    ARIZONA STATE LEGISLATURE v. ARIZONA
    INDEPENDENT REDISTRICTING COMMISSION ET AL.
    APPEAL FROM THE UNITED STATES DISTRICT COURT FOR THE
    DISTRICT OF ARIZONA
    No. 13–1314. Argued March 2, 2015—Decided June 29, 2015
    Under Arizona’s Constitution, the electorate shares lawmaking author-
    ity on equal footing with the Arizona Legislature. The voters may
    adopt laws and constitutional amendments by ballot initiative, and
    they may approve or disapprove, by referendum, measures passed by
    the Legislature. Ariz. Const., Art. IV, pt. 1, §1. “Any law which may
    be enacted by the Legislature . . . may be enacted by the people under
    the Initiative.” Art. XXII, §14.
    In 2000, Arizona voters adopted Proposition 106, an initiative
    aimed at the problem of gerrymandering. Proposition 106 amended
    Arizona’s Constitution, removing redistricting authority from the Ar-
    izona Legislature and vesting it in an independent commission, the
    Arizona Independent Redistricting Commission (AIRC). After the
    2010 census, as after the 2000 census, the AIRC adopted redistricting
    maps for congressional as well as state legislative districts. The Ari-
    zona Legislature challenged the map the Commission adopted in
    2012 for congressional districts, arguing that the AIRC and its map
    violated the “Elections Clause” of the U. S. Constitution, which pro-
    vides: “The Times, Places and Manner of holding Elections for Sena-
    tors and Representatives shall be prescribed in each State by the
    Legislature thereof; but the Congress may at any time by Law make
    or alter such Regulations.” Because “Legislature” means the State’s
    representative assembly, the Arizona Legislature contended, the
    Clause precludes resort to an independent commission, created by in-
    itiative, to accomplish redistricting. A three-judge District Court
    held that the Arizona Legislature had standing to sue, but rejected
    its complaint on the merits.

    INDEPENDENT REDISTRICTING COMM’N
    Syllabus
    1. The Arizona Legislature has standing to bring this suit. In
    claiming that Proposition 106 stripped it of its alleged constitutional
    prerogative to engage in redistricting and that its injury would be
    remedied by a court order enjoining the proposition’s enforcement,
    the Legislature has shown injury that is ‘concrete and particularized’
    and ‘actual or imminent,’ ” Arizonans for Official English v. Arizona,
    
    520 U.S. 43
    , 64, “fairly traceable to the challenged action,” and “re-
    dressable by a favorable ruling,” Clapper v. Amnesty Int’l USA, 568
    U. S. ___, ___. Specifically, Proposition 106, together with the Arizo-
    na Constitution’s ban on efforts by the Arizona Legislature to under-
    mine the purposes of an initiative, would “completely nullif[y]” any
    vote by the Legislature, now or “in the future,” purporting to adopt a
    redistricting plan. Raines v. Byrd, 
    521 U.S. 811
    , 823–824. Pp. 9–15.
    2. The Elections Clause and 
    2 U.S. C
    . §2a(c) permit Arizona’s use
    of a commission to adopt congressional districts. Pp. 15–35.
    (a) Redistricting is a legislative function to be performed in ac-
    cordance with the State’s prescriptions for lawmaking, which may in-
    clude the referendum, Ohio ex rel. Davis v. Hildebrant, 
    241 U.S. 565
    ,
    567, and the Governor’s veto, Smiley v. Holm, 
    285 U.S. 355
    , 369.
    While exercise of the initiative was not at issue in this Court’s prior
    decisions, there is no constitutional barrier to a State’s empowerment
    of its people by embracing that form of lawmaking. Pp. 15–19.
    (b) Title 
    2 U.S. C
    . §2a(c)—which provides that, “[u]ntil a State is
    redistricted in the manner provided by the law thereof after any ap-
    portionment,” it must follow federally prescribed redistricting proce-
    dures—permits redistricting in accord with Arizona’s initiative.
    From 1862 through 1901, apportionment Acts required a State to fol-
    low federal procedures unless “the [state] legislature” drew district
    lines. In 1911, Congress, recognizing that States had supplemented
    the representative legislature mode of lawmaking with a direct law-
    making role for the people, replaced the reference to redistricting by
    the state “legislature” with a reference to redistricting of a State “in
    the manner provided by the laws thereof.” §4, 37 Stat. 14. The Act’s
    legislative history “leaves no . . . doubt,” 
    Hildebrant, 241 U.S., at 568
    , that the change was made to safeguard to “each state full au-
    thority to employ in the creation of congressional districts its own
    laws and regulations.” 47 Cong. Rec. 3437. “If they include the initi-
    ative, it is included.” 
    Id., at 3508.
    Congress used virtually identical
    language in enacting §2a(c) in 1941. This provision also accords full
    respect to the redistricting procedures adopted by the States. Thus,
    so long as a State has “redistricted in the manner provided by the law
    thereof”—as Arizona did by utilizing the independent commission
    procedure in its Constitution—the resulting redistricting plan be-
    comes the presumptively governing map.

    Syllabus
    Though four of §2a(c)’s five default redistricting procedures—
    operative only when a State is not “redistricted in the manner pro-
    vided by [state] law”—have become obsolete as a result of this Court’s
    decisions embracing the one-person, one-vote principle, this infirmity
    does not bear on the question whether a State has been “redistricted
    in the manner provided by [state] law.” Pp. 19–23.
    (c) The Elections Clause permits the people of Arizona to provide
    for redistricting by independent commission. The history and pur-
    pose of the Clause weigh heavily against precluding the people of Ar-
    izona from creating a commission operating independently of the
    state legislature to establish congressional districts. Such preclusion
    would also run up against the Constitution’s animating principle that
    the people themselves are the originating source of all the powers of
    government. Pp. 24–35.
    (1) The dominant purpose of the Elections Clause, the histori-
    cal record bears out, was to empower Congress to override state elec-
    tion rules, not to restrict the way States enact legislation. See Inter
    Tribal Council of Ariz., 570 U. S., at ___. Ratification arguments in
    support of congressional oversight focused on potential abuses by
    state politicians, but the legislative processes by which the States
    could exercise their initiating role in regulating congressional elec-
    tions occasioned no debate. Pp. 25–27.
    (2) There is no suggestion that the Election Clause, by specify-
    ing “the Legislature thereof,” required assignment of congressional
    redistricting authority to the State’s representative body. It is char-
    acteristic of the federal system that States retain autonomy to estab-
    lish their own governmental processes free from incursion by the
    Federal Government. See, e.g., Alden v. Maine, 
    527 U.S. 706
    , 752.
    “Through the structure of its government, and the character of those
    who exercise government authority, a State defines itself as a sover-
    eign.” Gregory v. Ashcroft, 
    501 U.S. 452
    , 460. Arizona engaged in
    definition of that kind when its people placed both the initiative pow-
    er and the AIRC’s redistricting authority in the portion of the Arizo-
    na Constitution delineating the State’s legislative authority, Ariz.
    Const., Art. IV. The Elections Clause should not be read to single out
    federal elections as the one area in which States may not use citizen
    initiatives as an alternative legislative process. And reading the
    Clause to permit the use of the initiative to control state and local
    elections but not federal elections would “deprive several States of
    the convenience of having the elections for their own governments
    and for the national government” held at the same times and places,
    and in the same manner. The Federalist No. 61, p. 374 (Hamilton).
    Pp. 27–30.
    (3) The Framers may not have imagined the modern initiative
    4             ARIZONA STATE LEGISLATURE v. ARIZONA
    INDEPENDENT REDISTRICTING COMM’N
    Syllabus
    process in which the people’s legislative power is coextensive with the
    state legislature’s authority, but the invention of the initiative was in
    full harmony with the Constitution’s conception of the people as the
    font of governmental power. It would thus be perverse to interpret
    “Legislature” in the Elections Clause to exclude lawmaking by the
    people, particularly when such lawmaking is intended to advance the
    prospect that Members of Congress will in fact be “chosen . . . by the
    People of the several States,” Art. I, §2. Pp. 30–33.
    (4) Banning lawmaking by initiative to direct a State’s method
    of apportioning congressional districts would not just stymie at-
    tempts to curb gerrymandering. It would also cast doubt on numer-
    ous other time, place, and manner regulations governing federal elec-
    tions that States have adopted by the initiative method. As well, it
    could endanger election provisions in state constitutions adopted by
    conventions and ratified by voters at the ballot box, without involve-
    ment or approval by “the Legislature.” Pp. 33–35.

    ARIZONA STATE LEGISLATURE, APPELLANT v.
    ARIZONA INDEPENDENT REDISTRICTING
    COMMISSION ET AL.
    ON APPEAL FROM THE UNITED STATES DISTRICT COURT FOR
    THE DISTRICT OF ARIZONA
    [June 29, 2015]
    JUSTICE GINSBURG delivered the opinion of the Court.
    This case concerns an endeavor by Arizona voters to
    address the problem of partisan gerrymandering—the
    drawing of legislative district lines to subordinate adher­
    ents of one political party and entrench a rival party in
    power.1 “[P]artisan gerrymanders,” this Court has recog­
    nized, “[are incompatible] with democratic principles.”

    (KENNEDY, J., concurring in judg­
    ment). Even so, the Court in Vieth did not grant relief on
    the plaintiffs’ partisan gerrymander claim. The plurality
    held the matter nonjusticiable. 
    Id., at 281.
    JUSTICE
    KENNEDY found no standard workable in that case, but
    left open the possibility that a suitable standard might be
    identified in later litigation.

    1 The term “gerrymander” is a portmanteau of the last name of El-
    bridge Gerry, the eighth Governor of Massachusetts, and the shape of
    the electoral map he famously contorted for partisan gain, which
    included one district shaped like a salamander. See E. Griffith, The
    Rise and Development of the Gerrymander 16–19 (Arno ed. 1974).
    2        ARIZONA STATE LEGISLATURE v. ARIZONA
    INDEPENDENT REDISTRICTING COMM’N
    Opinion of the Court
    In 2000, Arizona voters adopted an initiative, Proposi­
    tion 106, aimed at “ending the practice of gerrymandering
    and improving voter and candidate participation in elec­
    tions.” App. 50. Proposition 106 amended Arizona’s Con­
    stitution to remove redistricting authority from the Ari-
    zona Legislature and vest that authority in an independent
    commission, the Arizona Independent Redistricting Com­
    mission (AIRC or Commission). After the 2010 census,
    as after the 2000 census, the AIRC adopted redistrict-
    ing maps for congressional as well as state legislative
    districts.
    The Arizona Legislature challenged the map the Com­
    mission adopted in January 2012 for congressional dis­
    tricts. Recognizing that the voters could control redistrict­
    ing for state legislators, Brief for Appellant 42, 47; Tr. of
    Oral Arg. 3–4, the Arizona Legislature sued the AIRC in
    federal court seeking a declaration that the Commission
    and its map for congressional districts violated the “Elec­
    tions Clause” of the U. S. Constitution. That Clause,
    critical to the resolution of this case, provides:
    “The Times, Places and Manner of holding Elections
    for Senators and Representatives, shall be prescribed
    in each State by the Legislature thereof; but the Con­
    gress may at any time by Law make or alter such
    Regulations . . . .” Art. I, §4, cl. 1.
    The Arizona Legislature’s complaint alleged that “[t]he
    word ‘Legislature’ in the Elections Clause means [specifi­
    cally and only] the representative body which makes the
    laws of the people,” App. 21, ¶37; so read, the Legislature
    urges, the Clause precludes resort to an independent
    commission, created by initiative, to accomplish redistrict­
    ing. The AIRC responded that, for Elections Clause pur­
    poses, “the Legislature” is not confined to the elected
    representatives; rather, the term encompasses all legisla­
    tive authority conferred by the State Constitution, includ­
    Cite as: 576 U. S. ____ (2015)            3
    Opinion of the Court
    ing initiatives adopted by the people themselves.
    A three-judge District Court held, unanimously, that the
    Arizona Legislature had standing to sue; dividing two to
    one, the Court rejected the Legislature’s complaint on the
    merits. We postponed jurisdiction and instructed the
    parties to address two questions: (1) Does the Arizona
    Legislature have standing to bring this suit? (2) Do the
    Elections Clause of the United States Constitution and 
    2 U.S. C
    . §2a(c) permit Arizona’s use of a commission to
    adopt congressional districts? 573 U. S. ___ (2014).
    We now affirm the District Court’s judgment. We hold,
    first, that the Arizona Legislature, having lost authority to
    draw congressional districts, has standing to contest the
    constitutionality of Proposition 106. Next, we hold that
    lawmaking power in Arizona includes the initiative proc-
    ess, and that both §2a(c) and the Elections Clause permit
    use of the AIRC in congressional districting in the same
    way the Commission is used in districting for Arizona’s
    own Legislature.

    Direct lawmaking by the people was “virtually unknown
    when the Constitution of 1787 was drafted.” Donovan &
    Bowler, An Overview of Direct Democracy in the American
    States, in Citizens as Legislators 1 (S. Bowler, T. Don-
    ovan, & C. Tolbert eds. 1998). There were obvious pre-
    cursors or analogues to the direct lawmaking operative
    today in several States, notably, New England’s town hall
    meetings and the submission of early state constitutions to
    the people for ratification. See Lowell, The Referendum in
    the United States, in The Initiative, Referendum and
    Recall 126, 127 (W. Munro ed. 1912) (hereinafter IRR); W.
    Dodd, The Revision and Amendment of State Constitu­
    4          ARIZONA STATE LEGISLATURE v. ARIZONA
    INDEPENDENT REDISTRICTING COMM’N
    Opinion of the Court
    tions 64–67 (1910).2 But it was not until the turn of the
    20th century, as part of the Progressive agenda of the era,
    that direct lawmaking by the electorate gained a foothold,
    largely in Western States. See generally Persily, The
    Peculiar Geography of Direct Democracy: Why the Initia­
    tive, Referendum and Recall Developed in the American
    West, 
    2 Mich. L
    . & Pol’y Rev. 11 (1997).
    The two main “agencies of direct legislation” are the
    initiative and the referendum. Munro, Introductory, in
    IRR 8. The initiative operates entirely outside the States’
    representative assemblies; it allows “voters [to] petition to
    propose statutes or constitutional amendments to be
    adopted or rejected by the voters at the polls.” D. Magleby,
    Direct Legislation 1 (1984). While the initiative allows
    the electorate to adopt positive legislation, the referendum
    serves as a negative check. It allows “voters [to] petition
    to refer a legislative action to the voters [for approval or
    disapproval] at the polls.” 
    Ibid. “The initiative [thus]
    corrects sins of omission” by representative bodies, while
    the “referendum corrects sins of commission.” Johnson,
    Direct Legislation as an Ally of Representative Govern­
    ment, in IRR 139, 142.
    In 1898, South Dakota took the pathmarking step of
    affirming in its Constitution the people’s power “directly
    [to] control the making of all ordinary laws” by initiative
    and referendum. Introductory, 
    id., at 9.

    2 The Massachusetts Constitution of 1780 is illustrative of the under­
    standing that the people’s authority could trump the state legislature’s.
    Framed by a separate convention, it was submitted to the people for
    ratification. That occurred after the legislature attempted to promul­
    gate a Constitution it had written, an endeavor that drew opposition
    from many Massachusetts towns. See J. Rakove, Original Meanings:
    Politics and Ideas in the Making of the Constitution 96–101 (1996); G.
    Wood, The Creation of the American Republic, 1776–1787, pp. 339–341

    Opinion of the Court
    not only to enact ordinary laws, but also to amend the
    State’s Constitution. J. Dinan, The American State Con­
    stitutional Tradition 62 (2006). By 1920, the people in 19
    States had reserved for themselves the power to initiate
    ordinary lawmaking, and, in 13 States, the power to initi­
    ate amendments to the State’s Constitution. 
    Id., at 62,
    and n. 132, 94, and n. 151. Those numbers increased to 21
    and 18, respectively, by the close of the 20th century.

    For the delegates to Arizona’s constitutional convention,
    direct lawmaking was a “principal issu[e].” J. Leshy, The
    Arizona State Constitution 8–9 (2d ed. 2013) (hereinafter
    Leshy). By a margin of more than three to one, the people
    of Arizona ratified the State’s Constitution, which included,
    among lawmaking means, initiative and referendum pro-
    visions. 
    Id., at 14–16,
    22. In the runup to Arizona’s ad­
    mission to the Union in 1912, those provisions generated
    no controversy.

