    2          UNITED STATES V. STATE OF CALIFORNIA
    SUMMARY *
    Immigration
    In a case in which the United States sought to enjoin the
    enforcement of three laws California enacted expressly to
    protect its residents from federal immigration enforcement,
    the panel affirmed in part and reversed in part the district
    court’s denial in large part of the United States’ motion for a
    preliminary injunction.
    The United States challenged three California laws:
    AB 450, which—as relevant to this appeal—requires
    employers to alert employees before federal immigration
    inspections; AB 103, which imposes inspection
    requirements on facilities that house civil immigration
    detainees; and SB 54, which limits the cooperation between
    state and local law enforcement and federal immigration
    authorities.
    The United States sought a preliminary injunction,
    arguing that these laws violated the doctrine of
    intergovernmental immunity and the doctrine of conflict
    preemption. The district court concluded that the United
    States was unlikely to succeed on the merits of many of its
    claims, and so denied in large part the motion for a
    preliminary injunction.
    With respect to AB 450, which requires employers to
    alert employees before federal immigration inspections, the
    panel affirmed the district court’s denial of a preliminary
    * This summary constitutes no part of the opinion of the court. It

    UNITED STATES V. STATE OF CALIFORNIA                3
    injunction. The panel rejected the United States’ contention
    that the provisions are invalid under the doctrine of
    intergovernmental immunity and the doctrine of conflict
    preemption, concluding that the district court did not abuse
    its discretion when it concluded that AB 450’s employee-
    notice provisions neither burden the federal government nor
    conflict with federal activities.
    With respect to AB 103, which imposes inspection
    requirements on facilities that house civil immigration
    detainees, the panel affirmed the denial of a preliminary
    injunction as to those provisions of AB 103 that duplicate
    inspection requirements otherwise mandated under
    California law and are imposed on state and local detention
    facilities.
    However, the panel concluded that one subsection of
    AB 103—California          Government       Code       section
    12532(b)(1)(C), which requires examination of the
    circumstances surrounding the apprehension and transfer of
    immigration       detainees—discriminates      against      and
    impermissibly burdens the federal government, and so is
    unlawful under the doctrine of intergovernmental immunity.
    Specifically, the panel concluded that the district court erred
    by relying on a de minimis exception to the doctrine of
    intergovernmental immunity in analyzing this provision.
    The panel concluded that Supreme Court case law compels
    the rejection of such a de minimis exception and held that
    any economic burden that is discriminatorily imposed on the
    federal government is unlawful. The panel also concluded
    that the district court was incorrect in concluding that the
    review required by the provision appeared no more
    burdensome than reviews required under other California
    provisions. Therefore, the panel reversed the district court’s
    4        UNITED STATES V. STATE OF CALIFORNIA
    denial of a preliminary injunction as to California
    Government Code section 12532(b)(1)(C).
    With respect to SB 54, which limits the cooperation
    between state and local law enforcement and federal
    immigration authorities, the panel affirmed the district
    court’s denial of a preliminary injunction. The panel
    rejected the United States’ argument that the provisions
    violate the doctrine of obstacle preemption and the doctrine
    of intergovernmental immunity, concluding that the district
    court did not abuse its discretion when it concluded that any
    obstruction caused by SB 54 is consistent with California’s
    prerogatives under the Tenth Amendment and the
    anticommandeering rule.
    The panel also rejected the United States’ contention that
    SB 54’s information-sharing restrictions—which prohibit
    state and local law enforcement agencies from providing
    information regarding a person’s release date from
    incarceration or other personal information—conflict with
    8 U.S.C. § 1373, which provides that “a Federal, State, or
    local government entity or official may not prohibit, or in
    any way restrict, any government entity or official from
    sending to, or receiving from, [the Department of Homeland
    Security] information regarding the citizenship or
    immigration status, lawful or unlawful, of any individual.”
    Although SB 54 expressly permits the sharing of information
    about immigration status, the United States argued that
    section 1373 actually applies to more information than just
    immigration status, and hence that SB 54’s prohibition on
    sharing other information created a direct conflict. The
    panel disagreed, explaining that the language of section 1373
    is naturally understood as a reference to a person’s legal
    classification under federal law.
    UNITED STATES V. STATE OF CALIFORNIA                5
    Finally, the panel addressed California’s argument that
    the three other factors for determining whether to issue a
    preliminary injunction—irreparable harm, the balance of the
    equities, and the public interest—provide an alternative basis
    for affirming the district court’s denial of a preliminary
    injunction. Because the panel concluded that the United
    States is unlikely to succeed on the merits of its challenges
    to AB 450 and SB 54, the panel considered these factors only
    as applied to the provision of AB 103 that imposes an
    impermissible burden on the federal government. The panel
    concluded it was not prepared, in the first instance, to affirm
    the district court’s denial of a preliminary injunction as to
    this provision based on equitable considerations. However,
    the panel encouraged the district court, on remand, to
    reexamine the equitable factors in light of the evidence in the
    record.

    10       UNITED STATES V. STATE OF CALIFORNIA
    OPINION
    M. SMITH, Circuit Judge:
    Defendant-Appellee State of California (California)
    enacted three laws expressly designed to protect its residents
    from federal immigration enforcement: AB 450, which
    requires employers to alert employees before federal
    immigration inspections; AB 103, which imposes inspection
    requirements on facilities that house civil immigration
    detainees; and SB 54, which limits the cooperation between
    state and local law enforcement and federal immigration
    authorities. Plaintiff-Appellant United States of America
    (the United States) challenged these enactments under the
    Supremacy Clause and moved to enjoin their enforcement.
    The district court concluded that the United States was
    unlikely to succeed on the merits of many of its claims, and
    so denied in large part the motion for a preliminary
    injunction.
    The district court did not abuse its discretion when it
    concluded that AB 450’s employee-notice provisions neither
    burden the federal government nor conflict with federal
    activities, and that any obstruction caused by SB 54 is
    consistent with California’s prerogatives under the Tenth
    Amendment and the anticommandeering rule. We therefore
    affirm the district court’s denial of a preliminary injunction
    as to these laws. We also affirm the denial of a preliminary
    injunction as to those provisions of AB 103 that duplicate
    inspection requirements otherwise mandated under
    California law. But we conclude that one subsection of AB
    103—codified at California Government Code section
    12532(b)(1)(C)—discriminates against and impermissibly
    burdens the federal government, and so is unlawful under the
    doctrine of intergovernmental immunity. Because the
    UNITED STATES V. STATE OF CALIFORNIA               11
    district court relied on incorrect law in analyzing this
    provision, we reverse its preliminary injunction order in part.
    FACTUAL AND PROCEDURAL BACKGROUND
    I. Factual Background
    We first review the relevant federal statutory framework
    before describing the three California laws at issue in this
    case.
    A. Federal Statutory Framework
    i. The INA
    “The Government of the United States has broad,
    undoubted power over the subject of immigration and the
    status of aliens.” Arizona v. United States (Arizona II),
    
    567 U.S. 387
    , 394 (2012); see also U.S. Const. art. I, § 8,
    cl. 4 (granting Congress the power to “establish an uniform
    Rule of Naturalization”); United States v. Curtiss-Wright
    Exp. Corp., 
    299 U.S. 304
    , 315–18 (1936) (exploring the
    federal government’s inherent sovereign powers in the realm
    of foreign affairs). Congress exercises its authority to
    regulate the entry, presence, and removal of noncitizens
    through the Immigration and Nationality Act (INA) and
    other related laws, and “has specified which aliens may be
    removed from the United States and the procedures for doing
    so.” Arizona 
    II, 567 U.S. at 396
    . “A principal feature of the
    removal system is the broad discretion exercised by
    immigration officials.” 
    Id. For example,
    “an alien may be
    arrested and detained pending a decision on whether the
    alien is to be removed from the United States,” and until that
    decision, federal officials generally may either detain her or
    release her on bond. 8 U.S.C. § 1226(a). Detention is
    mandatory, however, for certain categories of noncitizens,
    12        UNITED STATES V. STATE OF CALIFORNIA
    including those who are inadmissible or removable due to
    criminal convictions. 
    Id. § 1226(c).
    “The Attorney General shall arrange for appropriate
    places of detention for aliens detained pending removal or a
    decision on removal,” which might include the “purchase or
    lease of [an] existing prison, jail, detention center, or other
    comparable facility suitable for such use.” 
    Id. § 1231(g);
    see
    also 
    id. § 1103(a)(11)
    (permitting agreements with states
    and localities “for the necessary construction, physical
    renovation, acquisition of equipment, supplies or materials
    required to establish acceptable conditions of confinement
    and detention”).       The United States notes that the
    Department of Homeland Security (DHS) “regularly uses
    nine facilities in California to house civil immigration
    detainees,” which collectively have a capacity of
    approximately 5,700 detainees. The interplay between
    federal and state authorities also manifests itself when
    noncitizens subject to removal are also the targets of state or
    local criminal enforcement. The INA requires that DHS
    remove an alien who is subject to a final removal order
    “within a period of 90 days” from “the date the alien is
    released from [state or local] detention or confinement”;
    however, it “may not remove an alien who is sentenced to
    imprisonment until the alien is released from
    imprisonment.” 
    Id. § 1231(a)(1),
    (4) (emphasis added).
    After release, federal authorities “shall detain the alien,” and
    “[u]nder no circumstance during the removal period shall the
    Attorney General release an alien who has been found
    inadmissible . . . or deportable.” 
    Id. § 1231(a)(2).
    The United States asserts that “Congress contemplated
    cooperation between federal and state officials” when it
    allowed noncitizens to complete state criminal custody
    before removal, and points to “other provisions of the INA
    UNITED STATES V. STATE OF CALIFORNIA               13
    [that] likewise reflect that expectation of collaboration.” For
    example, the federal government is required to make
    information available to state and local authorities indicating
    “whether individuals arrested . . . for aggravated felonies are
    aliens,” and to provide liaisons and computer resources in
    connection with aliens charged with aggravated felonies. 
    Id. § 1226(d)(1).
    Additionally, DHS must respond to inquiries
    from state or local officials “seeking to verify or ascertain
    the citizenship or immigration status of any individual.” 
    Id. § 1373(c).
    In turn, “a Federal, State, or local government
    entity or official may not prohibit, or in any way restrict, any
    government entity or official from sending to, or receiving
    from, [DHS] information regarding the citizenship or
    immigration status, lawful or unlawful, of any individual.”
    
