presumption that sales tax was added
    to the sale price. (Cal. Code Regs., tit. 18, § 1667, subd. (a).) The presumption
    may be rebutted “by establishing to the satisfaction of the Board” that the sale was
    not subject to tax. (Ibid.)
    25
    that they allege was exempt from taxation. Before we analyze the current
    statutory provision governing excess reimbursement charges (§ 6901.5), we
    review the law that preceded it in order to understand the relative positions held in
    the statutory scheme by the consumer, the Board, and the taxpayer.
    a. Early law
    Prior law imposed the sales tax on retailers but stated that the “tax hereby
    imposed shall be collected by the retailer from the consumer in so far as it can be
    done” (former § 6052, added by Stats. 1941, ch. 36, § 1, p. 536), and prohibited
    the retailer from advertising that it would absorb, omit, or refund the tax. (Former
    § 6053, added by Stats. 1941, ch. 36, § 1, p. 536.) As explained post, in part
    II.B.4.f., eventually, in 1978, these provisions were repealed because they were
    seen as potentially but inaccurately suggesting that it was the consumer who was
    the taxpayer, not the retailer.
    b. Former section 6054.5
    In the meantime, in 1961 the Legislature added a provision that to some
    extent recognized consumer interests. Former section 6054.5 provided that if the
    retailer knowingly collected excess reimbursement, the amount should be refunded
    to the consumer or paid to the Board, and that the Board could condition a refund
    to the taxpayer on his or her payment of a refund to the consumer. It stated in
    pertinent part: “When an amount represented by a person to a customer as
    constituting reimbursement for taxes due under this part is computed upon an
    amount that is not taxable or is in excess of the taxable amount and is actually paid
    by the customer to the person, the amount so paid shall be returned by the person
    to the customer upon notification by the Board of Equalization or by the customer
    that such excess has been ascertained. In the event of his failure or refusal to do
    so, the amount so paid, if knowingly computed by the person upon an amount that
    is not taxable or is in excess of the taxable amount, shall constitute an obligation
    26
    due from him to this State. Such obligation may be determined and collected by
    the board in accordance with Chapters 5 and 6 of this part. The amount so
    collected shall be refunded by the board to the [taxpayer] . . . only upon
    submission of proof to the satisfaction of the board, or in the event the board
    denies his claim for refund, to the satisfaction of the superior court, that such
    amount has been returned or will be returned to the customer.” (Former § 6054.5,
    added by Stats. 1961, ch. 872, § 1, p. 2289, italics added.)
    c. Decorative Carpets
    We commented upon the customer’s equitable interest in a refund of excess
    reimbursement amounts in Decorative Carpets, Inc. v. State Board of Equalization
    (1962) 
    58 Cal. 2d 252
    (Decorative Carpets), in which we also discussed former
    section 6054.5, enacted during the pendency of litigation in that case. In
    Decorative Carpets, the taxpayer was a retail seller and also an installer of carpets.
    It mistakenly believed it was liable for tax on the total amount it charged the
    customer for the installed carpet. In fact, as an installer it was merely liable for
    sales tax on the installed-carpet transaction based on the amount it had paid the
    wholesaler for the carpet. “Because of its misunderstanding as to the proper
    method of computing the tax, plaintiff collected from its customers and paid to
    [the Board] $4,337.45 more than it should have collected and paid.” (Id. at
    p. 254.)
    The taxpayer filed a claim for refund from the Board of the excess it had
    collected and paid, but it sought the refund for itself and did not intend to make
    any refund to its customers. The Board responded that the taxpayer would be
    unjustly enriched if it could gain a refund of the excess it had paid without making
    a corresponding refund to customers to whom it had charged the full, excessive
    reimbursement amount.

    We commented that even without reference to former section 6054.5, an
    erroneously computed and collected sales tax reimbursement amount is in some
    sense held in constructive trust, either by the retailer or, if the sum has been
    remitted to the state, by the state. (Decorative 
    Carpets, supra
    , 58 Cal.2d at
    pp. 254-255.) We said that if the Board were treated as legally holding the excess
    tax payment in constructive trust for consumers, the ordinary result would be that
    the Board would be obliged to restore the amount in excess of the installer’s
    correct tax liability to the taxpayer’s customers. We explained, however, that such
    a direct remedy for consumers would be inappropriate, given the procedures
    established in the tax code. As we said: “[The Board’s] liability to refund taxes
    erroneously collected, however, is governed by statute [citation] and the orderly
    administration of the tax laws requires adherence to the statutory procedures and
    precludes imposing on [the Board] the burden of making refunds to the taxpayer’s
    customers.” (Id. at p. 255, italics added.)
    At the same time, we said, the Board bears some responsibility to
    consumers when excess sales tax has been remitted to it, given its “vital interest in
    the integrity of the sales tax.” (Decorative 
    Carpets, supra
    , 58 Cal.2d at p. 255.)
    Moreover, “[t]o allow plaintiff [taxpayer] a refund without requiring it to repay its
    customers the amounts erroneously collected from them would sanction a misuse
    of the sales tax by a retailer for his private gain.” (Ibid.)
    The Decorative Carpets case fell outside the new statutory provision
    regarding conditional refunds, not only because the enactment was adopted during
    the litigation but also because the claim involved a mistaken, not a knowing excess
    charge. We pointed out, however, that “the Legislature has never provided that
    customers are not entitled to recover from retailers amounts erroneously charged
    to cover sales taxes” (Decorative 
    Carpets, supra
    , 58 Cal.2d at p. 256, italics
    added) and that it was, prior to enactment of the statute, and remained, subsequent
    28
    to its enactment, “left to the courts to adopt appropriate remedies when excessive
    reimbursements have been collected by mistake and paid to the state.” (Ibid.) We
    concluded that it would be best to model our remedy on that provided specifically
    in former section 6054.5 — a refund to the taxpayer conditioned on proof
    satisfactory to the court that the taxpayer would refund the excess reimbursement
    to consumers. (Decorative 
    Carpets, supra
    , at p. 255.)
    In sum, our decision acknowledged that courts must recognize that “the
    orderly administration of the tax laws” requires that consumer remedies be
    consonant with procedures set out in the tax code. (Decorative 
    Carpets, supra
    , 58
    Cal.2d at p. 255.) At the same time, our decision found that consumers had some
    undefined equitable interest in a refund of excess reimbursement charges, and that
    the Board bore some responsibility to consumers when excessive sales tax
    amounts have been remitted to it, given its “vital interest in the integrity of the
    sales tax,” and the risk that an unconditional refund to the taxpayer/retailer could
    permit unjust enrichment for the retailer. (Ibid.)
    d. 1968 amendment to former section 6054.5
    In 1968, the Legislature amended former section 6054.5 to remedy the
    omission we had identified in Decorative Carpets and to provide for situations in
    which the taxpayer mistakenly, as opposed to knowingly, charged excess
    reimbursement. The amended statute provided that if the retailer charged
    reimbursement that mistakenly exceeded his or her own proper tax liability on the
    sale, the retailer could refund the amount to the consumer, but if not, the full
    amount collected had to be remitted to the state, which in turn could condition
    refunds to taxpayers on proof that the amount that exceeded tax liability would be
    refunded to customers. Thus the first two sentences of the statute were retained
    but separated and designated as subdivision (a), and two new subdivisions were
    added: “(b) When transactions occur during any period for which a return is
    29
    required to be filed and the total of the amounts represented by a person to his
    customers as constituting reimbursement for taxes due under this part with respect
    to those transactions exceed the taxes due from the person measured by his gross
    receipts during that period, the excess, if paid by and not returned to the
    customers, shall constitute an obligation due from the person to this state. The
    provisions of this subdivision shall apply when the amounts are mistakenly and
    not knowingly computed upon amounts that are not taxable or are in excess of the
    taxable amounts. [¶] (c) The obligations specified in subdivisions (a) and (b)
    may be determined and collected by the board in accordance with Chapters 5 and
    6 of this part. The amount so collected shall be refunded by the board to the
    person in accordance with Chapter 7 of this part, only upon submission of proof to
    the satisfaction of the board, or in the event the board denies his claim for refund,
    to the satisfaction of the superior court, that such amount has been returned or will
    be returned to his customers.” (Former § 6054.5, as amended by Stats. 1968, ch.
    501, § 1, pp. 1143-1144.)
    e. Javor
    The 1968 amendment of former section 6054.5 was followed by our
    decision in 
    Javor, supra
    , 
    12 Cal. 3d 790
    . In that case, Congress had repealed a
    federal excise tax imposed on manufacturers for the sale of new vehicles and
    accessories. The repeal was retroactive and federal law required manufacturers
    who obtained the benefit of the repeal to make refunds to purchasers. Although
    purchasers received those refunds, they also had been charged excess state sales
    tax reimbursement amounts. This was because the retailers who had sold them the
    vehicles had themselves paid state sales tax on a base price that included — now
    inappropriately — the federal excise tax, and had collected reimbursement from
    consumers in an amount that included that inappropriate amount. The Board
    adopted a rule reducing the amount of the retailer’s taxable gross receipts to reflect
    30
    the refund of the federal excise tax to consumers and providing that accordingly,
    the excess in “the sales tax will be refunded [by the Board] to the retailer provided
    [the retailer] also repays to the consumer the amount collected from [the
    consumer] as sales tax reimbursement.” (
    Javor, supra
    , 12 Cal.3d at p. 794.)
    Plaintiff, a purchaser of a new vehicle, sought to bring a class action against
    the Board and automobile retailers, alleging claims for money due and an
    accounting.9 The plaintiff/consumer alleged that he had no remedy under the tax
    code. He pointed out that there was no statutory requirement that
    taxpayer/retailers seek a refund from the Board, nor was there a financial incentive
    for them to do so because the Board would simply require them to refund the
    excess to customers. He urged that a class should be certified to avoid requiring
    each member of the class to require each individual retailer to seek a refund from
    the Board. (
    Javor, supra
    , 12 Cal.3d at pp. 795, 797.) The plaintiff urged that
    under these unique circumstances, the court should fashion a remedy.
    We turned to the general principle stated in Decorative Carpets that under
    ordinary constructive trust principles, the Board would hold mistakenly computed
    tax payments in constructive trust. (
    Javor, supra
    , 12 Cal.3d at p. 798.) As in our
    earlier decision we observed, however, that notwithstanding ordinary principles
    governing constructive trusts, the Board’s liability is governed by the tax code and
    that “ ‘the orderly administration of the tax laws requires adherence to the
    statutory procedures and precludes imposing on [the Board] the burden of making
    refunds to the taxpayer’s customers.’ ” (Id. at p. 798, italics added.) Still, we
    9      The complaint named as defendants the Board, the State of California, a car
    dealership, and “all” California retailers of new vehicles. Our opinion noted,
    however, that “the Board is the only defendant either served with summons or
    appearing in the action.” (
    Javor, supra
    , 12 Cal.3d at p. 793 & fn. 2.)
