11. […] While the Practice Direction does not specifically provide for the possibility for an accused in a joint trial to file submissions in appeal proceedings initiated by his co-accused, this may be allowed in the circumstances of a given case, particularly where such accused has a specific interest in the matter and where considering such filing as admissible would be in the interests of justice and would not be prejudicial to the other parties.[1]

14. The Appeals Chamber held that to grant an accused, who has not obtained the required certification the standing to challenge a Trial Chamber decision on appeal in his response to an appeal filed by a co-accused would open the interlocutory appeal process to abuse. Where certification in accordance with Rules 73 (B) and (C) of the Rules is required, parties must obtain such certification if they intend to appeal a decision. Consequently, the Appeals Chamber considers that it will only take into consideration those arguments made by Mr. Ndayambaje and Mr. Ntahobali that are legitimately made in response to the certified appeal of the Appellant.
