International Responsibility

The final consequence of the dual legal nature discussed in the book concerns the international responsibility of international organizations. In particular, this chapter describes how the absence of a common conceptualization affected the work of the International Law Commission, the International Law Institute, and the International Law Association. Afterwards, the chapter focuses on the dual attribution of conduct to an international organization and to its member states. It contends that dual attribution is extremely important in practice and it reviews the cases in which it was at issue. After providing a set of principles on how to apply the dual attribution, it distinguishes between three sets of circumstances: dual attribution via institutional links, dual attribution via factual links, and exclusion of dual attribution when the conduct is attributable to only the organization or its member states. Finally, it discusses the effects of dual attribution in terms of joint responsibility.