    Id. § 1373(a).
    Additionally, “[f]ederal law specifies limited
    circumstances in which state officers may perform the
    functions of an immigration officer,” such as “when the
    Attorney General has granted that authority to specific
    officers in a formal agreement with a state or local
    government.” Arizona 
    II, 567 U.S. at 408
    (citing 8 U.S.C.
    §§ 1103(a)(10), 1252c, 1324(c), 1357(g)(1)).             “State
    officials can also assist the Federal Government by
    responding to requests for information about when an alien
    will be released from their custody.” 
    Id. at 410.
    ii. The IRCA
    Congress enacted the Immigration Reform and Control
    Act of 1986 (IRCA) “as a comprehensive framework for
    ‘combating the employment of illegal aliens.’” Arizona 
    II, 567 U.S. at 404
    (quoting Hoffman Plastic Compounds, Inc.
    v. NLRB, 
    535 U.S. 137
    , 147 (2002)). Under the IRCA,
    employers may not knowingly hire or employ aliens without
    proper work authorization. 8 U.S.C. § 1324a(a)(1)–(2).
    Employers in violation of the IRCA are subject to civil and,
    14        UNITED STATES V. STATE OF CALIFORNIA
    in cases of “a pattern or practice of violations,” criminal
    penalties. 
    Id. § 1324a(e)–(f).
    Although the IRCA
    does not impose federal criminal sanctions on
    the employee side . . . . some civil penalties
    are imposed instead.            With certain
    exceptions, aliens who accept unlawful
    employment are not eligible to have their
    status adjusted to that of a lawful permanent
    resident. Aliens also may be removed from
    the country for having engaged in
    unauthorized work. In addition to specifying
    these civil consequences, federal law makes
    it a crime for unauthorized workers to obtain
    employment through fraudulent means.
    Arizona 
    II, 567 U.S. at 404
    –05 (citations omitted).
    To ensure compliance with the IRCA, employers must
    verify the authorization statuses of prospective employees.
    8 U.S.C. § 1324a(a)(1)(B), (b). Verification is facilitated
    through a uniform inspection process; employers are
    required to retain documentary evidence of authorized
    employment, to which “immigration officers and
    administrative law judges [] have reasonable access.” 
    Id. § 1324a(b),
    (e)(2)(A). The information and documentation
    associated with the verification process may only be used to
    enforce the IRCA and INA, as well as for prosecution under
    certain criminal statutes. 
    Id. § 1324a(b)(5),
    (d)(2)(F)–(G).
    B. California’s Statutes
    This case centers on three laws enacted by the California
    legislature with the express goal “of protecting immigrants
    from an expected increase in federal immigration
    enforcement actions.” Hearing on AB 450 Before the
    UNITED STATES V. STATE OF CALIFORNIA                    15
    Assemb. Comm. on Judiciary, 2017–18 Sess. 1 (Cal. 2017)
    (synopsis).
    i. Immigrant Worker Protection Act (AB 450)
    AB 450 prohibits “public and private employers” from
    “provid[ing] voluntary consent to an immigration
    enforcement agent to enter any nonpublic areas of a place of
    labor,” unless “the immigration enforcement agent provides
    a judicial warrant.” Cal. Gov’t Code § 7285.1(a), (e). It
    similarly prohibits employers from “provid[ing] voluntary
    consent to an immigration enforcement agent to access,
    review, or obtain the employer’s employee records without
    a subpoena or judicial warrant.” 
    Id. § 7285.2(a)(1).
    It also
    limits employers’ ability to “reverify the employment
    eligibility of a current employee at a time or in a manner not
    required by” the IRCA. Cal. Lab. Code § 1019.2(a).
    In addition, AB 450 requires employers to “provide a
    notice to each current employee, by posting in the language
    the employer normally uses to communicate employment-
    related information to the employee, of any inspections of
    I-9 Employment Eligibility Verification forms or other
    employment records conducted by an immigration agency
    within 72 hours of receiving notice of the inspection.” 
    Id. § 90.2(a)(1).
    1    If an employer receives “the written
    immigration agency notice that provides the results of the
    inspection,” then she must provide a copy to each “employee
    identified by the immigration agency inspection results to be
    an employee who may lack work authorization” and each
    1
    AB 450 “does not require a penalty to be imposed upon an
    employer or person who fails to provide notice to an employee at the
    express and specific direction or request of the federal government.”
    Cal. Lab. Code § 90.2(c).
    16         UNITED STATES V. STATE OF CALIFORNIA
    “employee whose work authorization documents have been
    identified by the immigration agency inspection to have
    deficiencies.” 
    Id. § 90.2(b)(1)–(2).
    ii. Inspection and Review of Facilities Housing
    Federal Detainees (AB 103)
    AB 103 requires the California Attorney General to
    conduct “reviews of county, local, or private locked
    detention facilities in which noncitizens are being housed or
    detained for purposes of civil immigration proceedings in
    California.” Cal. Gov’t Code § 12532(a). 2 This includes
    “any county, local, or private locked detention facility in
    which an accompanied or unaccompanied minor is housed
    or detained on behalf of, or pursuant to a contract with, the
    federal Office of Refugee Resettlement or the United States
    Immigration and Customs Enforcement.” 
    Id. It requires
    the
    California Attorney General to review “the conditions of
    confinement,” “the standard of care and due process
    provided,” and “the circumstances around [the]
    apprehension” of civil immigration detainees, and then
    prepare “a comprehensive report outlining the findings of the
    review.” 
    Id. § 12532(b).
    To facilitate this review, the
    California Attorney General “shall be provided all necessary
    access for the observations necessary to effectuate reviews
    required pursuant to this section, including, but not limited
    to, access to detainees, officials, personnel, and records.” 
    Id. § 12532(c).
    iii. California Values Act (SB 54)
    2
    California law generally requires biennial inspections of “local
    detention facilities,” focusing on health and safety, fire suppression,
    security, and rehabilitation efforts. Cal. Penal Code § 6031.1(a).
    UNITED STATES V. STATE OF CALIFORNIA                         17
    SB 54 limits law enforcement’s “discretion to cooperate
    with immigration authorities.” 
    Id. § 7282.5(a).
    Among
    other things, it prohibits state and local law enforcement
    agencies from “[i]nquiring into an individual’s immigration
    status”; “[d]etaining an individual on the basis of a hold
    request”; “[p]roviding information regarding a person’s
    release date or” other “personal information,” such as “the
    individual’s home address or work address”; and “[a]ssisting
    immigration authorities” in certain activities.            
    Id. § 7284.6(a)(1).
    SB 54 contains some exceptions to these
    prohibitions. For example, although agencies generally
    cannot “[t]ransfer an individual to immigration authorities,”
    such an undertaking is permissible if “authorized by a
    judicial warrant or judicial probable cause determination,”
    or if the individual has been convicted of certain enumerated
    crimes. 
    Id. §§ 7282.5(a),
    7284.6(a)(4). Similarly, the
    restrictions on sharing personal information are also relaxed
    if the individual has been convicted of an enumerated crime,
    or if the information is available to the public. 
    Id. §§ 7282.5(a),
    7284.6(a)(1)(C)–(D). 3
    3
    California asserts that SB 54 was motivated by its “recogni[tion]
    that victims and witnesses of crime are less likely to come forward if
    they fear that an interaction with law enforcement will lead to their
    removal or the removal of a family member,” and that the law built upon
    prior legislative efforts. See Cal. Penal Code § 422.93 (“Whenever an
    individual who is a victim of or witness to a hate crime . . . is not charged
    with or convicted of committing any crime under state law, a peace
    officer may not detain the individual exclusively for any actual or
    suspected immigration violation or report or turn the individual over to
    federal immigration authorities.”); see also Cal. Gov’t Code § 7284.2
    (outlining the legislative findings undergirding SB 54 and reporting that
    “immigrant community members fear approaching police” and
    “[e]ntangling state and local agencies with federal immigration
    enforcement programs diverts already limited resources and blurs the
    lines of accountability between local, state, and federal governments”).
    18         UNITED STATES V. STATE OF CALIFORNIA
    II. Procedural Background
    On March 6, 2018, the United States filed this action
    against California, alleging that AB 450, AB 103, and SB 54
    are preempted and violate the Supremacy Clause. The
    United States moved to preliminarily enjoin the three laws.
    The district court granted the motion for a preliminary
    injunction in part and denied it in part. United States v.
    California (California I), 
    314 F. Supp. 3d 1077
    , 1112 (E.D.
    Cal. 2018). It agreed that the United States was likely to
    succeed on the merits as to two provisions of AB 450—
    specifically, the restriction on employers’ voluntary consent
    to immigration enforcement officers, which the court
    concluded “impermissibly discriminates against those who
    choose to deal with the Federal Government,” and AB 450’s
    reverification provision, which it determined was likely
    preempted. 
    Id. at 1096,
    1098. 4 However, the court found
    “no merit to [the United States’] Supremacy Clause claim as
    to” AB 450’s employee-notice provisions, reasoning,
    “Given IRCA’s focus on employers, the Court finds no
    indication—express or implied—that Congress intended for
    employees to be kept in the dark.” 
    Id. at 1097.
    The notice
    provisions did not “violate the intergovernmental immunity
    doctrine,” the district court continued, because “[a]n
    employer is not punished for its choice to work with the
    Federal Government, but for its failure to communicate with
    its employees.” 
    Id. As to
    AB 103, the district court found “no indication in
    the cited portions of the INA that Congress intended for
    4
    California does not appeal the partial grant of the United States’
    motion.
    UNITED STATES V. STATE OF CALIFORNIA               19
    States to have no oversight over detention facilities operating
    within their borders,” noting that
    AB 103’s review process does not purport to
    give California a role in determining whether
    an immigrant should be detained or removed
    from the country. The directive contemplates
    increased transparency and a report that may
    serve as a baseline for future state or local
    action. At this point, what that future action
    might be is subject to speculation and
    conjecture.
    
