    ____________________________________)                      Super. Ct. No. 91694B
    People convicted of noncapital murder and certain other criminal offenses
    in California serve indeterminate sentences that run from a minimum number of
    years to life, making release possible before the end of their life. The Board of
    Parole Hearings (the Board) decides, subject to relevant statutory provisions and
    review by the Governor, whether such prisoners are suitable for release. This case
    concerns the interaction of those statutory provisions with a settlement agreement
    arising from litigation about the Board’s procedures. While serving an
    indeterminate prison term, Roy Butler filed a petition for writ of habeas corpus on
    December 12, 2012, alleging in part that the Board had a responsibility to avoid
    parole determinations leading to grossly disproportionate prison terms. In 2013,
    petitioner Roy Butler and respondent, the Board, agreed to a settlement requiring
    the Board to calculate the “base terms” of an inmate serving an indeterminate
    sentence for use at the inmate’s initial parole hearing. At the time of the
    settlement agreement, “base terms” governed the earliest possible release date for
    inmates serving indeterminate sentences. Since then, changes to California’s
    1
    criminal justice system have altered the relevant statutory landscape, such that
    “base terms” no longer govern the release date of inmates subject to indeterminate
    sentences.
    The question before us is whether those statutory developments warrant
    modification of the settlement order to relieve the Board of any separate obligation
    to calculate “base terms” under the agreement. The Court of Appeal concluded
    the answer was no, so the settlement order could remain in force despite the
    statutory changes. We disagree. The settlement agreement was premised on the
    idea that “base terms” played some role –– defined by statute –– in determining
    release dates for those sentenced to indeterminate terms. Given this premise, the
    elimination of “base term” calculations from any such role is a sufficiently
    material change that it not only justifies — but in this case, requires —
    modification of the settlement by the Court of Appeal.
    The Court of Appeal also concluded that specific “base term” calculations
    were necessary to assure life prisoners would not suffer constitutionally excessive
    punishment. Here too, we differ with the appellate court. Base term calculations
    no longer play a role in the public safety assessments undertaken by the Board to
    determine the release dates for inmates sentenced to indeterminate terms, and are
    not designed or obviously well-suited as a tool for avoiding unconstitutionally
    long terms of incarceration. And, at least to some extent, these inmates are
    protected against disproportionate punishment through other means, such as
    provisions ending indeterminate sentences when individuals have served the
    statutory minimum term and have been found suitable for release. In light of the
    state’s current sentencing regime and the existence of parole procedures focusing
    on public safety determinations, the Board is not constitutionally required to
    continue calculating base terms as required in the settlement order. Accordingly,
    we reverse the Court of Appeal.
    2
    I.
    Petitioner Roy Butler was convicted of second degree murder in 1988.
    What Butler told detectives at the time of his arrest is that he and acquaintance
    Lanzester Hymes decided to attack Richard Davis because Davis had been abusing
    his girlfriend Jane Woods, a friend of Butler’s. On September 28, 1987, Butler
    and Hymes armed themselves with knives and went to the apartment that Davis,
    Hymes, and Woods shared. According to Butler, he was hiding inside the
    bathroom when Hymes fatally stabbed Davis. After Butler pleaded guilty, he
    received a sentence of 15 years to life. Butler became eligible for parole in 1997,
    but the parole authority denied his application for parole at that hearing and at
    several subsequent hearings. After the Board denied his application at a hearing in
    February 2012, Butler filed a petition for writ of habeas corpus, which led to the
    case before us.
    Prior to 1977, California used an “indeterminate” sentencing regime for the
    vast majority of felonies. (In re Dannenberg (2005) 
    34 Cal. 4th 1061
    , 1077
    (Dannenberg).) Under this system, courts “imposed a statutory sentence
    expressed as a range between a minimum and maximum period of confinement —
    often life imprisonment — the offender must serve.” (Ibid.) The state agency in
    charge of parole (then called the Adult Authority) had exclusive control over the
    period of incarceration the inmate actually served, so inmates had no idea when
    they would be released. (Id. at pp. 1077, 1089.)
    The state largely abandoned this system when it adopted a mostly
    “determinate” sentencing regime in 1976. 
    (Dannenberg, supra
    , 34 Cal.4th at p.
    1078.) Now, most felonies are subject to defined terms of confinement. But
    certain serious offenses, including noncapital murder, remain subject to
    3
    indeterminate sentences. (Ibid.)1 The sentence of 15 years to life Butler received
    in 1988 is an example of this type of punishment. For inmates serving
    indeterminate sentences, the parole authority (now called the Board of Parole
    Hearings) continues to determine the end of their period of incarceration via a
    determination that the inmate is suitable for parole. (See generally Pen. Code,
    § 3041.) 2 The standard for parole suitability is whether the inmate “will pose an
    unreasonable risk of danger to society if released from prison.” (Cal. Code Regs.,
    tit. 15, § 2281, subd. (a).)
    When this action commenced, a previous version of section 3041 governed
    the Board’s authority to set release dates for indeterminately-sentenced offenders.
    (Former § 3041; see also 
    Dannenberg, supra
    , 34 Cal.4th at pp. 1078-1079
    [describing this version of the statute].) Subdivision (a) of that statute directed the
    Board to set parolees’ release dates “in a manner that will provide uniform terms
    for offenses of similar gravity and magnitude in respect to their threat to the
    public.” (Former § 3041, subd. (a).) The statute further directed the Board, when
    setting release dates, to “consider the number of victims of the crime . . . and other
    factors in mitigation or aggravation of the crime.” (Ibid.)
