On July 9, 2020, the U.S. Supreme Court ruled 5-4 that Jimcy McGirt, a member of the Seminole, could not be tried in an Oklahoma court, because McGirt’s alleged crime occurred in territory reserved to the Creek under an 1833 treaty.  Aside from the impact on McGirt’s case, who could still be tried in federal court, the ruling has profound implications for the relationships between U.S. State governments and Native American nations.  Kirsten Carlson is a professor of Law and Political Science at Wayne State University, and she joined the Monday Buzz on July 27, 2020.
