    In re MOHAMMAD
    S259999
    Opinion of the Court by Cantil-Sakauye, C. J.
    This case asks whether Proposition 57, The Public Safety
    and Rehabilitation Act of 2016, requires California’s
    Department of Corrections and Rehabilitation (the Department)
    to provide early parole consideration to individuals currently
    serving a term of incarceration for a violent felony.
    Petitioner Mohammad Mohammad was incarcerated after
    having been convicted of nine violent felony counts and six
    nonviolent felony counts. The trial court ordered all terms to be
    served consecutively.       After petitioner’s conviction, the
    electorate approved Proposition 57 in November 2016, which
    added section 32 to article I of the California Constitution to
    provide, in relevant part, that “[a]ny person convicted of a
    nonviolent felony offense and sentenced to state prison shall be
    eligible for parole consideration after completing the full term
    for his or her primary offense.” (Cal. Const., art. I, § 32, subd.
    (a)(1).)1 The ballot initiative also directed the Department to
    “adopt regulations in furtherance of these provisions” and
    instructed the Secretary of the Department to “certify that these
    1
    Article I, subdivisions 32(a), 32(a)(1), 32(a)(1)(A), and
    32(b) of the California Constitution are referred to in this
    opinion as “article I, section 32(a),” “article I, section 32(a)(1),”
    “article I, section 32(a)(1)(A),” and “article I, section 32(b).”
    1
    In re MOHAMMAD
    Opinion of the Court by Cantil-Sakauye, C. J.
    regulations protect and enhance public safety.” (Art. I, § 32,
    subd. (b).)
    The Department subsequently adopted regulations
    implementing early parole consideration under article I, section
    32.2 Those regulations exclude from nonviolent offender early
    parole consideration any inmate who “is currently serving a
    term of incarceration for a ‘violent felony[.]’ ” (Cal. Code Regs.,
    tit. 15, § 3490, subd. (a)(5).)3 The regulations state that a
    “ ‘[v]iolent felony’ is a crime or enhancement as defined in
    subdivision (c) of Section 667.5 of the Penal Code.” (Id., § 3490,
    subd. (c).)
    Consistent with those regulations, the Department
    determined petitioner was ineligible for nonviolent offender
    early parole consideration because he was serving a term of
    incarceration for a violent felony. Petitioner challenged that
    determination, and the Court of Appeal granted relief, holding
    that the language of article I, section 32(a) requires early parole
    consideration for any inmate convicted of a nonviolent felony
    even when that inmate was also convicted of a violent felony.

    The Department refers to early parole consideration under
    article I, section 32 as “nonviolent offender parole review.”

    2
    In re MOHAMMAD
    Opinion of the Court by Cantil-Sakauye, C. J.
    We granted review to decide the validity of the
    Department’s regulation prohibiting early parole consideration
    under the Proposition 57 scheme for inmates “currently serving
    a term of incarceration for a ‘violent felony.’ ” (Cal. Code Regs.,
    § 3490, subd. (a)(5).) While the matter was pending in this
    court, four other appellate courts disagreed with Mohammad
    and concluded the Department’s regulations properly excluded
    from early parole consideration inmates currently serving a
    term of incarceration for a violent felony offense.4
    We conclude that the Department acted within the
    authority provided by article I, section 32(b) when it adopted the
    regulation at issue here. In reaching this conclusion, we find
    the constitutional text is ambiguous concerning the application
    of article I, section 32(a) to an inmate like petitioner who is
    currently serving a term of incarceration for a violent felony
    offense. Considering the text together with the materials
    presented to the voters, we hold that the Department’s approach
    is reasonably necessary to effectuate the purpose of
    Proposition 57. We therefore agree with the majority of the
    appellate courts, and reverse the decision of the Court of Appeal
    below.
    4
    We granted review in each of those four matters and
    deferred further action pending consideration and disposition of
    the issue before us in this case. (In re Guice (2021)

    In re MOHAMMAD
    Opinion of the Court by Cantil-Sakauye, C. J.
    I. FACTS AND PROCEDURAL HISTORY
    A. The Underlying Conviction
    In 2012, petitioner pleaded no contest to nine counts of
    second degree robbery (Pen. Code, § 211) and six counts of
    receiving stolen property (id., § 496, subd. (a)). The trial court
    designated one count of receiving stolen property to be the
    principal term and ordered the remaining counts to run
    consecutively. Petitioner was sentenced to 29 years in prison —
    three years for the principal term of receiving stolen property,
    eight months for each of the other counts of receiving stolen
    property, one year for each of the nine counts of robbery, and a
    total of 13 years eight months for gang enhancements attached
    to six counts (id., § 186.22, subds. (b)(1)(A), (b)(1)(C)).5
    Petitioner did not appeal.
    B. The Petition for Writ of Habeas Corpus and the
    Court of Appeal Opinion
    The   electorate    approved     Proposition      57   in   2016.
    Petitioner subsequently filed a request with the Department
    asking for early parole consideration.      He asserted that
    Proposition 57 requires early parole consideration for inmates
    who have completed the full term for a primary offense when
    that offense is nonviolent. He noted that the trial court in his
    case designated as the principal term one count of receiving
    stolen property, and that receiving stolen property is not defined
    as a violent felony under Penal Code section 667.5, subdivision
    (c). The Department denied petitioner’s request. Petitioner
    5
    The principal term is “the greatest term of imprisonment
    imposed by the court for any of the crimes, including any term
    imposed for applicable specific enhancements.” (Pen. Code,
    § 1170.1, subd. (a).)
    4
    In re MOHAMMAD
    Opinion of the Court by Cantil-Sakauye, C. J.
    filed a petition for a writ of habeas corpus in the Los Angeles
    County Superior Court. The superior court denied the petition
    in November 2018, agreeing with the Department.
    In January 2019, petitioner sought habeas corpus relief in
    the Court of Appeal. That court ultimately held in a published
    opinion that the Department’s regulations improperly excluded
    petitioner from early parole consideration. (Mohammad, supra,
    42 Cal.App.5th at p. 729.) The court focused on the language of
    the constitutional provision establishing parole consideration
    for “ ‘[a]ny person convicted of a nonviolent felony offense’ upon
    completion of ‘the full term of his or her primary offense.’ ”
    (Id. at p. 726, quoting art. I, § 32(a)(1).) This language, the court
    held, contains the sole requirement for early parole
    consideration under Proposition 57 — conviction of a nonviolent
    felony. (Mohammad, supra, 42 Cal.App.5th at p. 726.) Early
    parole consideration is therefore required, according to the
    Court of Appeal, “so long as [the inmate] commits ‘a’ single
    nonviolent felony offense — even if that offense is not his or her
    only offense.” (Ibid.)
    In support of its conclusion, the court pointed to the
    constitutional language defining the “ ‘full term for the primary
    offense’ as ‘the longest term of imprisonment imposed by the
    court for any offense, excluding the imposition of an
    enhancement, [a] consecutive sentence, or [an] alternative
    sentence.’ ” (Mohammad, supra, 42 Cal.App.5th at p. 726,
    quoting art. I, § 32(a)(1)(A).) Under this provision, the court
    asserted, “an inmate who is ‘convicted of a nonviolent felony
    offense’ not only remains eligible if he or she is sentenced to a
    consecutive sentence, but in fact, becomes eligible for an early
    parole hearing prior to serving that consecutive sentence.”
