Holding: Wyoming’s statehood did not abrogate the Crow Tribe’s 1868 federal treaty right to hunt on the “unoccupied lands of the United States”; the lands of the Bighorn National Forest did not become categorically “occupied” when the forest was created.
Judgment: Vacated and remanded, 5-4, in an opinion by Justice Sotomayor on May 20, 2019. Justice Alito filed a dissenting opinion, in which Chief Justice Roberts and Justices Thomas and Kavanaugh joined.
