  •          IN THE SUPREME COURT OF
    CALIFORNIA
    JESSICA MILLAN PATTERSON et al.,
    Petitioners,
    v.
    ALEX PADILLA,
    as Secretary of State, etc.,
    Respondent.
    S257302
    November 21, 2019
    Chief Justice Cantil-Sakauye authored the opinion of the
    Court, in which Justices Chin, Corrigan, Liu, Cuéllar, Kruger
    and Groban concurred.
    Justice Cuéllar filed a concurring opinion.
    PATTERSON v. PADILLA
    S257302
    Opinion of the Court by Cantil-Sakauye, C. J.
    We must decide in this case whether portions of the
    recently enacted Presidential Tax Transparency and
    Accountability Act (Elec. Code, § 6880 et seq.) (the Act) conflict
    with article II, section 5, subdivision (c) of the California
    Constitution (article II, section 5(c)) and are therefore invalid.
    At issue are the Act’s provisions that prohibit the Secretary of
    State from printing on a primary election ballot the name of a
    candidate for President of the United States who has not filed
    with the Secretary of State the candidate’s federal income tax
    returns for the five most recent taxable years. Because of the
    important and time-sensitive nature of this controversy, we
    have exercised our original jurisdiction to entertain an
    emergency petition for a writ of mandate that would forbid the
    Secretary of State from enforcing the pertinent sections of the
    Act. Upon issuing an order to show cause, we directed the
    parties to submit briefing on an expedited basis to ensure the
    matter would be decided ahead of the November 26, 2019
    statutory deadline for candidates to disclose their tax returns to
    appear on the March 3, 2020 primary ballot.1
    1
    Several lawsuits pending in federal court assert that the
    provisions of the Act that are at issue here also violate federal
    law. Last month, the United States District Court for the
    Eastern District of California issued an order granting the
    federal plaintiffs’ request for a preliminary injunction that
    1
    PATTERSON v. PADILLA
    Opinion of the Court by Cantil-Sakauye, C. J.
    The dispute before us turns on the interpretation of
    article II, section 5(c), which states: “The Legislature shall
    provide for partisan elections for presidential candidates, and
    political party and party central committees, including an open
    presidential primary whereby the candidates on the ballot are
    those found by the Secretary of State to be recognized candidates
    throughout the nation or throughout California for the office of
    President of the United States, and those whose names are
    placed on the ballot by petition, but excluding any candidate
    who has withdrawn by filing an affidavit of noncandidacy.”
    (Italics added.)
    In requesting a writ of mandate, petitioners Jessica Millan
    Patterson and the California Republican Party (petitioners)
    assert that article II, section 5(c) requires a presidential primary
    prohibits the Secretary of State from enforcing these provisions.
    (Griffin v. Padilla (E.D.Cal., Oct. 2, 2019, No. 2:19-cv-01477-
    MCE-DB, No. 2:19-cv-01501-MCE-DB, No. 2:19-cv-01506-MCE-
    DB, No. 2:19-cv-01507-MCE-DB, No. 2:19-cv-01659-MCE-DB)
    __ F.Supp.3d __, __ [
    2019 WL 4863447
    , p. *1].) In so ruling, the
    federal court determined that the federal plaintiffs were likely
    to demonstrate that the challenged sections of the Elections
    Code violate the qualifications clause of the United States
    Constitution (U.S. Const., art. II, § 1, cl. 5), the First
    Amendment to the United States Constitution, and the equal
    protection clause of the Fourteenth Amendment to the United
    States Constitution; and that the provisions of the Act are
    preempted by the Ethics in Government Act of 1978 (5 U.S.C.A.
    Appen. 4, § 101 et seq). (Griffin, at p. __ [
    2019 WL 4863447
    ,
    pp. *8, *10, *11, *12].) The Secretary of State has appealed this
    ruling to the United States Court of Appeals for the Ninth
    Circuit.
    No federal claims are raised in the present case;
    petitioners’ sole argument is that the Act conflicts with article
    II, section 5(c).
    2
    PATTERSON v. PADILLA
    Opinion of the Court by Cantil-Sakauye, C. J.
    in which the names of all “recognized candidates throughout the
    nation or throughout California for the office of President of the
    United States” appear on the ballot. Petitioners cast the Act as
    unconstitutional because it imposes an additional disclosure
    requirement for appearing on a presidential primary ballot. In
    petitioners’ view, this additional prerequisite undermines the
    primary process contemplated by article II, section 5(c), and
    cannot lawfully be enforced.
    Secretary of State Alex Padilla, named as respondent,
    counters that article II, section 5(c) does not prevent the
    Legislature from prescribing disclosure prerequisites that even
    “recognized candidates throughout the nation or throughout
    California for the office of President of the United States” must
    satisfy if they are to appear on a presidential primary ballot. In
    respondent’s view, by stating that “[t]he Legislature shall
    provide for . . . an open presidential primary,” article II, section
    5(c) confirms that branch’s long-recognized, expansive authority
    to devise reasonable rules for primary elections, including
    presidential primaries. And subsumed within this power,
    respondent argues, is the authority to enact neutral disclosure
    laws that provide relevant information to voters and thus enable
    the electorate to make a more informed choice among
    presidential candidates.
    Upon careful consideration of the parties’ briefing and
    arguments, as well as the submission by amicus curiae, we
    conclude that petitioners are entitled to a writ of mandate. We
    direct the Secretary of State to refrain from enforcing Elections
    Code sections 6883 and 6884, the relevant provisions of the Act,
    insofar as enforcement of these sections would keep the name of
    a “recognized candidate[] throughout the nation or throughout
    California for the office of President of the United States” from
    3
    PATTERSON v. PADILLA
    Opinion of the Court by Cantil-Sakauye, C. J.
    being printed on the ballot of a political party that has qualified
    to participate in the primary election.
    As we shall explain, article II, section 5(c) is properly read
    as including a requirement that all persons found to be
    “recognized candidates” in the relevant sense must appear on
    the appropriate primary ballot, except when an affidavit of
    noncandidacy has been filed. This interpretation reflects the
    most natural reading of article II, section 5(c), and it vindicates
    the intent behind this provision. The language within article II,
    section 5(c) providing for the inclusion of “recognized”
    candidates on the primary ballot was added to the state
    Constitution through a June 1972 ballot measure, Proposition
    4. As the history of Proposition 4 makes clear, its purpose was
    to ensure that the voters at future California presidential
    primary elections would have the opportunity, within each
    qualifying political party, to choose among a complete array of
    candidates found to be “recognized candidates throughout the
    nation or throughout California for the office of President of the
    United States,” who had not filed affidavits of noncandidacy to
    remove themselves from the ballot.
    Elections Code sections 6883 and 6884 purport to make
    the appearance of a “recognized” candidate for president on a
    primary ballot contingent on whether the candidate has made
    the disclosures specified by the Act.            This additional
    requirement, however, is in conflict with the Constitution’s
    specification of an inclusive open presidential primary ballot.
    The Legislature may well be correct that a presidential
    candidate’s income tax returns could provide California voters
    with important information. But article II, section 5(c) embeds
    in the state Constitution the principle that, ultimately, it is the
    voters who must decide whether the refusal of a “recognized
    4
    PATTERSON v. PADILLA
    Opinion of the Court by Cantil-Sakauye, C. J.
    candidate[] throughout the nation or throughout California for
    the office of President of the United States” to make such
    information available to the public will have consequences at the
    ballot box.
    We therefore issue the writ of mandate.
    I. BACKGROUND
    We begin by describing the Act, and then review analyses
    of the measure that were prepared while it was still under
    consideration by the Legislature.            We then discuss
    contemporaneous legislation that was enacted earlier this year
    as Senate Bill No. 505 (2019-2020 Reg. Sess.) (Senate Bill
    No. 505). The latter statute is not directly at issue, but it is
    nevertheless relevant to the dispute before the court. The last
    portion of this background section will relate the brief history of
    this writ proceeding.
    A. The Presidential Tax Transparency and
    Accountability Act
    1. Senate Bill No. 27
    The Assembly and the Senate passed the Act in July 2019
    as Senate Bill No. 27 (2019-2020 Reg. Sess.) (Senate Bill No. 27),
    and the Governor signed the measure into law. As an urgency
    statute, the Act went into effect immediately “[i]n order to
    ensure that the protections” it affords “are in place for the 2020
    primary election.” (Stats. 2019, ch. 121, § 3.)2
    The Act directs the Secretary of State not to print on a
    primary ballot the names of candidates for President of the
    2
    The Act was not the Legislature’s first attempt to enact an
    income tax return disclosure requirement for presidential
    candidates. Senate Bill No. 149 (2017-2018 Reg. Sess.),
    5
    PATTERSON v. PADILLA
    Opinion of the Court by Cantil-Sakauye, C. J.
    United States or for Governor of California who have not filed
    their federal income tax returns with the Secretary of State.
    (Elec. Code, §§ 6883-6884, 8902-8903.) Because article II,
    section 5(c) relates only to the presidential primary ballot, only
    the provisions of the Act relating to candidates for president are
    implicated in this proceeding.
    Regarding candidates for president, the Act provides,
    “Notwithstanding any other law, the Secretary of State shall not
    print the name of a candidate for President of the United States
    on a primary election ballot, unless the candidate, no less than
    98 days before the presidential primary election, files with the
    Secretary of State copies of every income tax return the
    candidate filed with the Internal Revenue Service in the five
    most recent taxable years . . . .” (Elec. Code, § 6883, subd. (a).)3
    The candidate must file with the Secretary of State both
    unredacted and redacted versions of these returns, removing
    introduced in 2017, also would have required candidates for
    president to release their tax returns in order to be included on
    the primary ballot. (Id., as enrolled Sept. 20, 2017, § 1.) Both
    houses of the Legislature passed this measure, but as discussed
    post, the bill was vetoed by then-Governor Jerry Brown.
    3
    The statute addresses the possibility that a candidate may
    not have filed federal income tax returns for all five of the most
    recent taxable years. It provides, “If the candidate has not filed
    the candidate’s income tax return with the Internal Revenue
    Service for the tax year immediately preceding the primary
    election, the candidate shall submit a copy of the income tax
    return to the Secretary of State within five days of filing the
    return with the Internal Revenue Service” (Elec. Code, § 6883,
    subd. (b)), and, “The [disclosure] requirement . . . does not apply
    to any year in which the candidate was not required to file the
    candidate’s income tax return with the Internal Revenue
    Service” (id., subd. (c)).
    6
    PATTERSON v. PADILLA
    Opinion of the Court by Cantil-Sakauye, C. J.
    certain personal information such as social security numbers,
    home addresses, and medical information from the latter
    version. (Id., § 6884, subd. (a)(1).) The candidate also must file
    with the Secretary of State a signed written consent form that
    grants the Secretary of State permission to make a redacted
    version of the tax returns publicly available. (Id., subd. (a)(2).)
