Osage Nation fights for reservation recognition

A federal judge has granted the U.S. government until May 30 to file an amicus brief in Osage Nation’s legal battle over its reservation status. The tribe is challenging a 2009 ruling that declared its reservation disestablished, citing the Supreme Court’s 2020 McGirt decision. The Oklahoma Tax Commission opposes the move, arguing that vacating the ruling could have major tax implications. The case could impact tribal sovereignty, taxation, and law enforcement.
