"It is clearly established by earlier cases, in particular R v St Albans Crown Court ex parte Cinnamond and R v Croydon Crown Court ex parte Miller, that judicial review did not offer a backdoor means of appeal against the sentences imposed by the Crown Court and appeals from justices. It was nevertheless recognised by those authorities that there came a point at which a penalty was so far outside the reasonable range of penalties as to be indicative of a manifest error of law."