    Upon receiving the income tax returns, the Secretary of
    State is to review them to confirm that only the information
    identified by statute as subject to redaction has been removed.
    (Elec. Code, § 6884, subd. (b).) If additional redactions have
    been made to a tax return, “the Secretary of State shall prepare
    a new version of the tax return with only the redactions
    permitted by” statute. (Ibid.) Within five days of receiving a
    candidate’s tax returns, the Secretary of State shall make
    appropriately redacted versions of the returns available to the
    public on the Secretary’s website. (Id., subd. (c)(1), (2).) These
    versions “shall be continuously posted until the official canvass
    for the presidential primary election is completed.” (Id., subd.
    (c)(3); see also id., subd. (c)(4).)
    The Act includes the following findings and declarations
    regarding the income tax return disclosure requirement for
    presidential candidates: “The . . . State of California has a
    strong interest in ensuring that its voters make informed,
    educated choices in the voting booth. To this end, the state has
    mandated that extensive amounts of information be provided to
    voters, including county and state voter information guides.
    The Legislature also finds and declares that a Presidential
    candidate’s income tax returns provide voters with essential
    information regarding the candidate’s potential conflicts of
    interest, business dealings, financial status, and charitable
    donations. The information in tax returns therefore helps voters
    7
    PATTERSON v. PADILLA
    Opinion of the Court by Cantil-Sakauye, C. J.
    to make a more informed decision. The Legislature further finds
    and declares that as one of the largest centers of economic
    activity in the world, the State of California has a special
    interest in the President refraining from corrupt or self-
    enriching behaviors while in office. The people of California can
    better estimate the risks of any given Presidential candidate
    engaging in corruption or the appearance of corruption if they
    have access to candidates’ tax returns. Finally, the State of
    California has an interest in ensuring that any violations of the
    Foreign Emoluments Clause of the United States Constitution
    or statutory prohibitions on behavior such as insider trading are
    detected and punished. Mandated disclosure of Presidential
    candidates’ tax returns will enable enforcement of the laws
    against whichever candidate is elected President.            The
    Legislature finds and declares that compliance costs with this
    requirement will be trivial.” (Elec. Code, § 6881.)
    2. Legislative History
    The analyses prepared in connection with the
    Legislature’s consideration of Senate Bill No. 27 detailed the
    reasoning behind the measure.          A Senate floor analysis
    explained, “In 1973, the Providence Journal-Bulletin obtained
    and published data showing that President Richard Nixon had
    paid an astonishingly low amount in taxes in 1969 given his
    income for that year. After initially resisting calls for him to do
    so, Nixon eventually released his taxes and underwent an IRS
    audit. It turned out he had improperly claimed an exemption of
    $500,000 for papers he donated to the National Archives. [¶]
    Ever since this incident, it has been customary — though never
    required by law — for U.S. Presidential candidates to release
    their tax returns. Prior to 2016, only one candidate, President
    Gerald Ford in 1976, did not do so. Ford released a summary of
    8
    PATTERSON v. PADILLA
    Opinion of the Court by Cantil-Sakauye, C. J.
    his return instead. [¶] During the 2016 campaign for U.S.
    President, Donald Trump broke with this longstanding tradition
    and refused to release his tax returns. Though prompted by
    Trump’s break with the customary practice, this bill is not
    retroactive and would only apply to future presidential
    candidates.” (Sen. Rules Com., Off. of Sen. Floor Analysis,
    Unfinished Business Analysis of Sen. Bill No. 27 (2019-2020
    Reg. Sess.) as amended June 27, 2019, pp. 4-5.)4
    Several of these analyses also considered constitutional
    issues that might be implicated by the tax return disclosure
    requirement.5 However, these assessments concentrated on
    4
    Other analyses of Senate Bill No. 27 prepared while the
    bill was under consideration by the Legislature included similar
    background discussions. (Sen. 3d reading analysis of Sen. Bill
    No. 27 (2019-2020 Reg. Sess.) as amended June 27, 2019, p. 2;
    Sen. Rules Com., Off. of Sen. Floor Analyses, 3d reading analysis
    of Sen. Bill No. 27 (2019-2020 Reg. Sess.) as amended Apr. 10,
    2019, pp. 4-7; Assem. Com. on Appropriations, Analysis of Sen.
    Bill No. 27 (2019-2020 Reg. Sess.) as amended May 29, 2019,
    p. 2; Assem. Com. on Elections and Redistricting, Analysis of
    Sen. Bill No. 27 (2019-2020 Reg. Sess.) as amended May 29,
    2019, p. 4; Sen. Judiciary Com., Analysis of Sen. Bill No. 27
    (2019-2020 Reg. Sess.) as amended Mar. 11, 2019, pp. 4-5; Sen.
    Com. on Elections and Const. Amends., Analysis of Sen. Bill
    No. 27 (2019-2020 Reg. Sess.) as amended Mar. 11, 2019, p. 3.)
    5
    These analyses commonly expressed some uncertainty
    regarding whether courts would find the measure consistent
    with the United States Constitution. (E.g., Assem. Com. on
    Elections and Redistricting, Analysis of Sen. Bill No. 27 (2019-
    2020 Reg. Sess.) as amended May 29, 2019, pp. 4-6; Sen.
    Judiciary Com., Analysis of Sen. Bill No. 27 (2019-2020 Reg.
    Sess.) as amended Mar. 11, 2019, pp. 5-14; Sen. Com. on
    Elections and Const. Amends., Analysis of Sen. Bill No. 27
    (2019-2020 Reg. Sess.) as amended Mar. 11, 2019, pp. 3-4.)
    9
    PATTERSON v. PADILLA
    Opinion of the Court by Cantil-Sakauye, C. J.
    whether the disclosure requirement comported with the federal
    Constitution. The only analysis of Senate Bill No. 27 that
    mentioned the California Constitution was prepared for the
    Senate Judiciary Committee, and this evaluation discussed only
    the right to privacy conferred by the state charter (Cal. Const.,
    art. I, § 1) — not article II, section 5(c). (Sen. Judiciary Com.,
    Analysis of Sen. Bill No. 27, supra, p. 12, fn. 15.)6
    The analysis prepared for the Senate Judiciary Committee
    recognized that Senate Bill No. 149 (2017-2018 Reg. Sess.), a
    similar proposal that also would have conditioned access to the
    presidential primary ballot on a candidate’s disclosure of federal
    income tax returns, had been vetoed in 2017 by then-Governor
    Jerry Brown. The analysis recited a series of rhetorical
    questions Brown had posed in his veto message: “ ‘Today we
    require tax returns, but what would be next? Five years of
    health records? A certified birth certificate? High school report
    cards? And will these requirements vary depending on which
    political party is in power? A qualified candidate’s ability to
    appear on the ballot is fundamental to our democratic system.
    For that reason, I hesitate to start down a road that well might
    6
    A Senate Judiciary Committee analysis of the earlier
    Senate Bill No. 149 (2017-2018 Reg. Sess.) discussed how that
    measure had been amended while under consideration by the
    Legislature to avoid a potential conflict with article II, section 5,
    subdivision (d) of the state Constitution, which concerns the
    inclusion of candidates on the general election ballot. (Sen.
    Judiciary Com., Analysis of Sen. Bill No. 149 (2017-2018 Reg.
    Sess.) as amended Mar. 20, 2017, p. 11 [concluding the
    amendment “appears to eliminate the state constitutional
    concern”].) But that analysis did not recognize, much less
    address, the separate state constitutional issue presented by
    article II, section 5(c).
    10
    PATTERSON v. PADILLA
    Opinion of the Court by Cantil-Sakauye, C. J.
    lead to an ever escalating set of differing state requirements for
    presidential candidates.’ ” (Sen. Judiciary Com., Analysis of
    Sen. Bill No. 27, supra, at p. 14.) The committee analysis
    acknowledged that “[t]here is, in fact, some precedent for this
    [that is, conditioning ballot access upon some disclosure by a
    presidential candidate]. In 2011, for example, the Arizona
    legislature passed a bill that would have required presidential
    candidates to submit a birth certificate in order to appear on the
    state’s election ballot. The bill was vetoed by Governor Jan
    Brewer. According to a senior fellow with the National
    Conference of State Legislatures, 14 other states considered
    similar legislation.” (Ibid.) But, the analysis continued, “In
    response to this line of concern, the authors assert their belief
    that democratically elected legislatures are equipped to make
    reasoned assessments about what information is sufficiently
    important to their constituents to warrant a disclosure
    requirement and what information is not. If legislators go too
    far in demanding disclosures of presidential candidates, their
    fully informed constituents can always elect other
    representatives who will retract the requirement.” (Id., at
    p. 15.)
    B. Senate Bill No. 505
    The Governor signed a separate measure, Senate Bill
    No. 505, into law on the same day he signed the Act. Senate Bill
    No. 505 codified several criteria to be applied by the Secretary
    of State in determining who is to be placed on the appropriate
    presidential primary ballot as (i) a “recognized candidate[]
    throughout the nation or throughout California for the office of
    President of the United States” under article II, section 5(c), or
    (ii) a “generally advocated for or recognized” candidate for that
    office, in the phrasing of statutes that prescribe rules for the
    11
    PATTERSON v. PADILLA
    Opinion of the Court by Cantil-Sakauye, C. J.
    presidential primaries of specific political parties. (Elec. Code,
    §§ 6041, 6340, subd. (a), 6520, subd. (a), 6720, 6851.)
    Prior to the enactment of Senate Bill No. 505, the only
    elaboration within the Elections Code of what it means to be a
    “recognized” candidate for president appeared in the
    aforementioned statutes, each specifically tailored to an
    individual party that has qualified to participate in the state
    primary election. (See Elec. Code, § 5100 [setting forth the
    criteria for party qualification for the primary election].) The
    earliest precursors of the current laws to this effect were enacted
    in the 1970s, shortly after Proposition 4 was approved by the
    voters. (See Elec. Code, former § 6010, added by Stats. 1975,
    ch. 1048, § 2, p. 2468; Elec. Code, former § 6210, added by Stats.
    1975, ch. 1056, § 3, p. 2509; Elec. Code, former § 6110, added by
    Stats. 1975, ch. 1060, § 3, p. 2569; Elec. Code, former § 6310,
    added by Stats. 1974, ch. 1184, § 2, p. 2537.)
    The terms of the current statutes vary somewhat from
    party to party. They presently provide that a candidate for
    president is to be placed on the appropriate presidential primary
    ballot when the Secretary of State finds the person to be, with
    regard to the Democratic Party, “generally advocated for or
    recognized throughout the United States or California as
    actively seeking the nomination of the Democratic Party for
    President of the United States,” with the Secretary of State to
    “include as criteria for selecting [such] candidates the fact of
    qualifying for funding under the Federal Elections Campaign
    Act of 1974, as amended” (Elec. Code, § 6041); with regard to the
    Republican Party, “generally advocated for or recognized
    throughout the United States or California as a candidate for
    the nomination of the Republican Party for President of the
    United States” (id., § 6340, subd. (a)); with regard to the
    12
    PATTERSON v. PADILLA
    Opinion of the Court by Cantil-Sakauye, C. J.
