Michigan v. Bay Mills Indian Community, 572 U.S. __ (2014), was a United States Supreme Court case examining if a federal court has jurisdiction over activity that violates the Indian Gaming Regulatory Act but which takes place off Indian lands, and, if so, does tribal sovereign immunity prevent a state from suing in federal court. In a 5-4 decision, the Court held that the State of Michigan's suit against Bay Mills is barred by tribal immunity.
