22 In the course of its Memorial to the Court, the United Kingdom argued that: “since the adoption of the Convention in 1907, States have in their practice treated its provisions as having been received into general international law. Even Germany, who in the wars of 1914–1918 and 1939–1945 was guilty of serious breaches of the Convention, publicly professed to be complying with its provisions. The Allied Powers in both wars held themselves bound by the Convention and throughout observed the provisions relating to notification”: ICJ Pleadings, Vol. 1, p. 39.

36 See, however, the Dissenting Opinion of Judge Koroma, considering that: “Additional Protocol I (…) constitutes a restatement and a reaffirmation of customary law rules based on the earlier Geneva and Hague Conventions. To date, 143 States have become parties to the Protocol, and the customary force of the provisions of the Protocol are not based on the formal staus of the Protocol itself”: ibid., p. 580.

52 “Il ne fait pas de doute pour moi que la plupart des principes et règles du droit humanitaire et, en tout cas, les deux principes interdisant l'un l'emploi des armes à effets indiscriminés et l'autre celui des armes causant des maux superflus, font partie du jus cogens. La Cour a évoqué cette question dans le présent avis; mais elle a toutefois déclaré qu'elle n'avait pas à se prononcer sur ce point dans la mesure où la question de la nature du droit humanitaire applicable aux armes nucléaires ne rentrait pas dans le cadre de la demande que lui a adressée l'Assemblée générale des Nations Unies. La Cour n'en a pas moins expressément considéré ces règles fondamentales comme ’des règles intransgressibles du droit international coutumier’”, Legality of the Threat or Use of Nuclear Weapons, op. cit.

53 Ibid., p. 496. He notices that Judge Roberto Ago considered in 1971 in his course at The Hague Academy of International Law that the rules of jus cogens include: “the fundamental rules concerning the safeguarding of peace, and notably those which forbid recourse to force or threat of force; fundamental rules of a humanitarian nature (prohibition of genocide, slavery and racial discrimination, protection of essential rights of the human person in time of peace and war)”.

84 By seven votes to seven, the Court concludes with the President's casting vote that: “the threat or use of nuclear weapons would generally be contrary to the rules of international law applicable in armed conflict, and in particular the principles and rules of humanitarian law. However, in view of the current state of international law, and of the elements of fact at its disposal, the Court cannot conclude definitively whether the threat or use of nuclear weapons would be lawful or unlawful in an extreme circumstance of self-defence, in which the very survival of a State would be at stake”. By doing so, the Court seems to blur the traditional distinction between jus ad bellum and jus in bello. For a critical commentary on the position of the Court, see in particular: E. David, “Le statut des armes nucléaires à la lumière de l'avis de la CIJ du 8 juillet 1996”, in Boisson de Chazoumes, L.. & Sands, P.
