The Indian Gaming Regulatory Act, 25 U.S.C. § 2701 et seq. (IGRA), authorizes an Indian tribe to conduct class III gaming under limited circumstances and only on "Indian lands." 25 U.S.C. § 2710(d)(1). This dispute involves a federal court's authority to enjoin an Indian tribe from operating an illegal casino located off of "Indian lands." The petition presents two recurring questions of jurisprudential significance that have divided the circuits:
1. Whether a federal court has jurisdiction to enjoin activity that violates IGRA but takes place outside of Indian lands.
2. Whether tribal sovereign immunity bars a state from suing in federal court to enjoin a tribe from violating IGRA outside of Indian lands.
