The Royal Arms as shown above may only be used by the Queen herself. They also appear in court rooms, since the monarch is the fount of justice in the UK and the law Court is part of the Court of the monarch (hence its name). Judges are officially representatives of the crown, demonstrated by the Queen's Coat of Arms which sits behind the judge on the wall of every court in the land.
