The Fort Sill Apache Tribe opened the Warm Springs Casino near Lawton,
Oklahoma in 2022. Several miles away, the Comanche Nation operates its own
casinos—the Spur Casino and the Comanche Casino. The resulting competition
made the Nation’s casinos less profitable. Contending the Warm Springs Casino was

opened in violation of federal law, the Comanche Nation sued officials of the Fort
Sill Apache Tribe to enjoin operation of the casino. The Nation also seeks monetary
damages against the defendants in their individual capacities.
The Officials moved to dismiss the claims, raising tribal sovereign immunity.
The district court denied that motion to dismiss. The Officials appealed that ruling as
an immediately appealable order under the collateral-order doctrine.
Exercising our jurisdiction under 28 U.S.C. § 1291, we AFFIRM in part and
REVERSE in part. We conclude that the Indian Gaming Regulatory Act (IGRA)
abrogates the Tribe’s sovereign immunity defense, so the Nation can proceed with its
official-capacity claims under IGRA. But as to the official-capacity claims under the
Racketeer Influenced and Corrupt Organizations Act (RICO), we conclude that the
Officials are entitled to tribal immunity. As to the individual-capacity claims under
RICO, because we conclude that the Officials are the real parties in interest on the
damages claim, they are not entitled to raise tribal immunity.
I. Background
In 2022, the Fort Sill Apache Tribe opened the Warm Springs Casino, which is
located a few dozen miles from one of the Nation’s casinos. App. Vol. 2 at 18–19.
The Warm Springs Casino sits on a plot of land that the parties call the Tsalote
Allotment, which the Fort Sill Apache Tribe acquired in 2001. The Tsalote
Allotment is in the area formerly reserved to the Kiowa Tribe, Comanche Nation, and
3 Appellate Case: 24-6221 Document: 46-1 Date Filed: 04/21/2026 Page: 4
Apache Tribe. 1 But after Congress passed the General Allotment Act of 1887
(Dawes Act), ch. 119, 24 Stat. 388, the United States obtained much of the
reservation’s land and began allotting that land to individual claimants. 2 The United
States allotted one of those parcels to George Tsalote, a member of the Kiowa Tribe.
After the Fort Sill Apache Tribe acquired the Tsalote Allotment, the Bureau of
Indian Affairs deeded the land in trust for the Tribe, and the Tribe entered a gaming
compact with Oklahoma in 2005, but waited until 2022 to open Warm Springs.
The Nation sued for damages and an injunction halting operation of the Warm
Springs Casino. 3 The Nation named two groups of defendants: members of the
Tribe’s governing board and members of the Tribe’s gaming commission. 4 The
Nation sought injunctive and declaratory relief under IGRA and RICO against the
1 This refers to the Apache Tribe of Oklahoma, a tribe distinct from (though related to) the Fort Sill Apache Tribe. See App. Vol. 2 at 12–13. 2 The United States obtained this land through the Jerome Agreement, ch. 31 Stat. 676 (1900), signed in 1892 and ratified in 1900. This disestablished the KCA reservation. Tooisgah v. United States, 186 F.2d 93, 97–98 (10th Cir. 1950). 3 The Kiowa Tribe also joined the suit but has voluntarily dismissed its suit. App. Vol. 3 at 146. 4 The Nation also brought claims against various federal defendants—the Assistant Secretary for Indian Affairs, the Director of the Bureau of Indian Affairs, and the Chairman of the National Indian Gaming Commission. The district court dismissed these defendants. See App. Vol. 3 at 233–34.
4 Appellate Case: 24-6221 Document: 46-1 Date Filed: 04/21/2026 Page: 5
Officials in their official capacities, 5 and damages under RICO in their individual
capacities.
The Officials moved to dismiss the IGRA and RICO claims. As for the IGRA
claim, the Officials argued that the Nation failed to state a claim for relief under
Federal Rule of Civil Procedure 12(b)(6) and failed to join a required party under
Rule 12(b)(7). Relevant here, the Officials argued that the Tribe is a party required
to be joined in the suit but could not be joined because the Tribe’s sovereign
immunity protects it—and its officials—from suit. The court rejected that argument,
finding that the Tribe was not a required party since the Officials had been sued in
their official capacities. App. Vol. III at 249–50. The Officials made a similar
argument on the RICO claim. Invoking Rule 12(b)(6), they contended that tribal
immunity immunizes the Officials from suit, so that the official-capacity RICO claim
must fail. The court explicitly rejected the tribal-immunity argument on the RICO
claim. App. Vol. 3 at 252.
The Officials interlocutorily appealed under the collateral-order doctrine. See
Cohen v. Beneficial Indus. Loan Corp., 337 U.S. 541, 546–47 (1949).
