    Defendants and                           OPINION; NO CHANGE
    Appellants;                                   IN JUDGMENT

    et al.,
    Interveners and
    Appellants.
    THE COURT*:
    The concurrence and dissent to this opinion filed on
    March 13, 2023, is modified as follows:
    1. On page 18 of the concurrence and dissent, in
    second full paragraph (which begins: “The
    deficiency I see here is structural.”), in the last
    sentence of text, change the state constitutional
    *Brown, P. J., Streeter, J., Pollak, J. (Retired Presiding
    Justice of the Court of Appeal, First Appellate District, Division
    Four, assigned by the Chief Justice pursuant to article VI,
    section 6 of the California Constitution).
    1
    reference at the end of that sentence from “article
    XIV, section 4” to “article XII, section 5” so the
    sentence reads:
    Because voter “electors” and the “Legislature”
    share the police power, they may each legislate
    on the subject of workers’ compensation, which is
    why our Supreme Court has held that the
    article II, section 8(a) power to adopt initiative
    statutes is “encompass[ed]” within the
    Legislature’s article XII, section 5 power.
    2. On page 20 of the concurrence and dissent, in the
    partial paragraph at the top of the page, delete the
    phrase “workers’ compensation matters” and insert
    in its place the phrase “matters falling within the
    scope of that provision” so that it reads:
    pointed out that the electors’ ability to adopt
    statutes by initiative is a “similar power” to that
    of the Legislature under article XII, section 5
    (McPherson, supra, 38 Cal.4th at p. 1033), not
    that the electors are “the Legislature” when they
    legislate on matters falling within the scope of
    that provision, having simply stepped into the
    shoes of the Legislature, clothed with article XII,
    section 5, authority.
    3. On page 43 of the concurrence and dissent, in the
    first full paragraph (which begins: “Disagreeing
    with me on this point, . . .”), in the last sentence of
    text, change the word “appeared” to “appears” so
    that it reads:
    Nor do these cases give any reason for why the
    binding effect clause should be read as an
    implicit partial definition of “employer,” a term
    that appears nowhere in the constitutional
    language and was already fully defined in the
    statutory scheme the voters ratified in 1918.
    The modifications effect no change in the judgment.

    In November 2020, the voters approved Proposition 22, the
    Protect App-Based Drivers and Services Act (Proposition 22).
    (Bus. & Prof. Code, 1 §§ 7448–7467, as added by Prop. 22,
    approved by the voters at Gen. Elec. (Nov. 3, 2020).) Shortly

    California State Council, and Service Employees International
    Union (SEIU; collectively, plaintiffs) filed a petition for writ of
    mandate seeking a declaration that Proposition 22 is invalid
    because it violates the California Constitution.2 The trial court
    granted the petition, ruling that the proposition (1) is invalid in
    its entirety because it intrudes on the Legislature’s exclusive
    authority to create workers’ compensation laws; (2) is invalid to
    the extent that it limits the Legislature’s authority to enact
    legislation that would not constitute an amendment to
    Proposition 22, and (3) is invalid in its entirety because it violates
    the single-subject rule for initiative statutes.
    Proposition 22’s proponents and the state appeal, arguing
    the trial court was mistaken on all three points. We agree that
    Proposition 22 does not intrude on the Legislature’s workers’
    compensation authority or violate the single-subject rule, but we
    conclude that the initiative’s definition of what constitutes an
    amendment violates separation of powers principles. Because the
    unconstitutional provisions can be severed from the rest of the
    initiative, we affirm the judgment insofar as it declares those
    provisions invalid and to the extent the trial court retained
    jurisdiction to consider an award of attorney’s fees, and otherwise
    reverse.
    BACKGROUND
    In 2019, the Legislature enacted Assembly Bill No. 5
    (2019–2020 Reg. Sess.), which established a new test for
    2Undesignated citations to constitutional articles and
    sections are to the California Constitution.

    distinguishing between employees and independent contractors
    for the purposes of the Labor Code and Unemployment Insurance
    Code. (Stats. 2019, ch. 296; Lab. Code, § 2775, subd. (b)(1);
    People v. Uber Technologies, Inc. (2020) 
    56 Cal.App.5th 266
    , 274–
    277 [describing background of statute].)
    In response, Davis White and Keith Yandell, supported by
    a group called Protect App-Based Drivers and Services (Protect
    Drivers; collectively, interveners), proposed Proposition 22.
    (§ 7449, subd. (d).) An “[a]pp-based driver” is a person who works
    as a driver or courier for transportation or delivery network
    companies, which are businesses that operate transportation or
    delivery services using an electronic application or platform to
    connect passengers seeking transportation or customers seeking
    delivery of goods to drivers or couriers willing to provide those
    services with their personal vehicles. (§ 7463, subds. (a), (f), (i),
    (q).) Among the supporters of Protect Drivers and Proposition 22
    were rideshare and delivery network companies such as Uber
    Technologies, Inc., Lyft, Inc., and DoorDash, Inc.
    When interveners requested a title and summary of the
    measure so they could gather the necessary signatures to qualify
    it for the ballot, the Attorney General gave it the title “Changes
    Employment Classification Rules for App-Based Transportation
    and Delivery Drivers.” The Attorney General later modified the
    title for the purposes of the voter information guide, titling it
    “Exempts App-Based Transportation and Delivery Companies
    from Providing Employee Benefits to Certain Drivers.” (Voter
    Information Guide, Gen. Elec. (Nov. 3, 2020) title and summary
    3
    of Prop. 22, p. 56 (Voter Guide).) White and Protect Drivers filed
    a petition for writ of mandate in Sacramento County Superior
    Court to compel the Attorney General to revise the title and
    summary, but that court denied the petition.
    Proposition 22 added sections 7448 to 7467 to the Business
    and Professions Code. (Proposition 22, § 1, available at
     [as of
    Mar. 13, 2023].) Section 7450 states the initiative’s purposes are
    to (1) “protect the basic legal right of Californians to choose to
    work as independent contractors with rideshare and delivery
    network companies”; (2) “protect the individual right of every
    app-based rideshare and delivery driver to have the flexibility to
    set their own hours for when, where, and how they work”;
    (3) “require rideshare and delivery network companies to offer
    new protections and benefits for app-based rideshare and
    delivery drivers”; and (4) “improve public safety by requiring
    criminal background checks, driver safety training, and other
    safety provisions to help ensure app-based rideshare and delivery
    drivers do not pose a threat to customers or the public.” (§ 7450.)
    To achieve these purposes, section 7451, titled “Protecting
    Independence,” provides, “Notwithstanding any other provision of
    law, including, but not limited to, the Labor Code, the
    Unemployment Insurance Code, and any orders, regulations, or
    opinions of the Department of Industrial Relations or any board,
    division, or commission within the Department of Industrial
    Relations, an app-based driver is an independent contractor and
    not an employee or agent with respect to the app-based driver’s
    4
    relationship with a network company” if the company does not
    control the drivers in certain specified ways. (§ 7451.)3
    Proposition 22 then details certain benefits to which drivers are
    entitled, including a health care subsidy for drivers meeting
    certain minimum requirements for hours spent providing services
    (as opposed to waiting to provide services); a minimum earnings
    guarantee based on time spent providing services; occupational
    accident insurance; and contract, anti-discrimination, and
    termination rights. (§§ 7452–7456, 7463, subd. (j).) The
    initiative also includes various obligations for drivers relating to
    safety, such as background check and rest requirements.
    (§§ 7458, 7461.)
    Section 7465 is the only section contained in article 9,
    which is titled “Amendment”; it describes the circumstances in
    which the Legislature can amend Proposition 22 without voter
    approval. (§ 7465.) As relevant here, section 7465 states that the
    3 The specific conditions section 7451 imposes for an app-
    based driver to qualify as an independent contractor are:
    “(a) The network company does not unilaterally prescribe specific
    dates, times of day, or a minimum number of hours during which
    the app-based driver must be logged into the network company’s
    online-enabled application or platform. [¶] (b) The network
    company does not require the app-based driver to accept any
    specific rideshare service or delivery service request as a
    condition of maintaining access to the network company’s online-
    enabled application or platform. [¶] (c) The network company
    does not restrict the app-based driver from performing rideshare
    services or delivery services through other network companies
    except during engaged time. [¶] (d) The network company does
    not restrict the app-based driver from working in any other
    lawful occupation or business.”
    5
    Legislature can amend Proposition 22’s provisions with a statute
    passed by a seven-eighths majority in both houses, so long as the
    statute is “consistent with, and furthers the purpose of,” the
    initiative and the Legislature complies with certain procedural
    requirements. (§ 7465, subd. (a).) Section 7465, subdivision (c)
    (section 7465(c)) then addresses the application of these
    requirements. Section 7465(c)(1) states that the initiative’s
    purposes are described in sections 7448 to 7450. Section
    7465(c)(2) states that any statute that amends the definition of
    app-based drivers as independent contractors in section 7451
    does not further those purposes, effectively preventing the
    Legislature from amending that section without voter approval.
    Section 7465(c)(3) declares that any statute that places unequal
    regulatory burdens on app-based drivers, such as a rule that
    prohibits only app-based drivers from performing particular
    services, constitutes an amendment of the initiative. And section
    7465(c)(4) declares that a statute constitutes an amendment if it
    “authorizes any entity or organization to represent the interests
    of app-based drivers in connection with drivers’ contractual
    relationships with network companies, or drivers’ compensation,
    benefits, or working conditions.”
    Proposition 22 contains a severability clause declaring that
    if any provision is held to be invalid, the remainder of the
    initiative shall remain valid, except that the invalidity of
    anything in section 7451—which declares drivers to be
    independent contractors and not employees under certain
    conditions—would invalidate the entire initiative. (§ 7467.)
    6
    The voters approved Proposition 22 in November 2020,
    with 58.6 percent of voters in favor and 41.4 percent opposed.
    In January 2021, plaintiffs filed a petition for writ of
    mandate in the California Supreme Court seeking a declaration
    that Proposition 22 is invalid. The Supreme Court denied the
    petition in February 2021 “without prejudice to refiling in an
    appropriate court,” though two justices were of the opinion that
    the court should have issued an order to show cause.
    (Castellanos v. State of California, S266551, Supreme Ct. Mins.,
    Feb. 3, 2021.)
    A week later, plaintiffs filed a petition for writ of mandate
    in Alameda County Superior Court. Plaintiffs named as
    defendants the State of California and Katie Hagen as the
    director of the Department of Industrial Relations (defendants).
    By stipulation, the trial court granted interveners leave to
    intervene to oppose the petition as real parties in interest.
    Plaintiffs alleged that Proposition 22 is invalid for four
    reasons. First, they argued it improperly limits the Legislature’s
    authority in article XIV, section 4 of the California Constitution
    to create a workers’ compensation system.4 Second, plaintiffs
    alleged that Proposition 22’s provision defining what types of
    4 The provision was originally found in article XX,
    section 21. (See Mathews v. Workmen’s Comp. Appeals Bd. (1972)
    
    6 Cal.3d 719
    , 724, fn. 2, 734 (Mathews).) It was renumbered in a
    constitutional reorganization in 1976, without substantive
    change. (See Pacific Legal Foundation v. Brown (1981) 
    29 Cal.3d 168
    , 184, fn. 8; Ballot Pamp., Prim. Elec. (June 8, 1976)
    pp. 58–59.) For simplicity, we refer to this provision using its
    current numbering, regardless of the time period at issue.
    7
    statutes would constitute amendments to the initiative violates
    the separation of powers doctrine because it restricts the courts’
    authority to interpret the Constitution. Third, they alleged that
    the amendment provision violates the separation of powers
    because it attempts to prevent the Legislature from enacting
    laws on matters not substantively addressed within the measure.
    Fourth, plaintiffs alleged that one aspect of the amendment
    provision violates the rule in article II, section 8 of the
    Constitution limiting initiatives to a single subject because it
    imposes restrictions on subjects not substantively addressed in
    the initiative and it deceived voters into adopting restrictions
    that they did not understand.
    In August 2021, the trial court agreed with plaintiffs’ first,
    third, and fourth arguments. It issued a judgment in September
    2021 declaring Proposition 22 invalid in its entirety and ordering
    Hagen, as director of the Department of Industrial Relations, not
    to enforce any of Proposition 22’s provisions.
    DISCUSSION
    I.   General Legal Principles and Standard of Review
    The trial court’s ruling that Proposition 22 is
    unconstitutional turns on the interplay between the language of
    Proposition 22 and constitutional provisions governing workers’
    compensation law, the initiative power, and the separation of
    powers. “We apply similar principles when construing
    constitutional provisions and statutes, including those enacted
    through voter initiative. [Citation.] Our primary concern is
    giving effect to the intended purpose of the provisions at issue.
    8
    [Citation.] In doing so, we first analyze provisions’ text in their
    relevant context, which is typically the best and most reliable
    indicator of purpose. [Citations.] We start by ascribing to words
    their ordinary meaning, while taking account of related
    provisions and the structure of the relevant statutory and
    constitutional scheme. [Citations.] If the provisions’ intended
    purpose nonetheless remains opaque, we may consider extrinsic
    sources, such as an initiative’s ballot materials. [Citation.]
    Moreover, when construing initiatives, we generally presume
    electors are aware of existing law. [Citation.] Finally, we apply
    independent judgment when construing constitutional and
    statutory provisions.” (California Cannabis Coalition v. City of
    Upland (2017) 
    3 Cal.5th 924
    , 933–934.)
    “ ‘[T]he Constitution’s initiative and referendum provisions
    should be liberally construed to maintain maximum power in the
    people.’ ” (Independent Energy Producers Assn. v. McPherson
    (2006) 
    38 Cal.4th 1020
    , 1032 (McPherson).) The Supreme Court
    has declared it the courts’ “ ‘solemn duty to jealously guard the
    precious initiative power, and to resolve any reasonable doubts in
    favor of its exercise.’ ” (Briggs v. Brown (2017) 
    3 Cal.5th 808
    , 827
    (Briggs).) “ ‘ “We do not consider or weigh the economic or social
    wisdom or general propriety of the initiative. Rather, our sole
    function is to evaluate [it] legally in the light of established
    constitutional standards.” ’ [Citations.] ‘ “[A]ll presumptions and
    intendments favor the validity of a statute and mere doubt does
    not afford sufficient reason for a judicial declaration of invalidity.
    Statutes must be upheld unless their unconstitutionality clearly,
    9
    positively, and unmistakably appears.” [Citations.] If the
    validity of the measure is “fairly debatable,” it must be
    sustained.’ ” (Id. at p. 828.)
    “We consider only the objections raised by the [case] before
    us. ‘We have no occasion at this time to consider other possible
    attacks,’ and ‘except as necessary to resolve the basic questions
    before us, we do not consider in this case possible interpretive or
    analytical problems’ that might arise from the measure in the
    future.” (Briggs, 
    supra,
     3 Cal.5th at p. 827.) We review here a
    facial challenge to the constitutionality of Proposition 22, and we
    express no view on claims that might be asserted in specific
    applications of the initiative.
    II. Article XIV, Section 4 of the California Constitution
    Article XIV, section 4 of the California Constitution begins,
    “The Legislature is hereby expressly vested with plenary power,
    unlimited by any provision of this Constitution, to create, and
    enforce a complete system of workers’ compensation, by
    appropriate legislation, and in that behalf to create and enforce a
    liability on the part of any or all persons to compensate any or all
    of their workers for injury or disability, and their dependents for
    death incurred or sustained by the said workers in the course of
    their employment, irrespective of the fault of any party.” (Cal.
    Const., art. XIV, § 4.)5
    The trial court’s ruling based on this provision is
    straightforward. Article II, section 10, subdivision (c) (Cal.
    5Additional portions of article XIV, section 4 are quoted in
    other parts of this opinion. (See, e.g., fn. 11 and pp. 26–28, post.)
    10
    Const., art. II, § 10(c)) allows the Legislature to amend an
    initiative statute only if the voters approve the amendment,
    unless the initiative permits amendment without voters’
    approval, in which case the Legislature must comply with any
    conditions the voters impose.6 Because of this authority, the
    Legislature cannot amend or repeal section 7451 at all to classify
    app-based drivers as employees for the purposes of workers’
    compensation or amend the initiative in any other respect
    without a seven-eighths majority or the approval of the voters.
    The trial court concluded these restrictions on the Legislature are
    contrary to article XIV, section 4’s statement that the
    Legislature’s power to create a workers’ compensation system is
    “plenary” and “unlimited by any provision of this Constitution.”
    The trial court pointed out that the voters added the phrase
    “unlimited by any provision of this Constitution” to article XIV,
    section 4, in a constitutional amendment in 1918, seven years
    after they amended the Constitution to allow for voter initiatives.
    It concluded the plain meaning of article XIV, section 4 prevailed
    over the more general provision in article II, section 10(c).
    Finally, because Proposition 22 states that any invalidation of
    section 7451 invalidates the entire initiative, the trial court found
    the constitutional conflict renders Proposition 22 invalid in its
    entirety.
    6Article II, section 10(c) states in pertinent part, “The
    Legislature may amend or repeal an initiative statute by another
    statute that becomes effective only when approved by the electors
    unless the initiative statute permits amendment or repeal
    without the electors’ approval.”
    11
    The Supreme Court’s decision in McPherson, 
    supra,
    38 Cal.4th 1020
    , which involved a provision worded similarly to
    article XIV, section 4, is contrary to the trial court’s ruling, so we
    discuss it in some detail. At issue there was article XII, section 5,
    which states, “The Legislature has plenary power, unlimited by
    the other provisions of this constitution but consistent with this
    article, to confer additional authority and jurisdiction upon the
    [Public Utilities Commission (PUC)], to establish the manner and
    scope of review of commission action in a court of record, and to
    enable it to fix just compensation for utility property taken by
    eminent domain.” (McPherson, at p. 1032.) An initiative statute
    would have expanded the PUC’s authority over electric service
    providers. (Id. at p. 1026.) Opponents of the initiative argued
    that the initiative statute violated the Legislature’s exclusive
    authority to expand the PUC’s authority. (Id. at p. 1027.)
    The Court of Appeal held that this constitutional provision
    was clear and unambiguous and dictated that only the
    Legislature could confer additional authority on the PUC, not the
    voters. (McPherson, supra, 38 Cal.4th at p. 1032.) The Court of
    Appeal recognized that courts had previously held that references
    in the Constitution to the Legislature having a power did not
    deprive the voters of their initiative power. (McPherson, at
    pp. 1033–1035.) But the Court of Appeal found those cases
    distinguishable because article XII, section 5 gave the Legislature
    “plenary” power that was “ ‘unlimited by the other provisions of
    this constitution.’ ” (McPherson, at p. 1035.)
    12
    Before the Supreme Court, the proponents of the initiative
    challenged the Court of Appeal’s reasoning by pointing out that a
    “plenary power” is complete but is not necessarily exclusive.
    (McPherson, supra, 38 Cal.4th at p. 1035.) They also noted that
    the Court of Appeal’s broad interpretation of the “unlimited”
    clause logically would have meant “that a statute passed by the
    Legislature pursuant to article XII, section 5 would not be subject
    to any provision of the California Constitution, including, for
    example, the provision authorizing the Governor to veto a bill
    approved by the Legislature.” (Id. at p. 1036.) The Supreme
    Court agreed that these arguments showed that article XII,
    section 5 was not unambiguous, “[p]articularly in light of the
    numerous past California authorities holding that constitutional
    references to the Legislature’s authority to take specified action
    generally are not interpreted to limit the initiative power.”
    (McPherson, at p. 1036.) The court therefore considered the
    origin and background of the constitutional language. (Id. at
    pp. 1036–1037.) The voters had added the language to the
    Constitution in 1911, the same year as the initiative power.
    (McPherson, at pp. 1037–1041.) Because both the initiative
    power and the language allowing the Legislature to expand the
    authority of the PUC were part of the reform program of the
    progressive movement, the court found it “most improbable” that
    the voters intended the amendment to article XII, section 5 to
    limit the scope of the initiative power they approved
    simultaneously, “without any direct or explicit statement to this
    effect.” (McPherson, at p. 1042.)
    13
    McPherson reveals two flaws in the trial court’s ruling.
    First, McPherson expressly approved “long-standing California
    decisions establishing that references in the California
    Constitution to the authority of the Legislature to enact specified
    legislation generally are interpreted to include the people’s
    reserved right to legislate through the initiative power.”
    (McPherson, supra, 38 Cal.4th at p. 1043.) This principle—which
    plaintiffs do not dispute—deprives the trial court’s textual
    argument of much of its force. Rather than read article XIV,
    section 4 as conferring plenary, unlimited power on the
    Legislature and only the Legislature, McPherson requires that
    we read article XIV, section 4 as though it said, “The Legislature
    or the electorate acting through the initiative power are hereby
    expressly vested with plenary power, unlimited by any provision
    of this constitution, to create, and enforce a complete system of
    workers’ compensation . . . .” (See McPherson, 
    supra,
     38 Cal.4th
    at pp. 1032 [“ ‘the power of the people [to enact statutes] through
    the statutory initiative is coextensive with the power of the
    Legislature’ ”], 1033, 1042–1043 [reading article XII, section 5 as
    though it referred to the electorate’s initiative power].)7
    7 This aspect of McPherson answers the contention
    underlying much of the dissenting opinion that article XIV,
    section 4 delegates power specifically to the Legislature and not
    the voters. (Conc. & dis. opn., post, at p. 30.) The dissenting
    opinion’s view rests primarily on the fact that article XIV, section
    4 is not self-executing. (Conc. & dis. opn., post, at pp. 30–31.)
    There is no logical conflict between article XIV, section 4 needing
    implementing legislation and the voters retaining their initiative
    power in the same field; both can coexist.
    14
    Given that article XIV, section 4 must be construed to grant
    lawmaking authority to both the Legislature and the electorate,
    it is not significant that article XIV, section 4 confers plenary
    power, nor that the people may exercise their initiative power in
    a way that limits the Legislature’s authority under article XIV,
    section 4. Article XIV, section 4 is not concerned with the
    allocation of power between the Legislature and the electorate,
    but rather with ensuring that the lawmaking bodies jointly and
    severally have authority to create a workers’ compensation
    system. If the people enact an initiative statute to create or
    modify the workers’ compensation system, they have exercised
    the plenary, unlimited authority that article XIV, section 4
    confers and satisfied that aspect of the Constitution. As courts
    must liberally construe the initiative power and resolve doubts in
    favor of the use of the initiative wherever reasonable, this is the
    interpretation of article XIV, section 4 that we must adopt.
    (Briggs, supra, 3 Cal.5th at pp. 827–828.)
    Second, McPherson shows that the trial court erred when it
    read article XIV, section 4 as a plain statement prevailing over
    the initiative power and that plaintiffs likewise err when reading
    it as an express repeal of the initiative power. McPherson held
    that nearly identical language regarding the Legislature’s power
    vis à vis the PUC was “at most ambiguous.” (McPherson, supra,
    38 Cal.4th at p. 1025.) It reached that conclusion in part based
    on its reasoning that applying the “unlimited” language literally
    would mean that the Legislature could enact a law without
    having to comply with provisions of the Constitution like the one
    15
    that gives the Governor the right to veto legislation. (McPherson,
    at p. 1036.)
    The same rationale applies here. Since article XIV,
    section 4’s “unlimited” clause cannot mean that workers’
    compensation laws are exempt from every other aspect of the
    Constitution, it is ambiguous as to which aspects of the
    Constitution continue to apply and which do not. As in
    McPherson, this finding of ambiguity would require us to consult
    the ballot materials from the election in 1918 at which the voters
    added the “unlimited” language to article XIV, section 4, in order
    to discern the intent behind it. The initiative power was already
    part of the Constitution at that time, as the trial court noted.
    But the Supreme Court has already concluded that the history of
    article XIV, section 4 shows the provision “was added to the
    Constitution and then amended for the sole purpose of removing
    all doubts as to the constitutionality of the then existing
    workmen’s compensation statutes.” (Mathews, supra, 6 Cal.3d at
    pp. 734–735, italics added.)8 Plaintiffs cite no authority or
    8 The dissenting opinion cites Mathews, supra, 6 Cal.3d at
    page 735, as supporting its theory that neither the Legislature
    nor the electorate can change any of the basic features of the pre-
    1918 workers’ compensation system. (Conc. & dis. opn., post, at
    p. 6.) The point of Mathews was only that article XIV, section 4
    was intended to authorize the workers’ compensation system that
    already existed—not that those features became sacrosanct and
    untouchable by either the Legislature or the electorate. (City and
    County of San Francisco v. Workers’ Comp. Appeals Bd. (1978)
    