    31
    reiterated that “ ‘the Legislature has never provided that customers are not entitled
    to recover from retailers amounts erroneously charged to cover sales taxes.’ ” (Id.
    at p. 799, italics added.)
    When we decided 
    Javor, supra
    , 
    12 Cal. 3d 790
    , the 1968 amendment to
    former section 6054.5 already authorized the Board to condition a refund for tax
    for which a mistaken reimbursement charge had been collected on proof that a
    refund had or would be made to consumers, but it did not prescribe a remedy when
    the retailer had paid the excess to the Board and had not sought a refund. (
    Javor, supra
    , at p. 800.) As there was no direct statutory provision for consumer refunds
    when taxpayers failed to seek a refund, we said that “we find ourselves in the same
    position as the court in Decorative Carpets and must fashion an appropriate
    remedy to effect the customers’ right to their refund which is consonant with
    existing statutory procedures.” (Ibid., italics added)
    We agreed with the Board that it would not be consonant with the tax code
    or Decorative Carpets to fashion a remedy that would give consumers a cause of
    action against the Board for the excess amounts the retailer had paid in taxes.
    (
    Javor, supra
    , 12 Cal.3d at p. 800.) Nonetheless, we said, “in respect to the
    customer’s right to be reimbursed by the retailer, the Board is not a neutral or
    disinterested party for two reasons: First it has a vital interest in the integrity of
    the sales tax and therefore a responsibility to customers who are entitled to a
    refund; and, second, it holds the excessive monies collected by the retailers who
    paid them to the Board and it is not entitled to them. Section 6054.5 and
    Decorative Carpets make it clear that both the Legislature and the courts have
    placed a duty upon the Board to see that the customer eventually obtains any
    refund [the Board] made to the retailer. Although . . . this duty may stop short of
    compelling the Board to repay the customers directly, nevertheless the Board
    cannot use the refund procedure to abdicate its responsibility to the customer,
    32
    particularly where the Board stands to unjustly profit under such circumstances.”
    (
    Javor, supra
    , at p. 800.)
    Of significance to the present case, we also recognized that under existing
    procedures, “the retailer is the only one who can obtain a refund from the Board,”
    but observed that because the retailer cannot retain the excess tax amount for
    itself, but must undertake some procedure to make refunds to customers, it may
    have no particular interest in pursuing a tax refund. (
    Javor, supra
    , 12 Cal.3d at
    p. 801.) Similarly, the Board may lack incentive to examine returns on its own
    initiative to determine whether retailers have remitted excess taxes to it — that is,
    whether taxes have been overpaid. (Ibid.) We observed that the Board “is very
    likely to become enriched at the expense of the customer to whom the amount of
    the excessive tax actually belongs.” (Id. at p. 802.)
    We pointed out that the Board had issued instructions to retailers that they
    were entitled to refund of the excess sales tax provided they returned the refund to
    the customer. The Board’s procedure initially required the retailer to pay the
    refund to the customer and then claim a refund from the Board, but the Legislature
    enacted special legislation so that for a period of approximately a year, retailers
    could avoid the refund process with the Board and simply claim a tax credit for the
    amount it had refunded to customers. Once that special provision expired, again
    the retailer was “the only one who can obtain a refund from the Board; yet, since
    the retailer cannot retain the refund himself, but must pay it over to his customer,
    the retailer has no particular incentive to request the refund on his own.” (
    Javor, supra
    , 12 Cal.3d at p. 801.)10
    10     We commented in passing that for the period during which the short-lived
    special statute had provided that retailers could simply claim a credit for the
    excess tax they had paid based on the federal excise provision, without the need
    (footnote continued on next page)
    33
    We explained the remedy we adopted as follows: “[P]urchasers can most
    effectively enforce their refund right by compelling retailers to claim their own
    refunds from the Board. The Board has admitted that it must pay these refunds to
    retailers. All that plaintiffs seek in this action is to compel defendant retailers to
    make refund applications to the Board and in turn to require the Board to respond
    to these applications by paying into court all sums, if any, due defendant retailers.
    [¶] We think that to require this minimal action from the Board is clearly
    mandated by the Board’s duty to protect the integrity of the sales tax by ensuring
    that the customers receive their refunds. The integrity of the sales tax requires not
    only that the retailers not be unjustly enriched [citation], but also that the state not
    be similarly unjustly enriched.” (
    Javor, supra
    , 12 Cal.3d at p. 802.)
    Our holding in Javor was limited to what we saw as “unique
    circumstances”: “We hold that under the unique circumstances of this case a
    customer, who has erroneously paid an excessive sales tax reimbursement to his
    retailer who has in turn paid this money to the Board, may join the Board as a
    party to his suit for recovery against the retailer in order to require the Board in
    response to the refund application from the retailers to pay the refund owed the
    retailers into court or provide proof to the court that the retailer had already
    (footnote continued from previous page)
    for a refund action to establish their own right to refund, consumers could have
    sued the retailers who had claimed such a credit for refund. (
    Javor, supra
    , 12
    Cal.3d at p. 802.) Our comment does not explain the legal basis of such an action,
    and former section 6054.5 no longer is in effect. Under current law, the taxpayer
    may remit the funds to the Board if he or she decides not to issue refunds to
    consumers. (§ 6901.5.) Moreover, in Javor, there was no controversy over the
    taxability question — it was agreed that an excess had been collected and the
    amount of the excess also was not in dispute.
    34
    claimed and received a refund from the Board. We think that allowing the Board
    to be joined as a party for these purposes in the customer’s action against the
    retailer is an appropriate remedy entirely consonant with the statutory procedures
    providing for a customer’s recovery of erroneously overpaid sales tax.” (
    Javor, supra
    , 12 Cal.3d at p. 802, fn. omitted.)
    f. Repeal of former section 6054.5
    In 1978, four years after we decided 
    Javor, supra
    , 
    12 Cal. 3d 790
    , former
    section 6054.5 was repealed. (Stats. 1978, ch. 1211, § 8, p. 3922.) The repeal
    occurred as part of a revision of the tax code that was intended to clarify that the
    incidence of the state sales tax is on retailers, not consumers. In the earlier tax
    system, some ambiguity had arisen about who was the real taxpayer for sales tax
    purposes. Even though we had affirmed that the tax fell upon the retailer, we
    acknowledged that some elements of the law could be interpreted to suggest
    otherwise. (National Ice etc. Co. v. Pacific F. Ex. Co. (1938) 
    11 Cal. 2d 283
    , 286.)
    When a federal decision found that the California sales tax fell on a bank as a
    purchaser (see Diamond National v. State Equalization Bd. (1976) 
    425 U.S. 268
    ),
    the revision was considered necessary. (Stats. 1978, ch. 1211, § 19, p. 3925; 9
    Witkin, Summary of Cal. 
    Law, supra
    , Taxation, § 344, p. 498.) The 1978
    enactment clarified that the tax fell on the retailer “by removing from the code
    those provisions of law which have characteristics of laws which impose the tax
    upon the consumer.” (Assem. Com. on Rev. & Tax., Analysis of Sen. Bill 472
    (1977-1978 Reg. Sess.) as amended June 15, 1977, p. 3, italics added; see also 9
    Witkin, supra, § 344, pp. 497-498; Selected 1978 California Legislation (1979) 10
    Pacific L.J. 247, 585.) It repealed the former tax code provisions that had been
    seen as essentially requiring the retailer to collect reimbursement from customers
    and that plainly made it unlawful for the retailer to advertise that he or she would
    absorb the tax. (See former §§ 6052, 6053, repealed by Stats. 1978, ch. 1211, §§ 4
    35
    & 6, p. 3922, and see Historical and Statutory Notes, 59B West’s Ann. Rev. &
    Tax. Code (1998 ed.) notes to former §§ 6052 to 6054.5, p. 468.) Of note for the
    present case, the enactment also repealed former section 6054.5, with its apparent
    concern for consumers. All of these repealed provisions evidently were thought to
    create a danger that they might support the view that consumers bore the economic
    burden of the tax and therefore were the actual taxpayers.
    In their place, the Legislature added Civil Code section 1656.1, described
    above, permitting but not requiring the addition of reimbursement charges,
    designating the charges as a matter for a contractual agreement between seller and
    buyer, and permitting the retailer to absorb the tax. (Stats. 1978, ch. 1211, § 1,
    pp. 3915-3917; see Assem. Com. on Rev. & Tax., Analysis of Sen. Bill 472
    (1977-1978 Reg. 
    Sess.), supra
    , as amended June 15, 1977, pp. 1-3; Selected 1978
    California 
    Legislation, supra
    , 10 Pacific L.J. at pp. 585-588.)
    As described by the Board in an administrative memo issued shortly after
    the repeal of former section 6054.5, with the repeal the law returned to its state
    prior to the enactment of former section 6054.5. The Board explained that with
    the repeal, it would “have no statutory duty to police the retail trade to ensure that
    only the correct amount of tax reimbursement is collected from the customers on
    retail sales. The repeal of section 6054.5 removes the authority for the Board to
    req[u]ire the retailer to either refund the excess reimbursement to the customer or
    pay it to the Board. [¶] However, in situations where the retailer has paid excess
    reimbursement to the Board and then seeks a refund, the legal staff believes the
    Board would be justified in refusing to refund the excess tax unless the retailer
    agrees to refund the tax to his customers. This is the Decorative Carpets . . . fact
    situation, which was decided on the law as it read prior to the addition of Section
    6054.5.” (State Bd. of Equalization, Operations Memo No. 611 (Oct. 23, 1978)
    p. 4 [on passage of Sen. Bill No. 472 (1977-1978 Reg. Sess.)].) The Board’s
    36
    reliance on Decorative 
    Carpets, supra
    , 
    58 Cal. 2d 252
    , seems well founded, given
    our recognition in that case that even without former section 6054.5, consumers
    had some undefined equitable interest in refund of excess reimbursement and that,
    consistently with tax code provisions, the Board could condition taxpayer refunds
    on return of excess reimbursement payments to consumers. (See Decorative
    
    Carpets, supra
    , at pp. 254-255.)
    g. Section 6901.5 — current law
    Four years later, in 1982, section 6901.5 was added to the tax code (Stats.
    1982, ch. 708, § 2, p. 2867) and a minor revision in 1987 brought it to its current
    form. (Stats. 1987, ch. 38, § 4, p. 101.) The provision repeats the first and part of
    the second sentences of former section 6054.5, subdivision (a), language we had
    interpreted in Decorative Carpets as confirming that the Legislature viewed the
    consumer as having some equitable interest in a return of excess reimbursement
    charges but significantly, as we shall see, the provision also affords a safe harbor
    for retailers who remit the amounts to the Board. Thus section 6901.5 provides:
    “When an amount represented by a person to a customer as constituting
    reimbursement for taxes due under this part is computed upon an amount that is
    not taxable or is in excess of the taxable amount and is actually paid by the
    customer to the person, the amount so paid shall be returned by the person to the
    customer upon notification by the Board of Equalization or by the customer that
    such excess has been ascertained. In the event of his or her failure or refusal to
    do so, the amount so paid, if knowingly or mistakenly computed by the person
    upon an amount that is not taxable or is in excess of the taxable amount, shall be
    remitted by that person to this state. Notwithstanding subdivision (b) of Section
    6904 [concerning class claims], those amounts remitted to the state shall be
    credited by the board on any amounts due and payable under this part on the same
    transaction from the person by whom it was paid to this state and the balance, if
    37
    any, shall constitute an obligation due from the person to this state.” (§ 6901.5,
    italics added.) In an uncodified section of the original enactment, the Legislature
    stated that the addition of section 6901.5 to the code was intended “to make a
    procedural change in the manner in which the sales tax is remitted and to affect all
    applicable pending proceedings.” (Stats. 1982, ch. 708, § 4, p. 2868.)