II. Discussion The Officials contend they are protected by tribal sovereign immunity on the
official-capacity claims under IGRA and RICO. They also argue that they are
entitled to tribal immunity on the individual-capacity RICO claims because the Tribe
5 The district court dismissed the Nation’s other claim alleging a violation of the First Treaty of Medicine Lodge. See App. Vol. 3 at 256–57. 5 Appellate Case: 24-6221 Document: 46-1 Date Filed: 04/21/2026 Page: 6
is the real party in interest. The Nation counters that (1) IGRA abrogates tribal
immunity, (2) the RICO claim seeks injunctive relief against enforcement officials,
which displaces tribal immunity under Ex Parte Young, 209 U.S. 123 (1908), and (3)
the individual defendants are the real parties in interest, so they cannot raise the
Tribe’s immunity as a defense.
As we explain, we agree with the Nation that IGRA abrogates tribal immunity
on the IGRA claim and that the individuals are the real parties in interest. But we
agree with the Officials that Ex Parte Young does not displace tribal immunity on the
RICO claim.
A. Collateral-Order Jurisdiction
Before reaching the parties’ arguments, we have an obligation to ensure our
jurisdiction over the case before us. Shields Law Grp., LLC v. Stueve Siegel Hanson
LLP, 95 F.4th 1251, 1279 (10th Cir. 2024). Our jurisdiction over final decisions
from the district courts flows through 28 U.S.C. § 1291. See § 1291 (conferring
jurisdiction over “appeals from all final decisions of the district court”). As a general
matter, a decision is final—and thus appealable—only when it “ends the litigation on
the merits and leaves nothing for the court to do but execute the judgment.” Ray v.
Haluch Gravel Co. v. Cent. Pension Fund, 571 U.S. 177, 183 (2014) (quoting Catlin
v. United States, 324 U.S. 229, 233 (1945)).
But we may exercise interlocutory review over a special category of orders—
eligible collateral orders—despite the absence of a litigation-ending decision. Will v.
Hallock, 546 U.S. 345, 349 (2006) (characterizing the doctrine “not as an exception
6 Appellate Case: 24-6221 Document: 46-1 Date Filed: 04/21/2026 Page: 7
to the final decision rule laid down by Congress in § 1291, but as a practical
construction of it”). Under the collateral-order doctrine, we may review an order that
“(1) conclusively determine[s] the disputed question, (2) resolve[s] an important
issue completely separate from the merits, and (3) [is] effectively unreviewable on
appeal from a final judgment.” KCOM, Inc. v. Emp’rs Mut. Cas. Co., 829 F.3d 1192,
1199 (10th Cir. 2016). And though the class of orders meeting these requirements is
small, United States ex rel. Fiorisce, LLC v. Colo. Tech. Univ., Inc., 130 F.4th 811,
816 (10th Cir. 2025) (quoting Cohen, 337 U.S. at 546), an order denying tribal
sovereign immunity qualifies as a collateral order. See Breakthrough Mgmt. Grp.,
Inc. v. Chukchansi Gold Casino & Resort, 629 F.3d 1173, 1177 n.1 (10th Cir. 2010)
(citing Osage Tribal Council ex rel. Osage Tribe of Indians v. U.S. Dep’t of Labor,
187 F.3d 1179–80 (10th Cir. 1999)).
Thus, an order that explicitly denies tribal immunity qualifies as an
immediately appealable collateral order. Cf. Montoya v. Vigil, 898 F.3d 1056, 1063
(10th Cir. 2018) (explaining that “if the district court explicitly decided” the
immunity issue, then “we will usually have jurisdiction over the interlocutory
appeal”). But an order that implicitly denies tribal immunity qualifies, too. This
occurs when the defendant puts the immunity issue “clearly before” the court, and
“the district court’s silence” on the issue “operate[s] as an implicit denial.” Id.; see
also Lowe v. Town of Fairland, 143 F.3d 1378, 1380 (10th Cir. 1998) (agreeing with
7 Appellate Case: 24-6221 Document: 46-1 Date Filed: 04/21/2026 Page: 8
circuits that “conclude[] that orders failing or refusing to consider” immunity are
“immediately appealable”). 6
The order here explicitly denied tribal immunity on the RICO claim and
implicitly denied it on the IGRA claim. The court explicitly denied tribal immunity
on the RICO claim when, in response to the Officials’ tribal-immunity argument, it
declined to “dismiss the claim on this basis.” See App. Vol. 3 at 252 The court also
implicitly denied immunity on the IGRA claim. The Officials brought the issue
before the court by raising the immunity in their motion to dismiss. See App. Vol. 2
at 261 (“Tribal officials are immunized from suits brought against them because of
their official capacities.” (emphasis added)); id. (titling sections “THE FSAT IS
IMMUNE FROM SUIT” and “The FSAT has not Waived Sovereign Immunity and
the Ex parte Young Exception Does Not Apply”); id. at 262 (characterizing IGRA
claim as an attempt to “circumvent the sovereign immunity of the FSAT”). And with
the tribal-immunity issue before the court, the court’s silence on the issue operated as
an implicit denial of the Officials’ sovereign immunity against the IGRA claim. 7
6 To be sure, we have applied this implicit-denial rule most commonly in the qualified-immunity context. But the rule’s logic does not depend on the type of collateral order; it instead addresses what constitutes a denial of an issue that would give rise to a collateral order. 7 We acknowledge that the Officials raised the sovereign-immunity issue in the context of a Rule 12(b)(7) argument. So we cannot fault the district court for confining itself to the required-joinder analysis. But we think the Officials’ discussion of the Tribe’s immunity and their assertion that tribal officials are immune from suit sufficiently put the issue before the court, so that its silence on the issue operated as an implicit denial.
