Guyana / Suriname

Date of Award: 17 September 2007

Guyama and Suriname maritime boundaryIn 2004 Guyana initiated arbitral proceedings against Suriname relating to the dispute concerning the single maritime boundary between the two States. Pursuant to Articles 286 and 287, and Annex VII of the United Nations Convention on the Law of the Sea (UNCLOS), the Arbitral Tribunal was established to delimit the maritime boundary and to adjudge on the lawfulness of various acts committed by these states in the disputed area.

On 20 September 2007, the Award of the Tribunal was made public by the Permanent Court of Arbitration in The Hague. The Award established a single maritime boundary between Guyana and Suriname which differed from the boundaries claimed by each of the Parties in their pleadings. The boundary was primarily defined by means of the “median line”, whereas in case of delimitation of continental shelf and exclusive economic zone the Tribunal adopted the “unadjusted equidistance” method. Additionally, the Tribunal found that both Guyana and Suriname failed to make every effort to find provisional arrangements and of 'jeopardizing or hampering the reaching of a final agreement'.
