United States District Court for the District of Wyoming


The United States District Court for the District of Wyoming is the Federal district court whose jurisdiction comprises the state of Wyoming and those portions of Yellowstone National Park situated in Montana and Idaho. The court has locations in Cheyenne and Casper.
Appeals from this court are heard by the United States Court of Appeals for the Tenth Circuit.
The United States Attorney's Office for the District of Wyoming represents the United States in civil and criminal litigation in the court. The current United States Attorney is Mark Klaassen.
The district of Wyoming is the only federal court district that includes portions of more than one state. Law professor Brian C. Kalt has argued that it may be impossible to impanel a jury in compliance with the Vicinage Clause of the Sixth Amendment for a crime committed solely in the Idaho portion of the park.
