ABSTRACT
In the field of economics and technology, there is uncertainty as to the legal Psychological of emerging principles of international trade and economic assistance for the benefit of the developing countries which have not yet assumed conventional legal form. The practical international lawyer is supposed to be concerned not with the foundation of obligation but with the so-called "sources," formal and material. Even the International Court of Justice, which is governed expressly by Article 38 of its Statute as to the sources of law, has demonstrated time and again that in their deliberative process the judges have had to look to theory to evaluate practice. A useful distinction may be drawn between subjects that are normally within the exclusive competence of states and those which fall within the area of shared or inclusive interests. The acceptance of the authority of a group may also depend on its procedures and linguistic symbols.
