The Coming of Age of International Organizations

Arguably, it is with this newly acquired constitutional identity that international organizations have come of age and can participate as mature legal actors in international affairs. At the same time, in today’s IOs elements of both the functional and institutional stages persist. Within this broader view, the project aims to look especially at the IO as a global actor and as a norm-creator.
