The Appeals Chamber reiterated that Rule 66(B) applies to appellate proceedings and that, consequently, the Prosecution, on request of the Defence, has to permit the inspection of any material which is capable of being admitted on appeal or which may lead to the discovery of material which is capable of being admitted on appeal. It also noted that purely inculpatory material is not necessarily immaterial for the preparation of the Defence.

9. La Chambre d’appel rappelle que l’article 66(B) du Règlement s’applique en appel à la condition que les éléments de preuve visés par la demande d’examen de la Défense aient été indisponibles lors du procès[1]. L’applicabilité de l’article 66(B) à la procédure d’appel implique que le Procureur doive permettre à la Défense de prendre connaissance des éléments qui « soit sont nécessaires à la préparation de la défense de l’accusé, soit seront utilisés par le Procureur comme moyens de preuve au procès, soit ont été obtenus de l’accusé ou lui appartiennent »[2]. A cet égard, la Chambre d’appel rappelle que les pièces exclusivement à charge ne sont pas nécessairement inutiles à la préparation de la défense de l’accusé et que le Procureur devrait déterminer si « les questions auxquelles se rapportent les pièces en question sont […] l’objet d’un motif d’appel » ou si « les pièces en question peuvent raisonnablement permettre à la Défense de faire de nouvelles investigations et donner lieu à la découverte de moyens supplémentaires admissibles en vertu de l’article 115 du Règlement »[3]. Par conséquent, il appartient au Procureur de permettre à l’Appelant de prendre connaissance de « tout élément susceptible d’être admis en appel ou qui pourrait donner lieu à la découverte d’éléments de preuve susceptibles de l’être »[4].

At para. 16, the Appeals Chamber sets clearly the criteria of determination of the documents which are material to the preparation of the defence:

16. In addition, while the parties do not refer to Rule 66(B) of the Rules, the Appeals Chamber notes that the Appellant’s request appears to fall under this provision since he is seeking access to documents that would be material to the preparation of his defence with respect to the cross-examination of Witness EB at the evidentiary hearing or might be intended for use by the Prosecution as evidence on that occasion. It has already been clarified that Rule 66(B) applies to appellate proceedings and that, consequently, the Prosecution, on request of the Defence, “has to permit the inspection of any material which is capable of being admitted on appeal or which may lead to the discovery of material which is capable of being admitted on appeal”.[1] In this respect, the Appeals Chamber recalls that “purely inculpatory material is not necessarily immaterial for the preparation of the Defence” and that the Prosecution should instead consider “(a) whether the issues to which the material relates are subject of a ground of appeal” or “(b) whether the material could reasonably lead to further investigation by the Defence and the discovery of additional evidence admissible under Rule 115 of the Rules”.[2] Therefore, the Appeals Chamber proprio motu directs the Prosecution to apply the above-mentioned criteria in order to determine whether it is in possession of any documents that are material to the preparation of the Defence, with the exception of Rule 70 material as discussed above, and then return, if necessary, to the Appeals Chamber for permission to withhold any information provided by these sources under Rule 66(C) of the Rules.
