The aim of this paper is to show corruption, that is, a social phenomenon that threatens the fundamental values of society and the state. At the same time, we want to show how its consequences affect the orderly functioning of state institutions and state power. Therefore, an example from practice analyzes corruption through criminal acts, and the introductory part provides an overview of its definition, methods of measurement, and possible consequences. The paper describes chronologically the course of events and the factual situation of the case related to corruption, and which criminal acts were charged to the defendants. The two most represented corrupt criminal acts from the Fimi Media case are explained in detail, and what conditions had to be met for the prosecution of these criminal acts, as well as providing an insight into how and why the court ruled against the defendants in the mentioned case. The paper also analyzes the representation of these criminal acts in the last five years in relation to the categories of perpetrators, reports, accusations and convictions of adult perpetrators of criminal acts. GRECO's recommendations for Croatia and the measures taken by Croatia to implement them are also analyzed. At the same time, the recommendations from the Report of the Ombudsman and the goals and areas of action for the prevention of corruption, which are defined as priorities in the Strategy for the Prevention of Corruption and the Action Plan, are presented.