    Id. at 1091.
    It further concluded that AB 103 was not invalid
    under the doctrine of intergovernmental immunity because
    “the burden placed upon the facilities is minimal,” and “even
    if AB 103 treats federal contractors differently than the State
    treats other detention facilities,” the United States had not
    demonstrated that California “treats other facilities better
    than those contractors.” 
    Id. at 1093.
    The district court also refused to enjoin the challenged
    provisions of SB 54, finding that California’s “decision not
    to assist federal immigration enforcement in its endeavors is
    not an ‘obstacle’ to that enforcement effort” because
    “refusing to help is not the same as impeding,” and thus the
    doctrine of obstacle preemption did not render the provisions
    unlawful. 
    Id. at 1104–05.
    It also found that “Tenth
    Amendment and anticommandeering principles counsel
    against preemption,” and that 8 U.S.C. § 1373, which
    governs the exchange of “information regarding []
    immigration status,” did not change this conclusion because
    the “plain meaning of Section 1373 limits its reach to
    information strictly pertaining to immigration status (i.e.
    what one’s immigration status is) and does not include
    20       UNITED STATES V. STATE OF CALIFORNIA
    information like release dates and addresses.” 
    Id. at 1102,
    1107. The district court determined that “a Congressional
    mandate prohibiting states from restricting their law
    enforcement agencies’ involvement in immigration
    enforcement activities—apart from, perhaps, a narrowly
    drawn information sharing provision—would likely violate
    the Tenth Amendment.” 
    Id. at 1109–10.
    Subsequently, the district court ruled on California’s
    motion to dismiss, issuing an order consistent with its
    conclusions as to the preliminary injunction. United States
    v. California (California II), No. 2:18-cv-490-JAM-KJN,
    
    2018 WL 3361055
    , at *1 (E.D. Cal. July 9, 2018). This
    timely appeal followed.
    STANDARD OF REVIEW AND JURISDICTION
    We review a district court’s denial of a preliminary
    injunction for abuse of discretion. Epona v. County of
    Ventura, 
    876 F.3d 1214
    , 1219 (9th Cir. 2017). “Our review
    is limited and deferential. The district court’s interpretation
    of the underlying legal principles, however, is subject to de
    novo review and a district court abuses its discretion when it
    makes an error of law.” Sw. Voter Registration Educ.
    Project v. Shelley, 
    344 F.3d 914
    , 918 (9th Cir. 2003) (en
    banc) (per curiam). We will therefore reverse a denial of a
    preliminary injunction if the district court “based [its
    decision] on an erroneous legal standard or a clearly
    erroneous finding of fact.” Associated Press v. Otter,
    
    682 F.3d 821
    , 824 (9th Cir. 2012) (quoting Pimentel v.
    Dreyfus,

    , 1105 (9th Cir. 2012)).
    UNITED STATES V. STATE OF CALIFORNIA                         21
    We have jurisdiction over the United States’ appeal of
    the denial of its motion for a preliminary injunction pursuant
    to 28 U.S.C. § 1292. 5
    ANALYSIS
    “A plaintiff seeking a preliminary injunction must
    establish that he is likely to succeed on the merits, that he is
    likely to suffer irreparable harm in the absence of
    preliminary relief, that the balance of equities tips in his
    favor, and that an injunction is in the public interest.” Winter
    5
    The United States’ notice of appeal is directed to both the district
    court’s preliminary injunction order and its order granting in part and
    denying in part California’s motion to dismiss. Although we have
    appellate jurisdiction over appeal of the preliminary injunction order
    pursuant to 28 U.S.C. § 1292(a)(1) (conferring jurisdiction over
    “[i]nterlocutory orders of the district courts . . . granting, continuing,
    modifying, refusing or dissolving injunctions”), we do not have
    jurisdiction over an appeal of the dismissal order. Since the district court
    did not grant California’s motion to dismiss in its entirety, that order was
    not a “full adjudication of the issues” and did not “clearly evidence[] the
    judge’s intention that it be the court’s final act in the matter,” Nat’l
    Distrib. Agency v. Nationwide Mut. Ins. Co., 
    117 F.3d 432
    , 433 (9th Cir.
    1997) (quoting In re Slimick, 
    928 F.2d 304
    , 307 (9th Cir. 1990)), and
    therefore was not final pursuant to 28 U.S.C. § 1291. See Prellwitz v.
    Sisto, 
    657 F.3d 1035
    , 1038 (9th Cir. 2011) (“[T]he district court’s order
    was not final because it did not dispose of the action as to all claims
    between the parties.”). Indeed, it is quite clear that the order was not the
    court’s final act in the matter, since it subsequently granted the United
    States’ motion to stay further proceedings pending the outcome of this
    appeal. See United States v. California, No. 2:18-cv-00490-JAM-KJN,
    
    2018 WL 5310675
    , at *1 (E.D. Cal. Oct. 19, 2018).
    The district court did not certify the non-final dismissal order
    pursuant to Federal Rule of Civil Procedure 54(b) or 28 U.S.C.
    § 1292(b), and no other apparent exceptions to the finality rule exist here.
    We therefore DISMISS the appeal of the district court’s dismissal order
    for want of appellate jurisdiction.
    22       UNITED STATES V. STATE OF CALIFORNIA
    v. Nat. Res. Def. Council, Inc., 
    555 U.S. 7
    , 20 (2008). Here,
    as the United States observes, the district court’s “sole basis
    for denying injunctive relief against the California laws at
    issue in this appeal was the court’s assessment of the merits,”
    which, it further argues, “was erroneous because the district
    court adopted an unduly narrow view of two related
    doctrines, intergovernmental immunity and conflict
    preemption.”
    The doctrine of intergovernmental immunity is derived
    from the Supremacy Clause, U.S. Const., art. VI, which
    mandates that “the activities of the Federal Government are
    free from regulation by any state.” Boeing Co. v.
    Movassaghi, 
    768 F.3d 832
    , 839 (9th Cir. 2014) (quoting
    Mayo v. United States, 
    319 U.S. 441
    , 445 (1943)).
    “Accordingly, state laws are invalid if they ‘regulate[] the
    United States directly or discriminate[] against the Federal
    Government or those with whom it deals.’” 
    Id. (alterations in
    original) (quoting North Dakota v. United States, 
    495 U.S. 423
    , 435 (1990) (plurality opinion)).
    Under the doctrine of conflict preemption, “state laws
    are preempted when they conflict with federal law. This
    includes cases where ‘compliance with both federal and state
    regulations is a physical impossibility,’ and those instances
    where the challenged state law ‘stands as an obstacle to the
    accomplishment and execution of the full purposes and
    objectives of Congress.’” Arizona 
    II, 567 U.S. at 399
    (citations omitted) (first quoting Fla. Lime & Avocado
    Growers, Inc. v. Paul, 
    373 U.S. 132
    , 142–43 (1963); and
    then quoting Hines v. Davidowitz, 
    312 U.S. 52
    , 67 (1941)).
    The latter instances constitute so-called “obstacle
    preemption,” and “[t]o determine whether obstacle
    preemption exists, the Supreme Court has instructed that we
    employ our ‘judgment, to be informed by examining the
    UNITED STATES V. STATE OF CALIFORNIA               23
    federal statute as a whole and identifying its purpose and
    intended effects.’” United States v. Arizona (Arizona I),
    
