    MEMORANDUM OPINION FOR THE
    ASSOCIATE ATTORNEY GENERAL
    In your role as co-chair of the President’s Task Force on Puerto Rico’s
    Status, you asked us to consider whether “the President [may] support and
    Congress enact legislation that triggers implementation of whichever
    status outcome the citizens of Puerto Rico choose with no further action
    by Congress (with the understanding that such legislation may not be
    binding on future Congresses).” 1 This memorandum memorializes advice
    we provided to you prior to the release of the Report by the President’s
    Task Force in March 2011. 2 For the reasons given below, we concluded
    that legislation conditioning a change in Puerto Rico’s political relation-

    (“2011 Task Force Report”). President Clinton established the President’s Task Force on
    Puerto Rico’s Status by executive order on December 23, 2000. See Exec. Order No.
    13183, 3 C.F.R. 340 (2001), reprinted as amended in 48 U.S.C. § 731 note (2006 & Supp.
    IV 2010). As amended by subsequent executive orders, this order provides that the Task
    Force is “composed of designees of each member of the President’s Cabinet and the
    Deputy Assistant to the President and Director for Intergovernmental Affairs,” and is co-
    chaired by the Attorney General’s designee and the Deputy Assistant to the President and
    Director for Intergovernmental Affairs. Id. § 2; see Exec. Order No. 13517, 
    74 Fed. Reg. 57,239

    13209, 3 C.F.R. 765 (2002). The Task Force is responsible for, among other things, “en-
    sur[ing] official attention to and facilitat[ing] action on matters related to proposals for
    Puerto Rico’s status and provid[ing] advice and recommendations on such matters to the
    President and the Congress.” Exec. Order No. 13183, § 3.

    ship with the United States on the results of one or more referenda by the
    Puerto Rican electorate, without subsequent congressional action, would
    be constitutional, insofar as the referendum or referenda presented voters
    in the territory with a limited set of options specified in advance by Con-
    gress.
    Congress generally may condition the legal effect of legislation on the
    existence of future contingencies, including whether an affected constitu-
    ency approves the legislation. Neither of the clauses of the Constitution
    relevant here—the Territory Clause or the State Admission Clause—
    restricts Congress’s authority to enact legislation that would condition a
    change in a territory’s political relationship with the United States on the
    outcome of a territorial referendum. Moreover, an extensive and long-
    standing congressional practice of granting statehood or independence to
    territories upon approval by the territory’s electorate and without the need
    for subsequent congressional action confirms the constitutionality of this
    method for changing a territory’s status. This Office and various Depart-
    ment officials repeatedly have endorsed this view over the years, includ-
    ing with respect to Puerto Rico.
    We note at the outset that there are limitations on Congress’s authority
    to provide for certain outcomes. The Executive Branch, for example, has
    long taken the position that Congress may not constitutionally provide for
    the so-called “enhanced commonwealth” status, to the extent that such
    status would entail requiring the consent of the Puerto Rican people
    before Congress could make any subsequent changes in Puerto Rico’s
    political relationship with the United States. 3 In this memorandum, we
    address only the constitutionality of a particular process by which a
    change in Puerto Rico’s relationship with the United States might be
    brought about: a process that would involve the passage of federal legis-
    lation that would condition its own effects on the outcome of a vote by
    Puerto Rico’s electorate and would not require any subsequent action by
    Congress.

    The Supreme Court has described Puerto Rico as having “a relationship
    to the United States ‘that has no parallel in our history.’” Califano v.

    Eng’rs, Architects & Surveyors v. Flores de Otero, 
    426 U.S. 572
    , 596
    (1976)). The United States acquired Puerto Rico from Spain in 1898,
    pursuant to the Treaty of Paris that concluded the Spanish-American War.
    Over time, in successive organic statutes that established local govern-
    mental institutions for the territory, Congress gave Puerto Rico increasing
    degrees of autonomy. Puerto Rico acquired its current status as a self-
    governing “commonwealth” through federal statutes passed in 1950 and
    1952. The former authorized the Puerto Rican people to adopt a constitu-
    tion for Puerto Rico’s local self-government, and the latter approved the
    proposed constitution (subject to the inclusion of certain amendments).
    See Pub. L. No. 82-447, 66 Stat. 327 (1952); Pub. L. No. 81-600, 64 Stat.
    319 (1950) (codified at 48 U.S.C. §§ 731b–731e (2006)). 4
    Today, Puerto Rico has extensive powers of self-government. In “many
    respects,” its government “resembles that of a state,” in that it consists of
    “an elected governor and legislature, and its legislature has powers akin to
    those exercised by the states.” Trailer Marine Transp. Corp. v. Rivera
    Vazquez, 
    977 F.2d 1
    , 7 (1st Cir. 1992); see also Examining Bd., 
    426 U.S. at 594
     (Puerto Rico possesses “the degree of autonomy and independence
    normally associated with States of the Union”). Indeed, for many federal
    administrative purposes, Puerto Rico is treated as the functional equiva-
    lent of a State. In 1992, President George H.W. Bush issued a directive
    that remains in force today, requiring:
    all Federal departments, agencies, and officials, to the extent con-
    sistent with the Constitution and the laws of the United States,
    henceforward to treat Puerto Rico administratively as if it were a
    State, except insofar as doing so with respect to an existing Federal
    program or activity would increase or decrease Federal receipts or
    expenditures, or would seriously disrupt the operation of such pro-
    gram or activity.

