This book seeks to understand how and why we should hold leaders responsible for the collective mass atrocities that are committed in times of conflict. It attempts to untangle the debates on modes of liability in international criminal law (ICL) that have become truly complex over the last twenty years, and to provide a way to identify the most appropriate model for leadership liability. A unique comparative theory of ICL is offered, which clarifies the way in which ICL develops as a patchwork of different domestic criminal law notions. This theory forms the basis for the comparison of some influential domestic criminal law systems, with a view to understanding the policy and cultural reasons for their differences. There is a particular focus on the background of the German law which has influenced the International Criminal Court so much recently. This helps to understand, and seek a solution to, the current impasses in the debates on which model of liability should be applied. An entire chapter of the book is devoted to considering why leaders should be held responsible for crimes committed by their subordinates, from legal, moral and pragmatic perspectives. The moral responsibility of leaders is translated into criminal liability, and the different domestic models of liability are translated to the international context, in such a way as to appeal to advanced students of ICL, academics, and practitioners who want to understand the complexities of leadership liability in international criminal law today and identify the best way to approach it.

She holds a Ph.D. in Law from the University of Amsterdam, The Netherlands.

This book delves into legal and ethical concerns over the increased weaponization of outer space and the potential for space-based conflict in the very near future. Unique to this collection is the emphasis on questions of ethical conduct and legal standards applicable to military uses of outer space. No other existing publication takes this perspective, nor includes such a range of interdisciplinary expertise. The essays included in this volume explore the moral and legal issues of space security in four sections. Part I provides a general legal framework for the law of war and peace in space. Part II tackles ethical issues. Part III looks at specific threats to space security. Part IV proposes possible legal and diplomatic solutions. With an expert author team from North American and Europe, the volume brings together academics, military lawyers, military space operators, aerospace industry representatives, diplomats, and national security and policy experts. The experience of this team provides a collection unmatched in any academic publication broaching even some of these issues and will be required reading for anyone interested in war and peace in outer space.
