Because of the diverse judicial cultures that reflect, in part, the various States and regions that compose the Federal judicial system, the instruments of Federal judicial administration are designed to accommodate this diversity. These include a national council of judges (the Judicial Conference of the United States), regional judicial councils, and the individual courts. This booklet thus describes the national, regional, and local elements of Federal judicial administration, as well as the agencies concerned with State-Federal judicial relations. Key administrative officials and agencies profiled at the national level are the Chief Justice of the United States, the Judicial Conference of the United States and its committees, the Administrative Office of the U.S. Courts, and the Federal Judicial Center. The regional and local governance components described in this booklet are the circuit, the chief judge of the circuit (chief judge of the circuit's court of appeals), circuit judicial councils, circuit executive, circuit judicial conference, chief district judge and district court, and chief bankruptcy judge and bankruptcy court. Regarding instruments of State-Federal judicial relations, State judges serve on the Federal-State Jurisdiction Committee of the Judicial Conference, which is primarily concerned with developing recommendations on legislation that affects State and Federal jurisdiction; it also promotes State-Federal judicial cooperation. 52 notes
