25 U.S.C. § 5384: Compacts

The Secretary shall negotiate and enter into a written compact with each Indian tribe participating in self-governance in a manner consistent with the Federal Government’s trust responsibility, treaty obligations, and the government-to-government relationship between Indian tribes and the United States. Each compact required under subsection (a) of this section shall set forth the general terms of the government-to-government relationship between the Indian tribe and the Secretary, including such terms as the parties intend shall control year after year. Such compacts may only be amended by mutual agreement of the parties. retain the Tribal Self-Governance Demonstration Project compact of that Indian tribe (in whole or in part) to the extent that the provisions of that funding agreement are not directly contrary to any express provision of this subchapter; or instead of retaining a compact or portion thereof under paragraph (1), negotiate a new compact in a manner consistent with the requirements of this subchapter. The effective date of a compact shall be the date of the approval and execution by the Indian tribe or another date agreed upon by the parties, and shall remain in effect for so long as permitted by Federal law or until terminated by mutual written agreement, retrocession, or reassumption.