    (2006).
    For constitutional purposes, Puerto Rico nonetheless remains a territory
    of the United States and is therefore subject to the Territory Clause and
    the State Admission Clause—constitutional provisions that give Congress
    the general authority to govern territories and the specific authority to
    admit new territories as states, respectively. 5 See U.S. Const. art. IV, § 3.
    The question thus becomes whether either of these two provisions, or any
    other constitutional requirement, precludes Congress from changing
    Puerto Rico’s relationship with the United States through legislation that
    would condition the effect of that legislation on the results of a vote by
    the Puerto Rican electorate.
    As a general matter, Congress may enact legislation conditioning the
    effectiveness of laws or regulations on approval by affected parties, 6 and
    we conclude that neither the Territory Clause nor the State Admission
    Clause prevents Congress from enacting such legislation to change Puerto

    Altering Puerto Rico’s Relationship with the United States Through Referendum
    Rico’s status. First, under the Territory Clause, Congress has “[p]ower to
    dispose of and make all needful Rules and Regulations respecting the
    Territory or other Property belonging to the United States.” U.S. Const.
    art. IV, § 3, cl. 2. The Supreme Court has characterized this clause as
    “grant[ing] Congress and the President the power to acquire, dispose of,
    and govern territory.” Boumediene v. Bush, 
    553 U.S. 723
    , 765 (2008). It
    has long been established that Congress’s authority to govern and dispose
    of territories includes the authority to provide for changes in territories’
    degree of self-government, 7 and to provide for even more fundamental
    changes in their political relationship with the United States, including by
    granting them independence. 8 Nothing in the text, structure, or purpose of
    the Territory Clause limits Congress’s authority to provide for a change in
    a territory’s governmental structure through the referendum process under
    consideration here, nor are we aware of any judicial decisions articulating
    such limits. In addition, nothing in the Clause would prevent Congress
    from making any change in Puerto Rico’s status effective upon a favora-
    ble vote by the territory’s electorate and without need for subsequent
    congressional action.
    Second, though the State Admission Clause places certain express limi-
    tations on Congress’s authority to create new states, these limitations
    would not apply to the admission of Puerto Rico. The Clause provides:
    New States may be admitted by the Congress into this Union; but no
    new State shall be formed or erected within the Jurisdiction of any
    other State; nor any State be formed by the Junction of two or more
    States, or Parts of States, without the Consent of the Legislatures of
    the States concerned as well as of the Congress.
    U.S. Const. art. IV, § 3, cl. 1. The State of Puerto Rico would neither be
    formed within the jurisdiction of any other state nor formed by the junc-
    7 See, e.g., United States v. Lara,

    litical branches” historically have made “radical adjustments” in the “autonomous status
    of . . . dependent entities,” including Puerto Rico); Calero-Toledo,

