NOTE: The federal government has jurisdiction overcertain serious felonies committed on American Indian reservations, and a member of a tribe is vested with the rights of an American citizen even if in a tribal court proceeding. Prior to the IndianCivil Rights Act of 1968, states could obtain civil and criminal jurisdiction over a reservation or other American Indian lands by legislative action, but that Act created the requirement that suchjurisdiction be acquired with the consent of the tribe as manifest in an election among tribal adults. This requirement was not retroactive. Federal land claim settlement acts pertaining to particularstates have included statutes expressly assigning civil and criminal jurisdiction to the states involved.
