Answer
Congress has recognized the right of tribes to have a greater say over the development and implementation of federal programs and policies that directly impact on them and their tribal members. It did so by enacting two major pieces of legislation that together embody the important concepts of tribal self-determination and self-governance: The Indian Self-determination and Education Assistance Act of 1975, as amended (25 U.S.C. 450 et seq.) and the Tribal Self-Governance Act of 1994 (25 U.S.C. 458aa et seq.). Through these laws, Congress accorded tribal governments the authority to administer themselves the programs and services usually administered by the BIA for their tribal members. It also upheld the principle of tribal consultation, whereby the federal government consults with tribes on federal actions, policies, rules or regulations that will directly affect them.
