In 1947 the Judicial Constitution Act and the Administrative Court Act were repealed. This marked a new beginning for the new court system. It has been more than 50 years since this happened in which time the system of judicial review of administrative action has developed. However, the contemporary situation raises for us many problems for which we need urgent reform. I would like to reflect upon the merits and demerits of the court's role in administrative cases by means of reference to major Supreme Court cases.
