This document outlines the criminal court appeals system in the UK. It begins with criminal cases starting in the Magistrates Court, which can be appealed to the Crown Court. Defendants and prosecutors can further appeal to the Court of Appeal on points of law or unduly lenient/harsh sentences. The highest court is the House of Lords, which will hear appeals on important points of law or those of public importance, if permission is granted. The document provides details on the jurisdiction and appeal options at each level of the criminal courts system.
