Rh and with being an accessory to the same.

In state trial court, Herrera asserted that he had a protected right to hunt where and when he did pursuant to the 1868 Treaty. The court disagreed and denied Herrera’s pretrial motion to dismiss. See Nos. CT–2015–2687, CT–2015–2688 (4th Jud. Dist. C. C., Sheridan Cty., Wyo., Oct. 16, 2015), App. to Pet. for Cert. 37, 41. Herrera unsuccessfully sought a stay of the trial court’s order from the Wyoming Supreme Court and this Court. He then went to trial, where he was not permitted to advance a treaty-based defense, and a jury convicted him on both counts. The trial court imposed a suspended jail sentence, as well as a fine and a 3-year suspension of Herrera’s hunting privileges.

Herrera appealed. The central question facing the state appellate court was whether the Crow Tribe’s off-reservation hunting right was still valid. The U. S. Court of Appeals for the Tenth Circuit, reviewing the same treaty right in 1995 in Crow Tribe of Indians v. Repsis, had ruled that the right had expired when Wyoming became a State. 73 F. 3d, at 992–993. The Tenth Circuit’s decision in Repsis relied heavily on a 19th-century decision of this Court, Ward v. Race Horse, 163 U. S. 504, 516 (1896). Herrera argued in the state court that this Court’s subsequent decision in Minnesota v. Mille Lacs Band of Chippewa Indians, 526 U. S. 172 (1999), repudiated Race Horse, and he urged the Wyoming court to follow Mille Lacs instead of the Repsis and Race Horse decisions that preceded it.

The state appellate court saw things differently. Reasoning that Mille Lacs had not overruled Race Horse, the court held that the Crow Tribe’s 1868 Treaty right expired upon Wyoming’s statehood. No. 2016–242 (4th Jud. Dist., Sheridan Cty., Wyo., Apr. 25, 2017), App. to Pet. for Cert. 31–34. Alternatively, the court concluded that the Repsis Court’s judgment merited issue-preclusive effect against