    American Independent Party, “generally advocated for or
    recognized in the news media throughout the United States or
    California as actively seeking the nomination of the American
    Independent Party for President of the United States” (id.,
    § 6520, subd. (a)); with regard to the Peace and Freedom Party,
    “generally advocated for or recognized throughout the United
    States or California as actively seeking the presidential
    nomination of the Peace and Freedom Party or the national
    party with which the Peace and Freedom Party is affiliated” (id.,
    § 6720); and, with regard to the Green Party, “generally
    advocated for or recognized throughout the United States or
    California as actively seeking the presidential nomination of the
    Green Party or the national political party with which the Green
    Party is affiliated” (id., § 6851).
    The available historical materials indicate that prior to
    the approval of Senate Bill No. 505, the Secretary of State relied
    on various criteria or factors in identifying “recognized” or
    “generally advocated for or recognized” candidates for president.
    In 1976, then-Secretary of State March Fong Eu explained that
    in developing an initial list of “active presidential candidates for
    California,” she had “taken into consideration a number of
    factors, including the fact that the persons are announced
    candidates, appear to be actively campaigning, have qualified
    for matching federal funds under the 1974 amendments to the

    other states’ primary ballots.” (Sect. of State, News Release,

    articulated by Eu’s successors as Secretary of State.7
    Senate Bill No. 505 added sections 6000.1 and 6000.2 to
    the Elections Code. Section 6000.1 sets forth criteria for being
    identified as a “generally advocated for or recognized” or
    “recognized” candidate for president. These criteria overlap to
    some extent with the factors applied by former Secretary of
    State Eu. (Elec. Code, § 6000.1, subds. (a)-(e).) Section 6000.2
    further provides that on or before the 98th day prior to the
    presidential primary election, a candidate for president is to file
    a form with the Secretary of State, together with any supporting
    documentation, establishing that the candidate is a “generally
    advocated for or recognized” candidate under the standard set
    forth in section 6000.1. (Id., § 6000.2, subds. (a), (b).)

    return disclosure requirement for presidential candidates that
    was adopted through Senate Bill No. 27. Our analysis here

    For the 2008 California presidential primary, for example,
    then-Secretary of State Debra Bowen stated that the
    determination of whether a person would appear on the primary
    ballot as a candidate for president “is based on a number of
    factors, including whether a candidate: [¶] . . . [p]articipates in
    candidate debates; . . . [a]ctively campaigns in California; . . .
    [a]ppears in public opinion polls; and/or [¶] . . . [q]ualifies for
    federal campaign matching funds. [¶] Additionally, Secretary
    Bowen asked each of the six California political parties to
    submit a list of candidates whom they recognize as seeking their
    party’s nomination.” (Sect. of State, News Release, Secretary of
    State Releases List of Presidential Candidates for February

    therefore need not, and does not, address the constitutionality
    of Elections Code sections 6000.1 and 6000.2.
    C. Procedural History
    On August 6, 2019, petitioners filed an emergency petition
    for writ of mandate or other extraordinary or immediate relief
    with this court. The petition identifies Patterson as “an
    individual California voter, a registered Republican, and
    current Chairperson of the Petitioner California Republican
    Party.” She alleges that she “desires to participate as a voter
    and to lead her state political party by supporting the inclusion
    of all qualified Republican Presidential candidates in the open
    Presidential primary.” The petition for writ of mandate also
    alleges that Patterson “fears that a large number of Republican
    voters will be suppressed and discouraged from voting at the
    primary election as a result of the Secretary of State’s
    implementation of [Senate Bill No. 27], if qualified Republican
    candidates are excluded from the Republican Party’s
    Presidential primary ballot.” The California Republican Party
    is identified as “the ballot-qualified statewide political party
    representing more than 4.7 million registered Republican
    voters,” and the petition states that the party and “its adherents
    participate in the partisan Presidential primary,” among other
    electoral contests.
    Petitioners assert that the Act’s income tax return
    disclosure requirement “plainly conflicts with the constitutional
    provision of [a]rticle II, section 5(c) guaranteeing an open
    Presidential primary.” They request a writ of mandate that
    would prohibit respondent “from enforcing Elections Code
    sections 6883 and 6884 . . . as fundamentally inconsistent and
    in conflict with [a]rticle II, section 5(c).” Petitioners seek this
    15
    PATTERSON v. PADILLA
    Opinion of the Court by Cantil-Sakauye, C. J.
    relief on an emergency basis because the Act’s deadline for
    submission of tax returns to the Secretary of State is November
    26, 2019 (98 days before the March 3, 2020 primary election; see
    Elec. Code, § 6883, subd. (a)), and “the sitting President of the
    United States who has announced that he is a Presidential
    candidate for the 2020 election has in the past declined to
    release his federal tax returns.”
    After requesting and receiving preliminary opposition
    from respondent, we ordered him to show cause why a writ of
    mandate should not issue. To ensure the timely disposition of
    the cause, we directed expedited briefing in which the parties
    would address, among other subjects, the history of Proposition
    4 and related legislation, and any guidelines, including internal
    measures and protocols, that the Secretary of State has used to
    determine who are “recognized candidates throughout the
    nation or throughout California for the office of President of the
    United States.”
    II. DISCUSSION
    Petitioners    and    respondent      advance    divergent
    constructions of article II, section 5(c), which carry different
    implications for the constitutionality of Elections Code sections
    6883 and 6884.
    As has been explained, petitioners regard article II,
    section 5(c) as specifying a rule of inclusivity for presidential
    primary contests that cannot be infringed through legislation
    such as the Act. According to petitioners, article II, section 5(c)
    requires all individuals who are found to be “recognized
    candidates throughout the nation or throughout California for
    the office of President of the United States” to be named on the
    appropriate primary ballot, unless an affidavit of noncandidacy
    16
    PATTERSON v. PADILLA
    Opinion of the Court by Cantil-Sakauye, C. J.
    is filed. And, their argument continues, even if one assumes
    that the Legislature may play a role in defining what it means
    to be “recognized . . . throughout the nation or throughout
    California” as a candidate “for the office of President of the
    United States,” noncompliance with the Act’s disclosure
    provisions cannot provide a basis for excluding a candidate from
    the ballot because a candidate’s failure to file income tax returns
    with the Secretary of State is not a reasonable measure of
    whether a candidate is so recognized.
    Respondent interprets article II, section 5(c) differently.
    He emphasizes the Legislature’s expansive authority to adopt
    legislation concerning primary elections — as recognized both
    before and after the approval of Proposition 4 (e.g., Libertarian
    Party v. Eu (1980) 
    28 Cal. 3d 535
    , 540; Communist Party v. Peek
    (1942) 
    20 Cal. 2d 536
    , 544) — and argues that in amending the
    state Constitution to add the relevant text now found in article
    II, section 5(c), voters “did not vitiate the Legislature’s ability to
    regulate [primary] elections and pass laws that, for instance,
    limit candidates to those within recognized parties, require
    forms to be filed, or require information to be disclosed to better
    educate California’s voters.” Respondent thus reads article II,
    section 5(c) as recognizing, rather than constraining, the
    Legislature’s power to prescribe rules governing presidential
    primary elections. Pursuant to this authority, the Legislature
    may, in respondent’s words, “enact laws regulating the process
    by which particular candidates appear on a party’s primary
    ballot, even if they are nationally recognized.” (Italics added.)
    From this perspective, the Act’s income tax return disclosure
    requirement for presidential candidates, including its directive
    to the Secretary of State not to place the names of noncompliant
    17
    PATTERSON v. PADILLA
    Opinion of the Court by Cantil-Sakauye, C. J.
    candidates on the primary ballot, represents an appropriate
    exercise of the Legislature’s authority.
    To summarize the analysis that follows, we agree with
    petitioners that whatever authority the Legislature may have in
    defining how presidential primaries are to occur in this state,
    the challenged sections of the Act exceed such authority and are
    unenforceable. These provisions purport to exclude from the
    California presidential primary ballot any candidate who does
    not comply with the income tax return disclosure requirement
    — even someone who is incontestably “recognized . . .
    throughout the nation or throughout California” as a candidate
    “for the office of President of the United States” under any
    reasonable construction of that phrasing. But as explained
    below, article II, section 5(c) is most naturally read as conveying
    a rule of inclusivity for presidential primary elections that the
    Legislature cannot contravene.          This reading is strongly
    supported by the history of the constitutional text that now
    appears in article II, section 5(c). This history establishes
    beyond fair dispute that this language was adopted to ensure
    that the ballots for parties participating in the presidential
    primary election would include all persons within said parties
    deemed to be “recognized candidates throughout the nation or
    throughout California for the office of President of the United
    States,” except for those candidates who filed affidavits of
    noncandidacy, so that voters in the primary election would have
    a direct opportunity to vote for or against these candidates.
    Because the relevant provisions of the Act condition a
    presidential candidate’s placement on the primary ballot on
    compliance with an additional requirement that is concededly
    not a reasonable measure of whether the candidate is
    “recognized” as such throughout the nation or California, it
    18
    PATTERSON v. PADILLA
    Opinion of the Court by Cantil-Sakauye, C. J.
    conflicts with the rule specified by article II, section 5(c), and is
    for that reason invalid. (People v. Navarro (1972) 
    7 Cal. 3d 248
    ,
    260 [when a statute conflicts with the Constitution, “the latter
    must prevail”].)8
    A. Article II, Section 5(c)
    Our interpretive task begins with the language of article
    II, section 5(c). (See Kennedy Wholesale, Inc. v. State Bd. of
    Equalization (1991) 
    53 Cal. 3d 245
    , 249-250; cf. Santos v. Brown
    (2015) 
    238 Cal. App. 4th 398
    , 409.) To reiterate, this provision
    states as follows: “The Legislature shall provide for partisan
    elections for presidential candidates, and political party and
    party central committees, including an open presidential
    primary whereby the candidates on the ballot are those found
    by the Secretary of State to be recognized candidates throughout
    the nation or throughout California for the office of President of
    the United States, and those whose names are placed on the
    ballot by petition, but excluding any candidate who has
    withdrawn by filing an affidavit of noncandidacy.”
    Respondent has not sought to justify the Act’s income tax
    disclosure requirement on the ground that it represents a
    reasonable measure of whether someone is “recognized . . .
    throughout the nation or throughout California” as a candidate
    “for the office of President of the United States.” At oral
    argument, counsel for respondent conceded that whether a
    8
    Because the issue is not before us, we need not decide here
    whether the tax return disclosure requirement can properly be
    applied to candidates for president who would qualify for the
    primary election ballot through the petition process articulated
    in article II, section 5(c).
