The case ruled over both the criminal and civil position of tribal government authority. Tribal governments do not have civil regulatory jurisdiction over non-Indian activities on fee lands or owned lands inside of tribal reservations. Tribes simply do not have full regulatory authority over non-Indians. Moreover, the Supreme Court is reading this case broadly stating that tribes do not have inherent jurisdiction over non-Indians civil matters at all although tribal governments may regulate hunting and fishing on trial lands. There are two exceptions in this ruling: 1. Citizens who enter into contracts with tribes are bound and under tribal jurisdiction. 2. Or the civil activity o non-Indian citizens threatens the political integrity of the tribal government or the health or security of the Indian government.
