Final answer:
The U.S. Court of Appeals for the Ninth Circuit has no original jurisdiction, only appellate jurisdiction. Original jurisdiction is the authority to hear a case first, which U.S. District Courts and the Supreme Court in certain cases possess.
Step-by-step explanation:
According to the available information on the American Judicial System structure, the U.S. Court of Appeals for the Ninth Circuit, like other U.S. Courts of Appeals, has no original jurisdiction.
Original jurisdiction refers to the authority of a court to hear a case first, in its initial phase before any appeals. The U.S. Courts of Appeals, including the Ninth Circuit, solely exercise appellate jurisdiction, meaning they review the decisions of lower courts, such as the district courts, but they do not hear cases initially. The U.S. District Courts, such as the Eastern District of California and the Northern District of Ohio, have original jurisdiction over cases within their geographical area. In contrast, the Supreme Court has both original and appellate jurisdiction but has original jurisdiction in limited types of cases, such as those involving states or diplomats.
