The problem of limiting public use of maritime demesne as a form of public domain is as inherent to the doctrine of public domain as it is to the need of preserving it's unique natural and social value. Maritime demesne cannot be subject to any property rights, but can be subject to private exploitation by way of concessions, which are similar to property rights and give rise to various questions concerning the conflicting models of maritime demesne use. Thus, the development of maritime demesne, specifically beaches, is followed since the early Austro-Hungarian legislation, over the period of social ownerhsip, up to the current Martime Demesne and Maritime Ports Act. The legal typology of beaches, acquired rights, and grant, protection, and termination of concessions are discussed. Current solutions, which gained signitificant public attention, are contrasted with earlier Martime Demesne and Martime Ports Bill of 2003. Contrary to popular opinion, this paper demonstrates that the new Martime Demesne and Maritime Ports Act od 2023. does not in fact deviate significantly from previous legislation but, in fact, generaly improves it although certain issues, like those concerning the lien capacity of concession rights on maritime demesne, remain open.
