Enrollment, membership, and due process

Reviewed against current law and federal sources, 2026.

Federal courts will not review who a tribe enrolls. Enrollment software is a system of record for the tribe's own rules, not a federal-compliance overlay.

Who decides membership

A tribe's power to define its own membership is, in the Supreme Court's words, central to its existence as an independent political community. In Santa Clara Pueblo v. Martinez (1978) the Court held that the Indian Civil Rights Act creates no federal cause of action to challenge a tribe's membership or governance decisions. Membership is a question of tribal law, decided in the tribe's own forum.

How criteria are set

Each tribe sets its own membership criteria by constitution or ordinance. The common approaches are lineal descent from a person on a base roll, a blood-quantum requirement, or a blend of the two. There is no uniform federal standard, so the rule is a tribe-configurable parameter, and the base roll is the immutable anchor record.

Because the criteria vary tribe to tribe, a system of record has to treat the enrollment rule as configurable, not fixed to one nation's formula.

The due process a tribe owes

The Indian Civil Rights Act bars a tribe from denying equal protection or depriving a person of liberty or property without due process (25 U.S.C. 1302(a)(8)). That floor is interpreted and enforced through the tribe's own court or administrative forum, since the sole federal remedy under the Act is habeas corpus (25 U.S.C. 1303). For enrollment and disenrollment, that means a clear process:

• Written notice of the action and its basis.
• A hearing before the tribe's court or an administrative forum.
• A route of appeal.
• A written decision on the record.

Per-capita payments and the required plan

When a tribe distributes gaming net revenues as per-capita payments, federal law requires a Revenue Allocation Plan approved by the Secretary of the Interior (25 U.S.C. 2710(b)(3)), implemented through 25 CFR Part 290. Making per-capita payments without an approved plan is a violation of the Indian Gaming Regulatory Act, enforceable by the Department of Justice or the National Indian Gaming Commission.

A compliant plan breaks down net-revenue uses to a total of 100 percent, protects minors and legally incompetent members, describes tax notice and withholding, sets eligibility, and establishes a tribal forum for disputes. Plan approval is a gating step in the distribution pipeline, not paperwork after the fact.