    19
    PATTERSON v. PADILLA
    Opinion of the Court by Cantil-Sakauye, C. J.
    candidate for president has filed recent tax returns with the
    Secretary of State is not indicative of whether the candidate is
    so “recognized.”9
    9
    Even apart from this concession, under any reasonable
    interpretation of the “recognized” language within article II,
    section 5(c), a candidate’s failure to disclose tax returns to the
    Secretary of State would not establish that the candidate is not
    “recognized . . . throughout the nation or throughout California”
    as a candidate “for the office of President of the United States.”
    The word “recognized” is susceptible to somewhat
    different meanings. (Compare, e.g., Black’s Law Dict. (4th ed.
    1968) p. 1436, col. 2 [defining “recognized” as “[a]ctual and
    publicly known”] with Random House Dict. of the English
    Language (1973) p. 1199, col. 3 [defining “recognize” as, among
    other things, “to acknowledge or treat as valid”].) The repeated
    use of the word “throughout” within article II, section 5(c)
    suggests that the “recognized” language is concerned (although
    perhaps not exclusively) with a candidacy’s prominence or
    pervasiveness. (See Webster’s 3d New Internat. Dict. (1971) p.
    2385, col. 1 [defining “throughout” as “in . . . every part of”].) If
    this meaning applies, it seems plain that whether a candidate
    has disclosed tax returns to the Secretary of State cannot, by
    itself, be determinative of whether the candidate is “recognized.”
    Such disclosure has, at most, a highly attenuated relationship
    to public awareness of a candidacy throughout the nation or
    California — or, for that matter, to whether someone is an
    “[a]ctual” candidate for the presidency. (Black’s Law Dict., at
    p. 1436, col. 2.)
    The disjunctive “throughout the nation or throughout
    California” language in article II, section 5(c) also suggests that
    nondisclosure of tax returns under the Act could not supply a
    basis for keeping a presidential candidate off the primary ballot
    even if the “recognized” phrasing were to be construed as being
    to some extent concerned with a candidacy’s validity. For even
    in that case, a failure to comply with the Act’s tax return
    disclosure requirement would establish only that someone is not
    “recognized,” i.e., not regarded as valid, as a presidential
    20
    PATTERSON v. PADILLA
    Opinion of the Court by Cantil-Sakauye, C. J.
    Instead, as noted, respondent posits that the legislative
    authority envisioned by article II, section 5(c)’s directive that
    “[t]he Legislature shall provide for . . . an open presidential
    primary” includes the power to adopt additional prerequisites
    for appearing on the primary ballot that even a “recognized”
    candidate for president must satisfy.10
    candidate in or by California. It would not mean that the
    candidate is not “recognized . . . throughout the nation,” because
    a failure to satisfy this requirement would not make a candidacy
    invalid throughout the nation.
    10
    Respondent’s interpretation emphasizes language within
    article II, section 5(c) that acknowledges the Legislature’s broad
    authority to provide for primary elections, a power that was
    already well-established at the time of the 1972 primary election
    at which Proposition 4 passed.
    When the electorate approved Proposition 4, the state
    Constitution specifically described the Legislature’s authority
    over primary elections as follows: “The Legislature shall have
    the power to enact laws relative to the election of delegates to
    conventions of political parties; and the Legislature shall enact
    laws providing for the direct nomination of candidates for public
    office, by electors, political parties, or organizations of electors
    without conventions, at elections to be known and designated as
    primary elections; also to determine the tests and conditions
    upon which electors, political parties, or organizations of
    electors may participate in any such primary election. . . .” (Cal.
    Const., art. II, former § 2.5.)
    “The purpose of this [provision] was to give the Legislature
    a free hand in dealing with the evils which had formerly been
    prevalent in primary elections, even to the extent of excluding
    parties and individuals from participation therein.”
    (Communist Party v. Peek, supra, 20 Cal.2d at p. 544.) This
    authority included the power to “determine the tests and
    conditions upon which participation in a primary election may
    be had either by electors as voters thereat or by electors as
    candidates thereunder.” (Socialist Party v. Uhl (1909) 
    155 Cal. 21
    PATTERSON v. PADILLA
    Opinion of the Court by Cantil-Sakauye, C. J.
    But article II, section 5(c) is more readily construed as
    both recognizing the Legislature’s authority to provide for
    primary elections and imposing a specific constraint on this
    power. This provision begins, “The Legislature shall provide for
    partisan elections for presidential candidates, and political
    party and party central committees” — language that, as
    respondent emphasizes, conveys the Legislature’s responsibility
    to develop a primary election scheme. Immediately thereafter,
    however, the provision continues, “including an open
    presidential primary whereby the candidates on the ballot are
    those found by the Secretary of State to be recognized
    candidates throughout the nation or throughout California for
    the office of President of the United States . . . .” (Italics added.)
    This language appears to convey an absolute requirement of a
    presidential primary ballot for each qualifying party that
    includes all persons seeking the party’s presidential nomination
    who have been found to be “recognized candidates throughout
    the nation or throughout California for the office of President of
    the United States.” In other words, the presidential primary
    that the Legislature must “provide for” is one in which all
    persons deemed to be “recognized candidates throughout the
    nation or throughout California for the office of President of the
    776, 792.) In an early decision by this court construing article
    II, section 2½ of the Constitution (later renumbered section 2.5),
    we observed that “[t]he right is thus conferred to prescribe any
    reasonable test and it is the duty of the [L]egislature to prescribe
    one.” (Socialist Party, at p. 792.)
    Article II, section 2.5 of the California Constitution was
    repealed upon the approval of Proposition 7 by the electorate at
    the November 1972 general election. Today, the various
    subdivisions of article II, section 5 of the Constitution address
    how primary elections are to occur.
    22
    PATTERSON v. PADILLA
    Opinion of the Court by Cantil-Sakauye, C. J.
    United States” are to appear on the appropriate primary ballot
    (along with presidential candidates who qualify for the ballot
    through the petition process), except for those candidates who
    file affidavits of noncandidacy pursuant to the final clause of
    article II, section 5(c).     Under this interpretation, the
    Constitution prohibits the Legislature from adopting disclosure
    requirements that a presidential candidate identified as so
    recognized also must satisfy to appear on the primary ballot.
    The text of article II, section 5(c), therefore, does not
    support respondent’s view that the Legislature may adopt an
    income tax return disclosure requirement that could exclude
    “recognized candidates throughout the nation or throughout
    California for the office of President of the United States” from
    a presidential primary ballot. We now turn to the history of this
    provision, which removes any doubt regarding the intent behind
    article II, section 5(c).
    B. Historical Background
    As approved by the electorate in 1972, Proposition 4
    changed how candidates for the office of President of the United
    States qualify to be named on a primary ballot in this state.
    Before this measure came into effect, candidates for president
    had to take affirmative steps to enter the California primary.
    Advocates for ballot reform perceived that this system
    frustrated voters’ ability to choose among a comprehensive
    array of candidates at presidential primary elections and
    diminished the state’s influence in the national presidential
    nomination process. Proposition 4 responded to these concerns
    by requiring that all nationally or California-recognized
    candidates be included on the ballot, unless a person deemed to
    be such a candidate submits an affidavit of noncandidacy.
    23
    PATTERSON v. PADILLA
    Opinion of the Court by Cantil-Sakauye, C. J.
    Because of this change to the presidential primary ballot,
    California voters now have the ability to express their
    preferences among candidates for their parties’ presidential
    nominations more directly and meaningfully than had
    previously been the case.
    1. The Prior “Opt-in” Approach to the Primary Ballot
    The statutory scheme for primary elections that was in
    place in this state prior to Proposition 4 did not guarantee that
    even the most prominent presidential candidates would appear
    on a primary ballot. To appear on the ballot, a person had to
    submit to the Secretary of State written permission for delegate
    candidates to pledge themselves to that person. (Elec. Code,
    former § 6055.) The candidate for president would appear on
    the primary ballot if these candidates for delegates received
    enough signatures on nomination papers. (Id., former §§ 6057,
    6058, 6080-6088, 6804, 10261; see also Review of Selected 1975
    California Legislation (1976) 7 Pacific L.J. 237, 439 [“Prior to
    1974, presidential primary ballots for the major political parties
    in California listed only those candidates who petitioned to
    appear on the election ballot”].)
    Under this regime, some noteworthy candidates for
    president avoided the California primary. In 1960, John F.
    Kennedy, who was elected president that November, was not
    among the candidates listed on the ballot for the Democratic
    Party primary contest. Instead, the only persons named on that
    ballot were then-Governor Pat Brown and activist George
    McLain. (Rarick, California Rising: The Life and Times of Pat
    Brown (2005) p. 182 (Rarick).) Similarly, in 1968 the eventual
    Republican Party nominee, Richard Nixon, did not appear on his
    party’s California primary ballot. The only name printed on
    24
    PATTERSON v. PADILLA
    Opinion of the Court by Cantil-Sakauye, C. J.
    that ballot was that of Ronald Reagan, the governor at that time.
    (Owens et al., California Politics and Parties (1970) p. 88
    (Owens).) Hubert Humphrey, Nixon’s rival as the Democratic
    Party nominee that autumn, did not directly participate in the
    1968 California presidential primary, either. The Democratic
    Party primary ballot that year named only Senators Eugene
    McCarthy and Robert Kennedy, and then-Attorney General
    Thomas Lynch. (Id., at p. 84; Ross & Stone, California’s Political
    Processes (1973) p. 37 (Ross & Stone).)
    The candidacies of Brown in 1960 and Reagan in 1968
    involved “favorite son” campaigns for president. “As a favorite
    son, a governor or senator entered his state’s primary . . . even
    though he had no real hope of becoming president. Assuming
    that he won, the state’s delegates would go to the convention
    pledged to him. On the convention floor favorite sons had two
    alternative strategies, which often overlapped. Sometimes they
    dreamed of snatching the nomination if none of the serious
    candidates could find a majority and the convention deadlocked.
    If not — and this was the more common outcome — they used
    their delegations as bargaining chips in dealing with potential
    nominees. Once the favorite son withdrew, the delegates were
    not legally obligated to follow his lead in voting for another
    candidate, but often, through a combination of intimidation or
    affection, a favorite son could lead his followers to one camp or
    another.” (Rarick, supra, at p. 182; see also Davis, Presidential
    Primaries (2d ed. 1980) pp. 189-194 (Davis).)
    Although the presence of a “favorite son” in a California
    presidential primary did not create a legal impediment to other
    candidates entering the fray, the presence of such a candidate
    could discourage national politicians from contesting the race.
    (Owens, supra, at pp. 87-88.) As one commentator observed in
    25
    PATTERSON v. PADILLA
    Opinion of the Court by Cantil-Sakauye, C. J.
