​​​​​​The legal institutions in Indian country revolve around four main entities: indigenous or traditional courts, general jurisdiction courts, appellate courts, and the Bureau of Indian Affair’s Code of Federal Regulation courts. The National Survey of Tribal Court Systems (NSTCS) is the first complete enumeration of tribal court systems operating in the United States and gathers administrative and operational information from tribal court systems, prosecutors’ offices, and indigent defense providers operating in the United States. The NSTCS helps fulfill BJS’s legislative mandate under the Tribal Law and Order Act of 2010 (TLOA; P.L. 111-211, 124 Stat. 2258 § 251(b)) to establish and implement a tribal crime data collection system.
