Application of Fundamental Criteria of the Reservation Right in Statutes of International Organizations with Emphasis on Vienna Convention on the Law of Treaties

Governments were the main players in international law for a long time and insisted on the integrity of international treaties and believed that changing every word of a bilateral or multilateral treaty would be only possible through collective agreement and consensus of all members. As a result of more cooperation and interaction in multilateral relations among governments، as well as establishment and quantitative and qualitative development of regional and international organizations، and also as a result of efforts made to encourage accession of more governments to international conventions، especially human rights conventions or statutes of international organizations، the issue of the right to reservation has been recognized by the community of international legal experts under specific conditions. In some cases، application of this right to statutes of international organizations is surrounded by ambiguities which constitute the main subject of the present study.
