In July 1895, a posse of non-Indians, mostly outfitters, attacked a peaceful band of Bannocks south of Jackson Hole. The Indians believed they were legally hunting elk. But in a surprise decision, the U.S. Supreme Court ruled that state law overrode their treaty rights. In 2019, in a case with huge implications for tribal sovereignty, the court finally upended that ruling. This case too was set in Wyoming, as a Crow Tribe member hunted elk in the Bighorn Mountains.