    5
    In re MOHAMMAD
    Opinion of the Court by Cantil-Sakauye, C. J.
    (Mohammad, supra, 42 Cal.App.5th at p. 727, quoting art. I,
    § 32(a)(1).)
    The court rejected the Department’s regulations as
    incompatible with the language of article I, section 32(a)(1).
    (Mohammad, supra, 42 Cal.App.5th at pp. 726–727.) The court
    noted that those regulations “dictate a different result, but only
    by impermissibly defining and limiting the universe of eligible
    inmates to ‘nonviolent offenders’ — a term that does not appear
    anywhere in [article I,] section 32(a)(1).” (Id. at p. 726, quoting
    Cal. Code Regs., § 3491.) The court declined to consider the
    ballot materials presented to the voters, determining that
    review of extrinsic sources was unnecessary because the
    language of the constitutional provision itself was unambiguous.
    (Mohammad, supra, 42 Cal.App.5th at p. 727, citing Silicon
    Valley Taxpayers’ Assn., Inc. v. Santa Clara County Open Space
    Authority (2008) 
    44 Cal.4th 431
    , 444–445.)
    The Court of Appeal acknowledged that the Department’s
    argument “has some intuitive appeal. It cannot be, the
    argument goes, that voters intended a defendant who is
    convicted of more crimes, i.e., both violent and nonviolent
    felonies, to be eligible for early parole consideration while a
    defendant convicted of fewer crimes, i.e., the same violent felony
    but no nonviolent felonies, is not.” (Mohammad, supra,
    42 Cal.App.5th at p. 727.)     But this “intuitive appeal” is
    overcome and that interpretation foreclosed, the court
    determined, by the language of the provision. (Id. at pp. 727–
    728.)
    The court also noted that petitioner’s case “is an unusual
    one” in that the trial court designated a nonviolent felony as
    petitioner’s principal term, while “[o]ften” an individual’s most
    6
    In re MOHAMMAD
    Opinion of the Court by Cantil-Sakauye, C. J.
    serious violent felony is deemed the principal term.
    (Mohammad, supra, 42 Cal.App.5th at p. 728.) The court
    suggested that these facts — “when an inmate becomes eligible
    for early parole consideration before serving time for any of his
    or her violent felony offenses” — “will not frequently arise.”
    (Ibid., fn. omitted.)
    We granted the Attorney General’s petition for review.
    After the filing of our opinion in In re Gadlin (2020) 
    10 Cal.5th 915
     (Gadlin), we granted petitioner’s motion to file
    supplemental briefing to address Gadlin as well as Proposition
    20, a ballot initiative that was rejected by the voters in
    November 2020.
    II. DISCUSSION
    A. Proposition 57
    We recently described the history of Proposition 57 in
    Gadlin. We noted there that the California Legislature and the
    electorate have taken steps to decrease the California prison
    population, including the electorate’s approval of Proposition 57
    in November 2016. (Gadlin, supra, 10 Cal.5th at pp. 922–923,
    citing Cal. Sect. of State, Statement of Vote Summary Pages
    (2016)      p. 12      [as of Dec. 28, 2021].) The
    initiative, in relevant part, added section 32 to article I of the
    California Constitution, which provides: “Any person convicted
    of a nonviolent felony offense and sentenced to state prison shall
    be eligible for parole consideration after completing the full term
    for his or her primary offense.” (Art. I, § 32(a)(1).) Article I,
    section 32 further specifies that “the full term for the primary
    offense means the longest term of imprisonment imposed by the
    court for any offense, excluding the imposition of an
    7
    In re MOHAMMAD
    Opinion of the Court by Cantil-Sakauye, C. J.
    enhancement, consecutive sentence, or alternative sentence”
    (id., subd. (a)(1)(A)),6 directs the Department to “adopt
    regulations in furtherance of these provisions” (id., § 32(b)), and
    instructs the Secretary of the Department to “certify that these
    regulations protect and enhance public safety” (ibid.).
    We described the purposes of the constitutional provision
    in Gadlin: “ ‘[T]o enhance public safety, improve rehabilitation,
    and avoid the release of prisoners by federal court order,
    notwithstanding anything in this article or any other provision
    of law.’ ” (Gadlin, supra, 10 Cal.5th at p. 923, quoting art. I,
    § 32(a).) Uncodified portions of Proposition 57 further identify
    the initiative’s purpose and intent, in relevant part, as follows:
    “1. Protect and enhance public safety. [¶] 2. Save money by
    reducing wasteful spending on prisons. [¶] 3. Prevent federal
    courts from indiscriminately releasing prisoners. [¶] 4. Stop
    the revolving door of crime by emphasizing rehabilitation,
    especially for juveniles.” (Voter Information Guide, Gen. Elec.
    (Nov. 8, 2016) text of Prop. 57, § 2, p. 141.) The initiative further
    states that the “act shall be liberally construed to effectuate its
    purposes.” (Id., § 9, p. 146.)
    B. The Department’s Regulations
    In March 2017, the Department proposed emergency
    regulations to implement Proposition 57. As we described in
    Gadlin, those emergency regulations were replaced by final
    6
    This definition of an individual’s “primary offense” for
    purposes of early parole consideration renders the primary
    offense distinct from an individual’s principal term. (See art. I,
    § 32(a)(1).) As noted above, the principal term is “the greatest
    term of imprisonment imposed by the court for any of the crimes,
    including any term imposed for applicable specific
    enhancements.” (Pen. Code, § 1170.1, subd. (a).)
    8
    In re MOHAMMAD
    Opinion of the Court by Cantil-Sakauye, C. J.
    regulations in May 2018 and subsequently amended in response
    to various appellate opinions. (Gadlin, supra, 10 Cal.5th at
    pp. 924–925.)    The regulations define a “determinately-
    sentenced nonviolent offender” as an inmate who is not, among
    other things, “currently serving a term of incarceration for a
    ‘violent felony.’ ”  (Cal. Code Regs., § 3490, subd. (a)(5).)
    Further, the regulations define a “violent felony” for purposes of
    early parole consideration as “a crime or enhancement” listed in
    Penal Code section 667.5, subdivision (c). (Id., § 3490, subd. (c).)
    Other provisions of the regulations exclude from early
    parole consideration individuals “currently serving a
    determinate term prior to beginning a term of life with the
    possibility of parole or prior to beginning a term for an in-prison
    offense that is a ‘violent felony’ ” (Cal. Code Regs., § 3490, subd.
    (a)(4)) and those “currently serving a term of incarceration for a
    nonviolent felony offense after completing a concurrent
    determinate term for a ‘violent felony’ ” (id., § 3490, subd. (a)(6)).
    Additionally, the regulations detail the eligibility criteria for
    both determinately-sentenced offenders (see id., §§ 3490–3491)
    and indeterminately-sentenced offenders (see id., §§ 3495–
    3496). Like the regulatory provision defining a “determinately-
    sentenced nonviolent offender” (id., § 3490, subd. (a)), the
    regulations define an “indeterminately-sentenced nonviolent
    offender” as an inmate who is not, among other things,
    “currently serving a term of life with the possibility of parole for
    a ‘violent felony’ ” (id., § 3495, subd. (a)(3)). Because petitioner’s
    exclusion from early parole consideration is governed solely by
    section 3490, subdivision (a)(5) of the California Code of
    Regulations, however, we decline to address in this case the
    validity of any other portion of the regulations.
