The Travaux Préparatoires of the Vienna Convention on the Law of Treaties
The fundamental importance of the codification of the law of treaties by the International Law Commission and the Vienna Conference will gain increasing recognition as the rules and principles embodied in the 1969 Vienna Convention on the Law of Treaties are applied in the practice of states and the jurisprudence of international tribunals. Inevitably the records of this great codification will be searched and researched, by scholars as well as by legal advisers, and for a variety of reasons: What is the function of a particular rule? What r61e was it designed to play in the relations of states and in the international legal community? What does it require in the way of performance or abstention? Is it a residual rule, binding upon states if no other solution is agreed on? Why was the rule given the particular formulation found in the Vienna Convention,and what alternative formulations were rejected? Since the entry into force of the Vienna Convention will be delayed until after thirty-five states have ratified or acceded to it (Article 84), what assessment of the general acceptability of a particular provision can be gained from a study of the drafting record or from the number of affirmative or negative votes or abstentions?