    641 F.3d 339
    , 345 (9th Cir. 2011) (quoting Crosby v. Nat’l
    Foreign Trade Council, 
    530 U.S. 363
    , 373 (2000)), aff’d in
    part, rev’d in part, 
    567 U.S. 387
    (2012). The Court has
    emphasized that “[i]mplied preemption analysis does not
    justify a ‘freewheeling judicial inquiry into whether a state
    statute is in tension with federal objectives’; such an
    endeavor ‘would undercut the principle that it is Congress
    rather than the courts that preempts state law.’ . . . [A] high
    threshold must be met if a state law is to be preempted for
    conflicting with the purposes of a federal Act.” Chamber of
    Commerce of U.S. v. Whiting, 
    563 U.S. 582
    , 607 (2011)
    (quoting Gade v. Nat’l Solid Wastes Mgmt. Ass’n, 
    505 U.S. 88
    , 110–11 (1992) (Kennedy, J., concurring in part and
    concurring in the judgment)).
    “Under these principles,” the United States contends,
    “the challenged provisions of California law are invalid and
    should have been enjoined.” We consider each statute in
    turn.
    I. AB 450
    AB 450, which imposes penalties on employers based on
    their interactions with federal immigration authorities, was
    partially enjoined by the district court; specifically, its
    provisions relating to employers who provide consent to
    federal investigations or reverify the employment eligibility
    of current employees. The district court did not, however,
    enjoin the provisions of AB 450 that establish employee-
    notice requirements. The United States maintains that “these
    provisions violate the intergovernmental immunity doctrine
    and are also subject to obstacle preemption.”
    24       UNITED STATES V. STATE OF CALIFORNIA
    Congress enacted the IRCA to combat the employment
    of unauthorized noncitizens. Arizona 
    II, 567 U.S. at 404
    –
    05. Employers are required to retain documentation
    regarding employees’ work authorizations, and to make that
    documentation available for inspection by federal officers.
    8 U.S.C. § 1324a(b)(3). Such inspections must be preceded
    by “at least three business days notice.” 8 C.F.R.
    § 274a.2(b)(2)(ii). The United States notes that “[n]either
    the statute nor the regulations require any notice to
    employees before their employers’ records are inspected, or
    after an inspection is conducted.” AB 450, by contrast,
    requires two forms of notice: first, employers must inform
    their employees of upcoming inspections within 72 hours of
    receiving notice, Cal. Lab. Code § 90.2(a)(1), and second,
    employers must share any documents providing the results
    of the inspection with any employees who might lack work
    authorization, 
    id. § 90.2(b)(1)–(2).
    A. Intergovernmental Immunity
    The United States contends that “AB 450’s provisions
    impermissibly target and discriminate against federal
    immigration enforcement operations.” It reasons that “[i]f
    any other entity—such as a state or federal regulator, or a
    private entity—inspects an employer’s records, the
    employer would have no obligation under AB 450 to notify
    its employees,” and thus that AB 450 impermissibly imposes
    a “unique regime” on the federal government.
    This argument, however, extends intergovernmental
    immunity beyond its defined scope. The doctrine has been
    invoked, to give a few examples, to prevent a state from
    imposing more onerous clean-up standards on a federal
    hazardous waste site than a non-federal project, 
    Boeing, 768 F.3d at 842
    –43; to preclude cities from banning only the
    U.S. military and its agents from recruiting minors, United
    UNITED STATES V. STATE OF CALIFORNIA               25
    States v. City of Arcata, 
    629 F.3d 986
    , 988, 990–92 (9th Cir.
    2010); and to foreclose a state from taxing the lessees of
    federal property while exempting from the tax lessees of
    state property, Phillips Chem. Co. v. Dumas Indep. Sch.
    Dist., 
    361 U.S. 376
    , 381–82, 387 (1960). Those cases dealt
    with laws that directly or indirectly affected the operation of
    a federal program or contract. The situation here is
    distinguishable—AB 450 is directed at the conduct of
    employers, not the United States or its agents, and no federal
    activity is regulated. We agree with California: “The mere
    fact that those notices contain information about federal
    inspections does not convert them into a burden on those
    inspections.” Similarly, the mere fact that the actions of the
    federal government are incidentally targeted by AB 450
    does not mean that they are incidentally burdened, and while
    the latter scenario might implicate intergovernmental
    immunity, the former does not. As the district court
    correctly recognized, to rule otherwise “would stretch the
    doctrine beyond its borders.” California 
    I, 314 F. Supp. 3d at 1097
    .
    The United States argues that the proposition that
    intergovernmental immunity is only implicated when federal
    activities are obstructed “is clearly wrong, because it would
    render the intergovernmental-immunity doctrine entirely
    redundant with the obstacle-preemption doctrine, which
    separately addresses the burdensome effect of non-
    discriminatory state laws.” We disagree. The United States
    does not accurately distinguish between the doctrines of
    intergovernmental immunity and obstacle preemption.
    Reviewing the case law in which these doctrines were
    developed yields the proper distinction: simply put,
    intergovernmental immunity attaches only to state laws that
    discriminate against the federal government and burden it in
    some way. Obstacle preemption, by contrast, attaches to any
    26       UNITED STATES V. STATE OF CALIFORNIA
    state law, regardless of whether it specifically targets the
    federal government, but only if it imposes an obstructive,
    not-insignificant burden on federal activities.
    Moreover, the United States’ position that no obstruction
    is required in intergovernmental immunity cases ignores the
    origins of the doctrine and the occasions in which it has been
    applied. “The doctrine of intergovernmental immunity arose
    from the Supreme Court’s decision in M’Culloch v.
    Maryland, which established that ‘the states have no power,
    by taxation or otherwise, to retard, impede, burden, or in any
    manner control, the operations of the constitutional laws
    enacted by congress to carry into execution the powers
    vested in the general government.’” City of 
    Arcata, 629 F.3d at 991
    (emphasis added) (citation omitted) (quoting
    M’Culloch v. Maryland, 17 U.S. (4 Wheat.) 316, 436
    (1819)); see also North 
    Dakota, 495 U.S. at 437
    –38
    (plurality opinion) (“The nondiscrimination rule finds its
    reason in the principle that the States may not directly
    obstruct the activities of the Federal Government.”
    (emphasis added)); Washington v. United States, 
    460 U.S. 536
    , 544 (1983) (“The important consideration . . . is not
    whether the State differentiates in determining what entity
    shall bear the legal incidence of the tax, but whether the tax
    is discriminatory with regard to the economic burdens that
    result.” (emphasis added)); City of 
    Arcata, 629 F.3d at 991
    (applying the nondiscrimination rule to ordinances that
    “specifically target and restrict the conduct of military
    recruiters” (emphasis added)).
    Since the advent of the doctrine, intergovernmental
    immunity has attached where a state’s discrimination
    negatively affected federal activities in some way. It is not
    implicated when a state merely references or even singles
    out federal activities in an otherwise innocuous enactment.
    UNITED STATES V. STATE OF CALIFORNIA                    27
    The Supreme Court has clarified that a state “does not
    discriminate against the Federal Government and those with
    whom it deals unless it treats someone else better than it
    treats them.” 
    Washington, 460 U.S. at 544
    –45. AB 450 does
    not treat the federal government worse than anyone else;
    indeed, it does not regulate federal operations at all.
    Accordingly, the district court correctly concluded that
    AB 450’s employee-notice provisions do not violate the
    doctrine of intergovernmental immunity.
    B. Preemption
    The United States also contends that AB 450’s
    employee-notice provisions are preempted because they
    seek “to alter the manner in which the federal government
    conducts inspections, by imposing requirements that neither
    Congress nor the implementing agency saw fit to impose.”
    We disagree. The cases to which the United States cites
    concerned either the disruption of a federal relationship or
    the undermining of a federal operation. Here, there is
    indisputably a federal relationship, but it is between federal
    immigration authorities and the employers they regulate 6—
    not between employers and their employees. AB 450
    impacts the latter relationship, not the former, and imposes
    no additional or contrary obligations that undermine or
    disrupt the activities of federal immigration authorities. In
    Arizona II, the Supreme Court observed that a “[c]onflict in
    technique can be fully as disruptive to the system Congress
    erected as conflict in overt 
    policy.” 567 U.S. at 406
    6
    Cf. Buckman Co. v. Plaintiffs’ Legal Comm., 
    531 U.S. 341
    , 347
    (2001) (“[T]he relationship between a federal agency and the entity it
    regulates is inherently federal in character because the relationship
    originates from, is governed by, and terminates according to federal
    law.”).
    28       UNITED STATES V. STATE OF CALIFORNIA
    (alteration in original) (quoting Amalgamated Ass’n of St.,
    Elec. Ry. & Motor Coach Emps. of Am. v. Lockridge,
    
    403 U.S. 274
    , 287 (1971)); see also 
    Crosby, 530 U.S. at 376
    –77 (finding preempted a state law “imposing a different,
    state system” that “undermines the President’s intended
    statutory authority”). Here, by contrast, there is no “conflict
    in technique,” because federal activity is not regulated.
    AB 450’s employee-notice provisions do not permit
    employers to hire individuals without federally defined
    authorization, or impose sanctions inconsistent with federal
    law, either of which would impermissibly “frustrate[] the
    purpose of the national legislation or impair[] the efficiency
    of those agencies of the Federal government.” Nash v. Fla.

    Elmira Sav. Bank, 
    161 U.S. 275
    , 283 (1896)). But “nothing
    in IRCA (or federal immigration policy generally) demands
    that employers, site owners, or general contractors be
    absolved from” a state’s employee-protection efforts
    “whenever undocumented aliens provide labor.” Madeira v.
    Affordable Hous. Found., Inc., 
    469 F.3d 219
    , 242 (2d Cir.
    2006); see also 
    id. at 241–42
    (finding no preemption where
    “[t]here is no irreconcilable conflict between IRCA and [a
    state workplace-protection law] such that compliance with
    both the former’s prohibition on the employment of
    undocumented workers and the latter’s safe construction site
    obligation is physically impossible”). In the absence of
    irreconcilability, there is no conflict preemption, as the
    district court correctly recognized. See California I, 314 F.
    Supp. 3d at 1097.
    II. AB 103
    AB 103 authorizes the California Attorney General to
    inspect detention facilities that house civil immigration
    detainees. The United States contends that the law
    UNITED STATES V. STATE OF CALIFORNIA                        29
    “impermissibly seeks to require facilities housing federal
    immigration detainees to cooperate with broad
    investigations that examine the due process provided to
    detainees and the circumstances surrounding the detainee’s
    apprehension and transfer to the facility.” Again, it invokes
    intergovernmental immunity and obstacle preemption.
    A. Intergovernmental Immunity
    Like AB 450, AB 103 relates exclusively to federal
    conduct, as it applies only to “facilities in which noncitizens
    are being housed or detained for purposes of civil
    immigration proceedings in California.” Cal. Gov’t Code
    § 12532(a). 7 Unlike AB 450, AB 103 imposes a specialized
    burden on federal activity, as the district court recognized.
    See California 
    I, 314 F. Supp. 3d at 1093
    . That vital
    7
    To “arrange for appropriate places of detention for aliens detained
    pending removal or a decision on removal,” 8 U.S.C. § 1231(g)(1), the
    INA contemplates use of both federal facilities and nonfederal facilities
    with which the federal government contracts. See 
    id. § 1231(g)(2)
    (requiring the federal government to “consider the availability for
    purchase or lease of any existing prison, jail, detention center, or other
    comparable facility suitable for” detainee detention); 
    id. § 1103(a)(11)
    (authorizing “payments” to and “cooperative agreement[s]” with states
    and localities). For purposes of intergovernmental immunity, federal
    contractors are treated the same as the federal government itself. See
    Goodyear Atomic Corp. v. Miller, 
    486 U.S. 174
    , 181 (1988) (“[A]
    federally owned facility performing a federal function is shielded from
    direct state regulation, even though the federal function is carried out by
    a private contractor, unless Congress clearly authorizes such
    regulation.”); Gartrell Constr. Inc. v. Aubry, 
    940 F.2d 437
    , 438–41 (9th
    Cir. 1991) (holding that state licensing requirements for construction
    contractors were preempted to the extent that they applied to federal
    contractors).
    30         UNITED STATES V. STATE OF CALIFORNIA
    distinction renders the burdensome provisions of AB 103
    unlawful under the doctrine of intergovernmental immunity.
    Prior to the enactment of AB 103, California law already
    required periodic inspections of prisons and detainment
    facilities. See Cal. Penal Code § 6031.1 (mandating biennial
    inspections of “[h]ealth and safety,” “[f]ire suppression
    preplanning,”      “[s]ecurity,   rehabilitation   programs,
    recreation, treatment of persons confined in the facilities,
    and personnel training,” and visitation conditions, as well as
    the completion of subsequent reports). AB 103, however,
    does not merely replicate this inspection scheme; in addition
    to requiring “[a] review of the conditions of confinement,”
    the enactment also calls for reviews of the “standard of care
    and due process provided to” detainees, and “the
    circumstances around their apprehension and transfer to the
    facility.” Cal. Gov’t Code § 12532(b)(1). These additional
    requirements burden federal operations, and only federal
    operations. 8
    8
    The statute requires that the California Attorney General “be
    provided all necessary access for the observations necessary to effectuate
    reviews required pursuant to this section, including, but not limited to,
    access to detainees, officials, personnel, and records.” Cal. Gov’t Code
    § 12532(c). Immigration and Customs Enforcement (ICE) official
    Thomas Homan claimed that “[t]hese inspections have caused the
    facilities to expend resources otherwise necessary for ensuring the safety
    and security of the detainees. Each inspection presents a burdensome
    intrusion into facility operations and pulls scarce resources away from
    other sensitive law enforcement tasks.” Homan also attested that “the
    broad allowances made by AB 103 for the California [Attorney General]
    to perform reviews of immigration detention facilities to include wide-
    ranging access to facilities, individuals, and records, if enforced by the
    state, will conflict with ICE’s ability to comply with other federal
    information disclosure laws, regulations, and policies.”
    UNITED STATES V. STATE OF CALIFORNIA              31
    The district court addressed this burden as follows: “[The
    United States] argues the law violates [the doctrine of
    intergovernmental immunity] because it imposes a review
    scheme on facilities contracting with the federal
    government, only. This characterization is valid. However,
    the burden placed upon the facilities is minimal and [the
    United States’] evidence does not show otherwise.”
    California 
    I, 314 F. Supp. 3d at 1093
    . Instead of challenging
    the factual conclusion regarding the severity of AB 103’s
    burden, the United States questions the district court’s legal
    conclusion, contending that “the application of the
    intergovernmental immunity doctrine does not depend on
    the size of the discriminatory burden imposed. Even a tax of
    $1 imposed only on entities that contract with the federal
    government would be unlawful.” In essence, the district
    court applied a de minimis exception to the doctrine of
    intergovernmental       immunity,      concluding     that   a
    discriminatory enactment is lawful so long as the burden it
    imposes on the federal government is minimal. But the court
    cited no authority for this proposition. We must therefore
    determine whether such an exception is cognizable.
    i. De Minimis Exception
    We agree with the United States that Supreme Court case
    law compels the rejection of a de minimis exception to the
    doctrine of intergovernmental immunity.
    The recent decision in Dawson v. Steager, 
    139 S. Ct. 698
    (2019), supports this position. There, the Court suggested
    that any discriminatory burden on the federal government is
    impermissible, writing that “[s]ection 111 disallows any
    state tax that discriminates against a federal officer or
    employee.” 
    Id. at 704
    (citing 4 U.S.C. § 111). The Court
    had previously explained that the prohibition against
    discriminatory taxes in § 111 “is coextensive with the
    32         UNITED STATES V. STATE OF CALIFORNIA
    prohibition against discriminatory taxes embodied in the
    modern constitutional doctrine of intergovernmental tax
    immunity.” Davis v. Mich. Dep’t of Treasury, 
    489 U.S. 803
    ,
    813 (1989).
    The parties do not dispute that the principles of the
    intergovernmental tax immunity doctrine apply to the
    general intergovernmental immunity doctrine. See North
    
