what is a circuit judge

A circuit judge is a type of judge in various jurisdictions. In England and Wales, circuit judges are judges who sit in the Crown Court, the County Court, and some specialized sub-divisions of the High Court of Justice, such as the Technology and Construction Court. They are styled His or Her Honour Judge X and are referred to as His or Her Honour. They are sometimes referred to as "purple judges" on account of their purple color dress robes. Circuit judges rank below High Court judges but above district judges. They may be appointed to sit as deputy High Court judges, and some of the more senior circuit judges are eligible to sit in the Criminal Division of the Court of Appeal). In the United States, circuit judges are judges who sit on any of the United States courts of appeals, known as circuit courts. They usually sit in a panel of three judges and determine whether or not the law was applied correctly in the district court, also known as trial court, as well as appeals from decisions of federal administrative agencies and some original proceedings filed directly with the courts of appeals.