    To implement this duty, the Board adopted regulations for each
    indeterminate sentence offense. These regulations expressly rely on and reference
    section 3041 as enabling authority. (See, e.g., Cal. Code Regs., tit. 15, §§ 2280
    [listing section 3041 as a statutory reference], 2400 [“This article implements
    1      Indeterminate sentences of life imprisonment are also authorized for some
    felonies less serious than murder under, for example, the Three Strikes Law. (See
    Pen. Code, §§ 667.5, subd. (e)(2)(A), 1170.12, subd. (c)(2)(A); see also, e.g., 
    id., §12022.53, subd.
    (d) [25 years-to-life enhancement for causing great bodily injury
    or death by discharge of firearm in course of certain felonies].)
    2        All subsequent statutory citations are to the Penal Code, unless otherwise
    noted.
    4
    Penal Code section 3041”].) One such set of regulations applies to noncapital
    murder committed on or after November 8, 1978. (Id., § 2400 et seq.;
    
    Dannenberg, supra
    , 34 Cal.4th at pp. 1078-1079.) Under the regulations, the
    Board is required to “set a base term for each life prisoner who is found suitable
    for parole.” (Cal. Code Regs., tit. 15, § 2403, subd. (a).) In accordance with the
    regulations, the Board must determine that an inmate is suitable for parole before
    setting that inmate’s base term. (Id., § 2402, subd. (a) [“The panel shall first
    determine whether the life prisoner is suitable for release on parole”]; see also
    
    Dannenberg, supra
    , 34 Cal.4th at pp. 1079-1080.)
    A base term is calculated using matrices that appear in said regulations.
    For murder, the matrix’s horizontal axis presents general descriptions of the cause
    of the victim’s death.3 The vertical axis lists possible descriptions of the
    relationship between the inmate and victim.4 The first step in calculating the base
    term is to determine which intersection of the horizontal and vertical axes is “most
    closely related to the circumstances of the crime.” (Cal. Code Regs., tit. 15,
    § 2403, subd. (a).) Each intersection then lists three alternative sentences — a
    lower, middle, and upper base term. For example, a second degree murder
    committed after November 8, 1978, through a “Direct” mechanism and against a
    victim with whom the inmate had a “Prior Relationship” would yield base term
    alternatives of 17, 18, or 19 years. (Id., § 2403, subd. (c).) The Board’s
    3     For example, the categories on the horizontal axis of the matrix for second
    degree murders committed after November 8, 1978, range from “Indirect” (e.g.,
    “shock producing heart attack”) to “Direct or Victim Contribution” (e.g., “[d]eath
    was almost immediate”) to “Severe Trauma” (e.g., “beating, clubbing”). (Cal.
    Code Regs., tit. 15, § 2403, subd. (c).)
    4      Here, the categories for second degree murder committed after November
    8, 1978, range from “Participating Victim” (e.g., “[v]ictim was accomplice”) to
    “Prior Relationship” to “No Prior Relationship.” (Cal. Code Regs., tit. 15,
    § 2403, subd. (c).)
    5
    regulations require it to select the middle term unless it finds circumstances in
    mitigation or aggravation (as defined elsewhere in the regulations). (Id., § 2403,
    subd. (a).) A finding that mitigating circumstances exist leads to the selection of
    the lower base term, while a finding of aggravating circumstances leads to the
    selection of the upper base term. (Id., §§ 2404, subd. (a), 2405, subd. (a).) The
    Board then modifies an inmate’s base term for any enhancements related to the
    offense (such as use of a firearm), leading to the inmate’s so-called “adjusted base
    term.” (Id., § 2406.)
    Under this version of the regulatory scheme, the Board begins its
    assessment of an inmate’s earliest possible release date by calculating his or her
    adjusted base term. These regulations allow the Board to then postpone the
    release date if the inmate has other convictions (Cal. Code Regs., tit. 15, §§ 2407-
    2409) or to advance it for any postconviction credits the inmate has received. (Id.,
    § 2410.) It is this final date that determines when an inmate found suitable for
    parole may be released. Under these regulations, a parolee cannot be released
    until the inmate has served at least this amount of time. (Id., § 2411, subds. (a),
    (b); see also In re Vicks (2013) 
    56 Cal. 4th 274
    , 313.)
    In 2012, Butler filed a petition in propria persona for writ of habeas corpus
    in the First District Court of Appeal. (In re Butler (2015) 
    236 Cal. App. 4th 1222
    ,
    1227-1228.) Among other contentions, Butler argued that the Board violated the
    state and federal Constitutions through its policy of deferring the calculation of an
    inmate’s base term until it found the inmate suitable for parole. (Ibid.) The Court
    of Appeal appointed counsel who assisted Butler in filing a supplemental habeas
    petition. (Id. at p. 1228.) The supplemental petition reiterated Butler’s
    constitutional argument and added a separate claim arguing that insufficient
    evidence supported the Board’s denial of parole in Butler’s case. (Id. at p. 1228 &
    fn. 2.) The Court of Appeal bifurcated the action into two separate cases; one
    6
    concerned whether sufficient evidence supported denial of parole in Butler’s case,
    while the other addressed the constitutionality of deferring base term calculations.
    (Ibid.) The Court of Appeal eventually issued orders to show cause in both cases.
    (Id. at p. 1228.)