    Dakota, 495 U.S. at 434
    –39 (plurality opinion).
    Accordingly, we are not prepared to recognize a de minimis
    exception to the doctrine of intergovernmental immunity.
    Any economic burden that is discriminatorily imposed on the
    federal government is unlawful. 9 In relying on a de minimis
    exception, the district court applied incorrect law and
    therefore abused its discretion.
    ii. Burdensome Provisions
    That is not to say, however, that the United States is
    likely to succeed on the merits as to the entirety of AB 103.
    Only those provisions that impose an additional economic
    9
    We note the practical merit of this conclusion. Rejecting a de
    minimis exception permits a clearer distinction between
    intergovernmental immunity and the related—but distinct—doctrine of
    obstacle preemption. Intergovernmental immunity is implicated when
    any burden is imposed exclusively on the federal government; obstacle
    preemption is implicated when an obstructive burden is imposed,
    regardless of its discriminatory nature. Our conclusion is also consistent
    with M’Culloch, the seminal intergovernmental immunity decision.
    There, the Supreme Court was loath to undertake the “perplexing
    inquiry, so unfit for the judicial department, what degree of taxation is
    the legitimate use, and what degree may amount to the abuse of the
    power,” and opined that “[a] question of constitutional power can hardly
    be made to depend on a question of more or less.” M’Culloch, 17 U.S.
    (4 Wheat.) at 327, 430.
    UNITED STATES V. STATE OF CALIFORNIA            33
    burden exclusively on the federal government are invalid
    under the doctrine of intergovernmental immunity.
    California maintains that all of AB 103’s requirements
    duplicate preexisting inspection demands imposed on state
    and local detention facilities. It points to regulations
    requiring its Board of State and Community Corrections (the
    Board) to inspect not only compliance with general health
    and safety standards—which are included in AB 103, see
    Cal. Gov’t Code § 12532(b)(1)(A)–(B) (requiring review of
    “the conditions of confinement” and “the standard of care”
    of detainees)—but also the availability of legal reference
    materials and confidential communications with counsel.
    See Cal. Penal Code § 6031.1; Cal. Code Regs. tit. 15,
    §§ 1063–64, 1068. California argues that AB 103’s
    requirement that the California Attorney General review the
    “due process provided to” civil immigration detainees, Cal.
    Gov’t Code § 12532(b)(1)(B), is therefore duplicative, on
    the assumption that “due process” refers to “conditions of
    confinement that affect detainees’ ability to access courts—
    such as the adequacy of the facility’s law library, the
    availability of unmonitored communications with counsel,
    and the ability to send and receive mail.” See Bounds v.
    Smith, 
    430 U.S. 817
    , 828 (1977) (recognizing that “the
    fundamental constitutional right of access to the courts
    requires prison authorities to assist inmates in the
    preparation and filing of meaningful legal papers by
    providing prisoners with adequate law libraries or adequate
    assistance from persons trained in the law”); Cornett v.
    Donovan, 
    51 F.3d 894
    , 897–98 (9th Cir. 1995) (finding that
    the Bounds right is “not limited to people who are committed
    following criminal proceedings”). At oral argument,
    California maintained that its Attorney General’s
    interpretation of “due process” is indeed as limited as its
    brief suggests, and thus does not compel any additional
    34        UNITED STATES V. STATE OF CALIFORNIA
    inspection requirements beyond those applied to other state
    facilities.
    In the context of this appeal from the denial of a
    preliminary injunction, we accept California’s limited
    construction. We therefore conclude that AB 103’s due
    process provision likely does not violate the doctrine of
    intergovernmental immunity, and that the district court’s
    denial of a preliminary injunction as to this provision should
    be affirmed. We note, however, that a broader reading of the
    term “due process” might empower the California Attorney
    General to scrutinize, say, an immigration judge’s analysis,
    the results of the Board of Immigration Appeals, or other
    related court proceedings—all of which are well outside the
    purview of a state attorney general, and not duplicative of
    the inspection requirements otherwise imposed on
    California’s state and local detention facilities.
    That is not the end of our inquiry, for as the United States
    observes, California “does not even attempt to identify any
    provision of the pre-existing inspection scheme analogous to
    the unique requirement for immigration detainees that
    inspectors must examine the circumstances surrounding
    their apprehension and transfer to the facility.” See Cal.
    Gov’t Code § 12532(b)(1)(C). This is a novel requirement,
    apparently distinct from any other inspection requirements
    imposed by California law. The district court was therefore
    incorrect when it concluded that “the review appears no
    more burdensome than reviews required under California
    Penal Code §§ 6030, 6031.1.” California 
    I, 314 F. Supp. 3d at 1093
    .
    In light of this apparent factual error, and the district
    court’s erroneous reliance on a de minimis exception to the
    doctrine of intergovernmental immunity, we reverse the
    district court’s denial of a preliminary injunction as to
    UNITED STATES V. STATE OF CALIFORNIA              35
    California Government Code section 12532(b)(1)(C)—the
    provision of AB 103 requiring examination of the
    circumstances surrounding the apprehension and transfer of
    immigration detainees.
    B. Preemption
    The United States further argues that “even if AB 103’s
    inspection regime had not discriminatorily targeted facilities
    holding federal immigration detainees, it still would be
    preempted by federal law.” We disagree.
    The cases on which the United States relies involved a
    far clearer interference with federal activity than AB 103
    creates. In Leslie Miller, Inc. v. Arkansas, 
    352 U.S. 187
    ,
    189–90 (1956) (per curiam), and Gartrell Construction Inc.
    v. Aubry, 
    940 F.2d 437
    , 441 (9th Cir. 1991), states prevented
    the federal government from entering into agreements with
    its chosen contractors until the states’ own licensing
    standards were satisfied. In Tarble’s Case, the Supreme
    Court rejected a state court’s attempt to discharge a prisoner
    held “by an officer of the United States, under claim and
    color of the authority of the United States, as an enlisted
    soldier mustered into the military service of the National
    government.” 80 U.S. (13 Wall.) 397, 412 (1871). In In re
    Neagle, the Court determined that a county sheriff could not
    hold a U.S. marshal on murder charges for actions taken on
    duty. 
    135 U.S. 1
    , 62 (1890).
    These cases evinced states’ active frustration of the
    federal government’s ability to discharge its operations.
    Here, by contrast, AB 103 does not regulate whether or
    where an immigration detainee may be confined, require that
    federal detention decisions or removal proceedings conform
    to state law, or mandate that ICE contractors obtain a state
    license. The law might require some federal action to permit
    36         UNITED STATES V. STATE OF CALIFORNIA
    inspections and produce data—a burden that, as discussed
    above, implicates intergovernmental immunity—but as
    California persuasively notes, “[M]ere collection of such
    factual data does not (and cannot) disturb any federal arrest
    or detention decision.”
    In Arizona II, the Supreme Court noted that “[i]n
    preemption analysis, courts should assume that ‘the historic
    police powers of the States’ are not superseded ‘unless that
    was the clear and manifest purpose of 
    Congress.’” 567 U.S. at 400
    (quoting Rice v. Santa Fe Elevator Corp., 
    331 U.S. 218
    , 230 (1947)). The United States does not dispute that
    California possesses the general authority to ensure the
    health and welfare of inmates and detainees in facilities
    within its borders, and neither the provisions of the INA that
    permit the federal government to contract with states and
    localities for detention purposes, see 8 U.S.C.
    §§ 1103(a)(11), 1231(g), nor the contracts themselves, 10
    10
    The contracts included in the record require that immigration
    facilities conform to California’s authority. One contract—between
    DHS and the City of Holtville, California, for use of the Imperial
    Regional Detention Facility—includes a provision requiring
    “compl[iance] with all applicable ICE, federal, state and local laws,
    statutes, regulations, and codes. In the event there is more than one
    reference to a safety, health, or environment requirement . . . the most
    stringent requirement shall apply.” Another agreement between the
    Office of the Federal Detention Trustee and a private contractor,
    Corrections Corporation of America, to house ICE detainees in San
    Diego County similarly required that “[a]ll services and programs shall
    comply with . . . all applicable federal, state and local laws and
    regulations.” The district court correctly recognized these provisions,
    writing, “The Court finds no indication in the cited portions of the INA
    that Congress intended for States to have no oversight over detention
    facilities operating within their borders. Indeed, the detention facility
    contracts [California] provided to the Court expressly contemplate
    compliance with state and local law.” California 
    I, 314 F. Supp. 3d at 1091
    (citations omitted).
    UNITED STATES V. STATE OF CALIFORNIA            37
    demonstrate any intent, let alone “clear and manifest,” that
    Congress intended to supersede this authority. The district
    court was correct when it concluded, “Given the Attorney
    General’s power to conduct investigations related to state
    law enforcement—a power which [the United States]
    concedes—the Court does not find this directive in any way
    constitutes an obstacle to the federal government’s
    enforcement of its immigration laws or detention scheme.”
    California 
    I, 314 F. Supp. 3d at 1091
    –92 (citation omitted).
    III.      SB 54
    We now reach the most contentious of the three
    challenged laws, SB 54, which, the United States contends,
    “seeks to impede the enforcement of federal immigration
    laws by manipulating the overlap between state criminal
    enforcement and federal immigration enforcement.”
    A. Preemption
    The United States argues that SB 54 unlawfully obstructs
    the enforcement of federal immigration laws. It focuses on
    a provision of the law that prohibits California law
    enforcement agencies from “[t]ransfer[ring] an individual to
    immigration authorities unless authorized by a judicial
    warrant or judicial probable cause determination.” Cal.
    Gov’t Code § 7284.6(a)(4). It notes that the INA provides
    that “[o]n a warrant issued by the Attorney General, an alien
    may be arrested and detained pending a decision on whether
    the alien is to be removed from the United States.” 8 U.S.C.
    § 1226(a) (emphasis added). It therefore concludes that
    “California has no authority to demand a judicial warrant
    that Congress chose not to require. . . . By prohibiting
    transfers of custody within secure areas of local jails in the
    absence of a judicial warrant, California prevents federal
    38       UNITED STATES V. STATE OF CALIFORNIA
    officers from obtaining custody through a safe and peaceful
    transfer.”
    We have no doubt that SB 54 makes the jobs of federal
    immigration authorities more difficult. The question,
    though, is whether that constitutes a “[c]onflict in technique”
    that is impermissible under the doctrine of obstacle
    preemption. Arizona 
    II, 567 U.S. at 406
    (alteration in
    original).
    The United States relies in part on our opinion in Oregon
    Prescription Drug Monitoring Program v. DEA, 
    860 F.3d 1228
    (9th Cir. 2017), but that case is easily distinguished.
    There, a federal agency issued statutorily authorized
    subpoenas to a state agency, and the latter sought a
    declaration that it need not respond because of a state statute
    requiring “a valid court order” in all cases in which a
    subpoena is issued. 
    Id. at 1231–32,
    1236. We concluded
    that the state statute “stands as an obstacle to the full
    implementation of the [federal statute] because it ‘interferes
    with the methods by which the federal statute was designed
    to reach [its] goal.’” 
    Id. at 1236
    (second alteration in
    original) (quoting 
    Gade, 505 U.S. at 103
    (plurality opinion)).
    Here, by contrast, neither an administrative warrant issued
    by federal authorities nor any other provision of law
    identified by the United States compels any action by a state
    or local official. With the exception of § 1373(a), discussed
    below, the various statutory provisions to which the United
    States points direct federal activities, not those of state or
    local governments. See 8 U.S.C. §§ 1226, 1231.
    We cannot simply assume that Congress impliedly
    mandated that state and local governments would act in
    accordance with these statutes. Even if Congress had every
    expectation that they would, and opted not to codify its belief
    based on the presumption that states would conduct their law
    UNITED STATES V. STATE OF CALIFORNIA                         39
    enforcement activities in concert with federal immigration
    efforts, it is a state’s historic police power—not
    preemption—that we must assume, unless clearly
    superseded by federal statute. See Arizona 
    II, 567 U.S. at 400
    . 11 As California notes, “There is [] nothing in the federal
    regulatory scheme requiring States to alert federal agents
    before releasing a state or local inmate.” The Fifth Circuit
    has aptly noted that
    [f]ederal law does not suggest the intent—let
    alone a “clear and manifest” one—to prevent
    states from regulating whether their localities
    cooperate in immigration enforcement.
    Section 1357 does not require cooperation at
    all.    And the savings clause allowing
    cooperation without a 287(g) agreement
    indicates that some state and local regulation
    of cooperation is permissible.
    City of El Cenizo v. Texas, 
    890 F.3d 164
    , 178 (5th Cir. 2018)
    (citations omitted) (citing 8 U.S.C. § 1357(g)(9)–(10)). 12
    11
    A state’s ability to regulate its internal law enforcement activities
    is a quintessential police power. See United States v. Morrison, 
    529 U.S. 598
    , 618 (2000) (“[W]e can think of no better example of the police
    power, which the Founders denied the National Government and reposed
    in the States, than the suppression of violent crime and vindication of its
    victims.”).
    12
    The United States points out that City of El Cenizo “upheld a state
    enactment that merely required state and local officials to cooperate with
    requests by federal officials,” as opposed to California’s efforts “to
    disrupt the federal scheme.” But this distinction does not alter the Fifth
    Circuit’s conclusion regarding the ability of states and localities to
    regulate the extent to which they cooperate with federal immigration
    authorities.
    40        UNITED STATES V. STATE OF CALIFORNIA
    In short, SB 54 does not directly conflict with any
    obligations that the INA or other federal statutes impose on
    state or local governments, because federal law does not
    actually mandate any state action (again, with the exception
    of § 1373, discussed below).
    But that does not resolve the lingering issue of obstacle
    preemption. The United States notes that SB 54 requires
    federal officers to, “in effect, stake out a jail and seek to
    make a public arrest. . . . Arrests of aliens in public settings
    generally require five officers and present risks to the
    arresting officer and the general public.” It contends that
    “Congress did not contemplate that, as a consequence of
    letting state detention proceed first, federal officers who
    sought to detain an alien for immigration purposes would
    need to race to the front of a local detention facility and seek
    to effectuate an arrest before the alien manages to escape.”
    Compounding the problem, the United States further claims,
    are provisions of SB 54 that preclude agencies from
    providing personal information and release dates to
    immigration authorities.           See Cal. Gov’t Code
    § 7284.6(a)(1)(C)–(D). “So not only would California
    require DHS to stake out jails to detain aliens upon their
    release,” the United States continues, “but California would
    require DHS to do so indefinitely because the agency would
    not otherwise know if and when any given alien would be
    released.”
    The district court concluded that this frustration does not
    constitute obstacle preemption:
    California’s decision not to assist federal
    immigration enforcement in its endeavors is
    not an “obstacle” to that enforcement effort.
    [The United States’] argument that SB 54
    makes immigration enforcement far more
    UNITED STATES V. STATE OF CALIFORNIA                      41
    burdensome begs the question: more
    burdensome than what? The laws make
    enforcement more burdensome than it would
    be if state and local law enforcement
    provided immigration officers with their
    assistance. But refusing to help is not the
    same as impeding. If such were the rule,
    obstacle preemption could be used to
    commandeer state resources and subvert
    Tenth Amendment principles.
    California 
    I, 314 F. Supp. 3d at 1104
    . 13 We agree. Even if
    SB 54 obstructs federal immigration enforcement, the
    United States’ position that such obstruction is unlawful runs
    directly afoul of the Tenth Amendment and the
    anticommandeering rule.
    B. The Tenth Amendment and Anticommandeering
    Rule
    “The Constitution . . . ‘confers upon Congress the power
    to regulate individuals, not States.’” Murphy v. NCAA,
    
