Investigating from Afar: The ICC's Evidence Problem


The ICC's early history indicates that more attention must be paid to the investigative practices of the Office of the Prosecutor. The judicial record to date, and the increasing dissatisfaction amongst affected communities with the Court's work, belies the desirability of the ‘light-touch,’ low-cost approach to investigations that has hitherto been championed. Rather than positioning the ICC as a remote site of justice, the Office must locate its investigative work more thoroughly on the territories in which it is engaged. The composition of its staff has also been insufficiently reflective of the countries under investigation and its relationships with individuals and institutions on the ground poorly managed. Despite relying heavily on the knowledge that these local actors can bring, the OTP has too often employed a unilateral approach to evidence gathering, failing to integrate their concerns and priorities into the investigative process.

II, 23 January 2012 (confirming charges against William Ruto and Joshua Sang, but declining to confirm charges against Henry Kosgey); The Prosecutor v. Francis Kirimi Muthaura et al., Decision on the Confirmation of Charges Pursuant to Article 61(7)(a) and (b) of the Rome Statute, ICC-01/09-02/11-382-Red, P.T.Ch. II, 23 January 2012 (confirming charges against Francis Muthaura and Uhuru Kenyatta, but declining to confirm charges against Mohammed Hussein Ali). In March 2013 the Prosecutor sought, and was granted, permission to withdraw charges against Muthaura as well, on the basis that ‘serious investigative challenges, including a limited pool of potential witnesses’, led her to the conclusion that there was no longer a reasonable prospect of conviction. See The Prosecutor v. Francis Kirimi Muthaura and Uhuru Muigai Kenyatta, Prosecution Notification of Withdrawal of the Charges against Francis Kirimi Muthaura, ICC-01/09-02/11, T.Ch. V, 11 March 2013, para. 11.

7 See The Prosecutor v. Laurent Gbabgo, Decision Adjourning the Hearing on the Confirmation of Charges Pursuant to Article 61(7)(c)(i) of the Rome Statute, ICC-02/11-01/11, P.T.Ch. I, 3 June 2013. By majority, the Chamber considered that the evidence, ‘although apparently insufficient, does not appear to be so lacking in relevance and probative value’ as to leave it no choice but to decline confirmation. The Chamber adjourned the hearing and asked the Prosecutor to ‘consider providing, to the extent possible, further evidence or conducting further investigations’; see paras. 15, 44. The Ggabgo case is not the only instance in which judges have split on the proper role of the Pre-Trial Chamber during the confirmation of charges, or the appropriate standard of proof to be applied. See, e.g., Mbarushimana Decision, supra note 6, where the Chamber, also by majority, declined to confirm charges. In dissent, Judge Monageng stated: ‘[W]hat the majority sees as “insufficient evidence” I see as “triable issues” deserving of the more rigorous fact finding that only a Trial Chamber can provide.’ Ibid., para. 134.

The burden of proof during the ICC confirmation of charges stage is ‘substantial grounds to believe’. See Rome Statute of the International Criminal Court, UN Doc.A/CONF.183/9 (1998), Art. 61(7).

13 The Women's Initiatives for Gender Justice notes that gender-based crimes are the ‘most vulnerable category’ of crime at the ICC, with more than 50 per cent of such charges being dismissed before trial, attributable, in part, to ‘the Prosecution's use of open-source information and failure to investigate thoroughly’. See Legal Eye on the ICC (March 2012), available online at

14 See ICC, Regulations of the Office of the Prosecutor, ICC-BD/05-01-09, 23 April 2009, Regs. 7–9. The OTP also has an Executive Committee, which is responsible for strategic, policy, and budgetary decisions. Ibid., Reg. 4(1).

15 Although his resignation was submitted in June 2007, Brammertz had, in fact, been on leave from his position since early 2006. See ‘The Office of the Prosecutor of the ICC – 9 Years On’, FIDH, No. 579 (December 2011), 7, n. 8. Moreno Ocampo later sought to abolish the position of Deputy Prosecutor for Investigations entirely. The ASP rejected his effort to do so, however, on the basis that his successor ‘should have [the] same flexibility to decide on the composition of the Office of the Prosecutor’. See ‘Official Records of the Ninth Session of the ICC Assembly of States Parties’, ICC-ASP/9/20, Vol. 1, Part II, para. 23.

16 The ASP elected James Stewart as the Court's second Deputy Prosecutor in November 2011; Phakiso Mochochoko has led the JCCD since February 2011.

