Abstract : The position of victims on international criminal scene has considerably progressed since the first international militaries tribunals were created in 1945. Even if the victims don't properly have the status of « parties » in international criminal trial, their participation in trial is henceforth a guarantee, with substantial rights. The scale of these rights, at different steps of the procedure, clarifies the way the international criminal judge interpreted the proportional dispositions of international positive laws. The role of victims is more, at the first time, to « confirm » international « public action » than exercise themselves this action to establish accused guilty or not. Their role is finally reinforced during the presentation of civil claims, by supplementary way of intervention, and more widely in search of full satisfaction. At that moment, victims become real « civil parties » with full international juridical capacity to claim their right. So, because of their actions, the victims appear in a “double” posture, vindicatory (repression) and repairing (compensation). The targeted and achieved aim was to show today what was the place of the victims in front of the international penal jurisdictions.
