Oneida Nation of New York v. City of Sherrill

In Oneida Nation of New York v. City of Sherrill (2005), the U.S. Supreme Court addressed whether the Oneida Nation could establish a sovereign, tribal-governed casino in Sherrill, NY, without violating state law. The Court ruled that the tribe's attempt to reassert ownership over land held for decades—through relocations—was considered a new land claim aimed at bypassing the 1795 land agreement. The Court emphasized that such claims threaten state sovereignty and the country's land use order, concluding the tribe's plan was not permitted under federal law, and that the land could be taxed and regulated by the state.
