    SUMMARY**
    Indian Tribes
    The panel withdrew its prior opinion and published a
    superseding opinion affirming in part, and reversing and
    remanding in part, the district court’s summary judgment in
    favor of federal defendants in an action by the City of
    Glendale seeking to set aside the United States Department of
    Interior’s decision to accept in trust, for the benefit of the
    Tohono O’odham Nation, a 54-acre parcel of land known as
    Parcel 2 on which the Nation hoped to build a resort and
    casino.
    The panel held the Gila Bend Indian Reservation Lands
    Replacement Act, read as a whole, was unambiguous and that
    § 6(c) of the Act created a cap only on land held in trust for
    the Nation, not on total land acquisition by the tribe under the
    Act. The panel held that § 6(d) of Act was ambiguous as to

    whether Parcel 2, located on a county island fully surrounded
    by city land, was within the City of Glendale’s corporate
    limits. The panel held further that the Secretary of the
    Interior was mistaken in concluding that the term has a plain
    meaning, and remanded for the agency to consider the
    question afresh in light of the ambiguity the panel saw.
    Finally, the panel held that passage of the Act was within
    congressional power under the Indian Commerce Clause and
    was not trumped by the Tenth Amendment
    Judge N.R. Smith dissented. Judge Smith would hold that
    the statutory text of the Act clearly prohibits the Secretary’s
    ability to take land, that is “within the corporate limits” of a
    city, into trust when the city’s limits wholly surround that
    land, such as the parcel at issue in this case. Judge Smith
    would also hold that a remand to the agency is improper
    because the case should be resolved against the agency under
    step one of the Chevron analysis.

    OPINION
    McKEOWN, Circuit Judge:
    This case illustrates the nuances of our federalist system
    of government, pitting Indian tribe against Indian tribe, and
    State and local governments against the federal government
    and an Indian tribe. The City of Glendale and various other
    parties (“Glendale”) seek to set aside the Department of the
    Interior’s decision to accept in trust, for the benefit of the
    Tohono O’odham Nation (“the Nation”), a 54-acre parcel of
    land known as Parcel 2. The Nation hopes to build a
    destination resort and casino on Parcel 2, which is
    unincorporated county land, entirely surrounded by the City
    of Glendale. To say this plan has been controversial is an
    understatement. But the strong feelings and emotional drama
    of the casino fight do not dictate the outcome here. This
    appeal relates only to the status of the land as trust land and
    does not involve the particulars of Indian gaming, which are
    the subject of separate proceedings and pending legislation.
    The district court granted summary judgment for the
    government after concluding that the Secretary of the Interior
    reasonably applied the Gila Bend Indian Reservation Lands
    Replacement Act (“Gila Bend Act”), and that the Act did not
    violate the Indian Commerce Clause or the Tenth
    Amendment. We affirm in part, reverse in part, and remand.
    GILA RIVER INDIAN CMTY . V . UNITED STATES            11
    BACKGROUND
    I. THE GILA BEND ACT
    The Nation, earlier known as the Papago Tribe of
    Arizona, is a federally recognized Indian Tribe with over
    28,000 members. The Gila Bend Reservation was established
    as early as 1882. Today, the reservation includes non-
    contiguous land located near Tucson, Phoenix, and the town
    of Gila Bend, as well as points in between. In 1960, the
    federal government completed construction of the Painted
    Rock Dam ten miles downstream from the Gila Bend
    Reservation. During the late 1970s and early 1980s, the
    reservation was plagued by flooding from the dam, which
    eventually destroyed a large farm developed by the Nation,
    leaving the land unsuitable for economic use.
    Congress responded to the flooding and the Nation’s
    petition for a new reservation with the Gila Bend Act. The
    purpose of the Act was to “facilitate replacement of
    reservation lands with lands suitable for sustained economic
    use which is not principally farming . . . and promote the
    economic self-sufficiency of” the Nation. Pub. L. No. 99-
    503, 
    100 Stat. 1798
    , § 2(4). Under § 4 of the Act, the Nation
    transferred 9,880 acres of reservation land to the United
    States in return for $30 million and the right to replace the
    lost reservation acre-for-acre. Id. at §§ 4(a), 6(c). Subject to
    the requirements and limitations of the Act, the Secretary of
    the Interior is required to take up to 9,880 acres of land into
    trust for the benefit of the Nation, effectively making the land
    part of the Nation’s reservation. Id. at § 6(d).
    The Act permits the Nation to use the funds for various
    purposes, including the purchase of land, and economic and
    12        GILA RIVER INDIAN CMTY . V . UNITED STATES
    community development. § 6(a).1 Section 6(c) imposes an
    acreage limit.2 Section 6(d) establishes that trust land refers
    to land under subsection (c), and that such land cannot be
    taken into trust as reservation land if it is (i) outside certain
    counties, or (ii) “within the corporate limits of any city or
    town.”3
    Over the decades after passage of the Act, the Nation
    acquired land in Arizona but only one parcel has been taken
    into trust. Then, in 2003, the Nation purchased the disputed
    land as part of a 135-acre acquisition. The land is a “county
    island,” surrounded entirely by the City of Glendale. A
    county island is unincorporated land surrounded entirely by
    lands incorporated by the municipality. See Town of Gilbert
    v. Maricopa Cnty., 
    141 P.3d 416
    , 418 n.1 (Ariz. Ct. App.
    2006) (describing county island).

    “The Tribe shall invest sums received under section 4 in interest
    bearing deposits and securities until expended. The . . . [Nation] may
    spend the principal and the interest and dividends accruing on such sums
    . . . for land and water rights acquisition, economic and community
    development, and relocation costs.” § 6(a).
    2
    “The Tribe is authorized to acquire by purchase private lands in an
    amount not to exceed, in the aggregate, nine thousand eight hundred and
    eighty acres.” § 6(c).
    3
    “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.” § 6(d).
    GILA RIVER INDIAN CMTY . V . UNITED STATES                       13
    In 2009, the Nation announced plans to use the land for
    gaming purposes and filed an application with the
    Department of the Interior to have the land held in trust under
    the Gila Bend Act. In response, the City of Glendale sought
    to annex a portion of the 135 acres. The Nation filed suit in
    state court challenging the annexation effort.4 Due to
    ongoing state litigation, without relinquishing its claim to the
    full 135 acres, the Nation requested that the Department of
    the Interior accept into trust only a 54-acre portion of the land
    not at issue in state court: Parcel 2, the subject of this
    appeal.5
    II. PRIOR PROCEEDINGS AND DECISIONS
    Although the Department of the Interior treated the
    Nation’s trust application as an ex parte filing, in March
    2009, both the City of Glendale and the Gila River Indian
    4
    The Nation ultimately prevailed on appeal. See Tohono O’odham
    Nation v. City of Glendale, 
    253 P.3d 632
     (Ariz. Ct. App. 2011), petition
    for review denied Oct. 25, 2011.
    5
    The dissent recounts various facts at length to provide, in its view, “the
    rest of the story.” In effect, the dissent along with the parties opposing the
    trust designation, infuse the appeal with the Nation’s economic motives
    and plans for Indian gaming on the trust land. But those issues are not on
    appeal. W e do not and are not called upon to express an opinion as to the
    availability of the trust land for use as a casino. That question is tied up
    in other litigation and the legislation that recently passed the House of
    Representatives. See Gila Bend Indian Reservation Lands Replacement
    Clarification Act. H.R. R EP . No. 112-440 (2012). This issue does not bear
    on our interpretation of the Gila Bend Act.
    14      GILA RIVER INDIAN CMTY . V . UNITED STATES
    Community6 filed lengthy submissions opposing the trust
    application. Their submissions argued that Parcel 2 fell
    “within the corporate limits” of the City of Glendale and was
    therefore ineligible for trust status under § 6(d) of the Gila
    Bend Act.
    The Secretary of the Interior concluded that the
    requirements of the Gila Bend Act were met. Specifically,
    Parcel 2 is wholly within Maricopa County and is outside the
    City of Glendale’s corporate limits. In considering whether
    the land qualified for trust status under § 6(d), the Secretary
    explained that “[t]he Western Regional Director of the BIA
    [Bureau of Indian Affairs], acting under authority of the
    Secretary, issued a waiver under Section 6(d) . . . that allowed
    the Nation to purchase up to five (5) separate areas of
    replacement land, rather than three, and further waived the
    requirement that one of these areas be contiguous to the San
    Lucy reservation.” In any event, since Parcel 2 is only the
    second replacement land area to be held in trust under the
    Act, those waivers do not directly implicate the analysis here.
    Thus, in accord with the mandate of the Act, the Secretary
    determined that Parcel 2 must be held in trust for the Nation.
    In upholding the Secretary of the Interior’s decision, in a
    careful, comprehensive opinion, the district court concluded
    that Glendale had waived its argument regarding a total
    acreage cap under § 6(c) of the Act, because it failed to raise
    6
    The Gila River Indian Community is a separate tribe whose gaming
    interests are implicated by the Nation’s plans to develop a casino on
    Parcel 2.
    GILA RIVER INDIAN CMTY . V . UNITED STATES                  15
    the issue in the administrative proceeding.7 The district court
    then deemed the statutory language “within the corporate
    limits” in § 6(d) to be ambiguous as to county islands like
    Parcel 2, and concluded that Arizona law was inconclusive.
    Applying Chevron, the court deferred to the agency’s
    interpretation of the statute and affirmed the trust decision as
    “based on a permissible construction of the statute.” See
    Chevron, U.S.A., Inc. v. Natural Res. Defense Council, Inc.,
    
    467 U.S. 837
    , 843 (1984). Finally, the district court rejected
    the constitutional arguments under the Tenth Amendment and
    the Indian Commerce Clause.
    “We review the grant of summary judgment de novo, thus
    reviewing directly the agency’s action under the
    Administrative Procedure Act’s (APA) arbitrary and
    capricious standard.” Gifford Pinchot Task Force v. U.S.
    Fish & Wildlife Serv., 
    378 F.3d 1059
    , 1065 (9th Cir. 2004).
    ANALYSIS
    We first consider two questions of statutory
    interpretation: Whether the Gila Bend Act’s trust land
    acreage limit is implicated, and whether Parcel 2 is “within”
    the corporate limits of the City of Glendale. We evaluate an
    agency’s interpretation of a statute it is entrusted to
    administer by first determining “whether Congress has
    directly spoken to the precise question at issue.” Chevron,
    
