Delegated legislation or secondary legislation in the United Kingdom is law that is not enacted by a legislative assembly such as the UK Parliament, but made by a government minister, a delegated person or an authorised body under powers given to them by an Act of Parliament. Statutory Instruments are the most frequently used type of secondary legislation, with approximately 3,500 made each year, although only about 1,000 need to be considered by Parliament. They usually have either rule, order or regulation in their title.
