    SUMMARY*
    Indian Law
    The panel affirmed the district court’s summary judgment
    in an action challenging the constitutionality of H.B. 2534, an
    Arizona law that allows a city or town within populous
    counties to annex certain surrounding, unincorporated lands.
    The Tohono O’odham Nation purchased unincorporated
    land in Maricopa County, Arizona. The Nation alleged that
    H.B. 2534 was enacted in order to block the federal
    government from taking the land it purchased into trust on
    behalf of the Nation, a process that would render the land part
    of the Nation’s reservation pursuant to the Gila Bend Indian
    Reservation Lands Replacement Act. H.B. 2534 was enacted
    *
    This summary constitutes no part of the opinion of the court. It has
    been prepared by court staff for the convenience of the reader.
    TOHONO O’ODHAM NATION V. STATE OF ARIZONA                3
    after the Nation announced its intention to build a casino on
    “Parcel 2” of the land, and after the Secretary of the Interior
    decided to take Parcel 2 into trust.
    The panel affirmed the district court’s holding that H.B.
    2534 is preempted by the Gila Bend Indian Reservation
    Lands Replacement Act because it stands as an obstacle to the
    accomplishment and execution of the full purposes and
    objectives of the Act¯namely, to enable the Secretary to take
    Parcel 2 into trust and thereby incorporate the land into tribal
    land. The panel concluded that under H.B. 2534, the City of
    Glendale, Arizona, purportedly had the authority¯at the
    point when the Nation filed a trust application¯to
    preemptively annex unincorporated land and effectively block
    the trust application.
    The panel thus affirmed the legality of the Secretary’s
    taking of Parcel 2 into trust pursuant to the Act. It did not
    reach the Nation’s other challenges to H.B. 2534.

    OPINION
    M. SMITH, Circuit Judge:
    This appeal involves a dispute concerning 135 acres of
    unincorporated land within Maricopa County, Arizona that
    was purchased by Plaintiff, the Tohono O’odham Nation (the
    Nation). The Nation filed suit against the City of Glendale
    and the State of Arizona (collectively, Defendants),
    challenging the constitutionality of H.B. 2534, a law passed
    by the Arizona legislature that allows a city or town within
    populous counties to annex certain surrounding,
    unincorporated lands.
    The Nation alleges that H.B. 2534 was enacted to block
    the federal government from taking the 135 acres it purchased
    into trust on behalf of the Nation—a process that would
    render the land part of the Nation’s reservation pursuant to
    the Gila Bend Indian Reservation Lands Replacement Act,
    Pub. L. No. 99-503, 100 Stat. 1798 (1986) (the Act). The
    Nation asserts that H.B. 2534 is preempted by the Act,
    violates the Equal Protection and Due Process Clauses of the
    U.S. and Arizona Constitutions, and violates the Arizona
    Constitution’s prohibition against special legislation. The
    parties filed cross summary judgment motions. The district
    court ruled in favor of the Nation as to the federal preemption
    TOHONO O’ODHAM NATION V. STATE OF ARIZONA               5
    claim, and ruled in favor of Defendants as to the remaining
    claims. We affirm.
    FACTUAL AND PROCEDURAL BACKGROUND
    I. Tribal Land
    The Tohono O’odham Nation, formerly known as the
    Papago Tribe, is a federally recognized Indian tribe with over
    28,000 members. The tribe is descended from Native
    Americans who resided for centuries along the banks of the
    Gila River in Arizona. In 1882, by executive order, President
    Chester A. Arthur set aside for the Nation a 22,400-acre Gila
    Bend Reservation in southwestern Arizona. The size of the
    reservation was later reduced to 10,297 acres by executive
    order of President William Howard Taft. In 1960, in order to
    provide flood protection to non-tribal areas, the federal
    government completed construction of the Painted Rock
    Dam, located on the Gila River approximately ten miles from
    the Gila Bend Reservation. In subsequent decades, flooding
    from the dam caused major damage to the reservation,
    destroying farm land and rendering the reservation land
    economically unviable. The Nation was left with “a
    reservation which for all practical purposes [could not] be
    used to provide any kind of sustaining economy.” The
    Nation sought a legislative remedy, rather than engaging in
    lengthy litigation, and petitioned Congress for a new
    reservation on lands that would be suitable for agriculture.