    467 U.S. at 842
    . If Congress has directly spoken, “the agency
    (and the court) must give effect to Congress’s clearly
    7
    W e note that, according to the Secretary, the normal “notice and
    comment provisions of 
    25 C.F.R. §§ 151.10
     and 151.11(d), requiring that
    the BIA notify state and local governments of the land-into-trust
    application, are not applicable” to this transaction.
    16      GILA RIVER INDIAN CMTY . V . UNITED STATES
    expressed intent.” Adams v. U.S. Forest Serv., 
    671 F.3d 1138
    , 1143 (9th Cir. 2012). If, on the other hand, a statute is
    ambiguous, we defer to the agency’s interpretation where the
    “interpretation was ‘a reasonable policy choice for the agency
    to make.’” 
    Id.
     (quoting Chevron, 
    467 U.S. at 845
    ).
    The remaining issues pertain to the limits of
    congressional power under the Indian Commerce Clause and
    the Tenth Amendment.8
    I. THE ACREAGE LIMIT IN SECTION 6(C )
    Section 6(c) of the Gila Bend Act provides that the Nation
    “is authorized to acquire by purchase private lands in an
    amount not to exceed, in the aggregate, 9,880 acres.” In turn,
    the following subsection, 6(d), describes trust land as being
    land acquired “pursuant to subsection (c).” Before the district
    court, Glendale argued for the first time that § 6(c) precludes
    the Nation from acquiring more than 9,880 acres with money
    from the Act and that the Nation already had exceeded that
    acreage cap before acquiring Parcel 2. The Nation responds
    that the cap only applies to land held in trust via § 6(d), and
    not to land remaining in fee status.
    While the Secretary of the Interior did not squarely
    consider the acreage cap because the issue was never framed
    as a barrier to taking Parcel 2 in trust, reading the Secretary’s
    decision in context is telling. In determining whether the
    § 6(d) trustee requirements were met, the Secretary read the
    8
    The Gila River Indian Community and the Terry and Rios appellants
    appeal as to all issues except the Indian Commerce Clause and the Tenth
    Amendment. The City of Glendale and the various Arizona appellants
    (collectively “Arizona appellants”) appeal as to all of the issues.
    GILA RIVER INDIAN CMTY . V . UNITED STATES            17
    statute as creating a cap on land that could be held in trust
    under the Gila Bend Act, not as a cap on the total acreage that
    the Nation could acquire. The Secretary explained the basis
    of this reading, noting that “[t]he first, and so far only, land
    acquired in trust for the Nation” was 3,200.53 acres acquired
    in September 2004. The decision goes on to state that there
    was another trust application for 3,759.52 acres but that the
    land was still held in fee. Therefore, the Secretary did not
    consider land held in fee as relevant to the analysis of the
    acquisition limitations under the Gila Bend Act. The decision
    explicitly counts only the fee-to-trust lands, not lands
    remaining in fee status.
    During agency proceedings, the Gila River Indian
    Community, one of the parties now raising the acreage cap
    argument, noted, in contrast to its current position, that
    “[s]ection 6(c) limits the number of acres that may be placed
    into trust to no more than 9,880 acres.” Appellants, including
    the Gila River Indian Community, now take the opposite
    position and argue that because the agency proceedings were
    non-adversarial, the issue should be considered on the merits.
    The Nation and the government maintain that the acreage cap
    argument was waived. The ultimate question is one of
    statutory construction.
    Assuming, without deciding, that the argument was not
    waived, we hold that the statute read as a whole is
    unambiguous and that § 6(c) creates a cap only on land held
    in trust for the Nation, not on total land acquisition by the
    tribe under the Act.
    Our goal is to understand the statute “as a symmetrical
    and coherent regulatory scheme” and to “fit, if possible, all
    parts into a harmonious whole.” FDA v. Brown & Williamson
    18     GILA RIVER INDIAN CMTY . V . UNITED STATES
    Tobacco Corp., 
    529 U.S. 120
    , 133 (2000) (citations omitted).
    Section 6(a) authorizes the Nation to use funds received
    under the Gila Bend Act “for land and water rights
    acquisition, economic and community development, and
    relocation costs.” This authorization is broader than land
    acquisition and does not address trust acreage to replace the
    Nation’s lost reservation land.
    Apart from the general provisions of § 6(a), three
    provisions of the Act concern the divestment and replacement
    of reservation land. Section 4 concerns the original
    9,880-acre reservation, and specifies the conditions under
    which the Nation would forfeit its “right, title, and interest . . .
    in nine thousand eight hundred and eighty acres of
    [reservation] land.” Subsections 6(c) and 6(d) provide for the
    replacement of this precise number of acres of reservation
    land. Section 6(d) explains the mechanism for restoring
    reservation land, which requires placing land in trust, and
    limits the location of reservation land. More specifically,
    § 6(d) provides:
    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.
    Section 6(c), in turn, limits the size of newly acquired trust
    land to that of the previous reservation: 9,880 acres. Thus,
    § 6(c) imposes a limit upon the size of land placed in trust for
    reservation purposes, under § 6(d), rather than upon total land
    GILA RIVER INDIAN CMTY . V . UNITED STATES            19
    acquisition under § 6(a). Subsection 6(c) and 6(d) are
    internally cross-referenced and must be read together.
    Aside from its inapplicability to non-reservation land,
    treating § 6(c) as a limit on land acquired under § 6(a) is
    problematic for other reasons. Congress crafted the Gila
    Bend Act to allow the Nation substantial autonomy in the use
    of funds and the acquisition of new reservation land. Because
    Congress did not expect the Nation to spend the Gila Bend
    Act funds immediately or all at once, Congress provided that
    the funds be invested in “interest bearing deposits and
    securities until expended.” § 6(a). This requirement
    underscores that Congress did not intend for the tribe to spend
    a fixed dollar amount, or to spend a specific amount on land,
    or to acquire the land at any particular time. Rather, the
    Nation was to have broad discretion in the use of Gila Bend
    Act funds, and the yield on those funds. The ability to buy
    land without regard to the cap on trust acreage and then
    designate the parcels for conversion to trust is well within the
    “great flexibility” Congress authorized for the Nation. See
    H.R. Rep. No. 99-851, at 10 (1986) (envisioning the Nation
    to “have great flexibility in determining the use of funds
    provided under the Act.”).
    Of course, the Nation does not need statutory
    authorization to acquire and hold land in fee simple. The
    Nation has the right to buy and sell land just like other
    persons or entities. See Cohen’s Handbook of Federal Indian
    Law § 15.04 (describing various forms of tribal land
    acquisition, including the purchase of fee simple title).
    Glendale’s reading would mean that the Gila Bend Act
    purported to curtail the Nation’s independent right to buy and
    sell land, an outcome we do not endorse and one that is
    inconsistent with decades of Indian law.
    20     GILA RIVER INDIAN CMTY . V . UNITED STATES
    Further, § 6(b) relieves the Secretary of any audit or
    oversight responsibility for expenditure of funds under § 6(a):
    “The Secretary [of the Interior] shall not be responsible for
    the review, approval, or audit of the use and expenditure” of
    the replacement land funds. § 6(b). If § 6(a) were cabined by
    § 6(c), the Secretary would necessarily undertake a
    monitoring function as to expenditure of money for trust
    lands, a responsibility specifically disclaimed by the Act.
    Finally, as a practical matter, even Glendale’s
    interpretation would permit the Secretary to accept Parcel 2
    in trust. This argument boils down to the view that the first
    9,880 acres acquired must go into trust. Nothing in the Act
    specifies that the lands must go into trust in a chronological
    order pegged to the time of acquisition. There is no FIFO
    (first in, first out) principle incorporated in the Act. The Act
    allows the Nation to replace, acre-for-acre, the 9,880 acres of
    reservation land it relinquished to federal control under
    § 4(a). To date, the Secretary of the Interior has taken just
    one parcel into trust for the Nation, an approximately 3,200-
    acre parcel known as San Lucy Farms. Acquisition in trust of
    the 54 acres in Parcel 2 would be the Nation’s second trust
    acquisition and, after acquisition, the Nation would remain
    well below the 9,880-acre cap on trust land. That the Nation
    may have purchased other land is irrelevant to the clear
    limitation that only 9,880 acres may be held in trust.
    II. THE CORPORATE LIMITS RESTRICTION               IN   SECTION
    6(D )
    Section 6(d) of the Gila Bend Act prohibits the Secretary
    of the Interior from taking land into trust “if it is outside the
    counties of Maricopa, Pinal, and Pima, Arizona, or within the
    corporate limits of any city or town.” (emphasis added). It
    GILA RIVER INDIAN CMTY . V . UNITED STATES                      21
    is undisputed that Parcel 2 is in Maricopa county; the issue is
    whether Parcel 2, located on a county island fully surrounded
    by city land, is within the City of Glendale’s corporate limits.
    The Secretary, invoking plain meaning, interpreted the
    phrase “within the corporate limits” as “show[ing] a clear
    intent to make a given piece of property eligible under the
    Act if it is on the unincorporated side of a city’s boundary
    line,” and concluded Parcel 2 therefore could be taken into
    trust. Similarly, the government and the Nation argue for a
    jurisdictional meaning: Any land not subject to a city’s
    corporate jurisdiction is not “within” the city.9 The Arizona
    appellants contend the phrase should have a geographical
    meaning: Any land entirely surrounded by a city’s corporate
    limits is “within” the city. Who knew that such a
    straightforward sounding phrase, “within the corporate
    limits,” could generate such competing views.
    As explained below, we conclude the statute is
    ambiguous. The Secretary’s decision reflects a failure to
    grapple with the ambiguity and prompts us to remand for the
    Secretary to bring his expertise to bear to interpret the
    provision anew. See Negusie v. Holder, 
    555 U.S. 511
    , 523
    (2009) (“[I]f an agency erroneously contends that Congress’
    intent has been clearly expressed and has rested on that
    ground, we remand to require the agency to consider the
    question afresh in light of the ambiguity we see.”) (internal
    quotation marks omitted).
    9
    The dissent’s suggestion that the government took a differing view in
    prior litigation is not borne out by the record. In totally unrelated
    litigation, the government made passing reference to geographical
    restrictions on trust land. But, in doing so, the brief did not consider the
    distinction under § 6(d) nor was this section at issue in the litigation.
    22     GILA RIVER INDIAN CMTY . V . UNITED STATES
    The Department of the Interior’s treatment of the
    provision is telling. The Department’s Office of the Solicitor
    prepared a memorandum for the Secretary on the meaning of
    “corporate limits” and concluded the term was ambiguous.
    The Field Solicitor, considering submissions from both the
    Nation and the City, explained: “A close review of the
    statutes and case law of the State of Arizona reveals that this
    question has no clear or dispositive answer, and that there is
    ambiguity about it, even to the point of one of the Justices of
    the Arizona Supreme Court admitting as much.” Although
    the Field Solicitor was inclined to accord the term a
    jurisdictional meaning in reliance on Speros v. Yu, 
    83 P.3d 1094
     (Ariz. Ct. App. 2004), he emphasized that such a
    position was “reached with some degree of caution, since the
    concepts of ‘exterior boundaries’ and ‘corporate limits’ are
    neither expressly defined nor used with any real consistency
    under Arizona law.” Ultimately, the Field Solicitor
    determined that to resolve the inconsistency he was “obliged
    to invoke the rule regarding canons of construction regarding
    Federal Indian law and Indian jurisprudence,” which counsels
    that ambiguous statutes are to be construed in favor of
    Indians. See Cnty. of Yakima v. Confederated Tribes and
    Bands of Yakima Nation, 
    502 U.S. 251
    , 269 (1992).
    Applying that canon, the Field Solicitor interpreted the term
    to have a jurisdictional meaning.
    In the trust decision, the Secretary referenced but parted
    ways with the Field Solicitor’s report and concluded that the
    term “corporate limits” was not ambiguous. The Secretary
    determined the term had the plain meaning of indicating the
    jurisdictional status of fee land: “The use of ‘corporate limits’
    shows a clear intent to make a given piece of property
    eligible under the [Gila Bend] Act if it is on the
    unincorporated side of the city’s boundary line.” (emphasis
    GILA RIVER INDIAN CMTY . V . UNITED STATES                       23
    added). The Secretary reasoned that, had Congress intended
    to exclude county islands from possible trust acquisition, it
    could have done so by using language such as “exterior
    boundary,” “within one mile of any city” or “city limits.”
    See, e.g., 
    16 U.S.C. § 485
     (Secretary of Agriculture may
    accept “title to any lands within the exterior boundaries of the
    national forests”); 
    25 U.S.C. § 465
     (certain funds may not be
    “used to acquire additional land outside of the exterior
    boundaries of Navajo Indian Reservation”). In a footnote of
    the trust decision, the Secretary added, in the alternative, that
    “[e]ven if Congress’s intent was less clear. . . we interpret the
    term not to support a conclusion that Parcel 2 is ineligible
    under the Act, with or without consideration of the [Indian]
    canon.”
    We hold that the Secretary was mistaken in concluding
    that the term has a plain meaning.10 Giving the key phrase
    “within the corporate limits” its plain, natural, and common
    meaning does not resolve the ambiguity. United States v.
    Romo-Romo, 
    246 F.3d 1272
    , 1275 (9th Cir. 2001) (“[W]e
    should usually give words their plain, natural, ordinary and
    commonly understood meanings.”). Here, either reading of
    the term as used in the statute is plausible. Further, we agree
    with the Field Solicitor’s conclusion that Arizona law does
    not conclusively solve the dilemma.
    The history of Arizona’s treatment of county islands
    underscores the lack of uniformity of interpretation and
    uncertainty that carries over to the Gila Bend Act’s use of the
    10
    Curiously, the dissent takes the view that the text of § 6(d) has a plain
    meaning but then surprisingly comes to an interpretation at odds with the
    Secretary. Even the division within our panel underscores the lack of
    clarity in the statute.
    24     GILA RIVER INDIAN CMTY . V . UNITED STATES
    “within the corporate limits” designation. In past ordinances,
    the City of Glendale has characterized county islands as lying
    outside its corporate limits and requiring annexation to be
    included within the City’s limits. For example, when the City
    of Glendale incorporated a strip of land that surrounds Parcel
    2 and other unincorporated territory, the annexation ordinance
    provided that “the present corporate limits [are] extended and
    increased to include” only the strip of land precisely
    described with metes and bounds. City of Glendale, AZ,
    Ordinance 986 New Series, (July 26, 1977). Similarly,
    numerous City of Glendale annexation ordinances address
    land “located within an existing county island” and confirm
    that as a result of the annexation, the newly annexed county
    island will “be included within the corporate limits of the
    City of Glendale.” See, e.g., City of Glendale, AZ, Ordinance
    2693 New Series, (Sept. 23, 2009); City of Glendale, AZ,
    Ordinance 2674 New Series, (Mar. 18, 2009); City of
    Glendale, AZ, Ordinance 2668 New Series, (Mar. 11, 2009).
    Some Arizona statutes also refer to county islands as falling
    outside corporate limits. See, e.g., 
    Ariz. Rev. Stat. Ann. § 9
    -
    500.23 (authorizing a city to “provide fire and emergency
    medical services outside its corporate limits to a county
    island”). However, Arizona statutes do not explicitly define
    the term and Arizona courts have used “corporate limits” and
    “exterior boundaries” interchangeably. See, e.g., Flagstaff
    Vending Co. v. City of Flagstaff, 
    578 P.2d 985
    , 987 (Ariz.
    1978) (holding that a state-owned university campus was
    “within” city limits for purposes of local tax ordinances).
    Having resolved that the statute is ambiguous, the
    question is how to treat the Secretary’s decision under
    Chevron. We conclude that the Secretary’s interpretation
    warrants no deference because it rests on a mistaken
    conclusion that the language has a plain meaning.
    GILA RIVER INDIAN CMTY . V . UNITED STATES          25
    Were the statute clear, we would simply “stop the music
    at step one,” as we did with § 6(c), supra, in order to “give
    effect to [Congress’s] unambiguously expressed intent.”
    Northpoint Tech., Ltd. v. FCC, 
    412 F.3d 145
    , 151 (D.C. Cir.
    2005) (internal quotation marks omitted). Here, we must
    move to step two because Congress’s intent is not clear. At
    this stage, normally we would defer as a matter of course to
    the agency’s expertise and discretion in interpreting the
    statute. However, because the agency misapprehended the
    clarity of the statute, such deference is not in order.
    “[D]eference to an agency’s interpretation of a statute is not
    appropriate when the agency wrongly ‘believes that
    interpretation is compelled by Congress.’” PDK Labs. Inc. v.
    DEA, 
    362 F.3d 786
    , 798 (D.C. Cir. 2004) (quoting Arizona v.
    Thompson, 
    281 F.3d 248
    , 254 (D.C. Cir. 2002)).
    The principle that Chevron deference does not apply
    where an agency mistakenly determines that its interpretation
    is mandated by plain meaning, or some other binding rule, is
    best illustrated by the Supreme Court’s decision in Negusie.
    There, the Court declined to uphold the BIA’s interpretation
    of an ambiguous provision of the Immigration and
    Nationality Act where the BIA mistakenly thought itself
    bound by Supreme Court precedent construing similar
    language in a different statute. Negusie, 
    555 U.S. at
    518–19.
    Although the Court explained that the chosen interpretation
    might ultimately be reasonable, it declined to apply Chevron
    deference and remanded because the agency “deemed its
    interpretation to be mandated by [precedent], and that error
    prevented it from a full consideration of the statutory
    26      GILA RIVER INDIAN CMTY . V . UNITED STATES
    question here presented.” 
    Id. at 521
     (emphasis added);11 see
    also Delgado v. Holder, 
    648 F.3d 1095
    , 1103 & n.12 (9th Cir.
    2011) (en banc) (upholding BIA interpretation of ambiguous
    statute despite its reliance on plain text because the BIA’s
    decision “did not rely on plain text alone” but also
    “emphasized that its interpretation is supported by the history
    and background” of the statute) (internal quotation marks
    omitted).
    The present case has a twist that bears further
    consideration. Unlike in Negusie, the agency here did not rest
    entirely on the purportedly clear congressional intent, but
    added that it would reach the same conclusion “[e]ven if
    Congress’s intent was less clear.” This one-sentence caveat
    in a footnote is not entitled to Chevron deference, because the
    Secretary did not provide any explanation for this decision.
    In short, the passing footnote reflects “that the [Department
    of the Interior] has not yet exercised its Chevron discretion to
    interpret the statute in question” and thus “the proper
    course . . . is to remand to the agency for additional
    investigation or explanation.” Negusie, 
    555 U.S. at 523
    (internal question marks omitted).
    The essence of Chevron deference at step two is to give
    meaning to the “delegation[] of authority to the agency to fill
    the statutory gap in reasonable fashion” through resolution of
    “difficult policy choices that agencies are better equipped to
    11
    The Nation and the government view Negusie as inapposite because
    the Secretary here only believed himself bound by plain meaning rather
    than by precedent. This is a distinction without a difference. If the
    agency fails to bring its expertise to bear because it believes itself
    constrained for whatever reason from fully considering policy and
    practical considerations, the rationale for Chevron— agency expertise— is
    absent.