       In particular, the Arizona Constitution “establishes the

    of government.” (internal quotation marks omitted)). The
    initiative, housed under the article of the Arizona Consti­
    tution concerning the “Legislative Department” and the
    section defining the State’s “legislative authority,” re­
    serves for the people “the power to propose laws and
    amendments to the constitution.” Art. IV, pt. 1, §1. The
    Arizona Constitution further states that “[a]ny law which
    may be enacted by the Legislature under this Constitution
    may be enacted by the people under the Initiative.”
    Art. XXII, §14. Accordingly, “[g]eneral references to the
    power of the ‘legislature’ ” in the Arizona Constitution
    “include the people’s right (specified in Article IV, part 1)
    to bypass their elected representatives and make laws
    directly through the initiative.” Leshy xxii.
    C
    Proposition 106, vesting redistricting authority in the
    AIRC, was adopted by citizen initiative in 2000 against a
    “background of recurring redistricting turmoil” in Arizona.
    Cain, Redistricting Commissions: A Better Political Buf-
    fer? 121 Yale L. J. 1808, 1831 (2012). Redistricting plans
    adopted by the Arizona Legislature sparked controversy in
    every redistricting cycle since the 1970’s, and several of
    those plans were rejected by a federal court or refused
    preclearance by the Department of Justice under the
    Voting Rights Act of 1965. See

    4 From Arizona’s admission to the Union in 1912 to 1940, no congres­

    Congress. K. Martis, The Historical Atlas of United States Congres­
    sional Districts, 1789–1983, p. 3 (1982) (Table 1). Court-ordered

    Aimed at “ending the practice of gerrymandering and
    improving voter and candidate participation in elections,”
    App. 50, Proposition 106 amended the Arizona Constitu­

    5 In the current climate of heightened partisanship, the AIRC has
    encountered interference with its operations. In particular, its depend­

    have proved problematic. In 2011, when the AIRC proposed boundaries

    INDEPENDENT REDISTRICTING COMM’N
    Opinion of the Court
    Several other States, as a means to curtail partisan
    gerrymandering, have also provided for the participation
    of commissions in redistricting. Some States, in common
    with Arizona, have given nonpartisan or bipartisan com­
    missions binding authority over redistricting.6 The Cali­
    fornia Redistricting Commission, established by popular
    initiative, develops redistricting plans which become
    effective if approved by public referendum.7 Still other
    States have given commissions an auxiliary role, advising
    the legislatures on redistricting,8 or serving as a “backup”
    in the event the State’s representative body fails to com­
    plete redistricting.9 Studies report that nonpartisan and
    bipartisan commissions generally draw their maps in a
    timely fashion and create districts both more competitive
    and more likely to survive legal challenge. See Miller &
    Grofman, Redistricting Commissions in the Western
    United States, 3 U. C. Irvine L. Rev. 637, 661, 663–664,

    Opinion of the Court
    http://azredistricting.org/Maps/Final-Maps/default.asp (all
    Internet materials as visited June 25, 2015, and included
    in Clerk of Court’s case file). Less than four months later,
    on June 6, 2012, the Arizona Legislature filed suit in the
    United States District Court for the District of Arizona,
    naming as defendants the AIRC, its five members, and the
    Arizona Secretary of State. The Legislature sought both a
    declaration that Proposition 106 and congressional maps
    adopted by the AIRC are unconstitutional, and, as affirm­
    ative relief, an injunction against use of AIRC maps for
    any congressional election after the 2012 general election.
    A three-judge District Court, convened pursuant to 
    28 U.S. C
    . §2284(a), unanimously denied a motion by the
    AIRC to dismiss the suit for lack of standing. The Arizona
    Legislature, the court determined, had “demonstrated that
    its loss of redistricting power constitute[d] a [sufficiently]
    concrete injury.” 
    997 F. Supp. 2d 1047
    , 1050 (2014). On
    the merits, dividing two to one, the District Court granted
    the AIRC’s motion to dismiss the complaint for failure to
    state a claim. Decisions of this Court, the majority con­
    cluded, “demonstrate that the word ‘Legislature’ in the
    Elections Clause refers to the legislative process used in
    [a] state, determined by that state’s own constitution and
    laws.” 
    Id., at 1054.
    As the “lawmaking power” in Arizona
    “plainly includes the power to enact laws through initia­
    tive,” the District Court held, the “Elections Clause per­
    mits [Arizona’s] establishment and use” of the Commis­
    sion. 
    Id., at 1056.
    Judge Rosenblatt dissented in part.
    Proposition 106, in his view, unconstitutionally denied
    “the Legislature” of Arizona the “ability to have any out­
    come-defining effect on the congressional redistricting
    process.” 
    Id., at 1058.
       We postponed jurisdiction, and now affirm.

    We turn first to the threshold question: Does the Ari­
    10        ARIZONA STATE LEGISLATURE v. ARIZONA
    INDEPENDENT REDISTRICTING COMM’N
    Opinion of the Court
    zona Legislature have standing to bring this suit? Trained
    on “whether the plaintiff is [a] proper party to bring [a
    particular lawsuit,]” standing is “[o]ne element” of the
    Constitution’s case-or-controversy limitation on federal
    judicial authority, expressed in Article III of the Constitu­
    tion. Raines v. Byrd, 
    521 U.S. 811
    , 818 (1997). “To qual­
    ify as a party with standing to litigate,” the Arizona Legis­
    lature “must show, first and foremost,” injury in the form
    of “ ‘invasion of a legally protected interest’ that is ‘con­
    crete and particularized’ and ‘actual or imminent.’ ” Ari-
    zonans for Official English v. Arizona, 
    520 U.S. 43
    , 64
    (1997) (quoting Lujan v. Defenders of Wildlife, 
    504 U.S. 555
    , 560 (1992)). The Legislature’s injury also must be
    “fairly traceable to the challenged action” and “redressable
    by a favorable ruling.” Clapper v. Amnesty Int’l USA, 568
    U. S. ___, ___ (2013) (slip op., at 10) (internal quotation
    marks omitted).
    The Arizona Legislature maintains that the Elections
    Clause vests in it “primary responsibility” for redistricting.
    Brief for Appellant 51, 53. To exercise that responsibility,
    the Legislature urges, it must have at least the opportun-
    ity to engage (or decline to engage) in redistricting before
    the State may involve other actors in the redistricting
    process. See 
    id., at 51–53.
    Proposition 106, which gives
    the AIRC binding authority over redistricting, regardless
    of the Legislature’s action or inaction, strips the Legisla­
    ture of its alleged prerogative to initiate redistricting.
    That asserted deprivation would be remedied by a court
    order enjoining the enforcement of Proposition 106. Al-
    though we conclude that the Arizona Legislature does not
    have the exclusive, constitutionally guarded role it asserts,
    see infra, at 24–35, one must not “confus[e] weakness on
    the merits with absence of Article III standing.” Davis v.
    United States, 564 U. S. ___, ___, n. 10 (2011) (slip op., at
    19, n. 10); see Warth v. Seldin, 
    422 U.S. 490
    , 500 (1975)
    (standing “often turns on the nature and source of the
    Cite as: 576 U. S. ____ (2015)            11
    Opinion of the Court
    claim asserted,” but it “in no way depends on the merits”
    of the claim).
    The AIRC argues that the Legislature’s alleged injury is
    insufficiently concrete to meet the standing requirement
    absent some “specific legislative act that would have taken
    effect but for Proposition 106.” Brief for Appellees 20. The
    United States, as amicus curiae, urges that even more is
    needed: the Legislature’s injury will remain speculative,
    the United States contends, unless and until the Arizona
    Secretary of State refuses to implement a competing redis­
    tricting plan passed by the Legislature. Brief for United
    States 14–17. In our view, the Arizona Legislature’s suit
    is not premature, nor is its alleged injury too “conjectural”
    or “hypothetical” to establish standing. Defenders of Wild-
    
    life, 504 U.S., at 560
    (internal quotation marks omitted).
    Two prescriptions of Arizona’s Constitution would ren­
    der the Legislature’s passage of a competing plan and
    submission of that plan to the Secretary of State unavail­
    ing. Indeed, those actions would directly and immediately
    conflict with the regime Arizona’s Constitution establishes.
    Cf. Sporhase v. Nebraska ex rel. Douglas, 
    458 U.S. 941
    , 944, n. 2 (1982) (failure to apply for permit which
    “would not have been granted” under existing law did not
    deprive plaintiffs of standing to challenge permitting
    regime). First, the Arizona Constitution instructs that the
    Legislature “shall not have the power to adopt any meas­
    ure that supersedes [an initiative], in whole or in part, . . .
    unless the superseding measure furthers the purposes” of
    the initiative. Art. IV, pt. 1, §1(14). Any redistricting map
    passed by the Legislature in an effort to supersede the
    AIRC’s map surely would not “furthe[r] the purposes” of
    Proposition 106. Second, once the AIRC certifies its redis­
    tricting plan to the Secretary of State, Arizona’s Constitu­
    tion requires the Secretary to implement that plan and no
    other. See Art. IV, pt. 2, §1(17); Arizona Minority Coali-
    tion for Fair Redistricting v. Arizona Independent Redis-

    121 P.3d 843
    , 857
    (App. 2005) (per curiam) (“Once the Commission certifies
    [its] maps, the secretary of state must use them in con­
    ducting the next election.”). To establish standing, the
    Legislature need not violate the Arizona Constitution and
    show that the Secretary of State would similarly disregard
    the State’s fundamental instrument of government.
    Raines v. Byrd, 
    521 U.S. 811
    (1997), does not aid
    AIRC’s argument that there is no standing here. In
    Raines, this Court held that six individual Members of
    Congress lacked standing to challenge the Line Item Veto
    Act. 
    Id., at 813–814,
    829–830 (holding specifically and
    only that “individual members of Congress [lack] Article
    III standing”). The Act, which gave the President author-
    ity to cancel certain spending and tax benefit measures
    after signing them into law, allegedly diluted the efficacy
    of the Congressmembers’ votes. 
    Id., at 815–817.
    The
    “institutional injury” at issue, we reasoned, scarcely ze­
    roed in on any individual Member. 
    Id., at 821.
    “[W]idely
    dispersed,” the alleged injury “necessarily [impacted] all
    Members of Congress and both Houses . . . equally.” 
    Id., at 829,
    821. None of the plaintiffs, therefore, could tena­
    bly claim a “personal stake” in the suit. 
    Id., at 830.
       In concluding that the individual Members lacked
    standing, the Court “attach[ed] some importance to the
    fact that [the Raines plaintiffs had] not been authorized to
    represent their respective Houses of Congress.” 
    Id., at 829.
    “[I]ndeed,” the Court observed, “both houses actively
    oppose[d] their suit.” 
    Ibid. Having failed to
    prevail in
    their own Houses, the suitors could not repair to the Judi­
    ciary to complain. The Arizona Legislature, in contrast, is
    an institutional plaintiff asserting an institutional injury,
    and it commenced this action after authorizing votes in
    both of its chambers, App. 26–27, 46. That “different . . .
    
    circumstanc[e],” 521 U.S., at 830

    Closer to the mark is this Court’s decision in Coleman v.
    Miller, 
    307 U.S. 433
    (1939). There, plaintiffs were 20 (of
    40) Kansas State Senators, whose votes “would have been
    sufficient to defeat [a] resolution ratifying [a] proposed
    [federal] constitutional amendment.” 
    Id., at 446.11

    10Massachusetts    v. Mellon, 
    262 U.S. 447
    (1923), featured in JUSTICE
    SCALIA’s dissent, post, at 4, bears little resemblance to this case. There,
    the Court unanimously found that Massachusetts lacked standing to
    sue the Secretary of the Treasury on a claim that a federal grant
    program exceeded Congress’ Article I powers and thus violated the
    Tenth Amendment. 
    Id., at 480.
    If suing on its own behalf, the Court
    reasoned, Massachusetts’ claim involved no “quasi-sovereign rights
    actually invaded or threatened.” 
    Id., at 485.
    As parens patriae, the
    Court stated: “[I]t is no part of [Massachusetts’] duty or power to
    enforce [its citizens’] rights in respect of their relations with the Federal
    Government. In that field it is the United States, and not the State,
    which represents them as parens patriae.” 
    Id., at 485–486.
    As astutely
    observed, moreover: “The cases on the standing of states to sue the
    federal government seem to depend on the kind of claim that the state
    advances. The decisions . . . are hard to reconcile.” R. Fallon, J. Man­

    Ibid. Coleman, as we
    later explained in Raines,
    stood “for the proposition that legislators whose votes
    would have been sufficient to defeat (or enact) a specific
    legislative Act have standing to sue if that legislative
    action goes into effect (or does not go into effect), on the
    ground that their votes have been completely 
    nullified.” 521 U.S., at 823
    .12 Our conclusion that the Arizona Legis­
    lature has standing fits that bill. Proposition 106, to-
    gether with the Arizona Constitution’s ban on efforts to un­
    dermine the purposes of an initiative, 
    see supra, at 11
    ,
    would “completely nullif[y]” any vote by the Legislature,
    now or “in the future,” purporting to adopt a redistricting
    plan.

    Congress has standing to bring a suit against the President. There is
    no federal analogue to Arizona’s initiative power, and a suit between
    Congress and the President would raise separation-of-powers concerns
    absent here. The Court’s standing analysis, we have noted, has been
    “especially rigorous when reaching the merits of the dispute would force

    III
    On the merits, we instructed the parties to address this
    question: Do the Elections Clause of the United States
    Constitution and 
    2 U.S. C
    . §2a(c) permit Arizona’s use of
    a commission to adopt congressional districts? The Elec­
    tions Clause is set out at the start of this 
    opinion, supra, at 2
    . Section 2a(c) provides:
    “Until a State is redistricted in the manner pro­
    vided by the law thereof after any apportionment, the
    Representatives to which such State is entitled under
    such apportionment shall be elected in the following
    manner: [setting out five federally prescribed redis­
    tricting procedures].”
    Before focusing directly on the statute and constitutional
    prescriptions in point, we summarize this Court’s prece­
    dent relating to appropriate state decisionmakers for
    redistricting purposes. Three decisions compose the rele­
    vant case law: Ohio ex rel. Davis v. Hildebrant, 
    241 U.S. 565
    (1916); Hawke v. Smith (No. 1), 
    253 U.S. 221
    (1920);
    and Smiley v. Holm, 
    285 U.S. 355
    (1932).
    A
    Davis v. Hildebrant involved an amendment to the
    Constitution of Ohio vesting in the people the right, exer­
    cisable by referendum, to approve or disapprove by popu­
    lar vote any law enacted by the State’s legislature. A 1915

    He forgets that the party invoking federal-court jurisdiction in this
    case, and inviting our review, is the Arizona State Legislature.
    15 JUSTICE THOMAS, on the way to deciding that the Arizona Legisla­
    ture lacks standing, first addresses the merits. In so doing, he over­
    looks that, in the cases he features, it was entirely immaterial whether
    the law involved was adopted by a representative body or by the people,
    through exercise of the initiative.
    16       ARIZONA STATE LEGISLATURE v. ARIZONA
    INDEPENDENT REDISTRICTING COMM’N
    Opinion of the Court
    elections had been submitted to a popular vote, resulting
    in disapproval of the legislature’s measure. State election
    officials asked the State’s Supreme Court to declare the
    referendum void. That court rejected the request, holding
    that the referendum authorized by Ohio’s Constitution,
    “was a part of the legislative power of the State,” and
    “nothing in [federal statutory law] or in [the Elections
    Clause] operated to the 
    contrary.” 241 U.S., at 567
    . This
    Court affirmed the Ohio Supreme Court’s judgment. In
    upholding the state court’s decision, we recognized that
    the referendum was “part of the legislative power” in Ohio,
    ibid., legitimately exercised by the people to disapprove
    the legislation creating congressional districts. For redis­
    tricting purposes, Hildebrant thus established, “the Leg-
    islature” did not mean the representative body alone.
    Rather, the word encompassed a veto power lodged in the
    people. See 
    id., at 569
    (Elections Clause does not bar
    “treating the referendum as part of the legislative power
    for the purpose of apportionment, where so ordained by
    the state constitutions and laws”).
    Hawke v. Smith involved the Eighteenth Amendment to
    the Federal Constitution. Ohio’s Legislature had ratified
    the Amendment, and a referendum on that ratification
    was at issue. Reversing the Ohio Supreme Court’s deci­
    sion upholding the referendum, we held that “ratification
    by a State of a constitutional amendment is not an act of
    legislation within the proper sense of the 
    word.” 253 U.S., at 229
    . Instead, Article V governing ratification had
    lodged in “the legislatures of three-fourths of the several
    States” sole authority to assent to a proposed amendment.
    
