Declaration under Article 287 (December 2, 2015):
"In accordance with Article 287, paragraph 1, of the United Nations Convention on the Law of the Sea, the Republic of Bulgaria declares that it accepts the jurisdiction of the International Tribunal for the Law of the Sea for the settlement of disputes concerning the [interpretation] or application of the Convention."
Objections made on September 17, 1985:
"The People's Republic of Bulgaria is seriously concerned by the actions of a number of States which, upon signature or ratification of the United Nations Convention on the Law of the Sea, have made reservations conflicting with the Convention itself or have enacted national legislation which excludes or modifies the legal effect of the provisions of this Convention in their application to those States. Such actions contravene article 310 of the United Nations Convention on the Law of the Sea and are at variance with the norms of customary international law and with the explicit provision of article 18 of the Vienna Convention on the Law of Treaties.
Such a tendency undermines the purport and meaning of the Convention on the Law of the Sea, which establishes a universal and uniform regime for the use of the oceans and seas and their resources. In the note verbale of the Ministry for Foreign Affairs of the People's Republic of Bulgaria to the Embassy of the Philippines in Belgrade, [...] the Bulgarian Government has rejected as devoid of legal force the statement made by the Philippines upon signature, and confirmed upon ratification, of the Convention.
The People's Republic of Bulgaria will oppose in the future as well any attempts aimed at unilaterally modifying the legal regime, established by the United Nations Convention on the Law of the Sea."
