PDF Version: The South China Sea Award and the duty of “due regard” under the United Nations Law of the Sea Convention
Decision Commented On: Award on the Merits of the Annex VII Tribunal, In the Matter of the South China Sea Arbitration, The Republic of the Philippines v The People’s Republic of China, 12 July 2016
As recited in an earlier post by Nigel Bankes, the Annex VII Tribunal in the South China Sea Arbitration (SCSA) handed down its Award on the Merits in the dispute between the Philippines and China on 12 July 2016. The dispute between the parties involves China’s extensive maritime claims in the South China (many within the context of the so-called nine dash line), claims in relation to fishing activities by Chinese flagged vessels, as well as claims in relation to China’s dredging and construction activities associated with reclamation activities on a series of maritime features in the South China. The Tribunal ruled in favour of the Philippines on almost all issues in its 479 page unanimous and comprehensive decision.
This post examines the Tribunal’s interpretation of the duty of “due regard” under the United Nations Law of the Sea Convention (LOSC) Article 58(3) in the course of its consideration of Submission No. 9 by the Philippines. That submission requested that the Tribunal declare that “China has unlawfully failed to prevent its nationals and vessels from exploiting the living resources in the exclusive economic zone of the Philippines” (at para 717). The obligation of “due regard” is one of the key mechanisms adopted in the LOSC to balance the potentially competing interests of coastal states and other uses of the new maritime zone, the exclusive economic zone, recognized by LOSC.