    Id., at 226.
    The Court contrasted the ratifying function,
    exercisable exclusively by a State’s legislature, with “the
    ordinary business of legislation.” 
    Id., at 229.
    Davis v.
    Hildebrant, the Court explained, involved the enactment
    of legislation, i.e., a redistricting plan, and properly held
    that “the referendum [was] part of the legislative author-
    Cite as: 576 U. S. ____ (2015)                17
    Opinion of the Court
    ity of the State for [that] 
    purpose.” 253 U.S., at 230
    .
    Smiley v. Holm raised the question whether legislation
    purporting to redistrict Minnesota for congressional elec­
    tions was subject to the Governor’s veto. The Minnesota
    Supreme Court had held that the Elections Clause placed
    redistricting authority exclusively in the hands of the
    State’s legislature, leaving no role for the Governor. We
    reversed that determination and held, for the purpose at
    hand, Minnesota’s legislative authority includes not just
    the two houses of the legislature; it includes, in addition, a
    make-or-break role for the Governor. In holding that the
    Governor’s veto counted, we distinguished instances in
    which the Constitution calls upon state legislatures to
    exercise a function other than lawmaking. State legisla­
    tures, we pointed out, performed an “electoral” function “in
    the choice of United States Senators under Article I, sec­
    tion 3, prior to the adoption of the Seventeenth Amend­
    ment,”16 a “ratifying” function for “proposed amendments
    to the Constitution under Article V,” as explained in
    Hawke v. Smith, and a “consenting” function “in relation
    to the acquisition of lands by the United States under
    Article I, section 8, paragraph 
    17.” 285 U.S., at 365
    –366.
    In contrast to those other functions, we observed, redis­
    tricting “involves lawmaking in its essential features and
    most important aspect.” 
    Id., at 366.
    Lawmaking, we
    further noted, ordinarily “must be in accordance with the
    method which the State has prescribed for legislative
    enactments.” 
    Id., at 367.
    In Minnesota, the State’s Con­
    stitution had made the Governor “part of the legislative
    process.” 
    Id., at 369.
    And the Elections Clause, we ex­
    plained, respected the State’s choice to include the Gover­
    nor in that process, although the Governor could play no
    part when the Constitution assigned to “the Legislature” a

    ratifying, electoral, or consenting function. Nothing in the
    Elections Clause, we said, “attempt[ed] to endow the
    legislature of the State with power to enact laws in any
    manner other than that in which the constitution of the
    State ha[d] provided that laws shall be enacted.” 
    Id., at 368.
       THE CHIEF JUSTICE, in dissent, features, indeed trum­
    pets repeatedly, the pre-Seventeenth Amendment regime
    in which Senators were “chosen [in each State] by the
    Legislature thereof.” Art. I, §3; see post, at 1, 8–9, 19. If
    we are right, he asks, why did popular election proponents
    resort to the amending process instead of simply interpret­
    ing “the Legislature” to mean “the people”? Post, at 1.
    Smiley, as just indicated, answers that question. Article I,
    §3, gave state legislatures “a function different from that
    of 
    lawgiver,” 285 U.S., at 365
    ; it made each of them “an
    electoral body” charged to perform that function to the
    exclusion of other participants, 
    ibid. So too, of
    the ratify­
    ing function. As we explained in Hawke, “the power to
    legislate in the enactment of the laws of a State is derived
    from the people of the 
    State.” 253 U.S., at 230
    . Ratifica­
    tion, however, “has its source in the Federal Constitution”
    and is not “an act of legislation within the proper sense of
    the word.” 
    Id., at 229–230.
       Constantly resisted by THE CHIEF JUSTICE, but well
    understood in opinions that speak for the Court: “[T]he
    meaning of the word ‘legislature,’ used several times in the
    Federal Constitution, differs according to the connection in
    which it is employed, depend[ent] upon the character of
    the function which that body in each instance is called
    upon to exercise.” Atlantic Cleaners & Dyers, Inc. v. United

    dum and the Governor’s veto in the context of regulating
    congressional elections. Hildebrant,

    In sum, our precedent teaches that redistricting is a
    legislative function, to be performed in accordance with
    the State’s prescriptions for lawmaking, which may in­
    clude the referendum and the Governor’s veto. The exer­
    cise of the initiative, we acknowledge, was not at issue in
    our prior decisions. But as developed below, we see no
    constitutional barrier to a State’s empowerment of its
    people by embracing that form of lawmaking.

    17 The list of constitutional provisions in which the word “legislature”
    appears, appended to THE CHIEF JUSTICE’s opinion, post, at 28–32, is
    illustrative of the variety of functions state legislatures can be called
    upon to exercise. For example, Art. I, §2, cl. 1, superseded by the
    Seventeenth Amendment, assigned an “electoral” function. See 
    Smiley, 285 U.S., at 365
    . Article I, §3, cl. 2, assigns an “appointive” function.
    Article I, §8, cl. 17, assigns a “consenting” function, see 
    Smiley, 285 U.S., at 366
    , as does Art. IV, §3, cl. 1. “[R]atifying” functions are
    assigned in Art. V, Amdt. 18, §3, Amdt. 20, §6, and Amdt. 22, §2. See
    
    Hawke, 253 U.S., at 229
    . But Art. I, §4, cl. 1, unquestionably calls for
    the exercise of lawmaking authority. That authority can be carried out
    by a representative body, but if a State so chooses, legislative authority
    can also be lodged in the people themselves. See infra, at 24–35.

    20         ARIZONA STATE LEGISLATURE v. ARIZONA
    INDEPENDENT REDISTRICTING COMM’N
    Opinion of the Court
    quired to follow federally prescribed procedures for redis­
    tricting unless “the legislature” of the State drew district
    lines. E.g., Act of July 14, 1862, ch. 170, 12 Stat. 572; Act
    of Jan. 16, 1901, ch. 93, §4, 31 Stat. 734. In drafting the
    1911 Act, Congress focused on the fact that several States
    had supplemented the representative legislature mode of
    lawmaking with a direct lawmaking role for the people,
    through the processes of initiative (positive legislation by
    the electorate) and referendum (approval or disapproval of
    legislation by the electorate). 47 Cong. Rec. 3508 (state­
    ment of Sen. Burton); 
    see supra, at 3
    –5. To accommodate
    that development, the 1911 Act eliminated the statutory
    reference to redistricting by the state “legislature” and
    instead directed that, if a State’s apportionment of Repre­
    sentatives increased, the State should use the Act’s de­
    fault procedures for redistricting “until such State shall be
    redistricted in the manner provided by the laws thereof.”
    Ch. 5, §4, 37 Stat. 14 (emphasis added).19
    Some Members of Congress questioned whether the
    language change was needed. In their view, existing
    apportionment legislation (referring to redistricting by a
    State’s “legislature”) “suffic[ed] to allow, whatever the law
    of the State may be, the people of that State to control
    [redistricting].” 47 Cong. Rec. 3507 (statement of Sen.
    ——————
    19 The 1911 Act also required States to comply with certain federally
    prescribed districting rules—namely, that Representatives be elected
    “by districts composed of a contiguous and compact territory, and
    containing as nearly as practicable an equal number of inhabitants,”
    and that the districts “be equal to the number of Representatives to
    which [the] State may be entitled in Congress, no district electing more
    than one Representative.” Act of Aug. 8, 1911, ch. 5, §§3–4, 37 Stat. 14.
    When a State’s apportionment of Representatives remained constant,
    the Act directed the State to continue using its pre-existing districts
    “until [the] State shall be redistricted as herein prescribed.” See §4,
    
    ibid. The 1911 Act
    did not address redistricting in the event a State’s
    apportionment of Representatives decreased, likely because no State
    faced a decrease following the 1910 census.

    Shively); cf. Shiel v. Thayer, Bartlett Contested Election
    Cases, H. R. Misc. Doc. No. 57, 38th Cong., 2d Sess., 351
    (1861) (view of House Committee of Elections Member
    Dawes that Art. I, §4’s reference to “the Legislature”
    meant simply the “constituted authorities, through whom
    [the State] choose[s] to speak,” prime among them, the
    State’s Constitution, “which rises above . . . all legislative
    action”). Others anticipated that retaining the reference
    to “the legislature” would “condem[n] . . . any [redistrict­
    ing] legislation by referendum or by initiative.” 47 Cong.
    Rec. 3436 (statement of Sen. Burton). In any event, pro­
    ponents of the change maintained, “[i]n view of the very
    serious evils arising from gerrymanders,” Congress should
    not “take any chances in [the] matter.” 
    Id., at 3508
    (same). “[D]ue respect to the rights, to the established
    methods, and to the laws of the respective States,” they
    urged, required Congress “to allow them to establish
    congressional districts in whatever way they may have
    provided by their constitution and by their statutes.” 
    Id., at 3436;
    see 
    id., at 3508
    (statement of Sen. Works).
    As this Court observed in Hildebrant, “the legislative
    history of th[e] [1911 Act] leaves no room for doubt [about
    why] the prior words were stricken out and the new words
    
    inserted.” 241 U.S., at 568
    . The change was made to
    safeguard to “each State full authority to employ in the
    creation of congressional districts its own laws and regula­
    tions.” 47 Cong. Rec. 3437 (statement of Sen. Burton).
    The 1911 Act, in short, left the question of redistricting “to
    the laws and methods of the States. If they include initia­
    tive, it is included.” 
    Id., at 3508.
       While the 1911 Act applied only to reapportionment
    following the 1910 census, see Wood v. Broom, 
    287 U.S. 1
    ,
    6–7 (1932), Congress used virtually identical language
    when it enacted §2a(c) in 1941. See Act of Nov. 15, 1941,
    ch. 470, 55 Stat. 761–762. Section 2a(c) sets forth con­
    gressional-redistricting procedures operative only if the
    22          ARIZONA STATE LEGISLATURE v. ARIZONA
    INDEPENDENT REDISTRICTING COMM’N
    Opinion of the Court
    State, “after any apportionment,” had not redistricted “in
    the manner provided by the law thereof.” The 1941 provi­
    sion, like the 1911 Act, thus accorded full respect to the
    redistricting procedures adopted by the States. So long as
    a State has “redistricted in the manner provided by the
    law thereof ”—as Arizona did by utilizing the independent
    commission procedure called for by its Constitution—the
    resulting redistricting plan becomes the presumptively
    governing map.20
    The Arizona Legislature characterizes §2a(c) as an
    “obscure provision, narrowed by subsequent developments
    to the brink of irrelevance.” Brief for Appellant 56. True,
    four of the five default redistricting procedures—operative
    only when a State is not “redistricted in the manner pro­
    vided by [state] law”—had “become (because of postenact­
    ment decisions of this Court) in virtually all situations
    plainly unconstitutional.” Branch v. Smith, 
    538 U.S. 254
    ,
    273–274 (2003) (plurality opinion). Concretely, the default
    procedures specified in §2a(c)(1)–(4) contemplate that a
    State would continue to use pre-existing districts following
    a new census. The one-person, one-vote principle an­
    nounced in Wesberry v. Sanders, 
    376 U.S. 1
    (1964), how­
    ever, would bar those procedures, except in the “unlikely”
    event that “the decennial census makes no districting
    change constitutionally necessary,” 
    Branch, 538 U.S., at 273
    (plurality opinion).
    Constitutional infirmity in §2a(c)(1)–(4)’s default proce­
    dures, however, does not bear on the question whether a
    State has been “redistricted in the manner provided by
    [state] law.”21 As just observed, Congress expressly di­
    ——————
    20 Because a State is required to comply with the Federal Constitu­
    tion, the Voting Rights Act, and other federal laws when it draws and
    implements its district map, nothing in §2a(c) affects a challenge to a
    state district map on the ground that it violates one or more of those
    federal requirements.

    538 U.S. 254

    Opinion of the Court
    rected that when a State has been “redistricted in the
    manner provided by [state] law”—whether by the legisla­
    ture, court decree (see 
    id., at 274),
    or a commission estab­
    lished by the people’s exercise of the initiative—the result­
    ing districts are the ones that presumptively will be used
    to elect Representatives.22
    There can be no dispute that Congress itself may draw a
    State’s congressional-district boundaries. See 
    Vieth, 541 U.S., at 275
    (plurality opinion) (stating that the Elections
    Clause “permit[s] Congress to ‘make or alter’ ” the “dis­
    tricts for federal elections”). The Arizona Legislature
    urges that the first part of the Elections Clause, vesting
    power to regulate congressional elections in State “Legis­
    lature[s],” precludes Congress from allowing a State to
    redistrict without the involvement of its representative
    body, even if Congress independently could enact the same
    redistricting plan under its plenary authority to “make or
    alter” the State’s plan. See Brief for Appellant 56–57;
    Reply Brief 17. In other words, the Arizona Legislature
    regards §2a(c) as a futile exercise. The Congresses that
    passed §2a(c) and its forerunner, the 1911 Act, did not
    share that wooden interpretation of the Clause, nor do we.
    Any uncertainty about the import of §2a(c), however, is
    resolved by our holding that the Elections Clause permits
    regulation of congressional elections by initiative, see
    infra, at 24–35, leaving no arguable conflict between
    §2a(c) and the first part of the Clause.
    ——————
    ered the question whether §2a(c) had been repealed by implication and
    stated, “where what it prescribes is constitutional,” the provision
    “continues to apply.”
    22 THE CHIEF JUSTICE, in dissent, insists that §2a(c) and its precursor,
    the 1911 Act, have nothing to do with this case. Post, at 20–21, 23.
    Undeniably, however, it was the very purpose of the measures to
    recognize the legislative authority each State has to determine its own
    redistricting regime.
    24         ARIZONA STATE LEGISLATURE v. ARIZONA
    INDEPENDENT REDISTRICTING COMM’N
    Opinion of the Court
    C
    In accord with the District Court, 
    see supra, at 9
    , we
    hold that the Elections Clause permits the people of Ari­
    zona to provide for redistricting by independent commis­
    sion. To restate the key question in this case, the issue
    centrally debated by the parties: Absent congressional
    authorization, does the Elections Clause preclude the
    people of Arizona from creating a commission operating
    independently of the state legislature to establish congres­
    sional districts? The history and purpose of the Clause
    weigh heavily against such preclusion, as does the animat­
    ing principle of our Constitution that the people them­
    selves are the originating source of all the powers of
    government.
    We note, preliminarily, that dictionaries, even those in
    circulation during the founding era, capaciously define the
    word “legislature.” Samuel Johnson defined “legislature”
    simply as “[t]he power that makes laws.” 2 A Dictionary
    of the English Language (1st ed. 1755); 
    ibid. (6th ed. 1785);
    ibid. (10th ed. 1792); 
    ibid. (12th ed. 1802). 
    Thomas
    Sheridan’s dictionary defined “legislature” exactly as Dr.
    Johnson did: “The power that makes laws.” 2 A Complete
    Dictionary of the English Language (4th ed. 1797). Noah
    Webster defined the term precisely that way as well.
    Compendious Dictionary of the English Language 174
    (1806). And Nathan Bailey similarly defined “legislature”
    as “the Authority of making Laws, or Power which makes
    them.” An Universal Etymological English Dictionary
    (20th ed. 1763).23

    23 Illustrative of an embracive comprehension of the word “legisla­
    ture,” Charles Pinckney explained at South Carolina’s ratifying conven­
    tion that America is “[a] republic, where the people at large, either
    collectively or by representation, form the legislature.” 4 Debates on
    the Federal Constitution 328 (J. Elliot 2d ed. 1863). Participants in the
    debates over the Elections Clause used the word “legislature” inter­
    changeably with “state” and “state government.” See Brief for Brennan

