The court system is headed by the Senior Courts of England and Wales, consisting of the Court of Appeal, the High Court of Justice for civil cases, and the Crown Court for criminal cases. The Supreme Court of the United Kingdom is the highest court for criminal and civil cases in England and Wales. It was created in 2009 after constitutional changes, taking over the judicial functions of the House of Lords. A decision of the Supreme Court is binding on every other court in the hierarchy, which must follow its directions.
