Administrative courts in the Republic of Croatia represent institutions that provide legal protection to citizens and legal entities in disputes with state and public bodies and make decisions on the legality of administrative acts and other procedures of public authorities. Administrative courts in the Republic of Croatia have been developing for many decades, starting from the period of the Austro-Hungarian Monarchy when some forms of administrative law and control were introduced, and after the creation of the Kingdom of Yugoslavia, some laws were introduced that regulated administrative disputes, but administrative courts were not were significantly developed. As time passed, administrative disputes in the former Yugoslavia, and later in the Republic of Croatia, were increasingly controlled and regulated through laws and regulations, the most important of which is the Administrative Disputes Act. Special changes are visible with the entry of the Republic of Croatia into the EU, when there was a need to adapt Croatian standards to European standards. It was then that some new institutes were introduced and better protection of the rights of citizens and legal entities in disputes against state and public bodies. Digitization has introduced more and more measures with the aim of speeding up procedures and increasing transparency, which was only further confirmed by the latest Law on Administrative Disputes, which entered into force on July 1, 2024.