    Opinion of the Court
    As to the “power that makes laws” in Arizona, initia­
    tives adopted by the voters legislate for the State just as
    measures passed by the representative body do. See Ariz.
    Const., Art. IV, pt. 1, §1 (“The legislative authority of the
    state shall be vested in the legislature, consisting of a
    senate and a house of representatives, but the people
    reserve the power to propose laws and amendments to the
    constitution and to enact or reject such laws and amend­
    ments at the polls, independently of the legislature.”). See
    also Eastlake v. Forest City Enterprises, Inc., 
    426 U.S. 668
    , 672 (1976) (“In establishing legislative bodies, the
    people can reserve to themselves power to deal directly
    with matters which might otherwise be assigned to the
    legislature.”). As well in Arizona, the people may delegate
    their legislative authority over redistricting to an inde­
    pendent commission just as the representative body may
    choose to do. See Tr. of Oral Arg. 15–16 (answering the
    Court’s question, may the Arizona Legislature itself estab­
    lish a commission to attend to redistricting, counsel for
    appellant responded yes, state legislatures may delegate
    their authority to a commission, subject to their preroga­
    tive to reclaim the authority for themselves).
    1
    The dominant purpose of the Elections Clause, the
    historical record bears out, was to empower Congress to
    override state election rules, not to restrict the way States
    enact legislation. As this Court explained in Arizona v.
    Inter Tribal Council of Ariz., Inc., 
    570 U.S. 1

    Clause “was the Framers’ insurance against the possibility

    26       ARIZONA STATE LEGISLATURE v. ARIZONA
    INDEPENDENT REDISTRICTING COMM’N
    Opinion of the Court
    The Clause was also intended to act as a safeguard
    against manipulation of electoral rules by politicians and
    factions in the States to entrench themselves or place their
    interests over those of the electorate. As Madison urged,
    without the Elections Clause, “[w]henever the State Legis­
    latures had a favorite measure to carry, they would take
    care so to mould their regulations as to favor the candi­
    dates they wished to succeed.” 2 Records of the Federal
    Convention 241 (M. Farrand rev. 1966). Madison spoke in
    response to a motion by South Carolina’s delegates to
    strike out the federal power. Those delegates so moved
    because South Carolina’s coastal elite had malapportioned
    their legislature, and wanted to retain the ability to do so.
    See J. Rakove, Original Meanings: Politics and Ideas in
    the Making of the Constitution 223–224 (1996). The
    problem Madison identified has hardly lessened over time.
    Conflict of interest is inherent when “legislators dra[w]
    district lines that they ultimately have to run in.” Cain,
    121 Yale L. J., at 1817.
    Arguments in support of congressional control under the
    Elections Clause were reiterated in the public debate over
    ratification. Theophilus Parsons, a delegate at the Massa­
    chusetts ratifying convention, warned that “when faction
    and party spirit run high,” a legislature might take actions
    like “mak[ing] an unequal and partial division of the
    states into districts for the election of representatives.”
    Debate in Massachusetts Ratifying Convention (16–17, 21
    Jan. 1788), in 2 The Founders’ Constitution 256 (P. Kur­
    land & R. Lerner eds. 1987). Timothy Pickering of Massa­
    chusetts similarly urged that the Clause was necessary
    because “the State governments may abuse their power,
    and regulate . . . elections in such manner as would be
    highly inconvenient to the people.” Letter to Charles
    Tillinghast (24 Dec. 1787), in 
    id., at 253.
    He described the
    Clause as a way to “ensure to the people their rights of
    election.”

    Opinion of the Court
    While attention focused on potential abuses by state-
    level politicians, and the consequent need for congres-
    sional oversight, the legislative processes by which the States
    could exercise their initiating role in regulating congres­
    sional elections occasioned no debate. That is hardly
    surprising. Recall that when the Constitution was com­
    posed in Philadelphia and later ratified, the people’s legis­
    lative prerogatives—the initiative and the referendum—
    were not yet in our democracy’s arsenal. 
    See supra, at 3
    –
    5. The Elections Clause, however, is not reasonably read
    to disarm States from adopting modes of legislation that
    place the lead rein in the people’s hands.24
    2
    The Arizona Legislature maintains that, by specifying
    “the Legislature thereof,” the Elections Clause renders the
    State’s representative body the sole “component of state
    government authorized to prescribe . . . regulations . . . for
    congressional redistricting.” Brief for Appellant 30. THE
    CHIEF JUSTICE, in dissent, agrees. But it is characteristic
    of our federal system that States retain autonomy to
    establish their own governmental processes. See Alden v.
    Maine,

    We resist reading the Elections Clause to single out
    federal elections as the one area in which States may not
    use citizen initiatives as an alternative legislative process.
    Nothing in that Clause instructs, nor has this Court ever
    held, that a state legislature may prescribe regulations on
    the time, place, and manner of holding federal elections in
    defiance of provisions of the State’s constitution. See

    Oregon’s Constitution prevailed over any conflicting leg-
    islative measure setting the date for a congressional
    election).
    THE CHIEF JUSTICE, in dissent, maintains that, under
    the Elections Clause, the state legislature can trump any
    initiative-introduced constitutional provision regulating
    federal elections. He extracts support for this position
    from Baldwin v. Trowbridge, 2 Bartlett Contested Election
    Cases, H. R. Misc. Doc. No. 152, 41st Cong., 2d Sess., 46–
    47 (1866). See post, at 15–16. There, Michigan voters had
    amended the State Constitution to require votes to be cast
    within a resident’s township or ward. The Michigan Leg­
    islature, however, passed a law permitting soldiers to vote
    in other locations. One candidate would win if the State
    Constitution’s requirement controlled; his opponent would
    prevail under the Michigan Legislature’s prescription.
    The House Elections Committee, in a divided vote, ruled
    that, under the Elections Clause, the Michigan Legisla­
    ture had the paramount power.
    As the minority report in Baldwin pointed out, however,
    the Supreme Court of Michigan had reached the opposite
    conclusion, holding, as courts generally do, that state
    legislation in direct conflict with the State’s constitution is
    void. Baldwin, H. R. Misc. Doc. No. 152, at 50. The
    Baldwin majority’s ruling, furthermore, appears in ten­
    sion with the Election Committee’s unanimous decision in
    Shiel just five years earlier. (The Committee, we repeat,
    “ha[d] no doubt that the constitution of the State ha[d]
    fixed, beyond the control of the legislature, the time for
    holding [a congressional] election.” Shiel, H. R. Misc. Doc.
    No. 57, at 351.) Finally, it was perhaps not entirely acci­
    dental that the candidate the Committee declared winner
    in Baldwin belonged to the same political party as all but
    one member of the House Committee majority responsible
    for the decision. See U. S. House of Representatives Con­

    We add, furthermore, that the Arizona Legislature does
    not question, nor could it, employment of the initiative to
    control state and local elections. In considering whether
    Article I, §4, really says “No” to similar control of federal
    elections, we have looked to, and borrow from, Alexander
    Hamilton’s counsel: “[I]t would have been hardly advisable
    . . . to establish, as a fundamental point, what would
    deprive several States of the convenience of having the
    elections for their own governments and for the national
    government” held at the same times and places, and in the
    same manner. The Federalist No. 61, at 374. The Elec­
    tions Clause is not sensibly read to subject States to that
    deprivation.25

    The Framers may not have imagined the modern initia­
    tive process in which the people of a State exercise legisla­
    tive power coextensive with the authority of an institu­
    tional legislature. But the invention of the initiative was
    in full harmony with the Constitution’s conception of the
    people as the font of governmental power. As Madison put
    it: “The genius of republican liberty seems to demand . . .
    not only that all power should be derived from the people,
    ——————
    25 A State may choose to regulate state and national elections differ­
    ently, which is its prerogative under the Clause. E.g., Ind. Code §3–3–

    lative districts).

    but that those intrusted with it should be kept in depend­
    ence on the people.” 
    Id., No. 37,

    The people’s ultimate sovereignty had been expressed by
    John Locke in 1690, a near century before the Constitu­
    tion’s formation:
    “[T]he Legislative being only a Fiduciary Power to act
    for certain ends, there remains still in the People a
    Supream Power to remove or alter the Legislative,
    when they find the Legislative act contrary to the
    trust reposed in them. For all Power given with trust
    for the attaining an end, being limited by that end,
    whenever that end is manifestly neglected, or op­
    posed, the trust must necessarily be forfeited, and the
    Power devolve into the hands of those that gave it,
    who may place it anew where they shall think best for
    their safety and security.” Two Treatises of Govern­
    ment §149, p. 385 (P. Laslett ed. 1964).
    Our Declaration of Independence, ¶2, drew from Locke in
    stating: “Governments are instituted among Men, deriving
    their just powers from the consent of the governed.” And
    our fundamental instrument of government derives its
    authority from “We the People.” U. S. Const., Preamble.
    As this Court stated, quoting Hamilton: “[T]he true prin­
    ciple of a republic is, that the people should choose whom
    they please to govern them.” Powell v. McCormack, 
    395 U.S. 486
    , 540–541 (1969) (quoting 2 Debates on the Fed­
    eral Constitution 257 (J. Elliot ed. 1876)). In this light, it
    would be perverse to interpret the term “Legislature” in
    the Elections Clause so as to exclude lawmaking by the
    people, particularly where such lawmaking is intended to
    check legislators’ ability to choose the district lines they
    run in, thereby advancing the prospect that Members of
    Congress will in fact be “chosen . . . by the People of the
    several States,” Art. I, §2. See Cain, 121 Yale L. J., at
    1817.
    32       ARIZONA STATE LEGISLATURE v. ARIZONA
    INDEPENDENT REDISTRICTING COMM’N
    Opinion of the Court
    THE CHIEF JUSTICE, in dissent, suggests that independ­
    ent commissions established by initiative are a high-
    minded experiment that has failed. Post, at 26–27. For
    this assessment, THE CHIEF JUSTICE cites a three-judge
    Federal District Court opinion, Harris v. Arizona Inde-
    pendent Redistricting Comm’n, 
    993 F. Supp. 2d 1042
    (Ariz.
    2014). That opinion, he asserts, “detail[s] the partisanship
    that has affected the Commission.” Post, at 26. No careful
    reader could so conclude.
    The report of the decision in Harris comprises a per
    curiam opinion, an opinion concurring in the judgment by
    Judge Silver, and a dissenting opinion by Judge Wake.
    The per curiam opinion found “in favor of the Commis­
    
    sion.” 993 F. Supp. 2d, at 1080
    . Deviations from the one-
    person, one-vote principle, the per curiam opinion ex­
    plained at length, were “small” and, in the main, could not
    be attributed to partisanship. 
    Ibid. While partisanship “may
    have played some role,” the per curiam opinion
    stated, deviations were “predominantly a result of the
    Commission’s good-faith efforts to achieve preclearance
    under the Voting Rights Act.” 
    Id., at 1060.
    Judge Silver,
    although she joined the per curiam opinion, made clear at
    the very outset of that opinion her finding that “partisan­
    ship did not play a role.” 
    Id., at 1046,
    n. 1. In her concur­
    ring opinion, she repeated her finding that the evidence
    did not show partisanship at work, 
    id., at 1087;
    instead,
    she found, the evidence “[was] overwhelming [that] the
    final map was a product of the commissioners’s considera­
    tion of appropriate redistricting criteria.” 
    Id., at 1088.
    To
    describe Harris as a decision criticizing the Commission
    for pervasive partisanship, post, at 26, THE CHIEF JUSTICE
    could rely only upon the dissenting opinion, which ex­
    pressed views the majority roundly rejected.
    Independent redistricting commissions, it is true, “have
    not eliminated the inevitable partisan suspicions associ-
    ated with political line-drawing.” Cain, 121 Yale L. J., at
    Cite as: 576 U. S. ____ (2015)           33
    Opinion of the Court
    1808. But “they have succeeded to a great degree [in
    limiting the conflict of interest implicit in legislative con­
    trol over redistricting].” 
    Ibid. They thus impede
    legisla­
    tors from choosing their voters instead of facilitating the
    voters’ choice of their representatives.
    4
    Banning lawmaking by initiative to direct a State’s
    method of apportioning congressional districts would do
    more than stymie attempts to curb partisan gerrymander­
    ing, by which the majority in the legislature draws district
    lines to their party’s advantage. It would also cast doubt
    on numerous other election laws adopted by the initiative
    method of legislating.
    The people, in several States, functioning as the law­
    making body for the purpose at hand, have used the initia­
    tive to install a host of regulations governing the “Times,
    Places and Manner” of holding federal elections. Art. I, §4.
    For example, the people of California provided for perma­
    nent voter registration, specifying that “no amendment by
    the Legislature shall provide for a general biennial or
    other periodic reregistration of voters.” Cal. Elec. Code
    Ann. §2123 (West 2003). The people of Ohio banned bal­
    lots providing for straight-ticket voting along party lines.
    Ohio Const., Art. V, §2a. The people of Oregon shortened
    the deadline for voter registration to 20 days prior to an
    election. Ore. Const., Art. II, §2. None of those measures
    permit the state legislatures to override the people’s pre­
    scriptions. The Arizona Legislature’s theory—that the
    lead role in regulating federal elections cannot be wrested
    from “the Legislature,” and vested in commissions initiated
    by the people—would endanger all of them.
    The list of endangered state elections laws, were we to
    sustain the position of the Arizona Legislature, would not
    stop with popular initiatives. Almost all state constitu­
    tions were adopted by conventions and ratified by voters

    Opinion of the Court
    at the ballot box, without involvement or approval by “the
    Legislature.”26 Core aspects of the electoral process regu­
    lated by state constitutions include voting by “ballot” or
    “secret ballot,”27 voter registration,28 absentee voting,29
    vote counting,30 and victory thresholds.31 Again, the
    States’ legislatures had no hand in making these laws and
    may not alter or amend them.
    The importance of direct democracy as a means to con­
    trol election regulations extends beyond the particular
    statutes and constitutional provisions installed by the
    people rather than the States’ legislatures. The very
    prospect of lawmaking by the people may influence the
    legislature when it considers (or fails to consider) election-
    related measures. See Persily & Anderson, Regulating
    Democracy Through Democracy: The Use of Direct Legis­

    26 See App. to Brief for Appellees 11a–29a (collecting state constitu­

    tions are not simply past history predating the first election of state

    constitutional conventions in 1992. J. Dinan, The American State
    Constitutional Tradition 8–9 (2006) (Table 1–1). The State’s provision
    for voting by “secret ballot” may be traced to the constitutional conven­
    tion held by the State in 1812, see La. Const., Art. VI, §13, but was
    most recently reenacted at the State’s 1974 constitutional convention,
    see Art. XI, §2.

    Invoking the Elections Clause, the Arizona Legislature
    instituted this lawsuit to disempower the State’s voters
    from serving as the legislative power for redistricting
    purposes. But the Clause surely was not adopted to di­
    minish a State’s authority to determine its own lawmak­
    ing processes. Article I, §4, stems from a different view.
    Both parts of the Elections Clause are in line with the
    fundamental premise that all political power flows from
    the people. McCulloch v. Maryland, 
    4 Wheat. 316
    , 404–
    405 (1819). So comprehended, the Clause doubly empow­
    ers the people. They may control the State’s lawmaking
    processes in the first instance, as Arizona voters have
    done, and they may seek Congress’ correction of regula­
    tions prescribed by state legislatures.
    The people of Arizona turned to the initiative to curb the
    practice of gerrymandering and, thereby, to ensure that
    Members of Congress would have “an habitual recollection
    of their dependence on the people.” The Federalist No. 57,
    at 350 (J. Madison). In so acting, Arizona voters sought to
    restore “the core principle of republican government,”
    namely, “that the voters should choose their representa­
    tives, not the other way around.” Berman, Managing
    Gerrymandering, 83 Texas L. Rev. 781 (2005). The Elec­
    tions Clause does not hinder that endeavor.
    For the reasons stated, the judgment of the United
    States District Court for the District of Arizona is
    Affirmed.

