In an email interview, John E. Noyes, a professor of international law and the law of the sea at California Western School of Law, explained the significance of the move and how international tribunals for maritime disputes generally operate.
WPR: What are the steps for seeking arbitration under the United Nations Convention on the Law of the Sea (UNCLOS), and what is the scope of the disputes that can be settled under it?
John Noyes: Under UNCLOS, which has been accepted by 165 parties, countries involved in a dispute must first try to resolve it informally. If negotiation fails, the disputing parties may have recourse to arbitration. To begin the arbitration, an applicant country prepares a legal claim, sends it to the respondent country along with a notice of arbitration and names one member of the five-member arbitral tribunal. The respondent then has 30 days to name a second member of the tribunal, and the two disputants have another 60 days to agree on the remaining three members. If the respondent fails to name an arbitrator, or if there is no agreement on other tribunal members, the tribunal will still be constituted, but in that case the president of the International Tribunal for the Law of the Sea (ITLOS) selects the remaining arbitrators.
Once constituted, the arbitral tribunal must determine whether it has jurisdiction, that is, authority to decide the merits of the case. A tribunal has jurisdiction over disputes concerning interpretation or application of UNCLOS, with the exception of certain fishing and marine scientific research disputes. Countries may also refuse jurisdiction in cases concerning other specified sensitive matters, such as maritime boundaries and military activities. China, for example, declared in 2006 that it does not accept ITLOS jurisdiction with respect to those matters. In the Philippines’ recent case against China, the arbitral tribunal will dismiss for lack of jurisdiction if it determines that the case concerns maritime boundary delimitation or sovereignty over land. But the Philippines contends the case is among other things about China’s interference with navigational rights and whether certain features are “rocks” or “low-tide elevations” (rather than “islands,” which have extensive maritime zones); if the tribunal accepts the Philippines’ characterization, the tribunal would conclude that it has jurisdiction.
If an arbitral tribunal has jurisdiction, it will proceed to render a legally binding decision on the merits. This process may take several years.
WPR: What mechanisms are in place to enforce rulings made under UNCLOS arbitration or the ITLOS?
Noyes: UNCLOS for the most part does not provide enforcement mechanisms for arbitral or ITLOS decisions.