8 Appellate Case: 24-6221 Document: 46-1 Date Filed: 04/21/2026 Page: 9
Because the court’s order denied tribal immunity on the IGRA and RICO
claims, we have jurisdiction under the collateral-order doctrine.
B. Tribal Sovereign Immunity
Indian tribes exercise “inherent sovereign authority” as “domestic dependent
nations.” Michigan v. Bay Mills Indian Cmty., 572 U.S. 782 (2014). And though
Congress has broad legislative authority “in respect to Indian tribes,” tribes remain
“separate sovereigns pre-existing the Constitution.” Id. Thus, tribes retain certain
aspects of their sovereignty, one of which is sovereign immunity—the “common-law
immunity from suit traditionally enjoyed by sovereign powers.” Santa Clara Pueblo
v. Martinez, 436 U.S. 49, 56 (1978).
Tribal sovereign immunity is not limited to suits nominally against an Indian
tribe itself. The immunity also extends to suits against tribal officials—like the
Officials here—for claims against the officials in their official capacities. Native Am.
Dist. v. Seneca-Cayuga Tobacco Co., 546 F.3d 1288, 1296 (10th Cir. 2008) (“[A]
tribe’s immunity generally immunizes tribal officials from claims made against them
in their official capacities.” (citing Fletcher v. United States, 116 F.3d 1315, 1324
(10th Cir. 1997)). That is because “relief sought nominally against an officer is in
fact against the sovereign if the decree would operate against the latter.” Id. (quoting
Pennhurst State Sch. & Hosp. v. Halderman, 465 U.S. 89, 101 (1984)).
But tribal immunity does not attach to all suits. A tribe may, for example,
waive its immunity from suit. See Miner Elec., Inc. v. Muscogee (Creek) Nation, 505
F.3d 1007, 1011 (10th Cir. 2007). Or Congress may abrogate the tribe’s immunity by
9 Appellate Case: 24-6221 Document: 46-1 Date Filed: 04/21/2026 Page: 10
statute. Lac du Flambeau Band of Lake Superior Chippewa Indians v. Coughlin, 599
U.S. 382, 387 (2023). Alternatively, a plaintiff may rely on Ex Parte Young to
circumvent tribal immunity. Norton v. Ute Indian Tribe of the Uintah & Ouray
Rsrv., 862 F.3d 1236, 1251 (10th Cir. 2017). As we have explained, Ex Parte Young,
which allows a plaintiff to avoid a state’s sovereign immunity for “suits against state
officials seeking to enjoin alleged ongoing violations of federal law,” applies equally
to a tribe’s sovereign immunity. Crowe & Dunlevy, P.C. v. Stidham, 640 F.3d 1140,
1154–55 (10th Cir. 2011).
To abrogate tribal immunity, Congress must make its intent to abrogate
“unmistakably clear in the language of the statute.” Lac du Flambeau Band of Lake
Superior Chippewa Indians, 599 U.S. at 387. And under Ex Parte Young, a plaintiff
need only “seek[] to enjoin alleged ongoing violations of federal law” by suing
government officials directly. Crowe & Dunlevy, 640 F.3d at 1154.
Here, the Officials have invoked tribal immunity against Comanche Nation’s
official-capacity claims under IGRA and RICO. The Nation aims to defeat that
immunity through two of the exceptions mentioned above—abrogation and Ex Parte
Young. The Nation argues that (1) IGRA has abrogated tribal immunity on the IGRA
claim, and (2) Ex Parte Young displaces tribal immunity on the RICO claim. We
agree with the first argument but reject the second.