    22 Cal.3d 103
    , 114 [article XIV, § 4’s purpose “was simply to
    remove any doubt as to the constitutionality of the existing
    workers’ compensation legislation, and not to erect any new
    16
    evidence indicating to the contrary that article II, sections 8 and
    10 and article IV, section 1—relating to the initiative power—
    were provisions from which the voters intended to free the
    Legislature when enacting workers’ compensation laws. Absent
    such evidence, the notion that article XIV, section 4 should be
    read as limiting the voters’ initiative power falls apart.9 To
    restrictions on the exercise of legislative power,” (citing Mathews,
    at pp. 733–734, fn. 11, italics added)].) Because article XIV,
    section 4’s purpose was to ensure that the workers’ compensation
    system was “ ‘beyond the possibility of being attacked on
    technical grounds or by reason of any questioned want of
    constitutional authority,’ ” Mathews rejected a constitutional
    challenge to the Legislature’s enactment of an amendment to the
    workers’ compensation scheme that expanded on a pre-1918 type
    of exclusion from coverage. (Mathews, supra, 6 Cal.3d at p. 735 &
    fn. 11, italics omitted.) Nothing in Mathews suggests that article
    XIV, section 4 prevents the Legislature from changing workers’
    compensation in any ways it sees fit, which is unsurprising given
    its grant of plenary authority to create a system requiring “any or
    all persons to compensate any or all of their workers.” (Cal.
    Const., art. XIV, § 4, italics added.) The dissenting opinion
    disregards this language as merely confirming that the
    Legislature had not yet covered all potentially eligible workers,
    but that is precisely the point: it gives the Legislature the
    authority to change coverage if it chooses. (Conc. & dis. opn.,
    post, at p. 56.) Notably, even plaintiffs agree that it has this
    authority, since they admit the Legislature could have excluded
    app-based drivers from workers’ compensation coverage.
    9 Interveners ask us to judicially notice two sections from a
    treatise describing the history and purpose of article XIV,
    section 4 of the Constitution, as well as a 1918 newspaper
    editorial discussing the initiative that amended this provision.
    Relatedly, amicus curiae California Constitution Center seeks
    judicial notice of a host of news articles concerning the 1911 and
    1918 propositions that created and amended article XIV, section
    4. We deny these requests as unnecessary. (County of San Diego
    17
    paraphrase McPherson, it is “most improbable” that the voters in
    1918—seven years after they “approved a far-reaching measure
    incorporating a broad initiative power as part of the California
    Constitution”—would have intended, “without any direct or
    explicit statement to this effect, to limit the use of the initiative
    power by virtue of the language” in article XIV, section 4.
    (McPherson, supra, 38 Cal.4th at p. 1042.)
    Plaintiffs do not agree that McPherson controls here. Like
    the trial court, they rely on footnote 9 of that decision, where the
    Supreme Court “emphasize[d]” that its holding was “limited to a
    determination that the provisions of article XII, section 5 do not
    preclude the use of the initiative process to enact statutes
    conferring additional authority upon the PUC.” (McPherson,
    supra, 38 Cal.4th at p. 1044, fn. 9.) The court continued, “We
    have no occasion in this case to consider whether an initiative
    measure relating to the PUC may be challenged on the ground
    that it improperly limits the PUC’s authority or improperly
    conflicts with the Legislature’s exercise of its authority to expand
    the PUC’s jurisdiction or authority. Should these or other issues
    arise in the future, they may be resolved through application of
    the relevant constitutional provision or provisions to the terms of
    the specific legislation at issue.” (Ibid., second italics added.)
    Plaintiffs assert that their challenge to Proposition 22
    raises the type of conflict that McPherson foresaw and about
    which it reserved judgment, since they contend Proposition 22
    v. State of California (2008) 
    164 Cal.App.4th 580
    , 613, fn. 29
    [denying request for judicial notice as unnecessary].)
    18
    improperly conflicts with the Legislature’s exercise of its
    authority to enact workers’ compensation laws. Moreover,
    according to plaintiffs, applying McPherson’s logic to decide that
    a voter initiative relating to workers’ compensation can conflict
    with the Legislature’s authority under article XIV, section 4
    would be contrary to McPherson’s instruction that a challenge to
    the Legislature’s plenary, unlimited power under article XII,
    section 5 should be resolved “through application of the relevant
    constitutional provision or provisions to the terms of the specific
    legislation at issue.” (McPherson, supra, 38 Cal.4th at p. 1044,
    fn. 9.) According to plaintiffs, there would have been no reason
    for our Supreme Court to include this footnote if a voter initiative
    can always undo what the Legislature does with plenary,
    unlimited power, like that which article XIV, section 4 provides.
    We do not read McPherson’s footnote 9 as broadly as
    plaintiffs or the trial court. That footnote states only that the
    court had “no occasion” to address a challenge like the one in this
    case, meaning the court was not resolving such challenges either
    way. (McPherson, supra, 38 Cal.4th at p. 1044, fn. 9.) The
    court’s generalized instruction to resolve such challenges
    “through application of the relevant constitutional provision or
    provisions to the terms of the specific legislation at issue” did not
    imply that the principles it had enunciated and applied in
    McPherson would have no bearing on such challenges. (Ibid.)
    The McPherson court may have wanted to leave open, as a
    precedential matter, the possibility that an argument could be
    made that an initiative statute improperly limited the
    19
    Legislature’s authority in some fashion. But plaintiffs have
    failed to offer any argument to overcome the implications of
    McPherson’s reasoning on this question, which we do not lightly
    cast aside. (Cf. City and County of San Francisco v. All Persons
    Interested in Matter of Proposition C (2020) 
    51 Cal.App.5th 703
    ,
    715–717 [interpreting constitutional provision by applying
    reasoning and principles from Supreme Court decision
    interpreting separate but similar constitutional provision].) We
    see no justification for reaching a different interpretation than
    McPherson reached with respect to virtually identical language.
    Seeking to distinguish McPherson and its point that a
    literal reading of “unlimited” would exclude the veto power,
    plaintiffs argue that article XIV, section 4, unlike the PUC-
    related provision at issue in McPherson, states that the
    Legislature’s power to enact workers’ compensation laws must be
    exercised “by appropriate legislation.” They argue that
    appropriate legislation must be enacted bicamerally and
    presented to the Governor for veto.
    Framing the inquiry in terms of “appropriate legislation”
    does not change the analysis. If we followed plaintiffs’ argument,
    we would still have to determine what makes legislation
    appropriate or inappropriate, which would entail choosing which
    constitutional provisions would apply and which would not. It is
    not clear why the veto power and the initiative power would fall
    on different sides of that line. Plaintiffs characterize the veto as
    part of the “normal legislative process” and article II, section
    10(c)’s voter-approval requirement for amendments to initiative
    20
    statutes as a “special limitation” on the Legislature’s power. But
    plaintiffs cite nothing to support this distinction; both such
    limitations derive from the Constitution and have equal force.
    Plaintiffs’ distinction is also inconsistent with the principle that
    “ ‘the Constitution’s initiative and referendum provisions should
    be liberally construed to maintain maximum power in the
    people.’ ” (McPherson, 
    supra,
     38 Cal.4th at p. 1032.)
    Rather than take up such free-floating standards, we
    adhere instead to Hustedt v. Workers’ Comp. Appeals Bd. (1981)
    
    30 Cal.3d 329
    . The Supreme Court there affirmed that “the
    adoption of article XIV, section 4 ‘effected a repeal pro tanto’ of
    any state constitutional provisions which conflicted with that
    amendment. [Citations.] A pro tanto repeal of conflicting state
    constitutional provisions removes ‘insofar as necessary’ any
    restrictions which would prohibit the realization of the objectives
    of the new article.” (Id. at p. 343; see 
    id.
     at pp. 343–344 [article
    XIV, section 4 did not effect a pro tanto repeal of the judiciary’s
    constitutional authority to discipline attorneys because
    permitting the Workers’ Compensation Appeal Board (WCAB) to
    discipline attorneys was not necessary to effectuate the objectives
    of article XIV, section 4].) Because McPherson teaches that
    article XIV, section 4’s objective was not to give the Legislature
    exclusive authority over workers’ compensation laws, but rather
    to give such authority to the Legislature or the voters, Hustedt
    dictates that article XIV, section 4 did not repeal the voters’
    21
    initiative power to enact legislation concerning workers’
    compensation.10
    It is also important to remember that, by its nature, “ ‘the
    California Legislature possesses plenary legislative authority
    except as specifically limited by the California Constitution.’ ”
    (Howard Jarvis Taxpayers Assn. v. Padilla (2016) 
    62 Cal.4th 486
    ,
    498; see Yosemite L. Co. v. Industrial Acc. Com. (1922) 
    187 Cal. 774
    , 780 [“Nothing is added to the force of [article XIV, section 4]
    by the use of the word ‘plenary.’ If the legislature has power to
    do a certain thing, its power to do it is always plenary. It is
    merely surplus verbiage”].) Thus, unlike grants of power to
    Congress in the United States Constitution, the voters had no
    need to give a specific power to the Legislature to allow that body
    to legislate on workers’ compensation. (City and County of San
    Francisco v. Workers’ Comp. Appeals Bd., supra, 22 Cal.3d at
    p. 114 [“[e]ven without such specific authorization [in article XIV,
    10 The dissenting opinion cites the statement in Hustedt,
    supra, 30 Cal.3d at p. 343, fn. 11, that Mathews interpreted the
    paragraph in article XIV, section 4 ratifying and confirming the
    creation and existence of the WCAB and all its functions “to bar
    only the invalidation of ‘basic features’ of the workers
    compensation laws ‘as they have existed since 1911.’ ” (Conc. &
    dis. opn., post, at p. 6.) While the language is perhaps
    ambiguous, the reference to “invalidation” suggests that Hustedt
    read Mathews, as we do, as holding only that article XIV,
    section 4 was not intended to render invalid any preexisting
    features of the workers’ compensation system. If Hustedt
    intended to announce a sweeping holding that the 1918 workers’
    compensation system was beyond the Legislature’s ability to
    change (which was unnecessary to resolve the dispute before it),
    we believe it would have said so in far more direct language.

    firmly established view of the concept of the police power, to
    adopt appropriate legislative measures for the protection of
    employees and their dependents”].) The only reason to enact
    article XIV, section 4 was to create an exemption from provisions
    elsewhere in the Constitution that might have been viewed at the
    time as preventing the enactment of certain features of such
    legislation. (See Western Indemnity Co. v. Pillsbury (1915)

    prevented the enactment of workers’ compensation legislation, so
    article XIV, section 4 did not repeal any aspect of the initiative
    power.
    To plaintiffs, Proposition 22 is inconsistent with article
    XIV, section 4 because the benefits that Proposition 22 gives app-
    23
    based drivers do not amount to a “complete system of workers’
    compensation” as defined in article XIV, section 4.11 But article
    XIV, section 4 does not require every worker to be covered by
    workers’ compensation. (Facundo-Guerrero v. Workers’ Comp.

    section 4 did not prevent the Legislature from taking away the
    authority of the WCAB to determine medical necessity of
    treatment, which it had held since 1917 (Stats. 1917, ch. 586,
    § 9(a), p. 837), and vesting it instead in an independent medical
    review organization whose determinations are effectively final.
    (Accord, Ramirez v. Workers’ Comp. Appeals Bd. (2017)
    
    10 Cal.App.5th 205
    , 226; see also Rio Linda Union School Dist. v.
    Workers’ Comp. Appeals Bd. (2005) 
    131 Cal.App.4th 517
    , 525–
    527, 532 [workers’ compensation rights are wholly statutory, so
    Legislature could change existing law (which dated to 1917, see
    Stats. 1917, ch. 586, § 3(4), p. 833) and require apportionment of
    disability based on causation and pre-existing conditions].) The
    dissenting opinion recognizes that the WCAB’s authority to
    resolve disputes between employers and employees over medical
    necessity of treatment was a basic feature of the pre-1918 law.
    (Conc. & dis. opn., post, at p. 46.) By contrast, no case has ever

    changing basic features of the pre-1918 workers’ compensation
    system, as the dissenting opinion would hold.
    25
    purposes of workers’ compensation]), so the relative insufficiency
    of Proposition 22’s benefits is of no constitutional moment.
    In their last argument, plaintiffs contend that article XIV,
    section 4’s reference to the Legislature should not be read as
    including the initiative power because doing so changes the scope
    of the article XIV, section 4 power. They reason that the
    Legislature on its own could not restrict its own future power,
    while an initiative like Proposition 22 can. (In re Collie (1952)
    
    38 Cal.2d 396
    , 398.) Initiatives do bind the Legislature by virtue
    of article II, section 10(c), discussed further, post, in a way that
    the Legislature cannot bind itself. (Rossi v. Brown (1995)
    
    9 Cal.4th 688
    , 715–716.) But the same argument could be made
    about any reference to the Legislature in the Constitution, which
    would completely defeat the long-established rule that references
    to the Legislature should be read as including the initiative
    power. (McPherson, 
    supra,
     38 Cal.4th at p. 1043.) We therefore
    reject this argument.
    We turn finally to what the dissenting opinion deems
    article XIV, section 4’s “particularly notable” declaration that the
    workers’ compensation scheme shall be “binding upon all
    departments of the state government.” (Conc. & dis. opn., post, at
    p. 39, quoting Cal. Const., art. XIV, § 4). Based on its
    interpretation of that phrase, the dissent asserts that when the
    people adopt an initiative statute, they “are encompassed within
    the phrase ‘all departments of State Government.’ ” (Conc. & dis.
    opn., post, at p. 39.) From that premise, the dissent then
    concludes that when there is a conflict between a legislative
    26
    enactment and an initiative statute relating to workers’
    compensation, the electorate is bound by the Legislature’s view of
    workers’ compensation policy. (Id. at pp. 40–41, 44.) The
    dissenting opinion cites nothing to support its assertion that the
    people enacting an initiative constitute a “department of the state
    government” or its conclusion that the phrase “binding upon all
    departments of the state government” was intended to convey a
    limitation on the initiative power. In actuality, this phrase
    appears to have been intended only to mean that the workers’
    compensation system applies to the state and local governments
    as employers. (Bautista v. State of California (2011)
    
    201 Cal.App.4th 716
    , 726; Sacramento v. Industrial Acc. Com.
    (1925) 
    74 Cal.App. 386
    , 395.)
    A second, more fundamental problem is that construing
    “departments of the State government” to include the
    electorate—one premise for the dissenting opinion’s conclusion
    that article XIV, section 4 limits the initiative power—runs afoul
    of California Cannabis Coalition v. City of Upland, 
    supra,
    3 Cal.5th 924
    . There, our Supreme Court rejected the City’s
    contention that a constitutional provision limiting the authority
    of “local government” with respect to taxes should be construed to
    mean that such a limitation applies to the electorate when it
    enacts a tax-related initiative statute. (Id. at pp. 930–931
    [construing article XIII C].) Not only did the court reason that
    construing “local government” to include the electorate was
    contrary to the term’s common understanding (California
    Cannabis Coalition, at p. 937), the court also repeatedly
    27
    instructed that there must be some “unambiguous indication that
    a provision’s purpose was to constrain the initiative power” before
    such a limitation would be imposed. (Id. at p. 945; see id. at p.
    946 [“the best way to implement our oft-repeated references to
    the importance of the initiative is to avoid presuming that a
    provision constrains that power without a clear statement or
    equivalent evidence that such was the provision’s intended
    purpose” (italics added)], 948 [“Unless a provision explicitly
    constrains the initiative power or otherwise provides a similarly
    clear indication that its purpose includes constraining the voters’
    initiative power, we will not construe provisions as imposing such
    limitations” (italics added)].)
    Similar to the phrase “local government” in the
    constitutional provision at issue in California Cannabis
    Coalition, article XIV, section 4’s reference to “departments of the
    state government” contains no unambiguous indication that the
    phrase was intended to include the electorate and thereby
    constrain the people’s initiative power. This does not make the
    voters “exogenous” to our plan of government (conc. & dis. opn.,
    post, at p. 39); the California Constitution plainly provides for the
    initiative power, after all. This merely recognizes that a
    reference to “State government” or its departments does not
    naturally include the voters.
    We therefore conclude that Proposition 22 does not violate
    article XIV, section 4.
    28
    III. Single-subject Rule
    In addition to challenging the entirety of Proposition 22
    based on article XIV, section 4, plaintiffs argued below that
    section 7465(c)(4) violates article II, section 8, subdivision (d) of
    the Constitution, which provides that “[a]n initiative measure
    embracing more than one subject may not be submitted to the
    electors or have any effect.” Plaintiffs asserted that section
    7465(c)(4) violates this single-subject rule because it is not
    reasonably germane to the purpose of Proposition 22 and imposes
    restrictions not substantively addressed in the initiative. While
    directed at only section 7465(c)(4), plaintiffs’ challenge still aims
    at the complete invalidation of Proposition 22 because “when an
    initiative measure violates the single-subject rule, severance is
    not an available remedy.” (See Senate of the State of Cal. v. Jones
    (1999) 
    21 Cal.4th 1142
    , 1168.)
    The Supreme Court’s “jurisprudence in this area is well
    developed.” (Briggs, 
    supra,
     3 Cal.5th at p. 828.) It has “ ‘upheld
    a variety of initiative measures in the face of a single-subject
    challenge, emphasizing that the initiative process occupies an
    important and favored status in the California constitutional
    scheme and that the single-subject requirement should not be
    interpreted in an unduly narrow or restrictive fashion that would
    preclude the use of the initiative process to accomplish
    comprehensive, broad-based reform in a particular area of public
    concern.’ ” (Ibid.) “ ‘[T]he single-subject provision does not
    require that each of the provisions of a measure effectively
    interlock in a functional relationship. [Citation.] It is enough
    29
    that the various provisions are reasonably related to a common
    theme or purpose.’ ” (Ibid.) “The ‘reasonably germane’ standard
    is applied ‘in an accommodating and lenient manner so as not to
    unduly restrict . . . the people’s right to package provisions in a
    single bill or initiative.’ ” (Id. at p. 829.)
    Section 7465 is the only statutory section in the article
    titled “Amendment.” Subdivision (a) of section 7465 allows the
    Legislature to amend Proposition 22 under certain conditions,
    including that any amendments must be enacted by a seven-
    eighths majority and must further the purpose of the initiative.
    (§ 7465, subd. (a).) Under the Constitution, the Legislature may
    also amend an initiative statute if the voters subsequently
    approve it. (Cal. Const., art. II, § 10, subd. (c).)
    Section 7465(c)(4) defines a specific type of legislation that
    would constitute an amendment of Proposition 22, stating, “Any
    statute that authorizes any entity or organization to represent
    the interests of app-based drivers in connection with drivers’
    contractual relationships with network companies, or drivers’
    compensation, benefits, or working conditions, constitutes an
    amendment” to the initiative. Section 7465(c)(4)’s language is
    broad, but it is undisputed that if the Legislature seeks to enact a
    law allowing app-based drivers to collectively bargain, it must
    comply with the requirements for amendments to the initiative.
    Such a legislative enactment would be necessary for drivers to
    collectively bargain because antitrust law prevents independent
    contractors from doing so unless they obtain specific state
    authorization. (Chamber of Commerce of the USA v. City of
    30
    Seattle (9th Cir. 2018) 
    890 F.3d 769
    , 780–790 (Chamber of
    Commerce); 
    15 U.S.C. § 17
    .)
    Plaintiffs alleged and the trial court agreed that section
    7465(c)(4) does not relate to the purposes of Proposition 22, as
    specifically set forth in section 7450: protecting app-based
    drivers’ rights to work as independent contractors, protecting
    their right to have flexibility in their schedules and locations,
    offering them new benefits and protections, and improving public
    safety relating to app-based drivers. (§ 7450, subds. (a)–(d).) We
    conclude to the contrary that section 7465(c)(4) is “ ‘reasonably
    related to a common theme or purpose’ ” of the initiative and thus
    satisfies the single-subject rule, given the accommodating and
    lenient fashion in which the Supreme Court has instructed us to
    apply it. (Briggs, 
    supra,
     3 Cal.5th at p. 828.)
    Proposition 22’s common theme or purpose is, as
    interveners argue, the creation of a new balance of benefits and
    obligations for app-based drivers in lieu of either traditional
    employment or traditional independent contractor status.
    Section 7465(c)(4) is reasonably germane to this subject because
    it relates to drivers’ ability to change that balance by limiting the
    Legislature’s ability to authorize collective bargaining over
    drivers’ compensation, benefits, or working conditions. Stated
    slightly more generally, Proposition 22’s overarching single
    subject is regulation of the relationships between app-based
    drivers and network companies, and section 7465(c)(4)’s
    restrictions on the Legislature’s ability to allow drivers to
    collectively bargain relate to those relationships.
    31
    The trial court took a different approach to the analysis,
    which plaintiffs support on appeal. Rather than identifying a
    single purpose for the entire law, plaintiffs recite Proposition 22’s
    four declared purposes: classifying drivers as independent
    contractors, protecting driver independence, providing new
    benefits, and protecting public safety. (§ 7450, subds. (a)–(d).)
    Like the trial court, they point out that section 7465(c)(4)’s
    restrictions on the enactment of laws allowing collective
    bargaining have no relationship to the rest of the initiative’s
    sections and are not necessary to achieve its four stated purposes.
    Plaintiffs resist interveners’ definition of Proposition 22’s purpose
    as comprehensive reform of app-based drivers’ relationships with
    network companies, arguing that we should rely only on the
    express statements of Proposition 22’s purpose in its title,
    findings, and declarations.
    Given their argument here, plaintiffs are correct that we
    should draw Proposition 22’s theme or purpose from its stated
    aims, but plaintiffs’ framing of their single-subject challenge
    requires us to summarize and derive from Proposition 22’s
    multiple purposes a single, overarching theme or purpose against
    which to measure section 7465(c)(4). This is how the Supreme
    Court has conducted the single-subject analysis, including in the
    cases that plaintiffs cite in support of their argument. (Briggs,
    supra, 3 Cal.5th at p. 831 [identifying initiative’s purpose as “an
    extensive reform of the entire system of capital punishment to
    make it more efficient, less expensive, and more responsive to the
    rights of victims”]; Manduley v. Superior Court (2002) 
    27 Cal.4th 32
    537, 576 [“Addressing the problem of juvenile crime and gang-
    related crime properly can be considered the common purpose of
    Proposition 21”]; Legislature v. Eu (1991) 
    54 Cal.3d 492
    , 512
    [“The unifying theme or common purpose of Proposition 140 is
    incumbency reform”].) League of Women Voters v. Eu (1992)
    
