Third Parties in International Law examines the impact upon the traditional bilateral framework for the regulation of international affairs that has been made by the accommodation of third party claims and interests. There is a detailed analysis of the position of third parties (defined both as individual actors within the international arena, and the broader international community) in three areas of international law: treaties; international procedure (adjudication and arbitration) and the illegal use of force, in order to determine the position of third parties in international law generally. From this third party perspective there is discussion of the modern processes for the making and application of international law.
