The U.S. Court of Appeals for the Tenth Circuit is one of the thirteen federal appellate courts in the United States. It hears appeals from federal district courts in six states: Colorado, Kansas, New Mexico, Oklahoma, Utah, and Wyoming. The court's main role is to review decisions made by lower courts to ensure the law was applied correctly. Established in 1960, the Tenth Circuit is headquartered in Denver, Colorado. It consists of a panel of judges who evaluate cases involving federal law, including civil rights, immigration, and criminal matters. The court's decisions can be appealed to the U.S. Supreme Court.
