Public procurement is certainly an important segment of the economy of every country through which considerable public money is spent on the procurement of goods, works and services necessary for regular business operations and the performance of public and sectoral activities. Therefore, it is important that every part of the public procurement procedure is regulated in detail in order to carry out these procedures transparently and efficiently with the maximum possible prevention of corrupt and other illegal actions. Through public procurement procedures, the obligees of the Law on Public Procurement procure various goods, services and/or works in their daily operations, for which they use public money. Year after year, the amount of public funds used in public procurement grows, which is why greedy individuals who participate in public procurement procedures on behalf of public clients, engage in various illegal actions, trying to obtain financial or other benefits for themselves. Therefore, it is clear that the legislative-legal and institutional framework of public procurement should protect these public funds and honest participants in public procurement procedures. As the fundamental goals of public procurement are: the achievement of market competition, the efficiency of the procedure and the suppression of corruption, transparency and adequate legal regulation are of essential importance for ensuring fair and open procurement procedures and for their effectiveness and for the prevention of corruption and other criminal and misdemeanor acts. Through the consistent application of the Law on Public Procurement, the Criminal Law and the Law on the Protection of Market Competition and the effective work of the state administration body responsible for public procurement policy in the Republic of Croatia and the effective work of the State Commission for the Control of Public Procurement Procedures, it is possible to achieve the fundamental goals of public procurement. A clear and unequivocal legislative framework for public procurement and its efficient institutional framework are a prerequisite for quality legal protection in public procurement procedures, and thus greater legal security for all participants in public procurement.