    545 U.S. 967
    , 980 (2005). Without

    know whether the agency employed its expertise or “simply
    pick[ed] a permissible interpretation out of a hat.” Vill. of
    Barrington v. Surface Transp. Bd.,

    Chevron step two “only if the agency has offered a reasoned
    explanation for why it chose that interpretation” judged
    according to “only the rationales the [agency] actually offered
    in its decision”) (emphasis added); see also Local Union

    “plain” because the court concluded that the agency’s
    decision “adequately stated the practical and policy
    considerations ultimately motivating its interpretation”)
    (emphasis added).
    The Secretary’s discussion focuses on why the statutory
    text is clear and does not articulate any other factors
    counseling in favor of adopting the alternative position
    dropped into the footnote. The government argues that the
    Field Solicitor’s report suffices to show that the Secretary
    grappled with the ambiguity of the statute. But the
    Secretary’s decision merely referenced the Field Solicitor’s
    determination that (some) Arizona law supports the
    conclusion that Parcel 2 is not within the corporate limits in
    support of the proposition that the statutory text was plain.
    The Secretary’s decision goes out of its way to disclaim the
    ambiguity that the Field Solicitor highlighted, asserting
    repeatedly that the meaning is “plain” and that the language
    shows a “clear intent” to adopt a jurisdictional meaning. The
    28      GILA RIVER INDIAN CMTY . V . UNITED STATES
    Secretary declined to consider the impact of the Indian
    canon—even though the Field Solicitor concluded application
    of the canon was necessary because Arizona law was too
    unsettled on the issue to yield a straightforward answer—and
    mentioned no policy or practical concerns.
    The Supreme Court has explained that, although the
    “scope of review under the arbitrary and capricious standard
    is narrow,” “the agency must . . . articulate a satisfactory
    explanation for its action.” Motor Veh. Mfrs. Ass’n v. State
    Farm Mutual Auto. Ins. Co., 
    463 U.S. 29
    , 43 (1983) (internal

    deferring to the Secretary’s unexplained caveat would permit
    the agency to sidestep its duty to bring its expertise to bear on
    the “difficult policy choices” it is tasked with making.

    Aside from the issue of Chevron deference, the Nation argues that the
    Department of the Interior’s trust decision is compelled by the Indian
    canon’s requirement that when there is doubt as to the proper
    interpretation of an ambiguous provision in a federal statute enacted for
    the benefit of an Indian tribe, “the doubt [will] benefit the Tribe.”

    We are puzzled by the dissent’s invocation of the clear
    statement or “federalism” canon. The clear statement rule,
    which is a canon of statutory construction, not a rule of
    constitutional law, applies where courts “confront[] a statute
    susceptible of two plausible interpretations, one of which . . .
    alter[s] the existing balance of federal and state powers.”
    Salinas v. United States, 
    522 U.S. 52
    , 59 (1997); see also
    Hilton v. South Carolina Pub. Rys. Comm’n, 
    502 U.S. 197
    ,
    205–06 (1991) (distinguishing between a rule of
    constitutional law and a rule of statutory construction and
    using the plain statement rule as an example of a rule of
    statutory construction). The rule counsels that “absent a clear
    indication of Congress’ intent to change the balance, the
    proper course [is] to adopt a construction which maintains the
    existing balance.” Salinas, 
    522 U.S. at 59

    (quoting Artichoke Joe’s Cal. Grand Casino v. Norton, 
    353 F.3d 712
    , 729
    (9th Cir. 2003)). The Gila River Indian Community counters that the
    canon is inapplicable when there are competing tribal interests.
    If by application of canons, or other “traditional tools of statutory
    construction,” we could “ascertain[] that Congress had an intention on the
    precise question at issue,” we would resolve the ambiguity at step one.
    Chevron, 
    467 U.S. at
    843 n.9. However, the application of the Indian
    canon in these circumstances is unsettled. W e therefore leave it to the
    Secretary to consider application of the Indian canon, and other relevant
    canons of statutory construction, in the first instance on remand. “The
    canons of construction applicable in Indian law are rooted in the unique
    trust relationship between the United States and the Indians.” Oneida
    County v. Oneida Indian Nation, 
    470 U.S. 226
    , 247 (1985). The Secretary
    is best positioned to take stock initially of whether and how to weigh the
    competing interests. At this stage, the job of considering the statutory
    ambiguity in light of the conflicting interests “is not a task we ought to
    undertake on the agency’s behalf.” Dep’t of Treasury, IRS v. Fed. Labor
    Relations Auth.,

    30      GILA RIVER INDIAN CMTY . V . UNITED STATES
    To begin, in the nine briefs filed with the court, it is no
    surprise that not a single brief referenced this argument.13 It
    is also telling that no party argued that the Secretary’s
    construction of § 6(d), in particular, raised serious
    constitutional problems or implicated state sovereignty. The
    Arizona appellants’ effort at oral argument to reframe the rule
    to one of constitutional avoidance is unavailing because
    § 6(d) does not implicate constitutional sovereignty concerns.
    Not only is this recharacterization of the claim an eleventh
    hour effort to change gears, but this canon of construction
    does not bear on our interpretation of the Gila Bend Act.
    Neither the dissent nor the Arizona appellants have
    articulated a state sovereignty or constitutional interest vis-a-
    vis § 6(d). Whatever our interpretation of the phrase “within
    the corporate limits of any city or town,” it does not raise a
    question of federal encroachment on state power. In short,
    the Gila Bend Act does not implicate an “existing balance of
    federal and state powers.” In Gregory v. Ashcroft, 
    501 U.S. 452
     (1991), the Court does not indicate that the clear
    statement rule applies to any and all regulation of state
    governmental functions. Justice White, in his partial
    concurrence, partial dissent in Gregory raises this issue
    explicitly: “The majority’s approach is also unsound because
    it will serve only to confuse the law. First, the majority fails
    to explain the scope of its rule. . . . Second, the majority does
    not explain its requirement that Congress’ intent to regulate
    a particular state activity be ‘plain to anyone reading [the
    federal statute].’” 
    Id. at 478
    . Virtually any federal legislation
    could be construed to have at least minor, derivative
    implications for traditional state functions. For example,
    13
    In an order from the panel after briefing and just before argument, the
    parties were asked to discuss the clear statement rule at oral argument.
    GILA RIVER INDIAN CMTY . V . UNITED STATES                       31
    does federal legislation appropriating funds for building and
    maintaining interstate highways require a plain statement of
    congressional intent to interfere with the traditional state
    functions of zoning and land use that the dissent flags in this
    case? The plain statement rule should not be applied in a way
    that makes it into a useless tautology.
    To the extent one is searching for a clear statement,
    Congress was clear: The Nation is entitled to swap out 9,880
    acres of trust land ceded to the federal government for land of
    equivalent total acreage. This swap does not implicate state
    interests nor can the Arizona appellants seriously argue that
    state sovereign interests restrict the Secretary from
    establishing a reservation on trust land.14 As we know,
    “[s]tate sovereignty does not end at a reservation’s border.”
    Nevada v. Hicks, 
    533 U.S. 353
    , 361 (2001); see also Surplus
    Trading Co. v. Cook, 
    281 U.S. 647
    , 651 (1930) (citing Indian
    reservations as examples of federally managed land within
    state territory).
    Even under the dissent’s reading of the statute, nothing
    would prevent the Nation from acquiring land in trust
    immediately adjacent to a city’s outermost boundary or even
    land that was almost, but not entirely encircled by corporate
    land.     This circumstance is not one in which “an
    administrative interpretation of a statute invokes the outer
    limits of Congress’ power.” Solid Waste Agency of N. Cook
    14
    To the extent the Arizona appellants argue that the Gila Bend Act
    impermissibly interferes with the state’s interest in maintaining its taxable
    land base, the text of the Act provides a definitive answer: “W ith respect
    to any private land acquired by the Tribe under section 6 and held in trust
    by the Secretary, the Secretary shall make payments to the State of
    Arizona and its political subdivisions in lieu of real property taxes.”
    § 7(a).