    9
    In re MOHAMMAD
    Opinion of the Court by Cantil-Sakauye, C. J.
    C. Standard of Review and Principles of Statutory
    Interpretation
    We apply well settled principles to determine the validity
    of regulations promulgated by a state agency. As in Gadlin, we
    acknowledge that although these precepts “have traditionally
    been applied in the context of a state agency’s regulations
    addressing statutes enacted by the Legislature (Gadlin, supra,
    10 Cal.5th at p. 925, citing Morris v. Williams (1967) 
    67 Cal.2d 733
    , 748 (Morris)), the parties here do not assert that “the
    relevant principles of interpretation differ when an agency has
    promulgated regulations to give force to a constitutional
    provision, rather than a statutory provision” (id. at p. 926).
    In undertaking this analysis, we ask whether the
    regulation is “ ‘consistent and not in conflict with’ ” the
    constitutional provision that authorizes it (see Morris, supra,
    67 Cal.2d at p. 748, italics omitted, quoting Gov. Code, former
    § 113747) and whether the regulation is reasonably necessary to
    effectuate the purpose of the authorizing law (Morris, supra,
    67 Cal.2d at p. 749; see also Gov. Code, § 11342.2 [“Whenever by
    the express or implied terms of any statute a state agency has
    authority to adopt regulations to implement, interpret, make
    specific or otherwise carry out the provisions of the statute, no
    regulation adopted is valid or effective unless consistent and not
    in conflict with the statute and reasonably necessary to
    effectuate the purpose of the statute”]; Woods v. Superior Court
    (1981) 
    28 Cal.3d 668
    , 679 (Woods)). Our task “ ‘ “is to decide
    whether the [agency] reasonably interpreted the legislative
    mandate.” [Citation.] ’ ” (Woods, supra, 28 Cal.3d at p. 679,
    7
    Former section 11374 of the Government Code was
    renumbered as section 11342.2. (Stats. 1979, ch. 567, §§ 1–2.)
    10
    In re MOHAMMAD
    Opinion of the Court by Cantil-Sakauye, C. J.
    quoting Credit Ins. Gen. Agents Assn. v. Payne (1976) 
    16 Cal.3d 651
    , 657.) In doing so, we presume the validity of the regulation
    (Assn. of California Ins. Companies v. Jones (2017) 
    2 Cal.5th 376
    , 389); the burden lies with the party challenging the
    regulation to show its invalidity (Payne, supra, 16 Cal.3d at
    p. 657). Because this inquiry poses a question of law (see
    Western States Petroleum Assn. v. Board of Equalization (2013)
    
    57 Cal.4th 401
    , 415), we review the Court of Appeal’s decision
    de novo. (See People v. Gonzales (2018) 
    6 Cal.5th 44
    , 49, citing
    Apple Inc. v. Superior Court (2013) 
    56 Cal.4th 128
    , 135.)
    Our “primary concern” in construing a constitutional
    provision enacted through voter initiative is “giving effect to the
    intended purpose of the provisions at issue” (California
    Cannabis Coalition v. City of Upland (2017) 
    3 Cal.5th 924
    , 933)
    by applying “the same principles that govern statutory
    construction” (People v. Rizo (2000) 
    22 Cal.4th 681
    , 685, citing
    Horwich v. Superior Court (1999) 
    21 Cal.4th 272
    , 276). In doing
    so, we look to the text of the constitutional provision at issue
    and, as appropriate, extrinsic sources such as an initiative’s
    ballot materials. (See City of Upland, supra, 3 Cal.5th at
    pp. 933–934.) Although we are obligated to strike down
    regulations that alter or amend the constitutional provision or
    its scope (Woods, supra, 28 Cal.3d at p. 679, citing Morris, supra,
    67 Cal.2d at p. 748), our role is not to examine the wisdom of the
    regulations but their legality (Woods, supra, 28 Cal.3d at p. 679,
    quoting Morris, supra, 67 Cal.2d at p. 737). “Such a limited
    scope of review constitutes no judicial interference with the
    administrative discretion in that aspect of the rulemaking
    function which requires a high degree of technical skill and
    expertise.” (Woods, supra, 28 Cal.3d at p. 679.)
    11
    In re MOHAMMAD
    Opinion of the Court by Cantil-Sakauye, C. J.
    D. The Language of Proposition 57
    We begin our analysis with the language of the
    constitutional provisions enacted by Proposition 57. Article I,
    section 32(a)(1) states: “Any person convicted of a nonviolent
    felony offense and sentenced to state prison shall be eligible for
    parole consideration after completing the full term for his or her
    primary offense.” Article I, section 32(a)(1)(A) defines the “full
    term for the primary offense” as “the longest term of
    imprisonment imposed by the court for any offense, excluding
    the imposition of an enhancement, consecutive sentence, or
    alternative sentence.” And article I, section 32(b) provides that
    the Department shall “adopt regulations in furtherance of these
    provisions.” The question here is whether these constitutional
    provisions require the Department to provide early parole
    consideration when the inmate is currently serving a term for a
    violent felony.
    As noted, the Court of Appeal below concluded that the
    voters intended to extend early parole consideration to an
    inmate convicted of “a” nonviolent felony, regardless of whether
    that inmate was currently serving a term for a violent felony.
    (Mohammad, supra, 42 Cal.App.5th at p. 725; see id. at pp. 725–
    726.) The court declined to consider the ballot materials
    presented to the voters, concluding “[t]here is nothing
    ambiguous about what [article I,] section 32(a)(1) means in this
    case . . . .” (Id. at p. 727.) The Department asserts, on the other
    hand, that the constitutional provisions are ambiguous and
    require consideration of the ballot materials to determine the
    intent of the electorate.
    We first examine whether the constitutional language is
    ambiguous; if the text “is unambiguous and provides a clear
    12
    In re MOHAMMAD
    Opinion of the Court by Cantil-Sakauye, C. J.
    answer, we need go no further.” (Microsoft Corp. v. Franchise
    Tax Bd. (2006) 
    39 Cal.4th 750
    , 758.) When a constitutional
    provision is “ ‘clear and unambiguous’ ” it should be given its
    ordinary meaning. (People v. Valencia (2017) 
    3 Cal.5th 347
    , 357,
    quoting Lungren v. Deukmejian (1988) 
    45 Cal.3d 727
    , 735.)
    “The words of the statute must be construed in context, keeping
    in mind the statutory purpose . . . .” (Dyna-Med, Inc. v. Fair
    Employment & Housing Com. (1987) 
    43 Cal.3d 1379
    , 1387
    (Dyna-Med).) If the text is ambiguous, it is appropriate to
    examine the ballot materials before the voters. (People v.
    Valencia (2017) 
    3 Cal.5th 347
    , 364, citing Robert L. v. Superior
    Court (2003) 
    30 Cal.4th 894
    , 905.)
