This book examines the relationship between governments and international organizations under international law. After surveying the policing powers of international organizations under international law, it illustrates some normative aspects of law that distinguish regulation from enforcement via study of recent legal cases before international judicial bodies. According to Dimitris Liakopoulos's expert analysis, if the two provisions codify the same general rule, the peculiarities of the relationship between an international organization and individual governments mean that sanctions decline when measured against the hypothesis that the latter facilitate an organization's violation of its obligations to all. The book concludes with peculiarities in the enforcement of international law by international organizations.
