Some Reflections on Self-defence as an Element in Rules of Engagement

Armed Conflict and International Law: In Search of the Human Face

Abstract

From 16 to 20 June 2007, the International Security Assistance Force (ISAF) and the Taliban were engaged in a fierce battle over Chora, Afghanistan, resulting in many civilian casualties in and around that capital city. ISAF is a coalition of states established to contribute to the maintenance of security, but which through their frequent engagement in actual warfare have become parties to the armed conflict in Afghanistan. As a result, their actions are governed by international humanitarian law. This includes the prohibition of indiscriminate attacks, i.e. attacks expected to cause civilian casualties at a level excessive in relation to the military advantage anticipated. The hostilities in and around Chora have given rise to the question whether they might have violated this prohibition (a question ultimately answered in the negative). In this debate, self-defence was among the arguments raised in justification. Self-defence usually figures as a standard clause in the rules of engagement. These are texts which, established by commanders, permit or limit the use of force by their armed forces. The chapter briefly discusses the character of these instruments and of the clauses they contain. The focus is in particular on the self-defence clause. Self-defence may be individual or collective, and it may arise on three different levels: as national self-defence, unit self-defence or individual self-defence. National self-defence is the right for states to defend themselves against an attack or imminent attack. Unit self-defence is a notion generally accepted in military practice without having a firm legal basis in most countries. In contrast, individual self-defence is recognised in every domestic legal system. In the closing chapter, the chapter focuses on the relevant Dutch legal system, because the troops involved in the battle over Chora were Dutch forces and collective unit self-defence might have been at issue as an exculpatory argument in that case.

  4. 4.

    See also Cole 2009, p. 145: “Although positions on the legal basis for operations varied among ISAF contributing nations, most relied on a combination of the Security Council Resolution and the consent of the government of Afghanistan. In fact, many contributing nations were pleased to distance themselves from the US notion of the Global War on Terror, understanding it (rightly or wrongly) to be the concept of an international armed conflict against international terrorist organizations wherever they might be in the world”.

  5. 5.

    “On 11 August 2003 NATO assumed leadership of the ISAF operation, ending the six-month national rotations. The Alliance became responsible for the command, coordination and planning of the force, including the provision of a force commander and headquarters on the ground in Afghanistan”. NATO website ISAF, History para 3.

    The decision taken on 8 December 2005 by the NATO foreign ministers “was implemented on 31 July 2006, when ISAF assumed command of the southern region of Afghanistan from US-led Coalition forces, expanding its area of operations to cover an additional six provinces – Day Kundi, Helmand, Kandahar, Nimroz, Uruzgan and Zabul …” NATO website ISAF, Stage 3, to the south, para 2.

    The United States also claimed to wage war against Al Qaeda: the ‘War on Terror’. We do not enter into this claim here. On the characterisation of the situation as an international armed conflict, see also Cole 2009, p. 143: “Early coalition contributions to the invasion of Afghanistan also reflected the generally held view that this was an international armed conflict. The deployment of forces and the details of their rules of engagement (ROE) were based on the premise that this was a conflict between the ‘coalition of the willing’ on the one hand and Taliban forces, al Qaeda and the Afghan army on the other”.

  10. 10.

    In terms of jus in bello, the authorities were bound by Common Article 3 of the Geneva Conventions of 1949, as well as by the generally accepted humanitarian principles and rules of customary law. Afghanistan became a party to the Additional Protocols of 1977 to the 1949 Geneva Conventions only in 2009; Geneva Conventions (I, II, III, IV), Geneva, 12 August 1949, United Nations Treaty Series, Volume Number 75; Protocol (I) Additional to the Geneva Conventions of 12 August 1949, and relating to Protection of Victims of International Armed Conflicts, Geneva, 8 June 1977, United Nations Treaty Series, Volume Number 1125; Protocol (II) Additional to the Geneva Conventions of 12 August 1949, and relating to the Protection of Victims of Non-International Armed Conflicts, Geneva, 8 June 1977, United Nations Treaty Series, Volume Number 1125; Information available on the website of the International Committee of the Red Cross, http://www.icrc.org/.

    Our conclusion differs theoretically, though not practically, from views expressed by Boddens Hosang and Ducheine who, in line with an opinion expressed by the Dutch Government, hold that while the relatively quiet phases of ISAF presence do not qualify as an armed conflict, the Chora incident and similar events represent temporary and local armed conflicts leading to de jure applicability of the jus in bello. Ducheine and Pouw 2009, also quoting Boddens Hosang 2009.

    Common Article 3 to the Geneva Conventions of 1949, supra note 10, provides in part that “each Party to the conflict shall be bound to apply, as a minimum, the following provisions:

    1) Persons taking no active part in the hostilities, including members of armed forces who have laid down their arms and those placed hors de combat by sickness, wounds, detention, or any other cause, shall in all circumstances be treated humanely, without any adverse distinction founded on race, colour, religion or faith, sex, birth or wealth, or any other similar criteria.

    […]

    2) The wounded and sick shall be collected and cared for.

    […]”.

    A particularly notorious case was the attack on the World Trade Center, with Al Qaeda claiming that the people working there could be equalled to combatants. In general, the past ‘liberation wars’ as well as recent cases of ‘asymmetric warfare’ in the Middle East and elsewhere provide an endless stream of acts violating the most fundamental principles of IHL.

    NATO classifies situations of this type in politically even more neutral terms as Non-Article 5 Crisis Response Operations, i.e., situations that do not (as required in Article 5 of the North Atlantic Treaty) arise from an armed attack against one or more of the member states that would be considered an attack against them all; See AJP-3.4 (A) 2010.

    The cards provide that before opening fire in self-defence, and “if time and circumstances permit … [y]ou are to warn by shouting”. This suggests that the model RoE presented in the Handbook are soldiers cards. These characteristically contain far less policy, if any, than do the RoE directed at higher levels.

    An important exception is the United States, where unit self-defence is not merely a right but an obligation, and individual self-defence is a derivate of unit self-defence: “Unit commanders always retain the inherent right and obligation to exercise unit self-defense in response to a hostile act or demonstrated hostile intent. Unless otherwise directed by a unit commander as detailed below, military members may exercise individual self-defense in response to a hostile act or demonstrated hostile intent. When individuals are assigned and acting as part of a unit, individual self-defense should be considered a subset of unit self-defense. As such, unit commanders may limit individual self-defense by members of their unit.” Operational Law Handbook 2012, Chapter 5, E 2, a (1) Inherent Right of Self-Defense.

  34. 34.

    For an author who paid particularly close attention to the notion of unit self-defence, see Stephens 1998.

    The term ‘individual self-defence’ is also used as the counterpart of ‘collective self-defence’.
