This book fills a major gap in the scholarly literature concerning international criminal law, comparative criminal law, and human rights law. The principle of legality (non-retroactivity of crimes and punishments and related doctrines) is fundamental to criminal law and human rights law. Yet this is the first book-length study of the status of legality in international law - in international criminal law, international human rights law, and international humanitarian law. This is also the first book to survey legality/non-retroactivity in all national constitutions, developing the patterns of implementation of legality in the various legal systems (e.g., Common Law, Civil Law, Islamic Law, Asian Law) around the world. This is a necessary book for any scholar, practitioner, and library in the area of international, criminal, comparative, human rights, or international humanitarian law.

This book tackles one of the most contentious aspects of international criminal law – the modes of liability. At the heart of the discussion is the quest for balance between the accused's individual contribution and the collective nature of mass offending. The principle of legality demands that there exists a well-defined link between the crime and the person charged with it. This is so even in the context of international offending, which often implies 'several degrees of separation' between the direct perpetrator and the person who authorises the atrocity. The challenge is to construct that link without jeopardising the interests of justice. This monograph provides the first comprehensive treatment of complicity within the discipline and beyond. Extensive analysis of the pertinent statutes and jurisprudence reveals gaps in interpreting accessorial liability. Simultaneously, the study of complicity becomes a test for the general methods and purposes of international criminal law. The book exposes problems with the sources of law and demonstrates the absence of clearly defined sentencing and policy rationales, which are crucial tools in structuring judicial discretion.

The goal of this book is to minimize the misunderstandings and conflicts between International law and Islamic law. The objective is to bring peace into justice and justice into peace for the prevention of violations of human rights law, humanitarian law, international criminal law, and impunity.

This book develops a theory for the principle of legality in European criminal law. Its focus is on the legitimising and normative functions of this principle.

This book argues that accountability for extraordinary atrocity crimes should not uncritically adopt the methods and assumptions of ordinary liberal criminal law. Criminal punishment designed for common criminals is a response to mass atrocity and a device to promote justice in its aftermath. This book comes to this conclusion after reviewing the sentencing practices of international, national, and local courts and tribunals that punish atrocity perpetrators. Sentencing practices of these institutions fail to attain the goals that international criminal law ascribes to punishment, in particular retribution and deterrence. Fresh thinking is necessary to confront the collective nature of mass atrocity and the disturbing reality that individual membership in group-based killings is often not maladaptive or deviant behavior but, rather, adaptive or conformist behavior. This book turns to a modern, and adventurously pluralist, application of classical notions of cosmopolitanism to advance the frame of international criminal law to a broader construction of atrocity law and towards an interdisciplinary, contextual, and multicultural conception of justice.
