Burden and Standard of Proof in Defence Challenges to the Jurisdiction of the International Criminal Court

Published online by Cambridge University Press:  27 January 2015

Abstract

The jurisdiction of the International Criminal Court has remained largely uncontested during the first 10 years of its operation. Today, the jurisdictional cooling-off period seems to have run its course. The Prosecutor has opened the first Article 15 investigations and prosecutions in Kenya. The defence has been active in challenging the jurisdiction of the Court. Judges at the pre-trial stage have taken a more inquisitive approach to jurisdictional assessments. This awakening has led to the identification of novel legal issues. One of them is the applicable burden and standard of proof for defence challenges to jurisdiction. So far, this issue has been addressed largely through interpretation of the Statute. The Court's first decisions seem to fluctuate significantly on this point. From pronouncements accepting that such burden and standard do exist and seeking to articulate them, to rulings implying that they do not exist altogether, the Court's case law reveals a measure of inconsistency and a lack of reasoning. This article seeks to expose the different positions assumed on the matter, typically as a result of the judges’ efforts to balance procedural efficiency and fair trial considerations. In doing so, we will reflect critically on the causes and effects of the current state of the law and propose a reorientation of the case law through the use of other relevant international jurisprudence.

55 The Pre-Trial Chamber's examination of jurisdiction under Art. 15 in Kenya requires more elaborate examination. The early stage of the process did not prevent the judges from engaging in a rigorous assessment of jurisdiction. The questionable equation of the ‘appears to fall’ standard in Art. 15(4) with ‘a crime … within the jurisdiction’ in Art. 53(1)(a) seems to be largely responsible for this outcome.

68 Ibid. The moment when the trial commences is not clearly defined in Art. 19(4) of the Rome Statute. In the Katanga admissibility decision, the Court considered this to be the moment when the Trial Chamber is constituted, whereas one year later in the Bemba decision, the Trial Chamber considered this moment to arise when the evidence is called and the counsel addresses the merits of the case. Prosecutor v. Germain Katanga and Mathieu Ngudjolo Chui (Reasons for the Oral Decision on the Motion Challenging the Admissibility of the Case (Article 19 of the Statute)), ICC-01/04-01/07, 16 June 2009, para. 49.

118 In the Extraordinary Review decision, the Appeals Chamber considered that 21 examples of domestic legislation did not sufficiently prove the contention of the Prosecutor that there is a general principle of law allowing the Prosecutor to file an appeal against a refusal of leave to appeal. The Chamber endorsed a very high, universal adoption standard. Situation in Dem. Rep. Congo, Judgment on the Prosecutor's Application for Extraordinary Review of Pre-Trial Chamber I's 31 March 2006 Decision Denying Leave to Appeal, ICC-01/04, 13 July 2006, paras. 27, 31–32. Moreover, in its decision on witness proofing, the Trial Chamber rejected the argument of the Prosecutor that substantive preparation of witnesses before trial is allowed as a matter of a general principle of law. The Trial Chamber stated that this conclusion was warranted, because the Prosecutor had failed to provide support for this contention from Romano-Germanic systems and relied solely on common law jurisdictions.