    Article I, section 32(a)(1) establishes early parole
    consideration for “[a]ny person convicted of a nonviolent felony
    offense . . . after completing the full term for his or her primary
    offense.” This language does not expressly address whether
    inmates with nonviolent felony convictions who are currently
    serving a prison term for a violent felony are eligible for early
    parole consideration. The parties and appellate courts have
    offered various interpretations of this provision.
    The Court of Appeal concluded the language is clear and
    unambiguous: An inmate convicted of “a” nonviolent felony
    would be eligible for early parole consideration after completing
    the full term of the primary offense. (Mohammad, supra,
    42 Cal.App.5th at p. 725; see id. at pp. 725–726.) The court
    stated that the requirement that an inmate be convicted of “a”
    nonviolent felony “takes the singular form, which indicates it
    applies to an inmate so long as he or she commits ‘a’ single
    nonviolent felony offense — even if that offense is not his or her
    only offense.” (Id. at p. 726.) The court also determined the
    inclusion of the term “primary offense” in the constitutional
    13
    In re MOHAMMAD
    Opinion of the Court by Cantil-Sakauye, C. J.
    provision further indicates the electorate would have
    understood that inmates “might be serving a sentence for more
    than one offense, i.e., a primary offense and other secondary
    offenses.”   (Ibid.)    Moreover, the court noted that the
    constitutional definition of the “full term for the primary
    offense” specifically references (and excludes) the imposition of
    a consecutive sentence. (Ibid.)
    Considered alone and outside of the context of the entire
    initiative, the Court of Appeal’s interpretation is a plausible
    reading of the language that is, on its face, consistent with
    article I, section 32(a).8 But language that seems plain when
    considered in isolation may be ambiguous when examined
    within the context of the scheme it implements. (See, e.g., Small
    v. United States (2005) 
    544 U.S. 385
    , 388 [finding phrase
    “convicted in any court” to be ambiguous when determining
    whether statute included a conviction in a foreign court], citing
    Nixon v. Missouri Municipal League (2004) 
    541 U.S. 125
    , 132
    [“ ‘any’ ” can mean “different things depending upon the
    setting”]; People v. Woodhead (1987) 
    43 Cal.3d 1002
    , 1008
    [noting the term “convicted” “may have different meanings in
    8
    Another Court of Appeal reached the same conclusion,
    finding that the language of section 32(a)(1) “support[s] a
    conclusion that an inmate is eligible for early parole
    consideration after completing his or her primary offense if the
    inmate was convicted of a nonviolent offense, even if the term
    for that nonviolent offense was not designated as the primary
    offense, and even if the inmate was also convicted of one or more
    violent offenses . . . .” (In re Douglas, supra, 62 Cal.App.5th at
    p. 731.) Ultimately, however, that appellate court concluded
    that interpreting the initiative in such a manner would lead to
    absurd results not intended by the electorate and thus declined
    to do so. (Id. at pp. 732–734.)
    14
    In re MOHAMMAD
    Opinion of the Court by Cantil-Sakauye, C. J.
    different contexts, or even different meanings within a single
    statute”].)
    We have found similar language to be ambiguous. (In re
    Reeves (2005) 
    35 Cal.4th 765
     (Reeves).) In Reeves, we considered
    a statute that provided “ ‘any person who is convicted of a
    [violent] felony offense . . . shall accrue no more than 15 percent
    of worktime credit . . . .’ ” (Id. at p. 768, fn. omitted, quoting
    Pen. Code, § 2933.1, subd. (a).) The issue in Reeves was whether
    an inmate convicted of both nonviolent and violent felonies was
    subject to the 15 percent credit limit. (Id. at p. 770.) We noted
    that the “seemingly plain language” of the statute was subject
    to various possible interpretations based on the term “ ‘is
    convicted.’ ” (Id. at p. 770; see id. at p. 771 [“ ‘any person who is
    convicted of a [violent] felony offense’ [citation], might
    conceivably refer simply to a point of historical fact”].) We
    therefore determined that “the conclusion that [the statute] is
    ambiguous, at least as applied to the facts of this case, seems
    inescapable.” (Id. at pp. 770–771.)
    The constitutional provision here contains language
    nearly identical to the statutory language we considered in
    Reeves. Article I, section 32(a) does not directly state whether
    an inmate like petitioner — who has nonviolent felony
    convictions but is currently serving a term of incarceration for a
    violent felony — would be eligible for early parole consideration.
    Like in Reeves, it “seems inescapable” that the language is
    ambiguous as it applies to inmates like petitioner. (Reeves,
    supra, 35 Cal.4th at pp. 770–771.)
    Further, the appellate courts and the parties here advance
    various interpretations of article I, section 32(a) that reflect
    ambiguities in the constitutional language. Petitioner, for
    15
    In re MOHAMMAD
    Opinion of the Court by Cantil-Sakauye, C. J.
    example, asserts that inmates convicted of a nonviolent felony
    as their primary offense are eligible for early parole
    consideration “once they have served the full term for that
    offense.” (Italics added.) In other words, under petitioner’s
    view, early parole consideration is required when an inmate’s
    primary offense is a nonviolent felony even if the inmate is
    currently serving a term for a violent felony, but not when the
    inmate’s primary offense is a violent felony and the inmate is
    currently serving a term for a nonviolent felony.9
    A concurring opinion in another appellate decision
    provides a different approach: When an inmate has been
    convicted of a violent felony offense that is deemed the primary
    offense and also has been convicted of a nonviolent felony
    offense, the inmate is eligible for nonviolent offender parole
    consideration after serving the sentence for the violent felony.
    (In re Douglas, supra, 62 Cal.App.5th at p. 735 (conc. opn. of
    Robie, Acting P. J.).) The Department asserts the language
    permits the exclusion of inmates who have nonviolent felony
    9
    Petitioner asserts this approach is consistent with the
    approach adopted by the Court of Appeal below. We disagree.
    Although the court’s discussion took place in the context of
    evaluating petitioner’s eligibility for early parole consideration
    (and petitioner’s primary offense was a nonviolent felony), no
    language in the Court of Appeal’s opinion limited its holding to
    inmates whose primary offense was a nonviolent felony. Indeed,
    the Court of Appeal’s language was quite broad: “under
    [article I, section 32(a) and article I, section 32(a)(1)(A)], an
    inmate who is serving an aggregate sentence for more than one
    conviction will be eligible for an early parole hearing if one of
    those convictions was for ‘a’ nonviolent felony offense.”
    (Mohammad, supra, 42 Cal.App.5th at p. 726.)
    16
    In re MOHAMMAD
    Opinion of the Court by Cantil-Sakauye, C. J.
    convictions and are currently serving a term of incarceration for
    a violent felony offense.
    The language of article I, section 32(a) alone does not tell
    us which of these interpretations is correct. That there are
    several plausible interpretations of the constitutional language
    indicates the meaning of the text is ambiguous. (See People v.