    In the case dedicated to Butler’s challenge of the Board’s determination that
    he was unsuitable for parole, the Court of Appeal ultimately granted habeas corpus
    relief.5 (In re 
    Butler, supra
    , 236 Cal.App.4th at p. 1228, fn. 2.) On remand, the
    Board vacated its earlier denial of parole and held a new hearing at which it found
    Butler suitable for parole. (Ibid.) The Governor did not intervene, so Butler was
    released on parole in June 2014.6 (Ibid.)
    In the meantime, the parties began settlement negotiations in the case
    addressing Butler’s claim that the Board violated his constitutional rights by
    declining to calculate his base term. (In re 
    Butler, supra
    , 236 Cal.App.4th at pp.
    1228-1229.) The parties eventually agreed to a settlement in December 2013 that
    required the Board to calculate an inmate’s base and adjusted base terms at the
    inmate’s initial parole hearing (or, for inmates who already had their initial
    hearing, at the inmate’s next scheduled parole hearing). The stipulated order also
    required the Board to amend its regulations to codify this new approach. The
    Court of Appeal retained jurisdiction over the case until the amended regulations
    5     We ordered to depublish the Court of Appeal opinion granting Butler
    habeas corpus relief. (In re Butler, S217457, Supreme Ct. Mins., June 11, 2014.)
    6      For good reason, neither side argues that this case became moot once Butler
    was released. The parties agreed to settle Butler’s suit regarding base term
    calculations before Butler was released. Thus, his subsequent release has not
    mooted this action. A judgment is not moot if it “affects [the parties’] rights in the
    future.” (Eye Dog Foundation v. State Board of Guide Dogs for Blind (1967) 
    67 Cal. 2d 536
    , 542.) The settlement continues to bind the Board and thus affect its
    future rights and obligations.
    7
    became effective.7 Later, the Court of Appeal granted Butler’s request for
    attorney fees under Code of Civil Procedure section 1021.5. (Butler, 236
    Cal.App.4th at p. 1230.) The attorneys’ fees opinion discussed in some detail the
    Court of Appeal’s theory about the constitutional significance of base terms. (Id.
    at p. 1235-1245.) The Board did not petition for review.
    In the years since the parties settled the case before us, legislators and the
    electorate made major changes to California’s criminal justice system. Three of
    those changes are potentially relevant to the issues before us. First, Senate Bill
    No. 260 became effective on January 1, 2014. (Stats. 2013, ch. 312.) Under this
    law, inmates who committed indeterminate sentence offenses before turning 18
    years old would “be paroled regardless of the manner in which the [B]oard set
    release dates pursuant to subdivision (a) of Section 3041.” (§ 3046, subd. (c).)
    The result is that youth offenders are released once found suitable for parole,
    regardless of the minimum sentence that the offender’s base term would otherwise
    provide. In 2018, the Legislature extended the benefits of Senate Bill No. 260 to
    inmates who committed offenses at 25 years of age or younger. (Stats. 2017, ch.
    675.)
    Second, the Board altered its treatment of certain elderly inmates to comply
    with a February 2014 federal court order. (See Plata v. Brown (N.D. Cal. Feb. 10,
    2014, No. 3:01-cv-01351-JST).) The order required the Board to “[f]inalize and
    implement” new parole procedures for inmates who are at least 60 years old and
    who have served sentences of 25 years or more. (Id. at p. 3 ¶4(e).) In response,
    the Board announced expedited parole hearings for those elderly inmates who
    7       The Board has never promulgated the regulations that it agreed to enact in
    the settlement. After the Board filed its petition for review, the Court of Appeal
    stayed the Board’s rulemaking obligations under the settlement agreement.
    8
    have served a minimum of 25 years and a new policy of considering an inmate’s
    advanced age, long-term confinement, and diminished physical condition in
    determining their suitability for parole. (See Board of Parole Hearings, Cal. Dept.
    of Corrections and Rehabilitation, Elderly Parole Program (June 16, 2014) p. 2.)8
    Accordingly, as of June 2014, elderly inmates are also paroled upon a finding of
    suitability, regardless of what limit base terms would otherwise impose on the
    inmates’ release dates.
    Third — and most significantly –– the Legislature enacted Senate Bill No.
    230 in 2015. (Stats. 2015, ch. 470.) This legislation excised the language from
    former section 3041, subdivision (a) requiring the Board to set parolees’ release
    dates “in a manner that will provide uniform terms for offenses of similar gravity
    and magnitude with respect to their threat to the public” — the very language on
    which the Board relied in devising the base term system. Senate Bill No. 230
    provided instead that “[u]pon a grant of parole, the inmate shall be released subject
    to all applicable review periods. However, an inmate shall not be released before
    reaching his or her minimum eligible parole date as set pursuant to Section 3046.”
    (§ 3041, subd. (a)(4); Stats. 2015, ch. 470, § 1.) In turn, section 3046 provides that
    an inmate shall not be released until the inmate has served the greater of (1) seven
    years, or (2) a minimum term set by relevant statute, if one exists.9 (§ 3046, subd.
    (a).) Because of this legislation, base terms no longer control the release date for
    nonyouthful, nonelderly inmates either. Instead, those inmates’ indeterminate
    terms end when the inmate is both (1) found suitable for parole and (2) has served
    8     The Legislature recently codified these procedures under the Elderly Parole
    Program. (See Pen. Code, § 3055.)
