Who governs a Native American tribe?

Indian Tribes are independent entities with powers of self-government that predate the establishment of the United States.  Michigan tribal casinos are operated under the authority of the Tribal-State Compacts mutually entered into between the Tribes and the State of Michigan, as well as the federal Indian Gaming Regulatory Act (IGRA).  The Michigan Tribal-State Compacts do not provide a resolution process for problems and issues that may arise between a patron and a tribal casino, i.e., a dispute over slot machine payouts or malfunctions.