    ARIZONA STATE LEGISLATURE, APPELLANT v.
    ARIZONA INDEPENDENT REDISTRICTING
    COMMISSION ET AL.
    ON APPEAL FROM THE UNITED STATES DISTRICT COURT FOR
    THE DISTRICT OF ARIZONA
    [June 29, 2015]
    CHIEF JUSTICE ROBERTS, with whom JUSTICE SCALIA,
    JUSTICE THOMAS, and JUSTICE ALITO join, dissenting.
    Just over a century ago, Arizona became the second
    State in the Union to ratify the Seventeenth Amendment.
    That Amendment transferred power to choose United
    States Senators from “the Legislature” of each State,
    Art. I, §3, to “the people thereof.” The Amendment re-
    sulted from an arduous, decades-long campaign in which
    reformers across the country worked hard to garner ap-
    proval from Congress and three-quarters of the States.
    What chumps! Didn’t they realize that all they had to
    do was interpret the constitutional term “the Legislature”
    to mean “the people”? The Court today performs just such
    a magic trick with the Elections Clause. Art. I, §4. That
    Clause vests congressional redistricting authority in “the
    Legislature” of each State. An Arizona ballot initiative
    transferred that authority from “the Legislature” to an
    “Independent Redistricting Commission.” The majority
    approves this deliberate constitutional evasion by doing
    what the proponents of the Seventeenth Amendment
    dared not: revising “the Legislature” to mean “the people.”
    The Court’s position has no basis in the text, structure,
    or history of the Constitution, and it contradicts prece-
    dents from both Congress and this Court. The Constitu-
    2         ARIZONA STATE LEGISLATURE v. ARIZONA
    INDEPENDENT REDISTRICTING COMM’N
    ROBERTS, C. J., dissenting
    tion contains seventeen provisions referring to the “Legis-
    lature” of a State, many of which cannot possibly be read
    to mean “the people.” See Appendix, infra. Indeed, several
    provisions expressly distinguish “the Legislature” from
    “the People.” See Art. I, §2; Amdt. 17. This Court has
    accordingly defined “the Legislature” in the Elections
    Clause as “the representative body which ma[kes] the laws
    of the people.” Smiley v. Holm, 
    285 U.S. 355
    , 365 (1932)
    (quoting Hawke v. Smith (No. 1), 
    253 U.S. 221
    , 227
    (1920); emphasis added).
    The majority largely ignores this evidence, relying
    instead on disconnected observations about direct democ-
    racy, a contorted interpretation of an irrelevant statute,
    and naked appeals to public policy. Nowhere does the
    majority explain how a constitutional provision that vests
    redistricting authority in “the Legislature” permits a State
    to wholly exclude “the Legislature” from redistricting.
    Arizona’s Commission might be a noble endeavor—
    although it does not seem so “independent” in practice—
    but the “fact that a given law or procedure is efficient,
    convenient, and useful . . . will not save it if it is contrary
    to the Constitution.” INS v. Chadha, 
    462 U.S. 919
    , 944
    (1983). No matter how concerned we may be about parti-
    sanship in redistricting, this Court has no power to ger-
    rymander the Constitution. I respectfully dissent.
    I
    The majority begins by discussing policy. I begin with
    the Constitution. The Elections Clause provides:
    “The Times, Places and Manner of holding Elections
    for Senators and Representatives, shall be prescribed
    in each State by the Legislature thereof; but the Con-
    gress may at any time by Law make or alter such
    Regulations, except as to the Places of chusing Sena-
    tors.” Art. I, §4, cl. 1.
    Cite as: 576 U. S. ____ (2015)             3
    ROBERTS, C. J., dissenting
    The Elections Clause both imposes a duty on States and
    assigns that duty to a particular state actor: In the ab-
    sence of a valid congressional directive to the contrary,
    States must draw district lines for their federal represent-
    atives. And that duty “shall” be carried out “in each State
    by the Legislature thereof.”
    In Arizona, however, redistricting is not carried out by
    the legislature. Instead, as the result of a ballot initiative,
    an unelected body called the Independent Redistricting
    Commission draws the lines. See ante, at 6–7. The key
    question in the case is whether the Commission can con-
    duct congressional districting consistent with the directive
    that such authority be exercised “by the Legislature.”
    The majority concedes that the unelected Commission is
    not “the Legislature” of Arizona. The Court contends
    instead that the people of Arizona as a whole constitute
    “the Legislature” for purposes of the Elections Clause, and
    that they may delegate the congressional districting au-
    thority conferred by that Clause to the Commission. Ante,
    at 25. The majority provides no support for the delegation
    part of its theory, and I am not sure whether the major-
    ity’s analysis is correct on that issue. But even giving the
    Court the benefit of the doubt in that regard, the Commis-
    sion is still unconstitutional. Both the Constitution and
    our cases make clear that “the Legislature” in the Elec-
    tions Clause is the representative body which makes the
    laws of the people.
    A
    The majority devotes much of its analysis to establish-
    ing that the people of Arizona may exercise lawmaking
    power under their State Constitution. See ante, at 5–6,
    25, 27–28. Nobody doubts that. This case is governed,
    however, by the Federal Constitution. The States do not,
    in the majority’s words, “retain autonomy to establish
    their own governmental processes,” ante, at 27, if those

    tions Clause, the State Constitution must give way.

    The majority opinion therefore largely misses the point.
    The relevant question in this case is how to define “the
    Legislature” under the Elections Clause. The majority
    opinion does not seriously turn to that question until page
    24, and even then it fails to provide a coherent answer.
    The Court seems to conclude, based largely on its under-
    standing of the “history and purpose” of the Elections
    Clause, ante, at 24, that “the Legislature” encompasses
    any entity in a State that exercises legislative power.
    That circular definition lacks any basis in the text of the
    Constitution or any other relevant legal source.
    The majority’s textual analysis consists, in its entirety,
    of one paragraph citing founding era dictionaries. The
    majority points to various dictionaries that follow Samuel
    Johnson’s definition of “legislature” as the “power that
    makes laws.” 
    Ibid. (internal quotation marks
    omitted).
    The notion that this definition corresponds to the entire
    population of a State is strained to begin with, and largely
    discredited by the majority’s own admission that “[d]irect
    lawmaking by the people was virtually unknown when the
    Constitution of 1787 was drafted.” Ante, at 3 (internal
    quotation marks omitted); see ante, at 27. Moreover, Dr.
    Johnson’s first example of the usage of “legislature” is this:
    “Without the concurrent consent of all three parts of the
    legislature, no law is or can be made.” 2 A Dictionary of
    the English Language (1st ed. 1755) (emphasis deleted).
    Johnson borrowed that sentence from Matthew Hale, who
    defined the “Three Parts of the Legislature” of England as
    the King and the two houses of Parliament. History of the
    Common Law of England 2 (1713). (The contrary notion
    that the people as a whole make the laws would have cost
    you your head in England in 1713.) Thus, even under the
    Cite as: 576 U. S. ____ (2015)            5
    ROBERTS, C. J., dissenting
    majority’s preferred definition, “the Legislature” referred
    to an institutional body of representatives, not the people
    at large.
    Any ambiguity about the meaning of “the Legislature” is
    removed by other founding era sources. “[E]very state
    constitution from the Founding Era that used the term
    legislature defined it as a distinct multimember entity
    comprised of representatives.” Morley, The Intratextual
    Independent “Legislature” and the Elections Clause, 109
    Nw. U. L. Rev. Online 131, 147, and n. 101 (2015) (citing
    eleven State Constitutions). The Federalist Papers are
    replete with references to “legislatures” that can only be
    understood as referring to representative institutions.
    E.g., The Federalist No. 27, pp. 174–175 (C. Rossiter ed.
    1961) (A. Hamilton) (describing “the State legislatures” as
    “select bodies of men”); 
    id., No. 60,
    at 368 (contrasting “the
    State legislatures” with “the people”). Noah Webster’s
    heralded American Dictionary of the English Language
    defines “legislature” as “[t]he body of men in a state or
    kingdom, invested with power to make and repeal laws.”
    2 An American Dictionary of the English Language (1828).
    It continues, “The legislatures of most of the states in
    America . . . consist of two houses or branches.” 
    Ibid. (emphasis deleted). I
    could go on, but the Court has said this before. As we
    put it nearly a century ago, “Legislature” was “not a term
    of uncertain meaning when incorporated into the Consti-
    tution.” 
    Hawke, 253 U.S., at 227
    . “What it meant when
    adopted it still means for the purpose of interpretation.”

    The unambiguous meaning of “the Legislature” in the
    Elections Clause as a representative body is confirmed by
    other provisions of the Constitution that use the same
    term in the same way. When seeking to discern the mean-
    ing of a word in the Constitution, there is no better dic-
    tionary than the rest of the Constitution itself. Our prece-
    dents new and old have employed this structural method
    of interpretation to read the Constitution in the manner it
    was drafted and ratified—as a unified, coherent whole.
    See, e.g., NLRB v. Noel Canning, 573 U. S. ___, ___–___
    (2014) (slip op., at 19–20); id., at ___ (SCALIA, J., concur-
    ring in judgment) (slip op., at 32); McCulloch v. Maryland,
    
    4 Wheat. 316

    1 Wheat. 304
    , 328–330 (1816); Amar, Intratextualism, 112
    Harv. L. Rev. 747 (1999).
    The Constitution includes seventeen provisions refer-
    ring to a State’s “Legislature.” See Appendix, infra.
    Every one of those references is consistent with the under-
    standing of a legislature as a representative body. More
    importantly, many of them are only consistent with an
    institutional legislature—and flatly incompatible with the
    majority’s reading of “the Legislature” to refer to the
    people as a whole.
    Start with the Constitution’s first use of the term: “The
    House of Representatives shall be composed of Members
    chosen every second Year by the People of the several
    States, and the Electors in each State shall have the Qual-
    ifications requisite for Electors of the most numerous
    Branch of the State Legislature.” Art. I, §2, cl. 1. This
    reference to a “Branch of the State Legislature” can only
    be referring to an institutional body, and the explicit
    juxtaposition of “the State Legislature” with “the People of
    the several States” forecloses the majority’s proposed
    reading.
    The next Section of Article I describes how to fill vacan-
    Cite as: 576 U. S. ____ (2015)              7
    ROBERTS, C. J., dissenting
    cies in the United States Senate: “if Vacancies happen by
    Resignation, or otherwise, during the Recess of the Legis-
    lature of any State, the Executive thereof may make tem-
    porary Appointments until the next Meeting of the Legis-
    lature, which shall then fill such Vacancies.” §3, cl. 2.1
    The references to “the Recess of the Legislature of any
    State” and “the next Meeting of the Legislature” are only
    consistent with an institutional legislature, and make no
    sense under the majority’s reading. The people as a whole
    (schoolchildren and a few unnamed others excepted) do
    not take a “Recess.”
    The list goes on. Article IV provides that the “United
    States shall guarantee to every State in this Union a
    Republican Form of Government, and shall protect each of
    them against Invasion; and on Application of the Legisla-
    ture, or of the Executive (when the Legislature cannot be
    convened), against domestic Violence.” §4. It is perhaps
    conceivable that all the people of a State could be “con-
    vened”—although this would seem difficult during an
    “Invasion” or outbreak of “domestic Violence”—but the
    only natural reading of the Clause is that “the Executive”
    may submit a federal application when “the Legislature”
    as a representative body cannot be convened.
    Article VI provides that the “Senators and Representa-
    tives before mentioned, and the Members of the several
    State Legislatures, and all executive and judicial Officers,
    both of the United States and of the several States, shall
    be bound by Oath or Affirmation, to support this Constitu-
    tion.” Cl. 3. Unless the majority is prepared to make all
    the people of every State swear an “Oath or Affirmation, to
    support this Constitution,” this provision can only refer
    to the “several State Legislatures” in their institutional
    capacity.
    Each of these provisions offers strong structural indica-

    ROBERTS, C. J., dissenting
    tions about what “the Legislature” must mean. But the
    most powerful evidence of all comes from the Seventeenth
    Amendment. Under the original Constitution, Senators
    were “chosen by the Legislature” of each State, Art. I, §3,
    cl. 1, while Members of the House of Representatives were
    chosen “by the People,” Art. I, §2, cl. 1. That distinction
    was critical to the Framers. As James Madison explained,
    the Senate would “derive its powers from the States,”
    while the House would “derive its powers from the people
    of America.” The Federalist No. 39, at 244. George Mason
    believed that the power of state legislatures to select
    Senators would “be a reasonable guard” against “the
    Danger . . . that the national, will swallow up the State
    Legislatures.” 1 Records of the Federal Convention of
    1787, p. 160 (M. Farrand ed. 1911). Not everyone agreed.
    James Wilson proposed allowing the people to elect Sena-
    tors directly. His proposal was rejected ten to one. De-
    bates in the Federal Convention of 1787, S. Doc. No. 404,
    57th Cong., 1st Sess., 8 (1902).
    Before long, reformers took up Wilson’s mantle and
    launched a protracted campaign to amend the Constitu-
    tion. That effort began in 1826, when Representative
    Henry Storrs of New York proposed—but then set aside—
    a constitutional amendment transferring the power to
    elect Senators from the state legislatures to the people. 2
    Cong. Deb. 1348–1349. Over the next three-quarters of a
    century, no fewer than 188 joint resolutions proposing
    similar reforms were introduced in both Houses of Con-
    gress. 1 W. Hall, The History and Effect of the Seven-
    teenth Amendment 183–184 (1936).
    At no point in this process did anyone suggest that a
    constitutional amendment was unnecessary because “Leg-
    islature” could simply be interpreted to mean “people.”
    See 
    Hawke, 253 U.S., at 228
    (“It was never suggested, so
    far as we are aware, that the purpose of making the office
    of Senator elective by the people could be accomplished by
    Cite as: 576 U. S. ____ (2015)           9
    ROBERTS, C. J., dissenting
    a referendum vote. The necessity of the amendment to
    accomplish the purpose of popular election is shown in the
    adoption of the amendment.”). In fact, as the decades
    rolled by without an amendment, 28 of the 45 States
    settled for the next best thing by holding a popular vote on
    candidates for Senate, then pressuring state legislators
    into choosing the winner. See, e.g., Abstract of Laws
    Relating to the Election of United States Senators, S. Doc.
    No. 393, 59th Cong., 2d Sess. (1907). All agreed that
    cutting the state legislature out of senatorial selection
    entirely would require nothing less than to “Strike out”
    the original words in the Constitution and “insert, ‘elected
    by the people’ ” in its place. Cong. Globe, 31st Cong., 1st
    Sess., 88 (1849) (proposal of Sen. Jeremiah Clemens).
    Yet that is precisely what the majority does to the Elec-
    tions Clause today—amending the text not through the
    process provided by Article V, but by judicial decision.
    The majority’s revision renders the Seventeenth Amend-
    ment an 86-year waste of time, and singles out the Elec-
    tions Clause as the only one of the Constitution’s seven-
    teen provisions referring to “the Legislature” that departs
    from the ordinary meaning of the term.
    The Commission had no answer to this point. See Tr. of
    Oral Arg. 42 (JUSTICE ALITO: “Is there any other provision
    where legislature means anything other than the conven-
    tional meaning?” Appellee: “I don’t know the answer to
    that question.”).
    The Court’s response is not much better. The majority
    observes that “the Legislature” of a State may perform
    different functions under different provisions of the Con-
    stitution. Under Article I, §3, for example, “the Legisla-
    ture” performed an “electoral” function by choosing Sena-
    tors. The “Legislature” plays a “consenting” function
    under Article I, §8, and Article IV, §3; a “ratifying” func-
    tion under Article V; and a “lawmaking” function under
    the Elections Clause. Ante, at 19, and n. 17. All true. The
    10         ARIZONA STATE LEGISLATURE v. ARIZONA
    INDEPENDENT REDISTRICTING COMM’N
    ROBERTS, C. J., dissenting
    majority, however, leaps from the premise that “the Legis-
    lature” performs different functions under different provi-
    sions to the conclusion that “the Legislature” assumes
    different identities under different provisions.
    As a matter of ordinary language and common sense,
    however, a difference in function does not imply a differ-
    ence in meaning. A car, for example, generally serves a
    transportation function. But it can also fulfill a storage
    function. At a tailgate party or a drive-in movie, it may
    play an entertainment function. In the absence of vacan-
    cies at the roadside motel, it could provide a lodging func-
    tion. To a neighbor with a dead battery, it offers an elec-
    tricity generation function. And yet, a person describing a
    “car” engaged in any of these varied functions would un-
    doubtedly be referring to the same thing.
    The Constitution itself confirms this point. Articles I
    and II assign many different functions to the Senate: a
    lawmaking function, an impeachment trial function, a
    treaty ratification function, an appointee confirmation
    function, an officer selection function, a qualification
    judging function, and a recordkeeping function. Art. I, §1;
    §3, cls. 5, 6; §5, cls. 1, 3; §7, cl. 2; Art. II, §2, cl. 2. Yet the
    identity of the Senate remains the same as it discharges
    these various functions.
    Similarly, the House of Representatives performs differ-
    ent functions, including lawmaking, impeachment, and
    resolving Presidential elections in which no candidate
    wins a majority in the Electoral College. Art. I, §1; §2,
    cl. 5; §7, cl. 2; Amdt. 12. The President is assigned not
    only executive functions, Art. II, but also legislative func-
    tions, such as approving or vetoing bills, convening both
    Houses of Congress, and recommending measures for their
    consideration, Art. I, §7, cl. 2; Art. II, §3. Courts not only
    exercise a judicial function, Art. III, §1, but may also
    perform an appointment function, Art. II, §2, cl. 2. And so
    on. Neither the majority nor the Commission points to a
    Cite as: 576 U. S. ____ (2015)           11
    ROBERTS, C. J., dissenting
    single instance in which the identity of these actors
    changes as they exercise different functions.
    The majority attempts to draw support from precedent,
    but our cases only further undermine its position. In
    Hawke, this Court considered the meaning of “the Legisla-
    tur[e]” in Article V, which outlines the process for ratifying
    constitutional amendments. The Court concluded that
    “Legislature” meant “the representative body which
    ma[kes] the laws of the 
    people.” 253 U.S., at 227
    . The
    Court then explained that “[t]he term is often used in the
    Constitution with this evident meaning.” 
    Ibid. (emphasis added). The
    Court proceeded to list other constitutional
    provisions that assign different functions to the “Legisla-
    ture,” just as the majority does today. 
    Id., at 227–228;
    see
    ante, at 19, n. 17.
    Unlike the majority today, however, the Court in Hawke
    never hinted that the meaning of “Legislature” varied
    across those different provisions because they assigned
    different functions. To the contrary, the Court drew infer-
    ences from the Seventeenth Amendment and its predeces-
    sor, Article I, §3—in which “the Legislature” played an
    electoral function—to define the “Legislature” in Article V,
    which assigned it a ratification function. 
    See 253 U.S., at 228
    . The Court concluded that “Legislature” refers to a
    representative body, whatever its function. As the Court
    put it, “There can be no question that the framers of the
    Constitution clearly understood and carefully used the
    terms in which that instrument referred to the action of
    the legislatures of the States. When they intended that
    direct action by the people should be had they were no less
    accurate in the use of apt phraseology to carry out such
    purpose.” 
    Ibid. (citing Art. I,
    §2).
    Smiley, the leading precedent on the meaning of “the
    Legislature” in the Elections Clause, reaffirmed the defini-
    tion announced in Hawke. In Smiley, the petitioner ar-
    gued—as the Commission does here—that “the Legisla-
    12         ARIZONA STATE LEGISLATURE v. ARIZONA
    INDEPENDENT REDISTRICTING COMM’N
    ROBERTS, C. J., dissenting
    ture” referred not just to “the two houses of the legisla-
    ture” but to “the entire legislative power of the state . . .
    however exercised.” Brief for Petitioner, O. T. 1931, No.
    617, p. 22 (internal quotation marks omitted). The Court
    did not respond by holding, as the majority today suggests,
    that “ ‘the Legislature’ comprises the referendum and the
    Governor’s veto in the context of regulating congressional
    elections,” or that “ ‘the Legislature’ has a different iden-
    tity” in the Elections Clause than it does in Article V. Ante,
    at 18–19. Instead, the Court in Smiley said this:
    “Much that is urged in argument with regard to the
    meaning of the term ‘Legislature’ is beside the point.
    As this Court said in Hawke . . . the term was not one
    ‘of uncertain meaning when incorporated into the
    Constitution. What it meant when adopted it still
    means for purposes of interpretation. A Legislature
    was then the representative body which made the
    laws of the people.’ 
    285 U.S., at 365
    (quoting
    