    II. Gila Bend Indian Reservation Lands Replacement Act
    In 1982, pursuant to section 308 of the Southern Arizona
    Water Rights Settlement Act, Pub. L. No. 97-293, 96 Stat.
    1261 (1982), Congress recognized its trust responsibility to
    6      TOHONO O’ODHAM NATION V. STATE OF ARIZONA
    find a different land base for the Nation. Section 308
    authorized the Secretary of the Interior (the Secretary) to
    conduct a study of the reservation, and to find lands suitable
    for a tribal reservation. The ensuing study concluded that the
    reservation land had little economic value and was unsuitable
    for agriculture or grazing. Another study found that there
    were no public lands within a 100-mile radius of the
    reservation that were suitable as potential exchange properties
    for the reservation.
    In 1986, Congress passed the Act to facilitate the
    replacement of the reservation lands, and to promote the
    economic self-sufficiency of the Nation. Pub. L. No. 99-503,
    § 2. The Act (1) authorized the Nation to assign 9,880 acres
    of tribal land within the Gila Bend Indian Reservation to the
    federal government in exchange for $30,000,000; (2)
    authorized the Nation to purchase up to 9,880 acres of private
    land, which would, at the request of the Nation, be held in
    trust for the tribe, and thereby be incorporated into tribal land;
    and (3) released the Nation’s claims against the United States
    for past injuries to land and water rights. Pub. L. No. 99-503,
    §§ 4(a), 6(c)-(d), 9(a). The Act requires that purchased
    private land be held in trust and not be “outside the counties
    of Maricopa, Pinal, and Pima, Arizona, or within the
    corporate limits of any city or town.” 
    Id. § 6(d).
    In 1987, the
    Nation assigned its rights in the reservation lands and
    relinquished its claims against the United States.
    III.     Acquisition of Land and Trust Application
    In August 2003, the Nation purchased 135 acres of
    unincorporated land within Maricopa County, Arizona (the
    Replacement Lands) for $13.8 million. The Replacement
    Lands are wholly located in an unincorporated “county
    TOHONO O’ODHAM NATION V. STATE OF ARIZONA                7
    island,” surrounded on all sides by land incorporated within
    the City of Glendale (the City), and include, among other
    properties, a 54-acre portion known as Parcel 2.
    On January 28, 2009, the Nation filed an application with
    the Bureau of Indian Affairs, requesting that the Replacement
    Lands be taken into trust pursuant to the Act. At the same
    time, the Nation publicly revealed its plan to build a casino on
    Parcel 2 of the Replacement Lands pursuant to the authority
    of the Indian Gaming Regulatory Act, 25 U.S.C. §§ 2701-
    2721 (IGRA). Pursuant to the IGRA, gaming activities may
    only take place on land that is part of an Indian reservation.
    Thus, having at least some portion of the Replacement Land
    held in trust—which transforms the land into tribal land—is
    a precondition to the Nation’s conducting gaming operations
    on that portion of the land. On March 12, 2010, as a result of
    an ongoing state-court action, the Nation modified its
    application to request that only Parcel 2 of the Replacement
    Lands be taken into trust, and that the Department of the
    Interior hold in abeyance the rest of the Nation’s application
    for the transfer of the Replacement Lands.
    On July 23, 2010, the Secretary determined that Parcel 2
    satisfied all the legal requirements of the Act, and that taking
    Parcel 2 into trust was mandatory. The Secretary adopted the
    position that, under Arizona law, the Replacement Lands are
    not part of the City because they are not within the City’s
    “corporate limits.” He expressly concluded that Parcel 2 is
    not “within the corporate limits of any city or town” based on
    the plain and jurisdictional meaning of “corporate limits”
    under the Act. The Secretary also agreed that the trust
    application concerning the remaining portions of the
    Replacement Lands would be held in abeyance, pending a
    new request by the Nation. The Secretary published notice of
    8     TOHONO O’ODHAM NATION V. STATE OF ARIZONA
    his decision on August 26, 2010. 75 Fed. Reg. 52,550. He
    was then permitted to take Parcel 2 into trust 30 days after
    publication of notice of his decision. See 25 C.F.R.