    County v. U.S. Army Corps of Engineers, 
    531 U.S. 159
    , 172
    (2001). Neither plausible construction of the statute “raise[s]
    serious constitutional problems” that counsel invocation of
    the clear statement rule. 
    Id.
     The dissent’s real concern about
    a casino abutting the City of Glendale is revealed in its effort
    to transform statutory interpretation of a federal trust land
    provision into a blocking effort by the city. At this stage, no
    one knows whether a casino will be approved. The Nation
    faces regulatory and court battles that are beyond the scope of
    this appeal. To convert this issue from one of Chevron
    deference to a sovereignty battle over regulation of Indian
    gaming distorts the clear statement rule.
    Although we disagree with the dissent’s position that the
    clear statement rule is dispositive here, the agency is free on
    remand to consider the rule, along with the Indian canon and
    other canons of statutory construction, to assist it in
    dispatching its duty to bring its policy and practical expertise
    to bear in interpreting § 6(d). Because we do not consider a
    jurisdictional interpretation of the provision to be foreclosed,
    “the agency has the option of adhering to its decision” on
    remand. Negusie, 
    555 U.S. at 525
     (Scalia, J., concurring).
    III.   THE INDIAN COMMERCE CLAUSE AND THE TENTH
    AMENDMENT
    The final issue is the claim that the Gila Bend Act
    exceeds Congress’s power under the Indian Commerce
    Clause and violates the Tenth Amendment. In rejecting this
    argument, the district court noted that “counsel for Glendale
    agreed during oral argument [that] Plaintiffs ask the Court to
    break new ground on this issue—to depart from every court
    decision that has previously addressed it.” See, e.g., Carcieri
    v. Kempthorne, 
    497 F.3d 15
    , 39–40 (1st Cir. 2007) (en banc),
    GILA RIVER INDIAN CMTY . V . UNITED STATES          33
    rev’d on other grounds, 
    555 U.S. 379
     (2009) (emphasizing
    that powers expressly delegated to Congress do not implicate
    the Tenth Amendment, and that “[b]ecause Congress has
    plenary authority to regulate Indian affairs, [the challenged
    act] does not offend the Tenth Amendment.”). On appeal, the
    Arizona appellants offer no such acknowledgment. The gist
    of their argument is that the Gila Bend Act infringes on
    Arizona’s sovereignty. Their effort to invoke Seminole Tribe
    of Florida v. Florida, 
    517 U.S. 44
     (1996), which considered
    the Eleventh Amendment’s express grant of state sovereign
    immunity, is unpersuasive and fails in the face of the broad
    powers delegated to Congress under the Indian Commerce
    Clause. U.S. Const. art. I, § 8, cl. 3.
    The Tenth Amendment provides that “powers not
    delegated to the United States by the Constitution, nor
    prohibited by it to the States, are reserved to the States
    respectively, or to the people.” U.S. Const. amend. X. The
    Supreme Court has read this Amendment as a “tautology”:
    “If a power is delegated to Congress in the Constitution, the
    Tenth Amendment expressly disclaims any reservation of that
    power to the States.” New York v. United States, 
    505 U.S. 144
    , 156–57 (1992). The question here is straightforward:
    Did Congress act within its powers under the Indian
    Commerce Clause in passing the Gila Bend Act? If so, the
    Tenth Amendment is not implicated, and the constitutional
    challenge fails.
    The Indian Commerce Clause empowers Congress “[t]o
    regulate Commerce . . . with the Indian Tribes.” U.S. Const.
    art. I, § 8, cl. 3. The Supreme Court has interpreted this
    clause broadly: “the central function of the Indian Commerce
    Clause is to provide Congress with plenary power to legislate
    in the field of Indian affairs.” Cotton Petroleum Corp. v. New
    34      GILA RIVER INDIAN CMTY . V . UNITED STATES
    Mexico, 
    490 U.S. 163
    , 192 (1989). That “Indian relations
    [are] the exclusive province of federal law” is beyond dispute.
    Cnty. of Oneida v. Oneida Indian Nation of New York State,
    
    470 U.S. 226
    , 234 (1985). See also Morton v. Mancari,
    
    417 U.S. 535
    , 552 (1974) (holding that the Indian Commerce
    Clause empowers Congress to “single[] Indians out as a
    proper subject for separate legislation.”).
    In passing the Gila Bend Act, Congress acted within its
    authority and expressly stated that it was fulfilling “its
    responsibility to exercise plenary power over Indian affairs to
    find alternative land for the [Nation].” H.R. Rep. 99-851 at
    7. As we learned from Garcia v. San Antonio Metro. Transit
    Auth., courts “have no license to employ freestanding
    conceptions of state sovereignty when measuring
    congressional authority under” a constitutionally enumerated
    power. 
    469 U.S. 528
    , 550 (1985). Passage of the Gila Bend
    Act was well within congressional power under the Indian
    Commerce Clause and is not trumped by the Tenth
    Amendment.
    AFFIRMED in part, REVERSED AND REMANDED
    in part as to the interpretation of § 6(d).
    Each party shall bear its own expenses on appeal.
    N.R. SMITH, Circuit Judge, dissenting:
    “Of all the attributes of sovereignty, none is more
    indisputable than that of [a State’s] action upon its own
    territory.” Green v. Biddle, 
    21 U.S. 1
    , 43 (1823). Yet today,
    the majority holds that it was permissible for an agency to
    GILA RIVER INDIAN CMTY . V . UNITED STATES                 35
    exercise what Chief Justice Roberts has called “an
    extraordinary assertion of power”1 by taking land into trust
    for an Indian reservation in the middle of one of Arizona’s
    most populated cities, contrary to the plain language of the
    Gila Bend Indian Reservation Lands Replacement Act, Pub.
    L. No. 99-503, 
    100 Stat. 1798
     (1986) (“Gila Bend Act”). The
    statutory text of the Gila Bend Act clearly prohibits the
    Secretary’s ability to take land, that is “within the corporate
    limits” of a city, into trust when the city’s limits wholly
    surround that land, such as the parcel at issue in this case.
    Furthermore, even if the Gila Bend Act is “ambiguous,”
    as the majority argues, the Supreme Court has made clear that
    courts should “not extend Chevron deference” to an agency
    decision where the “administrative interpretation alters the
    federal-state framework by permitting federal encroachment
    upon a traditional state power” such as the regulation of a
    State’s land not authorized by “a clear statement from
    Congress.” Solid Waste Agency of N. Cook Cnty. (SWANCC)
    v. U.S. Army Corps of Engineers, 
    531 U.S. 159
    , 172–74
    (2001); see also Gregory v. Ashcroft, 
    501 U.S. 452
    , 460–64
    (1991). Rather, courts should assume that, “the background
    principles of our federal system . . . belie the notion that
    Congress would use . . . an obscure grant of authority to
    regulate areas traditionally supervised by the States’ police
    power.” Gonzalez v. Oregon, 
    546 U.S. 243
    , 274 (2006).
    These concerns are particularly relevant here, where the
    Department of Interior made its decision in an ex-parte
    proceeding that did not involve the participation of the State
    of Arizona and without formal proceedings or a hearing for
    any other protesting parties.

    Carcieri v. Kempthorne, No. 07-526, Oral Arg. Tr. 36:13-17 (Nov. 3,
    2008).
    36     GILA RIVER INDIAN CMTY . V . UNITED STATES
    The majority’s decision to remand to the agency is
    improper, because “Congress has directly spoken to the
    precise question” before us. See Chevron, U.S.A., Inc. v.
    Natural Res. Def. Council, Inc., 
    467 U.S. 837
    , 842 (1984).
    We should resolve this case against the agency under
    Chevron step one, because the Secretary’s interpretation (1)
    is contrary to the plain language of the statute and (2)
    effectively renders political protections afforded to States in
    our federalism system virtually nonexistent. Thus, I must
    respectfully dissent.
    I.
    I generally agree with the facts and procedural history as
    set forth by the majority. Nevertheless, additional facts are
    relevant to my analysis in Part II. Thus, as the late Paul
    Harvey would say, “here’s the rest of the story.”
    A.
    The Tohono O’odham Nation (“the Nation”) is a federally
    recognized Indian tribe with the second largest Tribal land
    base in the United States at 2.8 million acres. That land base
    amounts to 4,375 square miles of reservation in South and
    Central Arizona. To put this size in perspective, the State of
    Connecticut is only slightly larger, at 5,006 square miles in
    area. The State of Delaware is less than half the size, at 2,026
    square miles.
    The Gila Bend Reservation had previously been part of
    the Nation’s land base. The reservation was nearly 10,000
    acres—less than .4 percent of the Nation’s total land
    holdings. When part of the Nation’s land was flooded as a
    result of problems with a federal dam project, Congress
    GILA RIVER INDIAN CMTY . V . UNITED STATES            37
    enacted the Gila Bend Act in 1986 to “replace[] . . . [Gila
    Bend Indian Reservation] lands with lands suitable for
    sustained economic use which is not principally farming
    . . . .” Pub. L. No. 99-503, § 2(4) 
    100 Stat. 1798
    . Under this
    Act, the Nation assigned to the United States all rights and
    title to 9,880 acres of the Gila Bend Reservation for $30
    million. 
    Id.
     at § 4(a). The Nation was then authorized to
    purchase replacement land, and the Secretary was authorized
    to take 9,880 acres of replacement land into trust, which
    would create a new Indian reservation. Id. at §6.
    In 2002, the Nation, along with many other tribes,
    publicly supported Proposition 202—a ballot measure
    designed to prevent construction of new casinos in Arizona
    cities. The Nation publicly asserted that it would not
    authorize additional Indian casinos in any cities.
    Then in 2003, the Nation bought Parcel 2 within the City
    of Glendale through a series of complex transactions using a
    shell company with an out-of-state address. Parcel 2 is land
    that is physically within Glendale’s corporate limits, but as a
    “county island,” it is unincorporated land under the
    jurisdiction of Maricopa County. County islands stem from
    a once-common practice called “strip annexation.” This type
    of annexation occurs when a city “extend[s its] boundaries by
    annexing long strips of property” that encircle other,
    unincorporated areas. Republic Inv. Fund I v. Town of
    Surprise, 
    800 P.2d 1251
    , 1254-55 (Ariz. 1990) (en banc).
    The practical benefits a city enjoys once unincorporated
    land is surrounded by the city’s jurisdictional boundaries are
    two-fold. First, cities are able to “exercise a strong degree of
    control over zoning and development” of county islands,
    because a city’s land-use planning documents and zoning
    38     GILA RIVER INDIAN CMTY . V . UNITED STATES
    ordinances are able to guide the zoning and subdivision of
    county islands. Carefree Improvement Ass’n v. City of
    Scottsdale, 
    649 P.2d 985
    , 986–87, 992 (Ariz. Ct. App. 1982);
    
    Ariz. Rev. Stat. § 11-814
    (G) (“The rezoning or subdivision
    plat of any unincorporated area completely surrounded by a
    city or town shall use as a guideline the adopted general plan
    and standards as prescribed in the subdivision and zoning
    ordinances of the city or town after April 10, 1986.”
    (emphasis added)). Second, generally no other municipality
    can annex unincorporated land such as Parcel 2 that is within
    a city’s geographic limits. See Carefree Improvement Ass’n,
    
