This document discusses the forms of judicial control over delegated legislation in India. It outlines two main forms - substantive ultra vires and procedural ultra vires. Substantive ultra vires occurs when delegated legislation goes beyond what is authorized in the parent act. Procedural ultra vires happens when procedural requirements like publication or consultation are not followed. The document provides examples of when courts have struck down delegated legislation on these grounds, such as when the parent act or delegated legislation is unconstitutional or inconsistent with the parent act or general law. It also discusses requirements around publication and consultation of delegated legislation.
