Note, “Modern Trends in Legal Education,” 64 Columbia Law Bev. 710, 715 (1964) (“Older casebooks used legal concepts, for example, ‘mutual assent,’ ‘offer and acceptance,’ as the basis for classification. While modern casebooks employ this approach in acquainting students with the meanings and limits of technical legal concepts, they have increasingly recognized that such concepts are not uniformly applied in certain recurrent types of factual situations, and that to attempt to maintain a theoretical unity of legal doctrine in the face of the growing diversity is a distortion. Authors have sought to discover factual subgroupings of cases that are more significant than those denned by the traditional legal concepts.“—Citations omitted).

Law Q. 760 (1961), especially note 34, p. 768. As used here, it is descriptive of a broad and systematic hierarchy of those norms which relate to international organizations and which are appropriate for legal analysis and application. It closely parallels what Opsahl calls “the law of international institutions” and is meant to be somewhat more inclusive than what he calls “the constitutional law of international organizations.” Ibid,at 777.

It may be that the United Nations is sometimes not in a position to undertake action which would be useful for the maintenance of international peace and security or for one or another of the purposes indicated in Article I of the Charter, but that is the way in which the Organization was conceived and brought into being.“).

The phrase “domestic jurisdiction” used in Art. 2(7) referring to the jurisdictional competence of the U.N. has not yet been the subject of a direct Court inquiry, but the heated debate over its meaning and the propriety of a Court determination of that meaning indicates that if it does come before the Court, the Court will be forced to reassess its rôle in rendering binding one of several equally logical meanings.
