An Introduction to Public International Law

This chapter begins by elaborating on the concept of a dispute, before providing a historical perspective on the evolution of the requirement to settle disputes peacefully. The chapter then explores diplomatic as well as legal methods of dispute settlement. Diplomatic forms of dispute settlement (also known as political or non-legal forms of dispute settlement) include negotiation, mediation, inquiry, and conciliation. Legal forms of dispute settlement include arbitration and adjudication. Resort by states to dispute settlement procedures, and in particular legal methods of dispute settlement, has grown exponentially in the last decades. Since the 1990s, the International Court of Justice has had an increasingly active docket of cases, and, in addition, the Permanent Court of Arbitration has undergone a sort of renaissance. The focus of this chapter will be on the settlement of inter-state disputes, as opposed to disputes between states and non-state actors or between non-state actors.
