On Tuesday, the Supreme Court heard argument in its latest foray into Indian treaty interpretation, Herrera v. Wyoming. The case concerns the persistence of the Crow Tribe’s hunting right in the 1868 Second Treaty of Fort Laramie. In an occasionally meandering argument, the Supreme Court repeatedly circled the three issues at the core of the case: issue preclusion, the implications of the court’s holding in its 1999 decision in Minnesota v. Mille Lacs Band of Chippewa Indians, and the meaning of the treaty term “unoccupied.”
