American Indian Law

American Indian Law research is complex and challenging. This guide covers U.S. statutes, tribal codes, case law, and secondary sources.

Finding Cases

There is no comprehensive publication for tribal opinions. Some opinions can be accessed through LexisNexis and Westlaw and found in the Indian Law Reporter and the Navajo Reporter. Some of the web sites listed under the Selected Research Guides tab also provide access to tribal court opinions and sites for individual tribes or nations sometimes include court opinions.

The Indian Law Reporter (ILR) is a publication of the American Indian Lawyer Training Program. While each volume has its own subject index, the publisher does not provide a cumulative index to all of the volumes. Because it is cumbersome to search each year's index separately, the National Indian Law Library (NILL) created this cumulative index of only the tribal court opinions for all volumes of the ILR. For more information on how to research tribal court opinions, please see the National Indian Law Library's guide to Tribal Court Opinion Research. --Description provided by NILL
