What does the 9th circuit of the US have control over?

The Ninth Circuit Court of Appeals has jurisdiction over federal appellate cases originating from nine western states, including California, Oregon, Washington, and Alaska, as well as territories like Guam and the Northern Mariana Islands. It reviews decisions made by federal district courts, as well as some federal administrative agencies, and its rulings can significantly influence federal law, particularly in areas such as Immigration, environmental regulations, and civil rights. The Ninth Circuit is the largest of the federal appellate courts, both in terms of geographic area and caseload.
