There are three main types of delegated legislation: bylaws made by local councils, statutory instruments made by government departments, and Orders in Council made by the Privy Council. Parliament delegates some of its lawmaking power through enabling acts because it does not have time or expertise to pass all necessary laws itself. Delegated legislation is subject to general supervision through the enabling act and requirement for consultation, publication, and parliamentary and court oversight through judicial review. It allows laws to be made more quickly and flexibly by experts but is also criticized as being undemocratic with reduced transparency and scrutiny compared to laws passed by Parliament.