1. Official-Capacity Claim under IGRA
Congress enacted IGRA in 1988 to allocate authority over Indian gaming
between states, tribes, and the federal government. See Bay Mills, 572 U.S. at 785
10 Appellate Case: 24-6221 Document: 46-1 Date Filed: 04/21/2026 Page: 11
(explaining that IGRA “creates a framework for regulating gaming activity on Indian
lands”). IGRA focuses solely on gaming operations on “Indian lands.” See 25
U.S.C. § 2710 (regulating class I, class II, and class III gaming “on Indian lands”);
1 Cohen’s Handbook of Federal Indian Law § 16.02 (2024) (“[IGRA] governs most,
but not all, gaming by Indian tribes on Indian lands in the United States.”). “Indian
lands” are either “all lands within the limits of any Indian reservation” or “any lands
title to which is . . . held in trust by the United States for the benefit of any Indian
tribe or individual.” 25 U.S.C. § 2703(4). 8
IGRA provides different regulatory requirements on gaming depending on the
“class” the gaming falls into. Class I covers traditional and social games carrying
minimal financial stakes; class II covers games of chance (like bingo); and class III is
a residual category covering all remaining gaming. Typical casino games and slot
machines fall under class III gaming. 9 Bay Mills, 572 U.S. at 792.
IGRA regulates class III most heavily and imposes an extensive framework for
allocating authority between the states and tribes. The primary feature of this
framework is the tribal-state compact, without which a tribe may not operate class III
gaming. 25 U.S.C. § 2710(d) (making class III gaming operations lawful only if they
are “conducted in conformance with a Tribal-State Compact entered into by the
8 “Indian lands” also covers lands not held in trust but “subject to restriction by the United States against alienation and over which an Indian tribe exercises governmental power.” 25 U.S.C. § 2703(4)(B). 9 The White Springs Casino also offers class II and class III gaming. 11 Appellate Case: 24-6221 Document: 46-1 Date Filed: 04/21/2026 Page: 12
Indian tribe and the State”). This compact requirement gives a shared role to both
Indian tribes and state governments in regulating gaming on Indian lands.
See 1 Cohen’s Handbook of Federal Indian Law § 16.05 (2024). These compacts
usually contain provisions addressing enforcement of the compact’s provisions,
waivers of tribal immunity against state-initiated actions, and revenue-sharing
provisions. Id. Another common clause, relevant to this case, is one that specifies
where the gaming may take place. Id.
IGRA also contains enforcement mechanisms. IGRA confers jurisdiction on
the federal district courts over “any cause of action initiated by a State or Indian tribe
to enjoin a class III gaming activity located on Indian lands and conducted in
violation of any Tribal-State compact.” 25 U.S.C. § 2710(d)(7)(A)(ii). This
provision “partially abrogates tribal sovereign immunity,” but only for cases that fall
within § 2710(d)(7)(A)(ii)’s terms. Bay Mills, 572 U.S. at 791. In Bay Mills, for
example, Michigan sued an Indian tribe because the tribe opened a casino off Indian
lands in violation of both IGRA and the tribal-state compact. Id. at 786–87. The
Supreme Court observed, however, that IGRA’s abrogation clause covered only
gaming operations “located on Indian lands,” and because Michigan’s suit challenged
“gaming activity off Indian lands,” the suit did not fall within IGRA’s abrogation
clause. Id. at 791.
Section 2710(d)(7)(A)(ii) thus breaks down into four elements: (1) the suit
must be “initiated by a State or Indian tribe,” (2) “to enjoin a class III gaming
12 Appellate Case: 24-6221 Document: 46-1 Date Filed: 04/21/2026 Page: 13
activity,” (3) “located on Indian lands,” and (4) “conducted in violation of any
Tribal-State compact . . . that is in effect.” § 2710(d)(7)(A)(ii).
Here, the Nation argues that its suit meets each element of the abrogation
clause. We agree.
The first element of § 2710(d)(7)(A)(ii) focuses on who brings suit. And the
Officials argue that § 2710(d)(7)(A)(ii)’s language only encompasses suits brought
by Indian tribes that are parties to the tribal-state compact. But § 2710(d)(7)(A)(ii) is
not so limited. By its plain terms, the provision abrogates immunity when the suit is
“initiated by a State or Indian tribe” (and the other elements are met).
§ 2710(d)(7)(A)(ii). That language does not limit the abrogation clause only to those
suits brought by tribes that are parties to a compact; its plain language is broader than
that, including suits brought by “a[n] . . . Indian tribe.” Id. Nothing qualifies “Indian
tribe,” let alone something like “that is party to the compact.” So under the clause’s
plain language, it makes no difference which tribe brings suit, only that some tribe
with standing brings suit.
Given that plain language, “our inquiry is at an end.” Woods v. Standard Ins.,
771 F.3d 1257, 1265 (10th Cir. 2014) (citing United States v. Ron Pair Enters., Inc.,
489 U.S. 235, 241 (1989)); Carcieri v. Salazar, 555 U.S. 379, 387 (2009) (“This case
requires us to apply settled principles of statutory construction under which we must
first determine whether the statutory text is plain and unambiguous. If it is, we must
apply the statute according to its terms.” (citation omitted)). To be sure, Congress
“must make its intent . . . ‘unmistakably clear in the language of the statute.’” Lac du
13 Appellate Case: 24-6221 Document: 46-1 Date Filed: 04/21/2026 Page: 14
Flambeau Band of Lake Superior Chippewa Indians, 599 U.S. at 388 (quoting Fin.