    The legislative history of the enactment is obscure. Section 6901.5 was
    appended to a bill on a different topic — the bill initially provided a sales tax
    exemption for sale of donated clothing. (See Assem. Bill No. 2619 (1981-1982
    Reg. Sess.), as amended Feb. 11, 1982.) The Board opposed this exemption. (See
    Sen. Democratic Caucus, 3d reading analysis of Assem. Bill No. 2619, as
    amended Aug. 17, 1982, p. 2; see also Board’s letter to Gov. Edmund G. Brown re
    Assem. Bill No. 2619 (1981-1982 Reg. Sess.) Sept. 7, 1982, pp. 3-4.) When the
    bill progressed to the Senate, section 6901.5 was added. (See Assem. Bill
    No. 2619 (1981-1982 Reg. Sess.) as amended Aug. 17, 1982.) The Senate
    amendment was described as “altering the manner in which sales tax amounts are
    remitted to the state.” (Assem. Off. of Research, Concurrence in Sen. Amends. to
    Assem. Bill No. 2619 (1981-1982 Reg. Sess.) as amended Aug. 17, 1982, p. 1; see
    also Dept. of Finance, Enrolled Bill Rep. on Assem. Bill No. 2619 (1981-1982
    Reg. Sess.) as amended Aug. 17, 1982, p. 2 [the bill “makes procedural changes in
    the manner in which the sales and use tax is remitted by providing that the retailer
    return to the customer any sales or use tax mistakenly collected. If the retailer
    fails to issue a refund to the customer, the [amount] must be remitted to the Board
    of Equalization. A credit will then be issued by the [Board] against the retailer’s
    current obligation on the same transaction”].)
    In its operations memo concerning the new provision, the Board expressed
    its view concerning the safe harbor afforded by the statute, asserting that by
    enacting section 6901.5, the Legislature intended “to allow a taxpayer to satisfy
    38
    his or her tax liability on a transaction by paying to the State an equivalent amount
    of tax reimbursement collected from a customer on the same transaction.” (State
    Bd. of Equalization, Operations Memo No. 754 (Jan. 12, 1983), p. 1 [on passage
    of Assem. Bill No. 2619 (1981-1982 Reg. Sess.)] (Board Operations Memo No.
    754).) In other words, “[t]ax reimbursement collected from a customer on a
    transaction is excessive only to the extent that it exceeds the taxpayer’s own tax
    liability on the same transaction.” (Id., p. 2.)
    In the same operations memo, the Board emphasized that “[i]f tax
    reimbursement in excess of the tax liability on a transaction is collected and paid
    to the State, the taxpayer has no further tax liability . . . .” (Bd. Operations Memo
    No. 754, supra, p. 1.) As for procedure, if the taxpayer pays the amount collected
    and seeks a refund, “any refund will be limited to the amount paid to the State in
    excess of the tax liability.” (Ibid.) If the taxpayer does not remit the amount, the
    Board explained that “[i]f an audit discloses that tax reimbursement was collected
    in excess of the tax liability on the transaction, and that no tax has been paid to the
    State on the transaction, the tax liability will be assessed and the tax
    reimbursement in excess of that amount must be returned to the customer or paid
    to the State.” (Ibid., italics added.) The Board added that reimbursement amounts
    that exceed the taxpayer’s liability “must be returned to the customer. If the
    taxpayer fails or refuses to return such excess tax reimbursement to the customer,
    it must be paid to the State whether it was mistakenly computed or knowingly
    computed.” (Id., p. 2.)
    Section 6901.5 makes plain that the retailer is not permitted to retain excess
    sales tax reimbursement amounts. Indeed, the Board evidently saw this as a
    change. In connection with the possible retrospective operation of section 6901.5,
    the Board stated that during the period after section 6054.5 was repealed, “there
    was no requirement . . . that ‘excess tax reimbursement’ be paid to the state . . . .”
    39
    (Bd. Operations Memo No. 754, supra, p. 3.) Under the terms of section 6901.5,
    however, the excess must be returned to consumers or remitted to the Board.
    Based upon the statutory language, it appears that a retailer may refuse a
    consumer’s request that excess reimbursement be refunded, so long as the retailer
    remits the amount to the Board. It follows that the taxpayer reaches a safe haven
    vis à vis the consumer if it pays the sums to the Board.
    Section 6901.5 also refers to a return of excess reimbursement charges to
    consumers once it has been, in the words of the statute, “ascertained” that an
    excess has been charged. Under the procedures established by the code, the Board
    could “ascertain” whether excess reimbursement was charged during an audit (see
    § 7054), a deficiency determination proceeding (see §§ 6481-6483), or Board
    consideration of a taxpayer’s claim for refund. (§ 6901 et seq.) Section 6901.5
    provides no procedure by which consumers can require the Board to “ascertain”
    whether excess reimbursement has in fact been charged, nor is there a statutory
    procedure by which the consumer can make certain that the retailer will be ordered
    to refund an excess amount to the consumer.
    The Board’s Business Taxes Law Guide repeats the Board’s view that,
    under section 6901.5, once the retailer has remitted the tax in the amount of the
    excess tax reimbursement to the state, the retailer’s obligations are at an end. This
    guide also demonstrates that the Board contemplates that it is the retailer/taxpayer,
    not the consumer, who has standing to request any refund of amounts that have
    been remitted to the Board. (2 State Bd. of Equalization, Business Taxes Law
    
    Guide, supra
    , Annot. No. 460.0028, at pp. 4762-4763; see Yamaha Corp. of
    America v. State Bd. of Equalization (1998) 
    19 Cal. 4th 1
    , 7-8 (Yamaha) [a court
    analyzing a statute may take the Board’s annotations into account, but they are not
    binding as quasi-legislative rules].)
    40
    Specifically, the annotation states that when it has been “determined” that a
    retailer collected excess reimbursement, retailers “must either refund the money to
    the customer(s) or remit it to the State. . . . [¶] In circumstances where the retailer
    has filed its returns for the applicable tax quarter and remitted the monies to the
    State, it has complied with its duties under the Sales and Use Tax Law as to sales
    tax reimbursement. Once the retailer has remitted the tax reimbursement to the
    Board, the sole legal avenue available for determining the proper application of
    tax is for the retailer to submit a claim for refund under section 6901 . . . [the
    general statute governing refunds]. . . . The Board may only grant a tax refund to
    the person who paid the tax. If the Board were to deny the claim for refund, the
    retailer could pursue an action in court for refund of sales tax under section 6933.
    There is no provision in the law for an action on the part of a nontaxpayer to
    dispute the application of tax.” (2 State Bd. of Equalization, Business Taxes Law
    
    Guide, supra
    , Annot. No. 460.0028, pp. 4762-4763, italics added.)11
    h. “Regulation 1700(b)(2)” (Cal. Code Regs., tit. 18, § 1700, subd. (b)(2))
    The regulation adopted to carry out the terms of section 6901.5, section
    1700, subdivision (b)(2) of title 18 of the California Code of Regulations,
    amplifies the statute and offers some guidance on the situation in which excess
    11      The annotations also suggest that a retailer may avoid the need to make
    refunds to consumers if it advises consumers in advance that the price for the
    particular sale includes a reimbursement amount. In other words, the retailer
    charges the same price to the consumer, but by “absorbing” the tax itself within
    that price, the retailer excludes the consumer from the tax altogether even though
    the consumer pays the same price. This is achieved by posting a sign that “all
    prices include applicable sales tax.” (2 State Bd. of Equalization, Business Taxes
    Law 
    Guide, supra
    , Annot. No. 460.0149, at p. 4766.) According to an amicus
    curiae brief filed by the Board in this case, the Board informally advised Target to
    use this mechanism to avoid problems in the future.
    41
    sales tax reimbursement has been collected. The regulation makes it plain that the
    consumer’s refund is dependent upon the Board first taking action to “ascertain[]”
    that the amount charged was excessive. The implication is that ordinarily it would
    be in the course of an audit, refund, or deficiency determination proceeding that
    the Board would “ascertain[]” that excess reimbursement amounts had been
    collected. In the case of an audit or deficiency determination, once the Board
    “ascertains” that an excess charge was made, the retailer is given the option to
    make a refund to the customer. If the retailer declines, the amount must be
    remitted to the state. The Board will make a determination against the retailer for
    any reimbursement amount that the retailer failed to remit to the state, adding
    applicable interest and penalties. Excess tax reimbursements are offset against the
    taxpayer’s tax liability on the same transaction. The regulation provides in
    pertinent part as follows:
    “(1) Definition. When an amount represented by a person [i.e., a
    retailer/taxpayer] to a customer as constituting reimbursement for sales tax is
    computed upon an amount that is not taxable or is in excess of the taxable amount
    and is actually paid by the customer to the person, the amount so paid is excess tax
    reimbursement. Excess tax reimbursement is charged when reimbursement is
    computed on a transaction which is not subject to tax, when reimbursement is
    computed on an amount in excess of the amount subject to tax, when
    reimbursement is computed using a tax rate higher than the rate imposed by law,
    and when mathematical or clerical errors result in an overstatement of the
    reimbursement on a billing.
    “(2) Procedure upon Ascertainment of Excess Tax Reimbursement.
    Whenever the board ascertains that a person [i.e., a retailer/taxpayer] has
    collected excess tax reimbursement, the person will be afforded an opportunity to
    refund the excess collections to the customers from whom they were collected. In
    42
    the event of failure or refusal of the person to make such refunds, the board will
    make a determination against the person for the amount of the excess tax
    reimbursement collected and not previously paid to the state, plus applicable
    interest and penalty.” (Cal. Code Regs., tit. 18, § 1700, subd. (b)(1) & (2), italics
    added.)
    Various additional provisions govern offsets, which may be claimed by the
    taxpayer when he or she files a return, during deficiency determinations, or in
    refund proceedings. The regulation provides that “[i]f a person who has collected
    excess tax reimbursement on a transaction fails or refuses to refund it to the
    customer from whom it was collected, the excess tax reimbursement shall be
    offset against any tax liability of the taxpayer on the same transaction. Any excess
    tax reimbursement remaining after the offset must be refunded to the customer or
    paid to the state. The offset can be made when returns are filed, when a
    determination is issued, or when a refund is claimed.” (Cal. Code Regs., tit. 18,
    § 1700, subd. (b)(4), italics added.)