56 Mbarushimana Decision, supra note 6. The Chamber, by majority, expressed ‘concern’ over the OTP's apparent attempt to ‘keep the parameters of its case as broad and general as possible’, pleading certain charges with insufficient specificity and ‘in such vague terms,’ seemingly ‘in order to allow it to incorporate new evidence relating to other factual allegations at a later date without following the procedure [governing amendments to the charges]’, paras. 82, 110. In the case against FDLR commander Sylvestre Mudacumura, a separate Pre-Trial Chamber denied the OTP's first request for an arrest warrant for a similar ‘lack of specificity’. It later granted the warrant but excluded all of the requested counts of crimes against humanity, while noting that the application bore ‘some similarities’ to the case brought against Mbarushimana. See The Prosecutor v. Sylvestre Mudacumura, Decision on the Prosecutor's Application under Article 58, ICC-01/04-01/12, P.T.Ch. II, 13 July 2012, paras. 20, 22–29.

I, 25 August 2006, at 5. Louise Arbour, then the UN's High Commissioner for Human Rights, was also invited to submit a brief to the Court, in which she similarly called for ‘an increased visible presence of the ICC in Sudan’, insisting that it ‘is possible to conduct serious investigations of human rights during an armed conflict in general, and Darfur in particular, without putting victims at unreasonable risk’. See Situation in Darfur, Observations of the United Nations High Commissioner for Human Rights Invited in Application of Rule 103 of the Rules of Procedure and Evidence, ICC-02/05, P.T.Ch.

65 Cayley, A., ‘Witness Proofing: The Experience of a Prosecutor’, (2008) 6 Journal of International Criminal Justice 763, at 779–80. In 2010, all of the OTP charges against Bahr Idriss Abu Garda – one of only three accused in the Darfur situation to have actually appeared before the ICC – were dismissed. The Pre-Trial Chamber unanimously found that the evidence presented was ‘so scant and unreliable’ that it could not find substantial grounds to confirm the allegations. Abu Garda Decision, supra note 6.

William Samoei Ruto et al., Request by the Victims’ Representatives for Authorisation to Make a Further Written Submission on the Views and Concerns of the Victims, ICC-01/09-01/11, P.T.Ch.

70 Personal interview with member of ICC Investigations Division, July 2012.

71 The OTP's 2003 policy paper states that ‘Investigation teams will include staff members who are nationals of the countries targeted by the investigations’. This ‘inclusive strategy’ would ‘help the OTP have a better understanding of the society on which its work has the most direct impact, and will allow the team to interpret social behavior and cultural norms as the investigation unfolds’. See supra note 18, at 9.

72 Kambale, supra note 12, n. 22.

73 In contrast, both Louise Arbour and Carla del Ponte, former Prosecutors of the ICTY, hired specialists to act as political advisers in dealing with governments and key figures within the former Yugoslavia.

The Chamber expressed particular interest in testimonies that allowed it ‘to appreciate the special significance of the local customs and the function of family relationships in Ituri’, as ‘notions of hierarchy and obedience were likely to be interpreted very differently’. Ibid., para. 122.

83 Testimony from the Lubanga proceedings indicates that the term ‘intermediary’ ‘began to be used in the summer of 2004, but intermediaries only received contracts much later’. See Lubanga Judgement, supra note 10, para. 194.

95 Lubanga Judgement, supra note 10, para. 195. The Prosecutor also drew heavily on evidence gathered from confidential agreements with intermediaries in its cases against Katanga and Ngudjulo Chui, leading the Pre-Trial Chamber to similarly lament ‘the reckless investigative techniques during the first two years of the investigation into DRC’. Prosecutor v. Katanga, Decision on Article 54(3)(e) Documents Identified as Potentially Exculpatory or Otherwise Material to the Defence's Preparation for the Confirmation Hearing, ICC-01/04-01/07, P.T.Ch. I, 20 June 2008, para. 123.

96 Draft Guidelines, supra note 84, at 3. It should be noted that while many organizations (for instance, local NGOs) can also serve as intermediaries, the Guidelines only govern the ICC's relationships with individuals. In addition to the Guidelines, a draft ‘Code of Conduct for Intermediaries’ and a ‘Model Contract for Intermediaries’ have also been created (draft of April 2012; on file with author).

97 On this point, see, e.g., Baylis, E., ‘Outsourcing Investigations’, (2009) 14 UCLA Journal of International Law and Foreign Affairs 121; see also Haslam, E. and Edmunds, R., ‘Managing a New “Partnership”: “Professionalization”, Intermediaries and the International Criminal Court’, (2013) 24 Criminal Law Forum 49.

98 See, e.g., Lubanga Judgement, supra note 10, para. 184, where the Court notes that most intermediaries are ‘activists, most of whom [are] fully aware of developments within the sphere of international criminal justice and the objectives of the investigators’.
