Law plays an essential role in the establishment and operation of various international organizations because they are legal entities created by law (treaties concluded among States). In the past, the legal analyses of the structure and activities of international organizations have concentrated on studies of the provisions of the constitutive documents and of the resolutions, rules, decisions, etc., adopted by international organizations.
Today, the relationship between law and international organizations is more complex and a mere analysis of the provisions of documents establishing the organizations and of documents created by the organizations is neither sufficient nor comlegal plete.
First of all, international law is not the only legal system which has a direct relevance to the structure and operation of international organizations. The municipal law of states and the proper law of international organizations are also important systems affecting international organizations.
Secondly, the relationship between international organizations and a legal system is not one-way but two-way. One is the relationship where a legal system affects international organizations and the other is that where international organizations affect the legal system.
