The Lord Chief Justice of England and Wales is the head of the judiciary and President of the Courts of England and Wales. Historically, he was the second-highest judge of the Courts of England and Wales, after the Lord Chancellor, but became the top judge as a result of the Constitutional Reform Act 2005, which removed the judicial functions from the office of Lord Chancellor, altered the duties of the Lord Chief Justice and changed the relationship between the two offices. The Lord Chief Justice is also President of the Criminal Division of the Court of Appeal.
