After being remanded to determine if the regulations were not discriminatory, the case returned to the United States Supreme Court in "Department of Game of Washington v. Puyallup Tribe" ("Puyallyp II"). Again, Justice Douglas wrote the opinion for the Court, but this time he struck down the state restrictions as discriminatory. Douglas noted that the restrictions for catching steelhead trout with nets had remained, and was a method used only by the Indigenous peoples, whereas hook and line fishing was allowed but was used only by non-Indigenous people. As such, the effect of the regulation allocated all of the steelhead trout fishing to sport anglers, and none to the tribes.
