This chapter assesses applications for provisional measures of protection under the 1982 United Nations Convention on the Law of the Sea (UNCLOS). At the Third UN Conference on the Law of the Sea, the need for courts or tribunals having jurisdiction under UNCLOS to have the power to prescribe provisional measures was beyond dispute although there was considerable debate concerning the details of the regime associated with such measures. The finally adopted Article 290 of UNCLOS, under the heading ‘Provisional measures’, represents the best possible compromise. Provisional measures are divided into provisional measures prescribed by the International Tribunal for the Law of the Sea (ITLOS) under Article 290(1) pending ITLOS’ judgment on the merits of the dispute, on the one hand, and provisional measures prescribed by ITLOS under Article 290(5) pending the constitution of an arbitral tribunal to which a dispute is being submitted, on the other hand. The request for the prescription of provisional measures shall be in writing and specify the measures requested, the reasons therefor, and the possible consequences, if the request is not granted, for the preservation of the respective rights of the parties or for the prevention of serious harm to the marine environment.
