4 Protocol Additional to the Geneva Conventions of 12 August 1949, and Relating to the Protection of Victims of International Armed Conflicts, Geneva, 8 June 1977, entered into force 7 December 1978 (hereinafter ‘Additional Protocol I’).

7 IHRL evidently binds the state within its national territory, but also applies in cases where its military exerts its power or effective control over individuals abroad: see for example International Court of Justice (ICJ), Armed Activities on the Territory of the Congo (Democratic Republic of the Congo v. Uganda), Judgment, ICJ Reports 2005, para. 216. See also Cordula Droege, ‘Elective affinities? Human rights and humanitarian law’, International Review of the Red Cross, No. 871 (2008), pp. 509–20; Françoise Hampson, ‘The relationship between international humanitarian law and human rights law from the perspective of a human rights treaty body’, International Review of the Red Cross, No. 871 (2008), pp. 566–72.

8 For example, the Rome Statute of the International Criminal Court, 17 July 1998, entered into force 1 July 2002 (applicable to states parties in the context of repression of the most serious international crimes); the United Nations Convention on the Law of the Sea, 10 December 1982, entered into force 16 November 1994 (applicable to states parties in the context of the suppression of piracy on the high seas); and the International Convention for the Suppression of Terrorist Bombings, 15 December 1997, entered into force 23 May 2001 (applicable to states parties in the context of domestic anti-terror operations).

11 Art. 51(5)(b), Additional Protocol I.

12 See, for example, Art. 6(1), International Covenant on Civil and Political Rights (ICCPR), 16 December 1966, entered into force 23 March 1976; Guerrero v. Colombia (R.11/45), ICCPR, A/37/40 (31 March 1982) 137, para. 13.2–13.3.

17 Indeed, the Geneva Convention of 1864 – the first IHL treaty – was the result of a diplomatic effort following Henry Dunant's horrific experience at the Battle of Solferino in 1859, where the military medical services of the battling French and Austrian troops were totally insufficient to deal with the scale of casualties in the field.

18 Geneva Convention for the Amelioration of the Condition of the Wounded and Sick in Armed Forces in the Field of 12 August 1949 (hereinafter GC I); Geneva Convention for the Amelioration of the Condition of Wounded, Sick and Shipwrecked Members of Armed Forces at Sea of 12 August 1949 (hereinafter GC II); Geneva Convention Relative to the Treatment of Prisoners of War of 12 August 1949 (hereinafter GC III); Geneva Convention Relative to the Protection of Civilian Persons in Time of War of 12 August 1949 (hereinafter GC IV); all of which entered into force 21 October 1950. Every state has ratified these Conventions.

19 Where the Additional Protocols are not applicable qua treaty, most of their substantive provisions are applicable in the form of customary international law. See Jean-Marie Henckaerts and Louise Doswald-Beck, Customary International Humanitarian Law, ICRC/Cambridge University Press, Cambridge, 2005.

20 Some provisions of these treaties have also taken on the status of customary international law.

21 As supplemented by Additional Protocol I. IHRL does, however, continue to play a role, with IHL remaining the lex specialis.

23 Protocol Additional to the Geneva Conventions of 12 August 1949, and Relating to the Protection of Victims of Non-International Armed Conflicts (Protocol II), of 8 June 1977, entered into force 7 December 1978 (hereinafter Additional Protocol II).

27 As discussed above, states parties are bound by the four Geneva Conventions, Additional Protocol I, and a long list of treaties governing various limitations upon means and methods of warfare. Non-parties are bound by applicable customary IHL.

38 As a neutral and independent humanitarian body, the ICRC is competent to classify conflicts to ensure that it maintains a legally consistent approach and protects the actual and potential victims of conflict. However, in order to preserve its neutrality, it will not generally publicize its findings in circumstances where it might be perceived as taking a controversial position regarding the jus ad bellum.

39 For a discussion of this principle, which is not without controversy, see Sassoli, above note 31, pp. 8–9.

43 On 27 November 1991, representatives of various parties to the conflict including the Federal Republic of Yugoslavia and the Republic of Croatia agreed in a Memorandum of Understanding to implement the full range of Geneva Conventions and their Protocols, but the agreement explicitly stated that it would ‘not affect the legal status of the parties to the conflict’. See Michele Mercier, Without Punishment: Humanitarian Action in the Former Yugoslavia, East Haven, London, 1995, Appendix: Document IV, pp. 195–8.

49 As has been graphically illustrated by recent armed conflicts between MONUC troops and armed factions in the eastern Democratic Republic of Congo.

50 Both the Coalition states and Afghanistan were parties to the four Geneva Conventions, but neither Afghanistan nor the United States is party to Additional Protocol I.

51 Art. 4(A)(1) of GC III defines ‘members of the armed forces of a Party to the conflict’ as a category of individuals entitled to prisoner of war protection (i.e. combatants) without the requirement of fulfilling the four ‘militia’ prerequisites in 4(A)(2). To qualify as armed forces, they must have been under a command responsible to the Party and subject to an internal disciplinary structure per Art. 43(1) of Additional Protocol I. If we accept that the Taliban was the de facto government of Afghanistan at the time (they controlled 90 per cent of its territory), it is strongly arguable that their armed forces met all of these requirements and thus would have qualified as combatants.

52 For example, making the civilian population the object of an attack during an international armed conflict is a war crime to which universal jurisdiction applies. Henckaerts and Doswald-Beck, above note 19, Rules 156 and 157.

62 And, potentially, as a matter of opinio juris.

63 See Integrating the Law, above note 5.

64 Even if it chooses not to exercise that right in the name of peace: see Art. 6(5) of Additional Protocol II.

65 For example, IHL accepts that civilians can knowingly be killed as collateral damage as long as that damage is outweighed by the concrete and direct military advantage achieved in an attack (see Art. 51(5)(b) of Additional Protocol I). In the absence of a definite legal qualification, it is difficult to reconcile this provision of IHL with the right to life, as interpreted in peacetime, protected by IHRL.
