How Do I Find Tribal Law For Tribes Outside of Arizona?

Starting Out: Finding Background Information
You should begin your tribal law research project by first finding some background information about the tribe’s legal system. This will give you an idea about the types of primary sources you will need to locate:  constitutions, treaties, codes, court decisions, and customary or traditional law. Listed below are sources for this type of information.

United States Tribal Courts Directory

Provides state-by-state information on tribal courts including contacts, areas of jurisdiction and publication information for tribal opinions and codes.

Edited and compiled by Veronica E. Velarde Tiller
In addition to economic information on tribes includes useful information and statistics on land status, government, culture and history and infrastructure.

Finding the Text of Tribal Court Decisions

Indian Law Reporter and Cumulative Subject Index to the Tribal Court Cases
The Indian Law Reporter is a print publication of the American Indian Lawyer Training Program. It provides access to a selected set of court opinions and other materials related to Indian law, including those of tribal courts. While each volume has its own subject index, the publisher has yet to create a cumulative index to all of the volumes. NILL created a cumulative index just to the tribal court opinions; the index is available on the NILL website.

Northwest Intertribal Court System (NICS)
Provides an appellate court forum and appellate court opinions for Indian nations based in the Puget Sound region of the Pacific Northwest: Chehalis Confederated Tribes, Muckleshoot Tribe, Port Gamble SKlallam Tribe, Sauk-Suiattle Tribe, Shoalwater Bay Indian Tribe, Skokomish Tribal Nation, Stillaguamish Tribe of Indians, and The Tulalip Tribes. This resource is also available in print in the Law Library.