    § 151.12(b).
    IV.     Opposition and Litigation
    The Nation’s trust application and subsequent plans to
    build a gaming casino on Parcel 2 have been vigorously
    opposed by Defendants, the Gila River Indian Community,
    and others.
    Shortly after the Secretary’s July 2010 decision, the City,
    the Gila River Indian Community, and others filed lawsuits
    against the Department of the Interior in the District of
    Arizona, challenging the Parcel 2 decision as a violation of
    the Administrative Procedure Act and the U.S. Constitution.
    The Nation subsequently intervened as a defendant, and the
    State of Arizona and various state legislators intervened as
    plaintiffs.    The lawsuits were consolidated into one
    proceeding, denominated Gila River Indian Community v.
    United States, No. 10-cv-1993. In March 2011, the district
    court in Gila River Indian Community upheld the Secretary’s
    decision and rejected statutory and constitutional challenges
    brought by the City, the State of Arizona, and others. The
    plaintiffs in that case appealed. The district court enjoined
    the United States from taking Parcel 2 into trust and enjoined
    the City from annexing Parcel 2 during the pendency of the
    appeal.
    In an opinion issued on July 9, 2013, we affirmed the
    district court’s decision in part and reversed in part. See Gila
    River Indian Community v. United States, 
    729 F.3d 1139
    (9th
    Cir. 2013). We concluded that the phrase “within the
    TOHONO O’ODHAM NATION V. STATE OF ARIZONA               9
    corporate limits” under section 6(d) of the Act was
    ambiguous, and we instructed that the matter be remanded to
    the Secretary to reconsider the phrase in light of the
    ambiguity we identified. 
    Id. at 1147.
    Once our mandate
    issued, and the district court remanded Gila River Indian
    Community v. United States to the Secretary “consistent with
    the Ninth Circuit’s opinion and mandate,” it terminated the
    case, thereby dissolving its injunction.
    On June 21, 2013, we vacated submission of the present
    appeal pending the Secretary’s determination on remand. In
    response to our remand, on July 3, 2014, the Secretary
    reaffirmed that the phrase “within the corporate limits” has a
    jurisdictional rather than geographical meaning and was
    meant to describe “lands that have actually been incorporated
    by a municipality.” Applying this definition, the Secretary
    determined that Parcel 2 was not “within the corporate limits”
    of the City and that “the legal requirements under the Act for
    acquiring Parcel 2 in trust have been satisfied.” Consistent
    with the Secretary’s ruling, the United States took Parcel 2
    into trust for the Nation on July 7, 2014.
    V. H.B. 2534
    On February 1, 2011, while the district court proceedings
    in Gila River Indian Community were pending, the governor
    of Arizona signed H.B. 2534 into law. The bill was scheduled
    to take effect on July 20, 2011. A lead sponsor of H.B. 2534
    stated that the bill was made necessary by a “power grab by
    the federal government,” and that the legislature was
    “fighting an overreaching, intrusive Federal Government.”
    The bill, codified at A.R.S. § 9-471.04, provides as follows:
    10 TOHONO O’ODHAM NATION V. STATE OF ARIZONA
    A. Notwithstanding any other provision of
    this article:
    1. A city or town located in a county with a
    population of more than three hundred fifty
    thousand persons may annex any territory
    within an area that is surrounded by the city or
    town or that is bordered by the city or town on
    at least three sides if the landowner has
    submitted a request to the federal government
    to take ownership of the territory or hold the
    territory in trust.
    2. The annexation of territory pursuant to this
    section is valid if approved by a majority vote
    of the governing body of the city or town. The
    annexation becomes immediately operative if
    it is approved by at least two-thirds of the
    governing body of the city or town.
    B. For the purposes of this section, “submitted
    a request to the federal government” means
    the landowner has made an application to the
    federal government as required by a specific
    federal statute or regulation.