    1970, “Recent experience suggests that despite all the reasons
    for entering the California [primary] race, some active
    presidential aspirants decline to enter.” (Id., at p. 87.) With a
    favorite son in the mix, “National candidates, out of courtesy,
    refrain[ed] from creating delegations in their own names.” (Ross
    & Stone, supra, at p. 37.) An out-of-state candidate wading into
    a primary already populated by a favorite son not only invited
    an embarrassing loss to a more locally well-known contestant;
    he or she also risked “alienating party leadership in the state or
    damaging party unity, perhaps beyond repair, just prior to a
    general election campaign.” (Owens, at p. 88). Meanwhile, the
    fact that a favorite son candidate was unlikely to secure a
    party’s nomination for president “mean[t] that the voter voting
    for a favorite son in reality [did] not know what national
    candidate [would] be supported” by the delegates, who were
    initially pledged to the local candidate but became free to vote
    for other candidates once the favorite son withdrew from the
    race. (Ross & Stone, at p. 37; see Rarick, supra, at p. 182.)
    Although favorite son candidacies were a longtime feature
    of the presidential primary landscape (see Davis, supra, at
    p. 90), as the 1960s progressed criticisms of these candidacies
    mounted in California. Critics attacked favorite son candidacies
    as hindering the ability of California voters to effectively express
    their preferences at the ballot box, and as limiting this state’s
    relevance in the national presidential primary process. In an
    editorial following the failed Reagan candidacy in 1968, the Los
    Angeles Times newspaper opined, “Governor Reagan froze out
    all other Republican contenders by heading up a ‘favorite son’
    delegation . . . [¶] The favorite son device is not new, here or
    elsewhere. It has been used in the past by both Democrats and
    Republicans. Yet the temper of the times is such that it should
    26
    PATTERSON v. PADILLA
    Opinion of the Court by Cantil-Sakauye, C. J.
    now be discarded in favor of giving the voters a more direct and
    meaningful voice in the selection of their nominees.” (Toward
    Better Elections, L.A. Times (Aug. 28, 1968) p. A4; see also
    Governor’s Veto of Primary Bill, S.F. Chronicle (Sept. 3, 1968)
    p. 38 [editorial]; Open Primary More Vital Than Ever, San Jose
    Mercury News (Feb. 27, 1969) p. 2 [editorial].) Communicating
    a similar view among the electorate, one poll conducted in 1968
    reported that 77 percent of those surveyed would have preferred
    a choice among candidates in the 1968 Republican Party
    primary, instead of only a delegate slate pledged to Governor
    Reagan. (Field Research Corp., The Field Poll, California Poll
    68-03 (May 15-18, 1968).)
    2. Earlier Attempts To Enact Responsive Statutes
    The constitutional amendment adopted through
    Proposition 4 was approved by the voters in 1972 after repeated
    failures to enact statutes that would have made similar changes
    to the presidential primary ballot.
    In 1965, 1967, 1968, 1969, and 1971, bills were introduced
    in the Legislature that, had they become law, would have
    replaced the existing “opt-in” scheme for presidential primary
    candidates with a more inclusive approach.11 These proposals
    drew from an Oregon law (1961 Or. Laws, ch. 170, § 1, p. 181)
    that had made such a change to the presidential primary system
    in that state.       (See Assem. Com. on Elections and
    Reapportionment, Analysis of Sen. Bill No. 145 (1968 Reg. Sess.)
    p. 1 [“Senate Bill 145 is an act to create for California a

    The bill introduced in 1965 applied only to the presidential
    primary of a party for which there were fewer than 3.5 million
    registered voters in the state. (Assem. Bill No. 1414 (1965 Reg.
    Sess.), supra, § 2 [proposed Elec. Code, § 6300].)

    Oregon”].)
    Each of the ballot reform measures introduced in the
    Legislature provided that the Secretary of State “shall place the
    name” of a candidate for president upon the presidential
    primary ballot when that state officer “shall have determined in
    his sole discretion that such a candidate” (or, in some versions
    of the proposed legislation, “such candidate’s candidacy”) “is
    generally advocated for or recognized in” the “news media
    throughout the United States.”12 (Sen. Bill. No. 3 (1971 Reg.
    Sess.) as introduced Jan. 4, 1971, § 2 [proposed Elec. Code,
    § 6052]; Sen. Bill. No. 3 (1969 Reg. Sess.) as introduced Jan. 7,
    1969, § 2 [proposed Elec. Code, § 6052]; Sen. Bill No. 145 (1968
    Reg. Sess.) as introduced Jan. 30, 1968, § 2 [proposed Elec. Code,
    § 6052]; Sen. Bill No. 586 (1967 Reg. Sess.) as introduced Mar.
    14, 1967, § 2 [proposed Elec. Code, § 6051]; Assem. Bill No. 1414
    (1965 Reg. Sess.) as introduced February 24, 1965, § 2 [proposed
    Elec. Code, § 6351].)13 All of these bills would have allowed a
    candidate to avoid being placed on the ballot by executing an
    12
    The proposed legislation introduced in 1971 would have
    added “or California” after “United States.” (Sen. Bill. No. 3
    (1971 Reg. Sess.), supra, § 2 [proposed Elec. Code, § 6052].)
    13
    Each of these measures also made provision for the
    inclusion of additional candidates on the primary ballot when
    petitions on behalf of their candidacy had collected a sufficient
    number of signatures. (Sen. Bill No. 3 (1971 Reg. Sess.), supra,
    § 2 [proposed Elec. Code, §§ 6053-6059]; Sen. Bill No. 3 (1969
    Reg. Sess.), supra, § 2 [proposed Elec. Code, §§ 6053-6059]; Sen.
    Bill No. 145 (1968 Reg. Sess.), supra, § 2 [proposed Elec. Code,
    §§ 6053-6056]; Sen. Bill No. 586 (1967 Reg. Sess.), supra, § 2
    [proposed Elec. Code, § 6051]; Assem. Bill No. 1414 (1965 Reg.
    Sess.), supra, § 2 [proposed Elec. Code, § 6351].)

    become, a candidate for president in the forthcoming election.14
    The bills that were introduced in 1965 and 1967 died
    without a floor vote in either chamber of the Legislature. (Cal.
    Legis., Final Calendar of Legislative Business (1965 Reg. Sess.)
    p. 458; Sen. Final Hist. (1967 Reg. Sess.) p. 171.) The Assembly
    and the Senate passed the 1968, 1969, and 1971 bills,15 but in
    each instance the legislation was vetoed by then-Governor
    Reagan. In his veto message rejecting Senate Bill No. 145 (1968
    Reg. Sess.), Reagan wrote that this measure “adds nothing to
    14
    As with the other proposed statutory reforms to the
    primary ballot discussed in the text, the bills would have
    incorporated this requirement into the Elections Code. (Sen.
    Bill No. 3 (1971 Reg. Sess.) § 2 [proposed Elec. Code, § 6061];
    Sen. Bill No. 3 (1969 Reg. Sess.) § 2 [proposed Elec. Code,
    § 6061]; Sen. Bill No. 145 (1968 Reg. Sess.) § 2 [proposed Elec.
    Code, § 6058]; Sen. Bill No. 586 (1967 Reg. Sess.) § 2 [proposed
    Elec. Code, §§ 6051, 6052]; Assem. Bill No. 1414 (1965 Reg.
    Sess.) § 2 [proposed Elec. Code, §§ 6351, 6352].)
    15
    The Assembly and Senate passed versions of the 1968,
    1969, and 1971 bills that had been amended in the legislative
    process. These amendments are generally immaterial to the
    issues before the court, with the possible exception of one change
    made to the 1971 measure, Senate Bill No. 3 (1971 Reg. Sess.).
    That bill was amended in the Assembly to add the italicized
    language that appears below: “The Secretary of State shall
    place the name of a candidate upon the presidential primary
    ballot when the Secretary of State shall have determined in his
    sole discretion that such a candidate is generally advocated for
    or recognized in the news media throughout the United States
    or California as actively seeking his party’s nomination for
    President of the United States and that such a candidate has
    formed a delegation in conformity with the applicable provisions
    of this division.” (Sen. Bill. No. 3 (1971 Reg. Sess.) as amended
    Nov. 24, 1971, § 1, italics added [proposed Elec. Code, § 6066].)

    Opinion of the Court by Cantil-Sakauye, C. J.
    the democratic process. It is, in fact, an infringement on the
    rights of certain individuals. It limits the people’s responsibility
    by placing the responsibility for putting names on the California
    presidential ballot on the shoulders of one man. This is
    considerably less desirable than California’s open primary
    method which requires a significant number of persons to show
    an interest in a man’s candidacy before his name can be placed
    on the ballot.” (Governor’s Veto Message to Sen. on Sen. Bill
    No. 145 (Aug. 22, 1968) 1969 Sen. J. (1968 Reg. Sess.) p. 4959.)
    Reagan issued similar veto messages in rejecting Senate Bill No.
    3 (1969 Reg. Sess.), the ballot reform measure approved by the
    Legislature in its 1969 Regular Session (Governor’s Veto
    Message to Sen. on Sen. Bill No. 3 (Sept. 4, 1969) 1969 Sen. J.
    (1969 Reg. Sess.) p. 5695 (hereafter 1969 Veto Message)), and
    the Senate Bill No. 3 that was approved by the Legislature in its
    1971 Regular Session (Governor’s Veto Message to Sen. on Sen.
    Bill No. 3 (Dec. 30, 1971) 1972 Sen. J. (1972 Reg. Sess.) p. 9939).
    In vetoing the 1969 measure, Reagan added, “If a candidate is,
    indeed, ‘generally recognized’ as a serious presidential
    contender, his supporters should have no difficulty in gathering
    sufficient signatures to place his name on the California ballot.”
    (1969 Veto Message, supra, at p. 5696.)
    3. The Electorate’s Approval of Proposition 4 as a
    Constitutional Amendment, Creating an “Open
    Presidential Primary”
    In 1970, after several attempts at making changes to the
    presidential primary election by statute had failed, a
    constitutional amendment with a similar goal (Sen. Const.
    Amend. No. 3 (1970 Reg. Sess.)) was introduced in the
    Legislature. This proposal would have added section 7 to article
    II of the state Constitution, with the text, “The Legislature shall
    30
    PATTERSON v. PADILLA
    Opinion of the Court by Cantil-Sakauye, C. J.
    provide for an open presidential primary whereby the
    candidates on the ballot are those found by the Secretary of
    State to be recognized candidates throughout the nation or
    throughout California for the office of President of the United
    States, and those whose names are placed on the ballot by
    petition, but excluding any candidate who has withdrawn by
    filing an affidavit that he is not a candidate.” (Sen. Const.
    Amend. No. 3 (1970 Reg. Sess.).) The Senate approved this
    proposed amendment, but it was tabled in the Assembly and
    never came before the electorate for approval. (Cal. Legis., Final
    Calendar of Legislative Business (1970 Reg. Sess.) p. 362.)
    The next year, both chambers of the Legislature approved
    a similar proposal, Senate Constitutional Amendment No. 3
    (1971 Reg. Sess.). (Sen. Final Hist. (1971 Reg. Sess.) p. 501.)
