Abstract

The armed conflict in Afghanistan since 2001 has raised manifold questions pertaining to the humanitarian rules relative to the conduct of hostilities. In Afghanistan, as is often the case in so-called asymmetric conflicts, the geographical and temporal boundaries of the battlefield, and the distinction between civilians and fighters, are increasingly blurred. As a result, the risks for both civilians and soldiers operating in Afghanistan are high. The objective of this article is to assess whether – and if so how much – the armed conflict in Afghanistan has affected the application and interpretation of the principles of distinction, proportionality, and precaution – principles that form the core of legal rules pertaining to the conduct of hostilities.

1 The armed opposition operating against the Government of the Islamic Republic of Afghanistan and the international military presence is commonly referred to as the ‘Taliban’, who describe themselves as the Islamic Emirate of Afghanistan. This is a shorthand for a fragmented alliance between different groups such as the Quetta Shura Taliban in Southern Afghanistan, Hezb-i Islami Gulbuddin (HiG) and Hezb-i Islami Khalis in the east, and the Haqqani Network.

If unable to assess the risk of civilian presence, fires are prohibited, except under [one] of the following two conditions (specific conditions deleted due to operational security; however, they have to do with the risk to ISAF and Afghan forces).’ See ISAF, General Petraeus issues updated tactical directive: emphasizes ‘disciplined use of force’, News Release, 2010-08-CA-004, Kabul, 4 August 2010, available at: http://www.isaf.nato.int/article/isaf-releases/general-petraeus-issues-updated-tactical-directive-emphasizes-disciplined-use-of-force.html (last visited 15 March 2011).

7 See S. Ojeda, above note 5, pp. 358–359. In accordance with the jurisprudence of the International Criminal Tribunal for the former Yugoslavia (ICTY), an international armed conflict exists ‘whenever there is a resort to armed force between States’. See ICTY, Prosecutor v. Dusko Tadić, Decision on the Defence Motion for Interlocutory Appeal on Jurisdiction (Appeals Chamber), 2 October 1995, para. 70. According to the commentary to the Geneva Conventions of 1949, an international armed conflict takes place whenever there is ‘Any difference arising between two States and leading to the intervention of armed forces’. Jean S. Pictet (ed.), The Geneva Conventions of 12 August 1949, Commentary, Geneva Convention for the Amelioration of the Condition of the Wounded and Sick in Armed Forces in the Field, Geneva, ICRC, 1952, p. 32.

8 Note that this expression does not depict a ‘third’ type of armed conflict but covers non-international armed conflicts with an ‘international’ dimension. The expression is used in situations where a state (or a multinational force) becomes a party to a pre-existing non-international armed conflict. Such an intervention may result in three outcomes: (1) the existing armed conflict remains a non-international armed conflict if a state or multinational force supports another state against the armed opposition; (2) the armed conflict is transformed into an international armed conflict if the acts of the armed opposition can be attributed to the intervening state or multinational force; or (3) it develops into a ‘mixed conflict’, where the relations between the parties are governed in part by the rules of international armed conflict and in part by those of non-international armed conflict.

10 Operation Enduring Freedom was based upon UN Security Council resolution 1368 of 12 September 2001, recognizing the individual and collective right of self-defence in accordance with the UN Charter, condemning the ‘terrorist attacks’ in the United States, and regarding them as a threat to international peace and security. In addition, NATO invoked Article 5 of the North Atlantic Treaty, which considers an armed attack against one or more NATO parties as an attack against all of them. See Article 5 of the North Atlantic Treaty of 4 April 1949; NATO Update, ‘Invocation of Article 5 confirmed’, 2 October 2001, available at: http://www.nato.int/docu/update/2001/1001/e1002a.htm (last visited 14 March 2011).

21 A clear and uniform definition of what constitutes a non-international armed conflict does not exist in international law. However, it is generally accepted that the existence of such a conflict is based on objective criteria, namely the intensity of the violence and the organization of the parties.

45 The ICTY has aptly noted that: ‘After the First World War, the application of the laws of war moved away from a reliance on reciprocity between belligerents, with the consequence that, in general, rules came to be increasingly applied by each belligerent despite their possible disregard by the enemy. The underpinning of this shift was that it became clear to States that norms of international humanitarian law were not intended to protect State interests; they were primarily designed to benefit individuals qua human beings’.

59 In non-international armed conflicts, the membership approach is not uncontested: see e.g. Noam Lubell, Extraterritorial Use of Force Against Non-state Actors, Oxford, Oxford University Press, 2010, pp. 148–155. In its study on direct participation, the ICRC adopted a membership approach based on continuous combat function. See ICRC, Interpretive Guidance on the Notion of Direct Participation in Hostilities under International Humanitarian Law, ICRC, Geneva, May 2009, pp. 31–36.

