Editing United States federal judge (section)

==Duty station==
Each federal judge serves at a particular "duty station" for the duration of their federal service. This is important because of the relationship among several federal statutes. First, 28 U.S.C. § 456(a) entitles federal judges to reimbursement of transportation and "subsistence" expenses incurred while transacting official business away from their duty stations. Section 456 also prescribes that the District of Columbia is the duty station of all members of the U.S. Supreme Court, the D.C. Circuit, the Federal Circuit, and the U.S. District Court for the District of Columbia.

Second, there are several reasons federal judges need to transact official business outside of their regular courthouse. 28 U.S.C. §§ 291 and 292 authorize a broad variety of temporary reassignments of circuit and district judges, both horizontally (i.e., to other circuits or districts) and vertically, so that a district judge can hear appeals and a circuit judge can try cases. 

Many federal judges serve on administrative panels like the judicial council for their circuit or the [[Judicial Conference of the United States]]. Some of the larger circuit courts like the Ninth Circuit hold regular sessions at multiple locations, and randomly select three-judge panels to hear appeals from all sitting circuit judges regardless of duty station.  Videoconferencing is sometimes now used to reduce the burden of frequent travel on circuit judges.
