This book investigates the use of duress as a defence in international criminal law, specifically in cases of child soldiers. The prosecution of children for international crimes often only focuses on whether children can and should be prosecuted under international law. However, it is rarely considered what would happen to these children at the trial stage. This work offers a nuanced approach towards international prosecution and considers how children could be implicated and defended in international courts. This study will be of interest to academics and practitioners working in international criminal law, transitional justice and children’s rights.
