This chapter concludes that the individual is considered in the legal reasoning of the Court in the identified contexts to a minor extent and offers reflections on the reasons for this. It recapitulates reflections on formalism and stability that are key in maritime and territorial boundary disputes. It notes that the Court is correctly limited to the request of the parties and cannot innovate beyond their submissions. However, across all chapters it was observed that state litigants often raise concerns about individuals in their custody. It therefore challenges the Court’s judicial caution when faced with potentially developing international law in addressing state’s concerns. It argues that while the Court does not have a formal law-making function, it develops international law nonetheless through its interpretations and clarifications and should not hesitate to do so when clarification is sought by state litigants on matters relating to the affected individuals in such disputes.

This chapter begins with a brief overview of the UNCLOS dispute settlement system established under Part XV UNCLOS. It then provides a conceptual framework for understanding what is meant by ‘development of the law’ by international courts and tribunals in order to set the stage for an analysis of the development of the law of the sea in the subsequent chapters. The chapter suggests a working definition of the term ‘development of the law’ and explains the ways in which international courts and tribunals ‘develop the law’. In the course of doing so, the chapter also explores the role of legal reasoning in the assessment of the contribution of judicial decisions to the development of international law.
