This Practice Note explains how to appeal to the UK’s Supreme Court (sometimes called the ‘UKSC’) in criminal matters. Appeal to the Supreme Court comes from the Court of Appeal (Criminal Division) or the High Court in a ‘criminal cause or matter’ where there is a point of law of general public importance in issue. The Practice Note includes the statutory basis of appeal to the Supreme Court, appeal from the High Court, appeal from the Court of Appeal (Criminal Division) and the procedure for appeal to the Supreme Court. The Practice Note also covers applying to the Supreme Court for permission to appeal and what to do when permission is not required, preparation of an appeal when permission is granted, the appeal hearing at the Supreme Court, time limits for appeal to the Supreme Court and orders made by the Supreme Court following the hearing.
