Why isn there the Royal Coat of Arms in every court?
Justices of the Supreme Court administer Justice in the name of HM The Queen. A version of the Royal Coat of Arms is installed above the entrance to the building and an historic version is also on the ceiling of the Library. As a United Kingdom Court (hearing civil appeal cases from all over the United Kingdom and all criminal cases in England and Wales and Northern Ireland), the decision not to use the Royal Coat of Arms in the courtrooms took account of the provisions of the Justice (Northern Ireland) Act 2002 and the fact that different versions of the Coats of Arms are used in different parts of the UK. The decision also took account of the fact that the Judicial Committee of the Privy Council also sits in the building, and it is the final Court of Appeal for some countries which are Republics.