    tion of parts of two or more states. What is more, the Clause includes no
    express limitation on Congress’s authority to condition the admission of a
    state on an affirmative vote of a territory’s electorate without subsequent
    congressional action. In fact, as described in detail below, Congress has
    often admitted states through such means.
    II.
    A.
    Congress has frequently admitted states to the Union through contin-
    gent legislation. While the conditions Congress has imposed have varied,
    contingent statutes have often made admission of a territory effective
    upon the issuance of a presidential proclamation certifying that the statu-
    tory conditions have been fulfilled, without any subsequent action by
    Congress having been required. Congress has identified a vote by the
    territorial electorate in favor of statehood or in support of a state constitu-
    tion (or constitutional amendment) as the triggering event for admission
    in many instances.
    The two newest states—Alaska and Hawaii—were both admitted un-
    der statutes that conditioned admission on a referendum of the territorial
    electorate. In the case of Alaska, the statehood statute directed the gov-
    ernor of the territory to submit three propositions to the territory’s voters.
    Act of July 7, 1958, Pub. L. No. 85-508, § 8(b), 72 Stat. 339, 343–44.
    One of these propositions asked voters: “Shall Alaska immediately be
    admitted into the Union as a State?” Id., 72 Stat. at 344. The other two
    sought Alaska voters’ consent to specific territorial boundaries and
    certain other conditions of Alaska’s admission under the Act. Id. The
    Act required the governor to “certify the results of said submission, as
    . . . ascertained [by the Secretary of Alaska through a specified pro-
    cess], to the President of the United States.” Id.
    The statehood statute ultimately provided that, “[i]n the event any one
    of the [specified] propositions is not adopted at [the designated] election
    by a majority of the legal votes cast on said submission, the provisions of
    this Act shall thereupon cease to be effective,” meaning that Alaska would
    not become a state under the statute. Id. If the propositions were ap-
    proved, however, the Act authorized admission of Alaska upon presiden-
    tial proclamation, without further action by Congress. The Act provided:
    98
    Altering Puerto Rico’s Relationship with the United States Through Referendum
    If the President shall find that the propositions set forth in [the Act]
    have been duly adopted by the people of Alaska, the President, upon
    certification of the returns of the election of the [congressional Rep-
    resentative and Senators] required to be elected [under the Act], shall
    thereupon issue his proclamation announcing the results of said elec-
    tion as so ascertained. Upon the issuance of said proclamation by the
    President, the State of Alaska shall be deemed admitted into the Un-
    ion as provided in section 1 of this Act.
    Id. § 8(c), 72 Stat. at 344. Section 1 of the Act in turn provided “[t]hat,
    subject to the provisions of this Act, and upon issuance of the proclama-
    tion required by section 8(c) of this Act, the State of Alaska is hereby
    declared to be a State of the United States of America[] [and] is declared
    admitted into the Union on an equal footing with the other States in all
    respects whatever.” Id. § 1, 72 Stat. at 339.
    President Eisenhower signed the Alaska Statehood bill on July 7, 1958,
    and said he was “pleased with the action of Congress admitting Alaska.”
    Statement by the President Upon Signing Alaska Statehood Bill (July 7,
    1958), 1 Pub. Papers of Dwight D. Eisenhower 525 (1958). On January 3,
    1959, after Alaska voters had considered the propositions contemplated
    by the statute, the President issued the required proclamation “find[ing]
    and announc[ing] that the people of Alaska have duly adopted the propo-
    sitions required to be submitted to them by the act of July 7, 1958 and
    have duly elected the officers required to be elected by that act.” Procla-
    mation No. 3269, 3 C.F.R. 16 (Supp. 1959), reprinted in 48 U.S.C. ch. 2
    note following table of contents (2006). President Eisenhower thus “de-
    clare[d] and proclaim[ed] that the procedural requirements imposed by the
    Congress on the State of Alaska to entitle that State to admission into the
    Union have been complied with in all respects and that admission of the
    State of Alaska into the Union on an equal footing with the other States of
    the Union is now accomplished.” Id.
    Congress enacted Hawaii’s statehood statute several months after Alas-
    ka’s admission and provided for a virtually identical admissions process.
    Congress required Hawaii’s voters to answer three questions similar to
    those specified in the Alaska referendum, including “Shall Hawaii imme-
    diately be admitted into the Union as a State?” Pub. L. No. 86-3, § 7(b),
    73 Stat. 4, 7 (1959). Congress also required the election of a congressional
    Representative and Senators for Hawaii; directed the President to issue a
    99
    