Oversight & Mgmt. Bd. for P.R. v. Centro de Periodismo Investigativo, Inc., 598 U.S.
339, 346 (2023)). We thus apply a clear-statement rule to statutory text perceived to
abrogate tribal immunity. Id. And under that clear-statement rule, “‘if there is a
plausible interpretation of the statute’ that preserves sovereign immunity, Congress
has not unambiguously expressed the requisite intent.” Id. (quoting FAA v. Cooper,
566 U.S. 284, 290 (2012)).
Still, this clear-statement rule does not “displac[e] the other traditional tools of
statutory construction,” FAA, 566 U.S. at 291 (alteration in original) (quoting Richlin
Sec. Serv. Co. v. Chertoff, 553 U.S. 571, 589 (2008)), so all that is required is that the
abrogation be “clearly discernable from the statutory text in light of traditional
interpretive tools.” Id. 10 But one “cardinal” component of those traditional tools—
one that we turn to “before all others”—is that “a legislature says in a statute what it
means and means in a statute what it says there. When the words of a statute are
unambiguous, then, this first canon is also the last: ‘judicial inquiry is complete.’”
Conn. Nat. Bank v. Germain, 503 U.S. 249, 253–54 (1992) (citations omitted)
10 FAA addressed waivers of federal sovereign immunity, but the Supreme Court has adopted FAA’s clear-statement principles in the tribal-immunity context. See Lac du Flambeau Band of Lake Superior Chippewa Indians, 599 U.S. at 388. 14 Appellate Case: 24-6221 Document: 46-1 Date Filed: 04/21/2026 Page: 15
(quoting Rubin v. United States, 449 U.S. 424, 430 (1981)). The abrogation clause’s
plain meaning is dispositive.
Because § 2710(d)(7)(A)(ii)’s plain language abrogates immunity for “any
cause of action initiated by a[n] . . . Indian tribe,” we hold that a suit brought by an
Indian tribe with a plausible injury—whether a party to the tribal-state compact or
not—satisfies the first element of § 2710(d)(7)(A)(ii)’s abrogation clause. And
because the Nation’s claim is brought by an Indian tribe, it satisfies the abrogation
clause’s first element.
The Nation’s claim likewise satisfies the abrogation clause’s remaining
elements. The parties do not dispute that the Warm Springs Casino conducts class III
gaming, so the Nation’s suit seeks to enjoin a class III gaming activity. 11 Instead, the
parties focus their attention on (1) whether the Warm Springs Casino is on Indian
land, and (2) whether the Nation challenges the violation of a tribal-state compact.
The Officials argue that the Warm Springs Casino is not on Indian lands. But
the Nation and Officials’ dispute appears to be less about whether the Tsalote
Allotment is on Indian lands than about whose Indian lands the Allotment is on. See
Reply Br. at 11 (“[T]he Tsalote Allotment is the Fort Sill Apache Tribe’s Indian
11 In the reply brief, the Officials argue that the Nation’s suit fails the second element because its injunction would enjoin both class II and class III operations since the casino performs both. But the Officials raised the argument for the first time in their reply brief—and in conclusory fashion at that. We therefore decline to reach this issue. See 3484, Inc. v. NLRB, 137 F.4th 1093, 1113 (10th Cir. 2025) (finding an issue raised for the first time in a reply brief waived).
15 Appellate Case: 24-6221 Document: 46-1 Date Filed: 04/21/2026 Page: 16
lands.”); Appellee Br. at 27 (“[T]he Tsalote Allotment is ‘Indian lands’ under any
scenario.”). The Nation’s complaint alleged that “[t]he Tsalote Allotment is ‘Indian
land,’ but is not the FSA Tribe’s Indian land.” App. Vol. 2 at 27. The Nation says
that the Tsalote Allotment is Kiowa lands. And the Officials concede that the Tsalote
Allotment is Indian lands. See Appellant Br. at 3; Reply Br. at 11. So regardless of
whose Indian lands they are, the Tsalote Allotment remains Indian lands. 12
The Officials also argue that the Nation’s suit does not challenge a violation of
a tribal-state compact. The Fort Sill Apache Tribe–Oklahoma gaming compact
features a provision restricting where the Tribe may conduct gaming. It provides that
“[t]he tribe may establish and operate enterprises and facilities that operate covered
games only on its Indian lands as defined by IGRA.” App. Vol. 2 at 163 (emphasis
added). The Nation’s IGRA claim targets that provision: it argues that the Tribe is
operating the White Springs Casino on Kiowa lands, not on its own lands. The
Officials counter that the White Springs Casino rests on Fort Sill Apache Tribe lands,
not Kiowa lands.
