The US Supreme Court ruled that a huge chunk of Oklahoma, including much of Tulsa, falls within a Native American reservation.
The decision was a response to McGirt v. Oklahoma, in which Jimcy McGirt, a member of the Seminole Nation, was found guilty on the state level of a sex crime that happened within the Muscogee (Creek) Nation’s historical boundaries in 1997. McGirt argued that only federal authorities could prosecute him since state authorities have no power on Native American reservations.
