The role of international organizations on the world scene has assumed increasing significance. The world community has come to realize that only through the joint and coordinated action is possible for international organizations to confront threats and at the same time ensure friendship and cooperation among states. At the same time, the issue, on which conditions international organizations should incur international responsibility for violating international obligations acquires a growing importance. Unambiguous provisions in the international law of treaties are rare, precedent-setting decisions are few. The article examines the issues arising in the process of codification of norms of responsibility of international intergovernmental organizations and analyzes the current development in that area. The differences between the Draft articles on the responsibility of international organizations (2011) and the Draft articles on responsibility of states for internationally wrongful Acts (2001) have been investigated. It is indicated that it is necessary to adopt the Universal convention based on the Draft articles on the responsibility of international organizations which will be an important step in the development of the law of international responsibility and the strengthening of the international legal order.
