he United States Supreme Court on Thursday recognized about half of Oklahoma as Native American reservation land and overturned a tribe member's rape conviction because the location where the crime was committed should have been considered outside the reach of state criminal law.

The justices ruled 5-4 in favor of a man named Jimcy McGirt and agreed that the site of the rape should have been recognized as part of a reservation based on the historical claim of the Muscogee (Creek) Nation – beyond the jurisdiction of state authorities.

Conservative Justice Neil Gorsuch joined the court's four liberals in the majority.

The ruling means that for the first time much of eastern Oklahoma is legally considered reservation land. More than 1.8 million people live in the land at issue, including roughly 400,000 in Tulsa, Oklahoma's second-largest city.