    36 Op. O.L.C. 93
     (2012)
    proclamation certifying when these conditions were satisfied; and provid-
    ed that “[u]pon the issuance of said proclamation by the President, the
    State of Hawaii shall be deemed admitted into the Union as provided in
    section 1 of this Act.” 
    Id.
     The Act, like the Alaska statute, established
    that, “subject to the provisions of this Act, and upon issuance of the
    proclamation required by [the Act], the State of Hawaii is hereby declared
    to be a State of the United States of America[] [and] is declared to be
    admitted into the Union on an equal footing with the other States in all
    respects whatever.” 
    Id.
     §§ 1, 7, 73 Stat. at 4, 7–8. Upon signing the Ha-
    waii statehood bill, President Eisenhower observed that “[i]t has given me
    great satisfaction to sign the Act providing for the admission of Hawaii
    into the Union” and noted that, “[u]nder this legislation, the citizens of
    Hawaii will soon decide whether their Islands shall become our fiftieth
    State.” Statement by the President Upon Signing the Hawaii Statehood
    Bill (Mar. 18, 1959), 1 Pub. Papers of Dwight D. Eisenhower 286 (1959).
    After the territorial referendum, the President issued the required procla-
    mation certifying Hawaii’s admission to the union on August 21, 1959.
    Proclamation No. 3309, 3 C.F.R. 60 (Supp. 1959), reprinted in 48 U.S.C.
    ch. 3 note following table of contents (2006).
    Although Alaska and Hawaii are the only states whose admission was
    conditioned on referenda that expressly addressed statehood, Congress
    has admitted some ten other states pursuant to statutes that granted state-
    hood once territorial voters had approved certain measures, without fur-
    ther congressional action. Congress made the admission of Arizona and
    West Virginia effective upon popular ratification of certain amendments
    to the proposed state constitutions. 9 Similarly, Congress provided for the
    admission of Oklahoma, Utah, Washington, Montana, South Dakota,
    North Dakota, Colorado, and Nevada effective upon presidential procla-
    mation, without further congressional action, once territorial voters had
    approved state constitutions meeting specified criteria. 10

    Congress also has passed contingent admission legislation for territo-
    ries that were ultimately admitted under different, subsequent legislation,
    in some cases because voters in the territory rejected the conditions im-
    posed by Congress in the original contingent legislation. See, e.g., Pub. L.
    No. 59-234, §§ 24, 26, 34 Stat. 267, 278, 280–81 (1906) (providing for
    admission of State of Arizona following voter approval of constitution,
    but only if voters in the territories of both Arizona and New Mexico
    answered in the affirmative, “Shall Arizona and New Mexico be united to
    form one state?”) 11; Act of Apr. 19, 1864, ch. 59, § 5, 13 Stat. 47, 48–49

    Congress did not require that the vote result in any particular outcome. See S.J. Res. 57,
    §§ 3–6, 37 Stat. 39, 39–42 (Aug. 21, 1911) (requiring “as a condition precedent” to
    admission that the New Mexico electorate vote on specified amendments to the New
    Mexico constitution); Proclamation of Jan. 6, 1912, 37 Stat. 1723 (finding that vote was
    held and thus deeming New Mexico admitted to Union); Robert W. Larson, New Mexico’s
    Quest for Statehood: 1846–1912 296 (1968).
    11 Arizona voters rejected this proposition. See John D. Leshy, The Making of the Ari-
    zona Constitution, 20 Ariz. St. L.J. 1, 15–16 (1988).
    12 A constitutional convention convened pursuant to this statute failed to approve a
    constitution. 2 The Uniting States: The Story of Statehood for the Fifty United States 739–
    40 (Benjamin F. Shearer ed., 2004). Nebraska was later admitted under a different statute.
    See infra note 16.
    13 Kansas voters rejected the pro-slavery constitution on which this admission statute
    was based. Kansas was later admitted by statute with a different state constitution. See
    Act of Jan. 29, 1861, ch. 20, 12 Stat. 126; 1 Uniting States, supra note 12, at 450–51.
    14 Wisconsin voters rejected a constitution proposed pursuant to this Act, but Congress
    later admitted Wisconsin by statute following the ratification of a different state constitu-

