The field of public procurement is a vast and important legal field. In the procedures of public procurement, there is a case of the use of public finance because of which the procedure of exercising legal protection has to be regulated appropriately in these procedures. The current legal arrangements anticipate legal protection, first, in the pre-audit procedure which takes place at the client, then, in the audit procedure which takes place at the National Review Commission for Reviewing Public Procurement Procedures, and finally, in the court proceedings which take place in the district court at first instance. The entire procedure is substantially marked by the principle of quick pace and efficiency because the legislator strives for the accomplishment of undisturbed operation of state bodies by ensuring goods, services, and constructions necessary to perform the tasks of the public sector. On the other hand, we have to be careful in these procedures that this principle does not weaken the efficiency of exercising the legal protection of applicants of the review claims and that it does not violate their right to legal protection. In the master’s thesis titled Pre-audit and Audit Procedures in Public Procurement, the essential characteristics and the course of the entire procedure of legal protection are presented. In the thesis, I warned about the current issues from this field, presented the novelties brought by the law amendment of the Legal Protection in Public Procurement Procedures Act, and proposed some changes of the arrangements.