    649 P.2d at 986
    ; 
    Ariz. Rev. Stat. § 9-101.01
    .
    The City of Glendale’s exterior corporate boundary was
    extended to encircle Parcel 2 in 1977. Since that time,
    Glendale has controlled and guided the zoning and
    subdivision development of Parcel 2 and the surrounding
    land. Indeed, Parcel 2 is part of Glendale’s Municipal
    Planning Area and is included in Glendale’s General Plan.
    Currently, Parcel 2 has a rural zoning designation (R-43) that
    would allow only limited development.
    The City of Glendale developed the surrounding area in
    reliance on its ability to control the zoning designation and
    land-use of Parcel 2 under this legal scheme. For instance, in
    2005 Glendale finished building a new public high school
    directly across the street from what Glendale later learned
    was the Nation’s acreage. Glendale, as well as private
    parties, has also invested significant resources in the area by
    building a $450 million stadium, a $240 million arena, and a
    $120 million Major League Baseball training facility.
    In January 2009, the Nation transferred ownership of
    Parcel 2 to itself. Only days later, it filed its application
    GILA RIVER INDIAN CMTY . V . UNITED STATES            39
    asking the Secretary to take the property into trust and grant
    the Nation permission to establish a Class III, Las Vegas-style
    gambling facility. 
    25 U.S.C. § 2703
    . The Nation has
    advertised that this “new casino will be the largest in the
    state.” There are currently no gaming facilities within the
    City of Glendale. More than 30,000 people live within two
    miles of the proposed casino in what is currently described as
    a “family friendly” area.
    B.
    Pursuant to usual practices, the Department of Interior
    treated the Nation’s land-into-trust application as an ex parte
    filing. It never notified the public of the application, created
    a docket, set a pleading schedule, or held a hearing, because
    it was not required to do so under the notice and comment
    provisions of 
    25 C.F.R. §§ 151.10
     and 151.11(d). Opponents
    of the application (who happened to be aware of the
    proceedings) were able to submit arguments against the
    application by letter only. Though the majority makes much
    of these “lengthy submissions,” Maj. Op. 13–14, the length
    of the letters submitted by these parties hardly improved the
    process by which these parties could contest the Secretary’s
    actions. The opposing parties were never alerted when the
    Secretary filed amendments to its application. Further, the
    State of Arizona did not even participate in this limited
    fashion.
    In 2010, the Secretary concluded that Parcel 2 was
    eligible to be taken into trust under the Gila Bend Act. The
    Secretary determined that “the meaning of ‘corporate limits’
    is plain” and “shows a clear intent to make property eligible
    under the Act if it is on the unincorporated side of a city’s
    boundary line.” The Department of Interior then published a
    40      GILA RIVER INDIAN CMTY . V . UNITED STATES
    Federal Register notice announcing its final determination “to
    acquire Parcel 2 consisting of 53.54 acres of land into trust
    for the Tohono O’odham Nation . . . .” 75 Fed.Reg.
    52550–01, 52550 (Aug. 26, 2010). The Secretary has stayed
    the acquisition for litigation proceedings.
    Plaintiffs sought review in district court. There, they
    raised both statutory and constitutional arguments that had
    been raised before the agency. The district concluded that the
    “within the corporate limits” phrase was “ambiguous” and
    applied Chevron deference to uphold the agency’s decision.
    See Chevron, 
    467 U.S. at
    842–43.2 Plaintiffs sought an
    injunction to block the Secretary from taking Parcel 2 into
    trust during the appeal; the district court granted the
    injunction, concluding that Plaintiffs raised “difficult” and
    “substantial legal questions warranting more deliberative
    consideration on appeal.” The district court also concluded
    there would be irreparable harm, because Glendale would
    lose its right to annex the land if it were taken into trust,
    which would lead to “irreparable quality-of-life injuries from
    gaming activities on Parcel 2.”3
    2
    The majority says that the district court “conclud[ed] that the Secretary
    of the Interior correctly applied the” Gila Bend Act. Majority Op. 10.
    This is a slight misstatement. The district court found “the meaning of
    ‘within the corporate limits’ to be ambiguous” in the Gila Bend Act. Gila
    River Indian Cmty. v. United States, 
    776 F. Supp. 2d 977
    , 987 (D. Ariz.
    2011). After conducting its own analysis and finding both parties’
    interpretation plausible, the district court contemplated what it must do
    when “both sides advocate reasonable interpretations” and concluded that
    it “must defer to the agency’s interpretation.” 
    Id. at 989
    . Thus, the court
    deferred to the agency’s interpretation because it was reasonable, but it did
    not necessarily find that it was the correct interpretation.
    3
    The district court also enjoined Glendale from annexing Parcel 2 to
    preserve the status quo.
    GILA RIVER INDIAN CMTY . V . UNITED STATES            41
    II.
    The majority concludes that the phrase “within the
    corporate limits” in the Gila Bend Act is “ambiguous,” and
    thus remands to the agency to allow the Secretary “to bring
    his expertise to bear to interpret the provision anew.” Maj.
    Op. 21. I disagree that the phrase is ambiguous for two
    reasons.
    A.
    First, as the Supreme Court has held, “the susceptibility
    of [a] word . . . to alternative meanings does not render the
    word whenever it is used, ambiguous, particularly where all
    but one of the meanings is ordinarily eliminated by context.”
    Carcieri v. Salazar, 
    555 U.S. 379
    , 390 (2009) (alterations and
    internal quotation marks omitted). In Carcieri, the Supreme
    Court ruled in favor of the State and prevented an Indian tribe
    from taking land into trust in the middle of a city by
    concluding that the statute was “clear.” 
    Id.
     The Court
    arrived at this conclusion despite the conclusion of the court
    of appeals below that the statute was ambiguous.
    Here, as in Carcieri, the statutory context makes clear that
    “within the corporate limits” refers to land that is
    geographically enclosed in the jurisdictional limits of a city.
    Under the Gila Bend Act, the Secretary can only take land
    into trust upon the completion of certain statutory conditions,
    the most important of which are in Section 6(d) and relate to
    the size and location of land parcels:
    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
    42     GILA RIVER INDIAN CMTY . V . UNITED STATES
    subsection (c) which meets the requirements
    of this subsection. . . . 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 sentence if he
    determines that additional areas are
    appropriate.
    Pub. L. No. 99-503, § 6(d) 
    100 Stat. 1798
     (emphasis added).
    Thus, the plain language of the Gila Bend Act makes
    clear that it was aimed at allowing the Nation to assemble
    new reservation land consisting of a few large tracts of land,
    none of which were within a city. While the Secretary could
    waive the contiguity and three-tract requirements where
    “appropriate,” the committee report indicates that Congress
    anticipated “appropriate” circumstances to include only those
    situations where parcels were “not entirely contiguous,” but
    were “sufficiently close to be reasonably managed as a single
    economic unit or residential unit.” H.R. Rep. No. 99-851, at
    11 (1986). Parcel 2 is more than 100 miles from the Nation’s
    existing reservation. Nothing in the text of Section 6(d)
    anticipates that Arizona expected trust land to be purchased
    in little patches sprinkled throughout the State, and
    particularly not inside the exterior boundary of cities. Rather,
    the Gila Bend Act makes land ineligible to be taken into trust
    GILA RIVER INDIAN CMTY . V . UNITED STATES                       43
    if it lies physically inside, or within, the boundary, or limits
    of a city.
    When there is “no evidence that the words . . . have
    acquired any special meaning in trade or commerce, they
    must receive their ordinary meaning” based on “the common
    language of the people . . . .” Nix v. Hedden, 
    149 U.S. 304
    ,
    306–07 (1893). The ordinary meaning of “within” is defined
    as “[i]n or into the inner part; inside.” The American
    Heritage Dictionary 1471 (1976). “Limit” means “the final
    or furthest confines, bounds, or restriction of something.” Id.
    at 758. Thus, Parcel 2 is within Glendale’s corporate limits,
    because it is “inside” the “final or furthest confines” or
    “bounds” of the City.4 This is the obvious, plain meaning of
    the text that Congress likely understood when enacting
    Section 6(d) of the Gila Bend Act.
    In contrast to this natural reading of the statute, the United
    States and the Nation argue that there are “two relevant
    boundaries: the city’s exterior boundary and the interior
    boundary,” and “only land that is between those two
    boundaries” is within corporate limits. Such an interpretation
    strains common sense, and is certainly not the obvious
    reading of the statute based on the “common language of the
    people.” Nix, 
    149 U.S. at 307
    . If Congress had wanted to
    4
    In its cross motion for summary judgment, the United States also
    agreed to the Black’s Law D ictionary definition “within” and “limit.”
    “W ithin” is defined as “[i]n inner or interior part of.” Black’s Law
    Dictionary 1602 (6th ed. 1990). “Limit” is defined as “[b]oundary,
    border, or outer line of a thing.” Id. at 926. These definitions also support
    a plain meaning interpretation of the Gila Bend Act supporting the City’s
    interpretation, because Parcel 2 is in the “inner or interior part of” the
    City’s “[b]oundary, border, or outer line.”
    44     GILA RIVER INDIAN CMTY . V . UNITED STATES
    refer to two boundaries, or to incorporated land only, it could
    have easily made that distinction.
    Indeed, other statutes by Congress in similar
    circumstances indicate that, if Congress only wished to refer
    to a municipality’s incorporated or annexed land, it knew how
    to do so. See, e.g., 
    25 U.S.C. § 1724
    (i)(2) (allowing Indian
    tribe to use government-provided funds to purchase “acreage
    within . . . unincorporated areas of the State of Maine”
    (emphasis added)); see also Pub. L. No. 102–402, § 4(d)(1),
    
    106 Stat. 1961
    , 1965 (1992) (referring to “annexation of
    lands within the refuge by any unit of general local
    government” (emphasis added)); Pub. L. No. 101–514, 
    104 Stat. 2074
    , 2076 (1991) (referring to “all incorporated units
    within the town of Matewan” (emphasis added)); Pub. L. No.
    100–693, § 3(a), 
    102 Stat. 4559
     (1988) (referring to “the
    incorporated area of the cities of Union City and Fremont”
    (emphasis added)). This contradicts the argument of the
    United States and the Nation that “within the corporate
    limits” means both within the exterior and the interior
    corporate limits of a city.
    Furthermore, even if the “within the corporate limits”
    phrase does have a specific “settled meaning,” (as the United
    States and the Nation contend), the background legal norms,
    against which Congress is presumed to be aware when it
    legislates, most clearly supports the City of Glendale’s
    interpretation of the statute. The most relevant background
    legal norm to the Gila Bend Act is Arizona state law, because
    the Gila Bend Act only affects Arizona, and it is “a fair and
    reasonable presumption . . . that [C]ongress” is aware of
    “state legislation” when the act of Congress has an effect on
    that law. See Prigg v. Commw. of Pa., 
    41 U.S. 539
    , 598–99
    (1842); see also Brock v. Writers Guild of Am., W., Inc.,
    GILA RIVER INDIAN CMTY . V . UNITED STATES           45
    
    762 F.2d 1349
    , 1358 n.8 (9th Cir. 1985) (“[B]ecause
    Congress is composed predominately of lawyers, court[s]
    may assume that Congress is aware of existing law.”).
    Notably, Arizona’s zoning ordinances use the “within
    corporate limits” phrase in the geographical sense. For
    instance, Arizona Revised Statutes Section 9-461.11(A)
    allows a municipality to exercise its “planning powers” over
    “unincorporated territory” that is “within its corporate limits
    . . . .” (emphasis added). See also 
    id.
     § 9-462.07(A) (same).
    The Arizona Supreme Court has also interpreted the
    words “corporate limits” to refer to a municipality’s “exterior
    boundar[ies],” holding that a state university campus was
    located “within” the City of Flagstaff’s corporate limits,
    because it was “completely surround[ed]” by the “exterior
    boundary of Flagstaff.” Flagstaff Vending Co. v. City of
    Flagstaff, 
    578 P.2d 985
    , 987 (Ariz. 1978) (in banc). The
    court emphasized that “the ordinary meaning of ‘within’” is
    “on the innerside . . . inside the bounds of a region.” 
    Id.
    (internal quotation marks omitted) (quoting Webster’s Third
    New International Dictionary 2627 (1965)). Notably, the
    Arizona Supreme Court’s interpretation turned on the
    geographic location of the campus, not its jurisdictional
    status.
    While not binding on this court, Flagstaff Vending is
    persuasive authority that Congress understood “within the
    corporate limits” to refer to the geographic boundaries of a
    city when the Gila Bend Act was passed. This is particularly
    likely, because Flagstaff Vending was decided only eight
    years before two of Arizona’s representatives
    (Representative Morris K. Udall and then Representative
    John McCain) sponsored the Gila Bend Act.
    46      GILA RIVER INDIAN CMTY . V . UNITED STATES
    Though the majority relies on situations where Congress
    has used the phrase “exterior boundaries,” these statutes are
    completely inapposite. Maj. Op. 23 (citing 
    16 U.S.C. § 485
    ;
    
