The paper begins by explaining the system of administrative law and judicial oversight of individual acts of public bodies, which are considered essential in any legal system focused on upholding the rule of law and protecting the rights of citizens and other legal entities. Expropriation, like other administrative acts issued by public bodies, often has a profound and immediate impact on the legal status of individuals, necessitating the establishment of effective mechanisms for ensuring the legality of such acts. This paper is based on an analysis of administrative judicial control over expropriation proceedings in the Republic of Croatia, with an emphasis on reviewing the Expropriation and Compensation Act and relevant court decisions that shape the practice of administrative courts. Through case studies, specific examples of judicial intervention in expropriation proceedings are presented, while a comparison with the practices of other countries evaluates the efficiency and fairness of the Croatian system. The paper examines the control mechanisms of administrative courts, taking into account their complexity and comprehensiveness through mechanisms that enable the control of constitutionality and legality of court decisions, as well as other control mechanisms. The first set of control mechanisms primarily arises from the basic law governing administrative disputes, while the second set is archetypically related to organizational regulations. Although these sets of control mechanisms originate from different types of regulations, it is clear that they together form a complementary whole.