    This measure represented an alternative method of
    accomplishing the goals of the aforementioned Senate Bill No. 3
    (1971 Reg. Sess.), in the event Governor Reagan vetoed the bill.
    (See letter from Sen. Alfred E. Alquist to Governor Ronald
    Reagan (Dec. 8, 1971) p. 1 [explaining that, should the Governor
    approve Sen. Bill No. 3 (1971 Reg. Sess.), the bill’s sponsor
    would “utilize the appropriate legislative provisions for the
    removal of [the proposed constitutional amendment] from the
    June, 1972, ballot”].) After Governor Reagan vetoed Senate Bill
    No. 3 (1971 Reg. Sess.), Senate Constitutional Amendment No.
    3 appeared on the ballot as Proposition 4 at the June 1972
    primary election, at which time it was approved by the voters.
    Proposition 4 added article II, section 8 to the state
    Constitution, providing, “The Legislature shall provide for an
    open presidential primary whereby the candidates on the ballot
    are those found by the Secretary of State to be recognized
    candidates throughout the nation or throughout California for
    31
    PATTERSON v. PADILLA
    Opinion of the Court by Cantil-Sakauye, C. J.
    the office of President of the United States, and those whose
    names are placed on the ballot by petition, but excluding any
    candidate who has withdrawn by filing an affidavit that he is
    not a candidate.” Subsequent amendments to the state
    Constitution have altered this phrasing somewhat and moved
    the pertinent text to article II, section 5(c), but have not made
    any changes fundamental to the issue before the court.16
    The analysis and arguments regarding Proposition 4 that
    appeared within the ballot materials before the voters at the
    1972 primary election provide substantial insight into the intent
    behind this measure. (See People v. Gonzales (2017) 2 Cal.5th
    858, 881 [describing ballot materials as “a useful source of
    ascertaining voter intent”]; Silicon Valley Taxpayers’ Assn., Inc.
    v. Santa Clara County Open Space Authority (2008) 
    44 Cal. 4th 431
    , 445.) These materials situate the amendment in the
    historical context summarized above (see Robert L. v. Superior
    Court (2003) 
    30 Cal. 4th 894
    , 904; Hi-Voltage Wire Works, Inc. v.
    City of San Jose (2000) 
    24 Cal. 4th 537
    , 542, 560) and manifest
    an intent, through the measure, to require all “recognized”
    candidates for president to be placed on the appropriate party’s
    primary ballot, in order to avoid the candidate participation
    problems associated with the then-existing primary process.
    16
    Most recently, Proposition 14, which the electorate
    adopted in 2010 to create a new “top-two candidates open
    primary election” procedure for state and congressional primary
    elections, redesignated the presidential primary provision as
    subdivision (c) of section 5, article II, and slightly revised the
    opening passage of that subdivision to indicate that partisan
    elections are to be retained for presidential candidates and
    political party and party central committees.
    32
    PATTERSON v. PADILLA
    Opinion of the Court by Cantil-Sakauye, C. J.
    Within the relevant ballot materials, the Legislative
    Counsel’s general analysis of the measure explained, “A ‘Yes’
    vote on this measure is a vote to require the placement on the
    presidential primary ballot of the names of all recognized
    candidates for president and all candidates qualified by virtue
    of nominating petitions, unless such a candidate withdraws. [¶]
    A ‘No’ vote is a vote to reject this requirement.” (Ballot Pamp.,
    Primary Elec. (June 6, 1972) general analysis of Prop. 4 by
    Legis. Counsel, p. 9, italics added (hereafter June 1972 Ballot
    Pamphlet).) The Legislative Counsel’s detailed analysis added,
    in relevant part, “This measure would add Section 8 to article II
    of the California Constitution and direct the Legislature to
    provide for an open presidential primary. It would require the
    Secretary of State to place upon the presidential primary ballot
    of the appropriate political party as its candidates for the office
    of President of the United States, the names of those persons
    who he determined to be either (a) recognized as candidates
    throughout the nation or (b) recognized as candidates
    throughout California.” (Id., detailed analysis of Prop 4. by
    Legis. Counsel, p. 10, italics added.)
    The arguments in favor of Proposition 4 within the official
    ballot pamphlet also described how the measure would function,
    and explained why it was being proposed. Proponents stated, in
    pertinent part, “This Constitutional Amendment is designed to
    give voters a meaningful voice in choosing their party’s
    presidential nominee. It requires the Legislature to provide for
    an open presidential primary in which the Secretary of State
    places on the ballot the names of recognized candidates for the
    office of President of the United States.” (June 1972 Ballot
    Pamp., supra, argument in favor of Prop. 4, p. 10.) The
    argument in favor of Proposition 4 later continued, “The present
    33
    PATTERSON v. PADILLA
    Opinion of the Court by Cantil-Sakauye, C. J.
    system of selecting presidential candidates often leaves the
    voter without a direct voice in the decision. The ‘favorite son’
    device has been used by Governors from both parties to prevent
    a contested primary, depriving the voters of a chance to vote for
    the candidate of his choice. [¶] In the last presidential primary
    election, California voters were denied the opportunity of voting
    for or against either of the men who eventually became the
    presidential nominees. [¶] Opponents claim an open primary
    would impair ‘party unity’ and would require costly election
    campaigns. But who wants ‘party unity’ at the expense of party
    members? And why shouldn’t the candidates campaign in
    California as well as in New Hampshire, Indiana, and Oregon?
    [¶] The open primary plan would make California the key state
    every presidential election. As the most populous state in the
    union, it should be. It is time the voters have a say in
    nominating their party’s candidate for the highest office in the
    land.” (Ibid.) Later, in rebutting the arguments advanced
    against Proposition 4, its advocates stated, “By placing the
    names of all recognized candidates on the ballot the Secretary of
    State can help ensure that Californians have a chance to choose
    which candidate they wish to represent their party. California
    is the most populous state in the Union and serves as a cross
    section of the entire nation. It is only fitting that our
    presidential primary should be important in the selection of
    presidential nominees. [¶] The open presidential primary will
    free the voters of California to choose their own candidates for
    President of the United States and take the decision out of the
    smoke-filled rooms.” (June 1972 Ballot Pamp., supra, rebuttal
    to argument against Prop. 4, p. 11, italics added.)
    The opponents of Proposition 4, meanwhile, argued in
    their statements to voters within the ballot materials that the
    34
    PATTERSON v. PADILLA
    Opinion of the Court by Cantil-Sakauye, C. J.
    existing regime did not meaningfully impede the ability of
    leading candidates for president to appear on the primary ballot.
    They explained that “[t]o appear on the ballot, a candidate and
    his supporters need only gather a reasonable number of
    signatures of registered voters who wish to have the candidate’s
    name placed on the ballot.” (June 1972 Ballot Pamp., supra,
    argument against Prop. 4, p. 11.) Thus, with regard to Richard
    Nixon and Hubert Humphrey, the Republican and Democratic
    Party nominees in 1968 who had not participated in that
    spring’s California primary, “if one or both of those men had
    desired to place their name before their own party members in
    California in June 1968, they could have done so. There is
    absolutely nothing in present law which prevented them from
    entering the primary. For their own reasons, they chose not to
    do so.” (Id., rebuttal to argument in favor of Proposition 4,
    p. 10.)
    The opponents of Proposition 4 characterized the measure
    as objectionable because it would deny future presidential
    candidates the right to similarly choose whether to participate
    in the state primary. They asserted, “Proposition 4 forces a
    candidate to enter the California primary. This means that he
    must commit an immense amount of time and money to a
    campaign here, even though he may feel that his chances for the
    nomination might better be served by using that time and
    money elsewhere.” (June 1972 Ballot Pamp., supra, argument
    against Prop. 4, at p. 11.) The opponents maintained that “each
    presidential candidate should be free to decide which primaries
    he will enter, and Proposition 4 will deny such candidates their
    35
    PATTERSON v. PADILLA
    Opinion of the Court by Cantil-Sakauye, C. J.
    freedom of decision.”     (Id., rebuttal to argument in favor of
    Prop. 4, p. 10.)17
    The consistent characterizations of Proposition 4 within
    the ballot materials provided to voters at the June 1972 primary
    election illuminate the intent behind this measure. They
    establish that this legislative constitutional amendment
    responded to concerns that voters in previous California
    presidential primary elections had not consistently been
    provided with an adequate choice among candidates for
    president. To address this problem, the proposition upended the
    preexisting system, in which all candidates had to take
    affirmative steps to appear on the primary election ballot, and
    17
    Analyses of Senate Constitutional Amendment No. 3
    (1971 Reg. Sess.) that were prepared before Proposition 4 came
    before the electorate for approval reflect a similar
    understanding of the ballot measure. An analysis by the
    Assembly Committee on Elections and Reapportionment stated
    that the measure “would place on the . . . ballot the question
    whether California should have an ‘open’ Presidential primary.
    Under the measure the Secretary of State would be required to
    place all publicly recognized candidates for President on the
    primary ballot. Other candidates could qualify by petition.
    A candidate could withdraw by filing an affidavit that he is not
    a candidate.” (Assem. Com. on Elections and Reapportionment,
    Analysis of Sen. Const. Amend. No. 3 (1971 Reg. Sess.) p. 1,
    italics added.) A summary by the Legislature’s Constitutional
    Amendments Committee similarly explained that the measure
    “[r]equires [the] Secretary of State to place all publicly recognized
    candidates for President on the primary ballot.                 Other
    candidates could qualify by petition. Any candidate could
    withdraw his name by filing an affidavit with the Secretary of
    State stating that he is not a candidate.” (Const. Amends. Com.,
    Final Summary of Selected Legislation Relating to Amending
    the Cal. Const. (1971 Reg. Sess.) p. 7, italics added.)
    36
    PATTERSON v. PADILLA
    Opinion of the Court by Cantil-Sakauye, C. J.
    had sometimes declined to do so. That paradigm was replaced
    by one in which the Secretary of State must place on the ballot
    all persons found to be “recognized . . . throughout the nation or
    throughout California” as candidates for president within
    parties that qualify for the primary election (along with
    candidates who qualify through the petition process), except for
    candidates who file affidavits of noncandidacy.18
    C. Subsequent Developments
    The foregoing establishes that when Proposition 4 was
    approved by voters, it was understood to require that all persons
    identified as “recognized candidates throughout the nation or
    throughout California for the office of President of the United
    States” be included on the appropriate primary ballot, absent an
    affidavit of noncandidacy. The subsequent affirmation and
    implementation of the ballot reform effected by Proposition 4
    manifest a similar understanding.
