The United States Court of Appeals for the District of Columbia Circuit (in case citations, D.C. Cir.) is one of the thirteen United States Courts of Appeals. It has the smallest geographical jurisdiction of any of the U.S. courts of appeals, and it covers only the U.S. District Court for the District of Columbia. It meets at the E. Barrett Prettyman United States Courthouse in Washington, DC.
The D.C. Circuit is often considered to be second only to the U.S. Supreme Court in status and prestige, and it is sometimes unofficially termed "the second highest court in the land". Because its jurisdiction covers the District of Columbia, it tends to be the main federal appellate court for issues of U.S. administrative law and constitutional law. Four of the nine current Supreme Court justices were previously judges on the D.C. Circuit: Chief Justice John Roberts and associate justices Clarence Thomas, Brett Kavanaugh, and Ketanji Brown Jackson. Past justices Ruth Bader Ginsburg, Antonin Scalia, Warren E. Burger, Fred M. Vinson, and Wiley Blount Rutledge also served on the D.C. Circuit before their appointments to the Supreme Court.
Because the D.C. Circuit does not represent any state, confirmation of nominees can be procedurally and practically easier than for nominees to the Courts of Appeals for the other geographical districts, as home-state senators have historically been able to hold up confirmation through the blue slip process.
