The Supreme Court is the highest court in the United Kingdom and hears appeals on arguable points of law of the greatest public importance, for the whole of the United Kingdom in civil cases, and for England, Wales and Northern Ireland in criminal cases. Additionally, it hears cases on devolution matters under the Scotland Act 1998, the Northern Ireland Act 1998 and the Government of Wales Act 2006. This jurisdiction was transferred to the Supreme Court from the Judicial Committee of the Privy Council. The Supreme Court sits in the former Middlesex Guildhall, on the western side of Parliament Square.