We conclude that the Nation’s suit challenges a violation of the Tribe–
Oklahoma gaming compact. The Officials sidestep the relevant inquiry—whether the
12 The Officials argue that Indian trust lands must be land held in trust for the tribe. And because Kiowa tribe “relinquished any claim it had” to the Allotment, the lands cannot be Indian lands under the Nation’s theory. Reply Br. at 9. But that ignores IGRA’s definition of Indian lands, which covers “any lands title to which is . . . held in trust by the United States for the benefit of any Indian tribe or individual.” 25 U.S.C. § 2703(4)(B) (emphasis added).
16 Appellate Case: 24-6221 Document: 46-1 Date Filed: 04/21/2026 Page: 17
Nation’s claim challenges the violation of the location provision—and invites us to
conclude on the merits that the Tsalote Allotment is actually the Tribe’s lands. See
Reply Br. at 11 (explaining that the Tsalote Allotment is the Tribe’s land and calling
the Nation’s argument to the contrary “completely baseless”). But this case comes to
us on a motion to dismiss, and we are bound to accept well-pleaded allegations as
true and draw reasonable inferences in the Nation’s favor. See Pueblo of Jemez v.
United States, 790 F.3d 1143, 1147–48 (10th Cir. 2015).
The Nation’s complaint alleges that the Allotment was originally held in trust
for George Tsalote, a member of the Kiowa tribe, App. Vol. 2 at 11, rendering it an
“original Kiowa allotment,” App. Vol. 2 at 12. The complaint further alleges that the
Tribe purchased the Allotment, and “the BIA deeded the land in trust to the FSA
Tribe.” App. Vol. 2 at 16. But, the Nation alleges, this transfer was invalid—void
and without effect—because the “Tribe did not validly acquire the Tsalote
Allotment.” App. Vol. 2 at 27. So according to the Nation, the Tsalote Allotment
remains Kiowa lands, not Fort Sill Apache Tribe lands, and thus operating the casino
there “violates the FSA Tribe’s tribal-state compact with Oklahoma.” App. Vol. 2 at
27. We think those allegations challenge a violation of the Tribe’s gaming compact
with Oklahoma.
The Nation’s IGRA claim is a cause of action initiated by an Indian tribe to
enjoin a class III gaming operation on Indian land conducted in violation of a gaming
compact. The claim therefore falls within § 2710(d)(7)(A)(ii), and that provision
17 Appellate Case: 24-6221 Document: 46-1 Date Filed: 04/21/2026 Page: 18
abrogates the Tribe’s tribal immunity against the claim. Tribal immunity does not
protect the Officials from the Nation’s IGRA claim.
2. Official-Capacity Claim under RICO
The Nation next argues that Ex Parte Young displaces tribal immunity for its
RICO claim, which seeks injunctive and declaratory relief. Although Ex Parte Young
applies most often to state sovereign immunity, we also apply the doctrine to tribal
immunity. Crowe & Dunlevy, 640 F.3d at 1154–55 (10th Cir. 2011) (“[W]e join our
sister circuits in expressly recognizing Ex parte Young as an exception not just to
state sovereign immunity but also to tribal sovereign immunity.”). The Ex Parte
Young doctrine permits a plaintiff to circumvent tribal sovereign immunity by
“seeking to enjoin alleged ongoing violations of federal law.” Norton, 862 F.3d at
1251 (quoting Crow & Dunlevy, 640 F.3d at 1154). The exception applies to suits
against tribal officials, not against the tribal entity. Id. (finding Ex Parte Young
inapplicable because the “complaint asserts claims against those tribal entities rather
than their constituent officials”).
To determine whether Ex Parte Young applies, the court “need only conduct ‘a
straightforward inquiry’” into (1) whether the “complaint alleges an ongoing
violation of federal law,” and (2) whether the complaint “seeks relief properly
characterized as prospective.” Verizon Md., Inc. v. Pub. Serv. Comm’n of Md., 535
U.S. 635, 645 (2002) (quoting Idaho v. Coeur d’Alene Tribe of Idaho, 521 U.S. 261,
296 (1997)). But even where those two elements are met, Congress may have limited
the availability of an Ex Parte Young suit. That is so when Congress has enacted a
18 Appellate Case: 24-6221 Document: 46-1 Date Filed: 04/21/2026 Page: 19
“carefully crafted and intricate remedial scheme” to remedy the statutory violation.
Seminole Tribe of Fla. v. Florida, 517 U.S. 44, 74 (1996). And that limited relief
“display[s] an intent not to provide the ‘more complete and more immediate relief’
that would otherwise be available under Ex parte Young.” Verizon, 535 U.S. at 647
(quoting Seminole Tribe, 517 U.S. at 75)).
Ex Parte Young also requires that the plaintiff sue an official charged with
enforcing the challenged provision or engaging in challenged conduct. Kitchen v.
