Whether Wyoming’s admission to the Union extinguished the Crow Tribe’s 1868 treaty right to hunt on unoccupied federal lands.
Holding
No. Wyoming’s statehood did not abrogate the Crow Tribe’s treaty-protected hunting right.
Reasoning
Minnesota v. Mille Lacs Band of Chippewa Indians, rather than Ward v. Race Horse, controlled the analysis. Mille Lacs rejected the premise that treaty hunting rights necessarily conflict with a State’s sovereignty over wildlife. States may impose reasonable, nondiscriminatory conservation regulations when necessary, so a continuing treaty right is not inherently incompatible with statehood.
The Court clarified that Race Horse no longer has force insofar as it held that statehood may impliedly extinguish Indian treaty rights. Treaty rights survive unless Congress clearly expresses an intent to abrogate them or a termination condition specified in the treaty itself has occurred.
The Wyoming Statehood Act admitted Wyoming on an equal footing with other States but said nothing about Indian treaty rights. Because Congress must clearly show that it considered and chose to abrogate a treaty right, that silence could not terminate the Crow Tribe’s hunting right.
The treaty itself listed the conditions under which the hunting right would end: the land ceases to be unoccupied federal land, game disappears, or peace no longer exists at the borders of the hunting districts. Statehood is not among those conditions, and neither the treaty text nor the negotiating history suggests that the Crow Tribe would have understood statehood to end its right.
