Antoine v. Washington, 420 U.S. 194 (1975), was a United States Supreme Court case in which the Court held that treaties and laws must be construed in favor of Native Americans (Indians); that the Supremacy Clause precludes the application of state game laws to the tribe; that Congress showed no intent to subject the tribe to state jurisdiction for hunting; and while the state can regulate non-Indians in the ceded area, Indians must be exempted from such regulations.