    9      For example, the minimum term for second degree murder is either 15, 20,
    or 25 years, depending on the circumstances of the offense. (§ 190, subds. (a), (b),
    (d).)
    9
    their statutory minimum term (subject, of course, to the Board’s internal review
    procedures and the Governor’s power to reverse a grant of parole or request
    further review (see §§ 3041, subd. (b), 3041.1, 3041.2)).
    The most important aspect of these changes, for present purposes, is that
    base terms no longer play a defined role in determining the release date for any
    inmate sentenced to an indeterminate term.
    After SB 230 went into effect in January 2016, the Board moved to modify
    the December 2013 settlement agreement. According to the Board, it should be
    relieved of its obligations to calculate base terms and promulgate new regulations
    for calculating base terms at an inmate’s initial parole hearing. In essence, the
    Board argued that changes to the statutory scheme eliminated the Board’s
    authority or need to calculate base terms. The Court of Appeal denied the motion.
    It declined to modify the settlement order on the basis that the order “does not
    conflict” with any subsequent changes to the parole hearing process. The court
    also reasoned that the calculation of base terms was necessary to “assure life
    prisoners will not suffer constitutionally excessive punishment.”
    We granted the Board’s petition for review.10 We must now decide
    whether the changes discussed above are sufficiently material to require
    modification of the Board’s obligations to calculate inmates’ base terms.
    10     Butler argues we should dismiss our grant of review to penalize the Board
    for, according to Butler, willfully violating the settlement order. (See Gwartz v.
    Weilert (2014) 
    231 Cal. App. 4th 750
    , 757 [“An appellate court has the inherent
    power to dismiss an appeal by a party that refuses to comply with a lower court
    order”].) He also asserts that modification of the consent decree would violate the
    law of the case doctrine. (See People v. Gray (2005) 
    37 Cal. 4th 168
    , 196
    [explaining that the law of the case doctrine “generally precludes multiple
    appellate review of the same issue in a single case”].)
    Butler failed, however, to preserve these issues for our consideration. He
    did not file a petition for review or assert in his answer to the Board’s petition that
    10
    II.
    The parties’ settlement in this case was given effect in an injunctive order
    over which the Court of Appeal retained jurisdiction. Courts retain power to
    vacate or modify such orders at any point. (See Sontag Chain Stores Co. v.
    Superior Court (1941) 
    18 Cal. 2d 92
    , 94-95 (Sontag Chain Stores) [an injunctive
    order, “it has uniformly been held, is always subject, upon a proper showing, to
    modification or dissolution by the court which rendered it”]; see also Union
    Interchange, Inc. v. Savage (1959) 
    52 Cal. 2d 601
    , 604 (Union Interchange)
    [“When the decree is continuing in nature, directed at future events, it must be
    subject to adaptation as events may shape the need”].) A court may “modify or
    dissolve an injunction . . . upon a showing that there has been a material change in
    the facts upon which the injunction . . . was granted, that the law upon which the
    injunction . . . was granted has changed, or that the ends of justice would be served
    by the modification or dissolution of the injunction.” (Code Civ. Proc., § 533.)
    When a lower court rules on a motion to modify or vacate an injunctive order, we
    review it for abuse of discretion. (Salazar v. Eastin (1995) 
    9 Cal. 4th 836
    , 850
    (Salazar).) Under this standard, we consider the court’s legal conclusions de
    novo, and assess its factual findings for substantial evidence. (Haraguchi v.
    Superior Court (2008) 
    43 Cal. 4th 706
    , 711.) We will not reverse the court’s
    application of the law to the facts unless it is “arbitrary and capricious.” (Id. at p.
    712.) When a court decides not to modify an order despite a material change in
    the law fundamentally undermining the presumptions underlying the parties’
    acceptance of a settlement agreement, its decision ordinarily constitutes an abuse
    we should address these issues. (See Cal. Rules of Court, rule 28.1(c).) It is true
    that Butler did raise them in his answer to the petition for review, but only as a
    reason why the case did not warrant our review. Bringing up such an issue in this
    manner does not adequately preserve it for our review. (See Scottsdale Ins. Co. v.
    MV Transp. (2005) 
    36 Cal. 4th 643
    , 654, fn.2.)
    11
    of discretion. (See Welsch v. Goswick (1982) 
    130 Cal. App. 3d 398
    , 408-409
    [holding that the trial court abused its discretion in failing to modify a stipulated
    injunctive order following a material change in the law].)
    Whether changes in the law or circumstances affecting this case require
    modification of the injunctive order is a question sharply dividing the parties.
    Postsettlement changes to California’s criminal justice system are at issue here,
    principally the fact that base terms no longer directly control the release date for
    indeterminately-sentenced inmates. The Board argues that these changes are
    sufficiently material because they have “emptied base terms of any meaning and
    function.” Butler, by contrast, argues that modification is appropriate only when
    an injunctive order “conflicts with or violat[es]” current law. And, Butler
    continues, far from conflicting with these subsequent developments, the settlement
    order in fact furthers their purpose of reducing the state’s prison population.
    The Court of Appeal did not modify the injunction order. In continuing to
    embrace the stipulated agreement as it stood before the recent raft of legal
    changes, the court observed that the agreement did not directly conflict with the
    new legal regime and held that the changes in the law were not sufficiently
    material to warrant modification. Yet in so concluding, the appellate court did not
    fully consider the extent to which the intervening legal changes have undermined
    the settlement’s foundational assumptions, even if the changes fell short of
    creating an actual conflict with the settlement.
