Understanding Indigenous Law: Sovereignty and the Tribal-Federal Relationship

Indigenous law represents one of the most unique and dynamic areas within the American legal landscape. It is not simply a footnote in history; rather, it is a constantly evolving body of law encompassing inherent governmental powers, treaties, federal statutes, and judicial interpretations. For legal experts, policymakers, and citizens alike, grasping the fundamental distinctions between Indigenous Law and Federal Indian Law is crucial to understanding the contemporary status of America’s 574 federally recognized Tribal Nations.

Indigenous Law refers to the legal orders created by Indigenous Peoples themselves—their own customs, songs, stories, languages, and ceremonies that govern their communities, solve problems, and define their deep relationships to the land and water. These legal orders exist independently of state recognition. In contrast, Federal Indian Law is the body of federal legislation, treaties, judicial opinions, and executive orders that governs the relationship between the United States and the Tribal Nations within its borders. The two systems frequently intersect, sometimes harmoniously, sometimes contentiously.

The Three Pillars of Federal Indian Law

The entire framework of Federal Indian Law rests on three foundational principles that define the status and powers of Tribal Nations:

Historical Context: Key Legal Eras

The legal relationship between the U.S. and Tribal Nations has shifted through distinct historical policy eras, each shaping the current legal landscape:

Era	Time Period	Defining Legal Action
Treaty Making Era	1778–1871	Established a nation-to-nation political relationship, with the U.S. signing over 350 treaties.
Removal Era	1830–1850	Policies like the Indian Removal Act forced tribes from their eastern homelands to lands west of the Mississippi River, exemplified by the “Trail of Tears.”
Allotment & Assimilation Era	1887–1934	The General Allotment Act (Dawes Act) broke up communal reservation lands into individual parcels, resulting in the loss of nearly two-thirds of the tribal land base.

Tribal Justice Systems: Courts of Self-Governance

As sovereign entities, Tribal Nations maintain their own systems of justice, often referred to collectively as Tribal Courts or Tribal Justice Systems. These systems are integral to self-determination and can take several forms:

• Modern Tribal Courts: These systems are established directly under tribal authority, often modeled on constitutional forms of government, and are controlled by the tribe itself.
• Traditional/Customary Courts: Used by a smaller number of tribes, such as the Pueblos in the Southwest, these courts rely on unwritten, long-standing oral custom and tradition, with judicial functions often performed by tribal leaders or Elders. They prioritize restorative justice and community harmony.
• Courts of Indian Offenses (CFR Courts): These courts operate under federal law (Title 25 of the Code of Federal Regulations) and are subject to the Bureau of Indian Affairs (BIA). They provide justice services for tribes that have not yet established their own tribal court systems.

Summary: Navigating Legal Pluralism

Indigenous Law, in its broadest sense, is about legal pluralism—the recognition of multiple, co-existing legal orders within a single political space. For legal practitioners, this requires an understanding that every interaction with a Tribal Nation or its members is governed by a dynamic interplay of inherent tribal law and overarching federal policy.

Key Takeaways on Indigenous Law

1. Indigenous Law is the inherent, self-generated law of a Tribal Nation, distinct from Federal Indian Law, which is the body of U.S. law defining the federal-tribal relationship.
2. Tribal Sovereignty is inherent, not delegated, though it is subject to the Plenary Power of Congress.
3. The federal government operates under a Trust Responsibility to protect tribal interests and resources.
4. Tribal Courts (Modern, Traditional, and CFR) are the primary vehicles for tribal self-governance in justice, though their jurisdiction is constrained by federal acts like the Major Crimes Act and Public Law 280.
5. Landmark legislation like the Indian Child Welfare Act (ICWA) affirms the political relationship and the right of tribes to govern their most vital asset: their children.

Frequently Asked Questions (FAQ)

What is the difference between “Indigenous Law” and “Aboriginal Law”?

In the U.S. context, “Indigenous Law” (or “Tribal Law”) refers to the laws created by the Indigenous peoples themselves. “Aboriginal Law” is a term more commonly used in Canada to refer to the body of Canadian state law (legislation, common law) that affects Indigenous peoples. In the U.S., the equivalent state law body is often just referred to as a subset of Federal Indian Law or state-tribal relations law.

What is a “domestic dependent nation”?

It is the legal classification established by the Supreme Court for Tribal Nations. It recognizes their inherent sovereignty (“nation”) while noting their political relationship with and dependence on the United States government (“domestic dependent”).

Does the U.S. Constitution apply to Tribal Nations?

Generally, no. The U.S. Supreme Court has affirmed that because tribes pre-date the U.S. Constitution, its provisions, like the Bill of Rights, do not directly apply to tribal governments. However, the Indian Civil Rights Act (ICRA) of 1968 imposed certain limitations on tribal governments similar to, though not identical to, those found in the U.S. Constitution.

What is the role of treaties in modern Indigenous Law?

Treaties are foundational. They are considered the “supreme law of the land” alongside the U.S. Constitution and federal statutes. Treaties define the legal and political relationship, reserve rights for tribes (like hunting and fishing rights), and are key sources of the federal government’s trust responsibility.
