Public International Law

All states have an obligation to settle disputes peacefully in accordance with arts 2(3) and 33 of the Charter of the United Nations (‘UN Charter’), and the purpose of this chapter is to provide an introduction to the methods for the settlement of international disputes. It begins with an overview of international dispute settlement, including a discussion of the concept of a ‘dispute’, and the distinction between political and legal disputes. It then traces the evolution of the obligation to settle disputes peacefully through its broad phases: the 1899 and 1907 Hague Conventions for the peaceful settlement of international disputes, and the creation of the Permanent Court of Arbitration; the Covenant of the League of Nations of 1919, and the creation of the Permanent Court of International Justice (‘PCIJ’); and the Kellogg–Briand Pact of 1928, and the UN Charter of 1945. The chapter then considers the various methods of international dispute settlement, beginning with the diplomatic methods (negotiation, fact-finding and inquiry, the use of ‘good offices’, mediation, and conciliation) before turning to the adjudicatory forms of dispute settlement.
