25 The difference between the law of treaties and law of state responsibility, drawn by the ICJ, is relevant here: ‘A determination of whether a convention is or is not in force, and whether it has or has not been properly suspended or denounced, is to be made pursuant to the law of treaties. On the other hand, an evaluation of the extent to which the suspension or denunciation of a convention, seen as incompatible with the law of treaties, involves the responsibility of the State which proceeded to it, is to be made under the law of state responsibility’. Gabčíkovo-Nagymaros Project (Hungary/Slovakia), Judgment of 25 September 1997, [1997] ICJ Rep. 7, at 38. The rules regarding waiver and acquiescence operate in relation to both above categories either in relation to the continued substantive applicability of the rule, or in relation to the wrongful consequences once the rule has been breached. The former aspect is governed by the law of treaties and the latter one by the law of state responsibility. In both contexts the ILC has admitted that these arrangements do not prejudice the effect of jus cogens; for details, see Orakhelashvili, A., Peremptory Norms in International Law (2006), Chapter 11.Google Scholar

29 According to Article 2 ILC Articles, supra note 27: ‘There is an internationally wrongful act of a State when conduct consisting of an action or omission: (a) Is attributable to the State under international law; and (b) Constitutes a breach of an international obligation of the State.’

32 Talmon, supra note 2, at 986. Emphasis in original. In support of this proposition, Talmon refers to Cannizzaro, E., ‘A Higher Law for Treaties?’, in Cannizzaro, E. (ed.), The Law of Treaties beyond the Vienna Convention (2011), 425Google Scholar at 434, 439; but Cannizzaro in the same contribution has admitted that in certain cases there can be a conflict between jus cogens and immunity (at 439, last paragraph, suggesting the balancing test). Talmon's allusion to Cassese, A., ‘When May Senior State Officials Be Tried for International Crimes? Some Comments on The Congo v. Belgium Case’, (2002) 13 EJIL 853CrossRefGoogle Scholar, at 867, is also counterfactual, for Cassese was maintaining the distinction between substantive and procedural rules only in relative terms as Arrest Warrant (supra note 30) had suggested it. Cassese had suggested nothing that would justify the approach either in Jones v. Saudi Arabia ([2006] UKHL 16) or in Germany v. Italy (supra note 1), but has instead supported the primacy of jus cogens over immunities. See A. Cassese, International Law (2005), at 108.

39 For a detailed analysis of jurisprudence to the effect that human rights law and humanitarian law create rights for individuals, not disposable by transactions between states, see Orakhelashvili, supra note 25, Chapter 4. A similar effect can be attributed to the individual right to obtain reparation for violation of humanitarian law, for the detailed analysis of which under Article 3 of the 1907 Convention (IV) respecting the Laws and Customs of War on Land and relevant customary law see Fujita, H., Suzuki, I., and Nagano, K.

46 There can, however, be convergence between the two. Most human rights and humanitarian-law treaties are conventional equivalents of customary jus cogens, not subject to derogation prohibited under Article 53 of the 1969 Vienna Convention (see supra note 33). This was recognized by the ILC in the 1960s when the codification of the 1969 Vienna Convention was under way, and overwhelmingly reflected in judicial practice and doctrine since then. Evidence is discussed in detail in Orakhelashvili, supra note 25, Chapter 4. Most recently, the decision of the European Court of Human Rights in Othman specified that ‘UNCAT reflects the clear will of the international community to further entrench the ius cogens prohibition on torture by taking a series of measures to eradicate torture and remove all incentive for its practice’. Othman (Abu Qatada) v. The United Kingdom, Application No. 8139/09, Judgment of 17 January 2012 (not yet published), at para. 266. This point further undermines the argument that the denial of the immunity of a former head of state by the House of Lords of England and Wales in R v. Bow Street Stipendiary Magistrate and Others, ex parte Pinochet Ugarte (No. 3) [1999] 2 All E.R. 97 was undertaken on the basis of the 1984 Convention against Torture and Other Cruel, Inhuman or Degrading Treatment or Punishment, 1468 UNTS 85, as completely separate from jus cogens. The 1984 Torture Convention and jus cogens were also interchangeably used by the House of Lords of England and Wales in A and Others v. Secretary of State for the Home Department [2005] UKHL 71.

47 The ILC referred to the effect of jus cogens on ‘any [conflicting] act or situation’. Report of the International Law Commission on the work of its eighteenth session (4 May–19 July 1966) [1966] Yearbook of the International Law Commission 2, at 261. The International Criminal Tribunal for the Former Yugoslavia observed in Furundzija that ‘[t]he fact that torture is prohibited by a peremptory norm of international law has other effects at the inter-state and individual levels. At the inter-state level, it serves to internationally de-legitimise any legislative, administrative or judicial act authorising torture. Prosecutor v. Furundzija, Judgment, Case No. IT-95–17/1-T, T.Ch., 10 December 1998, at para. 155. Pursuant to Furundzija, Lord Browne-Wilkinson in Pinochet (supra note 46) observed that ‘The jus cogens nature of the international crime of torture justifies states in taking universal jurisdiction over torture wherever committed’. In this same case, Lord Hope was of the view that ‘acts the prohibition of which has acquired the status under international law of jus cogens . . . [compel] all states to refrain from such conduct under any circumstances and imposes an obligation erga omnes to punish such conduct’. Furthermore, Lord Millett added that ‘[i]nternational law cannot be supposed to have established a crime having the character of a jus cogens and at the same time to have provided an immunity which is co-extensive with the obligation it seeks to impose’. Overall, five Law Lords subscribed to such extra-conventional effect of jus cogens: Lord Nicholls, Pinochet, 939–940; Lord Steyn, ibid., 945–946; Lord Hutton, ibid., 165–166; Lord Millett, ibid., 179. Most recently, the Swiss Federal Tribunal reiterated the same view in A v. Ministère public de la confédération, Tribunal pénal fédéral, Numéro de dossier BB.2011.140, Judgment of 25 July 2012, at paras. 5.3.5 and 5.4.3. See further notes 48 and 52–5 infra and the accompanying text, to a similar effect.
