The issue of concessions on maritime property is governed by two key laws in the Republic of Croatia: the Law on Concessions, as lex generalis, which establishes the general legal regime of concessions, and the Law on Maritime Property and Seaports, as lex specialis. The detailed procedure for granting concessions on maritime property is regulated by the Regulation on the procedure for granting concessions on maritime property, which is a secondary legal act. The term „concession” has its linguistic roots in the Latin word „concessio”, which generally means approval, permission, permit or guarantee. In terms of content, a concession represents a special legal institute by which the public authority allows a certain subject, whether physical or legal, domestic or foreign, to use, exploit certain goods, perform certain works or carry out a certain activity. The concession establishes a bilateral legal relationship between the grantor of the concession (grantor) and the recipient of the concession (concessionaire), from which certain rights and obligations arise for both parties. The procedure for awarding concessions on maritime property involves the adoption of two acts, different in their legal nature. The first act is the concession decision, while the second act is the concession contract concluded on the basis of the concession decision. Depending on the purpose of granting the concession, the procedure may differ for economic or special use. In order to obtain a concession on maritime property, it is necessary to pay an annual fee, which is defined in the concession decision. The amount of compensation is determined based on consideration of economic justification, degree of endangerment of nature and the human environment, and protection of the interests and security of the Republic of Croatia.
