Judicial supervision begins to develop throughout history and becomes one of the main instruments for controlling the legality of the work of the administration. The courts were chosen to perform this function because of their expertise, but also because of their independence from the work of the administration. The judiciary still performs this function today. It is an effective form of legal supervision of the work of the administration in order to protect human rights and fundamental freedoms in a certain respect. Through this paper, I will show how judicial supervision of administration has developed in the Republic of Croatia since the creation of Austria-Hungary itself, and ending with the reform of the administrative dispute, which entered into force in 2012. Its development was marked by different organizational forms and solutions through which this supervision was carried out. Throughout history, at certain moments, Croatia was fragmented into several territorial units, thus weakening its political position. We can note that in such a development, the Croatian legal system accepted only those normative and organizational solutions from previous systems. Such decisions were used as a blueprint for the creation of a completely new system of judicial supervision of the administration. The development of such systems was dynamic, but the main goal was to create a stable management control system. The Republic of Croatia took over the Law on Administrative Disputes from the SFRY, but such a law was full of shortcomings, but the main one was incompatibility with the acquis of the European Union. This led to the reform of the administrative dispute in 2012 in order to harmonize the system of Croatian judicial supervision of the administration with European legislation. After the implementation of this reform, we can talk about the original Croatian system of judicial supervision of the administration. Over a period of time, it will be clear whether anything needs to be changed in the system in order to respond to the demands that come to it as functionally and efficiently as possible.
