Advancement of the Duty to Cooperate in Marine Environmental Protection in the Jurisprudence of ITLOS

The UN Convention on the Law of the Sea sets forth an unprecedented regime for marine environmental protection that compels parties to cooperate and includes mandatory dispute settlement procedures with binding decisions. Although the Convention does not contain a specific article stipulating a general duty to cooperate, cooperation permeates the logic of the document. The International Tribunal for the Law of the Sea (ITLOS) has recognised the importance of cooperation to marine protection and preservation in several cases. It could be suggested that the States Parties have a positive obligation to cooperate and a need to implement a range of actions to this end. ITLOS has consistently interpreted the duty to cooperate as comprising specific obligations: to consult, to exchange information, to monitor and assess relevant activities, to develop measures to prevent pollution or other environmental harm; which offers both the basis for the implementation of the duty to cooperate and the criteria for determining compliance.