    A.R.S. § 9-471.04.
    VI.    Procedural History
    Shortly after passage of H.B. 2534, the Nation filed suit
    against Defendants. In the operative complaint, the Nation
    alleged that H.B. 2534 was specifically intended to frustrate
    the operation of the Act by permitting the City to annex the
    TOHONO O’ODHAM NATION V. STATE OF ARIZONA 11
    Nation’s land and bring it within the City’s “corporate
    limits,” thereby rendering that land ineligible to be taken into
    trust under the Act. The Nation alleges that H.B. 2534 is
    preempted by federal law, and is unconstitutional. In total,
    the Nation asserts six claims against Defendants: federal
    preemption (Count I); violation of the Due Process Clause
    under the U.S. and Arizona Constitutions (Counts II, V);
    violation of the Equal Protection Clause under the U.S. and
    Arizona Constitutions (Counts III, VI); and violation of the
    Arizona Constitution’s prohibition on special legislation
    (Count IV).
    The parties filed cross motions for summary judgment,
    which the district court granted in part and denied in part.
    Specifically, the district court ruled that H.B. 2534 directly
    conflicts with Congress’ intent that the Nation’s land be taken
    into trust pursuant to the Act, and is therefore preempted by
    the Act. The district court also determined that H.B. 2534 is
    preempted because it would cause the Nation to lose
    important voting and hearing opportunities that would
    otherwise be available under Arizona’s general annexation
    law, A.R.S. § 9-471, thereby impermissibly burdening a
    federal right. The district court denied the Nation’s due
    process claims because the Nation did not meet its burden of
    showing that H.B. 2534 is clearly arbitrary and unreasonable
    and unconnected to a legitimate state interest. It also denied
    the Nation’s equal protection claims finding that H.B. 2534
    survives the “very lenient” rational-basis inquiry. Finally, the
    district court held that the Nation has not shown beyond a
    reasonable doubt that H.B. 2534 constitutes special
    legislation.
    On June 30, 2011, the district court entered judgment in
    favor of the Nation on its preemption claim, declaring that
    12 TOHONO O’ODHAM NATION V. STATE OF ARIZONA
    H.B. 2534, as applied in this case, is preempted by the Act,
    and in favor of Defendants on the remaining claims. The
    parties timely filed cross appeals, which were consolidated.
    The judgment of the district court was not stayed pending this
    appeal.
    STANDARD OF REVIEW AND JURISDICTION
    “We review a district court’s legal determinations,
    including constitutional rulings, de novo.” Berger v. City of
    Seattle, 
    569 F.3d 1029
    , 1035 (9th Cir. 2009) (en banc). A
    district court’s grant or denial of summary judgment is also
    reviewed de novo. Wright v. Incline Vill. Gen. Improvement
    Dist., 
    665 F.3d 1128
    , 1133 (9th Cir. 2011).
    The district court may grant summary judgment on “each
    claim or defense – or the part of each claim or defense – on
    which summary judgment is sought.” Fed. R. Civ. P. 56(a).
    Summary judgment is proper where the pleadings, the
    discovery and disclosure materials on file, and any affidavits
    show that “there is no genuine dispute as to any material fact
    and the movant is entitled to judgment as a matter of law.”
    Id.; see also Celotex Corp. v. Catrett, 
    477 U.S. 317
    , 322
    (1986).
    ANALYSIS
    Defendants challenge the district court’s ruling that the
    Act preempts H.B. 2534. Congress’ power to preempt state
    law derives from the Supremacy Clause, which provides that
    the “Constitution, and the Laws of the United States . . . and
    all Treaties made, or which shall be made, under the
    Authority of the United States, shall be the supreme Law of
    the Land; . . . any Thing in the Constitution or Laws of any
    TOHONO O’ODHAM NATION V. STATE OF ARIZONA 13
    State to the Contrary notwithstanding.” U.S. Const. art. VI,
    cl. 2; see also Kurns v. R.R. Friction Products Corp., 132 S.
    Ct. 1261, 1265 (2012) (“Pre-emption of state law . . . occurs
    through the direct operation of the Supremacy Clause.”