    First, at the November 1972 general election, voters
    approved Proposition 7. This proposition adopted several
    recommendations of the Constitutional Revision Commission
    18
    These ballot materials also clarify that the affidavit of
    noncandidacy that would remove a “recognized” candidate for
    president from the ballot must do more than merely disavow
    participation in the California primary. The argument in favor
    of Proposition 4 stated, “Persons placed on the ballot and
    wishing to be removed may withdraw simply by filing an
    affidavit that they are not a candidate for President.” (June 1972
    Ballot Pamp., supra, argument in favor of Prop. 4, p. 10, italics
    added.) The arguments made by the measure’s opponents in the
    ballot materials, such as their assertion that it would deny
    presidential candidates their “freedom of decision” regarding
    “which primaries [to] enter” (id., rebuttal to argument in favor
    of Prop. 4, p. 10), carry similar connotations.
    37
    PATTERSON v. PADILLA
    Opinion of the Court by Cantil-Sakauye, C. J.
    regarding article II of the state Constitution, relating to
    elections. Among its provisions, Proposition 7 renumbered
    article II, section 8 of the state Constitution as article II, section
    4, and revised the introductory language of this section to
    provide (the italicized language being added through the
    proposition), “[t]he Legislature shall provide for primary
    elections for partisan offices, including an open presidential
    primary whereby the candidates on the ballot are those found
    by the Secretary of State to be recognized candidates throughout
    the nation or throughout California for the office of President of
    the United States, and those whose names are placed on the
    ballot by petition, but excluding any candidate who has
    withdrawn by filing an affidavit that he is not a candidate.”
    (Ballot Pamp., Gen. Elec. (Nov. 7, 1972) text of Prop. 7, appen.
    p. 9, italics added (hereafter November 1972 Ballot
    Pamphlet).)19
    Concerning this provision, opponents of Proposition 7
    revived an argument that had been made against Proposition 4
    at the preceding June 1972 primary election, asserting that the
    electorate should vote against the later measure because voters
    should not allow “the Secretary of State in his judgment and his
    judgment alone [to] pass[] on the candidate’s ‘recognition,’ and
    thus decid[e] as a practical matter which candidates will be
    voted on by the people. This is too important a matter to be left
    to the judgment of any one person.” (Nov. 1972 Ballot Pamp.,
    19
    A subsequent amendment to the Constitution, approved
    by the voters as Proposition 14 in June 1976, shifted this text
    (with its language regarding the affidavit of noncandidacy
    having been made gender-neutral through the intervening
    passage of Prop. 11 in November 1974) to article II, section 5 of
    the Constitution.
    38
    PATTERSON v. PADILLA
    Opinion of the Court by Cantil-Sakauye, C. J.
    supra, argument against Prop. 7, p. 20.) The proponents of
    Proposition 7 cast the issue as already settled by Proposition 4,
    explaining, “The open presidential primary was added to the
    Constitution by the people in June 1972. A ‘Yes’ vote merely
    renumbers that provision to conform to other language in Article
    II.” (Nov. 1972 Ballot Pamp., supra, rebuttal to argument
    against Prop. 7, p. 20.) Nothing associated with this back-and-
    forth, which implicitly equated a candidate’s “ ‘recognition’ ”
    (id., argument against Prop. 7, p. 20) with that candidate’s
    appearance on the primary ballot, suggests a view that under
    the Constitution as amended earlier that year through
    Proposition 4, the Legislature retained the authority to adopt
    disclosure requirements for presidential candidates that could
    function to exclude from the ballot even “recognized candidates
    throughout the nation or throughout California for the office of
    President of the United States.”
    Actions taken to implement Proposition 4 shortly after its
    approval also offer no indication of such an understanding. Two
    years after Proposition 4 passed, the Legislature enacted the
    Alquist Open Presidential Primary Act (Stats. 1974, ch. 1184).
    This statute revamped the procedures applicable to the
    Democratic Party presidential primary. As enacted, the sole
    requirement within this statute for inclusion on a presidential
    primary ballot was that a candidate be deemed “generally
    advocated for or recognized in the news media throughout the
    United States or California as actively seeking the nomination
    of the Democratic Party for President of the United States.” (See
    Stats. 1974, ch. 1184, § 2, p. 2537 [Elec. Code, former § 6310].)
    Substantively similar language was included in other
    presidential primary laws, applicable to other political parties,
    passed by the Legislature shortly thereafter. (See Elec. Code,
    39
    PATTERSON v. PADILLA
    Opinion of the Court by Cantil-Sakauye, C. J.
    former § 6010, added by Stats. 1975, ch. 1048, § 2, p. 2468; Elec.
    Code, former § 6210, added by Stats. 1975, ch. 1056, § 3, p. 2509;
    Elec. Code, former § 6110, added by Stats. 1975, ch. 1060, § 3,
    p. 2569.)
    By contemplating that a presidential candidate would
    appear on the appropriate primary ballot when found to be
    “generally advocated for or recognized” in the specified manner,
    these statutes and their present-day counterparts (Elec. Code,
    §§ 6041, 6340, subd. (a), 6520, subd. (a), 6720, 6851) convey a
    conception of article II, section 5(c) that is consistent with the
    one we adopt. As with the approval of Proposition 7 by the
    electorate, nothing within these laws implies a view that the
    Legislature can adopt disclosure requirements for presidential
    candidates that, if not complied with, would keep persons
    determined to be “recognized candidates throughout the nation
    or throughout California for the office of President of the United
    States” from appearing on a primary ballot.
    Similarly, there is no indication that the Secretary of State
    has traditionally construed article II, section 5(c) or its
    predecessor     provisions     as     contemplating     additional
    requirements for appearing on a presidential primary ballot,
    unrelated to whether someone is a “recognized candidate[]
    throughout the nation or throughout California for the office of
    President of the United States.” As discussed ante, when
    Secretaries of State have disclosed the factors they took into
    account in deciding whether a person qualified to appear as a
    candidate on a presidential primary ballot, these considerations
    all have had a reasonable relationship to whether a candidate
    was known throughout the nation or California, or was actively
    participating in the presidential race. (E.g., Sect. of State 2008
    Presidential Candidate Announcement, supra, at p. 1; Sect. of
    40
    PATTERSON v. PADILLA
    Opinion of the Court by Cantil-Sakauye, C. J.
    State 1976 Presidential Candidate Announcement, supra, at
    p. 1.)
    Last, although as has been explained there was no
    discussion of article II, section 5(c) in connection with legislative
    deliberations over Senate Bill No. 27 (2019-2020 Reg. Sess.),
    such a conversation did occur when the Legislature debated
    Senate Bill No. 505, which was enrolled and signed by the
    Governor on the same days as Senate Bill No. 27. Committee
    analyses of Senate Bill No. 505 reflect a common understanding
    that under article II, section 5(c), all presidential candidates
    found to be “recognized . . . throughout the nation or throughout
    California” must appear on the appropriate qualifying party’s
    ballot unless an affidavit of noncandidacy is filed. Two of these
    analyses state that Proposition 4 “placed on the 1972 primary
    ballot the question whether California should have a
    Presidential primary that required the SOS [Secretary of State]
    to place all publicly recognized candidates for President on the
    primary ballot.” (Sen. Com. on Elections and Const. Amends.,
    Analysis of Sen. Bill No. 505 (2019-2020 Reg. Sess.) as amended
    March 25, 2019, p. 5; Sen. Rules Com., Office of Floor Analyses,
    Analysis of Sen. Bill No. 505 (2019-2020 Reg. Sess.) as amended
    May 30, 2019, at p. 6.)
    In short, by all available indications, for more than four
    decades after Proposition 4’s approval in 1972, the electorate,
    the executive, and the Legislature all interpreted the
    constitutional text now found at article II, section 5(c) similarly
    to how we construe it, i.e., as requiring an open presidential
    primary in which all persons within qualifying parties found to
    be “recognized candidates throughout the nation or throughout
    California for the office of President of the United States” are to
    be included on the appropriate presidential primary ballot.

    PATTERSON v. PADILLA
    Opinion of the Court by Cantil-Sakauye, C. J.
    D. The Act’s Income Tax Return Disclosure
    Requirement Conflicts with Article II, Section
    5(c) and Cannot Be Enforced
    It follows from the discussion above that insofar as
    sections 6883 and 6884 of the Elections Code make a
    presidential candidate’s disclosure of income tax returns an
    absolute prerequisite for having the Secretary of State print the
    candidate’s name on a primary ballot, this requirement conflicts
    with the more inclusive presidential primary that the electorate
    endorsed when it approved Proposition 4.20
    20
    In his preliminary opposition, respondent argued that
    petitioners lack standing to pursue a writ of mandate, and that
    section 13314 of the Elections Code makes the Superior Court
    for the County of Sacramento the exclusive venue for this action.
    (Elec. Code, § 13314, subds. (a)(1), (b).) His response to our
    order to show cause stated that it incorporated by reference the
    arguments made in the preliminary opposition, but respondent
    did not otherwise renew these arguments in responding to our
    order to show cause — even as he advanced other reasons why
    no writ should issue.
    Assuming these arguments remain before us, they lack
    merit. We perceive no standing issue that keeps us from
    deciding the important issues presented in the petition. (See
    Code Civ. Proc., § 1086; Elec. Code, § 13314, subd. (a)(1); Save
    the Plastic Bag Coalition v. City of Manhattan Beach (2011)
    
    52 Cal. 4th 155
    , 166, 170, fn. 5; Weatherford v. City of San Rafael
    (2017) 2 Cal.5th 1241, 1247-1248.) Meanwhile, article VI,
    section 10 of the California Constitution vests this court with
    “original jurisdiction in proceedings for extraordinary relief in
    the nature of mandamus.” Although Elections Code section
    13314, subdivision (b) states that “[v]enue for a proceeding
    under this section shall be exclusively in Sacramento County
    [when]: [¶] (1) The Secretary of State is named as a real party
    in interest or as a respondent,” we do not read this provision as
    depriving this court of its original jurisdiction to entertain
    42
    PATTERSON v. PADILLA
    Opinion of the Court by Cantil-Sakauye, C. J.
    As has been explained, Proposition 4 was approved by the
    electorate after voters had been denied the opportunity in
    previous California primary elections to vote for or against
    leading candidates for president, with several prominent
    candidates for that office having declined to take the steps
    necessary to qualify for the primary ballot. To avoid a
    recurrence in future primaries, Proposition 4 instituted a
    system whereby all persons within qualifying parties who are
    found to be “recognized candidates throughout the nation or
    throughout California for the office of President of the United
    States” must be included on the appropriate presidential
    primary ballot, unless they file an affidavit of noncandidacy,
    along with candidates who qualify for the ballot through the
    petition process. This reform advanced the interest of California
    voters in more consistently having direct and substantial
    influence in the primary process.
    Allowing the income tax return disclosure requirement
    before us to stand could effectively revoke article II, section
    5(c)’s guarantee to voters of a choice among all “recognized”
    candidates for president who do not file affidavits of
    noncandidacy. The statutory prerequisite, if not complied with,
    would exclude from the ballot even someone who is actively
    seeking the presidential nomination of a political party that
    participates in the primary election, and is widely regarded as
    a leading contender for that nomination — precisely the sort of
    presidential candidate that article II, section 5(c) specifies must
    petitions such as the one at bar. (See Vandermost v. Bowen
    (2012) 
    53 Cal. 4th 421
    , 451; California Redevelopment Assn. v.
