Book excerpt: The United Nations Convention on the Law of the Sea is one of the most important constitutive instruments in international law. Not only does this treaty regulate the uses of the world's largest resource, but it also contains a mandatory dispute settlement system - an unusual phenomenon in international law. While some scholars have lauded this development as a significant achievement, others have been highly sceptical of its comprehensiveness and effectiveness. This book explores whether a compulsory dispute settlement mechanism is necessary for the regulation of the oceans under the Convention. The requisite role of dispute settlement in the Convention is determined through an assessment of its relationship to the substantive provisions. Klein firstly describes the dispute settlement procedure in the Convention. She then takes each of the issue areas subject to limitations or exceptions to compulsory procedures entailing binding decisions, and analyses the interrelationship between the substantive and procedural rules.