    (quotation marks omitted)); Crosby v. Nat’l Foreign Trade
    Council, 
    530 U.S. 363
    , 372 (2000) (“A fundamental principle
    of the Constitution is that Congress has the power to preempt
    state law.”).
    There are three types of preemption: express, field, and
    conflict preemption. 
    Kurns, 132 S. Ct. at 1265
    –66. Conflict
    preemption consists of impossibility and obstacle preemption.
    
    Crosby, 530 U.S. at 372
    –73. In this case, the Nation asserts
    obstacle preemption. Obstacle preemption arises when a
    challenged state law “stands as an obstacle to the
    accomplishment and execution of the full purposes and
    objectives of Congress.” 
    Crosby, 530 U.S. at 373
    (quoting
    Hines v. Davidowitz, 
    312 U.S. 52
    , 67 (1941)).
    A. Presumption Against Preemption
    In conducting a preemption analysis, courts are guided by
    two bedrock principles: (1) the purpose of Congress, which
    is the “ultimate touchstone in every pre-emption case,” and
    (2) “the assumption that the historic police powers of the
    States were not to be superseded by the [f]ederal [a]ct unless
    that was the clear and manifest purpose of Congress.” Wyeth
    v. Levine, 
    555 U.S. 555
    , 565 (2009) (quotation marks
    omitted).1
    1
    The Supreme Court in United States v. Locke, 
    529 U.S. 89
    (2000),
    held that the presumption against preemption “is not triggered when the
    State regulates in an area where there has been a history of significant
    federal presence.” 
    Id. at 108.
    In UFO Chuting of Hawaii, Inc. v. Smith,
    14 TOHONO O’ODHAM NATION V. STATE OF ARIZONA
    Following Wyeth, the district court concluded that the
    presumption against preemption applies and, as a result, the
    Act preempts H.B. 2534 only if preemption was “the clear
    and manifest purpose of Congress.” 
    Wyeth, 555 U.S. at 565
    (quotation marks omitted). Although legislation related to
    Indian tribes is the exclusive province of Congress, H.B. 2534
    implicates a city’s authority to extend its corporate limits
    through annexation—an area of law historically subject to
    state regulation. See, e.g., Hussey v. City of Portland, 
    64 F.3d 1260
    , 1263 (9th Cir. 1995) (citing Hunter v. City of
    Pittsburgh, 
    207 U.S. 161
    , 178–79 (1907)).
    B. The Act Preempts H.B. 2534
    Despite the presumption against preemption, the district
    court properly concluded that H.B. 2534 is preempted by the
    Act. “What is a sufficient obstacle is a matter of judgment,
    to be informed by examining the federal statute as a whole
    and identifying its purpose and intended effects . . . .”
    
    Crosby, 530 U.S. at 373
    . As required by Crosby then, we
    proceed to examine the “purpose and intended effects” of the
    Act. The Act was passed in recognition of the federal
    government’s trust responsibility to the Nation and to
    compensate it for the destruction of tribal land by flooding.
    The Act recognized that “[t]he lack of an appropriate land
    base severely retards the economic self-sufficiency of the
    O’odham people of the Gila Bend Indian Reservation,
    contributes to their high unemployment and acute health
    problems, and result in chronic high costs for Federal services
    and transfer payments.” Pub. L. No. 99-503, § 2(3). As
    
    508 F.3d 1189
    (9th Cir. 2007), we distinguished Locke by limiting its
    holding to cases of field preemption, where “Congress leaves no room for
    state regulation.” 
    Id. at 1194–95.
        TOHONO O’ODHAM NATION V. STATE OF ARIZONA 15
    eponymously expressed by the “Gila Bend Indian
    Reservation Lands Replacement Act,” the Act was meant to
    “facilitate replacement of reservation lands with lands
    suitable for sustained economic use which is not principally
    farming and do not require Federal outlays for construction,
    and promote the economic self-sufficiency of the O’odham
    Indian people.” 
    Id. § 2(4).