    In its argument, the Board relies on cases involving injunctions that conflict
    with current law. These cases can be distinguished from what is before us. In
    Salazar, for example, the trial court entered an injunctive order barring school
    districts for charging fees for transportation to and from school. 
    (Salazar, supra
    , 9
    Cal.4th at pp. 844-845.) We later held in Arcadia Unified School District v. State
    Department of Education (1992) 
    2 Cal. 4th 251
    that charging such fees did not
    12
    violate the California Constitution. After our decision in Arcadia, the trial court
    vacated its injunction but the Court of Appeal reversed. (Salazar, 9 Cal.4th at pp.
    848-849.) We later reversed the Court of Appeal, reasoning that Arcadia
    “eliminated the legal basis for the injunction.” (Salazar, 9 Cal.4th at p. 840; see
    also 
    id. at p.
    850 [“Here, because the injunction was inconsistent with our decision
    in Arcadia . . . to vacate it was not an abuse of discretion”].) The Board also relies
    on Systems Federation No. 91, Railway Employees’ Department, AFL-CIO v.
    Wright (1961) 
    364 U.S. 642
    . But Systems Federation also dealt with an injunctive
    order that conflicted with subsequent legal developments.
    This case is different. Although the relevant statutes and regulations have
    changed since the settlement, the Board faces no direct conflict between the
    injunctive order and existing statutes. Senate Bill No. 260 and Assembly Bill No.
    1308 require that youth offenders be released once found suitable for parole ––
    irrespective of any base term calculations. (Stats. 2013, ch. 312; Stats. 2017, ch.
    675.) And under the Elderly Parole Program, eligible elderly inmates who have
    served a minimum of 25 years may be released to parole if they are found suitable,
    regardless of what limit base terms would have otherwise imposed on the inmates’
    release dates. Finally, Senate Bill No. 230 requires that an inmate’s sentence ends
    once he is found suitable for parole and he has served his statutory minimum term.
    (Stats. 2015, ch. 470.) The order does not, as in Salazar and Systems Federation,
    prevent the bound party from doing something that it unquestionably has a right to
    do under current law. Instead, it requires the Board to do something that no longer
    has any apparent significance under its own statutes or regulations. For this
    reason, we think the cases on which the Board relies are inapposite.
    But neither does Butler persuade when he contends modification of a
    continuing injunction requires a conflict between the injunction and current law.
    To support this argument, Butler cites Firefighters v. City of Cleveland (1986) 478
    
    13 U.S. 501
    (Firefighters). Yet Firefighters is a federal case with no direct relevance
    to the question before us. It concerned a consent decree, under title VII of the
    Civil Rights Act of 1964, designed to remedy past racial discrimination in the City
    of Cleveland’s fire department. (Id. at pp. 505-508.) What the decree required,
    among other things, was that the City promote a specific number of minority
    firefighters to management positions. (Id. at p. 510.) The union representing the
    firefighters objected, arguing that the decree violated section 706(g) of title VII,
    which provides that “ ‘[n]o order of the court shall require the . . . promotion of an
    individual . . . if such individual was refused . . . advancement . . . for any reason
    other than discrimination on account of race, color, religion’ ” etc. (Firefighters,
    at p. 514, italics omitted, quoting 42 U.S.C. § 2000e-5 (g).)11 The U.S. Supreme
    Court rejected the argument, holding that consent decrees do not qualify as
    “ ‘order[s] of the court’ ” under section 706(g) because parties enter into them
    voluntarily. (Id. at p. 519; 
    id. at pp.
    521-522.)
    Also rejected by the U.S. Supreme Court was the union’s contention that a
    consent decree can only order relief that a court could impose itself after trial.
    
    (Firefighters, supra
    , 478 U.S. at p. 525 [a “federal court is not necessarily barred
    from entering a consent decree merely because the decree provides broader relief
    than the court could have awarded after a trial”]; 
    id. at p.
    524.) The court then
    went on to cabin this conclusion by noting, in language that Butler cites, that
    courts cannot accept a consent decree that “conflicts with or violates the statute
    upon which the complaint was based.” (Id. at p. 526.) Even assuming this case
    sheds any light on the general issue before us, the morsel of it Butler quotes ––
    11     The thrust of the union’s objection was that the consent decree would
    require the City to promote some minority firefighters who had not themselves
    been denied a promotion for discriminatory reasons. 
    (Firefighters, supra
    , 478
    U.S. at p. 514.)
    14
    read in context –– does not announce a standard for modification of an injunctive
    order. In light of the case’s procedural posture, it is quite clear the Firefighters
    court simply reiterated a more general principle underlying injunctive relief: that
    consent decrees should be consistent with governing law.