    7 Cal.App.4th 649
    , 654–655, which plaintiffs also claim supports
    their position, compared the process of identifying a measure’s
    purpose to the arithmetic involved in adding unlike fractions, in
    that courts should “identify the lowest common denominator of
    the various provisions of the initiative, i.e., the most narrowly
    defined object or purpose which nevertheless is sufficiently broad
    to encompass all such provisions.” (Id. at p. 659.) Such an
    approach starts with the provisions of an initiative and draws
    from them the overall theme or purpose of the entire measure.
    Plaintiffs’ piecemeal comparison of section 7465(c)(4) to
    each of the initiative’s separate purposes misses the forest for the
    trees. Two of Proposition 22’s stated purposes, classification of
    drivers as independent contractors and protecting driver
    independence, relate to each other, but the other two, driver
    benefits and public safety, do not. (§ 7450, subds. (a)–(d).) We
    therefore cannot give each of these purposes equal significance,
    as plaintiffs urge us to do, because doing so would mean
    Proposition 22 has three purposes and therefore three subjects.
    Additionally, plaintiffs’ approach would make the single-subject
    inquiry unworkable. Initiatives commonly state multiple
    purposes or motivating concerns, between their titles, preambles,
    findings, declarations, and substantive provisions. Proposition 22
    33
    is relatively simple in this regard with four purposes. Other
    initiatives state many more, like the proposition at issue in
    Briggs, which set out 11 findings and declarations. (Briggs,
    supra, 3 Cal.5th at p. 823; Voter Information Guide, Gen. Elec.
    (Nov. 8, 2016) text of Prop. 66, § 2, pp. 212–213.) Eschewing the
    identification of initiatives’ common or dominant purpose and
    conducting a multivariate analysis, as plaintiffs advocate, is not
    feasible. To assess their claim that section 7465(c)(4) represents
    a different subject than the remainder of the initiative, we must
    elucidate from the initiative’s stated purposes a single theme or
    subject against which we can evaluate section 7465(c)(4).
    In a fallback argument, plaintiffs contend that even if
    Proposition 22’s theme or subject can be isolated from its stated
    purposes, its theme is the classification of app-based drivers for
    purposes of employment law and section 7465(c)(4) does not
    relate to classification. This description of Proposition 22’s
    subject is too narrow. Classification is just one of the initiative’s
    stated purposes, and only two of the initiative’s statutory sections
    relate to it. (§§ 7451 [reclassifying drivers], 7452.5 [nothing else
    in Proposition 22 should be construed as altering the
    classification of app-based drivers as independent contractors].)
    Most of the rest of the initiative’s statutory sections are devoted
    to achieving its other stated purposes by detailing the benefits
    that app-based drivers must receive and public safety
    requirements with which they must comply. (§§ 7454–7462.)
    These sections do not relate to classification. Because these
    provisions represent the bulk of the initiative, plaintiffs’
    34
    statement of the initiative’s overall subject cannot be correct.
    Moreover, even if classification could be said to be Proposition
    22’s single subject, that determination would not help plaintiffs.
    If the initiative’s benefits and public safety requirements sections
    relate to classification (perhaps because they provide benefits and
    obligations to replace those that app-based drivers would have as
    employees), then section 7465(c)(4), too, relates to classification
    because it concerns the Legislature’s authority to change the
    procedures by which drivers can increase the replacement
    benefits.
    Plaintiffs’ remaining arguments are unavailing. First, they
    argue that section 7465(c)(4) restricts the Legislature’s power to
    allow drivers to collectively bargain even though the rest of the
    initiative, which plaintiffs describe as its “operative” provisions,
    does not mention representation of drivers, either individually or
    collectively. We have more to say about the relationship between
    section 7465(c)(4) and the rest of Proposition 22, post, but for
    purposes of the single-subject rule, plaintiffs’ distinction between
    section 7465(c)(4) and the initiative’s operative provisions is
    irrelevant. Plaintiffs cite no authority that requires different
    provisions of an initiative to cross-reference each other, and the
    law is to the contrary. “[A] measure’s separate provisions have
    been considered to be reasonably germane to each other within
    the meaning of the standard so long as all of the provisions are
    reasonably germane to a single common theme, purpose, or
    subject.” (Californians for an Open Primary v. McPherson (2006)
    
    38 Cal.4th 735
    , 764, fn. 29, italics omitted.)
    35
    Second, plaintiffs contend that collective bargaining is a
    separate subject because collective bargaining would not impair
    drivers’ ability to set their own hours or work independently, and
    collective bargaining for increased benefits would not conflict
    with the benefits Proposition 22 provides, which are established
    as minimum benefits. (See, e.g., §§ 7454, subd. (a)(1)–(2)
    [requiring health care subsidy “greater than or equal to” certain
    reference standards], 7455, subd. (a) [setting “minimum”
    coverage for insurance].) But the single-subject test does not look
    at whether a provision is necessary for the rest of an initiative to
    function. Plaintiffs are in effect seeking to impose a requirement
    that an initiative’s provisions must all functionally relate to one
    another. The Supreme Court has already rejected this argument.
    (Briggs, supra, 3 Cal.5th at p. 828 [“ ‘[T]he single-subject
    provision does not require that each of the provisions of a
    measure effectively interlock in a functional relationship’ ”].)
    Third, plaintiffs compare this case to California Trial
    Lawyers Assn. v. Eu (1988) 
    200 Cal.App.3d 351
    , 358 (Trial
    Lawyers), which held that an initiative violated the single-subject
    rule. The comparison is not apt. Trial Lawyers involved a
    challenge to an initiative titled “Insurance Cost Control Initiative
    of 1988,” which consisted of 120 pages covering 67 sections.
    (Trial Lawyers, at pp. 354–355.) The initiative would have
    created “revolutionary” changes in insurance law, including
    creation of no-fault insurance for auto accidents, limiting
    recovery for injuries beyond the no-fault limits, reducing
    premiums for certain coverages, and limiting future insurance
    36
    regulation legislation. (Id. at pp. 355–356.) One section of the
    initiative, located “inconspicuously” at pages 52 and 53 of the
    measure, would have enacted a statute providing that public
    officials would not be required to disqualify themselves from any
    decisions affecting an insurer’s interests based upon the insurer’s
    campaign contributions. (Id. at p. 356.) The court found no
    possible connection between avoiding such disqualification and
    the general object and purpose of the initiative. (Id. at p. 359.)
    The court rejected the initiative supporter’s argument that the
    provision was germane because both it and the rest of the
    initiative dealt generally with regulation of insurance industry
    practices. (Id. at pp. 359–360.) The court first noted that the
    express purpose of the initiative was to control insurance costs.
    (Id. at p. 360.) The court further concluded that the supporter’s
    argument would mean that any two provisions that affected the
    business of insurance would comply with the single-subject rule,
    which the court found would “render the constitutional single-
    subject limitation nugatory.” (Ibid.)
    Proposition 22 is not like the measure at issue in Trial
    Lawyers. The only discernable relationship between the anti-
    disqualification provision of that initiative and the rest of the
    measure was that both had some effect on the business of
    insurance. (Trial Lawyers, supra, 200 Cal.App.3d at p. 360.) But
    as just discussed, section 7465(c)(4) relates to the rest of
    Proposition 22 because both concern the subject of app-based
    drivers’ benefits, with the bulk of Proposition 22 establishing that
    drivers would not receive employee benefits and providing a
    37
    replacement set of benefits, and section 7465(c)(4) restricting the
    Legislature’s ability to allow drivers to negotiate collectively to
    increase those benefits. Because of the “undeniably liberal
    nature of the standards which have been formulated” in the
    Supreme Court’s cases, this connection is sufficient. (Trial
    Lawyers, at p. 359.)
    Finally, plaintiffs seek to buttress their arguments by
    pointing out that the single-subject rule is intended to avoid voter
    confusion and the exploitation of the initiative process through
    the combination of disparate provisions which might not have
    commanded majority support if considered separately, which is
    known as logrolling. (Amador Valley Joint Union High Sch. Dist.
    v. State Bd. of Equalization (1978) 
    22 Cal.3d 208
    , 231–232.)
    However, as plaintiffs admit, voter confusion and logrolling are
    not standalone bases for invalidating an initiative. “The single-
    subject rule is the method by which the state Constitution guards
    against” those risks, so we may examine only whether
    Proposition 22 satisfies the rule, without also examining whether
    it satisfies the purposes behind the rule. (Kennedy Wholesale,
    Inc. v. State Bd. of Equalization (1991) 
    53 Cal.3d 245
    , 255;
    accord, California Gillnetters Assn. v. Department of Fish &
    Game (1995) 
    39 Cal.App.4th 1145
    , 1162 & fn. 11.) While
    concerns about voters’ understanding of section 7465(c)(4) may
    bear on our interpretation of the statute for the purposes of
    plaintiffs’ separation of powers challenge, as we discuss post,
    these concerns are not sufficient to rescue plaintiffs’ otherwise
    unpersuasive single-subject rule argument.
    38
    IV.   Separation of Powers
    We turn now to plaintiffs’ separation of powers challenge
    with respect to sections 7465(c)(3) and (4). We have already
    discussed section 7465(c)(4) in detail in relation to the single-
    subject rule. Section 7465(c)(3) defines another class of
    legislation that constitutes an amendment to Proposition 22,
    namely, “[a]ny statute that prohibits app-based drivers from
    performing a particular rideshare service or delivery service
    while allowing other individuals or entities to perform the same
    rideshare service or delivery service, or otherwise imposes
    unequal regulatory burdens upon app-based drivers based on
    their classification status.” Plaintiffs argued in their petition
    that sections 7465(c)(3) and (4) are facially unconstitutional
    because they intrude on the judiciary’s power to define what
    constitutes an amendment to Proposition 22, and that section
    7465(c)(4) on its face unconstitutionally limits the Legislature’s
    authority to enact related but distinct legislation. The trial court
    found that section 7465(c)(3) passes constitutional muster but
    concluded that section 7465(c)(4) is invalid because it violates the
    separation of powers by intruding on the Legislature’s powers.
    As noted ante, section 7465 represents an exercise of the
    voters’ power under article II, section 10(c) “to decide whether or
    not the Legislature can amend or repeal initiative statutes. This
    power is absolute and includes the power to enable legislative
    amendment subject to conditions attached by the voters.”
    (California Common Cause v. Fair Political Practices Com. (1990)
    
    221 Cal.App.3d 647
    , 652, italics omitted.) For lack of a better
    39
    term, we will refer to the area of law in which an initiative
    constrains the Legislature’s legislative actions as the initiative’s
    article II, section 10(c) shadow.
    A. Facial challenge
    Interveners and the state first contend the trial court erred
    in holding section 7465(c)(4) invalid because plaintiffs fail to meet
    the standard for facial challenges, as they cannot show that
    section 7465(c)(4) is unconstitutional in all or almost all of its
    applications. We disagree.
    “The standard for a facial constitutional challenge to a
    statute is exacting. It is also the subject of some uncertainty.”
    (Today’s Fresh Start, Inc. v. Los Angeles County Office of
    Education (2013) 
    57 Cal.4th 197
    , 218.) In the stricter
    formulation of the standard, “legislation is invalid only if it
    presents a total and fatal conflict with applicable constitutional
    prohibitions.” (T-Mobile West LLC v. City and County of San
    Francisco (2019) 
    6 Cal.5th 1107
    , 1117, fn. 6.) This standard
    requires a challenger to “ ‘ “ ‘establish that no set of
    circumstances exists under which the [law] would be valid.’ ” ’ ”
    (American Civil Rights Foundation v. Berkeley Unified School
    Dist. (2009) 
    172 Cal.App.4th 207
    , 216.) But other cases have
    “ ‘applied a more lenient standard, asking whether the statute is
    unconstitutional “in the generality or great majority of cases.” ’ ”
    (California School Boards Assn. v. State of California (2019)
    
    8 Cal.5th 713
    , 724.) “Either way, we consider only the text and
    purpose of the statute, and ‘[plaintiffs] cannot prevail by
    suggesting that in some future hypothetical situation
    40
    constitutional problems may possibly arise as to the particular
    application of the statute.’ ” (Ibid., italics omitted.)
    Interveners press for the application of the stricter
    standard and argue it is not met because they can imagine
    collective bargaining laws that would constitute amendments to
    Proposition 22, demonstrating that section 7465(c)(4) has at least
    some constitutional applications. For example, interveners argue
    that section 7465(c)(4) would be constitutional as applied to a
    statute authorizing mandatory collective bargaining over
    minimum hours that app-based drivers must work (see Chamber
    of Commerce, supra, 890 F.3d at pp. 777–778), since such a
    statute would amend Proposition 22 by taking away “the
    individual right of every app-based rideshare and delivery driver
    to have the flexibility to set their own hours for when, where, and
    how they work.”13 (§ 7450, subd. (b).)
    As they did below, plaintiffs argue that by attempting to
    define what constitutes an amendment, sections 7465(c)(3) and
    (4) intrude on the judiciary’s power to define Proposition 22’s
    article II, section 10(c) shadow. Interveners’ contention that
    plaintiffs’ separation of powers challenge is not facial ignores this
    13 Plaintiffs also argue that section 7465(c)(4) would
    prohibit the Legislature from allowing the Labor Commissioner
    or some other public entity to represent individual app-based
    drivers as to their contractual relationships with transportation
    and delivery network companies. Interveners do not offer
    examples of laws authorizing public representation of individual
    drivers that section 7465(c)(4) could constitutionally define as
    amendments to Proposition 22. Since the parties focus primarily
    on section 7465(c)(4) as a measure directed at collective
    bargaining, we do the same.
    41
    aspect of plaintiffs’ argument, which does not depend on the
    content of any specific piece of legislation; rather, the mere
    existence of sections 7465(c)(3) and (4) completes the alleged
    intrusion. In other words, even if sections 7465(c)(3) and (4)
    would correctly declare some statutes to be amendments to
    Proposition 22, sections 7465(c)(3) and (4) would still violate the
    judiciary’s exclusive right to make such determinations.
    Plaintiffs’ separation of powers challenge based on this intrusion
    on the judiciary’s power is therefore a facial one, even under
    interveners’ argument.
    As for plaintiffs’ argument that section 7465(c)(4) intrudes
    on the Legislature’s power, plaintiffs concede that interveners’
    hypothetical statute authorizing mandatory collective bargaining
    over minimum hours that app-based drivers must work would
    constitute an amendment to Proposition 22.14 But they argue it
    would be an amendment even in the absence of section 7465(c)(4),
    so section 7465(c)(4) would be irrelevant in such a scenario. They
    urge us to disregard such situations and focus only on scenarios
    in which section 7465(c)(4) would be relevant. Thus, plaintiffs’
    facial attack on section 7465(c)(4) is more accurately described as
    an attack on section 7465(c)(4) in all instances in which it would
    declare a collective bargaining statute to be an amendment of
    14 In the trial court, plaintiffs contended that section
    7465(c)(3) also intrudes on the Legislature’s power, not just
    section 7465(c)(4). The trial court rejected this argument, and
    plaintiffs do not renew it on appeal. We express no opinion on
    this point or on whether such an argument would be cognizable
    as a facial challenge in the same manner as plaintiffs’ contention
    that section 7465(c)(4) intrudes on the Legislature’s power.
    42
    Proposition 22 that would not otherwise constitute an
    amendment. Or, using the terminology we have adopted here, it
    is an attack on section 7465(c)(4) in every instance in which it
    affects Proposition 22’s article II, section 10(c) shadow.
    The Supreme Court endorsed plaintiffs’ approach in a
    slightly different context in American Academy of Pediatrics v.
    Lungren (1997) 
    16 Cal.4th 307
     (plur. opn. of George, C. J.).
    There, the Supreme Court noted, “ ‘[l]egislation is measured for
    consistency with the Constitution by its impact on those whose
    conduct it affects. . . . The proper focus of constitutional inquiry is
    the group for whom the law is a restriction, not the group for
    whom the law is irrelevant.’ ” (Id. at p. 345.)
    American Academy of Pediatrics v. Lungren paired this
    rationale with its discussion of the more lenient standard for
    facial challenges, which some Courts of Appeal view as applicable
    only in fundamental rights cases, but the Supreme Court
    continues to treat the standard of review for facial challenges as
    generally unsettled. (E.g., T-Mobile West LLC v. City and County
    of San Francisco (2016) 
    3 Cal.App.5th 334
    , 345, fn. 12 [rejecting
    application of lenient standard as appropriate only for First
    Amendment and abortion rights], affd. (2019) 
    6 Cal.5th 1107
    ;
    T-Mobile West LLC v. City and County of San Francisco, supra, 6
    Cal.5th at p. 1117, fn. 6 [declining to settle on a “precise
    formulation of the applicable standard”].) Because plaintiffs’
    argument fits squarely within the rationale expressed in
    American Academy of Pediatrics v. Lungren for measuring the
    constitutionality of statutes by looking only at the behavior they
    43
    restrict, and nothing about that rationale is logically or
    inherently related to fundamental rights or the more lenient
    facial standard, American Academy of Pediatrics v. Lungren
    supports our conclusion that plaintiffs’ challenge to section
    7465(c)(4) may proceed as a facial attack.15 (Cf. San Francisco
    Apartment Assn. v. City and County of San Francisco (2016)
    
    3 Cal.App.5th 463
    , 486–488 [finding that plaintiffs had mounted
    a successful facial challenge to a local ordinance on preemption
    grounds by focusing on the instances where the local ordinance
    would in fact impermissibly impact plaintiffs’ exercise of state
    law rights, not the ordinance in isolation].)
    Our acceptance of plaintiffs’ challenge as a facial one does
    not, as interveners argue, make a facial challenge the easiest
    challenge to assert rather than the hardest by ignoring the
    constitutional applications of the statute and focusing only on the
    unconstitutional ones. We are not ignoring the constitutional
    applications of the statute, but rather ignoring the applications
    where the statute would be irrelevant or, perhaps more
    accurately, immaterial. If every instance in which section
    7465(c)(4) has a material impact is also one in which it is
    unconstitutional, then the law is facially infirm, even if it could
    be constitutionally applied as surplusage in other instances.
    15 Although it is plaintiffs’ burden to establish facial
    invalidity of section 7465(c)(4), we note that interveners and the
    state have not rebutted plaintiffs’ challenge by pointing to any
    instance in which section 7465(c)(4) could constitutionally apply
    to legislation that would fall outside the “natural” article II,
    section 10(c) shadow.
    44
    B. Ripeness
    Interveners and the state next contend plaintiffs’
    separation of powers challenge is not ripe because the Legislature
    has not enacted any legislation that might constitute an
    amendment to Proposition 22. “The ripeness requirement, a
    branch of the doctrine of justiciability, prevents courts from
    issuing purely advisory opinions. [Citation.] It is rooted in the
    fundamental concept that the proper role of the judiciary does not
    extend to the resolution of abstract differences of legal opinion. It
    is in part designed to regulate the workload of courts by
    preventing judicial consideration of lawsuits that seek only to
    obtain general guidance, rather than to resolve specific legal
    disputes. However, the ripeness doctrine is primarily bottomed
    on the recognition that judicial decisionmaking is best conducted
    in the context of an actual set of facts so that the issues will be
    framed with sufficient definiteness to enable the court to make a
    decree finally disposing of the controversy. On the other hand,
    the requirement should not prevent courts from resolving
    concrete disputes if the consequence of a deferred decision will be
    lingering uncertainty in the law, especially when there is
    widespread public interest in the answer to a particular legal
    question.” (Pacific Legal Foundation v. California Coastal Com.
    (1982) 
    33 Cal.3d 158
    , 170.)
    The Supreme Court has applied a two-prong test for
    deciding whether a dispute is ripe, examining “ ‘the fitness of the
    issues for judicial decision and the hardship to the parties of
    withholding court consideration.’ ” (Pacific Legal Foundation v.
    45
    California Coastal Com., supra, 33 Cal.3d at pp. 171–174, italics
    omitted.) “ ‘Under the first prong, the courts will decline to
    adjudicate a dispute if “the abstract posture of [the] proceeding
    makes it difficult to evaluate . . . the issues” [citation], if the court
    is asked to speculate on the resolution of hypothetical situations
    [citation], or if the case presents a “contrived inquiry” [citation].
    Under the second prong, the courts will not intervene merely to
    settle a difference of opinion; there must be an imminent and
    significant hardship inherent in further delay.’ ” (Communities
    for a Better Environment v. State Energy Resources Conservation
    & Development Com. (2017) 
    19 Cal.App.5th 725
    , 733–734.)
    The fitness prong of this test indicates plaintiffs’ separation
    of powers challenge to the initiative is ripe because the voters
    have already approved Proposition 22 and, as discussed ante,
    plaintiffs’ challenge to it is a facial one for which concrete facts
    are unnecessary. (Alliance for Responsible Planning v. Taylor
    (2021) 
    63 Cal.App.5th 1072
    , 1082 [“Nothing precludes resolution
    of the controversy, as the facial allegation does not depend on the
    application of the measure to a particular petitioner or future
    County interpretation”].) Interveners emphasize that the
    Legislature has not enacted a statute that plausibly amends
    Proposition 22, so there is no statutory text to interpret to
    determine whether it changes the scope and effect of the
    initiative. But plaintiffs contend the definitions of amendments
    in sections 7465(c)(3) and (4) violate the separation of powers on
    their face, so there is no need to wait for the Legislature to enact
    a specific statute to evaluate plaintiffs’ arguments.
    46
    The hardship prong also militates in favor of finding
    ripeness. Sections 7465(c)(3) and (4) are in effect, so they are
    already intruding on the judiciary’s powers. Section 7465(c)(4)
    can also affect the Legislature’s and stakeholders’ political
    calculations, including those of labor organizations like plaintiff
    SEIU, about whether to try to pass a law allowing app-based
    drivers to collectively bargain or authorizing some other form of
    representation of individual drivers. The only three avenues for
    such legislation to become effective would be if the Legislature
    submits the legislation to the voters for approval, which is a
    costly undertaking; if the Legislature approves the legislation by
    a seven-eighths majority, which is a bar so high as to be virtually
    insurmountable; or if the Legislature passes such legislation by
    less than a seven-eighths majority and the courts subsequently
    agree that section 7465(c)(4) is unconstitutional, which is both
    time-consuming and difficult to predict. Given these problematic
    paths to effective legislation, the most likely outcome is that
    legislators would not even undertake the effort. This is a
    significant hardship justifying judicial resolution at this stage.
    Interveners and the state argue that this type of chilling
    effect is insignificant because the Legislature regularly enacts
    laws even though the courts might find them to be amendments
    to initiatives. (See, e.g., Amwest Surety Ins. Co. v. Wilson (1995)
    