60 Note that civilians also include members of the Taliban without continuous combat function and who are not directly participating in hostilities. At least in the period between 11 September 2001 and 1 May 2003, the Operation Enduring Freedom rules of engagement did not declare any forces hostile. Instead, they relied upon the notion of ‘likely and identifiable threat (LIT)’ and positive identification (PID) thereof, which caused confusion among the troops. The forces were trained for the usual three-pronged approach, including declaration of hostile forces (targetable at any time), addressing direct participation in hostilities, and, for situations not connected to hostilities, incorporating the concept of self-defence. See Center for Law and Military Operations, above note 54, pp. 96–103; Michael N. Schmitt, ‘Targeting and international humanitarian law in Afghanistan’, in M. N. Schmitt, above note 5, p. 314.

61 It is estimated that about a million guns are held by Afghan civilians, which equates to about 4.4 firearms per 100 people. See data compiled by GunPolicy.org, available at: http://www.gunpolicy.org/firearms/region/afghanistan (last visited 22 March 2011).

68 In its country report on Colombia (1999), the Inter-American Commission of Human Rights (IACHR) emphasized that, under Article 4 ACHR, the use of lethal force in law enforcement operations could not lawfully be based on mere suspicion or on collective criteria, such as membership in a group. According to the report: ‘the police are never justified in depriving an individual of his life based on the fact that he belongs to a “marginal group” or has been suspected of involvement in criminal activity. Nor may the police automatically use lethal force to impede a crime or to act in self-defence. The use of lethal force in such cases would only be permissible if it were proportionate and necessary’; IACHR, Report Colombia 1999, Chapter IV, para. 213.

69 Moreover, the justification of so-called collateral damage, while it is not illegal per se under international human rights law, would be far more difficult than it is under IHL.

87 In the application of joint fires in Afghanistan, for instance, several factors need to be taken into account before an attack is permitted. This includes, inter alia, an assessment as to whether or not the target makes an effective contribution to the enemy military action and as to whether its destruction offers a definite military advantage (i.e. whether it is a military objective). Guidance for the Application of Joint Fires, Annex B to HQ ISAF SOP, Dated 06, extract presented at the Rules of Engagement Workshop, International Institute of Humanitarian Law, Sanremo, 13–17 September 2010. According to Joint Pub 3-09, Doctrine for Joint Fire Support, 12 May 1998, p. I–1, joint fires are ‘fires produced during the employment of forces from two or more components in coordinated action toward a common objective’.

106 Footnote 37 of the elements of crime of Article 8 para. 2(b)(iv) of the Rome Statute contains an exception to the mental requirements laid out in paragraph 4 of the ‘General Introduction’, according to which, with respect to mental elements associated with elements involving value judgment, such as those using the terms ‘inhumane’ or ‘severe’, it is not necessary that the perpetrator personally completed a particular value judgement, unless otherwise indicated. See Knut Dörmann, Elements of War Crimes under the Rome Statute of the International Criminal Court: Sources and Commentary, Cambridge University Press, Cambridge, 2003, p. 161. Different views have been expressed on the interpretation of footnote 37. However, on the whole a rather subjective standard seems to be endorsed in this regard. There appears to be agreement between states that this footnote should not lead to the result of exonerating a reckless perpetrator who knows the anticipated military advantage and the expected incidental damage or injury but gives no thought to evaluating the possible excessiveness of the incidental injury or damages; ibid., p. 165.

107 ‘Final report to the prosecutor’, above note 86, para. 50, states: ‘Although there will be room for argument in close cases, there will be many cases where reasonable military commanders will agree that the injury to noncombatants or the damage to civilian objects was clearly disproportionate to the military advantage gained’. In the Kupreškić case, the ICTY relied on the Martens Clause as a minimum reference and argued on this basis that the prescriptions – in this case the prescriptions of Articles 57 and 58 of Additional Protocol I – must be interpreted so as to construe as narrowly as possible the discretionary power to attack belligerents and, by the same token, so as to expand the protection accorded to civilians; ICTY, Prosecutor v.

A feasibility assessment is necessarily contextual and what is feasible also hinges on the reconnaissance resources available to the attacker. It is therefore generally accepted that, in practice, technologically advanced parties may be bound to a higher standard than those parties who lack similarly advanced reconnaissance means. See also Protocol on Prohibitions or Restrictions on the Use of Mines, Booby-Traps and Other Devices (Protocol II), Geneva, 10 October 1980, Article 3(4). Accordingly, ‘[f]easible precautions are those precautions which are practicable or practically possible taking into account all circumstances ruling at the time, including humanitarian and military considerations’.

121 The presumptions entailed in Article 51 para. 1 and Article 52 para. 3 of Additional Protocol I have remained the subject of controversy, however. Particularly in the case of non-international armed conflicts, no clear rule regulates situations where the character of a person is in doubt. Nevertheless, it seems appropriate to demand the same careful and balanced approach in deciding upon the status of people as is required in international armed conflicts. See J.-M. Henckaerts and L. Doswald-Beck, above note 44, Rule 6, pp. 23–24.

122 Public Prosecutor General of the Federal Court of Justice, above note 103. Note that airstrikes seem to have been limited to troops-in-contact (TIC) situations.