    138 S. Ct. 1461
    , 1476 (2018) (quoting New York v. United
    States, 
    505 U.S. 144
    , 166 (1992)). Under the Tenth
    Amendment and other provisions of the Constitution, “the
    Federal Government may not compel the States to

    The Seventh Circuit has conducted a similar analysis: “[T]he
    Attorney General repeatedly characterizes the issue as whether localities
    can be allowed to thwart federal law enforcement. That is a red herring.
    . . . [N]othing in this case involves any affirmative interference with
    federal law enforcement at all, nor is there any interference whatsoever
    with federal immigration authorities.” City of Chicago v. Sessions,
    
    888 F.3d 272
    , 282 (7th Cir. 2018), vacated in part on other grounds, No.
    17-2991,

    regulatory programs.” Printz v. United States, 
    521 U.S. 898
    ,
    925 (1997).
    Ultimately, we conclude that the specter of the
    anticommandeering rule distinguishes the case before us
    from the preemption cases on which the United States relies.
    Those cases concerned state laws that affirmatively
    disrupted federal operations by mandating action (or
    inaction) contrary to the status quo. 14 In each, a state statute
    14
    See Arizona 
    II, 567 U.S. at 393
    –94 (considering four provisions
    of state law, including “[t]wo [that] create new state offenses” and two
    that “give specific arrest authority and investigative duties with respect
    to certain aliens to state and local law enforcement officers”);

    Commonwealth of Massachusetts, restricting the authority of its
    agencies to purchase goods or services from companies doing business

    objectives.” (footnote omitted)); 
    Lockridge, 403 U.S. at 276
    (exploring
    “the extent to which the maintenance of a general federal law of labor
    relations combined with a centralized administrative agency to

    traditional legal processes in this field”); 
    Nash, 389 U.S. at 236

    crucial question presented here is whether a State can refuse to pay its
    unemployment insurance to persons solely because they have preferred

    of an Alien Registration Act adopted by the Commonwealth of
    Pennsylvania.”);