    Gonzales (2018) 
    6 Cal.5th 44
    , 52 [considering ballot materials
    when statutory language “could have several possible
    interpretations”]; Arias v. Superior Court (2009) 
    46 Cal.4th 969
    ,
    979 [“there is no need to construe a provision’s words when they
    are clear and unambiguous and thus not reasonably susceptible
    of more than one meaning”], citing People v. Leal (2004)
    
    33 Cal.4th 999
    , 1007, People v. Gardeley (1996) 
    14 Cal.4th 605
    ,
    621; see also In re Douglas, supra, 62 Cal.App.5th at p. 735
    (conc. opn. of Robie, Acting P. J.) [“It is clear section 32(a)(1) is
    ambiguous given the divergence of appellate opinions as to its
    meaning”].)
    Petitioner contends that our recent opinion in Gadlin
    compels a contrary conclusion. But in Gadlin, we found the
    language of article I, section 32(a)(1) to be unambiguous in other
    respects. (Gadlin, supra, 10 Cal.5th at p. 935.) There, we were
    asked to decide whether the Department could exclude from
    early parole consideration all inmates convicted of a sex offense
    requiring registration under Penal Code section 290, even when
    the Department’s regulations defined some of those inmates as
    nonviolent offenders. (Gadlin, supra, 10 Cal.5th at pp. 919–
    920.) We held it could not in light of the language of article I,
    section 32(a)(1), which provides that “[a]ny person convicted of
    a nonviolent felony offense” shall be eligible for early parole
    consideration. (Gadlin, supra, 10 Cal.5th at pp. 932–933.)
    Indeed, in so holding, we stated that “article I, section 32(a)(1),
    17
    In re MOHAMMAD
    Opinion of the Court by Cantil-Sakauye, C. J.
    although containing some terms that might be ambiguous in
    other respects, is not ambiguous concerning its scope regarding
    offenders who were previously convicted of a registerable sex
    offense or who are currently convicted of a registerable sex
    offense that the Department has itself defined as nonviolent.”
    (Gadlin, supra, 10 Cal.5th at p. 932, italics added.) Our holding
    was thus limited to the specific question before us in that case,
    and we acknowledged that the language of the constitutional
    provision might be ambiguous in other respects. Thus, Gadlin
    does not compel a conclusion that the constitutional provision is
    unambiguous as it relates to the distinct question before us now.
    We disapprove of the following opinions to the extent they have
    held the language of article I, section 32(a) is unambiguous in
    this context: In re Ontiveros (2021) 
    65 Cal.App.5th 899
    , 905
    [“We accept, for purposes of our opinion, that the text of
    Proposition 57 is clear and unambiguous”]; In re Douglas (2021)
    
    62 Cal.App.5th 726
    , 731.
    E. Consideration of the Ballot Materials
    Because the constitutional text provides “ ‘no definitive
    answer’ ” to the question before us (People v. Hazelton (1996)
    
    14 Cal.4th 101
    , 105, quoting People v. Coronado (1995)
    
    12 Cal.4th 145
    , 151), we consider the materials that were before
    the voters. (People v. Valencia, supra, 3 Cal.5th at p. 364, citing
    Robert L. v. Superior Court, supra, 30 Cal.4th at p. 905.)
    1. The ballot materials presented to the voters
    The voters were provided ballot materials that consisted
    of the official title and summary prepared by the Attorney
    18
    In re MOHAMMAD
    Opinion of the Court by Cantil-Sakauye, C. J.
    General, the analysis by the Legislative Analyst, and the
    arguments in favor of and against the proposition.10
    The official title and summary described the relevant
    provisions of Proposition 57 as follows:        “Allows parole
    consideration for persons convicted of nonviolent felonies, upon
    completion of prison term for their primary offense as defined.
    [¶] . . . [¶]   Requires Department of Corrections and
    Rehabilitation to adopt regulations to implement new parole
    and sentence credit provisions and certify they enhance public
    safety.” (Voter Information Guide, Gen. Elec., supra, Official
    Title and Summary, p. 54.)
    The analysis by the Legislative Analyst generally
    summarized California’s then-existing sentencing and parole
    consideration scheme, and described the changes to the parole
    system that would result were Proposition 57 to be adopted. The
    analysis described the proposed parole scheme as “parole
    consideration for nonviolent offenders” and stated that the
    initiative “changes the State Constitution to make individuals
    who are convicted of ‘nonviolent felony’ offenses eligible for
    parole consideration after serving the full prison term for their
    primary offense.” (Voter Information Guide, Gen. Elec., supra,
    analysis of Prop. 57 by Legis. Analyst, p. 56.) The analysis noted
    that “[a]lthough the measure and current law do not specify
    which felony crimes are defined as nonviolent, this analysis
    assumes a nonviolent felony offense would include any felony
    offense that is not specifically defined in statute as violent.”
    10
    The Arguments included an argument in favor of the
    initiative by the proponents followed by a rebuttal by the
    opponents, and an argument against the initiative by the
    opponents followed by a rebuttal by the proponents.
    19
    In re MOHAMMAD
    Opinion of the Court by Cantil-Sakauye, C. J.
    (Ibid.) Based on that assumption, the analysis estimated that,
    “[a]s of September 2015, there were about 30,000 individuals in
    state prison who would be affected by the parole consideration
    provisions of the measure.” (Ibid.) And the analysis estimated
    that eligible inmates “currently serve about two years in prison
    before being considered for parole and/or released” but under the
    initiative “would serve around one and one-half years in prison
    before being considered for parole and/or released.” (Ibid.)
    Finally, the arguments in favor of and against the
    initiative were presented to the voters. The proponents urged
    that Proposition 57 would allow “parole consideration for people
    with non-violent convictions who complete the full prison term
    for their primary offense.” (Voter Information Guide, Gen. Elec.,
    supra, argument in favor of Prop. 57, p. 58.) The proponents did
    not address whether individuals with nonviolent felony
    convictions who are currently serving a term of incarceration for
    a violent felony would be eligible for early parole consideration.
    The opponents’ rebuttal and argument against
    Proposition 57 asserted that the initiative would allow parole
    consideration for “VIOLENT CRIMINALS.” (Voter Information
    Guide, Gen. Elec., supra, rebuttal to argument in favor of
    Prop. 57, p. 58.) The opponents claimed the measure was
    “poorly drafted” and would allow for parole consideration for
    various crimes allegedly categorized by Proposition 57 as “non-
    violent.” (Id., p. 59.) The opponents asserted that if the measure
    passed “16,000 dangerous criminals, including those previously
    convicted of murder and rape, would be eligible for early
    release.” (Id., p. 59, italics omitted.) The opponents did not
    address whether individuals with nonviolent felony convictions
    who are currently serving a term of incarceration for a violent
    felony would be eligible for early parole consideration.
    20
    In re MOHAMMAD
    Opinion of the Court by Cantil-Sakauye, C. J.
    The proponents’ rebuttal responded by stating that the
    initiative would not authorize parole for violent offenders, and
    cited Brown v. Superior Court (2016) 
    62 Cal.4th 335
     for the
    position that Proposition 57 would apply “ ‘only to prisoners
    convicted of non-violent felonies.’ ” (Voter Information Guide,
    Gen. Elec., supra, rebuttal to argument against Prop. 57, p. 59,
    quoting Brown v. Superior Court, supra, 63 Cal.4th at p. 352.)
