In this project, librarians and developers will partner with Native Nations to publish their laws open access and incorporate them into digital library collections.
Tribal constitutions and codes are the heart of self-government for over 500 federally recognized tribes, and are the lifeblood of Indian sovereignty. Each tribal government operates according to its own constitutional rules. Most tribes have written constitutions. Many of the constitutions are modeled on form constitutions provided by the United States Department of the Interior pursuant to the Indian Reorganization Act of 1934.
Tribal courts are courts of general jurisdiction, operating within federal Indian law and under jurisdiction conferred by tribal law.