    11 Cal.4th 1243
    , 1261 [rejecting Legislature’s stated claim that a
    statute merely clarified the scope of an initiative].) However,
    interveners do not cite any law requiring a seven-eighths
    majority for passage, which imposes an apparently uniquely high
    47
    barrier to legislative action. Besides, even if the chilling effect
    were not a significant hardship, the concrete nature of the
    parties’ arguments here would still make the issue ripe for our
    resolution. The Supreme Court has held that “the ripeness
    requirement does not prevent [the courts] from resolving a
    concrete dispute if the consequence of a deferred decision will be
    lingering uncertainty in the law, especially when there is
    widespread public interest in the answer to a particular legal
    question.” (Hunt v. Superior Court (1999) 
    21 Cal.4th 984
    , 998.)
    Because the parties’ dispute has enough specificity for judicial
    resolution at present, the uncertainty in the law that sections
    7465(c)(3) and (4) create, as well as the public interest in the
    validity of Proposition 22, counsel in favor of proceeding to the
    merits of plaintiffs’ arguments.
    C. Merits
    Having disposed of interveners’ and the state’s prefatory
    arguments, we turn now to the merits of plaintiffs’ separation of
    powers challenge to sections 7465(c)(3) and (4).
    1. Intrusion on judicial powers
    Plaintiffs first argue that sections 7465(c)(3) and (c)(4)’s
    definitions of amendments intrude on the judiciary’s power
    because only the judiciary has the authority to say what
    constitutes an amendment within the meaning of article II,
    section 10(c).
    “The powers of state government are legislative, executive,
    and judicial. Persons charged with the exercise of one power may
    not exercise either of the others except as permitted by this
    48
    Constitution.” (Cal. Const., art. III, § 3.) “ ‘The judicial power is
    conferred upon the courts by the Constitution and, in the absence
    of a constitutional provision, cannot be exercised by any other
    body.’ ” (McClung v. Employment Development Dept. (2004)
    
    34 Cal.4th 467
    , 472.) “[I]t is well established that it is a judicial
    function to interpret the law, including the Constitution.”
    (Schabarum v. California Legislature (1998) 
    60 Cal.App.4th 1205
    , 1213; accord, Raven v. Deukmejian (1990) 
    52 Cal.3d 336
    ,
    354 [“ ‘The judiciary, from the very nature of its powers and
    means given it by the Constitution, must possess the right to
    construe the Constitution in the last resort’ ”].)
    Because the definitions in sections 7465(c)(3) and (4)
    constitute an attempt to define the boundaries of Proposition 22’s
    article II, section 10(c) shadow, sections 7465(c)(3) and (4) on
    their face intrude on the judiciary’s authority to define the
    meaning of “amendment” in that section of the Constitution. The
    trial court determined otherwise because it read sections
    7465(c)(3) and (4) as defining “amendment” only for purposes of
    the optional, seven-eighths majority procedure in section 7465,
    subdivision (a), not for article II, section 10(c). The trial court is
    correct that sections 7465(c)(3) and (4) only govern which
    amendments must comply with the conditions established in
    section 7465, subdivision (a). But section 7465, subdivision (a)’s
    power to set conditions on the Legislature’s enactment of future
    legislation is the authority conferred by article II, section 10(c).
    If a statute does not qualify as an amendment of Proposition 22
    within the meaning of the Constitution, the Legislature need
    49
    neither secure the voters’ approval nor comply with the
    conditions in section 7465, subdivision (a). Sections 7465(c)(3)
    and (4)’s definitions of “amendment” as used in section 7465,
    subdivision (a) are thus necessarily also an attempt to define
    “amendment” as used in article II, section 10(c), which is
    impermissible because such authority rests solely with the
    judiciary.
    2. Intrusion on legislative powers
    Plaintiffs’ argument that section 7465(c)(4) intrudes on the
    Legislature’s authority, with which the trial court agreed, is
    slightly more intricate but also has merit. In determining
    whether the Legislature has intruded on the voters’ initiative
    power, courts have devised several different definitions of what
    constitutes an amendment of an initiative under article II,
    section 10(c). Decisions have defined an amendment variously as
    “ ‘a legislative act designed to change an existing initiative
    statute by adding or taking from it some particular provision’ ”
    (People v. Superior Court (Pearson) (2010) 
    48 Cal.4th 564
    , 571),
    one that “prohibits what [an] initiative authorizes, or authorizes
    what the initiative prohibits” (ibid.), or one that “changes its
    scope and effect” (Proposition 103 Enforcement Project v.
    Quackenbush (1998) 
    64 Cal.App.4th 1473
    , 1486). But the
    Supreme Court has cautioned against using too broad of a
    formulation because, “despite the strict bar on the Legislature’s
    authority to amend initiative statutes, judicial decisions have
    observed that this body is not thereby precluded from enacting
    laws addressing the general subject matter of an initiative. The
    50
    Legislature remains free to address a ‘ “related but distinct
    area” ’ [citations] or a matter that an initiative measure ‘does not
    specifically authorize or prohibit.’ ” (People v. Kelly (2010) 
    47 Cal.4th 1008
    , 1025–1026 & fn. 19, italics omitted (Kelly).) This
    admonition implicitly recognizes that the definition of an
    amendment for the purposes of article II, section 10(c) operates
    both to prevent the Legislature from “ ‘ “undoing what the people
    have done, without the electorate’s consent” ’ ” (Kelly, at p. 1025)
    and to demarcate the boundaries of the restrictions that an
    initiative places on the Legislature’s broad authority to legislate.
    Collective bargaining legislation would not necessarily
    amend Proposition 22 under any of these definitions. Apart from
    section 7465(c)(4), no other provision of Proposition 22 directly
    concerns the procedures for driver representation or collective
    bargaining. The mere classification of drivers as independent
    contractors is not determinative of their ability to collectively
    bargain, as independent contractors can, in some circumstances,
    collectively bargain. (See Chamber of Commerce, supra, 890 F.3d
    at pp. 780–790; Welf. & Inst. Code, §§ 10420.5, 10423
    [authorizing family child care providers to appoint organizations
    to represent them without making such providers employees].)
    Likewise, the benefits and obligations that Proposition 22
    provides and imposes are established as minimums, not
    maximums, so nothing prevents drivers from negotiating for
    more, collectively or individually. (See, e.g., §§ 7454, subd. (a)(1)–
    (2) [requiring health care subsidy “greater than or equal to”
    certain amounts], 7455, subd. (a) [setting “minimum” coverages
    51
    for insurance], 7458, subd. (e) [nothing in statute “shall be
    interpreted to prevent a network company from imposing
    additional standards relating to criminal history”].) By extending
    Proposition 22’s article II, section 10(c) shadow to bar legislation
    on subjects which Proposition 22 does not otherwise directly
    address, section 7465(c)(4) intrudes on the Legislature’s authority
    to address a “ ‘ “related but distinct area” ’ ” or a matter that
    Proposition 22 “ ‘does not specifically authorize or prohibit.’ ”
    (Kelly, supra, 47 Cal.4th at pp. 1025–1026, italics omitted; cf.
    People v. Nash (2020) 
    52 Cal.App.5th 1041
    , 1059–1060
    [legislation changing the bases for murder liability did not amend
    initiative that mandated increased sentences for murder
    convictions].) On its face, section 7465(c)(4) therefore violates the
    separation of powers for this reason as well.
    3. Interveners’ and the state’s arguments
    Interveners do not defend sections 7465(c)(3) and (4) as
    written and instead downplay them by construing them as
    merely statements of intent, precatory declarations of the voters’
    views of what constitutes an amendment.16 Interveners
    analogize sections 7465(c)(3) and (4) to provisions the Legislature
    commonly deploys when amending initiative statutes. They cite,
    for example, Amwest Surety Ins. Co. v. Wilson, 
    supra,
     
    11 Cal.4th 16
     Although plaintiffs renewed their separation of powers
    challenge to section 7465(c)(3) in their respondents’ brief,
    interveners do not mention section 7465(c)(3) in their reply and
    discuss only section 7465(c)(4). But interveners defended section
    7465(c)(3) and (4) in the trial court on the same basis on which
    they defend section 7465(c)(4) on appeal, so we mention both
    section 7465(c)(3) and (4) in our discussion of their argument.
    52
    at page 1260, which dealt with a statute declaring “that the act
    ‘furthers the purpose of Proposition 103 by clarifying the
    applicability of the proposition to surety insurance.’ ” (See
    Proposition 103 Enforcement Project v. Quackenbush, supra,
    64 Cal.App.4th at p. 1481 [considering a statute stating, “ ‘The
    Legislature finds and declares that this statute furthers the
    purpose of Proposition 103,’ ” italics omitted].)
    Interveners’ construction of sections 7465(c)(3) and (4) is
    not plausible. Questions of purpose are suitable for precatory
    declarations, since they turn on questions of legislative intent
    and will vary from one initiative to another. The Legislature’s or
    the voters’ input could be relevant when discerning such intent.
    Thus, there is no apparent issue with section 7465(c)(1)’s
    definition of Proposition 22’s purposes and section 7465(c)(2)’s
    declaration that a statute that amends section 7451—which
    defines app-based drivers as independent contractors—does not
    further those purposes.
    Unlike sections 7465(c)(1) and (2) or the legislative
    statements that interveners cite, however, sections 7465(c)(3) and
    (4) do not concern Proposition 22’s purposes or what would
    further those purposes. Sections 7465(c)(3) and (4) address the
    distinct question of what constitutes an amendment of
    Proposition 22. (See O.G. v. Superior Court (2021) 
    11 Cal.5th 82
    ,
    99–100 [issues of whether a statute amends an initiative and
    whether amendments further initiative’s purpose are separate].)
    That question is governed by standards announced in numerous
    judicial decisions over the years. By purporting to declare what
    53
    types of enactments would constitute amendments subject either
    to the constitutional alternative of voter approval or section 7465,
    subdivision (a)’s strict seven-eighths majority requirement (and
    associated procedural conditions), sections 7465(c)(3) and (4) seek
    to bypass this jurisprudence or declare what satisfies it, to the
    exclusion of the courts. To the extent that section 7465(c)(4)
    seeks to cast a broader article II, section 10(c) shadow than the
    otherwise applicable judicial definitions of legislative
    amendments, it also intrudes on the Legislature’s authority.
    Interveners also contend that plaintiffs’ argument that
    section 7465(c)(4) intrudes on the Legislature’s authority is a
    single-subject argument in disguise and an attempt to sidestep
    the lenient single-subject standard in favor of a “stricter (but
    undefined and unprecedented) subject-based limitation on the
    initiative power.” They contend that if section 7465(c)(4) satisfies
    the single-subject rule, there is no basis to distinguish it from the
    rest of the initiative for purposes of the separation of powers
    analysis. But the Supreme Court in Kelly, supra, 47 Cal.4th at
    pages 1025–1026 and footnote 19, recognized the “related but
    distinct” standard and both the Supreme Court and the Courts of
    Appeal continue to apply it, so it is hardly undefined or
    unprecedented. (E.g., People v. Superior Court (Pearson), supra,
    48 Cal.4th at p. 573; People v. Steward (2021) 
    63 Cal.App.5th 895
    , 899.) In addition, the single-subject rule and the separation
    of powers are analytically distinct and serve different purposes,
    so there is no reason to allow the former to swallow the latter.
    The single-subject analysis intentionally “is applied ‘in an
    54
    accommodating and lenient manner so as not to unduly
    restrict . . . the people’s right to package provisions in a single bill
    or initiative.’ ” (Briggs, supra, 3 Cal.5th at p. 829.) By contrast,
    the separation of powers doctrine is intended to protect the
    Legislature’s sphere of control, to ensure that it “remains free to
    enact laws addressing the general subject matter of an initiative,
    or a ‘related but distinct area’ of law that an initiative measure
    ‘does not specifically authorize or prohibit.’ ” (Kelly, at p. 1026,
    fn. 19, italics omitted.) Our agreement with interveners that
    Proposition 22 complies with the single-subject rule does not free
    us of our obligation to enforce the separation of powers.
    Interveners further argue that prohibiting the voters from
    expressing their views on the types of legislation that would be
    subject to an initiative’s amendment process will discourage
    voters from allowing amendments at all in the future, but we are
    not convinced. Sections 7465(c)(3) and (4) are apparently unique
    in the annals of initiative statutes. Voters chose to permit
    amendments of initiatives for decades before Proposition 22. It
    seems likely they will continue do so even though we now declare
    sections 7465(c)(3) and (4) invalid. We also question whether
    voters allow the Legislature to amend their initiative measures
    as a sort of gift or a consolation prize, as interveners’ argument
    implies. Rather, voters likely permit amendments so that the
    Legislature can close loopholes, fix problems, and tweak initiative
    statutes to meet unexpected circumstances. Declaring sections
    7465(c)(3) and (4) to be unconstitutional attempts to expand
    55
    Proposition 22’s article II, section 10(c) shadow will not eliminate
    or reduce these incentives.
    For its part, the state at least reads sections 7465(c)(3)
    and (4) as exactly what they purport to be: attempts to define
    certain types of legislation that will constitute amendments of
    the initiative. But the state strays when it maintains that
    sections 7465(c)(3) and (4) are nonetheless proper. The state
    contends that legislation can amend an initiative even without
    altering its text and Proposition 22 regulates collective
    bargaining (albeit without saying so directly), so section
    7465(c)(4) appropriately declares that new legislation authorizing
    collective bargaining would change the initiative’s effect.17 The
    state believes Proposition 22 regulates app-based drivers’ ability
    to collectively bargain by classifying them as independent
    contractors, who, as a matter of law, cannot collectively bargain.
    The state does not meaningfully respond to plaintiffs’
    argument that sections 7465(c)(3) and (c)(4) interfere with the
    judiciary’s role to determine what constitutes an amendment
    within the meaning of article II, section 10(c). And the state’s
    attempt to rebut plaintiffs’ argument regarding section
    7465(c)(4)’s infringement on the Legislature’s powers is flawed.
    We have no quarrel with the principle that legislation can amend
    an initiative without expressly changing its wording, but that
    17 While the state treats section 7465(c)(4) as dealing only
    with collective bargaining, by its terms the provision would also
    apply to legislation authorizing other forms of representation of
    app-based drivers, including representation on an individual
    basis. (See fn. 13, ante.)
    56
    principle has no application here. As discussed ante, Proposition
    22 does not directly regulate collective bargaining. And as noted,
    independent contractors are not entirely barred from collectively
    bargaining, so long as the Legislature enacts a law that satisfies
    the requirements for state action immunity to antitrust law.
    Section 7465(c)(4) therefore extends more broadly than
    Proposition 22’s natural article II, section 10(c) shadow.
    Additionally, as several election law professors point out in an
    amicus brief, the voters would have had little reason to obliquely
    call out potential collective bargaining statutes in section
    7465(c)(4) as amendments to the initiative if Proposition 22’s
    substantive provisions already addressed that issue. If there
    were any doubt about whether the initiative’s classification of
    app-based drivers as independent contractors foreclosed the
    possibility of collective bargaining, the far more direct way to
    address the issue would be to add a provision expressly saying so.
    The only discernable reason to include section 7465(c)(4) was to
    expand the scope of the initiative’s article II, section 10(c) shadow
    beyond Proposition 22’s substantive provisions.
    In a variation on the state’s argument, interveners contend
    in their reply brief that we could interpret section 7465(c)(4) itself
    as a form of substantive regulation. In this view, because app-
    based drivers cannot collectively bargain in the absence of an
    authorizing statute and there is presently no such law, section
    7465(c)(4)’s restriction on the enactment of such a law effectively
    locks in place the status quo of drivers not being able to
    collectively bargain.
    57
    Treating section 7465(c)(4) as equivalent to a direct
    pronouncement that app-based drivers cannot collectively
    bargain presents even more difficulties than the other
    interpretations. To begin with, this approach is inconsistent with
    the text of the initiative. Section 7465(c)(4) is the only section
    contained in an article titled “Amendment.” (People v. Garfield
    (1985) 
    40 Cal.3d 192
    , 199 [titles are “a useful guide in
    determining the intended scope of legislation,” but not the only
    one].) And by its terms, section 7465(c)(4) discusses only the
    content of future legislation. It does not affirmatively state that
    app-based drivers cannot collectively bargain or that the
    Legislature cannot allow a public entity to represent them on an
    individual basis.
    Even if section 7465(c)(4)’s text could be read to imply that
    drivers may not collectively bargain, there is no indication that
    the voters intended section 7465(c)(4) to operate in this fashion.
    “ ‘ “[I]n the case of a voters’ initiative statute . . . we may not
    properly interpret the measure in a way that the electorate did
    not contemplate: the voters should get what they enacted, not
    more and not less.” ’ ” (People v. Valencia (2017) 
    3 Cal.5th 347
    ,
    375.) Section 7465(c)(4) does not use the phrase “collective
    bargaining,” even though all the parties here acknowledge that
    restricting collective bargaining was the provision’s aim. Nor
    does such an intent appear in Proposition 22’s prefatory findings
    and statements of purpose. The Attorney General did not
    identify such a restriction as one of the initiative’s effects, either
    in the original circulating title and summary or in the revised
    58
    title and summary included in the voter guide. (Proposition 22,
    at p. 2, available at
     [as of
    Mar. 13, 2023]; Voter Guide, supra, title and summary of Prop.
    22, p. 56.) Nor did the Legislative Analyst. (Voter Guide, supra,
    analysis of Prop. 22, pp. 56–57.) Nor did the arguments for and
    against the initiative.18 (Id. at pp. 58–59.)
    To paraphrase our Supreme Court’s remarks about a
    different initiative, “[w]e recognize that the materials in the
    ballot pamphlet may not touch on every aspect of an initiative, no
    18  Interveners ask us to judicially notice a tweet from the
    campaign against Proposition 22 and a webpage maintained by
    that campaign that they claim demonstrate the voters
    understood that Proposition 22 would affect app-based drivers’
    ability to collectively bargain. Assuming for the sake of
    argument that these materials are properly subject to notice,
    they do not change our analysis. These materials predicted that
    “Proposition 22 would make it almost impossible for workers to
    have legal protections if they want to collectively bargain.” But
    they did not describe whether this would come from classifying
    app-based drivers as independent contractors, thereby requiring
    an act by the Legislature to enable collective bargaining, or from
    the section 7465(c)(4) limitations on such legislation. The tweet
    and webpage therefore do not demonstrate that voters
    understood the effect of section 7465(c)(4).
    Interveners also ask us to notice a webpage from an online
    encyclopedia that they contend demonstrates that Proposition 22
    received widespread publicity and public discussion. This
    webpage was not submitted to the trial court, so we deny this
    request. (Haworth v. Superior Court (2010) 
    50 Cal.4th 372
    , 379,
    fn. 2 [“ ‘Reviewing courts generally do not take judicial notice of
    evidence not presented to the trial court’ absent exceptional
    circumstances”].) This webpage also does not demonstrate
    anything about which specific aspects of Proposition 22 received
    publicity or discussion.
    59
    matter how minor. ‘A statute, of course, must prevail over any
    summary. Were it not so, no statute could ever be enacted whole
    and entire. For every summary, by definition, is incomplete.’
    [Citation.] When, for example, an initiative contains a clear and
    unambiguous provision that, because of its relatively limited
    significance, is not mentioned in ballot summary or arguments,
    the absence of such a reference will not nullify its effectiveness.
    Here, however, the language of Proposition [22] is not free from
    ambiguity. And the application of its definition of [an
    amendment regulating app-drivers’ ability to collectively bargain]
    is a matter of such substantial import that the voters could
    reasonably expect that, if Proposition [22] applied [in such a
    way], the ballot materials would mention it.” (People v. Valencia,
    
    supra,
     3 Cal.5th at p. 364, fn. 6.)
    Finally, we are reluctant to accept section 7465(c)(4) as an
    indirect form of substantive regulation because of the troubling
    implications for the initiative process. Treating section
    7465(c)(4)’s ostensibly procedural regulation of the amendment
    process as equivalent to a direct statement that app-based
    drivers cannot collectively bargain would encourage
    gamesmanship and reward initiative proponents for drafting
    confusing, or even outright misleading, initiatives. Adhering to
    the plain text of initiatives’ enactments will instead help ensure
    that proponents draft clear and intelligible proposals for the
    voters’ consideration.
    The state and interveners emphasize that we must
    jealously guard the initiative power. But our duty to guard the
    60
    initiative power works both ways; “we guard this power with both
    sword and shield. We must not only protect against interference
    with its proper exercise, but must also strike down efforts to
    exploit the power for an improper purpose.” (Widders v.
    Furchtenicht (2008) 
    167 Cal.App.4th 769
    , 785.) We do the voters
    no favors by upholding a provision that either unconstitutionally
    intrudes on the powers of the judiciary and the Legislature or
    whose effect was unclear and not called to their attention.
    The state and interveners also invoke the doctrine of
    constitutional avoidance, asking us to resolve all doubts in favor
    of the validity of section 7465(c) and to construe it in a way that
    avoids constitutional conflicts. (California Redevelopment Assn.
    v. Matosantos (2011) 
    53 Cal.4th 231
    , 253 [courts avoid
    “constitutional conflicts whenever possible by construing
    legislative enactments strictly against the impairment of [courts’]
    constitutional jurisdiction”]; Briggs, 
    supra,
     3 Cal.5th at pp. 857–
    859 [construing plainly mandatory provision in initiative as
    directive, in part to avoid separation of powers concerns].) But
    this does not allow us to simply pretend that Proposition 22
    regulates collective bargaining, as the state suggests, when the
    text does not reasonably admit of such a construction. The
    doctrine of constitutional avoidance does not allow us to clothe
    the emperor in such a fashion.
    We could perhaps construe section 7465(c)(4) as precatory,
    as interveners urge, even though its plain language is to the
    contrary. (See Briggs, 
    supra,
     3 Cal.5th at pp. 857–859.) But that
    would not meaningfully change the result. If section 7465(c)(4)
    61
    were a mere declaration of the voters’ intent that the initiative
    forbids app-based drivers from collectively bargaining, it might
    survive constitutional scrutiny on its face. However, any court to
    examine the question of whether Proposition 22 actually restricts
    the Legislature’s authority to authorize collective bargaining
    would very likely disregard such a statement of intent, since
    nothing in the text of the rest of the initiative supports it, as
    discussed ante. (O.G. v. Superior Court, supra, 11 Cal.5th at
    p. 91 [“In discerning the purposes of a proposition, ‘we are guided
    by, but are not limited to, the general statement of purpose found
    in the initiative’ ”].) We see little reason to uphold section
    7465(c)(4) by using the fig leaf of construing it as precatory, when
    such a construction would render it just as ineffectual as
    declaring it facially invalid.
    In sum, we conclude that sections 7465(c)(3) and (4) are
    facially invalid on separation of powers grounds because they
    intrude on the judiciary’s authority to determine what constitutes
    an amendment to Proposition 22, and section 7465(c)(4) fails for
    the additional reason that it intrudes on the Legislature’s
    authority by artificially expanding Proposition 22’s article II,
    section 10(c) shadow. As the trial court ruled and the parties
    agree, the proper remedy for the separation of powers violation is
    to sever section 7465(c)(3) and (4) and allow the rest of
    Proposition 22 to remain in effect, as the voters indicated they
    wished. (§ 7467, subd. (a).)
    62
    DISPOSITION
    The judgment is affirmed to the extent it declared sections
    7465(c)(3) and (c)(4) invalid and to the extent the trial court
    retained jurisdiction to consider a motion for attorney fees under
    Code of Civil Procedure section 1021.5. In all other respects, the
    judgment is reversed. The matter is remanded to the trial court
    with instructions to enter a new judgment not inconsistent with
    this opinion. All parties shall bear their own costs on appeal.