    Under the Act, replacement land is to be obtained by
    enabling the Nation to purchase private land that, under
    certain conditions, the Secretary is to hold in trust for the
    Nation. Pub. L. No. 99-503, § 6(c)-(d). The Act describes
    the mechanism and requirements by which the federal
    government is to take purchased land into trust and thereby
    incorporate the land into tribal land:
    The Secretary, at the request of the Tribe,
    shall hold in trust for the benefit of the Tribe
    any land which the Tribe acquires pursuant to
    subsection (c) which meets the requirements
    of this subsection. Any land which the
    Secretary holds in trust shall be deemed to be
    a Federal Indian Reservation for all purposes.
    Land does not meet the requirements of this
    subsection if it is outside the counties of
    Maricopa, Pinal, and Pima, Arizona, or within
    the corporate limits of any city or town. Land
    meets the requirements of this subsection only
    if it constitutes not more than three separate
    areas consisting of contiguous tracts, at least
    one of which areas shall be contiguous to San
    Lucy Village. The Secretary may waive the
    requirements set forth in the preceding
    16 TOHONO O’ODHAM NATION V. STATE OF ARIZONA
    sentence if he determines that additional areas
    are appropriate.
    
    Id. § 6(d).
    Parsing this provision, several conditions must be
    satisfied before purchased land can be taken into trust by the
    Secretary. First, the phrase “at the request of the Tribe”
    indicates that the Nation must request that the Secretary take
    purchased land into trust. Second, the section imposes two
    limitations: (a) the purchased land cannot be “outside the
    counties of Maricopa, Pinal, and Pima” in Arizona, and (b)
    the purchased land cannot be “within the corporate limits of
    any city or town.” Third, the purchased land must
    “constitute[] not more than three separate areas consisting of
    contiguous tracts, at least one of which areas shall be
    contiguous to San Lucy Village.” Once these requirements
    are satisfied, the provision commands that the Secretary
    “shall” take the land into trust, and any such land “shall” be
    deemed to be tribal land. Thus, the Secretary’s taking of
    eligible land is mandatory, not permissive.
    Here, it is undisputed that the Nation purchased the 54
    acres of land constituting Parcel 2 and, on January 28, 2009,
    filed a trust application with the Secretary. It is also
    undisputed that the Secretary issued a decision on July 23,
    2010, concluding that Parcel 2 was not “within the corporate
    limits of any city or town,” and that, having satisfied all the
    legal requirements under the Gila Bend Act, acquisition of the
    land into trust was mandatory. Following our remand in Gila
    River Indian Community, 
    729 F.3d 1139
    (9th Cir. 2013), the
    Secretary has since reconsidered and reconfirmed the
    jurisdictional interpretation of the phrase “within the
    corporate limits.” But for the stay imposed by the district
    court in Gila River Indian Community pending appeal of that
    TOHONO O’ODHAM NATION V. STATE OF ARIZONA 17
    case, Parcel 2 could have been taken into trust after
    September 25, 2010.
    H.B. 2534 was passed two years after the Secretary’s
    decision was handed down. H.B. 2534 clearly stands as an
    obstacle to the implementation of the Act because, “under the
    circumstances of [this] particular case,” the effect of the state
    law is to thwart “the accomplishment and execution of the
    full purposes and objectives” of the Act—namely, to enable
    the Secretary to take Parcel 2 (and the remainder of the
    Replacement Lands) into trust and thereby incorporate the
    land into tribal land.

    (quotation
    marks omitted). Specifically, H.B. 2534 provides that “[a]
    city or town located in a county with a population of more
    than three hundred fifty thousand persons may annex any
    territory within an area that is surrounded by the city or town
    or that is bordered by the city or town on at least three sides
    if the landowner has submitted a request to the federal
    government to take ownership of the territory or hold the
    territory in trust.” A.R.S. § 9-471.04. This provision applies
    to the Replacement Lands because they are located within
    Maricopa County, which exceeds the population threshold of
    350,000 people,2 and are fully “surrounded” by lands
    incorporated by the City. Moreover, H.B. 2534 authorizes
    the annexation of adjacent lands—i.e., the placing of land
    within [the City’s] corporate limits—upon the landowner’s
    [the Nation’s] request that the land be taken into trust. This
    language in H.B. 2534 was triggered when the Nation
    requested that the Secretary take land purchased by the

    According to the U.S. Census Bureau, the estimated population of
    Maricopa County in 2011 was over 3 million. See U.S. Census Bureau,

    Nation [Parcel 2] into trust. Pub. L. No. 99-503, § 6(d). H.B.
