Decisions of International Institutions

Decisions of the International Institutions may lead to the formation of rules of international law in a numbers of different ways as follow:

1- They may represent intermediate or final steps in the evolution of customary rules particularly those governing the constitutional of these institutions.
2- A resolution of the organ of an international institution which validly formulates principles or regulations for the internal working of the institutions may have full legal effect as laying down rules which are binding on the members and organs of the institution.
3- Inasmuch as an organ of an international institution has inherent power,in doubtful cases not precisely covered by its Constitution to determine the limits of its own competence,such decisions by it on questions of its jurisdiction may have a law-making effect.
4- Sometimes,organs of international institutions are authorised to give binding determinations concerning the interpretation of their constituent instruments,for example, the Executive Directors and the the Board of Governors of the International Monetary Fund have such power under article XVII of the Articles of Agrreement of the Fund of 22 july1944.these interpretative decisions will form part of the law of the international institution in question.
5- Some organs of international institutions are empowered to give general decisions or directives of quasi-legislative effect,binding on all the members to whom they are addressed.for example,as are the Council and Commission of the European Economic Community ( Common Market ) under article 189 of the Treaty of Rome of 25 March 1957 establishing the Community.
6-A special case is that of the determinations or opinions of Committees of Jurists,specifically instructed by the organ of an international institution to investigate a legal problem.these necessarily bear some weight and authority.
