Opinion of the Court
Herrera because he is a member of the Crow Tribe, and the Tribe had litigated the Repsis suit on behalf of itself and its members. App. to Pet. for Cert. 15–17, 31; App. 258. Herrera, in other words, was not allowed to relitigate the validity of the treaty right in his own case.
The court also held that, even if the 1868 Treaty right survived Wyoming’s entry into the Union, it did not permit Herrera to hunt in Bighorn National Forest. Again following Repsis, the court concluded that the treaty right applies only on “unoccupied” lands and that the national forest became categorically “occupied” when it was created. See App. to Pet. for Cert. 33–34; Repsis, 73 F. 3d, at 994. The state appellate court affirmed the trial court’s judgment and sentence.
The Wyoming Supreme Court denied a petition for review, and this Court granted certiorari. 585 U. S. ___ (2018). For the reasons that follow, we now vacate and remand.

We first consider whether the Crow Tribe’s hunting rights under the 1868 Treaty remain valid. Relying on this Court’s decision in Mille Lacs, Herrera and the United States contend that those rights did not expire when Wyoming became a State in 1890. We agree.

Race Horse concerned a hunting right guaranteed in a treaty with the Shoshone and Bannock Tribes. The Shoshone-Bannock Treaty and the 1868 Treaty with the Crow Tribe were signed in the same year and contain identical language reserving an off-reservation hunting