    The proponents emphasized, too, that “[v]iolent criminals as
    defined in Penal Code 667.5(c) are excluded from parole.” (Voter
    Information Guide, Gen. Elec., supra, rebuttal to argument
    against Prop. 57, p. 59.)
    2. Analysis
    The Department contends the ballot materials reveal that
    the voters intended to exclude any inmate currently serving a
    term for a violent felony from early parole consideration,
    regardless of whether such an inmate has also been convicted of
    a nonviolent felony.     The Department stresses that the
    Legislative Analyst stated that the initiative provided for
    “parole consideration for nonviolent offenders.”        (Voter
    Information Guide, Gen. Elec., supra, analysis of Prop. 57 by
    Legis. Analyst, p. 56.) The Department also emphasizes that
    the rebuttal to the arguments opposing Proposition 57
    reiterated that the initiative “Does NOT authorize parole for
    violent offenders” and that “[v]iolent criminals as defined in
    Penal Code 667.5(c) are excluded from parole.”       (Voter
    Information Guide, Gen. Elec., supra, rebuttal to argument
    against Prop. 57, p. 59.)11
    11
    In its briefing before this court, the Department also
    asserted that the number of inmates eligible for early parole
    21
    In re MOHAMMAD
    Opinion of the Court by Cantil-Sakauye, C. J.
    The Department further contends that even if it was not
    compelled to exclude from early parole consideration inmates
    currently serving a term of incarceration for a violent felony, it
    acted within its discretion to do so. In support of this position,
    the Department points to article I, section 32(b), which directs
    the Department to “adopt regulations in furtherance of [the
    constitutional] provisions . . . .” (Art. I, § 32(b).) The exclusion
    of inmates currently serving a term for a violent felony from
    early parole consideration, the Department asserts, reflects its
    reasoned consideration of the policy and public safety
    considerations vested in it by article I, section 32(b), and aligns
    with the intent of the voters as reflected by the ballot materials.
    We agree that the Department acted within the authority
    granted by article I, section 32(b) when it promulgated section
    consideration under the Court of Appeal’s approach — inmates
    convicted only of nonviolent felonies and inmates convicted of
    both    nonviolent   and    violent    felonies —   constituted
    approximately 96 percent of the prison population in 2019. The
    Department contrasted this number with the Legislative
    Analyst’s estimate that 30,000 inmates would receive early
    parole consideration under the initiative.
    Prior to oral argument, however, the Department
    discovered its statistics were erroneous and withdrew its
    arguments related to those statistics. Following oral argument,
    the Department submitted additional data regarding the
    inmate population but did not purport to rely on the new data
    or to otherwise reassert its original argument. Although such
    data may be relevant to interpreting the voters’ intent in some
    contexts, we decline to consider it here given the Attorney
    General’s withdrawal of the argument on this point.
    22
    In re MOHAMMAD
    Opinion of the Court by Cantil-Sakauye, C. J.
    3490, subdivision (a)(5) of the California Code of Regulations.12
    We reach this conclusion based on our consideration of the
    constitutional text, the ballot materials, the stated purposes of
    the initiative, and the Department’s discretion to promulgate
    regulations under the Constitution.          We hold that the
    Department’s regulation is consistent with article I, section 32,
    and is reasonably necessary to effectuate the purpose of
    Proposition 57. (See Morris, supra, 67 Cal.2d at pp. 748–749.)
    Neither the language of the constitutional provision nor
    the materials presented to the voters explicitly stated whether
    an inmate currently serving a term for a violent felony would be
    eligible for parole consideration under the initiative. As we have
    explained, the constitutional text is ambiguous on this point.
    Although the ballot materials do not directly answer the
    question, they conveyed to the voters that Proposition 57 would
    establish “parole consideration for nonviolent offenders” (Voter
    Information Guide, Gen. Elec., supra, analysis of Prop. 57 by
    Legis. Analyst, p. 56) and would not authorize early parole
    consideration for “violent offenders” (Voter Information Guide,
    Gen. Elec., supra, rebuttal to argument against Prop. 57, p. 59).
    As the Department observes, the proponents’ rebuttal
    asserted “violent offenders” and “[v]iolent criminals as defined
    in Penal Code 667.5(c)” would not be eligible for early parole
    consideration. (Voter Information Guide, Gen. Elec., supra,
    rebuttal to argument against Prop. 57, p. 59.) Moreover, the
    ballot materials focus on the distinction between inmates
    convicted of violent felonies and inmates convicted of nonviolent
    12
    In light of this conclusion, we do not address the
    Department’s position that article I, section 32 compels the
    approach the Department adopted in its regulations.
    23
    In re MOHAMMAD
    Opinion of the Court by Cantil-Sakauye, C. J.
    felonies. For this reason, the opponents and proponents sparred
    over the scope of the term nonviolent felony. The proponents
    asserted violent felonies would be defined by Penal Code section
    667.5, subdivision (c) (Voter Information Guide, Gen. Elec.,
    supra, rebuttal to argument against Prop. 57, p. 59), that the
    initiative would “[k]eep[] the most dangerous offenders locked
    up” (id., argument in favor of Prop. 57, p. 58), and that “parole
    eligibility under Prop. 57 applies, ‘only to prisoners convicted of
    non-violent felonies.’    [Brown v. Superior Court, supra,
    63 Cal.4th at p. 352.] Violent criminals as defined in Penal Code
    667.5(c) are excluded from parole” (Voter Information Guide,
    Gen. Elec., supra, rebuttal to argument against Prop. 57, p. 59).
    The opponents’ arguments in the ballot materials did not
    allege that inmates currently serving a term for a violent felony
    offense would be eligible for parole consideration under the
    initiative, or assert the initiative should be rejected for that
    reason. Instead, the thrust of the opponents’ arguments was
    that the scope of the term “violent felony” was too narrow. (See
    Voter Information Guide, Gen. Elec., supra, argument against
    Prop. 57, p. 59.)      The opponents described a number of
    offenses — including certain types of rape, sex trafficking, and
    assault with a deadly weapon — that would be categorized as
    “nonviolent” under the initiative. (Id., rebuttal to argument in
    favor of Prop. 57, p. 58.)
    In this context, Proposition 57 directed the Department to
    “adopt regulations in furtherance of [the constitutional]
    provisions,” and to “certify that these regulations protect and
    enhance public safety.” (Art. I, § 32(b).) In doing so, the
    Department determined that individuals currently serving a
    term of incarceration for a violent felony should be excluded
    from early parole consideration, regardless of whether the
    24
    In re MOHAMMAD
    Opinion of the Court by Cantil-Sakauye, C. J.
    inmate had also been convicted of a nonviolent felony. (See Cal.
    Code. Regs., § 3490, subd. (a)(5).) This approach “reasonably
    interpreted” the Department’s mandate to adopt regulations
    (Woods, supra, 28 Cal.3d at p. 679), is consistent with the
    constitutional language and ballot materials, and is “reasonably
    necessary to effectuate the purpose” of Proposition 57 (Gov.
    Code, § 11342.2).
    The ballot materials support such a conclusion.