    Contrary to what Butler’s contention implies, flexibility is a touchstone of a
    court’s power to modify an injunctive order. (See Code Civ. Proc., § 533
    [allowing for modification based on “a material change in the facts” or even
    simply because “the ends of justice would be served by the modification”]; see
    also Sontag Chain 
    Stores, supra
    , 18 Cal.2d at p. 95 [describing courts’ power to
    modify injunctive orders as “an inherent one,” the exercise of which “is
    determined by the facts and circumstances of each particular case, with a view to
    administering justice between the litigants”].) Of course, statutory changes having
    only a tenuous bearing on a settlement agreement do not necessarily give rise to a
    requirement to modify the agreement. (See Professional Engineers v. Department
    of Transportation (1997) 
    15 Cal. 4th 543
    , 574 [holding that the trial court did not
    abuse its discretion when it failed to modify the initially-imposed terms of an
    injunction despite subsequent legislative changes].) Where modification of a
    consent decree is neither foreclosed because of constitutional considerations nor
    required because of sufficiently important changed circumstances, a court with
    jurisdiction over a consent decree has discretion to decide whether to modify the
    consent decree in light of the particular circumstances of the case. Given the
    nature and extent of statutory changes at issue, however, the relevant inquiry is
    therefore whether the statutory changes made since entry of the stipulated
    judgment are sufficiently material not only to permit, but in this case to require,
    modification of that judgment. (Sontag Chain 
    Stores, supra
    , 18 Cal.2d at p. 95.)
    In arguing that they are, the Board cites three changes: new rules for youth
    offenders (Senate Bill No. 260 and Assembly Bill No. 1308); the federal court
    15
    order relating to elderly inmates; and Senate Bill No. 230, which eliminated the
    statutory language on which the Board relied in devising base terms.
    Changes of such magnitude are consequential enough to require the
    settlement agreement’s modification. Although the new sources of law differ in
    certain details,12 all three are similar in establishing parole regimes that do not rely
    on an inmate’s base term. Together, they create a new legal landscape wherein
    base terms no longer play a defined role in the Board’s determination of parolee
    release dates. This is no trifling change. The terms to which the Board agreed in
    2013 were significant, but they were also limited: the Board agreed to calculate, at
    an earlier time and regardless of suitability for parole, inmates’ base terms —
    something that the Board’s regulations anticipated at some point for most inmates
    subject to indeterminate sentences. Our conclusion might be different if the
    agreement reflected the parties’ agreement regarding how the Board could
    comply, for example, with a responsibility to implement judicially-recognized
    constitutional principles in undertaking statutory parole determinations. But it is
    clear that the settlement agreement emanated from the then-existing statutory and
    regulatory structure and embodied, at best, an agnostic reading as to whether base
    terms had legal significance outside of that structure. The agreement expressly
    defines “base term” and “adjusted base term” by reference to the regulations that
    imbued those terms with legal significance. These regulations in turn reference
    section 3041, the statute that Senate Bill No. 230 amended. (See, e.g., Cal. Code
    Regs., tit. 15, § 2400 [“This article implements Penal Code section 3041”].) By
    citing these regulations, the settlement evinces an agreement that base terms have
    legal significance because they were pivotal in determining release dates for
    12     For example, youth offenders are exempt from Senate Bill No. 230’s
    requirement that inmates found suitable for parole nonetheless serve a statutorily-
    prescribed minimum sentence. (See § 3046, subd. (c).)
    16
    indeterminately-sentenced inmates. And advising inmates of their base terms had
    the salutary rehabilitative effect of informing each inmate of his or her earliest
    possible release date, if found suitable for parole.
    This review of the settlement agreement readily showcases how base terms
    were relevant in the settlement agreement for a specific reason. To wit: they were
    relevant in the existing regulatory structure. Indicia from the agreement, as well
    as the contemporary statutory and regulatory scheme, reveal that the settlement
    relied on base terms having legal significance within that framework.
    Specifically, an inmate’s calculated release date commenced with his or her
    adjusted base term, as contemplated in the settlement agreement. When that
    agreement was drafted, the Board was required by statute to set a provisional
    “parole release date” founded on “criteria” that would “provide uniform terms” for
    similar offenses. (Former § 3041, subd. (a).) The Board implemented that
    statutory mandate by promulgating regulations requiring the calculation of a base
    term, using a matrix that measured the seriousness of the offense and adjusted for
    aggravating or mitigating circumstances. 
    (Dannenberg, supra
    , 34 Cal.4th at p.
    1078 [noting that the Board promulgated base term calculations “[i]n response” to
    section 3041’s “requirements”].) The Board’s policy was to calculate the base
    term not before parole eligibility, but after he or she was found suitable for parole.
    The settlement agreement, however, changed the timing of an inmate’s base term
    calculation to his or her initial parole hearing or at his or her next scheduled
    hearing if the initial hearing had already occurred. What the settlement agreement
    did not alter is the Board’s underlying statutory and regulatory duty to calculate
    base terms.
    That base terms had some role to play in the sentencing regime strikes us as
    a “controlling fact[]” on which the injunction rested. (Sontag Chain 
    Stores, supra
    ,
    18 Cal.2d at p. 95.) Postsettlement legal changes make that controlling fact no
    17
    longer true. Base terms lack defined statutory significance –– and informing
    inmates of their base terms no longer has an obvious rehabilitative purpose
    because those terms no longer control the release dates for inmates found suitable
    for parole. Put another way, the settlement agreement presupposes that base terms
    form part of the framework for parolee release date calculations. As a result of the
    changes described above emphasizing the centrality of public safety
    considerations, base terms are no longer part of that framework. We therefore
    conclude that the changes in the law constitute a material change in the stipulated
    order. And we think that this change is sufficiently material to raise substantial
    doubts as to whether the injunction continues to be “necessary or desirable.”
    (Union 
    Interchange, supra
    , 52 Cal.2d at p. 604.)
