On 24 to 27 April 2013, a panel of nine experts with extensive experience in processes involving a large number of victims met in The Hague to consider challenges that the International Criminal Court (ICC) is currently facing in giving effect to the rights of victims to participate in the Court’s proceedings. The meeting was organised by Amnesty International and REDRESS, in consultation with the panel members and the ICC. This report, which is based on the panel’s review of the current participation system and detailed consultations with the ICC and NGOs, sets out its findings, including principles and recommendations aimed at strengthening the participation system and ensuring that participation is effective and meaningful for victims.
