Key Takeaways

  • California and Arizona federal cases are appealed to the Ninth Circuit.
  • The notice of appeal in a criminal case must be filed within 14 days under Fed. R. App. P. 4(b)(1).
  • Appellate jurisdiction over district court decisions comes from 28 U.S.C. § 1291.

The circuit and its composition

28 U.S.C. § 41 constitutes the thirteen judicial circuits. The Ninth includes Alaska, Arizona, California, Idaho, Montana, Nevada, Oregon, Washington, Guam, and Hawaii — which is why a case from the Southern District of California, the Central District of California, or the District of Arizona is heard in the Ninth Circuit.

Jurisdiction and the appeal deadline

The court of appeals has jurisdiction of appeals from all final decisions of the district courts under 28 U.S.C. § 1291. The appeal begins with a notice of appeal filed within 14 days after the judgment or order, or the government's notice of appeal, under Fed. R. App. P. 4(b)(1).

The appellate process

After the notice, the record is prepared, the parties brief, and the case is assigned to a three-judge panel. The panel reviews the preserved issues; most outcomes turn on the standard of review and what the record shows.
