The ongoing Syrian civil war calls for a re-evaluation of using force to protect human rights. This article does not rake over the much-debated issue of whether a right of humanitarian intervention exists as lex lata. Instead, it addresses the little reviewed normative issue of whether the right should exist in international law to support and reflect a pluralistic understanding of sovereignty. Despite advancements in international human rights law, international humanitarian law and international criminal law, this wider fabric of international law preserves Westphalian sovereignty and the principle of non-intervention. It denies any right of humanitarian intervention.
1 Art 2(4) UN Charter prohibits the ‘threat or use of force against the territorial integrity or political independence of any state’. In addition to State consent, the only explicit exceptions to this prohibition in the UN Charter are the inherent right of self-defence under art 51 UN Charter and force authorized by the UNSC pursuant to Chapter VII UN Charter.
2 For a recent summary of the issues and relevant State practice, see Rodley S, ‘Humanitarian Intervention’ in Weller M (ed), Oxford Handbook on the Use of Force in International Law (Oxford University Press 2015) 775 . In terms of the latest State practice, Syria represents an opportunity lost for those, like Koh, who support such a right and was looking to Syrian intervention as a law-making moment to crystallize a new norm of customary international law. H Koh, ‘Syria and the Law of Humanitarian Intervention (Part II: International Law and the Way Forward)’ (EJIL: Talk!, 4 October 2013) <http://www.ejiltalk.org/syria-and-the-law-of-humanitarian-intervention-part-ii-international-law-and-the-way-forward/>. Instead, Syria points to the contrary, suggesting a halt to any supposed momentum behind customary development. When military action finally occurred, it was not based on humanitarian intervention. The governments of the United States, Canada, Turkey, UK, Australia and France instead justified their military response against Daesh/ISIS in Syria on the basis of individual self-defence and/or the collective self-defence of Iraq. See UN Doc S/2014/695 (23 September 2014) (United States), UN Doc S/2015/221 (31 March 2015) (Canada), UN Doc S/2015/563 (24 July 2015) (Turkey), UN Doc S/2015/688 (7 September 2015) (UK), UN Doc S/2015/693 (9 September 2015) (Australia), UN Doc S/2015/745 (9 September 2015) (France). Russia's intervention was based on President Assad's consent. ‘Russia joins war in Syria: Five key points’, BBC News (1 October 2015) <http://www.bbc.co.uk/news/world-middle-east-34416519>.

6 Positivism as a jurisprudential ideology really took hold in the nineteenth century. This ‘positive revolution’ put the will and consent of States (rather than divine or natural law) at the centre of international rule making. See eg Neff SC in Evans MD (ed), International Law (4th edn, Oxford University Press 2014) 13–17 for a further discussion of this development. For an overview of the Peace of Westphalia and its impact on the evolution of international law and the rise of the sovereign State, see eg Gross L, ‘The Peace of Westphalia, 1648–1948’ (1948) 42(1) AJIL 240 .

33 This is particularly evident when contrasted with the UN Charter and international treaty systems that do not provide the same level of enforceability via compulsory jurisdiction and binding decisions. Similarly, the protection and enforcement of human rights in Africa, including via the African Commission on Human and Peoples’ Rights and the African Court on Human and Peoples’ Rights, face significant challenges. See M Schmidt, 391, and C Heyns and M Killander, 479 in Moeckli et al. (n 27) for an overview of these systems.

67 A State may, of course, invoke the international responsibility of another State for breaches of IHL under the International Law Commission (ILC) Articles on Responsibility of States for Internationally Wrongful Acts, with Commentaries, in Report of the International Law Commission on the work of its fifty-third session, UN Doc A/56/10 (2001) (ARSIWA). Such invocation is subject to peaceable dispute resolution, which will be discussed in Section II(E) below.
68 A belligerent reprisal ‘consists of action which would normally be contrary to [IHL] but which is justified because it is taken by one party to an armed conflict against another party in response to the latter's violation of [IHL] – for example, the use of prohibited weapons in retaliation for their prior use by an adversary’.

69 See Greenwood, ibid 309–15, for discussion of this development and the general trend against the use of belligerent reprisals, most notably pursuant to the express prohibitions stipulated by the four Geneva Conventions of 1949 and API.

73 Whilst an agreed definition is lacking under customary international law and the ICC has yet to have its jurisdiction ‘activated’ for such a crime, humanitarian intervention could potentially lead to individual criminal responsibility for senior military and political leaders for the crime of aggression. See Cryer et al (n 71) 312–33.

The art 2(4) prohibition is sometimes described as having this peremptory status (see eg Simma B, ‘NATO, the UN and the use of force: Legal Aspects’ (1999) 10 EJIL 1, 3). Such characterization is highly controversial however. In Nicaragua (n 54) para 190, the ICJ noted that the ILC and the United States (in its Memorial on the Merits in the case) characterized the prohibition on the use of force as jus cogens, but it has never ruled on this point.