    The regulation states that the taxpayer’s ability to offset tax liability on a
    transaction by excess reimbursement amounts does not necessarily limit the
    consumer’s rights to a refund of the amount by which the reimbursement amounts
    collected exceeded the taxpayer’s proper sales tax liability. Under the heading
    “Rights of Customers,” the final paragraph of the regulation states: “The
    provisions of this regulation with respect to offsets do not necessarily limit the
    rights of customers to pursue refunds from persons who collected tax
    reimbursement from them in excess of the amount due.” (Cal. Code Regs., tit. 18,
    § 1700, subd. (b)(6).)12
    12    Retailers who choose to refund excess reimbursement rather than remit it to
    the Board must retain records to demonstrate they have or will return excess
    (footnote continued on next page)
    43
    Contrary to plaintiffs’ claim, this provision does not support the inference
    that the Board, without referring to consumer actions brought under the UCL or
    CLRA, by this language endorsed consumer actions against retailers for refund of
    reimbursement amounts charged on assertedly nontaxable sales. Rather, the
    regulation merely acknowledges that if other remedies are available, the regulation
    does not interfere with them. The regulation reasonably may be interpreted to
    refer to our recognition that, when neither the Board nor the taxpayer has an
    interest in “ascertaining” whether excess reimbursement has been charged, in
    limited circumstances consumers may file an action to require the taxpayer to seek
    a refund (see 
    Javor, supra
    , 
    12 Cal. 3d 790
    ), leading to a refund to the taxpayer
    conditioned on an appropriate refund to consumers. (See Decorative 
    Carpets, supra
    , 
    58 Cal. 2d 252
    .)
    The provision also means that the regulation does not bar other, more
    informal efforts on the part of consumers. In its amicus curiae brief in this court,
    (footnote continued from previous page)
    amounts to consumers. The regulation provides: “(A) If a person already has
    refunded to each customer amounts collected as reimbursement for tax in excess
    of the tax due, this may be evidenced by any type of record which can be verified
    by audit such as: [¶] 1. Receipts or cancelled checks. [¶] 2. Books of account
    showing that credit has been allowed the customer as an offset against an existing
    indebtedness owed by the customer to the person. [¶] (B) If a person has not
    already made sales tax reimbursement refunds to each customer but desires to do
    so rather than incur an obligation to the state, the person must: [¶] 1. Inform in
    writing each customer from whom an excess amount was collected that the excess
    amount collected will be refunded to the customer or that, at the customer’s
    option, the customer will be credited with such amount, and [¶] 2. The person
    must obtain and retain for verification by the board an acknowledgement from the
    customer that the customer has received notice of the amount of indebtedness of
    the person to the customer.” (Cal. Code Regs., tit. 18, § 1700, subd. (b)(3), italics
    added.)
    44
    the Board asserts that although no formal administrative procedure is available by
    which consumers may require the Board to “ascertain[]” whether excess
    reimbursement has been charged, consumers may complain informally to the
    Board if they believe they have been charged excess tax reimbursement. The
    Board’s amicus curiae brief notes that the agency’s customer service
    representatives filed a large volume of calls and emails from the public. (See Bd.
    of Equalization, 2009-2010 Annual Report, p. 24
     [as of May 1, 2014].)
    The brief also asserts that tips from informants may lead the Board to conduct an
    audit (see Bd. of Equalization, Dept. of Sales and Use Tax, Audit Manual,
    § 0122.02 < http://www.boe.ca.gov/sutax/manuals/am-01.pdf>[as of May 1,
    2014]) and that informal complaints could lead to a deficiency determination
    against the taxpayer. The Board also comments that consumers as “interested
    person[s]” may petition the Board to adopt, amend, or repeal a regulation (Gov.
    Code, § 11340.6), and that they may file a declaratory relief action that does not
    seek an adjudication of tax liability but merely challenges a regulation as
    inconsistent with statute or constitution. (Id., § 11350.) Nothing in the regulation
    would interfere with any of these remedies.
    5. Summary
    The above review of the sales tax scheme depicts a system that
    comprehensively regulates taxation on myriad types of transactions, and confirms
    that the Board is the entity responsible for determining in the first instance
    whether transactions, in their nearly infinite variety, are taxable and how much tax
    is due. This review has also demonstrated that it is the Board that “ascertains”
    whether a retailer has charged excess reimbursement on a sale and that a retailer
    may either refund excesses to consumers or remit them to the Board. It is the
    Board that is the entity charged with assuring the “integrity of the sales tax”
    45
    following statutory procedures assuring the “orderly administration of the tax
    laws.” (Decorative 
    Carpets, supra
    , 58 Cal.2d at p. 255; see 
    Javor, supra
    , 12
    Cal.3d at pp. 798, 800.)
    For reasons we shall explain in the next part, we conclude that permitting
    plaintiffs to use the UCL or CLRA to challenge Target’s collection of a sales tax
    reimbursement on the ground that the sale was not taxable is inconsistent with the
    tax code provisions relating to the sales tax, particularly in light of the primary
    role assigned to the Board with regard to the resolution of sales tax issues and the
    presumption that all sales are taxable unless the taxpayer demonstrates otherwise
    to the satisfaction of the Board. When a consumer claim such as plaintiffs’ is
    dependent upon the resolution of the taxability question, a UCL or CLRA lawsuit
    of this sort against the retailer is inconsistent with the method established by the
    Legislature as the exclusive means for ascertaining whether a transaction is subject
    to the sales tax. A consumer lawsuit in this context also is inconsistent with tax
    code procedures under which retailers may discharge their obligations by remitting
    any excess reimbursement charge to the Board.
    C. Are plaintiffs’ consumer claims inconsistent with the statutory sales
    tax system?
    Plaintiffs, joined by the Attorney General as amicus curiae, urge that the
    UCL affords consumers a broad form of action, that the remedies provided by the
    UCL are cumulative to other remedies “[u]nless otherwise expressly provided by
    law” (Bus. & Prof. Code, § 17205), and that UCL actions are recognized for
    conduct that violates a statute that itself provides for no private right of action.
    (See Stop Youth Addiction, Inc. v. Lucky Stores, Inc. (1998) 
    17 Cal. 4th 553
    , 562
    (Stop Youth Addiction).) They contend that the tax code does not specifically bar
    actions other than those recognized in that code. (See Cel-Tech Communications,
    Inc. v. Los Angeles Cellular Telephone Co. (1999) 
    20 Cal. 4th 163
    , 180, 183 (Cel-
    46
    Tech) [“To forestall an action under the unfair competition law, another provision
    must actually ‘bar’ the action”]; see also State of California v. Altus Finance
    (2005) 
    36 Cal. 4th 1284
    , 1303 & fn. 6 (Altus Finance) [“the fact that there are
    alternative remedies under a specific statute does not preclude a UCL remedy,
    unless the statute itself provides that the remedy is to be exclusive”; leaving open
    whether an implied repeal of UCL remedies occurs when the UCL and another
    statutory remedy are clearly repugnant and so inconsistent that both cannot apply];
    Stop Youth 
    Addiction, supra
    , at p. 573.)
    Plaintiffs also contend that because the tax code affords them no formal
    procedure by which to seek a refund of a reimbursement charge on a nontaxable
    sale, it is reasonable to conclude that their remedy lies elsewhere — with the UCL
    and CLRA. The Attorney General joins plaintiffs in urging the broad protections
    of the UCL and CLRA should be available to consumers who are charged for sales
    tax reimbursement on a nontaxable sale, emphasizing the absence of other
    measures requiring the Board or retailers to protect consumers, and claiming that
    the tax code and remedies under the consumer laws are not in direct conflict.
    We have explained that “[t]he UCL prohibits, and provides civil remedies
    for, unfair competition, which it defines as ‘any unlawful, unfair or fraudulent
    business act or practice.’ ([Civ. Code,] § 17200.) Its purpose ‘is to protect both
    consumers and competitors by promoting fair competition in commercial markets
    for goods and services.’ [Citations.] In service of that purpose, the Legislature
    framed the UCL’s substantive provisions in ‘ “broad, sweeping language . . . .” ’ ”
    (Kwikset Corp. v. Superior Court (2011) 
    51 Cal. 4th 310
    , 320 (Kwikset).) This
    may “ ‘include “ ‘anything that can properly be called a business practice and that
    at the same time is forbidden by law.’ ” ’ ” (Ibid.) In addition, a practice that is
    unfair or fraudulent may be the basis for a UCL action even if the conduct is “not
    47
    specifically proscribed by some other law.” 
    (Cel-Tech, supra
    , 20 Cal.4th at
    p. 180; see 
    id., at p.
    184.)
    The UCL was intended “ ‘to permit tribunals to enjoin on-going wrongful
    business conduct in whatever context such activity might occur’ ” and to “ ‘enable
    judicial tribunals to deal with the innumerable “ ‘new schemes which the fertility
    of man’s invention would contrive.’ ” [Citation].’ ” 
    (Cel-Tech, supra
    , 20 Cal.4th
    at p. 181.)
    As for the CLRA, it “makes unlawful . . . various ‘unfair methods of
    competition and unfair or deceptive acts or practices undertaken by any person in
    a transaction intended to result or which results in the sale or lease of goods or
    services to any consumer.’ These include . . . ‘[r]epresenting that a transaction
    confers or involves rights, remedies, or obligations which it does not have or
    involve, or which are prohibited by law’ . . . .” (Meyer v. Sprint Spectrum L.P.
    (2009) 
    45 Cal. 4th 634
    , 639 (Meyer); see Civ. Code, § 1770.) Like the UCL,
    CLRA remedies are not exclusive, but are “in addition to any other procedures or
    remedies for any violation or conduct provided for in any other law.” (Civ. Code,
    § 1752.)
    On the other hand, the reach of the UCL is broad, but it is not without limit
    and may not be used to invade “safe harbors” provided by other statutes. (Cel-
    
    Tech, supra
    , 20 Cal.4th at p. 182.) “Courts may not simply impose their own
    notions . . . as to what is fair or unfair. Specific legislation may limit the
    judiciary’s power to declare conduct unfair. If the Legislature has permitted
    certain conduct or considered a situation and concluded no action should lie,
    courts may not override that determination. When specific legislation provides a
    ‘safe harbor,’ plaintiffs may not use the general unfair competition law to assault
    that harbor.” (Ibid., italics added.) When a statute such as that defining the
    litigation privilege, for example, renders the conduct complained of immune from
    48
    tort liability, a plaintiff cannot use the UCL to “ ‘ “plead around” ’ ” that
    immunity. (Ibid.) “To forestall an action under the unfair competition law,
    another provision must actually ‘bar’ the action or clearly permit the conduct.”
    (Id. at p. 183, italics added.) As we further explained: “If, in the Unfair Practices
    Act (or some other provision), the Legislature considered certain activity in certain
    circumstances and determined it to be lawful, courts may not override that
    determination under the guise of the unfair competition law.” (Ibid.)
