In the existing legislative process, the Montenegrin judicature faces a series of questions imposed by the practice of arresting ships. Legislation tries to respond to them by innovating the current regulations, based on the 1977, i.e. 1998 Maritime and Inland Navigation Act (MINA), and by taking into consideration the achievements of foreign, similar jurisprudences and legislations, as well as of international conventions. The proposed solutions in the draft of the Maritime Navigation Act represent a certain change in legislative systematization of the legal institute of temporary measure of ships arrest.
