Nearly three decades ago I published in this JOURNAL an article in which I tried to prove that even in international law there exist rules having the character of jus cogens; i.e., norms with which treaties must not conflict. Since my eminent colleague in the International Law Commission, Ambassador Tabibi, mentioned in a meeting of this Commission that the view expressed in my article “foreshadowed the solution” embodied in Article 37 of the Commission’s draft Convention on the Law of Treaties concerning the problem of jus cogens in international law, I feel obliged to defend this draft against the criticism directed against it by the eminent English lawyer, Professor Georg Schwarzenberger.

See, further, on this topic before the second world war, von der Heydte, “Die Erscheinungsformen des zwischenstaatlichen Eechts: jus cogens und jus dispositivum im Völkerrecht,” in 16 Zeitschrift für Völkerrecht 461 et seq. (1932); and Jurt, Zwingendes Völkerrecht (1933).
2 See 1 I.L.C. Yearbook (1963) 63. As the Commission was informed by this communication of my point of view in this question, I abstained from speaking about the substance of Art. 37, inasmuch as I was in complete agreement with the draft proposed by the Special Reporter, Sir Humphrey Waldock.

56 Quaestiones juris public! libri duo (1737) II, Cap. 10. [The passage may be translated roughly as: “The civil law protects the contracts of individuals; good faith the contracts of princes. If you destroy good faith, you destroy the mutual intercourse of princes … and you destroy even international law itself.“—Ed.]
