There is no official codification of English law. Each act of Parliament is referred to by its original title and date of enactment, i.e. the Human Reproductive Cloning Act of 2001. Prior to 1963, acts were referred to by regnal year, or year of the monarch's reign, i.e. 3 Edw. 7, c. 36 would denote the 36th act passed in the 3rd year of the reign of Edward VII. A table of regnal years of English sovereigns can be found in Sweet and Maxwell's Guide to Law Reports and Statutes.