    These comments on statutory safe harbors are directly relevant in the
    present case. In express conflict with plaintiffs’ contention that defendant acted
    “unlawfully” within the meaning of the UCL when it represented that it properly
    was collecting and in fact collected reimbursement on assertedly nontaxable sales
    and failed to return the reimbursement charges to consumers, under the tax code
    retailers have an option either to refund to consumers any reimbursement charges
    the Board has ascertained are excessive or to remit the excess amounts to the
    Board. (§ 6901.5.) Retailers reach a safe harbor once they remit any excess
    reimbursement amount to the state — and of course follow any ensuing orders by
    the Board with respect to consumer refunds. Yet plaintiffs contend that their
    consumer action should lie whether or not the retailer has remitted the disputed
    amounts to the Board. Plaintiffs’ UCL claim is premised on a hypothetical system
    under which the retailer/taxpayer must refund excess amounts directly to
    consumers — without any effort on the part of the Board to “ascertain[]” whether
    there was indeed excess reimbursement collected. This is not the system currently
    established by the tax code. The UCL cannot properly be interpreted to impose on
    retailers a duty with respect to sales tax that is contradicted by the statutory
    scheme governing the sales tax. (See, e.g., In re Tobacco Cases II (2007) 
    41 Cal. 4th 1257
    , 1273 [the plaintiffs’ UCL claim sought to impose on tobacco
    49
    companies a duty not to advertise in a way that could encourage minors to smoke,
    but such a duty is preempted by federal authority].)
    Moreover, in some instances, an action may not lie under the UCL because
    another statutory scheme provides the exclusive means for resolving disputes. For
    example, a claim cannot be brought under the UCL if it falls within the scope of
    the exclusive remedy provision of the workers’ compensation law and the “risks
    encompassed by the compensation bargain” — even if the claim is “ ‘collateral to
    or derivative of’ an injury compensable by the exclusive remedies of the [workers’
    compensation system].” (Charles J. Vacanti, M.D., Inc. v. State Comp. Ins. Fund
    (2001) 
    24 Cal. 4th 800
    , 811-812 (Vacanti).) We explained in Vacanti that
    “[w]here the acts are a ‘ “normal” part of the employment relationship’ [citation],
    or worker’s compensation claims process [citation], or where the motive behind
    these acts does not violate a ‘fundamental policy of this state’ [citation], then the
    cause of action is barred.” (Id., at p. 812; see 
    id. at pp.
    812-813 [the holding
    encompassed plaintiffs who were medical providers, not employees, but whose
    claim that insurers mishandled lien claims was “ ‘collateral to or derivative of’ ”
    an injury falling within the workers compensation scheme]; see also Altus
    
    Finance, supra
    , 36 Cal.4th at p. 1291 [the Attorney General may not bring a UCL
    action for restitution that “trespasses directly on the core function of the
    [Insurance] Commissioner”]; 
    id. at pp.
    1304-1305 [Insurance Commissioner has
    exclusive authority under the relevant statute to exercise power as trustee to
    protect policyholders and creditors when an insurance company is insolvent;
    irrelevant that UCL plaintiff was Attorney General rather than policy holder];
    MacKay v. Superior Court (2010) 
    188 Cal. App. 4th 1427
    , 1434, 1441-1443 [a
    UCL action will not lie to challenge an insurance rate previously approved by the
    Dept. of Insurance].)
    50
    We may draw an analogy between the present case and the workers’
    compensation scheme discussed in Vacanti. Whether alleged under the UCL or
    the CLRA, plaintiffs’ claim is that defendant injured them by representing that it
    was charging — and actually charging — reimbursement amounts on what
    plaintiffs assert are nontaxable sales. The claim depends upon the correctness of
    the allegation that, as a matter of law, and notwithstanding the presumption that
    sales are taxable unless the taxpayer demonstrated otherwise, defendant did not
    owe the state the tax because the defendant’s sales of hot coffee to go at its various
    premises were exempt from the sales tax. Before any court could enjoin Target
    from collecting reimbursement charges on such nontaxable sales in the future, or
    order defendant to refund such improperly charged reimbursement amounts to
    plaintiffs, the court hearing plaintiffs’ claims would have to decide whether the
    sales were taxable or exempt. But the tax code contemplates that the method by
    which the taxability of a sale may be challenged and determined is through an
    audit or deficiency determination made by the Board, or through a taxpayer’s
    refund claim before the Board, followed by judicial review of the Board’s
    decision.
    The taxability question lies at the center of the Board’s function and
    authority. We have seen that the sales tax law is exceedingly comprehensive and
    complex; its application to specific types of transactions is debatable in
    innumerable circumstances. The Legislature has subjected such questions to an
    administrative exhaustion requirement precisely to obtain the benefit of the
    Board’s expertise, permit it to correct mistakes, and save judicial resources. (See
    
    Preston, supra
    , 25 Cal.4th at p. 206; see also 
    Yamaha, supra
    , 19 Cal.4th at p. 7;
    Plaza Hollister Ltd. Partnership v. Co. of San Benito (1999) 
    72 Cal. App. 4th 1
    ,
    23.) Permitting plaintiffs to maintain their UCL and CLRA actions against Target
    based on a dispute over the taxability of a sale would require resolution of the
    51
    taxability question in a manner inconsistent with this system, forfeiting these
    benefits.
    As for the applicable procedures by which tax matters are resolved, it
    would be anomalous if persons not subject to the tax were in a better position than
    taxpayers to secure judicial review of the question whether a certain transaction is
    subject to the sales tax or is exempt. (See Chiatello v. City and County of San
    Francisco (2010) 
    189 Cal. App. 4th 472
    , 476, 496-497 [making a similar point in
    denying standing to a local taxpayer to challenge amendment to a payroll tax to
    which he was not subject].) Taxpayers themselves cannot circumvent the
    administrative procedures the tax code provides for ascertaining the application of
    the tax to their transactions. (§ 6932; see also § 6931.) They cannot obtain a
    declaratory judgment on such questions in advance of paying the tax, nor can they
    go to court for declaratory relief concerning the application of the law to their
    transactions without first exhausting administrative remedies by making a claim
    for refund. (§§ 6931, 6932; 
    Woosley, supra
    , 3 Cal.4th at p. 785, fn. 20; State Bd.
    of Equalization v. Superior 
    Court, supra
    , 39 Cal.3d at pp. 639-640; Pacific Gas &
    Electric 
    Co., supra
    , 27 Cal.3d at p. 280; Modern Barber Col. v. Cal. Emp. Stab.
    Com. (1948)

    suit to recover alleged overpayments as the exclusive means of judicial review of
    tax proceedings has long been unquestioned”]; 9 Witkin, Summary of Cal. 
    Law, supra
    , Taxation, § 375, pp. 548-549; but see Agnew v. State Bd. of Equalization
    (1999) 
    21 Cal. 4th 310
    , 320 [under certain circumstances not involving a claim for
    refund, a taxpayer may challenge the facial statutory or constitutional validity of a
    settled Board policy or a regulation by means of a declaratory relief action under
    Gov. Code, § 11350].)
    The tax code does not permit consumers to require the Board to ascertain
    whether excess reimbursement charges have been made. Rather, with respect to
    52
    excess reimbursement charges, section 6901.5 contemplates that it is for the Board
    to ascertain under its normal procedures whether any mistake has been made. If
    the matter is not raised through an audit or a deficiency determination, it is for the
    taxpayer to claim a refund from the Board, which may in turn require the taxpayer
    to refund excess reimbursement to consumers. Again, section 6901.5 confirms
    that binding decisions on such disputes are committed to the Board in the first
    instance, with the taxpayer as the party with standing to make a claim for a refund.
    As we have seen, under the Board’s annotations, the consumer lacks standing in
    disputes over the application of the tax law to particular transactions. (2 State Bd.
    of Equalization, Business Taxes Law 
    Guide, supra
    , Annot. No. 460.0028,
    pp. 4762-4763 [“In circumstances where the retailer has filed its returns for the
    applicable tax quarter and remitted the monies to the State, it has complied with its
    duties under the Sales and Use Tax Law as to sales tax reimbursement. Once the
    retailer has remitted the tax reimbursement to the Board, the sole legal avenue
    available for determining the proper application of tax is for the retailer to submit
    a claim for refund under section 6901 . . . et seq. The Board may only grant a tax
    refund to the person who paid the tax. If the Board were to deny the claim for
    refund, the retailer could pursue an action in court for refund of sales tax under
    section 6933. There is no provision in the law for an action on the part of a
    nontaxpayer to dispute the application of tax”].) (Italics added.)
    Plaintiffs’ claim also depends on a view of the retailer’s duties to
    consumers that may be inconsistent with the approach taken in the tax code.
    When the question whether a transaction is taxable or exempt arises between the
    retailer and the taxing entity under procedures established by the tax code, it is
    presumed that the transaction is taxable unless the taxpayer establishes to the
    contrary. (§ 6091; Lyon Metal Products, Inc. v. State Bd. of Equalization (1997)
    
    586 Cal. App. 4th 906
    , 912.) The retailer, as taxpayer, bears the burden of
    53
    maintaining records and demonstrating that the transaction is exempt from the
    sales tax. (Southern California 
    Edison, supra
    , 7 Cal.3d at p. 663; Modern Paint &
    Body Supply, Inc. v. State Bd. of Equalization (2001) 
    87 Cal. App. 4th 703
    , 707-
    708; 
    Paine, supra
    , 137 Cal.App.3d at p. 443; see also 
    Schwartz, supra
    , 31 Cal.2d
    at p. 64.) Given the taxpayer’s burden of proof, the fact that retail sales are
    presumed to be subject to the sales tax, and the fact that a retailer is not required to
    seek a refund but rather will be deemed to have waived the right to refund if a
    timely claim is not filed (§ 6905), it would not be unreasonable if the retailer’s tax
    payment to some extent erred on the side of considering sales taxable. Indeed, the
    taxpayer may recognize that it has failed to retain records adequate to carry its
    burden of establishing it is entitled to an exemption or has overpaid.
    The Board also suggests that in its view, taxpayers are not required to take
    advantage of sales tax exemptions, and owe no duty to consumers in that respect.
    The Board argues that the injunction plaintiffs seek would require a holding that
    defendant was not entitled to waive the benefit of the alleged exemption — despite
    section 6933, which provides that a taxpayer’s failure to bring a claim within the
    statutory period constitutes a waiver “of any demand against the state on account
    of alleged overpayments.” (§ 6933.)
    Other conflicts between the tax code and the consumer remedies claimed by
    plaintiffs are readily identified. Under the tax code, if the taxability question
    proceeds from administrative proceedings to court, the Board will be the opposing
    party in any ensuing legal challenge. (See § 6933; see also § 6711.) The Board
    will be present to fully and vigorously litigate its position, leading to a judgment
    that defines the law for all and is binding on the Board for the future. Plaintiffs,
    by contrast, seek a proceeding that would produce a binding interpretation of tax
    law, but in which a party considered by the Legislature to be necessary, namely
    the Board, would be absent. In addition, to permit plaintiffs’ action to determine
    54
    the taxability question in advance or separate from any claim by the taxpayer
    could produce inconsistent judgments on that point. A judgment in a quickly
    litigated consumer action could occur in advance of the Board’s resolution of the
    same question, or in advance of a judgment reviewing the Board’s determination.
