In OCCA case No. F-2018-1268, Stewart Wayne Coffman appealed his conviction for First Degree Manslaughter. In an unpublished decision, the court decided to reverse the conviction and remand the case with instructions to dismiss it. One judge dissented. Coffman was found guilty of First Degree Manslaughter, and the judge sentenced him to forty years in prison. He appealed his conviction, claiming that the court did not have the right to try him because the victim, Joe Battiest, Jr., was a member of the Choctaw Nation and the crime took place in Indian Country. The case was affected by a past ruling, McGirt v. Oklahoma, which stated that crimes on certain Native American lands fall under federal jurisdiction. The appellate court ordered a hearing to investigate Coffman's claims about the victim’s status and the crime's location. During this hearing, experts confirmed that Battiest had a majority of Indian blood and was recognized by the Choctaw Nation. The crime took place at a specific address that was within the historical boundaries of the Choctaw Nation. The district court found no evidence that Congress had ever removed those boundaries. After reviewing the evidence, the court decided that Coffman's case should be dismissed because Oklahoma did not have jurisdiction to prosecute him, in line with the earlier McGirt decision. Therefore, the court reversed the judgments and sentences of the lower court, ordering the case dismissed.