    25 U.S.C. § 465
    ). These statutes are in no way referring to
    unincorporated islands of land surrounded by an outer
    corporate limit, and thus there is nothing to indicate these
    statutes would have any bearing on this factually distinct
    situation. Rather, they merely refer to the “exterior
    boundary” of an area, such as a national forest. Furthermore,
    as discussed above, the Arizona Supreme Court had already
    interpreted “corporate limit[]” to be synonymous with
    “exterior boundary.” Flagstaff Vending Co., 
    578 P.2d at 987
    .
    It is likely that Congress also viewed these phrases as
    synonymous, so there is nothing significant about Congress
    using the “exterior boundaries” phrase in these statutes.
    The Nation is correct that Arizona’s 1977 annexation
    ordinance “extended” the City of Glendale’s “present
    corporate limits . . . to include” a strip of land surrounding
    Parcel 2. But that merely meant that the annexed strip then
    formed part of the “corporate limits.” The encircled land
    (Parcel 2) still fell within those limits. Nothing about this
    ordinance defined the term “within” in a way that would
    detract from this plain meaning.5
    5
    The majority cites to Arizona Revised Statutes Section 9-500.23, a
    non-zoning ordinance about fire and safety, which “outside corporate
    limits” in a jurisdictional sense. However, the jurisdictional usage makes
    sense in this context, because which entity is authorized to provide fire
    and safety services is an issue of authority and jurisdiction. In fact, this
    ordinance is entitled “Authority to provide fire protection and emergency
    services outside corporate limits.” Thus, the jurisdictional nature of the
    “corporate limits” phrase used there is distinguishable from the geographic
    nature of the phrase used in a zoning context, and the majority’s reliance
    on this ordinance is misplaced.
    GILA RIVER INDIAN CMTY . V . UNITED STATES                      47
    Notably, in a 1992 Legal Brief, the Department of the
    Interior itself recognized that Section 6(d) created
    “geographical requirements” to take the land into trust only
    if it was “outside the corporate limits of any city or town.”
    Brief for Appellee at 4, Tohono O’odham Nation v. Bureau
    of Indian Affairs, 22 IBIA 220 (I.B.I.A. Aug. 14, 1992). This
    position is directly contrary to the Department’s July 2010
    position in this case that the “within the corporate limits”
    phrase is “jurisdictional in nature.”
    “If the plain language of [the Act] renders its meaning
    reasonably clear,” the court “will not investigate further
    unless its application leads to unreasonable or impracticable
    results.” United States v. Fei Ye, 
    436 F.3d 1117
    , 1120 (9th
    Cir. 2006) (internal quotation marks omitted). Therefore,
    because the meaning of the Act is clear at step one of the
    Chevron analysis, no deference is owed to the Secretary’s
    interpretation. See Gen. Dynamics Land Sys., Inc. v. Cline,
    
    540 U.S. 581
    , 600 (2004) (“Even for an agency able to claim
    all the authority possible under Chevron, deference to its
    statutory interpretation is called for only when the devices of
    judicial construction have been tried and found to yield no
    clear sense of congressional intent.”).
    Other state cases interpreting identical “within the corporate limits”
    language have come to the same conclusion as the Supreme Court of
    Arizona. See, e.g., Village of Frankfort v. Ill. EPA, 
    852 N.E.2d 522
    , 524
    (Ill. App. Ct. 2006) (referring to unincorporated land “within the corporate
    limits of Frankfort”); City of Des Moines v. City Dev. Bd., 335 N.W .2d
    449, 450 (Iowa Ct. App. 1983) (city “notified respondent . . . that the city
    would not provide essential services to isolated unincorporated areas
    within the corporate limits of the city”); Town of Germantown v. Village
    of Germantown, 235 N.W .2d 486, 491 (Wis. 1975) (interpreting statute as
    giving municipalities an opportunity to annex islands “lying within the
    corporate boundaries”).

    B.
    Even if the majority is correct that the statute is
    ambiguous, there is a second reason that the majority’s
    decision to remand is incorrect. The Supreme Court’s
    federalism canon of construction,6 which operates at step one
    6
    The United States argues that the Indian canon of construction,
    requiring a liberal interpretation of statutes in favor of Indians, requires a
    ruling for the Nation if the Gila Bend Act is ambiguous. See Montana v.
    Blackfeet Tribe of Indians, 
    471 U.S. 759
    , 766 (1985). However, the
    district court found that the Secretary’s interpretation would adversely
    affect the economic interests of other Indian tribes in Arizona. This canon
    does not appear to apply when it will benefit one tribe at the expense of
    other Indian tribes. See Confederated Tribes of Chehalis Indian
    Reservation v. Washington, 
    96 F.3d 334
    , 340 (9th Cir. 1996) (declining to
    apply canon where multiple tribes dispute fishing rights); see also
    Northern Cheyenne Tribe v. Hollowbreast, 
    425 U.S. 649
    , 655 n.7 (1976)
    (declining to apply canon because the “contesting parties are an Indian
    tribe and a class of individuals consisting primarily of tribal members”).
    Furthermore, Supreme Court precedent suggests that when the Indian
    canon conflicts with the federalism canon, the federalism canon prevails.

    Interpretation 374–75 (2d ed. 2006) (“[T]he canon promoting

    discussion of the background justifications for this clear
    statement rule illustrates the relevance of this canon here.
    The debate over what constitutes the appropriate balance
    of power between the states and federal government
    and—more relevant to this case—how that balance of power
    should be enforced, dates back to the founding of this nation.
    Regarding the specific interpretation that should be given to
    the Tenth Amendment, one position in this debate has been
    that it is the role of the judiciary to protect state interests by
    interpreting the Tenth Amendment as a substantive limit on
    federal power. The competing argument is that States are
    able to adequately protect their interests through the political
    process, so no additional judicial protections should be
    provided. Over the course of American history, federal
    courts have not always taken consistent positions on this
    issue.9
    For instance, prior to Garcia v. San Antonio Metropolitan
    Transit Authority, 
    469 U.S. 528
     (1985), the Supreme Court
    had, from time to time, employed the Tenth Amendment as
    a substantive limit on the federal government’s ability to
    9
    Compare Hammer v. Dagenhart, 
    247 U.S. 251
     (1918) (holding that a
    federal law prohibiting interstate shipment of goods that utilized child
    labor violated the Constitution, because “[t]he power of the States to
    regulate their purely internal affairs by such laws as seem wise to the local
    authority is inherent and has never been surrendered to the general
    government”); Bailey v. Drexel Furniture Co., 
    259 U.S. 20
    , 38 (1922)
    (same), with United States v. Darby, 
    312 U.S. 100
    , 124 (1941) (holding
    that a federal law prohibiting shipment of goods made by children was
    Constitutional, because the Tenth Amendment was merely a reminder that
    “all is retained which has not been surrendered”).
    GILA RIVER INDIAN CMTY . V . UNITED STATES                   51
    exercise power.10 The case of National League of Cities v.
    Usery, 
    426 U.S. 833
     (1976) was a Supreme Court case that
    used the Tenth Amendment in this manner.
    In Garcia, the Court expressly overruled National League
    of Cities, because using the Tenth Amendment as a
    substantive limit on Congress proved “unworkable in
    practice,” even if it had some basis in Constitutional theory.
    
    469 U.S. at
    545–47. The Court in Garcia did argue for
    judicial restraint when it came to rules that “look[ed] to the
    ‘traditional,’ ‘integral,’ or ‘necessary’ nature of governmental
    functions . . . .” 
    Id. at 546
    . The Court also emphasized that
    States continue to “occupy a special and specific position in
    our constitutional system and that the scope of Congress’
    authority under the Commerce Clause must reflect that
    position.” 
    Id. at 556
    .
    However, the Court explained that the protection of State
    interests occurred through the political process and not the
    judiciary. “[T]he principal and basic limit on the federal
    commerce power is that inherent in all congressional
    action—the built-in restraints that our system provides
    through state participation in federal governmental action.
    The political process ensures that laws that unduly burden the
    states will not be promulgated.” 
    Id.
     (emphasis added) The
    Court observed that “[i]n the factual setting of these cases the
    internal safeguards of the political process have performed as
    intended.”

    See, e.g., Carter v. Carter Coal Co.,

    grounds); United States v. Butler, 
    297 U.S. 1
     (1936) (striking down part
    of the Agricultural Adjustment Act that imposed taxes on agricultural
    processors under the Tenth Amendment).
    52     GILA RIVER INDIAN CMTY . V . UNITED STATES
    Only six years after Garcia, the Supreme Court
    apparently sought to strike a compromise between these
    competing positions when it decided Gregory v. Ashcroft,
    
    501 U.S. 452
    . There, the Court used the Tenth Amendment
    and federalism considerations as a rule of construction
    preventing federal laws from being interpreted in a way that
    burdened substantial state interests unless Congress clearly
    authorized such an interpretation of the law. The Court
    explained, “inasmuch as this Court in Garcia has left
    primarily to the political process the protection of the States
    against intrusive exercises of Congress’ Commerce Clause
    powers, we must be absolutely certain that Congress intended
    such an exercise.” 501 U.S. at 464; see also 1 Laurence
    Tribe, American Constitutional Law 1176 (3d ed. 2000)
    (“[T]o give the state-displacing weight of federal law to mere
    constitutional ambiguity would evade the very procedure for
    lawmaking on which Garcia relied to protect states’
    interests.”).
    In other words, to the extent that Garcia anticipated that
    States would be protected by “the internal safeguards of the
    political process” when the political process “performed as
    intended,” Gregory created a rule of construction aimed at
    ensuring that these political safeguards actually had
    “performed as intended” before significant state interests
    would be burdened. Garcia, 
    469 U.S. at 556
    . Thus, the
    Gregory Court explained that Congress’s authority under the
    Supremacy Clause to preempt state law “in areas traditionally
    regulated by the States” is “an extraordinary power in a
    federalist system” that “we must assume Congress does not
    exercise lightly.” 501 U.S. at 460.
    A canon of construction favoring a State’s sovereign
    interests is not new. The Supreme Court has long explained
    GILA RIVER INDIAN CMTY . V . UNITED STATES                  53
    that when federal law is arguably inconsistent with state law,
    courts must “start with the assumption that the historic police
    powers of the States were not to be superseded by the Federal
    Act unless that was the clear and manifest purpose of
    Congress.” Rice v. Santa Fe Elevator Corp., 
    331 U.S. 218
    ,
    230 (1947).11 However, the Supreme Court’s decision in
    Gregory appears to have transformed this presumption into a
    much more exacting clear statement rule requiring additional
    clarity from Congress.12
    As the dissent in Gregory noted, to overcome a federalism
    presumption, Congress would be required both to make clear
    1) that the statute was intended to extend “to the States” at all,
    and 2) Congress must also be clear as to whether “the precise
    details of the statute’s application” were meant to apply to the
    specific state activities at issue. 501 U.S. at 476 (White, J.,
    dissenting).13

    Thus, even if the Gila Bend Act is, as the majority
    concludes, “ambiguous” and “less than crystal clear,” this
    only means that Congress never actually considered the issue
    of creating an Indian reservation on an unincorporated island
    within the geographic limits of a city. While statutory
    ambiguity in other contexts generally requires courts to defer
    to an agency’s interpretation, Chevron, 
    467 U.S. 837
    , the
    federalism clear statement rule prevents Congress from
    punting this highly charged political decision to the less
    That this two-tier analysis exists is demonstrated by the fact that the
    Supreme Court has upheld the imposition of the exact same federal statute
    against states in some instances where the statute’s application was clear,
    but not in other instances where the statute’s application was less than
    clear. For example, in SWANCC, 
    531 U.S. at 162
    , the statutory
    interpretation question was whether an abandoned sand and gravel pit
    constituted “navigable waters,” as interpreted by the United States Army
    Corps of Engineers. The Supreme Court struck down the application of
    the “navigable waters” provision in the Clean W ater Act to a land-locked
    gravel pit in one instance. 
    531 U.S. at 162
     (“W e are asked to decide
    whether the provisions of § 404(a) may be fairly extended to these waters
    . . . .” (emphasis added)). This was because, though it was clear that the
    Clean W ater Act could be applied by agencies against the states in
    general, the intrusive application in SWANCC was not clearly authorized
    by Congress in that case, where the application raised heightened
    federalism concerns. But the Court noted that, in United States v.
    Riverside Bayview Homes, Inc., 
    474 U.S. 121
    , 134 (1985), the Court
    upheld the application of the exact same statute to water that was adjacent
    to and “inseperably bound up with” navigable waters. 
    Id. at 167
    .
    Similarly, in Gregory, the Supreme Court struck down the application
    of the ADEA to potentially include retirement requirements on state
    judges. 
    501 U.S. 452
    . But in Kimel v. Florida Bd. of Regents, 
    528 U.S. 62
     (2000), the Supreme Court found the same statute, the ADEA, satisfied

