'One of the First Matters to be Addressed but Distinct' or 'Distinct but Inseparable'? The Distinction Between Maritime Entitlement and Sea Boundary Delimitation in the Philippines v. China Arbitration

The distinction between disputes of sea boundary delimitation and disputes over the existence of maritime entitlements was one key element of the legal argument that the Philippines brought forward against China in the Philippines v. China Arbitration. On the one hand, the distinction between delimitation and entitlement allowed the Tribunal to establish its jurisdiction on several Philippine submissions despite the jurisdictional exclusions of China's declaration under Article 298(1)(a)(i) of the Law of the Sea Convention. On the other hand, the Tribunal's finding about the lack of China's entitlements has important consequences. China and a number of lawyers objected to the jurisdictional separability of entitlement and delimitation. The aim of this paper is to discuss the question of whether a tribunal can establish jurisdiction on the existence of maritime entitlements in a context where jurisdiction on boundary delimitation is excluded and where a determination of entitlements has consequences for boundary delimitation.
