This book explores the issue of leadership criminality from a new angle by comparing two highly relevant modes of responsibility. By contrasting individual criminal responsibility for ordering international crimes with indirect perpetration through an organisation, it shows the doctrinal weaknesses of the latter and outlines the much-overlooked advantages of the former. The volume analyses the development of both forms of responsibility, looking at their origins, and their reception in academia and practical use in jurisprudence. The history of indirect perpetration through an organisation (Organisationsherrschaft) is portrayed from its German academic origin, through German jurisprudence to the reception of the doctrine at the International Criminal Court. By comparing the doctrines stages of evolution, the book sheds light on the different aspects of the various models of indirect perpetration through an organisation and carves out general and fundamental criticismof it. The characteristics of ordering liability are explored in depth through an analysis of jurisprudence of the Nuremberg subsequent trials, the ad hoc tribunals and the International Criminal Court. This historic and doctrinal comparison reveals a well-defined and to-date much neglected mode of responsibility with enormous potential for the adjudication of leadership figures in the ambit of international criminal law and only one conclusion can follow from this analysis: it calls for practitioners and academics to leave the well-trodden paths of national criminal law doctrine and embrace truly international modes of liability such as the ordering of a crime. This volume in the ICJ series provides practitioners, researchers and students with a detailed account of forms of leadership liability and an innovative approach to the topics most discussed issue.