    (determining that “an attempt,
    by a State, to define [the] duties or control the conduct of [the] affairs [of
    national banks] is absolutely void, wherever such attempted exercise of
    authority expressly conflicts with the laws of the United States, and
    either frustrates the purpose of the national legislation or impairs the
    efficiency of these agencies of the Federal government to discharge the
    UNITED STATES V. STATE OF CALIFORNIA                         43
    affirmatively instituted a regulatory scheme that conflicted
    with federal law, either by commission (for example, by
    applying differing standards or mandating affirmative action
    irreconcilable with federal law) or omission (by demanding
    inaction that directly conflicted with federal requirements).
    The solution to avoid conflict preemption was the same:
    invalidate the state enactment. In each case, the status quo
    would return—either no future conflicting action would be
    taken, or active compliance with federal law would
    recommence—and federal activity would no longer be
    obstructed.
    Here, by contrast, invalidating SB 54 would not prevent
    obstruction of the federal government’s activities, because
    the INA does not require any particular action on the part of
    California or its political subdivisions. Federal law provides
    states and localities the option, not the requirement, of
    assisting federal immigration authorities. SB 54 simply
    makes that choice for California law enforcement agencies.
    The United States’ primary argument against SB 54 is
    that it forces federal authorities to expend greater resources
    to enforce immigration laws, but that would be the case
    regardless of SB 54, since California would still retain the
    ability to “decline to administer the federal program.” New
    
    York, 505 U.S. at 177
    . As the Supreme Court recently
    rearticulated in Murphy, under the anticommandeering rule,
    “Congress cannot issue direct orders to state 
    legislatures,” 138 S. Ct. at 1478
    , and the Court’s earlier decision in New
    duties, for the performance of which they were created”). Leslie Miller,
    Gartrell Construction, Tarble’s Case, and Neagle featured similarly
    affirmative disruptions of federal law; their specific facts are explored in
    our discussion of AB 103 and preemption.
    44         UNITED STATES V. STATE OF CALIFORNIA
    York underscored that the rule also permits a state’s refusal
    to adopt preferred federal policies. 
    See 505 U.S. at 161
    –62.
    Even in the absence of SB 54, Congress could not “impress
    into its service—and at no cost to itself—the police officers
    of the 50 States.” 
    Printz, 521 U.S. at 922
    . 15
    Federal schemes are inevitably frustrated when states opt
    not to participate in federal programs or enforcement efforts.
    But the choice of a state to refrain from participation cannot
    be invalid under the doctrine of obstacle preemption where,
    as here, it retains the right of refusal. Extending conflict or
    obstacle preemption to SB 54 would, in effect, “dictate[]
    what a state legislature may and may not do,” 
    Murphy, 138 S. Ct. at 1478
    , because it would imply that a state’s
    otherwise lawful decision not to assist federal authorities is
    made unlawful when it is codified as state law.
    We also find no constitutional infirmity in the specific
    provisions of SB 54 that govern the exchange of information
    with federal immigration authorities. See Cal. Gov’t Code
    § 7284.6(a)(1)(C)–(D)      (prohibiting   California    law
    enforcement agencies from “[p]roviding information
    regarding a person’s release date or responding to requests
    for notification by providing release dates or other
    information unless that information is available to the
    15
    The United States suggests that these principles do not extend here
    because “both sovereigns [are] regulat[ing] private individuals,” and the
    Supreme Court has held that it “is incorrect” to “assume that the Tenth
    Amendment limits congressional power to pre-empt or displace state
    regulation of private activities affecting interstate commerce.” Hodel v.
    Va. Surface Mining & Reclamation Ass’n, 
    452 U.S. 264
    , 289–90 (1981).
    But although the INA and SB 54 both implicate noncitizens—private
    actors—SB 54 governs how California and its localities can interact with
    the federal government, not the activities of private individuals, and so
    Hodel is inapposite.
    UNITED STATES V. STATE OF CALIFORNIA              45
    public,” and “[p]roviding personal information . . . about an
    individual, including, but not limited to, the individual’s
    home address or work address unless that information is
    available to the public”). These two subparts only concern
    the exchange of information, and the Supreme Court has
    implied the existence of a Tenth Amendment exception for
    reporting requirements. See 
    Printz, 521 U.S. at 917
    –18
    (distinguishing between federal statutes that “require only
    the provision of information to the Federal Government” and
    those that “force[ the] participation of the States’ executive
    in the actual administration of a federal program”).
    The United States relies on Reno v. Condon, which
    upheld against Tenth Amendment attack a federal statute
    that “regulate[d] the disclosure and resale of personal
    information contained in the records of state DMVs”
    because it did “not require the States in their sovereign
    capacity to regulate their own citizens” and instead
    “regulate[d] the States as the owners of data bases.”
    
    528 U.S. 141
    , 143, 151 (2000). But the Supreme Court
    recently explained,
    The anticommandeering doctrine does not
    apply when Congress evenhandedly
    regulates an activity in which both States and
    private actors engage.
    That principle formed the basis for the
    Court’s decision in Reno v. Condon, which
    concerned a federal law restricting the
    disclosure and dissemination of personal
    information provided in applications for
    driver’s licenses. The law applied equally to
    state and private actors. It did not regulate
    46       UNITED STATES V. STATE OF CALIFORNIA
    the States’ sovereign authority to “regulate
    their own citizens.”
    
    Murphy, 138 S. Ct. at 1478
    –79 (citation omitted) (quoting
    
    Reno, 528 U.S. at 151
    ). Here, by contrast, it is the state’s
    responsibility to help enforce federal law, and not conduct
    engaged in by both state and private actors, that is at issue.
    We therefore conclude that Murphy’s reading of Reno
    suggests that the latter is not applicable here.
    SB 54 may well frustrate the federal government’s
    immigration enforcement efforts. However, whatever the
    wisdom of the underlying policy adopted by California, that
    frustration is permissible, because California has the right,
    pursuant to the anticommandeering rule, to refrain from
    assisting with federal efforts. The United States stresses
    that, in crafting the INA, Congress expected cooperation
    between states and federal immigration authorities. That is
    likely the case. But when questions of federalism are
    involved, we must distinguish between expectations and
    requirements. In this context, the federal government was
    free to expect as much as it wanted, but it could not require
    California’s cooperation without running afoul of the Tenth
    Amendment.
    C. Intergovernmental Immunity
    The Government also argues that SB 54 violates the
    doctrine of intergovernmental immunity.
    The district court correctly rejected that argument. See
    California 
    I, 314 F. Supp. 3d at 1110
    . In North Dakota, the
    Supreme Court endorsed “a functional approach to claims of
    governmental immunity, accommodating of the full range of
    each sovereign’s legislative authority and respectful of the
    primary role of Congress in resolving conflicts between the
    UNITED STATES V. STATE OF CALIFORNIA             47
    National and State 
    Governments.” 495 U.S. at 435
    (plurality
    opinion). A finding that SB 54 violates the doctrine of
    intergovernmental immunity would imply that California
    cannot choose to discriminate against federal immigration
    authorities by refusing to assist their enforcement efforts—a
    result that would be inconsistent with the Tenth Amendment
    and the anticommandeering rule.
    D. Section 1373
    Lastly, the United States contends that 8 U.S.C. § 1373
    directly prohibits SB 54’s information-sharing restrictions.
    Section 1373 provides that “a Federal, State, or local
    government entity or official may not prohibit, or in any way
    restrict, any government entity or official from sending to,
    or receiving from, [DHS] information regarding the
    citizenship or immigration status, lawful or unlawful, of any
    individual.” 8 U.S.C. § 1373(a). SB 54, in turn, expressly
    permits the sharing of such information, and so does not
    appear to conflict with § 1373. See Cal. Gov’t Code
    § 7284.6(e) (“This section does not prohibit or restrict any
    government entity or official from sending to, or receiving
    from, federal immigration authorities, information regarding
    the citizenship or immigration status, lawful or unlawful, of
    an individual . . . pursuant to Section[] 1373.”). But the
    United States argues that § 1373 actually applies to more
    information than just immigration status, and hence that
    SB 54’s prohibition on sharing other information creates a
    direct conflict.
    We disagree. Although the United States contends that
    “whether a given alien may actually be removed or detained
    by federal immigration authorities is, at a minimum,
    information regarding that alien’s immigration status,” the
    phrase “information regarding the citizenship or
    48         UNITED STATES V. STATE OF CALIFORNIA
    immigration status, lawful or unlawful, of any individual” is
    naturally understood as a reference to a person’s legal
    classification under federal law, as the district court
    concluded. See California 
    I, 314 F. Supp. 3d at 1102
    (“[T]he
    plain meaning of Section 1373 limits its reach to information
    strictly pertaining to immigration status (i.e. what one’s
    immigration status is) and does not include information like
    release dates and addresses.”). 16 Phrases like “regarding”
    may generally have “a broadening effect, ensuring that the
    scope of a provision covers not only its subject but also
    matters relating to that subject,” Lamar, Archer & Cofrin,
    LLP v. Appling, 
    138 S. Ct. 1752
    , 1759–60 (2018), but if the
    term “regarding” were “taken to extend to the furthest stretch
    of its indeterminacy, then for all practical purposes pre-
    16
    This is consistent with our decision in Steinle v. City and County
    of San Francisco, in which we determined that “[t]he statutory text [of
    § 1373(a)] does not include release-date information. It includes only
    ‘information regarding’ ‘immigration status,’ and nothing in [§ 1373(a)]
    addresses information concerning an inmate’s release date.” No.
    17-16283, slip op. at 16 (9th Cir. Mar. 25, 2019). Several district courts
    have reached similar conclusions regarding § 1373’s circumscribed
    scope. See, e.g., City and County of San Francisco v. Sessions, 349 F.
    Supp. 3d 924, 968 (N.D. Cal. 2018) (“Given my interpretation of Section
    1373, limiting it to information relevant to citizenship or immigration
    status not including release date information, it is clear [SB 54] complies
    with Section 1373.”), appeal docketed, No. 18-17308 (9th Cir. Dec. 4,
    2018); City of Philadelphia v. Sessions, 
    309 F. Supp. 3d 289
    , 333 (E.D.
    Pa. 2018) (“The phrase ‘citizenship or immigration status,’ plainly
    means an individual’s category of presence in the United States—e.g.,
    undocumented, refugee, lawful permanent resident, U.S. citizen, etc.—
    and whether or not an individual is a U.S. citizen, and if not, of what
    country. The phrase ‘information regarding’ includes only information
    relevant to that inquiry. When an individual will be released from a
    particular City facility, cannot be considered ‘information regarding’ his
    immigration status.”), aff’d in part, vacated in part on other grounds sub
    nom. City of Philadelphia v. Attorney Gen., 
    916 F.3d 276
    (3d Cir. 2019).

