Self-judgment in international law: Between judicialization and pushback

Abstract The legally binding unilateral application of norms holds potential for abuse. Nonetheless, self-judgment is alive and kicking. Self-judgment language commonly features in treaties and states frequently invoke their authority to ‘self-judge’ sensitive issues, such as matters related to national security, before international judicial bodies. In many of these cases, the controversy whether a norm has a self-judgment quality or not has been decisive for the outcome of the dispute. Yet, the meaning and consequences of self-judgment remain contested. This article develops self-judgment as the authoritative application of international legal norms by states. It posits that steps towards the judicialization of self-judgment by judicial bodies have given rise to state efforts to preserve unfettered discretion. Notably, states have responded to attempts by judicial bodies to gain authority over the application of self-judgment by drafting provisions more explicitly. This dynamic continues to make self-judgment a site of judicialization and pushback. The only way to understand the meaning, limitations and development of self-judgment is by studying this process. Doing so conceptually refines self-judgment and allows for more meaningful references to the notion in practice.
