9th Circuit
The Ninth Circuit is a federal court of appeals that reviews decisions from district courts in nine western states, including California, Arizona, and Nevada. It is responsible for ensuring legal decisions comply with federal law and constitutional principles. As an appellate court, it doesn't conduct trials but reviews cases to determine if legal errors occurred. Its rulings can set important legal precedents and influence laws across its region. The Ninth Circuit is the largest of the thirteen U.S. courts of appeals, making it a significant player in the national judicial system.