    Furthermore, in the context of a refund claim filed by a taxpayer, the Board
    would be able to determine whether the state should refund excess tax to the
    taxpayer (conditioned on refund to customers) in order to avoid unjust enrichment
    of the state. In a consumer action such as plaintiffs’, by contrast, the action would
    be directed solely at the taxpayer and would not seek to require the Board to
    refund any excess amount that had been remitted to it. The Board would thereby
    lose the ability to ensure the integrity of its own tax collections.
    We also note that the tax code imposes various time limits for Board and
    taxpayer claims that differ from limitations periods for consumer claims. For
    example, taxpayers generally must seek a refund within three years after the end of
    the reporting period in which the alleged overpayment was made or six months
    after the date of a deficiency determination. (§ 6902; Cal. Code Regs., tit. 18,
    § 5231; see also § 6487 [ordinarily the Board’s notice of deficiency determination
    must be mailed within three years of the filing of the return].) A UCL action, by
    contrast, may be brought within four years after the cause of action accrued (see
    Bus. & Prof. Code, § 17208; Cortez v. Purolator Air Filtration Products Co.
    (2000) 
    23 Cal. 4th 163
    , 178-179 [UCL limitations period applies even to claims
    based on violation of statutes bearing shorter limitations periods].)
    It is evident how exceedingly numerous, as well as arcane, would be the
    disputes advancing to court for judicial resolution if consumer reimbursement
    claims turning on the taxability question could be brought under the UCL and
    CLRA. As a practical matter, if we did not view the tax code as providing the
    exclusive procedure under which a claim such as plaintiffs’ may be resolved,
    55
    independent consumer claims against retailers for restitution of reimbursement
    charges on nontaxable sales could form a huge volume of litigation over all the
    fine points of tax law as applied to millions of daily commercial transactions in
    this state. Such litigation would occur outside the system set up by the Legislature
    to develop that law, and without the benefit of the Board’s expertise or its ability
    to conserve judicial resources by correcting error by means of administrative
    proceedings. Actions of this sort could displace the Board and the procedures
    currently established by the Legislature, thereby undermining the “orderly
    administration of the tax laws.” (Decorative 
    Carpets, supra
    , 58 Cal.2d at p. 255.)
    We also observe that permitting plaintiffs’ action to go forward as currently
    framed would raise the constitutional questions identified by the Court of Appeal.
    A UCL or CLRA action requiring a court to determine the taxability of a sale
    would produce practical consequences that could threaten revenue collection and
    the ability of government to plan for expenditures. In an administrative claim or
    lawsuit brought under tax code procedures, the retailer/taxpayer necessarily will
    already have paid the tax — including an amount reflecting any reimbursement
    charges the retailer has declined to return to consumers. In a consumer action, by
    contrast, a judgment on the question of taxability could be entered in a consumer
    suit without any requirement that the tax have been paid — a result that would at
    least strain the constitutional principle that taxes should be paid first and litigated
    second in order to ensure that the state is able to plan its budget. Plaintiffs’ claim
    that they should not be required to allege whether or not the Board has received
    the disputed tax payments from the retailer because such facts are not available to
    them simply highlights the threat to the integrity of the tax system that an
    independent consumer lawsuit such as theirs presents.
    Further impact on revenue collection would follow an injunction
    prohibiting retailers from collecting the reimbursement, because the injunction
    56
    necessarily would be based upon a determination whether certain sales were
    taxable or exempt. This would affect the retailer’s (and its accountant’s) view of
    the legal question of what sales the retailer should in the future include in its
    estimate of its gross taxable income. So in the end, as the Court of Appeal
    recognized, such an injunction could indirectly reduce the flow of tax revenue in
    the future.13 It is a troubling prospect that this effect could occur totally outside
    the regulatory system established in the tax code, without any litigation between
    the state and the taxpayer concerning the latter’s duties. Again, these
    consequences present at least a potential for the conflict with article XIII, section
    32 that was envisioned by the Court of Appeal, and of course statutes should be
    interpreted to avoid potential constitutional concerns.
    The prospect of a question of tax law being settled without any litigation
    between the state and the taxpayer implicates another element of the constitutional
    provision — that is, the obligation that courts defer to the system established by
    the Legislature for ascertaining tax liability and a taxpayer’s entitlement to a
    refund. If a retailer decided to continue to pay the tax, collect the reimbursement
    the consumer considers excessive, and seek a refund according to normal tax
    code procedures, the Board in that proceeding could be faced with a final
    judgment — arising from prior consumer litigation in which it was not involved
    — purporting to determine the taxability question. In this sense, an action for a
    tax refund would be brought, or at least would be processed, not entirely “in the
    13     The sales and use tax produced 20 percent of state tax revenues in the 2012-
    2013 fiscal year. (Cal. State Controller’s Office, State Finances 101

    2014].)
    57
    manner prescribed by the Legislature.” 
    (Woosley, supra
    , 3 Cal.4th at p. 789,
    italics added.)
    In sum, the existing sales tax system is irreconcilable with these plaintiffs’
    UCL and CLRA claims.
    Plaintiffs’ claim that consumer actions such as theirs are necessary to deter
    misconduct by the retailer is unfounded, as is their claim that our decisions in
    Decorative 
    Carpets, supra
    , 
    58 Cal. 2d 252
    , and 
    Javor, supra
    , 
    12 Cal. 3d 790
    ,
    support their argument in favor of a consumer action. First, the Legislature has
    provided the methods it believes necessary to deter and punish taxpayer
    misconduct by enacting statutes authorizing the exaction of interest and the
    imposition of financial, criminal, and other penalties against taxpayers who fail to
    remit sales tax to the state. (See § 6597 [any retailer who knowingly collects sales
    tax reimbursement but fails to timely remit the amount to the Board is subject to a
    penalty of 40 percent of the amount not timely remitted]; see also §§ 6484- 6485
    [general penalties], 6512 [interest on tax deficiencies], 6514 [penalty for fraud],
    6591 [interest and penalty for late payments or nonpayments].)
    Concerns about providing a remedy so that the retailer is not unjustly
    enriched thus have been mitigated since our decisions in Decorative 
    Carpets, supra
    , 
    58 Cal. 2d 252
    , and 
    Javor, supra
    , 
    12 Cal. 3d 790
    . The Legislature has taken
    steps that diminish the need to consider a consumer remedy that is independent of
    the tax code. Section 6597, subdivision (a)(1), with its 40 percent penalty, was
    adopted in 2006. (Stats. 2006, ch. 252, § 1, p. 2167; see Sen. Com. on Rev. &
    Tax., Analysis of Sen. Bill No. 1449 (2005-2006 Reg. Sess.) for hearing on Apr.
    26, pp. 1, 2 [previously, no specific penalty applied to failure to remit the tax after
    knowing collection of sales tax reimbursement]; Sen. Rules Com., Off. of Sen.
    Floor Analyses, 3d reading analysis of Sen. Bill No. 1449 (2005-2006 Reg. Sess.)
    as amended Aug. 7, 2006, p. 2 [it was difficult for the Board to demonstrate the
    58
    mental element required under § 6484 to impose the general 25 percent penalty for
    fraud or intent to evade tax; the enactment “ ‘will enable [the Board] to impose a
    stiff, swift, and sure penalty on dishonest retailers who collect sales tax
    reimbursement from consumers, but who keep the money for themselves rather
    than remitting it to the state’ ”].)
    We note, too, that criminal penalties have been increased since Javor and
    Decorative Carpets were decided. Although tax code violations that are subject to
    criminal penalty ordinarily are misdemeanors (see §§ 7152-7153), in 1987 the
    Legislature designated as a felony those tax code violations in which the taxpayer
    intentionally evades the tax when the omitted payments amount to $25,000 or
    more a year. (§ 7153.5; see also former § 7153.5, added by Stats. 1987, ch. 1064,
    § 1, p. 3599.)
    In addition, we have seen that, with the adoption of section 6901.5 in 1982,
    the Legislature made it plainer that the retailer may not retain any amount it has
    represented to the consumer as sales tax reimbursement. Rather than simply
    saying, as under former section 6054.5, that the amount collected in error “shall
    constitute an obligation due from him [the retailer] to this State” and that “[s]uch
    obligation may be determined and collected by the Board” (former section 6054.5;
    Stats. 1961, ch. 872, § 1, p. 2289), section 6901.5 currently directly states that any
    amount collected on a nontaxable sale or in excess of the proper amount that is not
    returned to consumers “shall be remitted by that person [the taxpayer] to this
    state.” Because reimbursement charges that are not returned to customers now
    must flow to the Board in the form of tax payments, it is clear that a remedy that is
    directed at requiring the taxpayer to make a claim for refund from the Board,
    rather than one involving a direct claim by the consumer against the retailer, is the
    remedy that is consistent with the current governing statutory scheme.
    59
    Neither 
    Javor, supra
    , 
    12 Cal. 3d 790
    , nor Decorative 
    Carpets, supra
    , 
    58 Cal. 2d 252
    , contains language implying that current law — with its firmer
    identification of the retailer as the taxpayer, its safe harbor for retailers who have
    paid the state amounts they collected as reimbursement, and its penalty system —
    would require that a court approve a consumer action that would in various ways
    be inconsistent with the tax code. Rather, in those cases we warned that any
    remedy must be constrained by and not inconsistent with the tax code. We
    carefully identified an appropriate means to vindicate a consumer interest in a
    refund of a reimbursement charge without embracing procedures that were
    inconsistent with the tax code or disregarded the central function of the Board. In
    addition, the taxability question was not in dispute in those cases. The decisions
    certainly do not suggest that a question concerning the applicability of the tax code
    to a particular type of transaction should be resolved in a consumer action.
    The integrity of the tax system and avoidance of unjust enrichment,
    possibly of the retailer, but more probably of the state, in certain circumstances
    may support a Javor-type remedy for consumers. Plaintiffs, however, declined to
    pursue such a remedy, and we need not consider the exact showing required of
    consumers to demonstrate their entitlement to the Javor remedy.