     (2012)
    1845, ch. 48, §§ 2, 4, 5 Stat. 742, 743 (providing for admission of Iowa
    upon popular approval of conditions, including specified boundaries for
    the State, set forth in the act) 15; Act of June 15, 1836, ch. 96, §§ 2, 3, 5
    Stat. 49, 49–50 (providing for admission of Michigan upon acceptance of
    boundary conditions by popularly elected convention). 16
    The historical record thus provides overwhelming support for the con-
    clusion that Congress may adopt legislation that would authorize Puerto
    Rico’s admission as a State, effective upon approval by the Puerto Rican
    electorate.
    B.
    In addition to enacting contingent legislation to govern transitions to
    statehood, Congress has relied on such legislation to accomplish other
    tion. See Act of May 29, 1848, ch. 50, 9 Stat. 233; 3 Uniting States, supra note 12, 1344,
    1346.
    15 Iowa voters rejected these conditions, but Iowa was later admitted by statute with
    adjusted boundaries. See Act of Dec. 28, 1846, ch. 1, 9 Stat. 117; Act of Aug. 4, 1846,
    ch. 82, 9 Stat. 52; 1 Uniting States, supra note 12, at 424.
    16 The first convention elected pursuant to this statute rejected the boundary condi-
    tions, but a second convention accepted them and Congress admitted Michigan by statute,
    declaring the conditions in its prior enactment satisfied. See Act of Jan. 26, 1837, ch. 6,
    5 Stat. 144; 2 Uniting States, supra note 12, at 610–14.
    In other cases, Congress has provided for admission of territories as States upon presi-
    dential proclamation following satisfaction of conditions that did not necessarily involve a
    referendum. See Act of Feb. 9, 1867, ch. 36, § 3, 14 Stat. 391, 392 (conditioning Nebras-
    ka’s admission on the legislature’s declaration of assent to “the fundamental condition
    that within the State of Nebraska there shall be no denial of the elective franchise, or of
    any other right, to any person, by reason of race or color, excepting Indians not taxed”);
    Proclamation of Mar. 1, 1867, 14 Stat. 820 (deeming condition satisfied and Nebraska
    admitted as a state); J. Res. No. 1 of Mar. 2, 1821, 3 Stat. 645 (conditioning Missouri’s
    admission upon the legislature’s assent, “by a solemn public act,” to the “fundamental
    condition” that a provision in the proposed Missouri state constitution “shall never be
    construed to authorize the passage of any law, and that no law shall be passed in conform-
    ity thereto, by which any citizen, of either of the states in this Union, shall be excluded
    from the enjoyment of any of the privileges and immunities to which such citizen is
    entitled under the constitution of the United States”); Proclamation of Aug. 10, 1821,

    teen months after enactment).
    102
    Altering Puerto Rico’s Relationship with the United States Through Referendum
    changes in territories’ political relationship with the United States, includ-
    ing transitions to independence.
    In 1933 and 1934, for example, Congress passed contingent legislation
    providing for the independence of the Philippines, which had become a
    United States territory in 1898 after the Spanish-American War and
    through the Treaty of Paris. Both statutes provided that the Philippines
    would acquire independence upon issuance of a presidential proclamation,
    without further congressional action, ten years after the formation of a
    new Philippine government pursuant to a popularly ratified constitution
    that satisfied certain requirements. 17 The Philippine legislature rejected
    the terms of the 1933 Act, but the territory ultimately acquired independ-
    ence under the 1934 Act. 18
    In the 1934 Act, Congress authorized the Philippine legislature to pro-
    vide for the drafting, by elected delegates, of a constitution that met the
    Act’s requirements. Id. §§ 1–2, 48 Stat. at 456–58. The Act required that
    the constitution be submitted for the President’s review within two years
    of the Act’s enactment. If the President certified that the constitution
    “conform[ed] substantially with the provisions of [the] Act,” the constitu-
    tion was to be submitted “to the people of the Philippine Islands for their
    ratification or rejection at an election to be held within four months after
    the date of such certification.” Id. §§ 3–4, 48 Stat. at 458. Under the Act,
    a majority vote in favor of the constitution was to be “deemed an expres-
    sion of the will of the people of the Philippine Islands in favor of Philip-
    pine independence.” Id. § 4. Following ratification of such a constitution,
    the Governor General of the territory was to provide for an election of
    officers under the new constitution, and upon certification of the results of
    this election, the President was required to “issue a proclamation an-
    nouncing the results of the election.” Id. § 4, 48 Stat. at 458–59. The Act
    provided that “upon the issuance of such proclamation by the President