    Matosantos (2011) 
    53 Cal. 4th 231
    , 252-253.)
    43
    PATTERSON v. PADILLA
    Opinion of the Court by Cantil-Sakauye, C. J.
    appear on the ballot, absent the filing of an affidavit of
    noncandidacy.
    In arguing that the Legislature may properly condition a
    presidential candidate’s access to the primary ballot on
    compliance with the Act’s disclosure requirement, respondent
    emphasizes the Legislature’s broad authority to provide for a
    system of primary elections, including presidential primaries.
    (E.g., Libertarian Party v. Eu, supra, 28 Cal.3d at p. 540.) Prior
    to the adoption of Proposition 4, we recognized that this
    authority includes the ability to enact reasonable rules that may
    operate to exclude some candidates from the primary ballot.
    (E.g., Communist Party v. Peek, supra, 20 Cal.2d at pp. 542-
    545.) But as discussed ante, the language and history of article
    II, section 5(c) establish that this general authority does not
    include the more specific power to exclude persons found to be
    “recognized candidates throughout the nation or throughout
    California for the office of President of the United States” from
    appearing on the ballot of a party that participates in the
    primary election. Whatever the Legislature’s authority may be
    to define ground rules for presidential primary elections, article
    II, section 5(c) also includes a requirement of an inclusive ballot
    that such legislation must respect and embrace.
    Respondent further asserts that the Legislature’s general
    power to provide for primary elections makes it both inevitable
    and appropriate that it will have some role in defining, directly
    or indirectly, who will appear on the primary ballot as a
    candidate for president. Making this point, respondent states
    in his briefing that “[t]he Legislature has already permissibly
    acted to define who may be a ‘recognized candidate’ through
    laws that only allow candidates identified with qualified parties
    to appear on ballots.”
    44
    PATTERSON v. PADILLA
    Opinion of the Court by Cantil-Sakauye, C. J.
    It is true that under current law, individuals who compete
    for the presidential nominations of parties that have not
    qualified to participate in the state primary election (see Elec.
    Code, § 5100) will not have their names printed on the primary
    election ballot, because with these candidates, there is no party
    ballot to appear on. This is true regardless of whether such a
    candidate might meet generic criteria for being “recognized . . .
    throughout the nation or throughout California” as a candidate
    “for the office of President of the United States.” We have no
    need here, however, to decide whether the presidential primary
    laws of this state relating to subjects such as the necessary
    qualifications of participating political parties also may
    implicate article II, section 5(c).21 Respondent’s observation
    regarding the exclusion of candidates from nonparticipating
    parties is adequately addressed by observing that whatever
    questions may exist about the intent behind Proposition 4, this
    measure manifestly sought to provide California voters eligible
    to vote for a political party that participates in the primary
    election with the opportunity to choose among all “recognized”
    candidates seeking the presidential nomination of that party —
    except, again, for those candidates who have filed affidavits of
    noncandidacy. Insofar as the Act would make such a candidate’s
    disclosure of income tax returns a requirement for inclusion on
    a qualifying party’s primary ballot, its provisions conflict with
    this intent, and are therefore unconstitutional.
    21
    Nor, given the limited ambit of article II, section 5(c), do
    we have occasion to opine on conditions for appearing on the
    primary ballot that may be placed on candidates for political
    offices other than President of the United States.
    45
    PATTERSON v. PADILLA
    Opinion of the Court by Cantil-Sakauye, C. J.
    Finally, respondent observes that Proposition 4 omitted
    language found in the earlier proposed legislation relating to the
    presidential primary ballot, discussed ante, that was introduced
    between 1965 and 1971 but failed to become law. These
    unsuccessful measures all had provided that the Secretary of
    State would determine “in his sole discretion” whether a
    candidate was sufficiently “recognized” to be included on the
    primary ballot. (Sen. Bill. No. 3 (1971 Reg. Sess.) as introduced
    Jan. 4, 1971, § 2; Sen. Bill. No. 3 (1969 Reg. Sess.) as introduced
    Jan. 7, 1969, § 2; Sen. Bill No. 145 (1968 Reg. Sess.) as
    introduced Jan. 30, 1968, § 2; Sen. Bill No. 586 (1967 Reg. Sess.)
    as introduced Mar. 14, 1967, § 2; Assem. Bill No. 1414 (1965
    Reg. Sess.) § 2.)
    Respondent would have us infer from the absence of this
    “sole discretion” language in Proposition 4 that voters, in
    approving this measure, intended for the Legislature to have the
    authority to exclude even “recognized” candidates for president
    from the primary ballot. This argument reads far too much into
    this shift in phrasing. In light of the text and history of article
    II, section 5(c), the most that can be said is that the Legislature
    might properly claim some role in defining when someone is
    “recognized . . . throughout the nation or throughout California”
    as a candidate “for the office of President of the United States,”
    with the precise parameters of any such authority to be defined
    another day, in another case. Yet article II, section 5(c) also
    clearly prohibits the Legislature from imposing prerequisites
    such as the income tax return disclosure requirement before us
    46
    PATTERSON v. PADILLA
    Opinion of the Court by Cantil-Sakauye, C. J.
    that a presidential candidate who is so recognized also must
    satisfy in order to appear on a primary ballot.22
    E. Petitioners Are Entitled to a Writ of Mandate
    Respondent argues that no writ of mandate should issue
    because the Secretary of State has some discretion in
    determining who is “recognized . . . throughout the nation or
    throughout California” as a candidate “for the office of President
    of the United States,” and therefore, according to respondent,
    “there is no purely ministerial duty that can be mandated by
    this Court.” But “a writ of mandate is available, in the absence
    of a ‘plain, speedy, and adequate remedy, in the ordinary course
    of law’ (Code Civ. Proc., § 1086), against the implementation of
    an invalid statute.” (Hotel Employees & Restaurant Employees
    Internat. Union v. Davis (1999) 
    21 Cal. 4th 585
    , 590.) We have
    in the past issued writs of mandate directing state officers not
    to enforce statutes we found unconstitutional. (Hardie v. Eu
    (1976) 
    18 Cal. 3d 371
    , 380; Sail’er Inn, Inc. v. Kirby (1971)
    22
    Moreover, it is debatable at best whether this difference in
    phrasing between the unsuccessful earlier measures and
    Proposition 4 is even material to the interpretative question
    before the court. This distinction was not brought before the
    electorate in the ballot materials associated with this
    proposition. In fact, voters were told by the opponents of
    Proposition 4 that, in this respect, the amendment would
    function similarly to the scheme envisioned by the earlier
    measures. (June 1972 Ballot Pamp., supra, argument against
    Prop. 4, p. 11 [asserting that the proposition would “give[] just
    one man, the California Secretary of State, the right to
    determine which names will be placed on the ballot for the
    highest office in this country”].)

    Opinion of the Court by Cantil-Sakauye, C. J.
    
    5 Cal. 3d 1
    , 22; see also Planned Parenthood Affiliates v. Van de
    Kamp (1986) 
    181 Cal. App. 3d 245
    , 263 [“[p]rohibitory mandate
    has also been used to restrain state officials from enforcing
    ministerial statutory provisions found to be unconstitutional”].)
    This case is similar, and we perceive no limitation on the writ
    that would prevent it from being issued here.
    III. DISPOSITION
    We hold that Elections Code sections 6883 and 6884 are
    invalid under article II, section 5(c) of the California
    Constitution insofar as they purport to require someone who is
    “recognized . . . throughout the nation or throughout California”
    as a candidate for the office of President of the United States to
    file with the Secretary of State federal income tax returns as a
    necessary condition for appearing on the primary election ballot
    of a political party that has qualified to participate in that
    election. In accordance with this holding, let a peremptory writ
    of mandate issue that directs the Secretary of State to refrain
    from enforcing Elections Code sections 6883 and 6884 as to such
    candidates. Our judgment is final forthwith. (See Vandermost
    v. Bowen, supra, 53 Cal.4th at p. 486; California Redevelopment
    Assn. v. Matosantos, supra, 53 Cal.4th at p. 276.)

    48
    PATTERSON v. PADILLA
    S257302
    Concurring Opinion by Justice Cuéllar
    Our holding in this case is narrow. The Legislature cannot
    bar from the presidential primary election ballot a candidate
    “found by the Secretary of State to be recognized . . . throughout
    the nation or throughout California” (Cal. Const., art. II, § 5,
    subd. (c)), even if that candidate fails to disclose five years’ worth
    of federal tax returns as required by Elections Code section
    6883. The limited scope of this holding leaves intact key
    portions of the Presidential Tax Transparency and
    Accountability Act. (Stats. 2019, ch. 121.)
    Nothing in the court’s decision, for example, prohibits the
    Legislature from finding that “as one of the largest centers of
    economic activity in the world, the State of California has a
    special interest in the President refraining from corrupt or self-
    enriching behavior while in office.” (Elec. Code, § 6881.) And no
    party to this case disputed the fact that voters “can better
    estimate the risks of any given Presidential candidate engaging
    in corruption or the appearance of corruption if they have access
    to candidates’ tax returns,” given how a “Presidential
    candidate’s income tax returns provide voters with essential
    information regarding the candidate’s potential conflicts of
    interest, business dealings, financial status, and charitable
    donations.” (Ibid.)
    Nor does our holding prohibit the Legislature from
    encouraging or seeking such information from a presidential
    1
    PATTERSON v. PADILLA
    Cuéllar, J., concurring
    candidate, so long as provision of that information is not a
    condition for the recognized candidate’s name to appear on
    California’s primary election ballot. But it’s worth noting, too,
    that an interest in the financial transparency of those seeking
    to become the Chief Executive of the United States is not one of
    those attributes distinctive to California. Indeed, it’s quite easy
    to find the tax returns disclosed by our nation’s Presidents, with
    only a few exceptions, dating back to 1932 on various news and
    stand-alone websites, as well as the tax returns disclosed by
    many of the unsuccessful candidates over the past 40 years. The
    general availability of this information reflects an ongoing
    public and historical interest in the financial honesty and
    competence of those seeking the highest office in the land.
    That the public, through moral suasion or a legal
    requirement crafted by its elected representatives, has so often
    succeeded in forcing disclosure of essential financial information
    about political candidates would not have come as a surprise to
    our nation’s founders. As Thomas Jefferson cautioned in the
    first years after independence, “[t]he time to guard against
    corruption and tyranny is before they shall have gotten their
    hold on us. It is better to keep the wolf out of the fold, than to
    trust to drawing his teeth and talons after he shall have
    entered.”      (Jefferson, The Jefferson Cyclopedia:             A
    Comprehensive Collection of the Views of Thomas Jefferson
    (Foley ed. 1900) p. 210.) The force of that warning remains
    undiluted by today’s decision.