    Plaintiffs argue that in a number of past cases courts have “considered the
    merits of [consumer] actions against private companies for wrongful sales tax
    reimbursement.” None of the decisions they cite, however, discuss the
    appropriateness of the UCL as a vehicle for a consumer to raise such a claim
    against a retailer/taxpayer. In Dell, Inc. v. Superior Court (2008) 
    159 Cal. App. 4th 911
    , for example, although the court decided a taxability question — whether
    service contracts included in the sale of a computer were subject to sales or use tax
    or were exempt — in the context of a UCL action brought by consumers against
    the seller of consumer goods, there was no dispute regarding, or discussion by the
    60
    appellate court concerning, the appropriateness of the UCL as a vehicle to raise
    such an issue. The same omission deprives the other decisions cited by plaintiffs
    of any weight in the present case. (Botney v. Sperry & Hutchinson Co. (1976) 
    55 Cal. App. 3d 49
    [in suit by class of consumers who had redeemed S & H Green
    stamps against the stamp issuer, issue was whether sales tax based on an average
    amount paid by retailers for the stamps was appropriate];14 Livingston Rock &
    Gravel Co. v. De 
    Salvo, supra
    , 
    136 Cal. App. 2d 156
    [a lease agreement did not
    require the lessee to indemnify the owner for sales tax the owner had paid to the
    Board].) It is well established, of course, that “ ‘cases are not authority for
    propositions not considered.’ ” (In re Marriage of Cornejo (1996) 
    13 Cal. 4th 381
    ,
    388.)
    The sales tax scheme contemplates that the question of the propriety of a
    reimbursement charge that turns on the taxability of a transaction must be resolved
    in the first instance by the Board in the context of a procedure recognized in the
    tax code and applying the safe harbor measures contained in that code.
    Accordingly, plaintiffs’ consumer action based on the assertion that defendant
    collected reimbursement on a nontaxable sale may not be maintained.15
    14     Plaintiffs’ “see also” citation to Sav-On Drugs, Inc. v. Superior Court
    (1975) 
    15 Cal. 3d 1
    is unhelpful, because the action before us in that case was a
    petition for peremptory writ challenging a trial court’s discovery order. We
    decided that the petitioner’s tax returns were privileged, but we had no occasion to
    consider the appropriateness of the underlying consumer action challenging a
    Board regulation concerning sales involving trading stamps, and contending that
    defendant seller had charged excessive “sales tax” to its customers in connection
    with such sales.
    15      We express no view on a question not presented by the complaint in this
    case, namely whether consumers may bring a UCL or CLRA claim against
    retailers for representing that they will remit, but in fact failing to remit amounts
    represented as reimbursement charges to the Board. As noted, in their

    DISSENTING OPINION BY LIU, J.
    Whether Target may charge sales tax on a cup of coffee is probably not the
    most gripping issue before the California Supreme Court this term. But this is not
    really a tax case. This is a case about the reach of consumer protection statutes
    that prohibit unfair business practices, including misrepresentations by a retailer as
    to what its customers are actually paying for. Today’s decision weakens those
    statutes by blessing an arrangement that mutually benefits retailers and the state
    treasury at the expense of everyday consumers. Because our tax laws do not
    foreclose private enforcement of consumer rights in the manner the court suggests
    (if they do at all), I respectfully dissent.
    I.
    When we go to a store like Target, we pay sales tax on many of the things
    we buy. Legally speaking, though, what we commonly call sales tax is actually
    sales tax reimbursement because the tax applies to the retailer, not the customer.
    (Rev. & Tax. Code, § 6051; all undesignated statutory references are to this code.)
    In other words, the retailer is the taxpayer responsible for paying sales tax; when a
    customer pays sales tax on a transaction, the customer is actually reimbursing the
    retailer for its sales tax liability arising from the transaction. Importantly, no law
    requires a retailer to recoup sales taxes from its customers, and no law requires
    customers to reimburse a retailer for sales taxes. “Whether a retailer may add
    sales tax reimbursement to the sales price of the tangible personal property sold at
    1
    retail to a purchaser depends solely upon the terms of the agreement of sale.”
    (Civ. Code, § 1656.1, subd. (a).) As with any sales agreement, the terms must not
    misrepresent what the purchaser is paying for.
    According to plaintiffs’ allegations, which we accept as true on demurrer,
    Target charges its customers sales tax reimbursement on all sales of hot coffee to
    go even though not all such sales are subject to sales tax. As the complaint says,
    Target “falsely and illegally represented to members of the general public that it
    had the legal right to charge the sales taxes,” thereby causing customers to pay an
    additional charge on hot coffee to go based on a misrepresentation. This
    misrepresentation, plaintiffs contend, violates the unfair competition law (UCL)
    (Bus. & Prof. Code, § 17200 et seq.) and the Consumer Legal Remedies Act
    (CLRA) (Civ. Code, § 1750 et seq.).
    Target has not sought a determination by the Board of Equalization (the
    Board) as to whether hot coffee to go is subject to sales tax. Instead, Target says it
    has paid to the Board all sales tax reimbursement collected on sales of hot coffee
    to go and that plaintiffs are statutorily and constitutionally barred from bringing
    this suit. In response, plaintiffs argue that there is no record of whether Target has
    paid to the Board the sales tax reimbursement it collected on hot coffee to go and
    that even if Target has done so, the suit may still go forward.
    One might wonder why Target would adopt such an arrangement — that is,
    charging its customers sales tax reimbursement on hot coffee to go and then
    remitting all the proceeds to the Board. At first glance, it does not appear that
    Target has unjustly enriched itself, as plaintiffs contend.
    But here it is important to note that the law governing whether a sale of hot
    coffee is subject to sales tax is remarkably complex. Section 6359 generally
    exempts from sales taxes “the sale of . . . food products for human consumption.”
    (§ 6359, subd. (a).) The term “food products” is defined to include “coffee.”
    2
    (§ 6359, subd. (b)(1)). But the statute provides that this exemption does not apply
    “[w]hen the food products are served as meals on or off the premises of the
    retailer” (§ 6359, subd. (d)(1)) or “are furnished, prepared, or served for
    consumption at tables, chairs, or counters . . . .” (§ 6359, subd. (d)(2)). Further,
    the sales tax exemption does not apply “[w]hen the food products are ordinarily
    sold for immediate consumption on or near a location at which parking facilities
    are provided primarily for the use of patrons in consuming the products purchased
    at the location, even though those products are sold on a ‘take out’ or ‘to go’ order
    and are actually packaged or wrapped and taken from the premises of the retailer.”
    (§ 6359, subd. (d)(3).) The exemption also does not apply “[w]hen the food
    products sold are furnished in a form suitable for consumption on the seller’s
    premises, and both of the following apply: [¶] (A) Over 80 percent of the seller’s
    gross receipts are from the sale of food products. [¶] (B) Over 80 percent of the
    seller’s retail sales of food products are sales subject to tax . . . .” (§ 6359,
    subd. (d)(6).) And the exemption does not apply “[w]hen the food products are
    sold as hot prepared food products,” although sales of “beverages (other than
    bouillon, consommé, or soup)” are exempt. (§ 6359, subds. (d)(7), (e).) Finally,
    California Code of Regulations, title 18, section 1603, subdivision (c)(1)(B)
    provides that the sale of hot coffee “on a ‘take-out’ or ‘to go’ order” by a seller
    that does not satisfy the “80-80” criteria described in subdivision (d)(6) of section
    6359 is not subject to sales tax.
    Thus, some sales of hot coffee are likely subject to sales tax while other
    sales are not. The key point is that sorting all this out would be quite onerous for
    Target. As the Board explains in its amicus brief, “the overhead expenses Target
    would incur in order to differentiate ‘to go’ sales from in-store sales could be quite
    large. . . . Target would have to distinguish sales of coffee where the customer
    bought the coffee and immediately left the store from those where the customer
    3
    bought the coffee but continued to shop in the same store or drank the coffee at
    tables and chairs in the coffee sales area. In addition, since the analysis must be
    made on a location-by-location basis, Target would need to conduct investigations
    in each of its California locations. [Citation.] The amount of administrative
    expense incurred to obtain such figures and maintain proper records would likely
    be passed on to Target’s customers in the form of higher prices.”
    Rather than keep track of what its customers do with each cup of hot coffee
    to go, it is far simpler and less costly for Target to collect sales tax reimbursement
    on every sale and remit those amounts to the Board. In so doing, Target gains the
    advantage of advertising its coffee at a lower price before adding to each sale a
    charge for what it represents as sales tax.
    Of course, Target is not required to take advantage of any sales tax
    exemption (see §§ 6905, 6933 [taxpayer’s failure to bring timely claim to recover
    overpayment “constitutes a waiver”]), and Target may understandably believe that
    the burden of maintaining relevant records and proving the exemption’s
    applicability to particular transactions is not worth the benefit (see maj. opn., ante,
    at pp. 22, 53–54). Moreover, it is possible that consumers end up paying less for
    hot coffee to go than if Target were to track each cup of coffee and pass the
    administrative costs on to its customers.
    But none of this speaks to whether a retailer may represent to its customers
    that it is collecting sales tax on a transaction when the transaction is not actually
    subject to sales tax. That is the unlawful business practice alleged here. For both
    Target and its customers, it may be more efficient for Target not to incur the cost
    of tracking each cup of coffee. But as the court acknowledges (maj. opn., ante, at
    p. 41, fn. 11), this efficiency need not come at expense of misleading consumers as
    to what they are paying for. Target could have avoided this lawsuit simply by
    advertising hot coffee to go at a higher (post-tax) price with a sign that says “all
    4
    prices include applicable sales tax.” Such an approach would not misinform
    customers; it would tell them that the price they are paying includes any
    applicable sales tax, with no representation as to whether sales tax was applicable
    to a particular transaction. Indeed, the Board has informally advised Target to use
    this approach to avoid future problems. But it is evident that this approach would
    eliminate the competitive advantage that Target enjoys from its current practice of
    advertising its coffee at a lower (pre-tax) price and then adding sales tax to each
    sale, whether or not each sale is actually subject to sales tax.
    II.
    The court today holds that a customer has no judicial recourse to challenge
    this arrangement because only the retailer, who is the taxpayer, can seek an
    official determination of whether sales tax is actually owed. According to the
    court, the customer’s only recourse is to politely ask the Board to consider the
    issue, even though no law requires the Board to resolve the issue upon a
    consumer’s request. The upshot is that Target, which has every reason to avoid
    administrative costs and keep its advertised prices low, will have no incentive to
    seek an official determination so long as it remits all of the sales tax
    reimbursement it collects to the Board. And the Board has little incentive to
    question whether the amount of tax revenue it receives from Target is too much.
    The customer is the only one harmed. The customer is the only one with a reason
    to compel an official determination of whether Target has misled the public by
    purporting to collect reimbursement for sales taxes that it does not actually owe.
    Today’s opinion does not really dispute that telling customers they are
    being charged for sales tax when no sales tax applies is an unlawful business
    practice within the meaning of the UCL and CLRA. Instead, the court holds that
    no consumer may invoke the UCL or CLRA to seek an adjudication of the issue
    because the tax laws do not allow it. The court’s expansive discussion of the tax
    5
    laws boils down to two claims, one specific and one general: First, section 6901.5
    provides a safe harbor for retailers who collect excess sales tax reimbursement and
    remit the excess amount to the Board. Upon reaching this safe harbor, “the
    retailer’s obligations are at an end.” (Maj. opn., ante, at p. 40.) Second, “the tax
    code contemplates that the method by which the taxability of a sale may be
    challenged and determined is through an audit or deficiency determination made
    by the Board, or through a taxpayer’s refund claim before the Board, followed by
    judicial review of the Board’s decision.” (Id. at p. 51.) Any other process, the
    court says, would undermine the orderly administration of the tax laws. (Id. at
    p. 56.) Neither claim is persuasive.
