On 27 December 2020, in accordance with Articles 5, 7, 8, 10, 13 and 14 of UNCLOS, Presidential Decree No. 107 applies closing lines to the listed bays (Article 2 and Table) and further straight baselines (Article 3 and Table) in the maritime area of the Ionian and the Ionian islands up to Cape Tainaro in the Peloponnese. According to the Greek Ministry of Foreign Affairs, an extension of the territorial sea will be forthcoming as the baselines are “a necessary step in the process for extending the country’s territorial waters in the above-mentioned area”.
While limited in application to the Ionian Sea, Article 1(3) of Presidential Decree No. 107 provides that “The Hellenic Republic reserves the right to exercise its respective rights in the other regions of its Territory, as they derive from the United Nations Convention on the Law of the Sea of 10 December 1982, which reflects customary international law”.
