Obligations of States in Undelimited Maritime Areas

Event Details

Time: 11.00-15.30

Venue: British Institute of International and Comparative Law, Charles Clore House, 17 Russell Square, London WC1B 5JP

Consisting of two panels featuring experts in Law of the Sea and members of the BIICL research project on the obligations of States in undelimited maritime areas, this event will analyse and discuss the obligations of States in regard to undelimited areas pending agreement on maritime boundary delimitation. In particular, the event will focus on the obligations of States under Articles 74(3) and 83(3) of UNCLOS to refrain from activities that could jeopardise or hamper the reaching of a final agreement on maritime delimitation.

The panels will present the findings of the BIICL research team and the implications of the research in practice. This will include a discussion of the impact of the decision of the ITLOS Special Chamber on provisional measures in the Dispute Concerning Delimitation of the Maritime Boundary between Ghana and Côte d'Ivoire in the Atlantic Ocean as well as relevant aspects of the Award on the Merits of the Annex VII Arbitral Tribunal in The Republic of Philippines v The People's Republic of China case (released 12 July 2016).

The event will be of interest to international law practitioners, government officials, offshore oil and gas industry specialists and academics. Copies of the BIICL publication "Report on the Obligations of States under Articles 74(3) and 83(3) of UNCLOS in respect of Undelimited Maritime Areas" will be distributed at the event.
