The Supreme Court has ruled Thursday, July 9, 2020, that Oklahoma prosecutors lack the authority to pursue criminal cases in a large chunk of eastern Oklahoma that remains an American Indian reservation. The case was argued by telephone in May because of the coronavirus pandemic. The case revolved around an appeal by a Native American man who claimed state courts had no authority to try him for a crime committed on reservation land that belongs to the Muscogee (Creek) Nation.
