The Tribal Self-Governance Act is a federal law enacted in 1994 that empowers Native American tribes to manage their own programs and services in a manner that aligns with their unique cultural and governance systems. This act allows tribes to enter into self-governance agreements with the federal government, providing them greater control over funding and operations while recognizing their sovereignty. By facilitating self-governance, this act strengthens tribal sovereignty and upholds treaty rights, allowing tribes to tailor programs according to their specific needs and values.