    Id.
     The Act required the President to issue a
    further proclamation surrendering United States control of the territory
    and recognizing Philippine independence on July Fourth, ten years after
    the inauguration of this new government. 
    Id.
     § 10, 48 Stat. at 463; see
    also J. Res. of June 29, 1944, § 3, 58 Stat. 625, 626 (authorizing the
    President “to advance the date of the independence of the Philippine
    Islands by proclaiming their independence as a separate and self-
    governing nation prior to July 4, 1946”).
    In accordance with the terms of this Act, President Roosevelt recog-
    nized, by proclamation effective November 15, 1935, the formation of a
    new constitutional government for the Philippines. On July 4, 1946,
    President Truman proclaimed the independence of the Philippines. See
    Proclamation No. 2148, 49 Stat. 3481 (1935); Proclamation No. 2695,
    3 C.F.R. 86, 86 (1946), reprinted in 60 Stat. 1352 (1946), and in 22
    U.S.C. § 1394 note (2006).
    More recently, the United States altered its political relationship with
    Palau through legislation that conditioned the change on a vote by the
    territorial electorate. After World War II, Palau became part of a “trust
    territory” of the United States under the United Nations Charter. See,
    e.g., Morgan Guar. Trust Co. of N.Y. v. Republic of Palau, 
    924 F.2d 1237
    , 1237–40 (2d Cir. 1991). In the 1980s, the United States negotiated
    a “Compact of Free Association” with the territory, according to which
    Palau would become a sovereign republic while maintaining extensive
    ties with the United States. See Compact of Free Association, Pub. L. No.
    99-658, § 201, 100 Stat. 3672, 3678–79 (1986); see generally Stanley K.
    Laughlin, Jr., The Law of United States Territories and Affiliated Juris-
    dictions 461–78 (1995) (“Laughlin”). The compact provided that it would
    take effect only upon approval by the United States and Palau govern-
    ments according to each government’s constitutional processes, and
    approval by Palau’s voters in a plebiscite. See Compact of Free Associa-
    tion § 411, 100 Stat. at 3698.
    Congress initially approved this compact in a 1986 statute that re-
    quired enactment of a further joint resolution before the compact could
    take effect. Pub. L. No. 99-658, § 101(a), (d)(1)(B), 100 Stat. at 3673,
    3674. But in 1989, Congress passed a second statute authorizing “entry
    into force” of the compact, following a specified period of notice to
    104
    Altering Puerto Rico’s Relationship with the United States Through Referendum
    Congress, “subject to the condition that the Compact, as approved by the
    Congress in [the first statute], is approved by the requisite percentage of
    votes cast in a referendum conducted pursuant to the Constitution of
    Palau, and such approval is free from any legal challenge.” Pub. L. No.
    101-219, § 101, 103 Stat. 1870, 1870 (1989). 19 Palau voters approved
    the compact by plebiscite on November 9, 1993, and on September 27,
    1994, President Clinton issued a proclamation deeming the compact
    effective as of October 1, 1994. The proclamation declared that “Palau
    will thereafter be self-governing and no longer subject to [United States]
    Trusteeship.” Proclamation No. 6726, 3 C.F.R. 104, 105 (1994), reprint-
    ed in 108 Stat. 5631, 5632 (1994). Palau thus gained full independence
    under legislation that authorized the change in status upon the occurrence
    of a future contingency—voter approval in a plebiscite—without further
    action by Congress. 20
    Even Puerto Rico itself previously has undergone a significant change
    in its political relationship with the United States as a result of self-
    executing contingent legislation. In 1950, in Public Law 81-600, Congress
    established a process through which Puerto Rico’s voters could adopt a
    constitution for the local government of the territory. The statute, howev-
    er, made the drafting of a new constitution contingent upon approval of
    the Act’s terms by a majority of voters participating in “an island-wide
    referendum to be held in accordance with the laws of Puerto Rico.” Id.
    § 2, 64 Stat. at 319. Moreover, Public Law 81-600 provided that a consti-
    tution drafted and approved in accordance with the Act’s procedures
    would “become effective” only “[u]pon approval by the Congress,” id.
    19  The Palau Supreme Court ruled initially that a provision in Palau’s constitution re-
    garding nuclear materials on the island necessitated seventy-five percent approval for
    ratification of the compact, a decision that resulted in several failed votes to ratify the
    compact. Palau’s constitution was eventually amended to allow approval of the compact
    by majority vote. See Chimene I. Keitner & W. Michael Reisman, Free Association: The
    United States Experience, 39 Tex. Int’l L.J. 1, 50–51 (2003); Laughlin at 98–100, 477–78.
    20 Two other states formed from the Trust Territory of the Pacific Islands—the Repub-
    lic of the Marshall Islands and the Federated States of Micronesia—also entered into
    compacts of free association with the United States. These territories, however, approved
    the compacts in plebiscites prior to approval of the compacts by Congress. See Proclama-
    tion No. 5564, 
    51 Fed. Reg. 40,399
     (Nov. 3, 1986) (describing plebiscite in Federated
    States of Micronesia on June 21, 1983, and in the Marshall Islands on September 7,
    1983), reprinted in 48 U.S.C. § 1801 note (2006); Pub. L. No. 99-239, 99 Stat. 1770
    (1986) (providing congressional approval of compacts for these territories).

