I was replying to Civenttone's comment about old U.S town laws.
Common Law is actually still laid down by Judges and Courts, and refers now to the Civil Law. Any break of this can only result in compensation. For example, Common Law sets duties of care in the case of Health and Safety at Work.
European Law and Statute Law are laid down by European parliament and U.K parliament respectively (Statute has to be enacted by the Queen). These overrule all Common Law and are used in Criminal Law where fines and criminal convictions can be handed down.
Sources of U.K law are Common, European and Statute (Or Parliament) Law. It's not a history lesson; it's basic law.
