There are various levels of judiciary in England and Wales—different types of courts have different styles of judges. They also form a strict hierarchy of importance, in line with the order of the courts in which they sit, so that judges of the Court of Appeal of England and Wales are generally given more weight than district judges sitting in county courts and magistrates' courts.
