This paper analyzes the criminal responsibility at the Special Court for Sierra Leone on the basis of the revision of two cases. On one hand, the first international condemnation for sexual slavery and forced marriage against the most responsible members of the Revolutionary United Front, a nonstate armed group, even after the Peace Agreement that granted full amnesty and ended the conflict in the African country. On the other hand, the judgment against the former President of Liberia, Charles Taylor, who was convicted for aiding, abetting and planning the crimes committed by rebel groups in Sierra Leone, despite enjoying immunity.