     (2012)
    § 3, 64 Stat. at 319, and Congress ultimately provided such approval only
    in further contingent legislation. Specifically, in 1952, Congress approved
    a locally adopted constitution for Puerto Rico, but provided that certain
    provisions would have “no force and effect” until specified amendments
    were adopted “by the people of Puerto Rico.” Congress also provided that
    the constitution as a whole would “become effective” only “when the
    Constitutional Convention [that drafted the constitution] shall have de-
    clared in a formal resolution its acceptance in the name of the people of
    Puerto Rico of the conditions of approval herein contained, and when the
    Governor of Puerto Rico, being duly notified by the proper officials of the
    Constitutional Convention of Puerto Rico that such resolution of ac-
    ceptance has been formally adopted, shall issue a proclamation to that
    effect.” Pub. L. No. 82-447, 66 Stat. at 327–28. In accordance with the
    terms of this statute, the Puerto Rican Constitutional Convention adopted
    the required resolution, and the Governor of Puerto Rico deemed the
    constitution effective in a proclamation issued on July 25, 1952. 21
    Considered in combination with Congress’s longstanding and repeated
    use of contingent legislation to admit territories as states, these examples
    of the Philippines’ and Palau’s transitions to independence and Puerto
    Rico’s acquisition of commonwealth status present a powerful historical
    case for the permissibility of legislation that authorizes an alteration of
    Puerto Rico’s status as triggered by a vote of the Puerto Rican electorate.
    See, e.g., Mistretta v. United States, 
    488 U.S. 361
    , 401 (1989) (“‘tradi-
    tional ways of conducting government . . . give meaning’ to the Constitu-

    Altering Puerto Rico’s Relationship with the United States Through Referendum
    III.
    In accord with the analysis offered above, this Office and the Depart-
    ment of Justice have indicated on many occasions that Congress may
    provide for a change in Puerto Rico’s status, contingent upon actions by
    the Puerto Rican electorate, without the need for subsequent congressional
    action.
    In 1959, this Office reviewed a bill that would have provided for ad-
    mission of Puerto Rico as a State upon presidential proclamation, without
    further congressional action, following ratification of a state constitution
    and election of congressional representatives by Puerto Rico voters. See
    Memorandum for Lawrence E. Walsh, Deputy Attorney General, from
    Robert Kramer, Assistant Attorney General, Office of Legal Counsel, Re:
    H.R. 7003, 86th Cong., 1st Sess., a bill “To provide for a referendum in
    Puerto Rico on the admission of Puerto Rico into the Union as a State,
    and to establish the procedure for such admission if the people of Puerto
    Rico desire it” (Oct. 12, 1959) (“Kramer Memo”); H.R. 7003, 86th Cong.
    § 206(a) (as introduced in House, May 7, 1959). We questioned the pro-
    priety of “using this procedure in the case of Puerto Rico,” because it
    would have provided for admission of Puerto Rico without prior congres-
    sional review of the state constitution to be adopted by the territory, thus
    reducing congressional “control” over the procedure. But we expressed no
    uncertainty about the constitutional permissibility of the procedure in the
    bill. On the contrary, we noted that it was “patterned upon one of the
    methods frequently used to admit states to the Union” and that “a great
    many territories [had] secured admission as the result of a single act
    passed by the Congress” establishing similar preconditions. Kramer
    Memo at 2, 3.
    Thirty years later, our Office provided advice regarding “the general
    legal requirements for admitting Puerto Rico to the Union.” Memorandum
    for Thomas M. Boyd, Assistant Attorney General, Office of Legislative
    Affairs, from John O. McGinnis, Deputy Assistant Attorney General,
    Office of Legal Counsel, Re: Statehood for Puerto Rico at 1 (Mar. 3,
    1989). Explaining that “Congress has employed a variety of methods to
    admit new States into the Union,” we gave a summary description of
    some of the types of contingent legislation Congress has used to grant
    statehood, including making admission effective upon the results of a
    107
    
    36 Op. O.L.C. 93
     (2012)
    territorial vote following adoption of a constitution. “Congress . . . may
    set conditions for a territory to meet before it becomes a state,” we ex-
    plained, so long as the conditions do not “violate some other textual
    provision of the Constitution or . . . interfere with essential aspects of
    state sovereignty, such as dictating the location of the state capital.” 
    Id. 22
    In the same year, this Office and the Department commented on S. 712,
    a bill that would have provided for self-executing changes in Puerto
    Rico’s status based on the results of a plebiscite. 23 Although the Depart-
    ment expressed concerns about other aspects of the bill, including con-
    cerns related to the proposed referendum process, it did not suggest that
    Congress lacked authority to provide for a change in Puerto Rico’s politi-
    cal relationship with the United States contingent on a referendum in
    Puerto Rico. 24 On the contrary, the Acting Deputy Attorney General
    stated in testimony that “[t]he Administration strongly supports the right
    of the people of Puerto Rico to choose their political status by means of a
    referendum,” and that “the referendum can present options that, if select-
    22
    The Supreme Court has found the so-called “equal footing” doctrine implicit in the
    terms “State” and “Union” in the provisions governing admission of States. According to
    the doctrine, all states in the Union must stand on terms of “constitutional equality” with
    all other states regardless of when they were admitted, and Congress, therefore, may not
    “deprive[]” a new state of “any of the power constitutionally possessed by other States.”