    STREETER, J., Concurring and Dissenting.
    I.    Introduction
    I concur in Justice Brown’s opinion except for one key
    aspect of part II of her discussion for the majority addressing
    article XIV, section 4 of the California Constitution, which vests
    the Legislature with “plenary power, unlimited by any provision
    of this Constitution, to create, and enforce a complete system of
    workers’ compensation, by appropriate legislation . . . .”1 My
    disagreement on this point leads me to a different overall result.
    I would affirm the judgment, but I prefer to go further. I believe
    we must invalidate Proposition 222 in its entirety.
    All legislative power—whether exercised by the
    Legislature, or by the voters acting as “electors” when they enact
    an initiative statute—must abide by constitutional limits, federal
    and state. (In re Marriage Cases (2008) 
    43 Cal.4th 757
    , 851.)
    In addition to the article III, section 3 separation of powers
    problem identified by Justice Brown based on what she terms the
    “shadow” effect of the initiative (tying the hands of the
    Legislature in the distinct and unrelated area of collective
    bargaining representation), Proposition 22 violates the California
    Constitution on three other grounds as well.
    1 All further undesignated citations to constitutional
    articles and sections thereof are to the California Constitution.
    2Business & Professions Code, sections 7448–7467, as
    added by Proposition 22, approved by the voters, General
    Election (Nov. 3, 2020).
    1
    First, by undermining the “complete system of workers’
    compensation” that the people have expressly defined in article
    XIV, section 4, Proposition 22 constitutes a sub rosa attempt to
    amend the Constitution in the guise of statutory change. Second,
    article XIV, section 4, delegates to the Legislature—not the voter
    electors—specific lawmaking power to “create” and “enforce” a
    “complete system of workers’ compensation.” This case presents
    a direct conflict between the voter electors’ power to adopt
    initiative statutes and the Legislature’s power under article XIV,
    section 4, and on this record we must resolve that conflict in favor
    of the Legislature. So long as the Legislature has acted within
    the scope of its authority under article XIV, section 4, voter
    electors may not countermand a prior determination by the
    Legislature about what the Constitution requires. Third,
    Proposition 22 usurps a “core” or “essential” governmental
    function provided for in article XIV, section 4—judicial power—in
    violation of article III, section 3.
    II.   Proposition 22 Violates Article XIV, Section 4,
    in Two Respects
    Unlike the petitioners in Independent Energy Producers
    Assn. v. McPherson (2006) 
    38 Cal.4th 1020
     (McPherson),
    respondents do not argue that a specific constitutional grant of
    lawmaking authority to the Legislature categorically precludes
    any use of the initiative power to legislate on the subject
    addressed by that grant. Their complaint is different. They say
    Proposition 22 so fundamentally undermines the workers’
    compensation system the Legislature created prior to 1918 that it
    2
    transgresses article XIV, section 4, and thus could only have been
    adopted validly by ballot amendment to the Constitution.
    I believe the argument is well taken.
    Proposition 22 removes app-based drivers from the
    constitutionally mandated workers’ compensation system and
    substitutes a private accident insurance mandate. (Bus. & Prof.
    Code, §§ 7451, 7455, subd. (a).) The linchpin of Proposition 22 is
    the “independent contractor” definition in Business & Professions
    Code section 7451. Proposition 22 reversed the Legislature’s
    judgment on this issue3 by redefining the scope of “employment,”
    a term that is used in the language of article XIV, section 4. No
    one disputes that the effect of the “independent contractor”
    definition in Proposition 22 is to expel app-based drivers, as a
    class, from the “complete system of workers’ compensation”
    established by the Legislature more than a century ago. Because
    the basic architecture of that system was literally written into
    the Constitution in 1918, statutory changes to it must be closely
    scrutinized for compatibility with article XIV, section 4.
    Proposition 22 cannot withstand that scrutiny in two
    respects, the first detailed in parts II.A.–II.B. and the second in
    parts II.C.–II.D.
    3  See Assembly Bill No. 5 (2019–2020 Reg. Sess.) (Assembly
    Bill 5); former Labor Code § 2750.3, as added by Stats. 2019,
    ch. 296, § 2; repealed and transferred to Lab. Code, §§ 2775, 2785.
    3
    A. Certain “Basic Features” of the “Complete System of
    Workers’ Compensation” Mandated by Article XIV,
    Section 4, Cannot Be Revised by Statute
    Article XIV, section 4, by its express terms, defines in detail
    what must be in a “complete system of workers’ compensation,”
    and the new privatized scheme for app-based drivers falls far
    short. There are no safety and health provisions; no provisions
    for vocational training if a driver cannot return to work; no
    compensation provisions for permanent disability; and no
    provisions for an administrative body exercising judicial power to
    resolve disputes expeditiously, with direct review in the Court of
    Appeal. At best, app-based drivers are left with a breach of
    contract remedy for any deprivation of workplace accident
    benefits, and the value of even that is dubious since these
    workers (like so many these days) must sign form contracts that
    force them into arbitration, without access to judicial review.
    Proposition 22 also permanently withdraws the
    Legislature’s authority to address these deficiencies by restoring
    article XIV, section 4’s protections to this class of workers.
    It allows no legislative amendments unless passed by seven-
    eighths vote of both houses of the Legislature, and even then any
    amendment must be “consistent with, and further[] the purpose
    of [Proposition 22].” (Bus. & Prof. Code, § 7465, subd. (a).) It also
    provides that “[a]ny statute that amends Section 7451”—the
    provision that removes app-based drivers from the workers’
    compensation system (as well as from other worker protections)—
    “does not further the purposes of ” Proposition 22. (Bus. & Prof.
    4
    Code, § 7465, subd. (c)(2).) As a result, Proposition 22 not only
    adopts an incomplete system of workers’ compensation that fails
    to meet article XIV, section 4’s constitutional requirements, it
    prevents the Legislature from acting to rectify the situation.
    The Constitution, plainly read, prohibits all of this. It is
    well established that article XIV, section 4, places substantive
    limits on any exercise of legislative power, whether exercised by
    initiative statute or by enactment of the Legislature. The
    definition of “complete system of workers’ compensation” in
    article XIV, section 4, tracks the statutory workers’ compensation
    system that existed in 1918. As early as 1922, the Supreme
    Court made clear that the Legislature has no power to go beyond
    the pre-1918 scheme and create new elements of a “complete
    system of workmen’s compensation” not mentioned in the
    constitutional language. (Yosemite L. Co. v. Industrial Acc. Com.
    (1922) 
    187 Cal. 774
    , 780 (Yosemite Lumber) [construing former
    article XX, section 21, adopted in November 1918, later
    renumbered article XIV, section 4].)4 That foundational

    as article XIV, section 4, without substantive change in 1976.

    benefits in some cases; and (2) a 1974 amendment making the
    provision gender neutral, changing ‘workmen’ to ‘workers.’ ”].)

    limitation precludes any legislative attempt to revise the basic
    outline of the constitutionally mandated scheme for
    compensating workers injured or killed while engaged in
    “employment.”5
    Yosemite Lumber and other early cases applying this
    principle to what is now article XIV, section 4, have continuing
    force today. In the 1970’s and 1980’s the Supreme Court
    confirmed that, while legislation consistent with the
    constitutionally mandated pre-1918 statutory scheme is
    permissible, statutory revisions altering the “basic features” of
    the scheme are not. (Mathews v. Workmen’s Comp. Appeals Bd.
    (1972)

    , 734–735 (Mathews) [statute conditioning the
    right to compensation on the absence of willful misconduct held
    to be valid because it was consistent with “basic features” of the

    constitution, as amended in October, 1911, must be construed in
    the light of their meaning at the time of the adoption of the
    amendment, and cannot be extended by legislative definition, for
    such extension would, in effect, be an amendment of the
    constitution, if accepted as authoritative”); Employers’ Liability

    form in 1911. Though some of the terminology changed in the
    course of its evolution, the scheme was always founded on the
    existence of an “employment” relationship. Each iteration of the
    constitutional language, in 1911 and in 1918, uses the term
    “employment” to designate the boundary of who is covered and
    who is not.

    , 635; Dye v. Council of the
    City of Compton (1947)

    , 490; McMillan v.
    Siemon (1940) 
    36 Cal.App.2d 721
    , 725.) Thus, voter electors
    legislating by initiative, and the Legislature enacting statutes,
    can only act within the powers afforded to them by the people in
    article XIV, section 4.6
    6 To be sure, voter electors can always change the “basic
    features” of the pre-1918 system of workers’ compensation by
    ballot constitutional amendment. For example, former article
    XX, section 21, the precursor to article XIV, section 4, authorized
    the Legislature to create a system “to compensate . . . workers for
    injury or disability, and their dependents for death incurred or
    sustained by the said workers.” (Prop. 23, approved by the
    voters, Gen. Elec. (Nov. 5, 1918); Ballot Pamp. text of Prop. 23 at
     [as of Mar. 13, 2023].) The
    California Supreme Court held in 1922 that these words did not
    7
    What this means here, as a practical matter, is that there
    is a minimum constitutional baseline to our workers’
    compensation system no statute can go below. If, after adoption
    of article XIV, section 4—which codified in the Constitution itself
    what a “complete system of workers’ compensation” meant prior
    to 1918—the Legislature had attempted to create a different
    statutory scheme by lopping off some of the “basic features” of
    that system (Mathews, supra, 6 Cal.3d at p. 735), the statute
    would have been invalid. Nothing could be more “basic” to the
    system of workers’ compensation than the scope of the
    “employment” relationship. Because Proposition 22 attempts to
    redefine that term in a manner that is contrary to the laws of
    workplace accident protection as “those laws . . . have existed
    since 1911” (Mathews, at p. 735), I believe it is unconstitutional.
    B. Article XIV, Section 4, Has Continuing Vitality Today
    Insisting upon a narrow reading that gives article XIV,
    section 4, no contemporary substance at all, the Attorney General
    and the interveners (collectively, the Proposition 22 proponents)
    authorize payment of compensation benefits to a state fund if the
    worker died without dependents (Yosemite Lumber, supra,
    187 Cal. at p. 782), a holding that was later extended to
    invalidate awards to the estates of deceased workers (see
    Commercial Cas. Ins. Co. v. Industrial Acc. Com. (1930) 
    211 Cal. 210
    , 215). Many years later, the voters amended article XIV,
    section 4, to allow the Legislature to authorize payment of a
    compensation award for a worker who dies without dependents
    either to the state (Prop. 13, approved by the voters, Gen. Elec.
    (Nov. 7, 1972); see Six Flags, supra, 145 Cal.App.4th at p. 97), or
    to the worker’s estate (Prop. 14, approved by the voters, Prim.
    Elec. (June 8, 1976)).
    8
    cite Mathews for the idea that the only purpose of article XIV,
    section 4, was to provide constitutional armor against judicial
    invalidation by Lochner era courts.7 While there is a grain of
    truth to this line of argument, the Proposition 22 proponents take
    the idea too far. Our Supreme Court has indeed recognized that
    the “sole purpose” of article XIV, section 4, was to put to rest “all
    doubts” about the constitutionality of the existing statutory
    workers’ compensation scheme in 1918. (Mathews, supra,
    6 Cal.3d at p. 734; City and County of San Francisco v. Workers’
    Comp. Appeals Bd. (1978) 
    22 Cal.3d 103
    , 114.) But the Mathews
    court said nothing about Lochner or Lochnerism, and
    understandably so, because there is considerably more to the
    origin story of article XIV, section 4, than that.
    For proper perspective, some historical background is
    necessary. By 1918, our Legislature had passed three versions of
    a statutory workers’ compensation scheme, each building on the
    last one in sequence. These schemes—which were viewed as
    “radical,” even “revolutionary,” at the time (Western Indemnity
    Co. v. Pillsbury (1915) 
    170 Cal. 686
    , 692 (Western Indemnity I ))—
    eliminated employers’ common law tort defenses against
    employee workplace accident claims and created an
    administrative system for adjudicating and enforcing such claims
    on a no-fault liability basis. The first, passed in 1911 and known
    as the Roseville Act (Stats. 1911, ch. 399, §§ 1–31, pp. 796–806),
    7See Lochner v. New York (1905) 
    198 U.S. 45
    , disapproved,
    West Coast Hotel Co. v. Parrish (1937) 
    300 U.S. 379
    .
    9
    was purely voluntary; the second, passed in 1913 and known as
    the Boynton Act (Stats. 1913, ch. 176, §§ 1–92, pp. 279–320), was
    compulsory. Refinements were made in the “workmen’s
    compensation, insurance and safety act of 1917” (Stats. 1917,
    ch. 586, §§ 1–74, pp. 831–879 (the 1917 Act)), which partially
    repealed and restated the Boynton Act (1917 Act, at
    pp. 831–832).8 This series of enactments reflected the cumulative
    statutory evolution of the pre-1918 workers’ compensation
    system. These statutes are what the Mathews court refers to
    when it speaks of the “basic features of those laws as they have
    existed since 1911.” (Mathews, supra, 6 Cal. 3d at p. 735.)9
    Article XIV, section 4, evolved along a parallel path, also in
    two steps. First, by ballot initiative in 1911—in fact, at the same
    special election that brought us the powers of initiative,
    8 The current workers’ compensation statutory scheme
    appears in the Labor Code. (King v. CompPartners, Inc. (2018)
    
    5 Cal.5th 1039
    , 1046 [“First created more than a century ago,
    California’s workers’ compensation system is now governed by
    the Workers’ Compensation Act (WCA; Lab. Code, § 3200 et seq.),
    ‘a comprehensive statutory scheme governing compensation given
    to California employees for injuries incurred in the course and
    scope of their employment.’ ”].)
    9 The majority opinion appears to question whether the
    Mathews and Hustedt courts actually meant what they said in
    stating that the language of article XIV, section 4, codified the
    “basic features” of the pre-1918 statutory scheme. (Maj. opn.,
    ante, at p. 22, fn. 10.) But the constitutional language—which
    these courts were simply describing when they said article XIV,
    section 4, outlines the “basic features” of a “complete system of
    workers’ compensation” (Hustedt, supra, 30 Cal.3d at pp. 342–
    343, fns. 10 & 11)—speaks for itself.
    10
    referendum and recall—the voters laid a constitutional
    foundation for the Roseville Act by adding former article XX,
    section 21, to the Constitution. Framed in abbreviated language
    compared to what later became article XIV, section 4, as we now
    know it, that amendment gave the Legislature plenary power to
    create and enforce a system of liability without fault for workers
    injured in the workplace. Second, seven years later, in November
    1918, the Legislature by joint resolution proposed the adoption of
    an amendment to the 1911 version of former article XX,
    section 21 (Mathews, supra, 6 Cal.3d at p. 733), this time adding
    much greater specificity and detail. The 1918 amendment
    augmenting former article XX, section 21, is in all material
    respects what we now have in article XIV, section 4.
    The amended language adopted in 1918 delineates with
    particularity the Legislature’s authority to make “adequate
    provisions” for relieving workers and their families of the
    “consequences of any injury or death incurred or sustained by
    workmen in the course of their employment, irrespective of the
    fault of any party”; “full provision for securing safety in places of
    employment”; “full provision for such medical, surgical, hospital
    and other remedial treatment as is requisite to cure and relieve
    from the effects of such injury”; “full provision for adequate
    insurance coverage against liability to pay or furnish
    compensation”; “full provision for otherwise securing the payment
    of compensation”; and “full provision for vesting power, authority
    and jurisdiction in an administrative body with all the requisite
    governmental functions to determine any dispute or matter
    11
    arising under such legislation, . . .” (Former art. XX, § 21,
    amended by Prop. 23, Gen. Election (Nov. 5, 1918).)
    Of particular significance here—because this reflects the
    superior position article XIV, section 4, enjoys relative to other
    provisions within the Constitution, as well as the preeminent role
    the Legislature has in making “social public policy” pertaining to
    workers’ compensation vis-à-vis other governmental actors—the
    amended language makes clear for the first time that (1) the
    Legislature’s “plenary” power to do all of the above-listed things
    is “unlimited by any provision of this constitution” and (2) the
    “social public policy” reflected in the system of workers’
    compensation established by the Legislature pursuant to this
    authority is “binding upon all departments of the state
    government.” (Former art. XX, § 21, amended by Prop. 23, Gen.
    Election (Nov. 5, 1918).)
    Stepping back for a moment to understand why a second
    ballot amendment was necessary in 1918, we must look to case
    law developments. In 1915, our Supreme Court upheld the
    Boynton Act against constitutional attack in Western Indemnity I
    over a vigorous dissent by Justice Henshaw, who predicted that
    “the decision in this case will doubtless pass under the scrutiny of
    the supreme court of the United States” (Western Indemnity I,
    supra, 170 Cal. at p. 721 (dis. opn. of Henshaw, J.)). The
    Henshaw dissent in Western Indemnity I was wide-ranging.
    It attacked the Boynton Act as an unreasonable exercise of the
    police power—a classic Lochner-style substantive due process
    12
    argument10—but it raised equal protection and takings clause
    issues as well.11 A concurring opinion by Justice Shaw took the
    position that the no fault liability provisions of the Boynton Act
    were sustainable under the taxing power, but agreed that, in a
    case where an employee’s injury was brought about by his own
    negligence, the application of the Boynton Act would constitute
    “an attempt to take private property from the owner for the
    private use of another person . . . without lawful excuse or right
    and without compensation.” (Western Indemnity I, supra, at
    p. 735 (conc. opn. dubitante of Shaw, J., on rehg. den.)
    Perhaps most importantly, the concurrence and the dissent
    in Western Indemnity I together cast doubt on whether former
    article XX, section 21, provided adequate support for the Boynton
    Act as a matter of state law.12 Justice Henshaw, who saw the
    Boynton Act as an exercise in “socialistic paternalism” (Western
    10 Western Indemnity I, supra, 170 Cal. at pages 711–716;
    see Ives v. South Buffalo Ry. Co. (1911) 
    201 N.Y. 271
     citing and
    relying on Lochner v. New York, supra, 
    198 U.S. 45
    , disapproved,
    West Coast Hotel Co. v. Parrish, 
    supra,
     
    300 U.S. 379
    , to
    invalidate New York’s workers’ compensation statute.
    11 Western Indemnity I, supra, 170 Cal. at page 716 (the
    statute is “obnoxious to the constitutional provisions
    guaranteeing equal protection . . . and forbidding confiscation”).
    12 Western Indemnity I, supra, 170 Cal. at page 729
    (dis. opn. of Henshaw, J.) (Boynton Act exceeds the Legislature’s
    powers under former article XX, section 21, as adopted in 1911);
    cf. Western Indemnity I, at page 735 (conc. opn. dubitante of
    Shaw, J., on rehg. den.) (combination of taxing power and police
    power insufficient to save Boynton Act from constitutional
    invalidity where employee fault implicated in his own injury).
    13
    Indemnity I, supra, 170 Cal. at p. 724), articulated this view most
    forcefully. His dissent hammered away at the theme that the
    basis for the Boynton Act was not an exercise of the police power
    at all, but instead was an unbridled expression of sovereign “fiat”
    (Western Indemnity I, at p. 710 (dis. opn. of Henshaw, J.)) that
    “places upon the employer, to the peril of his welfare and the loss
    of all his property, the performance of a duty resting upon the
    state itself.” (Id. at p. 723.) According to Justice Henshaw, the
    “[l]egislature mistakenly put on this constitutional grant” a vast
    and oppressive power that went well beyond its “declared limits.”
    (Id. at p. 729.)
    This backdrop in the California Supreme Court is
    important here, but just as relevant are developments prior to
    1918 in the United States Supreme Court. While concerns about
    potential constitutional invalidation as a matter of substantive
    due process under the United States Constitution were real in
    1915, as Justice Henshaw’s dissent demonstrates, those concerns
    had largely evaporated by 1918. The prediction of a grant of
    certiorari in Western Indemnity I did not come true, and in a trio
    of cases decided in the high court’s 1917 term, that court
    addressed—and rejected—Lochner challenges to statutory
    workers’ compensation systems of different kinds. (See Mountain
    Timber Co. v. State of Washington (1917) 
    243 U.S. 219
     [voluntary
    scheme]; Hawkins v. Bleakly (1917) 
    243 U.S. 210
     [voluntary
    scheme]; New York Cent. R. Co. v. White (1917) 
    243 U.S. 188
    14
    [compulsory scheme].) White, in particular, was a turning point,
    since it dealt with a compulsory scheme similar to California’s.13
    At both the federal and state level, what this brief review of
    the pertinent case law shows is that, by the time the proposed
    amendment to revise former article XX, section 21, came on the
    ballot in November 1918, it was not Lochner that cast
    constitutional doubt on California’s statutory workers’
    compensation scheme. Rather, the source of doubt was the split
    of opinion in Western Indemnity I over the adequacy of former
    article XX, section 21, as a state constitutional foundation for
    California’s workers’ compensation scheme. Given the state of
    the law at the time, the 1918 amendment sought to bolster and
    enhance the language of former article XX, section 21, as
    originally adopted in 1911, in direct response to the Henshaw
    view that that grant of lawmaking power was limitless and
    unbounded. The objective was to anchor article XIV, section 4,
    13     Following the decisions in these cases, in June of 1919
    the high court brushed aside another attempt to challenge a state
    workers’ compensation statute on substantive due process
    grounds with the following words: “In view of our recent
    decisions sustaining state laws imposing upon employers in the
    hazardous industries responsibility in one form or another for the
    consequences of injuries received by employees in the course of
    the employment in the absence of fault on the employer’s part
    . . . , little need now be said.” (New York Cent. R. Co. v. Bianc
    (1919) 
    250 U.S. 596
    , 601 [citing New York Cent. R. Co. v. White,
    
