Knighton v. Cedarville Rancheria of Northern Paiute Indians, No. 17-15515 (9th Cir. 2019)Annotate this Case
The Ninth Circuit affirmed the district court's dismissal of an action challenging a tribal court's subject matter jurisdiction over tort claims brought by the tribe against a nonmember employee. The panel previously held that a tribe's inherent sovereign power to exclude nonmembers from tribal land is an independent source of regulatory power over nonmember conduct on tribal land.
In this case, the panel held that a tribe's regulatory power over nonmembers on tribal land does not solely derive from an Indian tribe’s exclusionary power, but also derives separately from its inherent sovereign power to protect self government and control internal relations. The panel held that the tribal court has jurisdiction over the tribe's claim under the circumstances presented here, given the existence of regulatory authority, the sovereign interests at stake, and the congressional interest in promoting tribal self-government. The panel held that the tribe has authority to regulate the nonmember employee's conduct at issue pursuant to its inherent power to exclude nonmembers from tribal lands, and in the alternative, the tribe has regulatory authority over the nonmember employee's conduct under both Montana exceptions.