    A.
    The court acknowledges, as it must, that the UCL and CLRA provide
    “broad” protection for consumers against unfair business practices. (Maj. opn.,
    ante, at p. 48; see Cel-Tech Communications, Inc. v. Los Angeles Cellular
    Telephone Co. (1999) 
    20 Cal. 4th 163
    , 181 (Cel-Tech) [UCL’s “ ‘broad, sweeping
    language’ ” was intended “ ‘to permit tribunals to enjoin on-going wrongful
    business conduct in whatever context such activity might occur’ ” and “ ‘precisely
    to enable judicial tribunals to deal with the innumerable “ ‘new schemes which the
    fertility of man’s invention would contrive’ ” ’ ”]; Broughton v. Cigna
    Healthplans of California (1999) 
    21 Cal. 4th 1066
    , 1077 [“The CLRA was enacted
    in an attempt to alleviate social and economic problems stemming from deceptive
    business practices . . . .”]; Civ. Code, § 1760 [CLRA “shall be liberally construed
    and applied to promote its underlying purposes”].) In her amicus brief, the
    Attorney General notes that she “receives thousands of complaints each year and
    is not in a position to investigate and prosecute all of them. Legitimate actions by
    private litigants are necessary to supplement law enforcement efforts and to
    vindicate consumers’ rights.”
    6
    Our case law holds that “[w]hen specific legislation provides a ‘safe
    harbor,’ plaintiffs may not use the general unfair competition law to assault that
    harbor.” 
    (Cel-Tech, supra
    , 20 Cal.4th at p. 182.) But we have made clear that
    “[t]o forestall an action under the unfair competition law, another provision must
    actually ‘bar’ the action or clearly permit the conduct.” (Id. at p. 183.) The court
    does not contend that any provision actually bars plaintiffs’ lawsuit. Instead, it
    contends that section 6901.5 clearly permits the allegedly unlawful conduct.
    The plain text of the statute refutes the court’s thesis. Section 6901.5 says,
    in pertinent part: “When an amount represented by a person to a customer as
    constituting reimbursement for taxes due under this part is computed upon an
    amount that is not taxable or is in excess of the taxable amount and is actually paid
    by the customer to the person, the amount so paid shall be returned by the person
    to the customer upon notification by the Board of Equalization or by the customer
    that such excess has been ascertained. In the event of his or her failure or refusal
    to do so, the amount so paid, if knowingly or mistakenly computed by the person
    upon an amount that is not taxable or is in excess of the taxable amount, shall be
    remitted by that person to this state.”
    In the sales tax scheme, this language establishes that “ ‘[i]f tax
    reimbursement in excess of the tax liability on a transaction is collected and paid
    to the State, the taxpayer has no further tax liability . . . .’ ” (Maj. opn., ante, at
    p. 39.) But the fact that the retailer has no further tax liability does not mean it is
    immunized from liability under the consumer protection statutes. Remitting
    excess sales tax reimbursement to the state simply forestalls any tax dispute
    between the retailer and the Board. It does not forestall a dispute between the
    retailer and its customers over unlawful business practices. Plaintiffs in this case
    are not suing for a tax refund; they are suing to prevent and remedy
    misrepresentations that induce customers to reimburse Target for sales tax on
    7
    transactions for which no sales tax is actually owed. The fact that Target may
    have reached a safe harbor with respect to any audit or enforcement action by the
    Board does not give Target permission to tell its customers that certain charges are
    sales taxes when in fact they are not. I do not see how section 6901.5 permits,
    much less “clearly permit[s]” 
    (Cel-Tech, supra
    , 20 Cal.4th at p. 183), this conduct.
    Indeed, among the many arguments the Board makes in its amicus brief urging
    dismissal of this suit, the Board nowhere contends that section 6901.5 provides an
    all-purpose safe harbor of the sort that today’s decision invents.
    B.
    The court’s more general argument is that allowing plaintiffs’ suit to go
    forward will undermine the orderly administration of the tax laws. The court
    relies on the familiar precepts, codified in article XIII, section 32 of the California
    Constitution and related statutory provisions, that only a taxpayer can seek
    recovery of an overpayment, that a taxpayer must first pay the tax before disputing
    it, and that a taxpayer seeking a refund must first exhaust administrative remedies
    before going to court. But plaintiffs’ lawsuit does not run afoul of these precepts
    because it is not a tax refund action. Nor is it an action to compel Target to seek a
    refund or claim a tax exemption, or to compel the Board to provide a refund, or to
    prevent or enjoin the Board from collecting any tax. This is an ordinary consumer
    action that seeks to remedy a retailer’s practice of misinforming consumers as to
    the taxability of particular sales.
    Because the court cannot point to any law that actually bars this lawsuit or
    clearly permits the alleged misconduct, it must ultimately resort to considerations
    of policy. Thus, the court says that allowing this suit to go forward will lead to
    adjudication of tax questions “without the benefit of the Board’s expertise or its
    ability to conserve judicial resources by correcting error by means of
    administrative proceedings” (maj. opn., ante, at p. 56), “could produce
    8
    inconsistent judgments” between courts or between a court and the Board (id. at
    p. 55), and “could threaten revenue collection and the ability of government to
    plan for expenditures” (id. at p. 56). These concerns flow from the premise that
    the Board “would be absent” from any consumer litigation and thus will not have
    had any chance to reach its own determination on the taxability question before a
    court issues a judgment. (Id. at p. 54.)
    But there is a simple solution for this: In any civil action, a court “shall”
    join as a party a person who “claims an interest relating to the subject of the action
    and is so situated that the disposition of the action in his absence may (i) as a
    practical matter impair or impede his ability to protect that interest or (ii) leave any
    of the persons already parties subject to a substantial risk of incurring double,
    multiple, or otherwise inconsistent obligations by reason of his claimed interest.”
    (Code Civ. Proc., § 389, subd. (a).) Today’s opinion acknowledges that the Board
    is “a party considered by the Legislature to be necessary” in “a proceeding that
    would produce a binding interpretation of tax law.” (Maj. opn., ante, at p. 54.)
    Why isn’t joinder of the Board an adequate response to the concerns that the court
    has identified?
    There is no reason to think that the Board would be reluctant to participate
    as a party or that a court would be reluctant to join the Board. In this case, the
    Board has filed a lengthy amicus brief defending its prerogative to decide the
    taxability question at issue. If plaintiffs’ suit were to go forward, presumably the
    Board would not hesitate to be joined as a party. Joining the Board would not run
    afoul of the state Constitution because plaintiffs do not seek “to prevent or enjoin
    the collection of any tax.” (Cal. Const., art. XIII, § 32.) In the course of the
    proceeding, the Board would provide its determination of when hot coffee to go is
    subject to sales tax, and the court would have the benefit of the Board’s expertise
    before rendering a judgment.
    9
    Suppose the court decides that Target has overpaid its taxes. Target would
    then be required to return any overcharges to its customers and to avoid future
    misrepresentations. Going forward, Target may choose to distinguish taxable
    from nontaxable sales of hot coffee, and it may seek a refund of any excess sales
    taxes it remitted to the Board. But Target need not do so if it believes the
    administrative costs outweigh the benefits. As noted, Target can elect to keep
    paying sales tax on all sales of hot coffee to go while passing the cost on to
    consumers by charging higher prices with a sign that says “all prices include
    applicable sales tax.” The decision whether to utilize an exemption or seek a
    refund is entirely up to Target. Further, plaintiffs have not sought any remedy
    from the Board, and the burden is on Target, not the Board, to initiate the refund
    process. (§ 6091.) I do not see how such a procedure would undermine the
    orderly administration of the tax laws any more than judicial review of a Board
    decision on the same question in an audit, deficiency determination, or refund
    action.
    The court distinguishes Javor v. State Board of Equalization (1974) 
    12 Cal. 3d 790
    (Javor) on the ground that compulsory joinder of the Board in that case
    served to allow the “retailers to make refund applications to the Board” and to
    enable “the Board to respond to these applications by paying into court all sums, if
    any, due defendant retailers.” (Id. at p. 802; see maj. opn., ante, at pp. 13, 60.)
    But nothing in Javor indicates that this remedial approach is exclusive of all
    others. Today’s opinion, unlike Javor, leaves consumers who have been charged
    sales tax reimbursement on nontaxable sales with no judicial recourse at all, even
    as it makes no attempt to explain why joinder of the Board would not adequately
    protect the interests of the Board, retailers, and the public in the orderly
    administration of the tax laws.
    10
    Finally, the court says that “independent consumer claims against retailers
    for restitution of reimbursement charges on nontaxable sales could form a huge
    volume of litigation over all the fine points of tax law as applied to millions of
    daily commercial transactions in this state.” (Maj. opn., ante, at p. 56.) This
    would be true only if consumers often had cause to suspect retailers of
    misrepresenting the applicability of the sales tax to particular items. But there is
    no reason to believe this is so. Before today’s decision, no authority foreclosed
    suits like this one, yet there is no indication that such suits are common. This case
    seems unusual because some sales of hot coffee are taxable while others are not.
    Neither the court, the Board, nor Target contends that a similar ambiguity affects
    the taxability of many other items. With no evident basis for concern, the court’s
    warning of a flood of litigation is a mere makeweight.
    III.
    This case is really quite straightforward. Plaintiffs allege an unlawful
    business practice that lies squarely within the broad language and policy
    objectives of the UCL and CLRA. No statute bars this action, and no law clearly
    permits the allegedly unlawful conduct. Plaintiffs’ suit implicates a taxability
    question. But judicial resolution of the question, with the Board joined as a party,
    presents no greater threat to the orderly administration of the tax laws than judicial
    review of a Board determination addressing the same question. The lengthy
    disquisition on our tax laws in today’s opinion suggests a category error: The
    court has mistaken an ordinary consumer action that involves a tax question for a
    tax refund suit that precludes an ordinary consumer action.
    The court’s ruling, though erroneous, need not be read to broadly establish
    that a consumer action may never go forward if it involves a tax issue. This case
    implicates a rather arcane and complicated question of taxability. Future cases
    may implicate tax questions that are distinguishable from the one at issue here. In
    11
    light of California’s strong legislative policy against deceptive business practices,
    courts should hesitate to expand the hole that today’s decision carves out of our
    consumer protection statutes.
    Because of today’s ruling, we may never know when hot coffee to go is
    actually subject to sales tax because neither a retailer nor the Board has any
    incentive to resolve the issue. That in itself is no great travesty. But why should a
    retailer be allowed to misrepresent to consumers that all sales of a particular item
    are subject to sales tax when in fact they are not? A consumer who seeks her day
    in court to contest this misrepresentation is simply out of luck, while the retailer
    and the Board stay mum and mutually benefit. Nothing in the tax laws or our
    precedents authorizes such a questionable arrangement, and our robust consumer
    protection statutes are not so easily defeated.
    I respectfully dissent.
