Arbitral Tribunal has no jurisdiction to deal with the case of the Philippines against China over claims in South China Sea

The Arbitral Tribunal of the United Nations constituted under Annex VII of the 1982 UN Convention on the Law of the Sea, presided by Thomas Mensah, international maritime and environmental law advisor, is on its way to deal with the case brought about by the Philippines government against China. As a general principle, if one of the parties to the dispute does not appear before the tribunal - before making its award - the tribunal must first satisfy itself that it has jurisdiction over the dispute.

This finding of the jurisdictional question can only be based on the provisions of UNCLOS. So when China has refused to accept the jurisdiction of the tribunal according to relevant provisions of UNCLOS, how will it decide its jurisdiction over this case?

The basic reason why the Philippines has resorted to the Arbitral Tribunal is Article 287(3) of UNCLOS, which reads: "A State Party, which is a party to a dispute not covered by a declaration in force, shall be deemed to have accepted arbitration in accordance with Annex VII." In principle, Article 287(3) is based on and limited by Article 286 of UNCLOS, which says: "Application of procedures under this section: Subject to section 3, any dispute concerning the interpretation or application of this Convention shall, where no settlement has been reached by recourse to section 1, be submitted at the request of any party to the dispute to the court or tribunal having jurisdiction under this section."

On the jurisdiction question, the Arbitral Tribunal will have to decide whether or not this case is "a dispute not covered by a declaration in force". In other words, it has jurisdiction over a question that is a dispute in the legal sense and the dispute is "a dispute not covered by a declaration in force". But China made a declaration under Article 298 on Aug 25, 2006, which says the Chinese government "does not accept any of the procedures provided for in Section 2 of Part XV of the Convention with respect to all the categories of disputes referred to in paragraph 1 (a) (b) and (c) of Article 298 of the Convention".

Therefore, none of the categories of disputes referred to in the said paragraphs of Article 298 of the Convention, including those concerning maritime delimitation, can be decided by any international tribunal without the consent of the parties concerned. The reason for these exceptions is not difficult to understand.

The compulsory procedures in the UNCLOS regime are applicable only to "any dispute concerning the interpretation or application of this Convention" (Article 286). And in cases in which there is no meaning to interpret and no rule to apply, such as articles 15, 74 and 83 of UNCLOS, there is no possibility of any international tribunal to adequately exercise its judicial function.

The relief sought by the Philippines, which requests the Arbitral Tribunal to declare "that China's rights in regard to maritime areas in the South China Sea, like the rights of the Philippines, are those that are established by UNCLOS" is obviously not a dispute in the legal sense, because there is no conflict of legal views between the parties in this regard.
