It is not disputed by the parties that nothing in the Statute or the Rules imposes the mandatory communication to the parties to the main proceedings of an amicus curiae report requested pursuant to Rules 77(C)(ii) or 91(B)(ii) of the Rules.[1] The decision to communicate an amicus curiae report filed before the trial chamber pursuant to Rules 77 or 91 of the Rules to the parties of the main proceedings therefore falls within the discretion of the trial chamber.

The Appeals Chamber therefore finds that the Trial Chamber’s decision not to communicate the Second Amicus Curiae Reports to the parties before the delivery of the Trial Judgement was unreasonable and constituted an abuse of the Trial Chamber’s discretion.[3]
