Here, the Oklahoma Tax Commission is seeking review of a CA10 decision allowing a suit brought by the Osage Nation to proceed over sovereign immunity objections. Here is our post about the CA10 decision, with briefs and other materials. And here is the cert petition.

Here are the questions presented (from the petition):

1. May federal courts employ the doctrine of Ex parte Young, 209 U.S. 123 (1908), to permit suits by Indian tribes, otherwise barred by state sovereign immunity, that seek to establish sovereignty and jurisdiction over historical reservations, without taking into consideration the substantial impact of the relief on the sovereignty and jurisdiction long-exercised over such lands by states?

2. In view of this Court’s ruling in Idaho v. Coeur d’Alene Tribe of Idaho, 521 U.S. 261 (1997), and other decisions, may a federal court allow an Indian tribe’s suit – otherwise barred by the Eleventh Amendment – to proceed against state officers under the so-called “straightforward inquiry” used to determine the application of the Ex parte Young exception, when the relief would divest a state of substantial and long-exercised civil and criminal jurisdiction over its largest county?

3. Does a suit by an Indian tribe seeking a judicial determination that its historical reservation “remains” a present-day reservation involve the type of retrospective relief that cannot be pursued against state officers under the Ex parte Young exception to state sovereign immunity?