    Underlying the debate between the proponents and opponents
    of Proposition 57 was the implication that an inmate serving a
    prison term for a violent felony would be excluded from parole
    consideration. As the Department puts it, “the singular focus on
    ‘nonviolent felonies’ supports the inference that individuals
    serving time for violent felonies would not be eligible.” There
    would be little reason to debate the meaning and scope of the
    term violent felony if having a conviction for a nonviolent felony
    triggered early parole consideration regardless of whether an
    individual was currently serving a term of incarceration for a
    violent felony conviction. The Department’s decision to craft its
    regulations in a way that excluded individuals currently serving
    a term of incarceration for a violent felony is consistent with the
    distinction between violent and nonviolent felonies emphasized
    in the ballot materials.
    Petitioner’s arguments to the contrary are unavailing.
    First, he notes the materials presented to the voters stated that
    “persons convicted of nonviolent felonies” would be eligible for
    parole “upon completion of [a] prison term for their primary
    offense as defined,” but did not indicate that there was an
    exception that would apply if these individuals were currently
    serving a term for a violent felony. (See Voter Information
    Guide, Gen. Elec., supra, Official Title and Summary, p. 54.)
    25
    In re MOHAMMAD
    Opinion of the Court by Cantil-Sakauye, C. J.
    This assertion is premised on the assumption that the phrase
    “any person convicted of a nonviolent felony” in article I, section
    32(a)(1) clearly and unambiguously applies to inmates currently
    serving a term of incarceration for a violent felony conviction —
    a premise we have already rejected above.
    Second, petitioner asserts the ballot materials should not
    be relied on because they are partisan and “may serve to mislead
    a voter about an initiative’s purpose, intent, and effect.” It is
    true that, as we noted in Gadlin, the voters “were explicitly
    warned in the margins of the voter guide that ‘Arguments
    printed on this page are the opinions of the authors, and have
    not been checked for accuracy by any official agency.’ ” (Gadlin,
    supra, 10 Cal.5th at pp. 940–941, quoting Voter Information
    Guide, Gen. Elec., supra, pp. 58, 59.) Still, petitioner provides
    no explanation regarding why any potential partisan bias aids
    him here. He observes that the opponents emphasized the
    initiative would apply to “violent criminals.” (Voter Information
    Guide, Gen. Elec., supra, rebuttal to argument in favor of
    Prop. 57, p. 58, capitalization omitted.) But the opponents’ focus
    on the term “violent criminals,” when taken in context, had
    nothing to do with inmates currently serving a term for a violent
    felony. Rather, the opponents were concerned with the types of
    offenses that would be considered nonviolent under the
    initiative. (See Voter Information Guide, Gen. Elec., supra,
    rebuttal to argument in favor of Prop. 57, p. 58 [asserting
    inmates convicted of crimes including sex trafficking, assault
    with a deadly weapon, lewd acts against a 14-year-old, hostage
    taking, and hate crimes causing injury would be classified as
    nonviolent].) As noted above, neither the proponents nor the
    opponents of Proposition 57 expressly addressed the
    circumstance we consider here. Thus, it cannot be said that the
    26
    In re MOHAMMAD
    Opinion of the Court by Cantil-Sakauye, C. J.
    materials misled the voters with respect to the treatment of
    inmates currently serving a term of incarceration for a violent
    felony, or that the Department acted in excess of its authority
    when crafting the regulation at issue here.
    Petitioner next asserts that the initiative informed the
    voters that the Board of Parole Hearings would guard public
    safety by evaluating each eligible inmate for parole suitability.
    (Voter Information Guide, Gen. Elec., supra, argument in favor
    of Prop. 57, p. 58.) But petitioner does not explain how this
    would have conveyed to the voters an understanding that
    inmates currently serving a term for a violent felony would be
    eligible for early parole consideration.
    Further, petitioner’s reliance on Gadlin with regard to the
    ballot materials is misplaced. In Gadlin, we rejected the
    Department’s position that the ballot materials indicated the
    voters intended to exclude from early parole consideration
    inmates convicted of nonviolent offenses requiring registration
    pursuant to section 290. (Gadlin, supra, 10 Cal.5th at pp. 939–
    940.) We noted that the Department relied on “a single line in
    the proponents’ rebuttal argument” in a manner that “overlooks
    the context of the entire ballot materials provided to the voters.”
    (Id. at p. 939.) Here, by contrast, the ballot materials provide
    much stronger support for the Department’s position than the
    single line on which it relied in Gadlin. As described above, the
    ballot materials consistently contrasted for voters the
    distinction between violent felonies and nonviolent felonies.
    This contrast was further underscored by the analysis of the
    Legislative Analyst, which “assume[d] a nonviolent felony
    offense would include any felony offense that is not specifically
    defined in statute as violent.” (Voter Information Guide, Gen.
    Elec., supra, analysis of Prop. 57 by Legis. Analyst, p. 56.)
    27
    In re MOHAMMAD
    Opinion of the Court by Cantil-Sakauye, C. J.
    Unlike the circumstances in Gadlin, the Department was well
    within its discretion to frame its regulations in light of the
    robust debate captured in the ballot materials.
    Finally, petitioner asserts the voters’ rejection of
    Proposition 20 at the 2020 election constitutes evidence that the
    voters, in passing Proposition 57 in 2016, intended to afford
    parole consideration to inmates serving terms of imprisonment
    for both violent and nonviolent felonies.         He notes that
    Proposition 20 would have explicitly excluded such inmates
    from early parole consideration by adding Penal Code section
    3040.3, subdivision (a) to state: “An inmate whose current
    commitment includes a concurrent, consecutive, or stayed
    sentence for an offense or allegation defined as violent by
    subdivision (c) of Section 667.5 or Section 3040.1 shall be
    deemed a violent offender for purposes of Section 32 of Article I
    of the Constitution.” (Text of Proposed Laws, Gen. Elec. (Nov. 3,
    2020) text of Prop. 20, p. 20.) He asserts that voters’ rejection of
    this “opportunity to override the lower court’s decision in the
    current case” indicates that voters intended Proposition 57 to
    apply to inmates like him who have been convicted of both
    violent and nonviolent felonies.
    Petitioner’s argument is entirely unavailing. A failed
    initiative presented to the voters in 2020 cannot provide
    evidence of the voters’ intent when they cast their ballots in
    2016. (Santa Clara County Local Transportation Authority v.
    Guardino (1995) 
    11 Cal.4th 220
    , 238 [“we cannot speculate that
    the rejection [of an initiative by the voters] amounted to an
    implied approval” of a court opinion that would have been
    effectively overturned by the initiative], citing Dyna-Med, supra,
    43 Cal.3d at p. 1396; In re Guice, supra, 66 Cal.App.5th at p. 942
    28
    In re MOHAMMAD
    Opinion of the Court by Cantil-Sakauye, C. J.
    [“There is simply no way of knowing why voters rejected
    Proposition 20 four years after they approved Proposition 57”].)
    We therefore conclude that the Department acted within
    its discretion when it promulgated section 3490, subdivision
    (a)(5) of the California Code of Regulations excluding
    individuals currently serving a sentence for a violent felony from
    early parole consideration. This conclusion, however, is not a
    determination that the Department’s regulation is the most
    plausible of the various interpretations offered. Because the
    Department is vested with the authority to adopt regulations in
    this context, we need only conclude that its regulation is a valid
    exercise of its rulemaking authority.
