Indigenous Peoples Law
Tribal sovereignty, Indian law
Overview
Indigenous peoples' law, also called federal Indian law, governs the unique legal relationship between the United States and the federally recognized tribal nations. This relationship is rooted in the Constitution's Indian Commerce Clause and treaties between the U.S. and tribal nations. The federal trust responsibility obligates the government to protect tribal interests and resources.
Tribal sovereignty is the foundational principle of Indian law: tribes are sovereign nations with inherent authority to govern themselves, make laws, and adjudicate disputes. This sovereignty predates the Constitution and is recognized by the federal government, but it has been limited by Congress and court decisions. Federal statutes like the Indian Self-Determination Act promote tribal self-governance.
Key areas of Indian law include the Indian Child Welfare Act (governing custody and adoption of Native American children), the Indian Gaming Regulatory Act (establishing the framework for tribal casinos), tribal jurisdiction, water rights, and sacred sites protection. The Indian Civil Rights Act extends most Bill of Rights protections to tribal government actions.

State Variations
Indian law is primarily federal, but states interact with tribal sovereignty in significant ways. Public Law 280 transferred some federal criminal jurisdiction over Indian Country to six states. Tribal-state compacts govern gaming operations and revenue sharing. States differ on their recognition of tribal sovereignty for tax purposes, regulation, and law enforcement. Some states have their own state-recognized tribes with different legal status than federally recognized tribes.
Frequently Asked Questions
What is tribal sovereignty?
Tribal sovereignty is the inherent right of Native American tribes to govern themselves. Federally recognized tribes have government-to-government relationships with the U.S. and possess powers of self-governance including making laws, administering justice, and managing resources. This sovereignty is not granted by the federal government but is inherent, though it has been limited by federal law and court decisions.
How does the Indian Child Welfare Act work?
ICWA establishes federal standards for the removal and placement of Native American children. It requires that tribes be notified of state child custody proceedings involving tribal children, gives tribal courts jurisdiction over proceedings involving children domiciled on the reservation, and establishes placement preferences prioritizing the child's extended family, other tribal members, and other Indian families. The Supreme Court upheld ICWA's constitutionality in 2023.
