Delegated legislationFrom Wikipedia, the free encyclopediaDelegated legislation(also referred to assecondary legislationorsubordinate legislation) islawmade by an executive authority under powers given to them byprimary legislationin order to implement and administer the requirements of that primary legislation. It is law made by a person or body other than thelegislaturebut with the legislature's authority...Delegated (or secondary) legislation is law made by ministers under powers given to them by parliamentary acts (primary legislation) in order to implement and administer the requirements of the acts. It has equal effect in law although ministers can be challenged in the courts on the grounds that specific pieces of delegated legislation are not properly based on powers given by acts. In the United Kingdom, delegated legislation, typically, is made through the force of statutory instruments in the form of ministerial regulations, orders in council, and codes of practice. The amount and scope of delegated legislation has grown as a result of the increasing pressure on parliamentary time. Advocates suggest that it represents an efficient way of relieving Parliament, that much of its subject-matter is uncontroversial, and that Parliament voluntarily gave up power in such irksome business. Critics object to the growing legislative autonomy of the executive from Parliament, and point out that deeply controversial matters, such as immigration rules, have been treated as delegated legislation. Increasing political concern was reflected in the House of Lords' successful defeat in February 2000 of an affirmative instrument by which government sought to deny candidates a free mailshot in the 2000 London Mayor election. Devolution to Northern Ireland (1998) and Scotland (1999) means that the assembly and parliament respectively make their own arrangements for primary and delegated legislation. The creation of the National Assembly for Wales 1999 established an elected institution that is unique in being solely responsible for the creation, scrutiny, and implementation of delegated legislation from primary legislation still drawn up by the UK Parliament.Jonathan Bradb..
