This paper explores the contribution of the Nairobi Declaration on the Right of Women and Girls to a Remedy and Reparation to the problem of delivering justice through reparation programmes for women victims of sexual violence in conflict situations. It highlights that this civil society initiative is particularly significant because it gives voice to women and girls who are survivors of sexual violence. Placed in the context of the recent adoption by the United Nations' General Assembly of the Basic Principles and Guidelines on the Right to a Remedy and Reparation for Victims of Gross Violations of International Human Rights Law and Serious Violations of International Humanitarian Law, the Nairobi Declaration redefines reparation and guides policy-making to implement the right to reparation specifically for victims of sexual violence. The concept of reparation as a transformative and participative process put forward in the Nairobi Declaration constitutes its most innovative and inspiring contribution.
