The author examines how ‘consent’, traditionally taken as a foundational element in international law, fares in the context of international organizations (hereafter IOs). The central argument is that IOs, both as actors consenting to international law and as institutional spaces for other actors doing so, have changed the operation or even the nature of consent in international law as they have made the components of the act of consent disaggregate. The author argues that the IO’s expression of consent has become detached from the psychological or ‘intentional’ state that is presumed to be underlying in the legal subject. Where the organization appears as an institutional space for the consent of others, the object of consent in many instances is detached especially in substance from the normative effect created for the consent-giver.
