The Travaux Préparatoires of the Vienna Convention on the Law of Treaties

Published online by Cambridge University Press:  28 March 2017

Extract

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?

The United States proposal (A/Conf.39/C.1/L.156, April 10, 1968, Vienna Conference, Official Records, III, p. 149) reads as follows: “Amend article 27 to read as follows: “A treaty shall be interpreted in good faith in order to determine the meaning to be given to its terms in the light of all relevant factors, including in particular: (a) the context of the treaty; (b) its objects and purposes; (c) any agreement between the parties regarding the interpretationof the treaty; (d) any instrument made by one or more parties in connexion with the conclusion of the treaty and accepted by the other parties as an instrument related to the treaty; (e) any subsequent practice in the application of the treaty which establishes the commonunderstanding of the meaning of the terms as between the parties generally; (f) the preparatory work of the treaty; (g) the circumstances of its conclusion; (h) any relevant rules of international law applicable in the relations between the parties; (i) thespecial meaning tobe given to a term if the parties intended such term to have a special meaning.“ “Delete article 28.“

16 The text of the United States proposal (above, note 12) appears to have been based verbatim (except for the addition of sub-paragraphs (d), (h), and (i)) on the proposal made by the writer to the International Law Commission at its 870th meeting on June 15, 1966. In introducing the proposal, the writer explicitly stated that it was “to the text that the interpreter should first look rather than to the intention of the parties, which was a subjective element distinct from the text itself'; adding: “If his suggestion were adopted, the text would retain its basic importance as the authentic expression of the intentions of the parties, but nothing that might throw light on the meaning of its terms would be excluded… .” 1966 I.L.C.
