Michigan v. Bay Mills Indian Community, 572 U.S. 782 (2014), was a United States Supreme Court case examining whether a federal court has jurisdiction over activity that violates the Indian Gaming Regulatory Act but takes place off Indian lands, and, if so, whether tribal sovereign immunity prevents 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.
