The federal Indian Gaming Regulatory Act of 1988 requires states to negotiate in good faith with Indian tribes that seek to enter into Tribal-State compacts (agreements) for the conduct of Class III gaming. The content of these compacts varies from state to state and may vary from tribe to tribe. These compacts frequently provide for the allocation of criminal and civil jurisdiction between the state and the Indian Tribe for the enforcement of laws and regulations. Such issues as minimum standards for the operation of casinos and licensing requirements are normally addressed in a compact. All negotiated and signed compacts are sent to the U.S. Department of the Interior for approval and become effective as soon as they are published in the Federal Register.