    In holding that the postsettlement changes were not material, the Court of
    Appeal focused on whether the stipulated settlement “conflict[ed]” with the new
    legal regime. What this approach ignores is that Code of Civil Procedure section
    533 provides for modification of an injunctive order not only in instances of
    conflict but also upon a “material change in the facts.” The state’s parole regime
    has changed significantly enough to warrant relieving the Board of its obligations,
    even in the absence of a direct conflict between the settlement and current law.
    (See Sontag Chain 
    Stores, supra
    , 18 Cal.2d at p. 95 [whether to modify an
    injunctive order “is determined by the facts and circumstances of each particular
    case”].) The Court of Appeal erred in failing to recognize that the modified parole
    regime warranted modification of the injunctive order. A “disposition that rests on
    an error of law constitutes an abuse of discretion.” (In re Charlisse C. (2008) 
    45 Cal. 4th 145
    , 159.) In this case, postsettlement developments altering the parole
    regime were significant enough to constitute a material change in the facts,
    requiring modification of the injunctive order.
    18
    We would be compelled to uphold the original injunction if constitutional
    considerations required the Board to calculate inmates’ base terms. And indeed,
    the Court of Appeal also based its ruling on the motion to modify the injunction on
    the theory that base terms are necessary to “assure life prisoners will not suffer
    constitutionally excessive punishment.” What we nonetheless find is that,
    notwithstanding the importance of judicially-articulated constitutional
    considerations relevant to the Board’s functions, there is no constitutional basis to
    require continued adherence to the injunctive provisions obligating the Board to
    calculate base terms. We thus hold that the Court of Appeal also abused its
    discretion in ordering the Board to continue calculating base terms as a
    constitutional requirement.
    An inmate serving an indeterminate sentence has a constitutional right to a
    sentence not disproportionate to his or her offense. (See In re Lynch (1972) 
    8 Cal. 3d 410
    , 424; Solem v. Helm (1983) 
    463 U.S. 277
    , 284-288.) Writing during a
    time when California imposed indeterminate sentences for most felonies, we noted
    that the “oft-stated rule that a prisoner has no right to a term fixed at less than
    maximum . . . is . . . subject to the overriding constitutionally compelled
    qualification that the maximum may not be disproportionate to the individual
    prisoner’s offense.” (In re Rodriguez (1975) 
    14 Cal. 3d 639
    , 652). To guard
    against disproportionate punishment, Rodriguez required the parole authority to set
    a maximum term of incarceration for each inmate, based on the inmate’s
    culpability (as measured by the circumstances of the offense). (Ibid.) Rodriguez
    required that the parole authority release inmates once they reached their
    maximum term, even if the authority had not found the inmate suitable for parole.
    (Ibid.) Butler relies on Rodriguez to argue that the state Constitution requires the
    Board to continue setting inmates’ base terms, even after the postsettlement
    changes.
    19
    Under the cruel or unusual punishment clause (art. I, § 17) of the California
    Constitution, there is no question that an inmate sentenced to an indeterminate
    term cannot be held for a period grossly disproportionate to his or her individual
    culpability. 
    (Dannenberg, supra
    , 34 Cal.4th at p. 1096.) Still, in Dannenberg we
    explained that Rodriguez’s prophylactic measures are not necessarily required in
    the state’s current, mostly determinate sentencing regime. (Id. at p. 1097.) The
    petitioner in Dannenberg relied on Rodriguez to make a similar argument to the
    one Butler advances now. (Id. at p. 1096 [“Dannenberg contends . . . that such
    constitutional considerations impose upon the Board a general obligation to fix
    actual maximum terms, tailored to individual culpability, for indeterminate life
    inmates”].) Such a requirement, we explained, was necessary in a largely
    indeterminate sentencing regime — a regime that “imposed life maximums for a
    wide range of offenses, serious and less serious.” (Ibid.) But it was not
    constitutionally required for the “narrower category” of serious offenders who
    receive indeterminate sentences under current law. (Id. at p. 1097.) Because of
    their culpability, there is a “diminish[ed] possibility” that these serious offenders
    will suffer constitutionally excessive punishment. (Ibid.) We also emphasized
    that inmates may bring their claims directly to court through petitions for habeas
    corpus if they “believe, because of the particular circumstances of their crimes,
    that their confinements have become constitutionally excessive as a result.” (Id. at
    p. 1098.)
    Dannenberg declined to construe the state Constitution as requiring the
    Board to set maximum terms, across the board, for the serious offenders currently
    subject to indeterminate sentences. For good reason: To do otherwise would have
    effectively undone, without sufficient constitutional justification, the legislative
    design associated with limited continued use of indeterminate sentences in
    California for a circumscribed group of offenders. Although Dannenberg did not
    20
    weaken the constitutional requirement against grossly disproportionate sentences,
    it made clear that our prior ruling in Rodriguez imposing on the Board a general
    duty to fix maximum terms for indeterminate sentences was motivated by the
    more “comprehensive indeterminate sentencing system” that was in effect at that
    time. 
    (Dannenberg, supra
    , 34 Cal.4th at p. 1096.) The mostly determinate
    sentencing regime now in effect reflects the Legislature’s design to reduce the
    number of offenders receiving indeterminate sentences, thereby limiting the
    possibility that these serious offenders will suffer constitutionally excessive
    punishment. (Id. at p. 1097.)
    Given these changes, we see no reason to nonetheless enshrine base terms
    as constitutionally required. The Board promulgated base term regulations in
    response to the Legislature’s instruction to establish “criteria” that would promote
    sentence uniformity for inmates serving lifetime sentences. 