129 The ICRC Commentary provides that giving a warning may be inconvenient when the element of surprise in the attack is a condition of its success: see Y. Sandoz, C. Swinarski, and B. Zimmermann (eds), above note 80, para. 2223.

130 For this terminology and definition of these paradigms, see Nils Melzer, Targeted Killing in International Law, Oxford University Press, Oxford, 2008, in particular pp. 85–90 and 269–298 respectively.

131 Considerable debate exists regarding the extraterritorial application of human rights. See, inter alia, Jann K. Kleffner, ‘Human rights and international humanitarian law: general issues’, in Terry D. Gill and Dieter Fleck (eds), The Handbook of the International Law of Military Operations, Oxford University Press, Oxford, 2010, p. 69 onwards; and N. Lubell, above note 59, pp. 193–235. For instance, according to Article 1 of the European Convention for the Protection of Human Rights and Fundamental Freedoms (ECHR), the rights and freedoms of the convention must be secured ‘to everyone within their [the High Contracting Parties’] jurisdiction'. In its case law, the European Court of Human Rights (ECtHR) particularly relies on the criterion of ‘effective control’ in order to affirm the extraterritorial applicability of human rights. See, ECtHR, Loizidou v. Turkey, Preliminary Objections (Grand Chamber), 23 February 1995, paras. 61–64; ECtHR, Öcalan v. Turkey, Judgment (Grand Chamber), 12 May 2005, para. 91; ECtHR, Al-Saadoon and Mufdhi v. UK, Admissibility Decision, 30 June 2009, paras. 87–88. Contrary to the ECHR, the wording of the International Covenant on Civil and Political Rights (ICCPR) is more ambiguous, as its Article 2(1) requires a state party to ‘respect and ensure to all individuals within its territory and subject to its jurisdiction the rights’ set out in the convention. However, the Human Rights Committee (HRC) has affirmed the possible extraterritorial application in several instances. See, most prominently, HRC, General Comment No. 31: Nature of the General Legal Obligation Imposed on States Parties to the Covenant, 26 May 2004, UN Doc. CCPR/C/21/Rev.1/Add.13, para. 10; HRC, Concluding Observations: United States of America, 2006, UN Doc. CCPR/C/USA/CO/3, para. 10; HRC, Lopez Burgos v. Uruguay (Communication No. 52/1979), 29 July 1981, UN Doc. CCPR/C/13/D/52/1979, para. 12. Finally, the rights and freedoms in the American Convention on Human Rights must be respected and ensured ‘to all persons subject to their [the state parties’] jurisdiction' (Article 1). See, e.g., Inter-American Commission on Human Rights, Armando Alejandre, Jr., et al. v. Republic of Cuba, Case Report No. 86/99, 29 September 1999, para. 23.

Afghanistan ratified the ICCPR of 23 March 1976 on 24 April 1983 and it is thus binding for all Afghan forces maintaining a checkpoint. For Coalition forces, the applicable human rights obligations will depend on the treaties that they have ratified, which raises the question whether and to what degree these human rights instruments are applicable extraterritorially.

148 See, e.g., HRC, Suarez de Guerrero v. Colombia, above note 147, paras. 13.2–3. While similar, the ECHR has set out a slightly different system. Article 2(2) of the ECHR is violated if a deprivation of life is not ‘absolutely necessary’ to achieve one of the listed justification purposes. Like the other human rights systems, the ECHR also requires that the use of force is proportionate and that precautions be taken in order to ‘avoid or minimise, to the greatest extent possible’ any risk to life or the recourse to lethal force. See, e.g., ECtHR, Case of Ergi v. Turkey, No. 66/1997/850/1057, 28 July 1998, paras. 79–81, stating that government forces setting up an ambush in the vicinity of a village, and thus exposing the villagers to the risk of crossfire, should have taken adequate precautions.

159 Operations and cross-border attacks in Pakistan present manifold challenging questions not only from a human rights or IHL angle but also from a jus ad bellum perspective that are beyond the scope of this article. See, e.g., Report of the Special Rapporteur on Extrajudicial, Summary or Arbitrary Executions, above note 66, pp. 10–15 and 25.

160 See Chatham House, above note 154, p. 5, where O'Connell notes that there are about six to seven casualties per attack, out of which usually only one person was on the hit list. This also raises concern about how those planning or deciding upon an attack carry out proportionality assessments. For an argument that the advanced technological capabilities of UAVs allowing for virtual ‘persistent surveillance’ (and thus making more relevant information available) lead to stricter requirements for targeting decisions, proportionality, and precautions, see J. M. Beard, above note 110, especially pp. 420, 428–442, and 444.

161 In cases where the drone is operated, in the context of an armed conflict, by a civilian contractor or by intelligence agencies (e.g. the CIA), the pilot would participate directly in hostilities and could potentially be targeted. In addition, the pilot's participation could raise issues regarding criminal liability and detention status.