    Hawke, 253 U.S., at 227
    ).
    Remarkably, the majority refuses to even acknowledge
    the definition of “the Legislature” adopted in both Smiley
    and Hawke, and instead embraces the interpretation that
    this Court unanimously rejected more than 80 years ago.2
    C
    The history of the Elections Clause further supports the
    conclusion that “the Legislature” is a representative body.
    The first known draft of the Clause to appear at the Con-
    stitutional Convention provided that “Each state shall
    prescribe the time and manner of holding elections.” 1
    ——————
    2 The only hint of support the majority can glean from precedent is a
    passing reference in Atlantic Cleaners & Dyers, Inc. v. United States,
    
    286 U.S. 427
    , 434 (1932), a case about how to interpret “trade or
    commerce” in the Sherman Act. See ante, at 18. And even that selected

    Debates on the Federal Constitution 146 (J. Elliot ed.
    1836). After revision by the Committee of Detail, the
    Clause included the important limitation at issue here:
    “The times and places, and the manner, of holding the
    elections of the members of each house, shall be prescribed
    by the legislature of each state; but their provisions con-
    cerning them may, at any time, be altered by the legisla-
    ture of the United States.” 
    Id., at 225
    (emphasis added).
    The insertion of “the legislature” indicates that the Fram-
    ers thought carefully about which entity within the State
    was to perform congressional districting. And the parallel
    between “the legislature of each state” and “the legislature
    of the United States” further suggests that they meant
    “the legislature” as a representative body.
    As the majority explains, the debate over the ratification
    of the Elections Clause centered on its second part, which
    empowers Congress to “make or alter” regulations pre-
    scribed by “the Legislature” of a State. See ante, at 25–27.
    Importantly for our purposes, however, both sides in this
    debate “recognized the distinction between the state legis-
    lature and the people themselves.” Brown v. Secretary of
    State of Florida, 
    668 F.3d 1271
    , 1275–1276, n. 4 (CA11
    2012).
    The Anti-Federalists, for example, supported vesting
    election regulation power solely in state legislatures be-
    cause state “legislatures were more numerous bodies,
    usually elected annually, and thus more likely to be in
    sympathy with the interests of the people.” Natelson, The
    Original Scope of the Congressional Power to Regulate
    Elections, 13 U. Pa. J. Const. L. 1, 31 (2010) (emphasis
    added) (citing sources from ratification debates). Alexan-
    der Hamilton and others responded by raising the specter
    of state legislatures—which he described as “local admin-
    istrations”—deciding to “annihilate” the Federal Govern-
    ment by “neglecting to provide for the choice of persons to
    administer its affairs.” The Federalist No. 59, at 363. As

    the majority acknowledges, the distinction between “the
    Legislature” and the people “occasioned no debate.” Ante,
    at 27. That is because everybody understood what “the
    Legislature” meant.
    The majority contends that its counterintuitive reading
    of “the Legislature” is necessary to advance the “animat-
    ing principle” of popular sovereignty. Ante, at 24. But the
    ratification of the Constitution was the ultimate act of
    popular sovereignty, and the people who ratified the Elec-
    tions Clause did so knowing that it assigned authority to
    “the Legislature” as a representative body. The Elections
    Clause was not, as the majority suggests, an all-purpose
    “safeguard against manipulation of electoral rules by
    politicians.” Ante, at 26. Like most provisions of the
    Constitution, the Elections Clause reflected a compro-
    mise—a pragmatic recognition that the grand project of
    forging a Union required everyone to accept some things
    they did not like. See The Federalist No. 59, at 364 (de-
    scribing the power allocated to state legislatures as “an
    evil which could not have been avoided”). This Court has
    no power to upset such a compromise simply because we
    now think that it should have been struck differently. As
    we explained almost a century ago, “[t]he framers of the
    Constitution might have adopted a different method,” but
    it “is not the function of courts . . . to alter the method
    which the Constitution has fixed.”

    In addition to text, structure, and history, several prec-
    edents interpreting the Elections Clause further reinforce
    that “the Legislature” refers to a representative body.
    The first precedent comes not from this Court, but from
    Congress. Acting under its authority to serve as “the

    tives in 1866 confronted a dispute about who should be
    seated as the Congressman from the Fifth District of
    Michigan. At a popular convention, Michigan voters had
    amended the State Constitution to require votes to be cast
    within a resident’s township or ward. The Michigan Leg-
    islature, however, passed a law permitting soldiers to vote
    in alternative locations. If only the local votes counted,
    one candidate (Baldwin) would win; if the outside votes
    were included, the other candidate (Trowbridge) would be
    entitled to the seat. See Baldwin v. Trowbridge, 2 Bartlett
    Contested Election Cases, H. R. Misc. Doc. No. 152, 41st
    Cong., 2d Sess., 46–47 (1866).
    The House Elections Committee explained that the
    Elections Clause conferred power on “the Legislature” of
    Michigan to prescribe election regulations. “But,” the
    Committee asked, “what is meant by ‘the legislature?’
    Does it mean the legislative power of the State, which
    would include a convention authorized to prescribe fun-
    damental law; or does it mean the legislature eo nomine,
    as known in the political history of the country?” 
    Id., at 47.
    The Committee decided, and the full House agreed,
    that “the Legislature” in the Elections Clause was the
    “legislature eo nomine”—the legislature by that name, a
    representative body. 
    Ibid. That conclusion followed
    both
    from the known meaning of “the Legislature” at the time
    of the framing and the many other uses of the word in the
    Constitution that would not be compatible with a popular
    convention. Thus, “[w]here there is a conflict of authority
    between the constitution and legislature of a State in
    regard to fixing place of elections, the power of the legisla-
    ture is paramount.”

    16         ARIZONA STATE LEGISLATURE v. ARIZONA
    INDEPENDENT REDISTRICTING COMM’N
    ROBERTS, C. J., dissenting
    The majority draws attention to the minority report in
    Baldwin. Ante, at 29. Under the present circumstances, I
    take some comfort in the Court’s willingness to consider
    dissenting views. Still, the minority report does not di-
    minish the force of Baldwin. The report cites a Michigan
    Supreme Court precedent that allegedly reached a con-
    trary result, but that case turned entirely on state constitu-
    tional questions arising from a state election—not federal
    constitutional questions arising from a federal election.
    See People ex rel. Twitchell v. Blodgett, 
    13 Mich. 127
    (1865). The majority also contends that Baldwin “appears
    in tension with” an earlier House Elections Committee
    precedent. Ante, at 29. By its own terms, however, that
    earlier precedent did not involve a conflict between a state
    legislative act and a state constitutional provision. See
    Shiel v. Thayer, 1 Bartlett Contested Election Cases, H. R.
    Misc. Doc. No. 57, 38th Cong., 2d Sess., 350 (1861) (“the
    two branches of the legislature differed upon the question
    . . . and so the bill never became a law”). In any event, to
    the degree that the two precedents are inconsistent, the
    later decision in Baldwin should govern.3
    The next relevant precedent is this Court’s decision in
    McPherson v. Blacker, 
    146 U.S. 1
    (1892). That case in-
    volved a constitutional provision with considerable simi-
    larity to the Elections Clause, the Presidential Electors
    Clause of Article II: “Each State shall appoint, in such
    Manner as the Legislature thereof may direct, a Number of
    Electors . . . .” §1, cl. 2 (emphasis added). The question
    was whether the state legislature, as a body of representa-
    tives, could divide authority to appoint electors across
    each of the State’s congressional districts. The Court

    3 The majority’s suggestion that Baldwin should be dismissed as an
    act of partisanship appears to have no basis, unless one is willing to
    regard as tainted every decision in favor of a candidate from the same
    party as a majority of the Elections Committee. Ante, at 29–30.

    upheld the law and emphasized that the plain text of the
    Presidential Electors Clause vests the power to determine
    the manner of appointment in “the Legislature” of the
    State. That power, the Court explained, “can neither be
    taken away nor 
    abdicated.” 146 U.S., at 35
    (emphasis
    added; internal quotation marks omitted).
    Against that backdrop, the Court decided two cases
    regarding the meaning of “the Legislature” in the Elec-
    tions Clause. In Ohio ex rel. Davis v. Hildebrant, 
    241 U.S. 565
    (1916), the Ohio Legislature passed a congres-
    sional redistricting law. Under the Ohio Constitution,
    voters held a referendum on the law and rejected it. A
    supporter of the law sued on behalf of the State, contend-
    ing that the referendum “was not and could not be a part
    of the legislative authority of the State and therefore could
    have no influence on . . . the law creating congressional
    districts” under the Elections Clause. 
    Id., at 567.
       This Court rejected the challenger’s constitutional ar-
    gument as a nonjusticiable claim that the referendum
    “causes a State . . . to be not republican” in violation of the
    Guarantee Clause of the Constitution. 
    Id., at 569
    (citing
    Art. IV, §4). The Court also rejected an argument that
    Ohio’s use of the referendum violated a federal statute,
    and held that Congress had the power to pass that statute
    under the Elections Clause. 
    Id., at 568–569.
    Hildebrant
    in no way suggested that the state legislature could be
    displaced from the redistricting process, and Hildebrant
    certainly did not hold—as the majority today contends—
    that “the word [‘Legislature’ in the Elections Clause]
    encompassed a veto power lodged in the people.” Ante, at
    16.     Hildebrant simply approved a State’s decision to
    employ a referendum in addition to redistricting by the
    Legislature. 
    See 241 U.S., at 569
    . The result of the deci-
    sion was to send the Ohio Legislature back to the drawing
    board to do the redistricting.
    In Smiley, the Minnesota Legislature passed a law
    18        ARIZONA STATE LEGISLATURE v. ARIZONA
    INDEPENDENT REDISTRICTING COMM’N
    ROBERTS, C. J., dissenting
    adopting new congressional districts, and the Governor
    exercised his veto power under the State Constitution. As
    noted above, the Minnesota secretary of state defended the
    veto on the ground that “the Legislature” in the Elections
    Clause referred not just to “the two houses of the legisla-
    ture” but to “the entire legislative power of the state . . .
    however exercised.” This Court rejected that argument,
    reiterating that the term “Legislature” meant “the repre-
    sentative body which made the laws of the people.
    285 U.S., at 365
    (quoting 
    Hawke, 253 U.S., at 227
    ). The
    Court nevertheless went on to hold that the Elections
    Clause did not prevent a State from applying the usual
    rules of its legislative process—including a gubernatorial
    veto—to election regulations prescribed by the 
    legislature. 285 U.S., at 373
    . As in Hildebrant, the legislature was
    not displaced, nor was it redefined; it just had to start on a
    new redistricting plan.
    The majority initially describes Hildebrant and Smiley
    as holding that “redistricting is a legislative function, to be
    performed in accordance with the State’s prescriptions for
    lawmaking, which may include the referendum and the
    Governor’s veto.” Ante, at 19. That description is true, so
    far as it goes. But it hardly supports the result the major-
    ity reaches here. There is a critical difference between
    allowing a State to supplement the legislature’s role in the
    legislative process and permitting the State to supplant
    the legislature altogether. See 
    Salazar, 541 U.S., at 1095
    (Rehnquist, C. J., dissenting from denial of certiorari) (“to
    be consistent with Article I, §4, there must be some limit
    on the State’s ability to define lawmaking by excluding the
    legislature itself”). Nothing in Hildebrant, Smiley, or any
    other precedent supports the majority’s conclusion that
    imposing some constraints on the legislature justifies
    deposing it entirely.

