Wilkinson v. Confederated Tribes and Bands of the Yakima Indian Nation

Opinion summary

Etalia.ai summary of the majority opinion

The case involved a dispute over the jurisdiction of state and tribal authorities concerning fishing rights on the Yakima Indian Reservation. The Confederated Tribes and Bands of the Yakima Indian Nation challenged Washington State's authority to regulate fishing by non-Indians in waters within reservation boundaries. The Supreme Court held that states could exercise regulatory authority over non-Indian activities on reservations unless preempted by federal law or if it interfered with tribal self-government. In this instance, since there was no explicit congressional prohibition against state regulation, Washington had concurrent jurisdiction to enforce its conservation laws regarding non-Indians fishing within reservation waters.
