Adopted in 1921, in order to determine the basic principles of state and social organization, the Vidovdan Constitution contained certain provisions that are still acceptable today 100 years later. Moreover, the Vidovdan Constitution represents one of the most important moments in the creation of the administrative judiciary of the states that later emerged in the territory of the Kingdom. Namely, the literature states that the organization of the administrative judiciary, provided by the Constitution, leads to the most significant period in the development of the administrative judiciary (in Serbia) from its founding in 1869 until the Second World War. In this regard, as one of the most important aspects, authors emphasize the introduction of a two-tier administrative judiciary, with significant guarantees of professionalism in the selection of judges. Having in mind its significance in the history of the administrative judiciary, the authors will analyze the basic constitutional norms regarding the legal nature and organization of the administrative judiciary. Also, the research will include the issue of the position of judges of the administrative court and members of the State Council. In addition to the constitutional provisions, paper gives mentions to relevant provisions of the Law on the State Council and Administrative Courts, as well as the Decree on the State Council and Administrative Courts adopted shortly after the Vidovdan Constitution.openAccesshttps://creativecommons.org/licenses/by-nc-nd/4.0/Vidovdan Constitutionadministrative judiciaryState Counciladministrative courtsarticle10.46793/zbVU21.233J