    ROBERTS, C. J., dissenting
    *    *     *
    The constitutional text, structure, history, and prece-
    dent establish a straightforward rule: Under the Elections
    Clause, “the Legislature” is a representative body that,
    when it prescribes election regulations, may be required to
    do so within the ordinary lawmaking process, but may not
    be cut out of that process. Put simply, the state legisla-
    ture need not be exclusive in congressional districting, but
    neither may it be excluded.
    The majority’s contrary understanding requires it to
    accept a definition of “the Legislature” that contradicts the
    term’s plain meaning, creates discord with the Seven-
    teenth Amendment and the Constitution’s many other
    uses of the term, makes nonsense of the drafting and
    ratification of the Elections Clause, and breaks with the
    relevant precedents. In short, the effect of the majority’s
    decision is to erase the words “by the Legislature thereof ”
    from the Elections Clause. That is a judicial error of the
    most basic order. “It cannot be presumed that any clause
    in the constitution is intended to be without effect; and
    therefore such a construction is inadmissible.” Marbury v.
    Madison, 1 Cranch 137, 174 (1803).
    II
    The Court also issues an alternative holding that a
    federal statute, 
    2 U.S. C
    . §2a(c), permits Arizona to vest
    redistricting authority in the Commission. Ante, at 19–23.
    The majority does not contend that this statutory holding
    resolves the constitutional question presented, see ante, at
    23, so its reading of Section 2a(c) is largely beside the
    point. With respect, its statutory argument is also hard to
    take seriously. Section 2a(c) does not apply to this case.
    And even if it did, it would likely be unconstitutional.4
    ——————
    4 Not surprisingly, Section 2a(c) was barely raised below and was not
    addressed by the District Court. See ante, at 19, n. 18.
    20         ARIZONA STATE LEGISLATURE v. ARIZONA
    INDEPENDENT REDISTRICTING COMM’N
    ROBERTS, C. J., dissenting
    A
    Section 2a(c) establishes a number of default rules that
    govern the States’ manner of electing representatives
    “[u]ntil a State is redistricted in the manner provided by
    the law thereof.” Section 2a(c) is therefore “inapplicable
    unless the state legislature, and state and federal courts,
    have all failed to redistrict” the State. Branch v. Smith,
    
    538 U.S. 254
    , 275 (2003) (plurality opinion); see 
    id., at 298–300
    (O’Connor, J., concurring in part and dissenting
    in part). Here, the Commission has redistricted the State
    “in the manner provided by the law thereof.” So by its
    terms, Section 2a(c) does not come into play in this case.
    The majority spends several pages discussing Section
    2a(c), but it conspicuously declines to say that the statute
    actually applies to this case.5 The majority notes that the
    pre-1911 versions of Section 2a(c) applied only until “the
    legislature” redistricted the State, while the post-1911
    versions applied only until the State is redistricted “in the
    manner provided by the law thereof.” The majority also
    describes in detail the legislative history that accompanied
    the 1911 amendment. But if Section 2a(c) does not apply,
    its legislative history is doubly irrelevant.
    The majority seems to suggest that Section 2a(c) some-
    how indicates federal approval for the district lines that
    the Commission has drawn. See ante, at 23. But the
    statute does nothing of the sort. Section 2a(c) explains
    what rules apply “[u]ntil a State is redistricted”; it says
    nothing about what rules apply after a State is redis-
    tricted. And it certainly does not say that the State’s
    redistricting plan will by some alchemy become federal
    law. No legislative drafter remotely familiar with the English
    language would say that a State had to follow default
    ——————
    5 The majority is prepared to say that Section 2a(c) has more than
    “nothing to do with this case.” Ante, at 23, n. 22. Not exactly a ringing
    endorsement.

    rules “[u]ntil [it] is redistricted in the manner provided by
    the law thereof,” when what he meant was “any redistrict-
    ing plan that the State adopts shall become federal law.”
    And if the drafter was doing something as significant as
    transforming state law into federal law, he presumably
    would have taken care to make that dramatic step “unmis-
    takably clear.” Gregory v. Ashcroft, 
    501 U.S. 452
    , 460
    (1991) (internal quotation marks omitted). Tellingly, our
    most recent case on the meaning of Section 2a(c) seems
    not to have even considered the majority’s position. See
    Branch, 
    538 U.S. 254
    .
    Indeed, the majority does not even seem persuaded by
    its own argument. The majority quickly cautions, in
    discussing Section 2a(c), that “a State is required to com-
    ply with the Federal Constitution, the Voting Rights Act,
    and other federal laws when it draws and implements its
    district map.” Ante, at 22, n. 20. The majority therefore
    concludes that “nothing in §2a(c) affects a challenge to a
    state district map on the ground that it violates one or
    more of those federal requirements.” 
    Ibid. But here the
    Arizona Legislature has challenged “a state district map
    on the ground that it violates one . . . of those federal
    requirements”—the Elections Clause. If we take the
    majority at its word, nothing in Section 2a(c) should affect
    that challenge.
    B
    Not only is the majority’s reading of Section 2a(c) im-
    plausible as a matter of statutory interpretation, it would
    also likely violate the Constitution in multiple ways.
    First, the majority’s reading of Section 2a(c) as a statute
    approving the lines drawn by the Commission would
    seemingly authorize Congress to alter the Elections
    Clause. The first part of the Elections Clause gives state
    legislatures the power to prescribe regulations regarding
    the times, places, and manner of elections; the second part
    22       ARIZONA STATE LEGISLATURE v. ARIZONA
    INDEPENDENT REDISTRICTING COMM’N
    ROBERTS, C. J., dissenting
    of the Clause gives Congress the power to “make or alter
    such Regulations.” There is a difference between making
    or altering election regulations prescribed by the state
    legislature and authorizing an entity other than the state
    legislature to prescribe election regulations. In essence,
    the majority’s proposed reading permits Congress to use
    the second part of the Elections Clause to nullify the first.
    Yet this Court has expressly held that “Congress ha[s] no
    power to alter Article I, section 4 [the Elections Clause].”
    
    Smiley, 285 U.S., at 372
    ; see also Clinton v. City of New
    York, 
    524 U.S. 417
    (1998) (Congress may not circumvent
    Article I constraints on its lawmaking power); Chadha,
    
    462 U.S. 919
    (same).
    Second, the majority’s interpretation of Section 2a(c)
    would create a serious delegation problem. As a general
    matter, Congress may pass statutes that delegate some
    discretion to those who administer the laws. It is a well-
    accepted principle, however, that Congress may not dele-
    gate authority to one actor when the Constitution vests
    that authority in another actor. See Whitman v. American
    Trucking Assns., Inc., 
    531 U.S. 457
    , 472 (2001). The
    majority’s reading of Section 2a(c) contradicts that rule by
    allowing Congress to delegate federal redistricting author-
    ity to a state entity other than the one in which the Elec-
    tions Clause vests that authority: “the Legislature.”
    Third, the majority’s interpretation conflicts with our
    most recent Elections Clause precedent, Arizona v. Inter
    Tribal Council of Ariz., Inc., 
    570 U.S. 1
    (2013). There we
    explained that when Congress legislates under the Elec-
    tions Clause, it “necessarily displaces some element of a
    pre-existing legal regime erected by the States.” Id., at
    ___ (slip op., at 11). That is so because “the power the
    Elections Clause confers [on Congress] is none other than
    the power to pre-empt.” Id., at ___–___, (slip op., at 11–
    12). Put differently, “all action under the Elections Clause
    displaces some element of a pre-existing state regulatory
    Cite as: 576 U. S. ____ (2015)             23
    ROBERTS, C. J., dissenting
    regime, because the text of the Clause confers the power to
    do exactly (and only) that.” Id., at ___, n. 6 (slip op., at 11,
    n. 6). Under the majority’s interpretation of Section 2a(c),
    however, Congress has done the opposite of preempting or
    displacing state law—it has adopted state law.
    Normally, when “a serious doubt of constitutionality is
    raised, it is a cardinal principle that this Court will first
    ascertain whether a construction of the statute is fairly
    possible by which the question may be avoided.” Crowell
    v. Benson, 
    285 U.S. 22
    , 62 (1932). The multiple serious
    constitutional doubts raised by the majority’s interpreta-
    tion of Section 2a(c)—in addition to the sheer weakness of
    its reading as a textual matter—provide more than
    enough reason to reject the majority’s construction. Sec-
    tion 2a(c) does not apply to this case.
    III
    Justice Jackson once wrote that the Constitution speaks
    in “majestic generalities.” West Virginia Bd. of Ed. v.
    Barnette, 
    319 U.S. 624
    , 639 (1943). In many places it
    does, and so we have cases expounding on “freedom of
    speech” and “unreasonable searches and seizures.”
    Amdts. 1, 4. Yet the Constitution also speaks in some
    places with elegant specificity. A Member of the House of
    Representatives must be 25 years old. Art. I, §2, cl. 2.
    Every State gets two Senators. Art. I, §3, cl. 1. And the
    times, places, and manner of holding elections for those
    federal representatives “shall be prescribed in each State
    by the Legislature thereof.” Art. I, §4, cl. 1.
    For the reasons I have explained, there is no real doubt
    about what “the Legislature” means. The Framers of the
    Constitution were “practical men, dealing with the facts of
    political life as they understood them, putting into form
    the government they were creating, and prescribing in
    language clear and intelligible the powers that govern-
    ment was to take.” South Carolina v. United States, 199

    INDEPENDENT REDISTRICTING COMM’N
    ROBERTS, C. J., dissenting
    U. S. 437, 449 (1905). We ought to give effect to the words
    they used.
    The majority today shows greater concern about redis-
    tricting practices than about the meaning of the Constitu-
    tion. I recognize the difficulties that arise from trying to
    fashion judicial relief for partisan gerrymandering. See
    Vieth v. Jubelirer, 
    541 U.S. 267
    (2004); ante, at 1. But our
    inability to find a manageable standard in that area is no
    excuse to abandon a standard of meaningful interpretation
    in this area. This Court has stressed repeatedly that a
    law’s virtues as a policy innovation cannot redeem its
    inconsistency with the Constitution. “Failure of political
    will does not justify unconstitutional remedies.” 
    Clinton, 524 U.S., at 449
    (KENNEDY, J., concurring); see Stern v.
    Marshall, 564 U. S. ___ (2011); Free Enterprise Fund v.
    Public Company Accounting Oversight Bd., 
    561 U.S. 477
    (2010); Bowsher v. Synar, 
    478 U.S. 714
    (1986); Chadha,
    
    462 U.S. 919
    ; Myers v. United States, 
    272 U.S. 52
    (1926).
    Indeed, the Court has enforced the text of the Constitu-
    tion to invalidate state laws with policy objectives remi-
    niscent of this one. Two of our precedents held that States
    could not use their constitutions to impose term limits on
    their federal representatives in violation of the United
    States Constitution. Cook, 
    531 U.S. 510
    ; U. S. Term
    Limits, Inc. v. Thornton, 
    514 U.S. 779
    (1995). The people
    of the States that enacted these reforms surely viewed
    them as measures that would “place the lead rein in the
    people’s hands.” Ante, at 27. Yet the Court refused to
    accept “that the Framers spent significant time and energy
    in debating and crafting Clauses that could be easily
    evaded.” Term 
    Limits, 514 U.S., at 831
    . The majority
    approves just such an evasion of the Constitution today.6
    ——————
    6 Term Limits was of course not decided on the abstract principle that
    “the people should choose whom they please to govern them.” Ante, at
    27, n. 24

    ). If that were the rule, the people

    The Court also overstates the effects of enforcing the
    plain meaning of the Constitution in this case. There is no
    dispute that Arizona may continue to use its Commission
    to draw lines for state legislative elections. The repre-
    sentatives chosen in those elections will then be responsi-
    ble for congressional redistricting as members of the state
    legislature, so the work of the Commission will continue to
    influence Arizona’s federal representation.
    Moreover, reading the Elections Clause to require the
    involvement of the legislature will not affect most other
    redistricting commissions. As the majority notes, many
    States have commissions that play an “auxiliary role” in
    congressional redistricting. Ante, at 8, and nn. 8–9. But
    in these States, unlike in Arizona, the legislature retains
    primary authority over congressional redistricting. See
    Brief for National Conference of State Legislatures as
    Amicus Curiae 3–17.
    The majority also points to a scattered array of election-
    related laws and constitutional provisions enacted via
    popular lawmaking that it claims would be “endangered”
    by interpreting the Elections Clause to mean what it says.
    Ante, at 33. Reviewing the constitutionality of these far-
    flung provisions is well outside the scope of this case.
    Suffice it to say that none of them purports to do what the
    Arizona Constitution does here: set up an unelected, unac-
    countable institution that permanently and totally dis-
    places the legislature from the redistricting process.
    “[T]his wolf comes as a wolf.” Morrison v. Olson, 
    487 U.S. 654
    , 699 (1988) (SCALIA, J., dissenting).

    that inspired the Arizona Commission is any discussion of

    foreign President. But see Art. I, §2, cl. 2; §3, cl. 3; Art. II, §1, cl. 5.
    Term Limits instead relied on analysis of the text, structure, and
    history of the Constitution—all factors that cut strongly against the
    majority’s position today.

    how it has actually functioned. The facts described in a
    recent opinion by a three-judge District Court detail the
    partisanship that has affected the Commission on issues
    ranging from staffing decisions to drawing the district
    lines. See Harris v. Arizona Independent Redistricting
    Comm’n, 
    993 F. Supp. 2d 1042
    (Ariz. 2014). The per curiam
    opinion explained that “partisanship played some role
    in the design of the map,” that “some of the commissioners
    were motivated in part in some of the linedrawing deci-
    sions by a desire to improve Democratic prospects in the
    affected districts,” and that the Commission retained a
    mapping consultant that “had worked for Democratic,
    independent, and nonpartisan campaigns, but no Republi-
    can campaigns.” 
    Id., at 1046,
    1047, 1053. The hiring of
    the mapping consultant provoked sufficient controversy
    that the Governor of Arizona, supported by two-thirds of
    the Arizona Senate, attempted to remove the chairwoman
    of the Commission for “substantial neglect of duty and
    gross misconduct in office.”

    Republican plurality districts and underpopulation of
    Democratic plurality districts” as “old-fashioned partisan
    malapportionment.” 
    Id., at 1091,
    1108. In his words, the
    “Commission has been coin-clipping the currency of our
    democracy—everyone’s equal vote—and giving all the
    shavings to one party, for no valid reason.” 
    Id., at 1092.
       The District Court concluded by a two-to-one margin
    that this partisanship did not rise to the level of a consti-

    tutional violation. The case is pending on appeal before
    this Court, and I take no position on the merits question.
    But a finding that the partisanship in the redistricting
    plan did not violate the Constitution hardly proves that
    the Commission is operating free of partisan influence—
    and certainly not that it complies with the Elections
    Clause.
    *    *     *
    The people of Arizona have concerns about the process
    of congressional redistricting in their State. For better or
    worse, the Elections Clause of the Constitution does not
    allow them to address those concerns by displacing their
    legislature. But it does allow them to seek relief from
    Congress, which can make or alter the regulations pre-
    scribed by the legislature. And the Constitution gives
    them another means of change. They can follow the lead
    of the reformers who won passage of the Seventeenth
    Amendment. Indeed, several constitutional amendments
    over the past century have involved modifications of the
    electoral process. Amdts. 19, 22, 24, 26. Unfortunately,
    today’s decision will only discourage this democratic
    method of change. Why go through the hassle of writing a
    new provision into the Constitution when it is so much
    easier to write an old one out?
    I respectfully dissent.

