25 U.S. Code § 458aaa - Definitions
The term “gross mismanagement” means a significant, clear, and convincing violation of a compact, funding agreement, or regulatory, or statutory requirements applicable to Federal funds transferred to an Indian tribe by a compact or funding agreement that results in a significant reduction of funds available for the programs, services, functions, or activities (or portions thereof) assumed by an Indian tribe.
The term “inherent Federal functions” means those Federal functions which cannot legally be delegated to Indian tribes.
The term “inter-tribal consortium” means a coalition of two  more separate Indian tribes that join together for the purpose of participating in self-governance, including tribal organizations.
The term “self-governance” means the program of self-governance established under section 458aaa–1 of this title.
In any case in which an Indian tribe has authorized another Indian tribe, an inter-tribal consortium, or a tribal organization to plan for or carry out programs, services, functions, or activities (or portions thereof) on its behalf under this part, the authorized Indian tribe, inter-tribal consortium, or tribal organization shall have the rights and responsibilities of the authorizing Indian tribe (except as otherwise provided in the authorizing resolution or in this part). In such event, the term “Indian tribe” as used in this part shall include such other authorized Indian tribe, inter-tribal consortium, or tribal organization.
 So in original. Probably should be followed by “or”.