    (Dannenberg, supra
    ,
    34 Cal.4th at pp. 1078-1079.) The Board may not, however, release an inmate
    until the individual no longer poses a threat to “public safety,” regardless of any
    base term calculation. (Id. at pp. 1083-1084.) In fact, we specifically instructed
    the Board to “eschew term uniformity” if public safety considerations warrant a
    sentence that went beyond a calculated base term. (Id. at p. 1083, italics omitted.)
    Thus, base term calculations were designed to set forth an inmate’s minimum
    sentence, not to reflect the maximum sentence permitted by the Constitution.13
    Nor do base terms function, in a system focusing parole determinations on
    public safety considerations, as a workable measure of constitutional
    proportionality. A sentence violates the prohibition against unconstitutionally
    13     In its July 27, 2016 order denying the motion to modify the stipulated
    agreement, the Court of Appeal also recognized that base terms do not represent
    inmates’ maximum terms of incarceration (acknowledging that “the base term no
    longer represents the maximum term that can actually be imposed on a life
    prisoner”).
    21
    disproportionate sentences only if it is so disproportionate that it “shocks the
    conscience.” (In re 
    Lynch, supra
    , 8 Cal.3d at p. 424.) Courts engage in a broad,
    fact-specific inquiry when assessing constitutional proportionality claims,
    considering the “totality of the circumstances surrounding the commission of the
    offense.” (People v. Dillon (1983) 
    34 Cal. 3d 441
    , 479.) Calculating base terms,
    in contrast, is best understood as an exercise designed to promote sentencing
    uniformity in the absence of other safeguards. 
    (Dannenberg, supra
    , 34 Cal.4th at
    pp. 1078-1079). And the two-factor matrix method used to calculate a base term,
    for example, does not significantly address factors relating to the offender, such as
    “his age, prior criminality, personal characteristics, and state of mind.” 
    (Dillon, supra
    , 34 Cal.3d at p. 479.) Calculating a base term does not serve as a judgment
    on constitutional proportionality. Moreover, the Board has discretion to increase
    the length of terms set forth in a base term calculation based on policy
    considerations. 
    (Dannenberg, supra
    , at p. 1094, fn.15.) So a base term
    calculation is, at best, ill-suited to serve as a measure for assessing a sentence’s
    constitutional proportionality.
    Butler urges us to eschew Dannenberg’s reasoning because its
    interpretation construed the prior version of section 3041. Butler is indeed correct
    that much of the opinion discusses language in former section 3041, subdivision
    (a) that Senate Bill No. 230 excised. 
    (Dannenberg, supra
    , 34 Cal.4th at pp. 1078-
    1095.) But the aforementioned passages from Dannenberg are present in a
    different portion of the opinion, addressing a distinct constitutional argument that
    does not depend on the validity of section 3041’s previous incarnation. (Id. at pp.
    1096-1098.) What we considered in that portion of the opinion was whether the
    state Constitution required the Board to measure each inmate’s culpability for the
    purpose of guarding against unconstitutionally excessive punishment. We
    answered in the negative, at least for a regime where only a subset of defendants
    22
    are allocated indeterminate sentences. The postsettlement changes to section
    3041, subdivision (a) have not undermined the force of that aspect of the opinion.
    In effect, California’s current and mostly determinate sentencing laws,
    along with statutory reforms to the parole process, have all but rendered specific
    base term calculations for individuals subject to parole determinations unnecessary
    as a means of ensuring against unconstitutionally excessive punishment. Plainly,
    defendants retain the ability to perform the base term calculation or something
    equivalent and submit it to the Board for consideration. Moreover, the Board
    retains responsibility to take account, in its parole determinations, of public safety
    concerns that a base term calculation could have illuminated. (See Cal. Code
    Regs., tit. 15, § 2281, subd. (a) [explaining that the standard for parole suitability
    is whether “the prisoner will pose an unreasonable risk of danger to society if
    released from prison”].) For example, the Board was required, in calculating base
    terms for certain life offenses, to consider factors such as the crime’s “threat to the
    public,” as well as mitigating or aggravating circumstances. (Cal. Code Regs., tit.
    15, § 2403, subd. (g).) But it can take account of such concerns without
    calculating base terms.
    23
    III.
    The settlement agreement approved by the parties in 2013 required the
    Board to calculate an inmate’s base term at his or her initial parole hearing. At the
    time the parties ratified that agreement, a calculated base term directly impacted
    the release date for inmates serving indeterminate life sentences. Not so today.
    Instead, the release date for indeterminately-sentenced adult inmates — like Butler
    — is now guided by the date when an inmate has served the statutory minimum
    term and is found suitable for parole based on statutory public safety-related
    criteria, subject to limited exception. These changes to California’s criminal
    justice system do not diminish the societal interest in avoiding arbitrary parole
    determinations. They do, however, dictate that base terms no longer directly
    control the release date for prisoners subject to indeterminate sentences. That
    these statutory changes are material to these parties’ agreement requires, legally
    and practically, modification of the injunctive order by the Court of Appeal.
    Moreover, sentencing in California involves primarily determinate sentences and
    parole determinations involving public safety considerations –– so specific base
    term calculations are not a constitutionally necessary measure for guarding
    inmates serving indeterminate sentences against disproportionate punishment.
    We reverse the judgment of the Court of Appeal and order the settlement
    agreement modified so that the Board of Parole Hearings is relieved of its
    obligations to calculate base terms and adjusted base terms.
