The United States District Court for the Central District of California (in case citations, C.D. Cal.; commonly referred to as the CDCA or CACD) is a Federal trial court that serves over 19 million people in Southern and Central California, making it the most populous federal judicial district. The district was created on September 18, 1966. Cases from the Central District are appealed to the United States Court of Appeals for the Ninth Circuit (except for patent claims and claims against the United States government under the Tucker Act, which are appealed to the Federal Circuit). Along with the Central District of Illinois, the court is the only district court referred to by the name "Central" – all other courts with similar geographical names instead use the term "Middle."