    Band of Chippewa Indians, 
    526 U.S. 172
    , 203–04 (1999). At the same time, the Court has
    recognized that Congress “may require, under penalty of denying admission,” that a
    territory seeking admission as a State satisfy certain conditions before being admitted to
    the Union. Coyle,

    ed by a majority of the voters in Puerto Rico, can immediately be imple-

    In the following Congress, the Attorney General raised concerns about
    legislation similar to S. 712 that was not self-executing, but rather called
    for specified House and Senate Committee Chairmen to introduce legisla-
    tion, with terms prescribed by the bill, that would have enacted a particu-
    lar outcome upon approval by voters in Puerto Rico through a referen-
    dum. See S. 244, 102d Cong. § 101(e)–(f) (as introduced in Senate, Jan.
    23, 1991). Attorney General Thornburgh observed that, “[i]f Congress
    intends to truly commit itself to implement whatever status option re-
    ceives a majority in accordance with [the bill], it should return to the self-
    executing approach and language of S. 712.” Political Status of Puerto

    (1990).
    These past statements by the Justice Department provide further sup-
    port for the constitutionality of legislation conditioning a self-executing
    change in Puerto Rico’s political relationship with the United States on
    the results of a referendum in Puerto Rico.
    IV.
    In light of the permissibility of contingent legislation and the numerous
    historical precedents for legislation that conditions both statehood and
    independence on votes by territorial electorates without the need for
    subsequent congressional action, we think it clear that Congress may
    provide that a change in Puerto Rico’s political relationship with the
    United States will take effect upon approval of the change by Puerto
    Rico’s voters.

     (2012)
    We recognize that the legislation currently being contemplated, like
    some of the prior bills concerning Puerto Rico’s status discussed in Part
    III, may provide voters in Puerto Rico with more than two status options
    from which to choose; the legislation might include statehood, independ-
    ence, and a modified commonwealth relationship as alternatives. See, e.g.,
    S. 712, 101st Cong. § 2 (as introduced in Senate, Apr. 5, 1989) (providing
    for options of “statehood,” “independence,” or “commonwealth” to take
    effect, in accordance with terms and procedures set forth in the bill,
    following approval by a majority of voters in an initial referendum or
    runoff referendum). In this respect, the legislation would depart from the
    historical practice we have reviewed, where contingent legislation provid-
    ed territorial voters with only two status options. This divergence might
    form the basis of an argument that a referendum offering voters more than
    two status options would cross a constitutional line by impermissibly
    delegating Congress’s authority to territorial voters.
    In our judgment, however, this potential, limited divergence from his-
    torical practice is immaterial to our constitutional analysis. Congress
    historically has offered to territorial electorates two choices—statehood
    (or in some cases independence) on the one hand, and continued territorial
    status on the other—each of which was acceptable to Congress, and each
    of which came with different legal and policy implications. Congress thus
    has given territorial electorates ultimate control over whether their territo-
    ries have become states (or occupied some other status), as would be the
    case with a referendum that offered Puerto Rico voters three choices. As
    we note above, see supra note 6 and accompanying text, Congress may
    enact legislation conditioning the effectiveness of a law on approval by
    affected parties. 26 In our view, as long as Congress offered Puerto Rico
    voters a limited range of options specified in advance, it would make no
    meaningful constitutional difference whether those options numbered two
    26 The outcome of voting on referenda that specify a limited set of options remains
    simply a “condition[]” that Congress has “exercise[d] its legislative authority” to “pre-
    scribe[e] [as] the condition[] of [the statute’s] application.” Currin,

    also Clinton v. City of New York, 
    524 U.S. 417
    , 443–44 (1998) (indicating the permissi-
    bility of legislation that makes specified results “contingent upon a condition that did not
    exist when the [statute] was passed,” requires executive officials to effectuate that result
    upon occurrence of the contingency, and provides for execution of a “policy that Congress
    had embodied in the statute”).

    Altering Puerto Rico’s Relationship with the United States Through Referendum
    or three, and the process for resolving Puerto Rico’s status would not
    present delegation concerns. We therefore conclude that the present
    proposals for referenda would be lawful.