    emption would never run its course, for ‘[r]eally,
    universally, relations stop nowhere.’” N.Y. State Conference
    of Blue Cross & Blue Shield Plans v. Travelers Ins. Co.,
    
    514 U.S. 645
    , 655 (1995) (alteration in original) (quoting H.
    James, Roderick Hudson xli (New York ed., World’s
    Classics 1980)). 17
    Congress has used more expansive phrases in other
    provisions of Title 8 when intending to reach broader swaths
    of information. See, e.g., 8 U.S.C. § 1360(a) (mandating the
    inclusion of “such other relevant information as the Attorney
    General shall require as an aid” to the creation of a central
    index of noncitizens entering the country); 
    id. § 1360(b)
    (“Any information in any records kept by any department or
    agency of the Government as to the identity and location of
    aliens in the United States shall be made available to the
    Service upon request.”). The United States claims that
    § 1373(c) demonstrates the extensive reach of § 1373(a), as
    unlike the latter, the former does not use the term
    “regarding” but instead refers simply and explicitly to “the
    citizenship or immigration status of any individual.” 
    Id. § 1373(c).
    But the fact that subpart (c) only concerns itself
    with immigration status suggests, given § 1373’s focus on
    reciprocal communication between states and the federal
    government, that immigration status is the extent of
    subpart (a)’s reach as well. 18
    17
    Indeed, the range of facts that might have some connection to
    federal removability or detention decisions is extraordinarily broad. See,
    e.g., 8 U.S.C. § 1182 (listing various admissibility considerations,
    including vaccination history, education, financial resources, and
    membership in “the Communist or any other totalitarian party”).
    18
    We note that a congressional report concerning a statute with
    similar language to § 1373 indicated that it “provides that no State or
    50         UNITED STATES V. STATE OF CALIFORNIA
    The United States also relies heavily on an Information
    Bulletin issued by the California Department of Justice in
    June 2014, which read in part that “law enforcement officials
    may provide information to ICE, including notification of
    the date that an individual will be released, as requested on
    an immigration detainer form. Federal law provides that
    state and local governments may not be prohibited from
    providing information to or receiving information from
    ICE.” The United States contends that California’s “limited
    view of the scope of [§ 1373] contradicts the longstanding
    views . . . of the California Attorney General.” But the
    Information Bulletin attempted to summarize both federal
    law and California’s then-governing TRUST Act, not the
    laws at issue today. And at any rate, the previous
    conclusions of the California Attorney General do not
    change the plain text and meaning of § 1373; that the
    California Department of Justice might have been incorrect
    then does not mean that its revised interpretation is incorrect
    now.
    In summation, the district court correctly concluded that
    “Section 1373 and the information sharing provisions of SB
    local government entity shall prohibit, or in any way restrict, any entity
    or official from sending to or receiving from the [federal government]
    information regarding the immigration status of an alien or the presence,
    whereabouts, or activities of illegal aliens.” H.R. Rep. No. 104-725, at
    383 (1996) (Conf. Rep.), as reprinted in 1996 U.S.C.C.A.N. 2649, 2771.
    But the fact that the report distinguished between the two categories—
    “information regarding the immigration status of an alien or the
    presence, whereabouts, or activities”—suggests that “information
    regarding the immigration status” does not include “the presence,
    whereabouts, or activities” of noncitizens. And in any event,
    “Congress’s ‘authoritative statement is the statutory text, not the
    legislative history.’”

    IV.      Winter Factors
    California argues that the three other Winter factors—
    irreparable harm, the balance of the equities, and the public
    
    interest, 555 U.S. at 20
    —provide an alternative basis for
    affirming the district court’s denial of a preliminary
    injunction. See Big Country Foods, Inc. v. Bd. of Educ.,
    
    868 F.2d 1085
    , 1088 (9th Cir. 1989) (concluding that a
    district court’s denial of a motion for a preliminary
    injunction “may [be] affirm[ed] on any ground supported by
    the record”). Because we agree with the district court that
    the United States is unlikely to succeed on the merits of its
    challenges to AB 450’s employee-notice provisions and
    SB 54, we consider these factors only as applied to the
    provision of AB 103 that imposes an impermissible burden
    on the federal government.
    In granting the United States’ motion to enjoin the two
    invalidated provisions of AB 450, the district court
    “presume[d] that [the United States] will suffer irreparable
    harm based on the constitutional violations.” California 
    I, 314 F. Supp. 3d at 1112
    . This conclusion was consistent
    with our previous recognition that preventing a violation of

    Because we agree with the district court’s conclusion, we need not
    address whether § 1373 is itself unlawful, though we note that various
    district courts have questioned its constitutionality. See, e.g., City and
    County of San Francisco v. Sessions, 
    349 F. Supp. 3d 924
    , 949–53 (N.D.
    Cal. 2018), appeal docketed, No. 18-17308 (9th Cir. Dec. 4, 2018); City
    of Chicago v. Sessions, 
    321 F. Supp. 3d 855
    , 873 (N.D. Ill. 2018); City
    of Philadelphia v. Sessions, 
    309 F. Supp. 3d 289
    , 329–31 (E.D. Pa.
    2018), aff’d in part, vacated in part on other grounds sub nom. City of
    Philadelphia v. Attorney Gen., 
    916 F.3d 276
    (3d Cir. 2019).
    52        UNITED STATES V. STATE OF CALIFORNIA
    the Supremacy Clause serves the public interest. See, e.g.,
    Arizona 
    I, 641 F.3d at 366
    (“We have found that ‘it is clear
    that it would not be equitable or in the public’s interest to
    allow the state . . . to violate the requirements of federal law,
    especially when there are no adequate remedies
    available. . . . In such circumstances, the interest of
    preserving the Supremacy Clause is paramount.’”
    (alterations in original) (quoting Cal. Pharmacists Ass’n v.
    Maxwell-Jolly, 
    563 F.3d 847
    , 852–53 (9th Cir. 2009))); Am.
    Trucking Ass’ns v. City of Los Angeles, 
    559 F.3d 1046
    ,
    1059–60 (9th Cir. 2009) (determining that “the balance of
    equities and the public interest [] weigh in favor of a
    preliminary injunction” against a likely preempted
    ordinance).
    Nevertheless, California argues that “[t]he balance of
    equities and public interest weigh strongly against enjoining
    [its] laws during the pendency of litigation” because “a
    preliminary injunction here would lead to significant,
    concrete harm to the public.” At the district court, California
    claimed that “the Legislature passed AB 103 in reaction to
    growing concerns of egregious conditions in facilities
    housing civil detainees,” California 
    I, 314 F. Supp. 3d at 1090
    –91—a conclusion supported in detail by amici curiae,
    including the National Health Law Program and the
    Immigrant Legal Resource Center. Moreover, we note that
    California retains an historic—and, since the federal
    government’s contracts with immigration detainee facilities
    explicitly contemplate the application of state regulations,
    undisputed—authority to regulate the conditions of
    detainees housed within its borders. By contrast, other than
    relying on general pronouncements that a Supremacy Clause
    violation alone constitutes sufficient harm to warrant an
    injunction, the United States did not present compelling
    evidence that AB 103 inspections conducted by the
    UNITED STATES V. STATE OF CALIFORNIA                     53
    California Attorney General harmed facilities’ detention
    operations. Rather, the only evidence of AB 103’s
    burdensome effect is conclusory assertions made by a DHS
    official in a declaration and deposition. 20 Neither he nor the
    United States provided any indication, even an estimate, of
    the actual costs imposed by AB 103 or the number of ICE
    officers forced to assist in the extra inspection efforts, or any
    quantification whatsoever of the enactment’s burden. The
    United States’ complaint in this action did not even plead
    that the statute imposes an economic or operational burden
    on DHS or anyone else.
    We are not prepared, in the first instance, to affirm the
    district court’s denial of a preliminary injunction as to
    20
    The relevant deposition transcript reads as follows:
    [I]t’s going to require yet another inspection that we
    think is unnecessary, because these are federal
    contracts, these are federal prisoners detained under
    federal authority. We have our own set of standards.
    We certainly don’t believe there should be any
    inspections to talk about due process of people that are
    in federal custody, under federal authority, conditions
    of confinement when we have our own set of standards
    which is much higher than most states.
    So there’s this general feeling that this is—it’s
    burdensome, that they’re going to be required to pull
    resources to do these inspections, when we have
    numerous inspections already at these facilities from
    various different components.
    So again, it’s—it’s talk of burdensomeness—right?—
    extra work, pulling people from their duties to host
    these things and gather documents and paperwork and
    making people available for interviews and so forth.
    54         UNITED STATES V. STATE OF CALIFORNIA
    AB 103’s burdensome provision based on these
    considerations. However, on remand, we encourage the
    district court to reexamine the equitable Winter factors in
    light of the evidence in the record.
    CONCLUSION
    We conclude that the district court correctly determined
    that the United States was unlikely to succeed on the merits
    of its challenges to AB 450’s employee-notice provisions
    and SB 54, and therefore AFFIRM its denial of a preliminary
    injunction as to these enactments. We also AFFIRM the
    denial as to those provisions of AB 103 that duplicate
    preexisting inspection requirements. But because we
    conclude      that     California     Government       Code
    section 12532(b)(1)(C) both discriminates against and
    impermissibly burdens the federal government, we
    REVERSE the district court’s denial of the United States’
    motion as to this provision and REMAND for further
    proceedings consistent with this opinion.21
    21
    Finally, we grant the State of Michigan’s motion to withdraw from
    an amicus brief in support of the United States.
