Abstract

This article discusses the ongoing transformation of international organizations law. It first provides an overview (an anatomy) of the paradigmatic theory concerning the law of international organizations: the theory of functionalism. Subsequently, it investigates how functionalism came about and how, from the 1960s onwards, its flaws increasingly became visible. The argument, in a nutshell, is that functionalism, as a theory concerned with relations between international organizations and their member states, has little or nothing to say about the effects of international organizations on third parties – non-member states, individuals and others. Moreover, it is often applied to entities that can hardly be deemed ‘functional’ in accordance with the theory. All of this is increasingly viewed as problematic and forces functionalism to adapt. Whether it can do so is questionable, though, since some of its problems are structural rather than contingent. Things are illustrated by the invocation of the United Nations’s possible responsibility for causing (or failing to prevent) the outbreak of cholera in Haiti.