    supra,
     
    243 U.S. 188
     and Mountain Timber Co. v. State of
    Washington, supra, 
    243 U.S. 219
    , among other cases].)
    15
    more strongly in our Constitution, independently of the police
    power.14
    Accordingly, while it is true that the purpose of the 1918
    amendment was to “remove all doubts as to the constitutionality
    of then existing workmen’s compensation laws” (Mathews, supra,
    6 Cal.3d at p. 733)—a remark which must be understood against
    the backdrop of what the remaining doubts were when voters
    went to the polls—it is an overstatement to go a step further and
    suggest that the demise of Lochnerism in the mid-1930’s
    transformed article XIV, section 4, into a constitutional dead
    letter. In service of an argument that article XIV, section 4, may
    safely be ignored today, that account of what happened places a
    convenient expiration date on this provision of the Constitution.
    But it is incomplete and misleading as history.
    For proof, we need look no further than the cases
    construing article XIV, section 4, to put substantive limitations
    14 In the modern terminology of United States Supreme
    Court jurisdiction, this would be called an effort to insulate the
    decision in Western Indemnity I against federal constitutional
    attack—on any ground—by ensuring that the vehicle for such a
    future challenge would be a California decision resting on
    “adequate and independent state grounds.” (E.g., Republican
    Nat. Committee v. Burton (1982) 
    455 U.S. 1301
    , 1302.) As a
    recipe to ward off federal review, this is not a theory I am reading
    into the case law based on hindsight. It is a strategy that
    actually played out in a case involving Arizona’s workers’
    compensation scheme, where, just as we see with article XIV,
    section 4, the challenged statute was based on a specific grant of
    lawmaking power in that state’s constitution. (See Arizona
    Employers’ Liability Cases (1919) 
    250 U.S. 400
    , 417–419.)
    16
    on legislative power, dating from as early as 1922 (Yosemite
    Lumber, supra, 
    187 Cal. 774
    ) to as recently as 1981 (Hustedt,
    supra, 
    30 Cal.3d 329
    ) and even more recently, 2006 (Six Flags,
    supra, 
    145 Cal.App.4th 91
    ), long after Lochner was gone. If we
    take stock of the full history, article XIV, section 4, remains as
    vital today as it was when adopted in 1918. It should be treated
    with the seriousness and dignity it deserves as one of several
    enduring constitutional achievements of the progressive reform
    era, along with and adjacent to the powers of direct democracy.
    Here, what that means is we must stand ready to strike down
    any statute that exceeds the outer limits of legislative power
    established by article XIV, section 4. I believe Proposition 22
    crosses that line.
    C. This Case Presents the Conflict of Legislative Powers
    Issue Anticipated in Footnote 9 of the Supreme
    Court’s Opinion in Independent Energy Producers
    Assn. v. McPherson
    1. The Conflict Here Is Between Concurrent Powers,
    Not Coextensive Powers
    Although the most glaring constitutional violation
    presented here is the use of a ballot initiative to effect what
    amounts to an amendment of the Constitution, a second, related
    article XIV, section 4, violation requires the invalidation of
    Proposition 22.
    By placing the eligibility of app-based drivers for workers’
    compensation benefits off-limits to amendment by the
    Legislature, Proposition 22 seeks to override constitutional
    responsibility delegated to the Legislature. The Proposition 22
    17
    proponents contend that, in striking the initiative down on that
    basis, the trial court erred by construing the term “plenary” as
    “exclusive.” This is not an accurate characterization of the trial
    court’s ruling. The trial court saw a conflict between article XIV,
    section 4, and article II, section 10(c), and resolved it in favor of
    the Legislature. I believe it was correct to do so.
    The deficiency I see here is structural. The delegated
    power we are dealing with—the power to carry out a specific
    constitutional task (i.e., to establish and maintain a “complete
    system of workers’ compensation”)—was conferred on “the
    Legislature” under article XIV, section 4, not on the voters acting
    as “electors.” Because voter “electors” and the “Legislature”
    share the police power, they may each legislate on the subject of
    workers’ compensation, which is why our Supreme Court has
    held that the article II, section 8(a) power to adopt initiative
    statutes is “encompass[ed]” within the Legislature’s article XIV,
    section 4 power. (McPherson, supra, 38 Cal.4th at p. 1025.)
    But as the trial court correctly concluded, when voter
    electors exercise the police power in a way that comes into
    conflict with the Legislature’s article XIV, section 4, power, we
    have the dilemma the Supreme Court flagged in footnote 9 of its
    McPherson opinion. (McPherson, supra, 38 Cal.4th at p. 1044,
    fn. 9.) In that footnote, the court carefully left open issues that
    may be raised in a scenario where an initiative statute
    “improperly conflicts with the Legislature’s exercise of its
    authority” under a specific delegation of legislative power in the
    Constitution. (McPherson, at p. 1044, fn. 9., original italics.)
    18
    Emphasizing that we must liberally construe the people’s
    “initiative power” (Legislature v. Eu (1991) 
    54 Cal.3d 492
    , 501)
    and “resolve any reasonable doubts in favor” of this right
    (Brosnahan v. Brown (1982) 
    32 Cal.3d 236
    , 241, italics omitted),
    the Proposition 22 proponents tell us there is no genuine conflict
    here because the legislative power of the voters is at least
    coextensive with and in some respects “greater than that of the
    Legislature” (Rossi v. Brown (1995) 
    9 Cal.4th 688
    , 704). But
    because we are dealing with a ballot statute that treads on a
    constitutionally delegated power assigned specifically to the
    Legislature, sweeping statements about the people’s “precious
    rights” of initiative (Amador Valley Joint Union High Sch. Dist.
    v. State Bd. of Equalization (1978) 
    22 Cal.3d 208
    , 248) provide
    little guidance.
    Precision is crucial. Voter electors are not the “people”
    when they legislate under article II, section 8(a). They exercise
    sovereign power as the “people” only when they approve ballot
    constitutional amendments. Although voter electors and the
    Legislature may both exercise the police power to pass
    legislation, and ordinarily the electors have the upper hand when
    both wish to legislate on the same subject (art. II, § 10(c); People
    v. Kelly (2010) 
    47 Cal.4th 1008
    ), this is not an ordinary case. The
    power exercised by voter electors under article II, section 8(a),
    and the power exercised by the Legislature under article XIV,
    section 4, overlap, but these two powers remain distinct, as the
    history of article XIV, section 4, recounted above shows. Nothing
    in McPherson holds to the contrary. The McPherson court
    19
    pointed out that the electors’ ability to adopt statutes by
    initiative is a “similar power” to that of the Legislature under
    article XII, section 5 (McPherson, supra, 38 Cal.4th at p. 1033),
    not that the electors are “the Legislature” when they legislate on
    workers’ compensation matters, having simply stepped into the
    shoes of the Legislature, clothed with article XII, section 5,
    authority.
    Because only the Legislature has the constitutional power
    to act “pursuant to” article XIV, section 4 (Graczyk v. Workers’
    Comp. Appeals Bd. (1986) 
    184 Cal.App.3d 997
    , 1008), I believe
    the most accurate way to describe these two powers when they
    conflict is that they are concurrent, not that they are coextensive.
    (See Youngstown Sheet & Tube Co. v. Sawyer (1952) 
    343 U.S. 579
    , 637–638 (Youngstown Sheet & Tube) (conc. opn. of
    Jackson, J.).) The friction generated by a direct clash of two
    concurrent legislative powers within our basic plan of
    government presents a rare and difficult constitutional question.
    One of these two sources of power must give way when they
    collide, and as I read it, footnote 9 of McPherson signals that the
    usual rules of deference to legislation adopted by ballot initiative
    may have to yield in the face of competing constitutional
    considerations. In my view, this is such a case.
    2. McPherson Provides the Backdrop
    Before delving further into the conflict of concurrent
    powers issue before us, some background discussion of
    McPherson is useful. At issue there was an initiative statute,
    20
    Proposition 80, that expanded the regulatory jurisdiction of the
    Public Utilities Commission (PUC). Article XII, section 5, gives
    the Legislature “plenary power” to confer “additional regulatory
    authority and jurisdiction” upon the PUC, and the question was
    whether that clause prevents the voters from expanding the
    PUC’s regulatory jurisdiction by statutory ballot initiative.
    (McPherson, supra, 38 Cal.4th at p. 1023.) The Court of Appeal
    said yes, holding that legislation by ballot initiative was
    preempted on all subject matter covered by article XII, section 5.
    (McPherson, at p. 1023.)
    The Supreme Court reversed. After canvassing its
    precedents, the court concluded, first, “long-standing California
    decisions establish[] that references in the California
    Constitution to the authority of the Legislature to enact specified
    legislation generally are interpreted to include the people’s
    reserved right to legislate through the initiative power”
    (McPherson, supra, 38 Cal.4th at p. 1043); and second, “in light of
    the background and purpose of the relevant language of article
    XII, section 5, . . . [the clause] does not preclude the people,
    through their exercise of the initiative process, from conferring
    additional powers or authority upon the PUC” (id. at pp. 1043–
    1044).
    The second step of the analysis in McPherson, laying out
    the historical backdrop to article XII, section 5, was key. At the
    time it was added to the Constitution in 1911, there was great
    concern that railroad companies exercised de facto control over
    many organs of state government, including the Railroad
    21
    Commission, the precursor to the PUC. (McPherson, supra,
    38 Cal.4th at pp. 1038–1039.) By controlling the membership of
    the Railroad Commission, the railroads managed to evade
    regulation of their rates. (Ibid.) The motivating purpose of the
    ballot initiative that became article XII, section 5, was to take
    membership control of the Railroad Commission away from the
    railroads and ensure that, going forward, the Railroad
    Commission had adequate regulatory authority to control
    railroad rates. (McPherson, at p. 1040.) The clause in article XII,
    section 5 conferring “plenary power” on the Legislature to grant
    “additional authority and jurisdiction” addressed the potential
    that, to ensure the Railroad Commission’s continued regulatory
    effectiveness, expanded regulatory authority might be needed in
    the future.
    When McPherson was decided in 2006, the regulatory
    target was different, but the overall purpose of article XII,
    section 5, was the same. Independent electric service providers
    (ESP’s) were then an important new source of electric power to
    the public grid, and utilities’ cost of power purchases from them
    was increasingly affecting rates to consumers. (McPherson,
    supra, 38 Cal.4th at pp. 1025–1027.) But ESP’s emerged in the
    1990’s as creatures of the energy deregulation movement and
    were unregulated, so the PUC had no rate-setting or enforcement
    control over them. (Ibid.) To fill the gap, Proposition 80
    extended the agency’s rate-setting and enforcement authority to
    ESP’s. (McPherson, at pp. 1025–1027.)
    22
    The Supreme Court concluded that this new grant of
    regulatory authority was consistent with the “origin and purpose”
    of article XII, section 5 (McPherson, supra, 38 Cal.4th at p. 1025):
    To ensure the continuing effectiveness of the Railroad
    Commission, and hence of its regulatory successor, the PUC.
    McPherson would have been a very different case—the type of
    case we have here—had Proposition 80, for example, removed the
    PUC’s statutory jurisdiction to regulate investor-owned utilities
    rather than added to it. That is why respondents invoke
    footnote 9 of the McPherson opinion. They argue that, while
    ballot statutes may be used to build upon and refine our
    constitutionally sanctioned “complete system of workers’
    compensation,” the power to legislate by initiative may not be
    used to undermine that system.
    The interveners deride respondents’ reading of McPherson
    as an attempt to create a “one-way ratchet” permitting additive
    revisions to our statutory workers’ compensation system, but not
    subtractions from it. What the interveners overlook, in my view,
    is that, structurally, our state Constitution supports respondents’
    reading much better than it does theirs. They are asking that we
    allow the voter electors to “undo” what the Legislature has done
    pursuant to its article XIV, section 4 powers, and at the same
    time bar the Legislature from restoring what the electors have
    taken away, even if a majority of the Legislature reads the
    Constitution to require it.
    We are not dealing simply with who gets the legislative last
    word. Because the issue of whether an app-based driver is an
    23
    employee or an independent contractor determines threshold
    eligibility for workers’ compensation, it is squarely within the
    heartland of lawmaking power conferred solely upon the
    Legislature in article XIV, section 4. By seeking to reserve all
    statutory lawmaking power for themselves on this issue, the
    Proposition 22 voter electors go well beyond a measure in which
    voter electors have told the Legislature not to tinker with their
    statute. This statutory initiative attempts to seize and
    permanently redistribute constitutional power in a manner that
    subverts article XIV, section 4, itself.
    Let me be concrete about the problem I see here.
    If, mindful of the robust support for the Proposition 22 in the
    November 2020 election, a majority of elected legislators
    understand it to be their solemn constitutional obligation under
    article XIV, section 4, to override the definition of “independent
    contractor” adopted by voter electors—none of whom took any
    oath to uphold the Constitution when they entered the voting
    booth—I believe these legislators should be free to do so,
    unimpeded by Proposition 22. Indeed, I believe that article XIV,
    section 4, entitles them to have the last word on that issue, since
    the definition of “independent contractor” in Proposition 22
    “would, in effect, be an amendment of the Constitution, if
    accepted as authoritative.” (PG&E, supra, 180 Cal. at p. 500.)
    For that reason alone, we must resolve the conflict of
    concurrent powers issue presented in this case in favor of the
    Legislature. And in doing so, we need not handle this conflict as
    a zero-sum showdown in which one of the two must nullify the
    24
    other. All we need do to resolve this case is recognize that we are
    in a “zone of twilight” (Youngstown Sheet & Tube, 
    supra,
     343 U.S.
    at p. 637 (conc. opn. of Jackson, J.) where both powers are
    operative, while resolving the conflict on this particular record
    based on a tie-breaking principle drawn from article XIV,
    section 4. In practical terms, what that means is simply this:
    When the electors choose to legislate on the topic of workers’
    compensation by ballot, they must do so in a manner that is
    consistent with any prior exercise of article XIV, section 4, power
    by the Legislature.
    Proposition 22 fails that test. The Legislature used its
    article XIV, section 4 power in passing Assembly Bill 5, which
    was enacted in 2019 to clarify that app-based drivers and
    couriers are included within the existing workers’ compensation
    and occupational health and safety systems. Because the
    Legislature had acted previously on this topic pursuant to article
    XIV, section 4, when Proposition 22 came to the ballot, and acted
    decisively, I believe the voter electors were required to respect
    what the Legislature had done and lacked power to countermand
    it. To borrow Justice Jackson’s famous phrasing, Proposition 22
    having been adopted in the face of the “expressed will” of the
    Legislature, the voters’ power to legislate by initiative on the
    same topic was at its “lowest ebb” in those circumstances
    (Youngstown Sheet & Tube, supra, 343 U.S. at p. 637), and must
    be deemed subordinate.
    Courts have recognized a number of implied limitations on
    the initiative powers. Although article XVIII, section 3, of the
    25
    Constitution expressly declares that it can be amended by
    initiative, the initiative cannot be used to revise the Constitution.
    For example, the power of statutory initiative cannot be used to
    order the Legislature to pass a resolution because article II,
    section 8(a) speaks only of the “adoption or rejection of
    ‘statutes.’ ” (American Federation of Labor v. Eu (1984) 
    36 Cal.3d 687
    , 708.) Nor can the power of statutory initiative be used to
    regulate the Legislature’s internal operations, because that
    would conflict with the express grant of power in article IV,
    section 7(a) authorizing the Legislature to run its own affairs.
    (People’s Advocate, Inc. v. Superior Court (1986) 
    181 Cal.App.3d 316
    , 327.) To this list, I believe we must add that the power of
    statutory initiative cannot be used to subvert an express
    constitutional power delegated to the Legislature, and to the
    Legislature alone. (Ibid. [“Only by means of an initiative
    constitutional amendment may the people modify or impinge
    upon the freedom of the Legislature to exercise its
    constitutionally granted powers.”].)
    D. Applying “The Relevant Constitutional Provision”
    (Article XIV, Section 4) to the Terms of the Statute
    Involved (Proposition 22)
    Although Justice Jackson’s Youngstown Sheet & Tube
    concurrent powers framework provides important analytical
    guidance for resolving the conflict of legislative powers problem
    before us—and answers the question presented here simply and
    easily when applied in light of cases recognizing certain implied
    limits on the initiative power—the specific mode of analysis must
    26
    come from McPherson, since in that case our Supreme Court laid
    the groundwork for us in a case that is unquestionably the closest
    analog to our own. Footnote 9 of the McPherson opinion states
    that, should a conflict of the kind it contemplates arise in some
    future case, the analysis will be governed by the “application of
    the relevant constitutional provision or provisions to the terms of
    the specific legislation at issue.” (McPherson, supra, 38 Cal.4th
    at p. 1044, fn. 9.)
    As I noted above, the independent contractor definition in
    Business & Professions Code section 7451 is the “specific
    legislation” at issue here. This provision overturns the
    Legislature’s judgment in Assembly Bill 5 that app-based drivers
    must be treated as employees until putative employers prove
    otherwise in case-by-case adjudication within the workers’
    compensation system. Because class-wide exclusion of app-based
    drivers from the workers’ compensation system is the main
    objective of Proposition 22—in direct conflict with Assembly
    Bill 5—the analysis under footnote 9 of the McPherson opinion
    turns on the language of article XIV, section 4.
    Settled principles of interpretation govern the inquiry.
    Because it is elementary that we avoid interpreting our
    Constitution in a manner that renders any of its provisions
    nugatory, inoperative or meaningless (Lungren v. Deukmejian
    (1988) 
    45 Cal.3d 727
    , 735), we must strive to give article XIV,
    section 4, meaning. To discern the intent of the people acting in
    their sovereign capacity in 1918—and not project our modern
    understanding in retrospect—we must apply “ ‘ “the same
    27
    principles that govern statutory construction.” [Citation.] Where
    a law is adopted by the voters, “their intent governs.” [Citation.]
    In determining that intent, “we turn first to the language of the
    statute, giving the words their ordinary meaning.” ’ ” (People v.
    Raybon (2021) 
    11 Cal.5th 1056
    , 1065.)
    If it is necessary to go beyond plain meaning and consider
    context, historical context is relevant, as our Supreme Court
    recognized in addressing the parameters of a similar
    constitutional provision, article XII, section 5, in McPherson.
    (See McPherson, supra, 38 Cal.4th at pp. 1039–1040.) And as
    with statutory construction, the language in question “ ‘must also
    be construed in the context of the statute as a whole and the
    overall statutory scheme. [Citation.] We apply a presumption, as
    we similarly do with regard to the Legislature, that the voters, in
    adopting an initiative, did so being “aware of existing laws at the
    time the initiative was enacted.” ’ ” (People v. Raybon, supra,
    11 Cal.5th at p. 1065.)
    1. Text: Detailed and expansive grant of power “unlimited
    by any provision of this Constitution” to “create” and
    “enforce” a “complete system of workers’ compensation”
    Applying these principles to article XIV, section 4, two
    things are immediately apparent. First, what is most striking
    textually about article XIV, section 4, is its detail and specificity.
    There is a reason for that. When “California joined a rapidly
    growing number of states in adopting . . . workmen’s
    compensation act[s]” in the early twentieth century (Mathews,
    28
    supra, 6 Cal.3d at p. 729),15 our state was one of only a small
    group that specified “definite forms of compensation laws” in its
    Constitution. (Schneider, The Law of Workmen’s Compensation
    (1922) Ch. 2, § 4, p. 10, fn. 5.)16 The Proposition 22 proponents
    largely ignore the specificity of the text, dealing with it
    dismissively by suggesting that article XIV, section 4, is archaic
    (which is incorrect, as I have noted above), and is in any event
    redundant to the police power (which is equally incorrect, as I
    have also noted above).
    The breadth of the constitutional language is also striking.
    Article XIV, section 4, grants “plenary” legislative power
    “unlimited by any provision of this Constitution.” (Art. XIV, § 4,
    italics added.) The Proposition 22 proponents contend a literal
    reading of this expansive language would lead to absurd results,
    for it would free the Legislature from constitutional constraints
    such as the gubernatorial veto. But that is a strawman
    15 See Fishback & Kantor, The Adoption of Workers’
    Compensation in the United States, 1900–1930 (1998) 41 J. Law
    & Econ. 305, 319, table 2 (listing 48 states that adopted workers’
    compensation statutes between 1910 and 1918); id. at p. 319
    (“ ‘No other kind of labor legislation gained such general
    acceptance in so brief a period in this country.’ ”).
    16See Dinan, Foreword: Court-Constraining Amendments
    and the State Constitutional Tradition (2007) 
    38 Rutgers L.J. 983
    , 995–996 (noting that constitutional provisions “guaranteeing
    the constitutionality of workers’ compensation programs” were
    adopted in New York, Ohio, Arizona, California, Vermont,
    Wyoming, Pennsylvania, and Texas); id. at p. 995 (describing
    these provisions as “court-preempting constitutional
    amendments”).
    29
    argument. The breadth of the grant is easily explained by the
    variety of constitutional objections that had been raised prior to
    1918. Due process objections were a concern, but not the only
    ones.
    Nor is there any need to read this language as giving the
    Legislature wholly unchecked power, which was the contention
    Justice Henshaw made in Western Indemnity I, as echoed by the
    Proposition 22 proponents here with their “absurd results”
    argument. Respondents readily concede the Legislature must
    pass “appropriate legislation” under article XIV, section 4, before
    its views are binding on anyone. Naturally, that requires
    adherence to all requisite procedures under article II, section 8,
    subject to gubernatorial veto. Without following those
    procedures, no bill the Legislature passes is binding on anyone.
    It is not law at all, and is certainly not “appropriate legislation.”
    Similarly, a statute that exceeds the Legislature’s authority
    under article XIV, section 4, would not be “appropriate
    legislation.”17
    Second, functionally, the constitutional text charges the
    Legislature with the responsibility not only to “create” a
    “complete system of workers’ compensation”—in effect, codifying
    in the Constitution itself the statutory system then in existence—
    The Proposition 22 proponents make no claim that
    17
    Assembly Bill 5 exceeded the Legislature’s authority under
    article XIV, section 4. Nor could they, since Assembly Bill 5
    simply codified the Supreme Court’s holding in Dynamex
    Operations West, Inc. v. Superior Court (2018) 
    4 Cal.5th 903
    (Dynamex).
    30
    but also to “enforce” that system “by appropriate legislation” in
    the years ahead, while making clear that the pre-1918 “social
    public policy” reflected in the Legislature’s “complete system of
    workers’ compensation” has constitutionally binding effect on
    “all departments of State government.” (Art. XIV, § 4, italics
    added.) There is nothing time-limited about any of this. Article
    XIV, section 4, gave the Legislature a constitutionally designated
    role in 1918, and that role continues today. Nowhere is there any
    hint or suggestion that voter electors may commandeer it by
    ballot statute.
    Here again, the Proposition 22 proponents respond with
    overstatement. In their view, any suggestion the Legislature has
    a singular role to play under article XIV, section 4, must mean an
    exclusive role—preemptive of action by any other governmental
    actors. As framed in McPherson, that was indeed the issue
    addressed, there in the context of article XII, section 5. But not
    here. Respondents make no attempt to read article XIV,
    section 4, so broadly that it would nullify the power to adopt
    initiative statutes or place the Legislature’s judgments beyond
    judicial review. Nor do I. What we are called upon to decide is
    whether, absent a constitutional amendment, the text of article
    XIV, section 4, requires “all departments of State government” to
    give deference to the Legislature’s specifically delegated power to
    “create” and “enforce” a “complete system of workers’
    compensation.” This is why I believe it is crucial to appreciate
    that we are dealing with two concurrent powers here, and that
    the clash between them on this record must be resolved by
    31
    examining whether we can discern in the text of article XIV,
    section 4, any preference for either of these two forms of statutory
    lawmaking when they are in conflict.
    I think the answer is yes, we can discern such a preference,
    and it is for lawmaking by the Legislature. The grant of
    lawmaking power in article XIV, section 4, is not self-executing.
    While voter electors passing an initiative statute have no duty to
    do anything—their lawmaking power is purely discretionary—
    article XIV, section 4, charges the Legislature with an ongoing
    responsibility to carry out and abide by the terms of a
    constitutional mandate. “[A]rticle XIV, section 4 . . . defin[es] the
    necessary provisions for a complete workers’ compensation
    system, and le[ft] it up to the Legislature to enact laws to give
    effect to each provision.” (Bautista v. State of California (2011)
    
    201 Cal.App.4th 716
    , 729; see 
    ibid.
     [“only the Legislature has
    constitutional authority to create and enact the workers’
    compensation system”].) This special role is not discretionary.
    Under article XIV, section 4, “[t]he Legislature must act to fulfill
    its constitutional mandate to create the workers’ compensation
    system, and the judicially enforceable rights are the laws it
    enacts.” (Bautista, at p. 729, italics added.)18 So long as the
    18 My colleagues observe that there is “no logical conflict
    between article XIV, section 4 needing implementing legislation
    and the voters retaining their initiative power in the same field”
    and that “both can coexist.” (Maj. opn., ante, at p. 14, fn. 7.)
    I have not suggested to the contrary. They seem to miss the
    point of my focus on the need for implementing legislation: The
    Legislature has a constitutional duty to act under article XIV,
    32
    Legislature acts within the boundaries of its authority under
    article XIV, section 4, its specially designated constitutional role
    demands deference.
    Just as with Youngstown Sheet & Tube, there is a federal
    model to draw upon here. This model reflects a great deal of
    accumulated judicial wisdom applying what are perhaps the most
    well-known implementing clauses in American constitutional
    law—Congress’s “power to enforce, by appropriate legislation, the
    provisions of ” the Fourteenth and Fifteenth Amendments. (U.S.
    Const., XIV Amend., § 5; XV Amend., § 2.) The high court has
    consistently held that “Congress’ judgment regarding exercise of
    its power to enforce the Fourteenth and Fifteenth Amendments
    warrants substantial deference.” (Shelby County v. Holder (2013)
    