    As to the application of the regulation to this case,
    petitioner does not contest the Department’s determination that
    he is currently serving a term of incarceration for a violent
    felony. As described, petitioner was convicted of nine counts of
    second degree robbery (a violent felony), six counts of receiving
    stolen property (a nonviolent felony), and various gang
    enhancements. His only argument before this court is that he
    should be entitled to early parole consideration because he is a
    “mixed-offense prisoner whose nonviolent felony offense is his
    primary offense and whose violent offenses are secondary ones
    that run consecutive and subordinate to that primary and
    principal offense.” Because petitioner has not contested the
    Department’s determination that he is currently serving a term
    for a violent felony, and because we have determined that the
    regulation excluding from early parole consideration inmates
    who are currently serving a term for a violent felony is a valid
    exercise of the Department’s rulemaking authority under
    article I, section 32(b), we conclude the Department’s denial of
    29
    In re MOHAMMAD
    Opinion of the Court by Cantil-Sakauye, C. J.
    petitioner’s request      for   early   parole     consideration   was
    permissible.13
    III. CONCLUSION
    Neither the language of article I, section 32(a)(1) of the
    California Constitution nor the ballot materials presented to the
    voters speak directly to whether inmates with nonviolent felony
    convictions who are currently serving a term for a violent felony
    must be considered for early parole suitability. Against this
    backdrop, and the direction in article I, section 32(b) to
    promulgate regulations, the Department determined that
    inmates serving a term of incarceration for a violent felony
    should be excluded from early parole consideration. (Cal. Code
    Regs., § 3490, subd. (a)(5).) The Department’s approach is
    consistent with a reasonable interpretation of the constitutional
    language and the ballot materials. We cannot say that the
    Department abused its rulemaking authority in coming to this
    conclusion.
    13
    The concurring opinion in Douglas agreed that the
    petitioner there was “still serving a sentence for a violent felony
    offense” and thus was ineligible for early parole consideration at
    the time he sought it. (Douglas, supra, 62 Cal.App.5th at p. 739
    (conc. opn. of Robie, Acting P. J.).) The concurring opinion
    further asserted that article I, section 32(a)(1)(A) required the
    court to “break an inmate’s sentence into its component parts
    for the purpose of determining whether that inmate has served
    his or her primary offense, making the particular sequence in
    which an inmate serves his or her violent offense a meaningful
    abstraction.” (Id. at p. 738.) Because petitioner here does not
    contest that he is currently serving a term of incarceration for a
    violent felony, we are not presented with the issue of whether
    article I, section 32 requires us to break an inmate’s sentence
    into its component parts. We express no view on that issue or
    on the approach adopted by the concurring opinion in Douglas.

    In re MOHAMMAD
    S259999
    Concurring Opinion by Justice Liu
    The Public Safety and Rehabilitation Act of 2016, known
    as Proposition 57, provides that “[a]ny person convicted of a
    nonviolent felony offense . . . shall be eligible for parole
    consideration after completing the full term for his or her
    primary offense.” (Cal. Const., art. I, § 32, subd. (a)(1) (article I,
    section 32(a)(1)).) To implement this provision, the Department
    of Corrections and Rehabilitation (Department) adopted a
    regulation that makes ineligible for early parole consideration
    any inmate who is “currently serving a term of incarceration for
    a ‘violent felony.’ ” (Cal. Code Regs., tit. 15, § 3490, subd. (a)(5).)
    For the reasons stated in today’s opinion, I agree that this
    regulation, as written, is a reasonable construction of article I,
    section 32(a)(1).
    Lurking beneath this holding, however, are a number of
    questions concerning what it means for an inmate with both
    violent and nonviolent felony convictions to be “currently
    serving a term of incarceration for a ‘violent felony.’ ” (Cal. Code
    Regs., tit. 15, § 3490, subd. (a)(5).) But because petitioner
    Mohammad Mohammad has not contested the Department’s
    determination that he is currently serving a term for a violent
    felony, we have no occasion here to examine the proper
    application of the regulation to inmates like Mohammad who
    are incarcerated for both violent and nonviolent felony offenses.
    (Maj. opn., ante, at pp. 29–30 & fn. 13.)
    Mohammad was sentenced to a consecutive term of 29
    years for multiple violent (robbery) and nonviolent (receiving
    In re MOHAMMAD
    Liu, J., concurring
    stolen property) offenses. In its administrative review of his
    request for early parole consideration, the Department
    determined that his robbery offense (any one of them) “ ‘makes
    all of his offenses to be considered violent during this term.’ ”
    (In re Mohammad (2019) 
    42 Cal.App.5th 719
    , 724.) In In re
    Reeves (2005) 
    35 Cal.4th 765
    , 772, we said that “[u]nder the
    Determinate Sentencing Act ([Pen. Code,] § 1170 et seq.),
    multiple consecutive determinate terms must be combined into
    a single, ‘aggregate term of imprisonment for all [such]
    convictions’ ([id.,] § 1170.1, subd. (a)) that merges all terms to
    be served consecutively . . . .”     The Department seems to
    contemplate that the merger of consecutive terms into a single
    aggregate term means that an inmate serving a consecutive
    sentence for violent and nonviolent felony convictions is
    “currently serving a term of incarceration for a ‘violent felony’ ”
    (Cal. Code Regs., tit. 15, § 3490, subd. (a)(5)) throughout the
    entire duration of the consecutive sentence.
    But there is some tension between the Department’s view
    and Proposition 57’s definition of “primary offense” to mean “the
    longest term of imprisonment imposed by the court for any
    offense, excluding the imposition of an enhancement,
    consecutive sentence, or alternative sentence.”          (Art. I,
    § 32(a)(1)(A), italics added.) As Justice Robie explained in In re
    Douglas (2021) 
    62 Cal.App.5th 726
    , this language seems to
    “require[ ] us to break an inmate’s sentence into its component
    parts,” notwithstanding the merger rule, in order to determine
    what term the inmate is currently serving at the time he or she
    seeks early parole consideration. (Id. at p. 738 (conc. opn. of
    Robie, Acting P. J.); see art. I, § 32(a) [“The following provisions
    are hereby enacted . . . notwithstanding anything in this article
    or any other provision of law . . . .”].)
    2
    In re MOHAMMAD
    Liu, J., concurring
    Consider, for example, an inmate serving a consecutive
    sentence for a robbery offense with a six-year term and a
    receiving stolen property offense with a three-year term. The
    robbery offense is the “primary offense” because it carries “the
    longest term of imprisonment imposed by the court for any
    offense.” (Art. I, § 32(a)(1)(A).) Once the inmate has completed
    the six-year term for his primary offense of robbery, is he then —
    for purposes of article I, section 32(a)(1) — currently serving a
    term for the nonviolent offense of receiving stolen property and
    thus eligible for early parole consideration, as Justice Robie’s
    view suggests? Or does article I, section 32(a)(1) allow the
    Department to treat him as currently serving a term for the
    violent offense throughout the entire nine-year aggregate
    sentence and find him ineligible for early parole consideration
    on that basis?
    Today’s decision does not answer these questions, nor does
    it address at what point, if any, during Mohammad’s consecutive
    sentence he may become eligible for early parole consideration.
    These issues await resolution in future cases.
