Much of the recent scholarly writings and debates on amnesty have revolved around its lawfulness, when granted in respect of the most serious crimes under international law committed in the context of civil armed conflicts. The inconclusiveness of international law on this issue - with positive international law and opinio juris calling for criminal prosecution, and State's practice favouring practical political solutions - does nothing more than deepen the confusion already affecting the international legality of national amnesties. Building on emerging trends in State's practice, this book attempts to clarify the question of the legality of national amnesties for crimes against humanity by suggesting a compromised legal framework within which amnesty and accountability can both be accommodated.
