4 Advisory Opinions by ITLOS
This chapter focuses on advisory opinions by the International Tribunal for the Law of the Sea (ITLOS). Like the International Court of Justice, ITLOS may render and has rendered advisory opinions on legal questions within its areas of competence. The 1982 United Nations Convention on the Law of the Sea (UNCLOS) expressly provides for the advisory jurisdiction of the Seabed Disputes Chamber of ITLOS, but not the full bench of ITLOS itself. According to Article 191 of UNCLOS, the Seabed Disputes Chamber shall give advisory opinions at the request of the Assembly or the Council of the International Seabed Authority on legal questions arising within the scope of their activities, and such opinions shall be given as a matter of urgency. The full bench of ITLOS has held that the substantive legal basis of the full-bench ITLOS’ advisory jurisdiction is Article 21 of its Statute stipulating that ITLOS’ jurisdiction comprises all disputes and all applications submitted to it in accordance with UNCLOS and all matters specifically provided for in any other agreement which confers jurisdiction on ITLOS. The ITLOS Rules elaborate the procedure in this respect.