    For instance, in SWANCC, the agency specifically
    requested that Chevron deference be provided, because
    Congress “did not address the precise question of [the
    statute’s] scope with regard to nonnavigable, isolated,
    intrastate waters, and that, therefore, [the Court] should give
    deference to the [agency’s] ‘Migratory Bird Rule.’” 
    531 U.S. at 172
    . The Seventh Circuit had deferred to the agency’s
    interpretation after determining that the interpretation was
    “reasonable.” 
    Id. at 166
    . However, the Court reversed the
    Seventh Circuit and explicitly stated that, “even were we to
    agree with respondents, we would not extend Chevron
    deference here.” 
    Id. at 172
    . The Court invoked the
    federalism cannon of statutory interpretation and explained
    that its concern with the agency’s interpretation was
    “heightened where the administrative interpretation alters the
    federal-state framework by permitting federal encroachment
    upon a traditional state power.” 
    Id.
     at 173 (citing Bass,
    
    404 U.S. at 349
     (“[U]nless Congress conveys its purpose
    clearly, it will not be deemed to have significantly changed
    the federal-state balance.”)). Thus, because the Court found
    “nothing approaching a clear statement from Congress that it
    intended” the statute to be applied as it was in the present
    case, the Court “read the statute as written to avoid the
    significant constitutional and federalism questions . . . and

    therefore reject[ed] the request for administrative deference.”
    
    Id.
     (emphasis added).
    Similarly, in Gregory, 
    501 U.S. 452
    , the majority rejected
    the EEOC’s interpretation of the statute without even
    mentioning deference to the agency. It was only in Justice
    Blackmun’s dissent where Chevron was discussed, and he
    argued that the Court should have deferred to the EEOC’s
    interpretation of a vague statute. 
    Id. at 493
     (Blackmun, J.,
    dissenting); see also Gonzalez v. Oregon, 
    546 U.S. at 264, 274
     (finding that the Attorney General’s interpretive rule was
    “not entitle[d] . . . to Chevron deference,” based on, inter
    alia, “background principles of our federal system”). In other
    words, in areas where federalism concerns are implicated, it
    appears that a clear authorization of Congressional authority
    is a preliminary requirement for any deference to be accorded
    to the agency’s interpretation of a statute.15
    Contrary to the majority’s concerns about hypothetical
    applications of this rule, the federalism canon of construction
    does not preclude deference to any agency interpretation of
    “any and all . . . federal legislation [that] could be construed
    to have at least minor, derivative implications for traditional
    state functions.” Maj. Op. 30. Rather, the Supreme Court has
    15
    Clear statement “canons reflect a singular requirement that certain
    important issues be addressed by legislative deliberation alone. More
    specifically, they operate as clear statement rules that bar the interpretation
    of a statute to push the bounds of federal power absent an unambiguous
    declaration of intent by Congress.” Bamberger, supra note 6, at 79 (citing
    Cass R. Sunstein, Beyond Marbury: The Executive’s Power To Say What
    the Law Is, 
    115 Yale L.J. 2580
    , 2607 (2006)). The canons also “force a
    democratically elected Congress to deliberate on, and then raise, a
    question via explicit statement by operating in a manner that constrains
    any interpretive discretion on the part of courts and agencies.” Id. at 80.
    GILA RIVER INDIAN CMTY . V . UNITED STATES             57
    only applied this rule in narrow circumstances when the
    following three types of specific concerns arise. First, this
    rule has only been used by the Supreme Court in particular
    substantive legal “areas traditionally supervised by the States’
    police power.” Gonzalez v. Oregon, 
    546 U.S. at 274
    . The
    Supreme Court has demonstrated its commitment to
    protecting a State’s ability to regulate the land use and private
    property rights within its own territory. For instance, in
    SWANCC, the Supreme Court recognized that the agency’s
    interpretation would result in “a significant impingement of
    the States’ traditional and primary power over land and water
    use” as a justification for invoking the clear statement rule.
    
    531 U.S. at 174
    ; see also Hess v. Port Auth. Trans-Hudson
    Corp., 
    513 U.S. 30
    , 44 (1994) (“[R]egulation of land use [is]
    a function traditionally performed by local governments.”).
    Similarly, in BFP, 
    511 U.S. at
    544–45, the majority opinion
    invoked the Gregory clear statement rule in support of a
    reading that prevented federal law from trumping state law
    concerning the regulation of private property rights.
    Second, the clear statement rule only applies when “a
    statute [is] susceptible of two plausible interpretations, one of
    which would have altered the existing balance of federal and
    state powers.” Salinas v. United States, 
    522 U.S. 52
    , 59,
    
    118 S. Ct. 469
    , 474, 
    139 L. Ed. 2d 352
     (1997); see also
    United States v. Nordic Vill., Inc., 
    503 U.S. 30
    , 34 (1992)
    (applying a similar rule of construction where a was
    “susceptible of at least two interpretations,” one of which was
    more intrusive on a state’s interests). For instance, in Coeur
    Alaska, Inc. v. Southeast Alaska Conservation Council,
    
    557 U.S. 261
    , 265, 273 (2009), the clear statement rule did
    not apply, because the question was merely about which
    agency had authority to issue discharge permits, rather than
    whether an agency had authority to perform the action at all.
    58     GILA RIVER INDIAN CMTY . V . UNITED STATES
    Though the Court explained that the statute may be
    ambiguous, either interpretation had a similar effect on the
    State’s interests, and thus the Court deferred to the agency’s
    interpretation rather than applying the clear statement rule.
    
    Id.
     at 274–75.
    In contrast, in Gregory, one interpretation of the ADEA
    would have allowed an agency to regulate retirement
    requirements for state judges—a significant intrusion on state
    interests, whereas the other interpretation would not allow
    such regulation. 501 U.S. at 469. Similarly in SWANCC, the
    potential ambiguity in the Clean Water Act was over whether
    or not the Army Corps could regulate a land-locked,
    abandoned gravel pit “wholly located within two Illinois
    counties,” despite the fact that the agency did clearly have
    authority under the same statute to regulate other state land
    that “actually abutted on a navigable waterway.” 
    531 U.S. at 167, 171
    . The Court noted that, while the text of the Clean
    Water Act supported the latter interpretation, there was
    nothing to indicate that Congress had supported the former
    “more expansive” interpretation of “navigable waters.” 
    Id.
     at
    168–71. In other words, the type of ambiguity in the statute
    must be such that it is not clear that the State was able to
    protect its significant interests through the political process,
    because the State may not have been on notice that its
    important interests were at stake.
    Third (and this factor applies only in the administrative
    context), the Supreme Court seems more likely to apply this
    clear statement requirement when the agency interprets the
    scope of its own statutory authority to regulate in the
    traditional state realm at issue. For instance, in Gonzalez v.
    Oregon, the Supreme Court explained that it is a
    “commonsense conclusion” that “[j]ust as the conventions of
    GILA RIVER INDIAN CMTY . V . UNITED STATES                     59
    expression indicate that Congress is unlikely to alter a
    statute’s obvious scope and division of authority through
    muffled hints, the background principles of our federal
    system also belie the notion that Congress would use such an
    obscure grant of authority to regulate areas traditionally
    supervised by the States’ police power.” 
    546 U.S. at 274
    .
    The Court thus explained that “[t]he idea that Congress gave
    the Attorney General such broad and unusual authority
    through an implicit delegation . . . is not sustainable.” 
    Id. at 267
    . The Court quoted Whitman v. American Trucking
    Associations, Inc., 
    531 U.S. 457
    , 468 (2001), where it had
    previously explained that “Congress, we have held, does not
    alter the fundamental details of a regulatory scheme in vague
    terms or ancillary provisions—it does not, one might say,
    hide elephants in mouseholes.” Id.16
    This concern regarding the agency’s interpretation of its
    own statutory authority compounds when the agency’s
    interpretation of the authority-granting statute itself strains
    the bounds of Congress’s constitutional authority. For
    example, in SWANCC, the Court explained that “[w]here an
    16
    See also Wyeth v. Levine, 
    555 U.S. 555
    , 576–77 (2009) (the Court
    gave no weight to the agency’s conclusion that state law is pre-empted);
    FD A v. Brown & Williamson Tobacco Corp., 
    529 U.S. 120
    , 160 (2000)
    (“[W ]e are confident that Congress could not have intended to delegate a
    decision of such economic and political significance to an agency in so
    cryptic a fashion.”); Robin Kundis Craig, Administrative Law in the
    Roberts Court: The First Four Years, 
    62 Admin. L. Rev. 69
    , 171 (2010)
    (“The Roberts Court’s track record to date indicates that it will generally
    accord far less deference to a federal agency when the agency is
    determining the scope of its own jurisdictional authority. This inclination
    is particularly strong when the agency is expanding its authority into
    realms that the Court perceives as the states’— for example, regulation of
    doctors, retention of legal authority over land, and land-use planning.”
    (emphasis added)).
    60     GILA RIVER INDIAN CMTY . V . UNITED STATES
    administrative interpretation of a statute invokes the outer
    limits of Congress’ power, we expect a clear indication that
    Congress intended that result.” 531 U.S. at 172. The Court
    explained that this concern stems from the “assumption that
    Congress does not casually authorize administrative agencies
    to interpret a statute to push the limit of congressional
    authority.” Id. at 172–73. However, while constitutional
    limits may heighten concerns about authority, clear statement
    rules “cannot be defended as a simple invocation of the rule
    about avoiding serious constitutional questions,” because
    these rules apply even in situations where, “if Congress acted
    with the requisite clarity, the statute would be constitutional.”
    William N. Eskridge, Jr., et. al., Legislation and Statutory
    Interpretation 368 (2d ed. 2006).
    Under this third concern, the federalism clear statement
    rule is satisfied when a statutory grant of authority to an
    agency is without reservation and clearly encompasses the
    scope of the subject matter. See Yeskey, 
    524 U.S. at
    208–10.
    But when there is some reservation of authority and it is not
    clear if the agency’s interpretation is statutorily authorized,
    the clear statement rule applies in full force. SWANCC,
    531 U.S. at 172-74; Gregory, 
    501 U.S. 452
    ; see also
    Gonzalez v. Oregon, 
    546 U.S. at
    295–300.
    All three of the specific concerns related to the federalism
    canon are present in this case. First, the Secretary’s
    interpretation of the Gila Bend Act clearly implicates
    Arizona’s “traditional and primary power over land . . . use”
    and private property rights within its territory. See SWANCC,
    531 U.S. at 174. I am surprised by the majority’s argument
    that no “encroachment on state power” is at issue in this case.
    Maj. Op. 30 (emphasis added). Although the City of
    Glendale is a municipality, in SWANCC, the land at issue was
    GILA RIVER INDIAN CMTY . V . UNITED STATES             61
    only a “municipal landfill,” and yet the Supreme Court still
    determined that the federal government’s attempt to regulate
    this land constituted “a significant impingement of the States’
    traditional and primary power.” Id. at 173–74 (emphasis
    added). Moreover, as discussed below, it is Arizona’s state-
    wide zoning scheme created under Arizona state law (a
    scheme that allows cities to develop and lay claim to land
    enclosed within a cities corporate limits, even if that land is
    not incorporated) that will be interrupted by the Secretary’s
    application of the Gila Bend Act in this case. It is Arizona
    state citizens that will be affected by Parcel 2 being taken into
    trust just across the street from their neighborhoods. It is also
    land located within Arizona’s “own territory” that will be
    effectively transferred to another sovereign. Green v. Biddle,
    