    570 U.S. 529
    , 566 (dis. opn. of Ginsburg, J.).) It is true, of course,
    that Congress’ powers are limited by enumerated grants, while
    the police power is a general power to govern by legislative
    prescription and needs no affirmative grant. But that makes no
    difference. The lesson to be drawn from these venerable grants of
    Congressional authority is that a constitutionally conferred
    prospective enforcement power carries with it an ongoing
    responsibility to apply and determine the meaning of
    constitutional language when faced with changing conditions.
    Legislative judgment in discharging that constitutional
    responsibility merits substantial deference.
    section 4, while voters going to the polls do not. A conflict arises
    only if ballot electors seek to obstruct the Legislature from
    discharging its duty.
    33
    To protect the enforcement prerogatives given to the
    Legislature in article XIV, section 4, substantial deference is due
    here as well—and not just from courts, but also from ballot
    statute electors. Unless we treat ballot statute electors as
    somehow outside our basic plan of government, they are bound to
    give the Legislature deference, just as courts are. Giving the
    expansive constitutional text its plain meaning, I believe we
    should read article XIV, section 4, as a command that when the
    Legislature enacts “appropriate legislation” designed to
    implement the constitutionally mandated “complete system of
    workers’ compensation,” its judgment trumps that of unelected
    voter lawmakers in the face of a conflict. So understood, article
    XIV, section 4, does not oust voter electors of power to legislate on
    the topic of workers’ compensation; it simply requires them to
    respect prior determinations of the Legislature as to what the
    Constitution requires.
    2. Historical context: Augmentation of the original 1911
    amendment, former article XX, section 21, and
    significance of Western Indemnity I to the issue of
    pro tanto repeal
    The historical context surrounding the adoption of article
    XIV, section 4, supports this reading of the text. The original
    1911 amendment was relatively brief. It stated, simply: “The
    legislature may by appropriate legislation create and enforce a
    liability on the part of all employers to compensate their
    employees for any injury incurred by the said employees in the
    course of their employment irrespective of the fault of either
    34
    party. The legislature may provide for the settlement of any
    disputes arising under the legislation contemplated by this
    section, by arbitration, or by an industrial or accident board, by
    the courts, or by either any or all of these agencies, anything in
    this constitution to the contrary notwithstanding.” (Former
    art. XX, sec. 21, added by Prop. 10, Special Elec. (Oct. 10, 1911);
    Ballot Pamp. text of Prop. 10 at  [as of Mar. 13, 2023].)
    By the time the Legislature proposed an amendment to
    former article XX, section 21, in 1918, the 1917 Act and the
    Boynton Act together established the statutory workers’
    compensation scheme. These statutes marked the first time an
    act of the Legislature occupied any of the “zone of twilight” where
    two concurrent powers may operate, as Justice Jackson put it in
    his concurrence in Youngstown Sheet & Tube, supra, 343 U.S. at
    page 637. Had the voters adopted a workers’ compensation
    statute of their own as a replacement for the Roseville Act, or
    made some amendment to the 1917 Act or the Boynton Act by
    initiative statute prior to November 1918—before the then
    existing statutory scheme was given constitutional sanction—
    they would have had a free hand to legislate within the limits
    prescribed by article XIV, section 4, since their will would have
    been memorialized in the constitutional language. But that is
    not what happened. Instead, a century later we are faced with
    an effort to undermine the constitutionally sanctioned intent of
    the Legislature.
    35
    In Western Indemnity I, the Supreme Court held that the
    original 1911 version of former article XX, section 21 was enough
    to provide a constitutional foundation for the Boynton Act. But
    two Justices disagreed, as I have noted above. We may fairly and
    reasonably infer that, when asked to do so by the Legislature in
    1918, voters responded by placing a detailed description of the
    Boynton Act, as improved and refined in the 1917 Act, into the
    Constitution itself, thereby adopting as their own the
    Legislature’s pre-1918 interpretation of what it means to have a
    “complete system of workers’ compensation.” (Mathews, supra,
    6 Cal.3d at p. 733 [“The proposed amendment duplicated in large
    measure section 1 of the 1917 act”].) As the Mathews court
    explained, article XIV, section 4, was “ ‘a necessary amplification
    and definition of the constitutional authority vested in the
    legislature by the amendment to the Constitution adopted
    October 10, 1911, to enable the enactment of a complete plan of
    workmen’s compensation, which amendment failed to express
    sanction for the requisite scope of the enactment to make a
    complete and workable plan.’ ” (Mathews, supra, 6 Cal.3d at
    p. 733, fn. 11.)
    This 1918 grant of augmented power—the police power
    plus, if you will—could not have been reserved by the people in
    1911 because it did not exist yet. It placed the Legislature at the
    apex of a complex new administrative system that cut across all
    three branches of government, requiring regulation of workplace
    safety and workplace accident insurance, adjudication of claims,
    and ongoing assessment of the adequacy of medical treatment
    36
    and compensation. The broad array of responsibilities detailed in
    article XIV, section 4, required the exercise of quasi-legislative
    powers that only the Legislature could undertake.19 Ballot
    statute electors were—and still today are—constitutionally
    unable to fill the role. (American Federation of Labor v. Eu,
    
    supra,
     36 Cal.3d at p. 708 [article II, section 8(a), legislative
    “powers are limited . . . to the adoption or rejection of ‘statutes.”].)
    We may glean from this historical context that voters
    supporting the 1918 amplification of former article XX,
    section 21, intended that it be given priority over other provisions
    in the Constitution in the event of conflict. In addition to the
    singular role given to the Legislature, as facilitated by the
    binding effect clause and the language “unlimited by any
    provision of this Constitution”—two key features of the operative
    language that were added in 1918—there is another reason to
    draw this inference. These voters must be deemed to have been
    aware of the Supreme Court’s holding in Western Indemnity I
    that former article XX, section 21, as originally adopted, “worked
    a repeal, pro tanto, of any conflicting provision which may have
    been in force theretofore.” (Western Indemnity I, supra, 170 Cal.
    at p. 695.) It makes no sense that voters would have intended
    the 1918 version of former article XX, section 21, to have any
    19 Wilson v. Hidden Valley Mun. Water Dist. (1967)
    
    256 Cal.App.2d 271
    , 279 (“The Legislature and administrators
    exercising quasi-legislative powers commonly resort to the
    hearing procedure to uncover, at least in part, the facts necessary
    to arrive at a sound and fair legislative decision.”).
    37
    lesser priority than the original version upheld in Western
    Indemnity I.
    Not surprisingly, courts have faithfully recognized the
    position of relative superiority within the Constitution that the
    plain language of article XIV, section 4 requires. In an opinion
    that supplies the most recent evidence of article XIV, section 4’s
    continuing vitality today, a First District, Division One panel
    held only a few years ago that article XIV, section 4, “supersedes
    the state Constitution’s due process clause with respect to
    legislation passed under the Legislature’s plenary powers over
    the workers’ compensation system.” (Stevens v. Workers’ Comp.
    Appeals Bd. (2015) 
    241 Cal.App.4th 1074
    , 1093 (Stevens).)
    Stevens also held that article XIV, section 4, “trumps the
    separation of powers clause [art. III, § 3] under the state
    Constitution’s plain terms,” since article III, section 3, expressly
    contemplates exceptions stated within the Constitution itself.
    (Stevens, at p. 1092.) Notably, to support these holdings, the
    Stevens court cited implied pro tanto repeal cases that trace back
    to Western Indemnity I. (Stevens, at p. 1093.)20
    McPherson provides a useful point of contrast. Article XII,
    section 5, the plenary power clause at issue there—which
    20 Hustedt, supra, 30 Cal.3d at page 343 (“It is well
    established that the adoption of [Section 4] ‘effected a repeal pro
    tanto’ of any state constitutional provisions which conflicted with
    that amendment”); Greener v. Workers’ Comp. Appeals Bd. (1993)
    
    6 Cal.4th 1028
    , 1037, (article VI of the state Constitution
    governing courts’ jurisdiction inapplicable to extent Legislature
    has exercised its powers under Section 4).
    38
    includes no language equivalent to the binding effect clause or
    the “unlimited by any provision of this Constitution” language in
    article XIV, section 4—was another ballot constitutional
    amendment passed in the October 1911 special election.
    (McPherson, supra, 38 Cal.4th at p. 1042.) The McPherson court
    observed there was no reason to believe that, in October 1911,
    voters would have intended to limit their own power under a
    simultaneously adopted amendment giving them broad new
    authority to adopt initiative statutes. (Ibid.) By contrast, there
    is reason to believe that, in the event of a conflict between
    article II, section 8(a), and the later adopted article XIV,
    section 4, in 1918, the latter would prevail. That reason is this—
    between 1911 and 1918, the pro tanto repeal holding in Western
    Indemnity I was handed down and, as noted above, knowledge of
    it is chargeable to voters.21
    21 The parties argue the issue of implied pro tanto repeal at
    length. In my view, the plain language of article XIV, section 4,
    is abundantly clear on this issue, and there is no need to resort to
    extrinsic interpretative aids. But even if the text were
    ambiguous, the position taken by the Proposition 22 proponents
    to the contrary—embraced by my colleagues in their construction
    of article XIV, section 4—rests on “clear statement” cases decided
    long after 1918. (E.g., California Cannabis Coalition v. City of
    Upland (2017) 
    3 Cal.5th 924
    ; Kennedy Wholesale, Inc. v. State
    Bd. of Equalization (1991) 
    53 Cal.3d 245
    , 252.) Respondents
    correctly point out that these cases concern the issue whether
    procedural limitations not stated in article II, section 8(a), may
    be imported into it, which is not the issue here. But the more
    basic problem with the line of argument the Proposition 22
    proponents pursue on the issue of pro tanto repeal is that we
    must seek to discern contemporaneous voter intent in 1918, not
    39
    3. Structural context: The binding effect clause in
    article XIV, section 4, is unique
    Finally, we must consider the language of article XIV,
    section 4, within the context of the Constitution as a whole.
    Upon an overall examination of our state charter, article XIV,
    section 4, stands in sharp contrast to all other, similar provisions
    in the document. The Constitution gives the Legislature plenary
    power to do things in five places,22 none of them providing
    ongoing enforcement authority, and nowhere else have the people
    said in the charter document that other actors in state
    government are bound by a “social public policy” enacted by the
    Legislature under a specifically delegated implementation power.
    These features in the operative text are unique.
    The language “binding upon all departments of the State
    government” is particularly notable. The plain meaning of “all
    departments of State government” encompasses not only the
    judicial, legislative, and executive branches of government
    (Brydonjack v. State Bar (1929) 
    208 Cal. 439
    , 442), but county
    and local government as well (City of Sacramento v. Industrial
    Acc. Com. (1925) 
    74 Cal.App. 386
     (City of Sacramento)). As noted
    above, unless we treat voter legislators as somehow exogenous to
    voter intent based on tools and standards of interpretation that
    were unknown at the time. In November 1918, Western
    Indemnity I established the state of the law on the issue.
    22 In addition to article XIV, section 4, see article XII,
    section 5 (Public Utilities); article XVI, sections 11 and 17 (Public
    Finance); article XIII, section 8.5 (Taxation); article XI, section 5
    (Local Government).
    40
    our plan of government, they are encompassed within the phrase
    “all departments of the State Government” when they adopt
    ballot statutes. This leaves voter electors ample room to make
    discretionary policy choices by ballot statute in the field of
    workers’ compensation. While voter electors cannot stand in the
    shoes of the Legislature under article XIV, section 4, they can
    always serve as “shadow” lawmakers, exercising the police power
    to enact any workers’ compensation legislation they wish—so
    long as they respect prior “appropriate legislation” enacted by the
    Legislature in this special arena.
    Several of the amici supporting the Proposition 22
    proponents urge us to harmonize article XIV, section 4, and
    article II, section 8(a), powers by construing these two sources of
    legislative power in a manner that recognizes the Legislature and
    voter electors may share authority to act on the topic of workers’
    compensation. While I agree with that perspective in principle,
    Proposition 22 resists harmonization—unless we declare a naked
    preference for article II, section 8(a), which is ultimately what
    these amici invite us to do, invoking platitudinous statements
    about the importance of direct democracy, and ignoring the
    usurpation of the Legislature’s delegated article XIV, section 4
    power that this mode of “harmonization” implies. To resolve the
    conflict before us correctly, we must recognize that this case is
    one of a kind. By making its independent contractor definition
    unamendable, Proposition 22 effectively appoints voter electors
    the sole and exclusive expositors of what the constitutional term
    “employment” means, thereby displacing the Legislature entirely
    41
    on that topic. This feature of Proposition 22 simply cannot be
    reconciled with article XIV, section 4.
    All bets are off when it comes to ballot constitutional
    amendments, since voter electors exercise sovereign power in
    that context and may always substitute their judgment by
    adopting paramount law. Indeed, in the final analysis, that is
    what this case is about. Until and unless voter electors escalate
    things to the level of a proposed constitutional amendment, the
    Constitution expressly gives our elected Legislature a unique
    role—I believe the preeminent role—when statutes are enacted
    pursuant to article XIV, section 4.23 If, as of 1918, the California
    judiciary was bound by the Legislature’s pre-1918 interpretation
    of what constitutes a “complete system of workers’
    compensation”—in the sense courts were expected to give
    deference to the Legislature’s original judgment about the “basic
    features” of that system, just as the Supreme Court did in
    23 A commonly used metaphor in cases involving challenges
    to initiative measures is that the initiative power in article II,
    section 8(a) is “in essence a legislative battering ram which may
    be used to tear through the exasperating tangle of the traditional
    legislative procedure and strike directly toward the desired end.”
    (Amador Valley Joint Union High Sch. Dist. v. State Bd. of
    Equalization, 
    supra,
     22 Cal.3d at p. 228.) In statutory initiative
    cases, however, we must take care to consider whether, in some
    circumstances—depending on the constitutional provisions we
    are dealing with—“the exasperating tangle of the traditional
    legislative procedure” (ibid.) is better described as a deliberative
    process for resolving competing interests by compromise and
    accommodation that the people have affirmatively expressed a
    preference for using.
    42
    Western Indemnity I—then it seems to me voter electors passing
    initiative statutes were similarly bound, and are still bound
    today.
    Disagreeing with me on this point, the majority opinion
    points out that the binding effect clause “appears to have been
    intended only to mean that the workers’ compensation system
    applies to the state and local governments as employers.” (Maj.
    opn., ante, at p. 27.) For this idea, the majority cites dicta from
    Bautista v. State of California, supra, 
    201 Cal.App.4th 716
    , and
    City of Sacramento, supra, 
    74 Cal.App. 386
    . Neither of these
    cases holds, nor has any case ever held, that local governments
    are the only “departments of the State government” covered by
    the binding effect clause in article XIV, section 4. Nor do these
    cases give any reason for why the binding effect clause should be
    read as an implicit partial definition of “employer,” a term that
    appeared nowhere in the constitutional language and was
    already fully defined in the statutory scheme the voters ratified
    in 1918. (1917 Act, Stats. 1917, ch. 586 § 7.)24
    Of the two cases, only City of Sacramento—decided less
    than a decade after article XIV, section 4 was adopted—merits
    24 A notable difference between the language of former
    article XX, section 21, as originally adopted in 1911, and the
    language of former article XX, section 21, as amended in 1918,
    was that the 1911 version used the terms “employer” and
    “employee” (former art. XX, § 21, added by Prop. 10, Special Elec.
    (Oct. 10, 1911)), while the 1918 amended version omitted them
    (former art. XX, § 21, amended by Prop. 23, Gen. Elec. (Nov. 5,
    1918)), since by 1918 there were detailed definitions of those
    terms in the 1917 Act.
    43
    full discussion. That case is illuminating, though not for the
    reason my colleagues cite it. There, a city employer tried to
    invalidate death benefits awarded to the widow of one of its
    employees who was killed in the course of his employment.
    (City of Sacramento, supra, 74 Cal.App. at p. 387.) The city
    employer tried to argue the widow’s claim was “a matter purely
    within the jurisdiction and control of the city of which such
    persons may be officers or employees” (id. at p. 388), which today
    we would call the “home rule” doctrine, our state equivalent of
    federalism in the national government.
    The contention was that the “compensation” of municipal
    employees falls within the exclusive domain of local government
    under former article XI, section 8½ of the Constitution. (City of
    Sacramento, supra, 74 Cal.App. at pp. 387–388.) This was not an
    argument directed to whether the statutory reach of workers’
    compensation extends to municipalities as “employers” within the
    meaning of the 1917 Act, the operative statute at the time.
    Under the plain language of the 1917 Act, “[t]he term ‘employer’
    . . . shall be construed to mean . . . [t]he state, and each county,
    city and county, city, school district and all public corporations
    therein.” (1917 Act, Stats. 1917, ch. 586, § 7.) The statutory
    definition of “employer” was never mentioned, which confirms
    that there was no genuine issue at the time about whether cities
    were included in that term. Rather, the city employer advanced a
    jurisdictional argument that the Legislature had no
    constitutional power to address the “compensation” of local
    employees.
    44
    The Court of Appeal rejected the city employer’s attempt to
    circumvent the 1917 Act by constitutional interpretation, holding
    that the word “compensation” in former article XX, section 21, as
    amended in 1918 (and now included in article XIV, section 4) was
    not used “in the sense of meaning wages” (City of Sacramento,
    supra, 74 Cal.App. at p. 392), but rather “in the sense of making
    amends for losses sustained, or the paying of an indemnity or an
    equivalent, so far as it is possible to do so in money value, to
    those dependents who have suffered such losses” (id. at p. 395).
    Because the Legislature was given plenary power to enforce
    liability for workers’ compensation awards against “all persons,”
    the court held, the term “persons” included municipalities. (Ibid.)
    Unpersuaded by the municipal employer’s attempt to offer a
    reading of former article XX, section 21, that implicitly exempted
    it from the “complete system of workers’ compensation” the
    Legislature created, the court pointed out that a municipality is a
    “department[] of the state government” bound by the “ ‘social
    public policy’ ” codified in former article XX, section 21. (City of
    Sacramento, at p. 395.)
    In my view, the lesson to be drawn from City of Sacramento
    is this. What came before the court there—just as it does in this
    case—was an attempt to place an entire class of workers outside
    the workers’ compensation system based on a narrow
    construction of the Legislature’s constitutionally delegated power
    to create a “complete system of workers’ compensation” and
    enforce compensation awards against covered employers. The
    City of Sacramento court was alert to the evasion and relied in
    45
    part on the “social public policy” embodied in former article XX,
    section 21 to reject it. I regret that we have not been similarly
    alert to the constitutional evasion Proposition 22 represents. As
    “shadow” legislators, the Proposition 22 voter electors are
    similarly bound by the “social public policy” codified in article
    XIV, section 4, particularly after the Legislature expressed its
    view of how that “policy” applies in passing Assembly Bill 5.
    III.   Proposition 22 Violates Article III, Section 3
    A. A Dispute Resolution System Within the Judicial
    Branch Is a “Basic Feature” of the Pre-1918
    “Complete System of Workers’ Compensation”
    Among the “basic features” of the pre-1918 workers’
    compensation system set up by the Legislature were these three:
    (1) the definition of “employee” included “[e]very person in the
    service of an employer . . . under any appointment or contract of
    hire or apprenticeship, express or implied, oral or written,”25
    (2) a “ ‘contract of hire’ mean[t] a contract for personal services,
    as is indicated by the fact that the basis of compensation provided
    by the act is the amount of wages earned,”26 and (3) disputes over
    the employment status of wage-earning workers—including on
    the issue of whether they were employees or independent
    contractors—were to be decided by the Industrial Accident
    1917 Act, Statutes 1917, chapter 586, section 8(a);
    25
    Western Indemnity Co. v. Pillsbury (1916) 
    172 Cal. 807
    , 810
    (Western Indemnity II); Press Pub. Co. v. Industrial Acc. Com.
    (1922)

    , 119.

