The term concession has been known since the Roman times, when the public authorities were leasing the state revenue or the right to perform the works. The concession law was introduced into the Croatian legal system in 1990, and the last editing of the Concession Law was performed in 2017. The meaning of the word concession is a license or approval from the public authorities given to a lawful subject to use certain goods, carry out the works or give certain services. The concessions are always developed between two sides: the grantor and the concessionaire. Prior to granting of the concession it is necessary to carry out the preparatory actions, which include: the naming of the expert committee, the development of a justification for granting a concession or a concession analysis, the assessment of concession value and the drafting up the bidding documents. In order to build a concession relationship it necessary to conclude a concession contract defining the rights and obligations of the grantor and the concessionaire. Regarding the concessions in the public sector activities, a concession can be given for granting the right to economically use the public or other goods, public works and public services.
