Abstract This article explores the role of Article 6(5) of Additional Protocol II to the Geneva Conventions in balancing justice and peace during transitions from armed conflict to peace. It argues that the provision, which encourages the granting of broad amnesties at the cessation of hostilities, requires a re-evaluation of the obligation to investigate, prosecute and punish under international law. By analyzing the legal context and scope of Article 6(5), as well as its application in transitional justice models such as in Colombia, the article highlights how the principle of peace can be prioritized alongside justice without undermining victims’ rights. The discussion critically addresses maximalist interpretations of justice, presenting a nuanced approach that foregrounds restorative justice and the importance of reconciliation in post-conflict societies.
