Key Points

  • IGRA's abrogation clause under 25 U.S.C. § 2710(d)(7)(A)(ii) applies to suits by any Indian tribe, not just tribes party to the challenged compact, per the panel's plain-language reading.
  • Ex parte Young does not displace tribal immunity for official-capacity RICO claims where the complaint fails to allege the officials have an enforcement connection to the casino's ongoing operation.
  • Individual-capacity RICO damages claims proceed because the officials, not the tribe, are the real parties in interest, though qualified immunity remains unreviewed for lack of jurisdiction.
  • The panel confirmed collateral-order jurisdiction extends to implicit denials of tribal immunity where the issue was clearly raised below and the district court stayed silent.

The Tenth Circuit on April 21 delivered a mixed ruling for officials of the Fort Sill Apache Tribe sued by the Comanche Nation over the Warm Springs Casino, holding that the Indian Gaming Regulatory Act abrogates tribal sovereign immunity for the Nation's official-capacity claim but that RICO does not reach the same officials in their official capacities.

Judge Tymkovich, writing for a panel that included Judges Hartz and Bacharach, affirmed the district court's denial of immunity on the IGRA claim and on the individual-capacity RICO claim, but reversed as to the official-capacity RICO claim, finding tribal immunity intact there.

The dispute traces to the 2022 opening of Warm Springs Casino near Lawton, Oklahoma, on land the parties call the Tsalote Allotment. The Comanche Nation, which operates nearby casinos, sued Fort Sill Apache Tribe governing-board and gaming-commission officials, alleging the casino sits on land originally allotted to a Kiowa tribal member rather than Fort Sill Apache land, in violation of the tribe's compact with Oklahoma.

The officials moved to dismiss on tribal-immunity grounds; the district court denied the motion, and the officials pursued an interlocutory appeal under the collateral-order doctrine, which the panel found proper because the district court had explicitly denied immunity on the RICO claim and implicitly denied it on the IGRA claim by staying silent after the issue was squarely raised.

On the merits, the panel read IGRA's abrogation provision, 25 U.S.C. § 2710(d)(7)(A)(ii), by its plain terms. The officials had argued the provision covers only suits by tribes that are parties to the relevant compact. The panel disagreed, reasoning that the statute's text abrogates immunity for any cause of action initiated by a state or Indian tribe, with no qualifier limiting that language to tribes that are party to the compact at issue.

Because the complaint plausibly alleged that the casino operates on Indian lands in violation of the Fort Sill Apache-Oklahoma compact's location provision, the panel held the suit satisfies every element of the abrogation clause and tribal immunity does not shield the officials from the IGRA claim.

The RICO claim fared differently. The Nation argued Ex parte Young let it sue the officials for injunctive relief despite tribal immunity, but the panel found no allegation that the named officials have any enforcement connection to the casino's ongoing operation, as opposed to a past vote to approve it or a general compliance role. The court stated:

"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."

On the individual-capacity RICO claim, the panel sided with the Nation, concluding the officials themselves are the real parties in interest for damages tied to their personal conduct, so they cannot borrow the tribe's immunity. The court declined to reach qualified immunity, however, because that defense was never raised below and thus fell outside the collateral order on appeal.

The decision gives gaming and tribal-litigation counsel a concrete marker: IGRA's abrogation clause reaches suits by any tribe meeting the statute's location and class-III elements, regardless of compact membership, while RICO claims against tribal officials in their official capacities still require a specific, ongoing enforcement link to survive an Ex parte Young challenge to sovereign immunity.
