Summary: written with AI from the case record.

What it's about
The Supreme Court wiped out the Washington Supreme Court’s judgment and sent the case back (vacated and remanded), saying an earlier tax case did not decide whether tribal sovereign immunity applies in lawsuits over property.
The case involved tribal sovereign immunity and interpretation of the Indian General Allotment Act of 1887.
Question presented
Does a court's exercise of in rem jurisdiction overcome the jurisdictional bar of tribal sovereign immunity when the tribe has not waived immunity and Congress has not unequivocally abrogated it?
What the Court decided
Holding
Yakima addressed not the scope of tribal sovereign immunity, but a question of statutory interpretation of the Indian General Allotment Act of 1887. That Act authorized the President to allot parcels of reservation land to individual tribal members and directed the United States eventually to issue fee patents to the allottees as private individuals. In 1934, Congress reversed course but made no attempt to withdraw the lands already conveyed. As a result, Indian reservations sometimes contain both trust land held by the United States and fee-patented land held by private parties. Yakima concerned the tax consequences of this intermixture. 187 Wash. 2d 857, 389 P. 3d 569, vacated and remanded.