Herbert, 755 F.3d 1193, 1201 (10th Cir. 2014) (“Under Ex Parte Young, a state
defendant sued in his official capacity must ‘have some connection with the
enforcement’ of a challenged provision.” (quoting Ex Parte Young, 209 U.S. at 157));
Joseph A. ex rel. Wolfe v. Ingram, 275 F.3d 1253, 1260 (10th Cir. 2002) (describing a
proper Ex parte Young suit as “seek[ing] only prospective, injunctive relief against
state officers charged with carrying out the [challenged conduct]”).
The Nation seeks to enjoin the operation of the White Springs Casino, but it
has not alleged a connection between the Officials and the continuing operation of
the White Springs Casino. The Nation does not allege that the Officials “have a
particular duty to” operate the casino. Id. (citing Prairie Band Potawatomi Nation v.
Wagnon, 476 F.3d 818, 828 (10th Cir. 2007)). There are two groups of Officials
here: members of the Tribe’s governing board and members of the Tribe’s gaming
commission. At most, the Nation alleges that the Officials on the governing board
voted or approved the operation of the casino at some point in the past. See, e.g.,
App. Vol. 2 at 6 (“Ware is the Chairwoman of the Fort Sill Apache Tribe and is the
19 Appellate Case: 24-6221 Document: 46-1 Date Filed: 04/21/2026 Page: 20
official charged with supervising the affairs of the FSA Tribe and its business
committee.”); App. Vol. 2 at 7 (“Mann is . . . the official charged with . . . developing
proposals relating to implementing programs.”). Those allegations do not show a
connection to the continuing operation of the White Springs Casino. As for the
Officials on the gaming commission, the Nation only alleges that they “ensur[e]
compliance” with gaming laws. See App. Vol. 2 at 7–8. But having a duty to ensure
compliance is not the same as having a duty to operate the casino.
The Nation’s responses are unconvincing. It first argues that the Officials
waived their Ex Parte Young counterargument. But because tribal immunity raises a
jurisdictional issue, Miner Elec., Inc. v. Muscogee (Creek) Nation, 505 F.3d 1007,
1009 (10th Cir. 2007), we have an independent obligation to consider jurisdictional
defects. So we must consider whether Ex Parte Young applies, even if the Officials
did not raise the issue below. The Nation’s back-up argument is that it has “alleged
in detail” that the Officials have authority over the casino’s continuing operations.
But aside from the Nation’s allegations that some of the Officials hold compliance
authority, the Nation offers a general allegation that the Officials are “conspiring to
cause the Enterprise to open and operate an illegal gambling business.” App. Vol. 2
at 30. But those allegations do not address any particular duty or power that the
Officials have to operate the casino. See Chamber of Com., 594 F.3d at 760. The
Nation’s remaining allegation says that the “Fort Sill Apache Gaming
Commission . . . is the tribal entity charged with operating the Enterprise’s casino
gaming pursuant to IGRA.” App. Vol. 2 at 29 ¶ 106. But the complaint repeatedly
20 Appellate Case: 24-6221 Document: 46-1 Date Filed: 04/21/2026 Page: 21
alleges that the gaming commission “is the tribal entity charged with regulating the
FSA Tribe’s casino gaming pursuant to IGRA,” App. Vol. 2 at 7, and that the
commissioners are “charged with ensuring compliance with federal and state gaming
laws,” App. Vol. 2 at 7–8. So the natural reading of the Nation’s allegation in ¶ 106
is simply that the commission is charged with ensuring the casino is operated in
accordance with IGRA.
In short, Ex Parte Young does not help the Nation because its claims are not
against officials charged with operating the casino.
C. Individual-Capacity Claim under RICO
The Officials raise two arguments against the Nation’s individual-capacity
RICO claims: (1) these claims, though nominally against the Officials, are actually
against the Tribe, so tribal immunity still applies, and (2) if the claims are actually
against the Officials, then they are entitled to qualified immunity. We conclude that
the Officials cannot rely on tribal immunity because the tribe is not the real party in
interest—only the individual Officials are. And we are without jurisdiction to
consider the Officials’ qualified immunity because that issue formed no part of the
collateral order decided below.
The Nation’s RICO theory is that the Officials have conspired to operate the
Warm Springs Casino, which (they allege) constitutes a pattern of racketeering
activity consisting of illegal gambling and money laundering. See 18 U.S.C. § 1955
(illegal gambling); 18 U.S.C. §§ 1956, 1957 (money laundering).
21 Appellate Case: 24-6221 Document: 46-1 Date Filed: 04/21/2026 Page: 22
A suit challenging an official’s acts comes in two varieties: official-capacity
claims and individual-capacity claims. Both varieties name the individual officer as
defendant, but they are distinguished by who stands as the real party in interest—the
individual officer or the entity on whose behalf the individual acts. See Hafer v.
