Another Oklahoma criminal case has potential jurisdiction implications for the Muscogee (Creek) Nation and other tribes in the state. The U.S. Supreme Court agreed the hear the case involving a Muscogee man who asserts he should have been tried in federal court rather than state district court because the crime happened within historical Creek boundaries. A decision potentially has far-reaching implications, not least of which are the hundreds of past convictions of Native citizens. It’s the second challenge of a criminal conviction on similar grounds. Last summer, the High Court delayed a decision and ordered new oral arguments in the case of a different Muscogee man arguing his death sentence is invalid because he was prosecuted in state court.