    2534 further specifies that “‘submitted a request to the federal
    government’ means the landowner has made an application
    to the federal government as required by a specific federal
    statute or regulation.” The Act is such a “specific federal
    statute.” Accordingly, at the very moment the Nation files an
    application with the Secretary to take any of the Replacement
    Lands into trust, the City is permitted, pursuant to H.B. 2534,
    to annex the same land by either a majority vote of the
    governing body or by two-thirds vote of the governing body,
    in which case the annexation “becomes immediately
    operative.” A.R.S § 9-471.04, § A.2.
    It is abundantly clear that H.B. 2534 applies to the
    Nation’s trust application to the Secretary, filed in January
    2009, and would, if not preempted, enable the City to
    effectively veto any portion of that application not already
    brought to fruition. This is so because once the land is
    annexed, it would no longer be outside “the corporate limits”
    and therefore would be ineligible to be taken into trust. In
    this case, the Secretary has already determined that Parcel 2
    fulfills the statutory requirements of the Act and must be
    taken into trust, and took Parcel 2 into trust once the district
    court’s injunction in Gila River Indian Community was
    dissolved. The trust application for the remainder of the
    Replacement Lands has been held in abeyance, but if the
    Nation renews its application, the Secretary has an obligation
    to take it into trust, since it also satisfies the requirements
    under Section 6(d) of the Act. Unless preempted, H.B. 2534
    would permit the City to bar the taking of any of the
    remaining Replacement Lands into trust by the federal
    government, thereby blocking the Nation’s effort to find
    replacement land, all in direct contravention of the express
    purpose of the Act.
    TOHONO O’ODHAM NATION V. STATE OF ARIZONA 19
    Defendants challenge the district court’s preemption
    analysis primarily on the ground that the district court
    erroneously read a temporal freezing provision into Section
    6(d) of the Act. The district court interpreted the phrase “at
    the request of the Tribe” to mean that “when the Nation asks
    [the agency] to take land into trust that is not at that time
    within the corporate limits of any city or town, [the agency]
    has a mandatory obligation to take the land into trust provided
    the other requirements . . . are satisfied” (emphasis added).
    Section 6(d) does not specify a precise time at which the
    Secretary assesses whether the purchased land is or is not
    within corporate limits. The point in time could be at the
    time of purchase, at the time the trust application is filed, or
    anytime after the application is filed but before a decision by
    the Secretary is issued.
    However, we need not decide this issue, since it does not
    affect our preemption analysis. Under H.B. 2534, the City
    purportedly has the authority—at the point when the Nation
    files a trust application—to preemptively annex
    unincorporated land and effectively block the trust
    application. This directly bars the Nation’s effort to
    incorporate purchased land into tribal land, regardless of the
    moment in time at which the Secretary decides whether the
    land is within corporate limits. Under the circumstances of
    this case, H.B. 2534 stands as a clear and manifest obstacle to
    the purpose of the Act because it was enacted after the
    Nation’s trust application was filed, and it uses that
    application itself to thwart the taking of purchased land into
    trust. Accordingly, we hold that H.B. 2534 is preempted by
    the Act.
    20 TOHONO O’ODHAM NATION V. STATE OF ARIZONA
    CONCLUSION
    We affirm the decision of the district court. Because we
    hold that H.B. 2534 is invalid based on federal preemption,
    we need not reach the remaining challenges to H.B. 2534.
    The legality of the Secretary’s taking of Parcel 2 into trust
    pursuant to the Act is affirmed, and the Nation is free to
    petition the Secretary to have the remainder of the
    Replacement Lands taken into trust, pursuant to the Act.
    AFFIRMED.