    page 119; Western Indemnity II, supra, 172 Cal. at page 810.
    46
    Commission (IAC), subject to judicial review in the Court of
    Appeal.27
    This last element—administrative resolution of workers’
    compensation claims, with review channeled directly into the
    Court of Appeal—was added in 1913, when the statutory workers’
    compensation scheme evolved from a purely voluntary system in
    the Roseville Act into a compulsory system in the Boynton Act.
    Designed to ensure expeditious resolution of claims by a decision
    maker imbued with judicial power, this feature of the Boynton
    Act has long been recognized by our Supreme Court as a “basic
    feature” of the pre-1918 workers’ compensation system. (Hustedt,
    supra, 30 Cal.3d at p. 343.)
    Article XIV, section 4, includes definitional language
    describing this dispute resolution process in detail. The first
    paragraph of article XIV, section 4, begins: The Legislature is
    empowered to make “full provision for vesting power, authority
    and jurisdiction in an administrative body with all the requisite
    governmental functions to determine any dispute or matter
    arising under such legislation, to the end that the administration
    of such legislation shall accomplish substantial justice in all cases
    expeditiously, inexpensively, and without incumbrance of any
    character.” (Art. XIV, § 4, italics added.) The second paragraph
    271917 Act, Statutes 1917, chapter 586, sections 17–19,
    65–67; PG&E, supra, 180 Cal. at page 499; see Murray v.
    Industrial Acc. Com. (1932) 
    216 Cal. 340
    , 344 (employer has
    burden of proof on whether worker is independent contractor);
    Drillon v. Industrial Acc. Com. (1941) 
    17 Cal.2d 346
    , 350 (same)
    (Drillon).
    47
    of article XIV, section 4, fleshes this out in more detail, and
    specifically provides that any administrative decisions “shall be
    subject to review by the appellate courts of this State.” (Ibid.,
    italics added.)
    In the pre-1918 statutory scheme, resolution of workers’
    compensation disputes was given to the IAC, and in some
    instances to appointed “referees” whose decisions it reviewed
    (Boynton Act, Stats. 1913, ch. 176, § 76),28 but the above-quoted
    constitutional language confirms that this statutorily defined
    mode of dispute resolution was understood, ultimately, to be
    lodged in the judicial branch of government. The Supreme Court
    so held in 1916. Upholding the constitutionality of the Boynton
    Act in Western Metal Supply Co. v. Pillsbury (1916) 
    172 Cal. 407
    ,
    the court rejected a claim that the use of an administrative
    agency for resolution of workers’ compensation claims
    “transcends constitutional limitations in attempting to vest in the
    [IAC] the power—asserted to be judicial in its nature—to assess
    compensation and award it to such dependents.” (Id. at p. 410.)
    28 Many years later, the Legislature enacted provisions
    permitting arbitration of workers’ compensation disputes in some
    instances. (Lab. Code, § 3201.5.) That arbitral scheme, however,
    remains within the same administrative system for workers’
    compensation that has existed since enactment of the Boynton
    Act, with judicial review available in the Courts of Appeal, and
    has been held to be consistent with article XIV, section 4. (Costa
    v. Workers’ Comp. Appeals Bd. (1998) 
    65 Cal.App.4th 1177
    ,
    1184–1186.) Our system of judicial arbitration (Code Civ. Proc.,
    § 1141.10 et seq; see Rivera v. Shivers (2020) 
    54 Cal.App.5th 82
    ,
    90), another arbitral scheme established by statute within the
    judicial branch of government, provides a rough analogy.
    48
    “[I]n exercising [its] . . . powers,” the Western Metal Supply court
    held, the IAC “is performing precisely the same functions that are
    performed by any court in passing upon questions brought before
    it.” (Id. at p. 412; see Yosemite Lumber, supra, 187 Cal. at p. 779
    [“The power to determine whether or not the liability referred to
    in the first paragraph of the above section and imposed by this
    law exists against any person is judicial power.”].)
    B. Proposition 22 Defeats or Impairs a “Core” or
    “Essential” Governmental Function
    It is not the change in the substantive law governing the
    issue of employee versus independent contractor status that
    concerns me here—I have addressed that issue above in
    discussing the conflict between concurrent article II, section 8(a),
    and article XIV, section 4, powers (see parts II.C.–II.D. above)—
    but, rather, I am focused on the dismantling of the
    constitutionally ratified workers’ compensation dispute resolution
    scheme that free-agent workers analogous to app-based drivers
    today were entitled to invoke in 1918. This aspect of
    Proposition 22 raises an independently fatal constitutional
    deficiency.
    Because the pre-1918 workers’ compensation system
    established by the Legislature called for the resolution of claims
    by an administrative agency exercising judicial power,
    Proposition 22 took away an adjudicative function that was
    constitutionally committed to the judicial branch in article XIV,
    section 4. It therefore violates article III, section 3, which states
    that, within our “triune” scheme of government (Lorraine v.
    49
    McComb (1934) 
    220 Cal. 753
    , 756), “[p]ersons charged with the
    exercise of one power may not exercise either of the others except
    as permitted by this Constitution” (art. III, § 3). Electors
    exercising the police power to adopt statutes as “shadow”
    legislators, as I have noted above, must qualify as “[p]ersons
    charged with the exercise of one power” within the meaning of
    article III, section 3. (Ibid.)
    If the Proposition 22 proponents are correct that the
    holding in McPherson should be extended and applied in this
    case, they run headlong into a separation of powers problem
    under article III, section 3. That is because, even assuming voter
    electors may exercise a “similar power” (McPherson, supra,
    38 Cal.4th at p. 1033) to that of the Legislature in a manner that
    permits them to legislate freely in the field of workers’
    compensation, without limitation—indeed, in derogation of the
    Legislature’s article XIV, section 4, power—there remains a
    critical difference. Voter electors exercising the police power to
    pass ballot statutes are subject to separation of powers
    constraints, while the Legislature in the exercise of its power
    under article XIV, section 4, is not. (Stevens, supra,
    241 Cal.App.4th at p. 1092.) Thus, in addition to the separation
    of powers violation identified by the majority opinion, another
    article III, section 3, problem comes to the forefront if the
    Proposition 22 proponents’ reading of McPherson is correct: By
    destroying a mode of dispute resolution that app-based drivers
    are entitled to utilize within the judicial branch of government,
    Proposition 22 unconstitutionally usurps judicial power.
    50
    To uphold this initiative would “defeat or materially
    impair” the exercise of a judicial function (Hustedt, supra,
    30 Cal.3d at p. 338) as well as its doctrinal cousin, the rule
    against impairment of “core” (Carmel Valley Fire Protection Dist.
    v. State of California (2001) 
    25 Cal.4th 287
    , 297) or “essential”
    (Butt v. State of California (1992) 
    4 Cal.4th 668
    , 700, fn. 26)
    governmental functions. As the Supreme Court explained many
    years ago in Brydonjack v. State Bar, supra, 208 Cal. at page 442:
    “The sum total of this matter is that the Legislature may put
    reasonable restrictions upon constitutional functions of the courts
    provided they do not defeat or materially impair the exercise of
    those functions.” Fair questions are often raised in cases
    involving this kind of constitutional issue as to whether the
    challenged infringement is of a power that may truly be
    considered “core” or “essential,” but in this case it seems to me
    those questions are answered by the simple fact that, as courts
    have long construed it, we are dealing with a power that is
    delineated in the constitutional text.
    The issue of whether a given worker under a contract for
    hire has the status of an employee or an independent contractor
    is a judicial question. The Supreme Court so held in Drillon,
    supra, 
    17 Cal.2d 346
    . At issue in Drillon was the employment
    status of one Claude Hooper, a thoroughbred racing jockey who,
    while free to work for any horse owner, raced a particular horse
    subject to guidance and instruction from the horse’s owner. (Id.
    at pp. 348–350.) The IAC concluded that Mr. Hooper was an
    51
    employee of the owner (id. at pp. 348–349), and the Supreme
    Court affirmed (id. at pp. 355–356).
    Faced with an argument from the employer that
    Mr. Hooper’s status was controlled by the rules of the horse-
    racing board promulgated pursuant to statute (Drillon, supra,
    17 Cal.2d at pp. 352–354), the court held that “the issue of
    whether or not a person is an employee or an independent
    contractor is a judicial question and not a legislative or executive
    one. Legislative and administrative regulations relating to the
    affairs of persons furnishing services to the persons to whom
    furnished cannot control the judicial branch of the government in
    its determination of that question.” (Id. at p. 355.) The same
    analysis applies here.
    The Attorney General argues that independent contractors
    were always “excluded” from workers’ compensation coverage,
    and that in Proposition 22 the voters simply changed the
    substantive law determining whether app-based drivers have
    that status. There was no such “exclusion”; one was not needed.
    Because independent contractor status is, and always was, the
    opposite of employee status, and because article XIV, section 4,
    today, as under its previous incarnation in former article XX,
    section 21, covers only workers in an “employment” relationship,
    independent contractors have always been outside the reach of
    our statutory workers’ compensation system. (PG&E, supra,
    180 Cal. at p. 500; Carstens v. Pillsbury (1916) 
    172 Cal. 572
    , 580.)
    That is nothing new, and it is not a matter of statutory
    “exclusion.”
    52
    The question here is not whether independent contractors
    per se are outside the system. It is whether app-based drivers, a
    category of wage workers that did not exist prior to 1918, may be
    expelled from the present-day workers’ compensation system by
    labelling them independent contractors, thereby depriving them
    of any ability to have their employment status determined within
    the system. Wage workers in the position of today’s app-based
    drivers (who kept driving during the pandemic at great personal
    risk to themselves and their families) have always been
    presumptively within the workers’ compensation system, which is
    why respondents cite Drillon. Neither the Attorney General nor
    the interveners discusses Drillon or offers any meaningful
    response to the point respondents make on the strength of it.
    The critical point Drillon illustrates is that, prior to 1918,
    independent contractor status was nothing more than an
    employer’s defense, subject to proof on a case-by-case basis in
    workers’ compensation proceedings before an administrative
    tribunal that exercised judicial power, subject to review in the
    Courts of Appeal. The 1917 Act defined the term “independent
    contractor” in the same way the Supreme Court applied the
    concept twenty-five years later in Drillon. That statute provided,
    “The term ‘independent contractor’ shall be taken to mean, for
    purposes of this act: Any person who renders service, other than
    manual labor, for a specified recompense for a specified result,
    under the control of his principal as to the result of his work only
    and not as to the means by which such result is accomplished.”
    53
    (1917 Act, Stats. 1917, ch. 586, § 8(b).) And the people gave
    constitutional sanction to this definition in 1918.
    In passing Assembly Bill 5, the Legislature codified the
    ABC test recognized in Dynamex, 
    supra,
     
    4 Cal.5th 903
    , as the
    general rule to test for employee versus independent contractor
    status under the “suffer or permit to work standard” (id. at
    pp. 965–967), “subject to a series of statutory exemptions” for
    various industries (People v. Uber Technologies, Inc. (2020)
    
    56 Cal.App.5th 266
    , 277, fn. 5). Under Assembly Bill 5, all
    putative employers must continue to litigate any issue of
    employee versus independent contractor status before the
    Workers’ Compensation Appeals Board, and ultimately in the
    Courts of Appeal if necessary. Assembly Bill 5 simply confirmed
    that, as a general matter, the ABC test for independent
    contractor status governs, except that the more complex, multi-
    factor Borello test governs in certain industries. Both tests are
    consistent with the 1917 Act’s “independent contractor” definition
    and the “suffer or permit” standard courts use to apply that
    definition.29
    29 Dynamex, 
    supra,
     4 Cal.5th at pages 961–962 (“[T]he
    suffer or permit to work standard, by expansively defining who is
    an employer, is intended to preclude a business from evading the
    prohibitions or responsibilities embodied in the relevant wage
    orders directly or indirectly—through indifference, negligence,
    intentional subterfuge, or misclassification. It is well
    established, under all of the varied standards that have been
    utilized for distinguishing employees and independent
    contractors, that a business cannot unilaterally determine a
    worker’s status simply by assigning the worker the label
    54
    Thus, in Assembly Bill 5 the Legislature did not remove
    any of the “exempted” industries from the workers’ compensation
    system entirely, which is the much more radical step that
    Proposition 22 takes. In the one situation prior to Proposition 22
    where the Legislature created an industry-specific definition of
    the term “independent contractor” (see Bus. & Prof. Code,
    § 10032, subd. (b) [certain real estate licensees]), there is an
    exception for workers’ compensation (ibid. [“For purposes of
    workers’ compensation the characterization of the relationship
    shall be governed by section 3200, and following, of the Labor
    Code”]).
    That makes Proposition 22 the first attempt in the history
    of California workers’ compensation to drop a class of wage
    workers in one industry entirely from the workers’ compensation
    system. A telltale sign of the constitutional questions raised by
    this bold and unprecedented move is that, under the new
    statutory definition of “independent contractor,” the eligibility of
    app-share drivers for workers’ compensation benefits is
    determined strictly by the employer’s unilateral designation in a
    form contract—contrary to the “suffer or permit” standard—
    ‘independent contractor’ or by requiring the worker, as a
    condition of hiring, to enter into a contract that designates the
    worker an independent contractor.”); id. at p. 944 (“[A]t the time
    the suffer or permit language was initially adopted as part of a
    wage order in 1916, such language ‘was already in use
    throughout the country in statutes regulating and prohibiting
    child labor (and occasionally that of women), having been
    recommended for that purpose in several model child labor laws
    published between 1904 and 1912.’ ”).
    55
    which effectively bars these drivers from seeking to have their
    “employment” status adjudicated by a decision maker within the
    judicial branch. The route is indirect, but the result is a violation
    of article III, section 3.
    IV.   The Argument That, in Proposition 22, Voter
    Electors Made a Garden-variety Policy Choice,
    Is Incorrect
    Pointing to the language in article XIV, section 4,
    empowering the Legislature to establish a “complete system of
    workers’ compensation” for “any or all . . . workers,” the
    Proposition 22 proponents contend that it was perfectly
    permissible to withdraw a segment of workers from the original
    statutory system by initiative statute, and to provide workplace
    accident benefits for that segment of workers in a new and
    different way.30 There is nothing of significance to see here, we
    30   The actual constitutional language quoted by the
    Proposition 22 proponents on this textual point is that the
    Legislature shall have the power to create and enforce a system
    of workers’ compensation “liability on the part of any or all
    persons”—in context, clearly meaning employers—“to compensate
    any or all of their workers”—in context, clearly meaning
    employees of said employers (hence the phrase “their workers”)—
    “for injury or disability, and their dependents for death incurred
    or sustained by the said workers in the course of their
    employment, irrespective of the fault of any party.” (Art. XIV,
    § 4, italics added.) It is a stretch to construe the phrase “any or
    all . . . workers” to refer broadly to statewide coverage, rather
    than, as the context more naturally suggests, to the coverage
    status of workers who may have been hired by a given employer,
    an issue that seems amenable to determination only on an
    employer-by-employer basis. But because the Proposition 22
    proponents’ “any or all . . . workers” argument is flawed for other,
    56
    are told, because the voter electors simply exercised a policy
    choice concerning whom to cover in the statutory workers’
    compensation system differently than the Legislature did.
    But this was no ordinary policy choice. Proposition 22
    overturned a constitutionally ratified “social public policy” choice
    the Legislature originally made in the Boynton Act and the 1917
    Act, and then reaffirmed in Assembly Bill 5 in the course of
    discharging its ongoing duty to implement the “complete system
    of workers’ compensation” prescribed by article XIV, section 4. It
    does not matter whether voter electors now have their own view,
    different from the Legislature’s view, of the appropriate statutory
    reach of that system. What is dispositive in the face of conflict on
    this issue is that, as conditions changed over time, the
    Legislature was specifically tasked with making the call based on
    its view of what the Constitution required, and its call must be
    respected.
    The “any or all . . . workers” language in article XIV,
    section 4, simply confirms that, by 1918, the Legislature had not
    covered all potentially eligible wage workers. The coverage of the
    statutory scheme improved considerably between 1911 and 1918,
    but it was not fully comprehensive. While the objective of moving
    from a voluntary system to a compulsory system was to extend
    the reach of the statutory scheme, the 1917 Act still fell short of
    universal coverage. The 1917 Act did not cover “casual” workers;
    more fundamental reasons, as explained below, I am willing to
    indulge arguendo the broader construction of these words that
    they put forth.
    57
    it did not cover “domestic” workers; and it did not cover
    “agricultural” workers.31 “Casual” workers were not considered
    wage workers under contracts for hire. They were either
    volunteers or nominally paid temporary workers, and their status
    as non-employees continues to be reflected in the Labor Code to
    this day.32
    Why the Legislature created express carveouts for
    “domestic” workers and “agricultural” workers is another story—
    and not a happy one, since these two groups consisted largely of
    workers of color—but what matters here is that the language
    “any or all . . . workers” was broad enough to do two things. It
    not only described the less-than-comprehensive coverage the
    31   1917 Act, Statutes 1917, chapter 586, section 8(a).
    32  See Labor Code, section 3352, subdivisions (a)(4), (a)(5),
    (a)(7), (a)(9), (a)(10) and (a)(11); Gund v. County of Trinity (2020)
    
    10 Cal.5th 503
    , 510 (“volunteers are typically not eligible” for
    workers’ compensation benefits). The Proposition 22 proponents
    cite Graczyk v. Workers’ Comp. Appeals Bd., 
    supra,
    184 Cal.App.3d 997
    , for the proposition that, because the
    workers’ compensation system is statutory, a ballot statute may
    be used to “withdraw” previously covered workers from the
    system. They misread Graczyk. At issue there was a statutory
    provision (former Lab. Code, § 3352, subd. (k)) added in 1981 to
    clarify that unpaid student athletes were not employees eligible
    for workers’ compensation. (Graczyk, at pp. 1001–1005.) Non-
    wage workers were not covered in 1917, and in 1981 the
    Legislature simply confirmed that this class of workers remained
    outside the system. Graczyk would be on point if Proposition 22
    simply clarified that casual carpool commuter drivers (the ones
    that disappeared in the COVID-19 pandemic, while paid app-
    based drivers kept working) are not covered by workers’
    compensation.
    58
    Legislature had enacted by 1918, but at the same time confirmed
    the Legislature’s authority—if it wished to exercise it—to allow
    further expansion in the future. The Legislature exercised that
    authority in 1959 for “agricultural” workers33 and again in 1975
    for “domestic” workers.34 Voter electors could have done the
    same thing by initiative statute. The holding in McPherson
    confirms that. The eventual inclusion of those disfavored groups
    was a mark of progress, but it did not throw open the original
    core of the “complete system of workers’ compensation” for later
    statutory revision. The holdings in Mathews and Hustedt confirm
    that.
    The Proposition 22 proponents cite various cases holding
    that the workers’ compensation system is statutory and that
    Statutes 1959, chapter 505, page 2466, section 1
    33
    (repealing statutory language carried over from the original
    exclusion in the 1917 Act of “any employee engaged in . . . in
    farm, dairy, agricultural, viticultural or horticultural labor, [or]
    in stock or poultry” work, then codified at former Labor Code
    section 3352 (Stats. 1937, ch. 90, § 3352(c), p. 267)); see S. G.
    Borello & Sons, Inc. v. Dept. of Industrial Relations (1989)
    
    48 Cal.3d 341

    circumstances in which agricultural workers may be considered
    employees).

    152 Cal.App.3d 720
    , 735 (after removal of the exclusion,
    addressing circumstances in which domestic workers may be
    considered employees).
    59
    courts have consistently rejected constitutional challenges when
    the Legislature has made changes to the system. (See, e.g.,
    Stevens, supra, 241 Cal.App.4th at pp. 1094–1096 [statute
    eliminating workers’ compensation board’s authority to
    determine medical necessity of treatment and vesting such
    authority in an independent medical review organization];
    Wal-Mart Stores, Inc. v. Workers’ Comp. Appeals Bd. (2003)
    
    112 Cal.App.4th 1435
     [statute limiting workers’ compensation
    liability for benefits payable to treat psychiatric injury to workers
    employed for more than six months, unless the injury was caused
    by a sudden and extraordinary employment condition, held to be
    consistent with article XIV, section 4].)
    These cases resolve nothing here. Courts have long
    recognized that the Legislature must be given wide berth to
    adjust and refine the workers’ compensation system to meet the
    needs of the day, a notion that is fully consistent with my reading
    of article XIV, section 4. (See Stevens, supra, 241 Cal.App.4th at
    p. 1096 [“it is not our place under the state Constitution to
    ‘second-guess the wisdom of the Legislature’ in making these
    determinations”]; Facundo-Guerrero v. Workers’ Comp. Appeals
    Bd. (2008) 
    163 Cal.App.4th 640
    , 651 [same].) No one disputes
    that statutory changes may be made to the workers’
    compensation system at any time if the Legislature determines
    changes are necessary to ensure its effectiveness. And by
    initiative statute, the voters may join in that ongoing project—
    since they, too, may legislate on the same topic—as long as they
    do so in a manner that is consistent with prior judgments of the
    60
    Legislature made by “appropriate legislation.” What is key is
    that no case in this line either holds that “basic features” of the
    pre-1918 workers’ compensation system may be eliminated by
    statute, or involves a direct conflict between an initiative statute
    and a statute passed by the Legislature.
    It is ironic that the Proposition 22 proponents rely on the
    phrase “any or all . . . workers” in support of their argument that
    the scope of statutory workers’ compensation may be freely
    expanded or contracted, accordion-like, without limit by statutory
    initiative. They now seek to justify for app-based drivers the
    same kind of second-class citizenship treatment that agricultural
    and domestic workers were given in the original policy debate
    over the reach of workers’ compensation coverage. The
    interveners are quite explicit about this. They point to the
    pre-1918 exclusion of agricultural and domestic workers as proof
    that app-based drivers may be statutorily excluded today. About
    that, all I will say is that the United States Supreme Court may
    be willing to read the federal Constitution in a manner that
    doubles down on the mistreatment of fellow citizens who were not
    considered “full and equal” when the Fourteenth Amendment
    was adopted (Dobbs v. Jackson Women’s Health Org. (2022)
    ___U.S.___ [
    142 S.Ct. 2228
    , 2329] (dis. opn. of Kagan, J.)), but in
    reading our state Constitution, I am not. These exclusions are a
    historical embarrassment, not a license to create new social
    hierarchies by statute.
    Which brings me back to footnote 9 in McPherson. Moved
    to do so by the same progressive reform movement that brought
    61
    us the powers of direct democracy, the Legislature made a
    fundamental choice to cover as many wage workers under
    contracts for hire as it could between 1911 and 1917. Many
    decades later, in Assembly Bill 5, the 2019 Legislature expressed
    its view that the inclusion of app-based drivers within the
    workers’ compensation system is required. As I see things, the
    Legislature’s determination—which represents its interpretation
    of what the term “employment” means for purposes of the
    “complete system of workers’ compensation” codified in article
    XIV, section 4—must prevail over that of the Proposition 22 voter
    electors. Voter electors retain ultimate power to override the
    Legislature, but in this context they must do so by constitutional
    amendment. (See Legislature v. Deukmejian (1983) 
    34 Cal.3d 658
    , 674 [“[I]t was at no time intended that . . . permissive
    legislation by direct vote should override the other safeguards of
    the constitution. If an amendment of the constitution were
    intended, the provision requires steps to be taken that will
    apprise the voters thereof so that they may intelligently judge of
    the fitness of such measure as a constituent part of the organic
    law.”].)
    V.    Conclusion
    “[I]f any portion, section, subdivision, paragraph, clause,
    sentence, phrase, word, or application of ” Business and
    Professions Code section 7451—the “independent contractor”
    definition adopted in Proposition 22—“is for any reason held to be
    invalid by a decision of any court of competent jurisdiction, that
    decision shall apply to the entirety of the remaining provisions of
    62
    this chapter, and no provision of this chapter shall be deemed
    valid or given force of law.” (Bus. & Prof. Code, § 7467, subd. (b).)
    I believe the “independent contractor” definition in Proposition 22
    is constitutionally infirm and that, as a result, the entire
    initiative by its own terms must fall.
    It is undoubtedly true that “[t]he amendment of the
    California Constitution in 1911 to provide for the initiative and
    referendum signifies one of the outstanding achievements of the
    progressive movement of the early 1900’s.” (Associated Home
    Builders etc., Inc. v. City of Livermore (1976) 
    18 Cal.3d 582
    , 591.)
    But article XIV, section 4, was another outstanding achievement
    of progressive era reform, and it must be treated with equal
    dignity.
    In article XIV, section 4, the people gave constitutional
    sanction to an elaborate, pre-1918 statutory workers’
    compensation scheme. To implement the scheme, they conferred
    plenary power on the Legislature, and the Legislature alone.
    This expansive and singular delegation of authority, a species of
    power that may be found nowhere else in our charter document,
    is “unlimited by any provision of [the] . . . Constitution,” and
    imposes on the Legislature an ongoing duty of enforcement. (Art.
    XIV, § 4.) The pre-1918 statutory scheme itself, together with
    “appropriate legislation” enacted from time to time pursuant to
    the Legislature’s enforcement power, reflects a “social public
    policy” that is “binding upon all departments of the state
    government.” (Ibid.)
    63
    The central dilemma posed by this case is that
    Proposition 22 flies in the face of the Legislature’s declared
    “social public policy” in the field of workers’ compensation, as
    most recently reflected in its enactment of Assembly Bill 5. An
    integral part of the workers’ compensation system the
    Legislature has been implementing for more than a century
    pursuant to its article XIV, section 4, power is that, with two
    exceptions that were long ago eliminated, all wage workers are
    entitled to have their employment status determined by decision
    makers exercising judicial power.
    By jettisoning app-based drivers from this constitutionally
    mandated system, the independent contractor definition in
    Proposition 22 not only violates the plain terms of article XIV,
    section 4—because the system that remains is not “complete,” as
    the Legislature construed this constitutional requirement in the
    pre-1918 system—but conflicts directly with the Legislature’s
    recent exercise of its article XIV, section 4, power in Assembly
    Bill 5. For both of these reasons, Proposition 22 must be
    invalidated as violative of article XIV, section 4. And because
    Proposition 22 destroys the ability of app-based drivers to have
    their employment status determined within the judicial branch of
    government, it must also be invalidated as violative of article III,
    section 3.
    I would affirm in all respects.
