How to Do Things with International Law
This chapter presents an account of the international rule of law that reflects the particular dynamics of international politics, drawing on legal realism and practice theory in international relations (IR). On this reading, the international rule of law is a social practice that states and others engage in when they provide legal reasons and justifications for their actions. The goal may be either political legitimation for oneself or delegitimation of adversaries. This sort of use of international law both relies on and reinforces the idea that states should act lawfully rather than unlawfully. The priority of lawfulness is taken for granted. The chapter then outlines an approach which helps to make sense of international law's contribution to contemporary disputes and crises.
