The purpose of the Promotion of Administrative Justice Act, 2000, is to give effect to the constitutional right to administrative action that is lawful, reasonable and procedurally fair. The Act serves as a basis to promote efficient public administration and creates a framework for the valid execution of all administrative actions. The Act contains a number of definitions of the concept administrative action, all of which strongly suggest that administrative action entails much more than mere actions and means, in fact, a decision and an activity of an administrative nature. Since the Act is rather cumbersome in its definition of the concept administrative action, this article clarifies the different types of actions, explains when particular actions are regarded as administrative action, and describes when such actions take effect and when they may be altered.