    ARIZONA INDEPENDENT REDISTRICTING
    COMMISSION ET AL.
    ON APPEAL FROM THE UNITED STATES DISTRICT COURT FOR
    THE DISTRICT OF ARIZONA
    [June 29, 2015]
    JUSTICE SCALIA, with whom JUSTICE THOMAS joins,
    dissenting.
    I do not believe that the question the Court answers is
    properly before us.      Disputes between governmental
    branches or departments regarding the allocation of politi-
    cal power do not in my view constitute “cases” or “contro-
    versies” committed to our resolution by Art. III, §2, of the
    Constitution.
    What those who framed and ratified the Constitution
    had in mind when they entrusted the “judicial Power” to a
    separate and coequal branch of the Federal Government
    was the judicial power they were familiar with—that
    traditionally exercised by English and American courts.
    The “cases” and “controversies” that those courts enter-
    tained did not include suits between units of government
    regarding their legitimate powers. The job of the courts
    was, in Chief Justice Marshall’s words, “solely, to decide
    on the rights of individuals,” Marbury v. Madison, 1
    Cranch 137, 170 (1803). Tocqueville considered this one
    reason the new democracy could safely confer upon courts
    the immense power to hold legislation unconstitutional:
    “[B]y leaving it to private interest to censure the law,
    and by intimately uniting the trial of the law with the
    trial of an individual, legislation is protected from
    2        ARIZONA STATE LEGISLATURE v. ARIZONA
    INDEPENDENT REDISTRICTING COMM’N
    SCALIA, J., dissenting
    wanton assaults and from the daily aggressions of
    party spirit. . . .
    “I am inclined to believe this practice of the Ameri-
    can courts to be at once most favorable to liberty and
    to public order. If the judge could only attack the leg-
    islator only openly and directly, he would sometimes
    be afraid to oppose him; and at other times party spir-
    it might encourage him to brave it at every turn. . . .
    But the American judge is brought into the political
    arena independently of his own will. He judges the
    law only because he is obliged to judge a case. The po-
    litical question that he is called upon to resolve is
    connected with the interests of the parties, and he
    cannot refuse to decide it without a denial of justice.”
    A. de Tocqueville, Democracy in America 102-03 (P.
    Bradley ed. 1948).
    That doctrine of standing, that jurisdictional limitation
    upon our powers, does not have as its purpose (as the
    majority assumes) merely to assure that we will decide
    disputes in concrete factual contexts that enable “realistic
    appreciation of the consequences of judicial action,” ante,
    at 14. To the contrary. “[T]he law of Art. III standing is
    built on a single basic idea—the idea of separation of
    powers.” Allen v. Wright, 
    468 U.S. 737
    , 752 (1984). It
    keeps us minding our own business.
    We consult history and judicial tradition to determine
    whether a given “ ‘disput[e is] appropriately resolved
    through the judicial process.’ ” Lujan v. Defenders of Wild-
    life, 
    504 U.S. 555
    , 560 (1992) (internal quotation marks
    omitted). What history and judicial tradition show is that
    courts do not resolve direct disputes between two political
    branches of the same government regarding their respec-
    tive powers.     Nearly every separation-of-powers case
    presents questions like the ones in this case. But we have
    never passed on a separation-of-powers question raised
    Cite as: 576 U. S. ____ (2015)            3
    SCALIA, J., dissenting
    directly by a governmental subunit’s complaint. We have
    always resolved those questions in the context of a private
    lawsuit in which the claim or defense depends on the
    constitutional validity of action by one of the governmen-
    tal subunits that has caused a private party concrete
    harm. That is why, for example, it took this Court over 50
    years to rule upon the constitutionality of the Tenure of
    Office Act, passed in 1867. If the law of standing had been
    otherwise, “presumably President Wilson, or Presidents
    Grant and Cleveland before him, would . . . have had
    standing, and could have challenged the law preventing
    the removal of a Presidential appointee without the con-
    sent of Congress.” Raines v. Byrd, 
    521 U.S. 811
    , 828
    (1997).
    We do not have to look far back in the United States
    Reports to find other separation-of-powers cases which, if
    the Arizona Legislature’s theory of standing is correct,
    took an awfully circuitous route to get here. In Zivotofsky
    v. Kerry, ante, p. ___, the President could have sued for an
    injunction against Congress’s attempted “direct usurpa-
    tion” of his constitutionally-conferred authority to pro-
    nounce on foreign relations. Or in Wellness Int’l Network,
    Ltd. v. Sharif, 575 U. S. ___ (2015), a Federal District
    Judge could have sought a declaratory judgment that a
    bankruptcy court’s adjudicating a Stern claim improperly
    usurped his constitutionally conferred authority to decide
    cases and controversies. Or in NLRB v. Noel Canning,
    573 U. S. ___ (2014), the Senate could have sued the Pres-
    ident, claiming a direct usurpation of its prerogative to
    advise on and consent to Presidential appointments. Each
    of these cases involved the allocation of power to one or
    more branches of a government; and we surely would have
    dismissed suits arising in the hypothesized fashions.
    We have affirmatively rejected arguments for jurisdic-
    tion in cases like this one. For example, in 
    Raines, 521 U.S., at 829
    –830, we refused to allow Members of Con-
    4        ARIZONA STATE LEGISLATURE v. ARIZONA
    INDEPENDENT REDISTRICTING COMM’N
    SCALIA, J., dissenting
    gress to challenge the Line Item Veto Act, which they
    claimed “ ‘unconstitutionally expand[ed] the President’s
    power’ ” and “ ‘alter[ed] the constitutional balance of pow-
    ers between the Legislative and Executive Branches.’ ”
    
    Id., at 816.
    In Massachusetts v. Mellon, 
    262 U.S. 447
    ,
    479–480 (1923), we refused to allow a State to pursue its
    claim that a conditional congressional appropriation “con-
    stitute[d] an effective means of inducing the States to
    yield a portion of their sovereign rights.” (And Mellon
    involved a contention that one government infringed upon
    another government’s power—far closer to the traditional
    party-versus-party lawsuit than is an intragovernmental
    dispute.) We put it plainly: “In the last analysis, the
    complaint of the plaintiff State is brought to the naked
    contention that Congress has usurped the reserved powers
    of the several States,” 
    id., at 483—and
    because the State
    could not show a discrete harm except the alleged usurpa-
    tion of its powers, we refused to allow the State’s appeal.
    The sole precedent the Court relies upon is Coleman v.
    Miller, 
    307 U.S. 433
    (1939). Coleman can be distin-
    guished from the present case as readily as it was distin-
    guished in Raines. In Raines, the accurate-in-fact (but
    inconsequential-in-principle) distinction was that the
    Senators in Coleman had their votes nullified, whereas the
    Members of Congress claimed that their votes could merely
    be rendered ineffective by a Presidential line-item veto.
    
    Raines, supra, at 823
    –824. In the present case we could
    make the accurate-in-fact distinction that in Coleman
    individual legislators were found to have standing, whereas
    here it is the governmental body, the Arizona Legisla-
    ture, that seeks to bring suit. But the reality is that the
    supposed holding of Coleman stands out like a sore thumb
    from the rest of our jurisprudence, which denies standing
    for intragovernmental disputes.
    Coleman was a peculiar case that may well stand for
    nothing. The opinion discussing and finding standing, and
    Cite as: 576 U. S. ____ (2015)            5
    SCALIA, J., dissenting
    going on to affirm the Kansas Supreme Court, was written
    by Chief Justice Hughes and announced by Justice Stone.
    Justice Frankfurter, joined by three other Justices, held
    there was no standing, and would have dismissed the
    petition (leaving the judgment of the Kansas Supreme
    Court in place). Justice Butler, joined by Justice McRey-
    nolds, dissented (neither joining Hughes’s opinion nor
    separately discussing standing) and would have reversed
    the Kansas Supreme Court.
    That adds up to two votes to affirm on the merits, two to
    reverse on the merits (without discussing standing) and
    four to dismiss for lack of standing. Justice Stanley Reed,
    who was on the Court and apparently participated in the
    case, is not mentioned in any of the opinions recorded in
    the United States Reports. So, in order to find Coleman a
    binding precedent on standing, rather than a 4-to-4 stand-
    off, one must assume that Justice Reed voted with
    Hughes. There is some reason to make that assumption:
    The four Justices rejecting standing went on to discuss the
    merits, because “the ruling of the Court just announced
    removes from the case the question of petitioners’ standing
    to 
    sue.” 307 U.S., at 456
    (Black, J., concurring). But then
    again, if nine Justices participated, how could it be that on
    one of the two issues in the case the Court was “equally
    divided and therefore . . . expresse[d] no opinion”? 
    Id., at 447.
       A pretty shaky foundation for a significant precedential
    ruling. Besides that, the two dissenters’ mere assumption
    of standing—neither saying anything about the subject
    nor joining Hughes’s opinion on the point—produces (if
    you assume Reed joined Hughes) a majority for standing
    but no majority opinion explaining why. And even under
    the most generous assumptions, since the Court’s judg-
    ment on the issue it resolved rested on the ground that
    that issue presented a political question—which is itself a
    rejection of jurisdiction, Zivotofsky v. Clinton, 
    566 U.S. 6
           ARIZONA STATE LEGISLATURE v. ARIZONA
    INDEPENDENT REDISTRICTING COMM’N
    SCALIA, J., dissenting
    ___ (2012) (slip op., at 5)—Coleman’s discussion of the
    additional jurisdictional issue of standing was quite super-
    fluous and arguably nothing but dictum. The peculiar
    decision in Coleman should be charitably ignored.
    The Court asserts, quoting 
    Raines, 521 U.S., at 819
    –
    820, that the Court’s standing analysis has been “especially
    rigorous when reaching the merits of the dispute would
    force [the Court] to decide whether an action taken by one
    of the other two branches of the Federal Government was
    unconstitutional.” Ante, at 14, n. 12. The cases cited to
    support this dictum fail to do so; they are merely cases
    where a determination of unconstitutionality is avoided by
    applying what there is no reason to believe is anything
    other than normal standing requirements. It seems to me
    utterly implausible that the Framers wanted federal
    courts limited to traditional judicial cases only when they
    were pronouncing upon the rights of Congress and the
    President, and not when they were treading upon the
    powers of state legislatures and executives. Quite to the
    contrary, I think they would be all the more averse to
    unprecedented judicial meddling by federal courts with
    the branches of their state governments.
    I would dismiss this case for want of jurisdiction.
    *     *    *
    Normally, having arrived at that conclusion, I would
    express no opinion on the merits unless my vote was
    necessary to enable the Court to produce a judgment. In
    the present case, however, the majority’s resolution of the
    merits question (“legislature” means “the people”) is so
    outrageously wrong, so utterly devoid of textual or historic
    support, so flatly in contradiction of prior Supreme Court
    cases, so obviously the willful product of hostility to dis-
    tricting by state legislatures, that I cannot avoid adding
    my vote to the devastating dissent of the Chief Justice.

    ARIZONA INDEPENDENT REDISTRICTING
    COMMISSION ET AL.
    ON APPEAL FROM THE UNITED STATES DISTRICT COURT FOR
    THE DISTRICT OF ARIZONA
    [June 29, 2015]
    JUSTICE THOMAS, with whom JUSTICE SCALIA joins,
    dissenting.
    Reading today’s opinion, one would think the Court is a
    great defender of direct democracy in the States. As it
    reads “the Legislature” out of the Times, Places and Man-
    ner Clause, U. S. Const., Art. I, §4, the majority offers a
    paean to the ballot initiative. It speaks in glowing terms
    of the “characteristic of our federal system that States
    retain autonomy to establish their own governmental
    processes.” Ante, at 27. And it urges “[d]eference to state
    lawmaking” so that States may perform their vital func-
    tion as “ ‘laboratories’ ”of democracy. Ante, at 28.
    These sentiments are difficult to accept. The conduct of
    the Court in so many other cases reveals a different atti-
    tude toward the States in general and ballot initiatives in
    particular. Just last week, in the antithesis of deference
    to state lawmaking through direct democracy, the Court
    cast aside state laws across the country—many of which
    were enacted through ballot initiative—that reflected the
    traditional definition of marriage. See Obergefell v. Hodges,
    ante, p. ___.
    This Court’s tradition of disdain for state ballot initia-
    tives goes back quite a while. Two decades ago, it held
    unconstitutional an Arkansas ballot initiative imposing
    2         ARIZONA STATE LEGISLATURE v. ARIZONA
    INDEPENDENT REDISTRICTING COMM’N
    THOMAS, J., dissenting
    term limits on that State’s Members of Congress, finding
    “little significance” in the fact that such term limits were
    adopted by popular referendum. U. S. Term Limits, Inc. v.
    Thornton, 
    514 U.S. 779
    , 822, n. 32 (1995). One year later,
    it held unconstitutional a ballot initiative that would have
    prevented the enactment of laws under which “ ‘homosex-
    ual, lesbian or bisexual orientation, conduct, practices or
    relationships [would] constitute or otherwise be the basis
    of . . . any minority status, quota preferences, protected
    status or claim of discrimination.’ ” Romer v. Evans, 
    517 U.S. 620
    , 624 (1996). The Court neither gave deference to
    state lawmaking nor said anything about the virtues of
    direct democracy. It instead declared that the result of the
    ballot initiative was an aberration—that “[i]t is not within
    our constitutional tradition to enact laws of this sort.” 
    Id., at 633.
    But if “constitutional tradition” is the measuring
    stick, then it is hard to understand how the Court con-
    dones a redistricting practice that was unheard of for
    nearly 200 years after the ratification of the Constitution
    and that conflicts with the express constitutional com-
    mand that election laws “be prescribed in each State by
    the Legislature thereof,” Art. I, §4.
    The Court’s lack of respect for ballot initiatives is evi-
    dent not only in what it has done, but in what it has failed
    to do. Just this Term, the Court repeatedly refused to
    review cases in which the Courts of Appeals had set aside
    state laws passed through ballot initiative. See, e.g.,
    County of Maricopa v. Lopez-Valenzuela, 575 U. S. ___
    (2015) (THOMAS, J., dissenting from denial of certiorari)
    (state constitutional amendment denying bail for illegal
    aliens arrested in certain circumstances); Herbert v. Kitchen,
    574 U. S. ___ (2014) (state constitutional amendment
    retaining traditional definition of marriage); Smith v.
    Bishop, 574 U. S. ___ (2014) (same); Rainey v. Bostic, 574
    U. S. ___ (2014) (same); Walker v. Wolf, 574 U. S. ___
    (2014) (same). It did so despite warnings that its indiffer-
    Cite as: 576 U. S. ____ (2015)             3
    THOMAS, J., dissenting
    ence to such cases would “only embolden the lower courts
    to reject state laws on questionable constitutional
    grounds.” 
    Lopez-Valenzuela, supra
    , at ___ (slip op., at 2).
    And it refused to grant a stay pending appeal of a decision
    purporting to require the State of Alabama to issue mar-
    riage licenses to same-sex couples, even though Alabama’s
    licensing laws had not been challenged in that case. See
    Strange v. Searcy, 574 U. S. ___ (2015) (THOMAS, J., dis-
    senting from denial of application for stay). In each deci-
    sion, the cheers for direct democracy were conspicuously
    absent.
    Sometimes disapproval of ballot initiatives has been
    even more blatant. Just last Term, one dissenting opinion
    castigated the product of a state ballot initiative as “sty-
    mieing the right of racial minorities to participate in the
    political process.” Schuette v. BAMN, 572 U. S. ___, ___
    (2014) (SOTOMAYOR, J., joined by GINSBURG, J., dissent-
    ing) (slip op., at 1). It did not hail the ballot initiative as
    the result of a “State’s empowerment of its people,” ante,
    at 19, nor offer any deference to state lawmaking. In-
    stead, it complained that “[t]he majority of Michigan
    voters changed the rules in the middle of the game, recon-
    figuring the existing political process . . . .” Schuette, 572
    U. S., at ___ (slip op., at 4). And it criticized state ballot
    initiatives as biased against racial minorities because such
    minorities “face an especially uphill battle” in seeking the
    passage of such initiatives. Id., at ___ (slip op., at 20).
    How quickly the tune has changed.
    And how striking that it changed here. The ballot initi-
    ative in this case, unlike those that the Court has previ-
    ously treated so dismissively, was unusually democracy-
    reducing. It did not ask the people to approve a particular
    redistricting plan through direct democracy, but instead to
    take districting away from the people’s representatives
    and give it to an unelected committee, thereby reducing
    democratic control over the process in the future. The
    4         ARIZONA STATE LEGISLATURE v. ARIZONA
    INDEPENDENT REDISTRICTING COMM’N
    THOMAS, J., dissenting
    Court’s characterization of this as direct democracy at its
    best is rather like praising a plebiscite in a “banana repub-
    lic” that installs a strongman as President for Life. And
    wrapping the analysis in a cloak of federalism does little
    to conceal the flaws in the Court’s reasoning.
    I would dispense with the faux federalism and would
    instead treat the States in an evenhanded manner. That
    means applying the Constitution as written. Although the
    straightforward text of Article I, §4, prohibits redistricting
    by an unelected, independent commission, Article III
    limits our power to deciding cases or controversies. Be-
    cause I agree with JUSTICE SCALIA that the Arizona Legis-
    lature lacks Article III standing to assert an institutional
    injury against another entity of state government, I would
    dismiss its suit. I respectfully dissent.