Melo, 502 U.S. 21, 25 (1991). In an official-capacity claim, the entity stands as the
real party in interest because official-capacity suits “generally represent only another
way of pleading an action against an entity of which an officer is an agent.”
Kentucky v. Graham, 473 U.S. 159, 165–66 (1985) (emphasis added) (quoting Monell
v. N.Y.C. Dep’t of Soc. Servs., 436 U.S. 658, 690 n.55 (1978)). And when the entity
is the real party in interest, the officer—though named as defendant—may raise the
immunities “that the government entity possesses.” Hafer, 502 U.S. at 25.
Conversely, when the officer himself is the real party in interest, then he may raise
“personal immunity defenses,” like qualified immunity. Lewis v. Clarke, 581 U.S.
155, 163 (2017). These rules apply equally in the tribal sovereign immunity context
and in the state sovereign immunity context. Id. (“There is no reason to depart from
these general rules in the context of tribal sovereign immunity.”).
To determine whether the Officials here can raise the Tribe’s immunity, we
ask whether the Tribe is “the real party in interest” because that “dictates what
immunities may be available” to the official. Id. The touchstone for the real-party-
in-interest inquiry is “who may be legally bound by the court’s adverse judgment.”
Id. at 165. We do not “simply rely on the characterization of the parties in the
complaint, but rather must determine in the first instance whether the remedy sought
22 Appellate Case: 24-6221 Document: 46-1 Date Filed: 04/21/2026 Page: 23
is truly against the sovereign.” Id. at 162 (citing Ex parte New York, 256 U.S. 490,
500–02 (1921)). And when a plaintiff seeks to impose “individual liability,” id. at
162, on the defendant for “his individual wrongdoing,” id. at 165–66, the judgment
binds the individual officer, not the tribe. Id. at 163 (explaining that judgment
against defendant for his personal actions “will not operate against the Tribe”). In
that scenario, the remedy is against the individual, not the tribe.
These principles foreclose the Officials’ reliance on the Tribe’s immunity.
The Nation seeks to impose individual liability on the Officials for individual acts
that they have taken in furthering an unlawful enterprise. The Officials themselves,
then, would be “legally bound by the court’s adverse judgment” regarding the RICO
claims, not the Tribe. That fact means that as far as the RICO claim goes, the
Officers—not the Tribe—are the real parties in interest. And because the Officers
are the real parties in interest, they cannot raise the Tribe’s sovereign immunity.
Recognizing this possible outcome, the Officials argue in the alternative that
they are entitled to qualified immunity. But we do not have jurisdiction under the
collateral-order doctrine to consider this issue. The Officials never raised qualified
immunity before the district court, so the district court neither explicitly nor
implicitly denied the Officials’ qualified immunity. No order denying qualified
immunity therefore provides an independent ground to exercise our collateral-order
jurisdiction in this case. Instead, our jurisdiction here arises from the court’s denial
of tribal immunity.
23 Appellate Case: 24-6221 Document: 46-1 Date Filed: 04/21/2026 Page: 24
When an appeal comes to us in this jurisdictional posture, our jurisdiction is
limited to reviewing (1) the court’s denial of tribal immunity and (2) “otherwise
nonfinal and nonappealable lower court decision[s] that overlap[] with an appealable
decision” over which we choose to exercise pendent jurisdiction. Moore v. City of
Wynnewood, 57 F.3d 924, 929 (10th Cir. 1995) (citing Snell v. Tunnell, 920 F.2d 673,
676 (10th Cir. 1990)). Qualified immunity, of course, is not tribal immunity, so the
court’s denial of tribal immunity does not encompass a denial of the Officials’
qualified immunity. And we will not invoke our pendent jurisdiction here—an
exercise that is “generally disfavored,” Cox v. Glanz, 800 F.3d 1231, 1255 (10th Cir.
2015) (quoting Armijo ex rel. Chavez v. Wagon Mound Pub. Sch., 159 F.3d 1253,
1264 (10th Cir. 1998)). 13 The Officials have not explained why we should exercise
our pendent jurisdiction; they simply encourage us to resolve qualified immunity “at
the earliest possible stage.” Appellant Br. at 31 (quoting Pearson v. Callahan, 555
U.S. 223, 232 (2009)). And they argue that qualified immunity cannot be waived.
But that conflates whether the Officials waived qualified immunity with whether we
have jurisdiction to review the issue.
In sum, because qualified immunity formed no part of the order below and we
decline to exercise pendent jurisdiction, we do not have jurisdiction to review the
issue of the Officials’ qualified immunity.
13 We also doubt whether we could exercise pendent jurisdiction over an issue never decided in the district court. Cox, 800 F.3d at 1231 (characterizing pendent jurisdiction as operating on “otherwise nonappealable decisions”). 24 Appellate Case: 24-6221 Document: 46-1 Date Filed: 04/21/2026 Page: 25
III. Conclusion For the forgoing reasons, we affirm in part and reverse in part.
