Starting on March 1, more than 1,000 employees of the federal judiciary will be subject to a policy that prohibits them from partisan political activity, including campaign contributions.

Judges and court employees have lived under similar rules for decades, but the new policy extends the restrictions to those who work at the Administrative Office of the U.S. Courts and the Federal Judicial Center, both based at the Thurgood Marshall Federal Judiciary Building in Washington, D.C.
