Abstract

On 27 June 2017, in the Stichting Mothers of Srebrenica case, The Hague Court of Appeal applied the effective control test in determining attribution and found that the Netherlands was responsible for the failure of the Dutch battalion (Dutchbat) acting as a part of the UN Protection Force (UNPROFOR) to protect civilians from the Srebrenica massacre in 1995. This judgment is of considerable significance because the court renounced the preventive approach to the effective control test, to which the Dutch courts had repeatedly declared their adherence, and reverted to the traditional (presumptive) approach. The preventive interpretation was originally proposed with a view to justifying much broader attribution to troop-contributing nations (TCNs). However, quite interestingly, the Court of Appeal reached the conclusion that the Dutchbat’s conduct was attributable to the Netherlands without recourse to the preventive approach. The present study argues that the legal framework for the attribution of UN peacekeepers’ conduct has developed in such a manner that the fair allocation of responsibility and the effectiveness of UN peacekeeping operations are in equilibrium. In that sense, the effective control test should be located at the interface between the law of international responsibility and the law of international organizations. It is illustrated that not only does the preventive interpretation fail to strike a fair balance between the institutional considerations and the need to provide remedies for victims of peacekeepers’ misconduct, but also the presumptive approach may lead to effective remedies while having due regard for the institutional considerations.

46 Zwanenburg, supra note 6, at 101–2. Although Gaja observed in general terms that ‘conduct does not necessarily have to be attributed exclusively to one subject only’ (Gaja, supra note 23, at 4) and ‘dual attribution of the same conduct cannot be excluded’ (ibid., at 10), neither his report nor the ARIO commentary provides a conclusive answer on this point as far as UN peacekeeping operations are concerned (ibid., at 14; Report of the ILC (2011), supra note 29, at 56–60). It is true that the ECtHR implied that attribution to the UN may be compatible with attribution of the same conduct to TCNs (Al-Jedda v. the United Kingdom, Judgment of the Grand Chamber of the ECtHR of 7 July 2011, Application no. 27021/08, para. 80), but the findings concerned a UN-authorized operation (Palchetti, supra note 33, at 24).

52 In Behrami and Saramati, the ECtHR placed a high premium on the institutional interests in attributing the misconduct committed in the course of the UN-authorized operation in Kosovo to the UN (Behrami and Saramati, supra note 37, paras 132–41) to the point of being criticized for putting too much emphasis on them (see, e.g., A. Sari, ‘Jurisdiction and International Responsibility in Peace Support Operations: The Behrami and Saramati Cases’, (2008) 8 Human Rights Law Review 151, at 164). It is true that the legality under the institutional law of the UN is a different legal issue from attribution, but the institutional considerations should not be disregarded.

The commentary refers to, as a clear example of an off-duty act, a case where a member of the United Nations Interim Force in Lebanon engaged in moving explosives to the territory of Israel. However, peacekeepers may take advantage of their functions in committing wrongdoings even when they are off-duty. It may happen that a peacekeeper commits a robbery on a day off with a weapon supplied for the purpose of a peacekeeping operation. Thus, as the commentary points out, ‘[o]ne would then have to examine whether the ultra vires conduct in question is related to the functions entrusted to the person concerned’.

78 Ryngaert, supra note 51, at 155: Ryngaert continued that ‘[t]his is not too revolutionary an idea, as it was already implied by Seyersted in his 1966 monograph’, ibid., at 156. Seyersted was quoted as arguing that ‘if a Force is under national command, the Organization has no legal responsibility for it and does not represent it internationally’ (Seyersted, supra note 4, at 411). However, he continued that ‘[t]hus, the United Nations Force in Korea was under the international responsibility of the United States and, to a lesser degree, of the other participating States. The responsibility for a Force established under the Uniting for Peace resolution would be divided between the State in command and the other participating States in a similar manner’ (ibid., at 411–12). Therefore, given that he placed emphasis on the operational level of authority and control (ibid., at 411), it seems that Seyersted represented the traditional approach rather than foretold the preventive interpretation.

108 It is said that the Court of Appeal’s judgment in Nuhanović was based on ‘the preventative rationale’: Ryngaert, supra note 51, at 173.

109 Under the current legal system, as Gaja insightfully implied, attribution is not premised on control itself, but the existence of a functional link. Control serves as an indicative factor in establishing the functional link: Gaja, supra note 23, at 7, fn. 28.

However, it could be noted that Dannenbaum conceived that this inflexibility has an advantage in terms of protecting vulnerable victims: Dannenbaum, T., ‘Public Power and Preventive Responsibility: Attributing the Wrongs of International Joint Ventures’, in Nollkaemper, A. and Jacobs, D.

116 As admitted by Dannebaum, even a scenario in which a peacekeeper commits a wrongdoing while acting within their discretion as granted by the UN commander rarely comes about: Dannenbaum, supra note 12, at 165–6.

118 According to Dannenbaum, a threshold should be high in the case of attribution, whereas whether a state has met the obligation of ‘preventive due diligence’ may be assessed in a less strict manner. For him, the difference between these two norms appears to be a matter of degree: Dannenbaum, supra note 112, at 212–15.

122 It might be noted that, however, what matters in terms of the customary law-making process is that the UN, in generating the practice of assuming full responsibility for peacekeepers’ conduct, has consistently retained the perception that attribution to TCNs would have significant repercussions on troop contributions for future operations.

123 Such involvement by TCNs as falls short of interruption of the UN chain of command does not negate attribution to the UN since the functional link between the peacekeeper and the UN is not broken: Palchetti, supra note 33, at 26.

130 ‘[I]f the United Nations is properly attributed with full and exclusive responsibility for such wrongs, the inadequacy of its remedial mechanisms is not reason enough to attribute responsibility to another actor. However, the current situation emphasizes the importance of carefully considering how responsibility for peacekeepers’ human rights abuses should be attributed’ (ibid., at 128–9).

133 The UN is under the obligation to provide alternative means for dispute settlement as a counterpart of its immunity under Art. VIII Sec. 29 of the Convention on the Privileges and Immunities of the UN: Okada, supra note 131, at 47–8. It is sometimes contended that ‘states might be held responsible for failing to pressure the organization to institute a robust and transparent claims review system’: Dannenbaum, supra note 112, at 224.