    21 U.S. at 43
    . Even the Federal Government’s brief
    recognizes that “jurisdiction over Indian lands involves ‘an
    accommodation between the interests of the Tribes and the
    federal government, on the one hand, and those of the State,
    on the other.’” Federal Appellees’ Answering Br. 48
    (emphasis added) (quoting Nevada v. Hicks, 
    533 U.S. 353
    ,
    361-62 (2001)). The Federal Government’s brief also notes
    that the Secretary’s decision to take Parcel 2 into law will
    result in a “[d]isplacement of state law . . . .” Id. at 50
    (emphasis added).
    The majority’s argument that Arizona never “articulated
    a state sovereignty or constitutional interest vis-a-vis § 6(d)”
    also “puzzled” me. Maj. Op. 29–30. Arizona clearly argued
    (multiple times throughout both the opening and reply brief)
    that the Gila Bend Act, which includes Section 6(d), “as
    applied violates the Tenth Amendment” and invades
    “essential attributes inhering in [Arizona’s] sovereign status.”
    Arizona Appellants’ Opening Br. 49, 51. All parties were
    also ordered by our panel to discuss the application of the
    62      GILA RIVER INDIAN CMTY . V . UNITED STATES
    federalism clear statement rule to this case at oral argument,
    at which time Arizona argued that the clear statement rule
    specifically applies to an interpretation of Section 6(d), and
    state sovereignty concerns require construing any ambiguity
    in the Gila Bend Act in Arizona’s favor.17 I do not address
    Arizona’s argument that the Tenth Amendment and state
    sovereignty concerns create a substantive constitutional limit
    that prevents the Secretary from “tak[ing Parcel 2] into trust
    in the first place,” Arizona Appellants’ Reply Br. 27, nor do
    I address Arizona’s other concerns with the Gila Bend Act
    and the Secretary’s interpretation of it, because I conclude
    that the federalism canon’s procedural requirement for added
    clarity, as applied to Section 6(d)’s language alone, requires
    a ruling for Arizona and Glendale.
    Second, the statutory interpretation debate over the Gila
    Bend Act is over one interpretation that would significantly
    burden Arizona’s substantial state interests and another
    interpretation that is much less intrusive. The Secretary’s
    application of the Gila Bend Act would interfere with
    Arizona’s sovereign powers more than the typical creation of
    17
    It is worth noting that, in BFP, 
    511 U.S. 531
    , the Supreme Court
    invoked the clear statement canon in favor of the State despite the fact that
    neither the Ninth Circuit nor any party had discussed the clear statement
    rule. Our precedent is also clear that, even if Arizona did make a
    concession about a question of law, there is “no reason why we should
    make what we think would be an erroneous decision, because the
    applicable law was not insisted upon by one of the parties.” United States
    v. Miller, 
    822 F.2d 828
    , 832 (9th Cir. 1987) (quoting Smith Engineering
    Co. v. Rice, 
    102 F.2d 492
    , 499 (9th Cir.1938)). “The rule has been
    repeated in a variety of circumstances. Even if a concession is made by
    the government, we are not bound by the government’s ‘erroneous view
    of the law.’” 
    Id.
     (quoting Flamingo Resort, Inc. v. United States, 
    664 F.2d 1387
    , 1391 n. 5 (9th Cir.1982)). This is particularly true where all parties
    had the chance to address this issue at oral argument.
    GILA RIVER INDIAN CMTY . V . UNITED STATES            63
    an Indian reservation, regardless of whether a casino is ever
    actually built on Parcel 2. It is a commonsense conclusion
    that a state has a greater concern about how land within its
    cities is used than land outside its cities. SWANCC, 531 U.S.
    at 167, 171 (recognizing a heightened concern over land
    “wholly located within two Illinois counties” compared to
    land that “actually abutted on a navigable waterway”).
    Furthermore, ordinary land use concerns are heightened
    by the fact that in Arizona, municipalities expect to be able to
    “exercise a strong degree of control over zoning and
    development” over land within their geographic boundaries,
    even if the land is not incorporated. Carefree Improvement
    Ass’n, 
    649 P.2d at 987
    ; 
    Ariz. Rev. Stat. § 11-814
    (G). A city’s
    land-use planning documents and zoning ordinances are able
    to guide the zoning and subdivision of county islands.
    Carefree Improvement Ass’n, 
    649 P.2d at
    986–87, 992. In
    addition, in Arizona, generally no other municipality can
    annex unincorporated land such as Parcel 2 that is within a
    city’s geographic limits. 
    Id. at 986
    ; 
    Ariz. Rev. Stat. § 9-101.01
    ; see also Kane v. City of Beaverton, 
    122 P.3d 137
    ,
    142 (Or. Ct. App. 2005) (“[T]here are a number of rational
    and legitimate reasons for disparate treatment of ‘island’
    territories . . . .”). Thus, Glendale had reasonable
    expectations that it would be able to guide and control Parcel
    2’s development, and that this land could not be claimed by
    any other entity capable of changing the land use
    development. In reliance on this zoning scheme, the City of
    Glendale zoned Parcel 2 as residential and developed the
    surrounding area consistent with that zoning designation.
    These reliance interests would not exist to the same extent in
    the hypothetical the majority poses, regarding “acquiring land
    in trust immediately adjacent to a city’s outermost boundary
    64      GILA RIVER INDIAN CMTY . V . UNITED STATES
    or even land that was almost, but not entirely encircled by
    corporate land.”18 Maj. Op. 31.
    The State’s territorial control—the ability to tax, to
    regulate, and to control land use—is effectively eliminated
    when state land is taken into trust. As courts have noted,
    “federally-recognized reservations . . . are, in many ways,
    separate jurisdictions from the state in which they are
    located.” Tworek v. United States, 
    46 Fed. Cl. 82
    , 87 (2000).
    Importantly for this case, tribal sovereignty blocks “state
    action that impairs the ability of a tribe to exercise traditional
    governmental functions such as zoning . . . or the exercise of
    general civil jurisdiction over the members of the tribe.”
    Crow Tribe of Indians v. Montana, 
    650 F.2d 1104
    , 1110 (9th
    Cir. 1981) (emphasis added); see also Segundo v. City of
    Rancho Mirage, 
    813 F.2d 1387
    , 1390–94 (9th Cir. 1987)
    (rejecting a State’s attempts to apply local laws such as
    zoning ordinances to reservation lands). The Supreme Court
    has explained that one of the independent “barriers to the
    assertion of state regulatory authority over tribal reservations
    and members” is the sovereign “right of reservation Indians
    to make their own laws and be ruled by them.” White
    Mountain Apache Tribe v. Bracker, 
    448 U.S. 136
     (1980); see

    , 322 (1978)
    (“The powers of Indian tribes are, in general, inherent powers
    18
    Furthermore, the question of whether land immediately adjacent to
    Parcel 2 and outside Glendale’s city limits could be taken into trust is not
    a question before this court, given that it is not clear whether such land
    would meet other requirements of the Gila Bend Act, including that the
    land be “three separate areas consisting of contiguous tracts, at least one
    of which areas shall be contiguous to San Lucy Village,” Pub. L. No.
    99-503, § 6(d) 
    100 Stat. 1798
    , or else that non-contiguous parcels are
    “sufficiently close to be reasonably managed as a single economic unit or
    residential unit.” H.R. Rep. No. 99-851, at 11 (1986).
    GILA RIVER INDIAN CMTY . V . UNITED STATES                65
    of a limited sovereignty which has never been
    extinguished.”).       Thus, upholding the Secretary’s
    interpretation would strip Glendale of its long-standing
    authority to control land use on Parcel 2 and transfer that
    control to a separate sovereign.
    The transfer of Arizona’s sovereign authority, over land
    enclosed within one of its major cities, is a significant
    encroachment on Arizona’s state interests, regardless of how
    Parcel 2 is ultimately developed. Moreover, the fact that
    taking Parcel 2 into trust would create the very real potential
    that a new casino would be built across the street from a high
    school, a quarter-mile from churches, and within Glendale’s
    carefully developed residential area (where millions of dollars
    have been invested) understandably heightens the State’s
    concerns.
    Furthermore, not only would the Secretary’s decision
    affect the State’s ordinary land use powers, the agency’s
    decision here will likely implicate major budgetary decisions.
    For example, if a casino is built, city officials estimate that
    the casino complex will require Glendale to build significant
    additional infrastructure in the area (e.g., fire, police, etc.), as
    well as to spend millions of additional dollars of expenditures
    for public safety outlays. The Supreme Court has explained
    that “[f]ederalism concerns are heightened when, as in these
    cases, a federal court decree has the effect of dictating state
    or local budget priorities.” Horne v. Flores, 
    557 U.S. 433
    ,
    448 (2009).
    The political process justifications for the federalism clear
    statement rule are also particularly relevant here. In contrast
    to Garcia, “[i]n the factual setting of [this case] the internal
    safeguards of the political process” have not “performed as
    66     GILA RIVER INDIAN CMTY . V . UNITED STATES
    intended.” Garcia, 
    469 U.S. at 556
    . As discussed above, the
    text of the Gila Bend Act readily lends itself to an
    interpretation that would prevent any reservations from being
    created within the geographic boundaries of a city. Thus,
    when two of Arizona’s own representatives sponsored the
    Gila Bend Act in the House of Representatives, there was
    nothing from the text of the statute that would have alerted
    Arizona to the fact that it was consenting, through the
    political process, to legislation that would be adverse to its
    significant state interests. Indeed, the Arizona Supreme
    Court’s recent decision in Flagstaff Vending, 
    578 P.2d at 987
    ,
    as well as Arizona’s zoning ordinances discussing
    unincorporated territory “within the corporate limits,” 
    Ariz. Rev. Stat. § 9-461.11
    (A); 
    id.
     § 9-462.07(A), likely reinforced
    Arizona’s understanding that land like Parcel 2 would not be
    eligible to be taken into trust.
    To further complicate Arizona’s dilemma, when the
    Department of Interior was considering the Nation’s land-
    into-trust application, Arizona did not participate in this ex
    parte filing and had no way to formally do so. There was no
    public notification, no docket, no pleading schedule, and no
    hearing for interested parties. Opponents of the application
    who happened to be aware of the proceedings were able to
    submit arguments against the application by letter only, but
    they were not alerted when the Secretary filed amendments
    to its application. Thus, the statutory interpretation tools and
    facts of this case indicate that the ambiguity at issue in the
    “within the corporate limits” phrase was of the type that
    prevented Arizona from adequately protecting its state
    interests through the political process.
    Third and lastly, the Secretary’s interpretation here
    concerns the scope of its own authority to take this land into
    GILA RIVER INDIAN CMTY . V . UNITED STATES            67
    trust. While the Gila Bend Act clearly provides authority for
    the Secretary to take land into trust to create Indian
    reservations in certain locations, this grant of authority is
    based on significant limitations, including that such
    reservations not be created “within the corporate limits” of a
    city. The majority concedes that the Gila Bend Act is
    “ambiguous” regarding whether the “within the corporate
    limits” language was meant to authorize the Secretary’s
    action of taking Parcel 2 into trust. Maj. Op. 21. As in
    Gregory, SWANCC, and Gonzalez v. Oregon, courts should
    not defer to an agency’s interpretation of an ambiguous grant
    of authority when the interpretation buts up against the limit
    of the agency’s own authority. This is especially true where
    such an interpretation may also press the outer limits of
    Congress’s authority under the Indian Commerce Clause. See
    United States v. Lara, 
    541 U.S. 193
    , 205 (2004) (indicating
    that Congress could run up against “constitutional limits” if
    its Indian legislation “interfere[d] with the power or authority
    of any State”).
    Therefore, even assuming the Gila Bend Act is
    ambiguous, ambiguity of this nature can only be interpreted
    in a State’s favor. Though the majority is correct that this
    “case illustrates the nuances of our federalist system of
    government,” Maj. Op. 10, the majority misunderstands that
    Arizona’s sovereign interests must prevail in this case, and
    this court is precluded from applying Chevron deference to
    the Secretary’s interpretation. The majority’s decision to
    remand (and set the stage for unwarranted Chevron
    deference) eviscerates the very political protections on which
    the Supreme Court relied when it decided in Garcia that
    States can protect their sovereign interests through the
    political process.
    68     GILA RIVER INDIAN CMTY . V . UNITED STATES
    III.
    Because both the plain language of the Gila Bend Act and
    the canon of construction favoring a State’s interests
    requiring an interpretation of “within the corporate limits”
    contrary to that of the Secretary, I must respectfully dissent.
