Making Aggression A Crime Under Domestic Law

This book offers a comprehensive analysis of the legal questions that arise for the legislative branch when implementing the crime of aggression into domestic law. Despite being the “supreme international crime” that gave birth to international criminal law in Nuremberg, its ICC Statute definition has been incorporated into domestic law by fewer than 20 States. The crime of aggression was also omitted in the rich debate held among German scholars in the early 2000s regarding the legislative implementation of other ICC Statute crimes. The current inability of the International Criminal Court to respond to the Russian aggression towards Ukraine invites the continuation of these academic debates without neglecting the particularities of the crime of aggression. The fundamental issues discussed in this volume include the obligation to criminalize aggression, the core wrong of the crime, the normative gaps under domestic law and the jurisdictional gaps under the ICC Statute. To facilitate the operationalization of domestic implementation, the book explores the technical options for incorporating the definition into domestic law, the geographical ambit of domestic jurisdiction—most notably universal jurisdiction—as well as legal challenges such as immunities. The book is aimed primarily at researchers and States with an interest in the domestic implementation of international criminal law but those already working in the field should also find much of interest contained within it. Dr. Annegret Hartig is Program Director of the Global Institute for the Prevention of Aggression and worked as a researcher at the University of Hamburg where she obtained her doctoral degree in international criminal law.

An analysis of the crime of aggression amendments adopted under the International Criminal Court's Statute in 2010.

Since after the Second World War, the crime of aggression is – along with genocide, crimes against humanity and war crimes – a “core crime” under international law. However, despite a formal recognition of aggression as a matter of international criminal law and the reinforcement of the international legal regulation of the use of force by States, numerous international armed conflicts occurred but no one was ever prosecuted for aggression since 1949. This book comprehensively analyses the historical development of the criminalisation of aggression, scrutinises in a detailed manner the relevant jurisprudence of the Nuremberg and Tokyo Tribunals as well as of the Nuremberg follow-up trials, and makes proposals for a more successful prosecution for aggression in the future. In identifying customary international law on the subject, the volume draws upon a wealth of applicable sources of national criminal law and puts forward a useful classification of States ́ legislative approaches towards the criminalisation of aggression at the national level. It also offers a detailed analysis of the current international legal regulation of the use of force and of the Rome Statute ́s substantive and procedural provisions pertaining to the exercise of the International Criminal Court ́s jurisdiction with respect to the crime of aggression, after 1 January 2017.

This book provides an essential and critical overview of the most significant issues concerning the domestication of international criminal law, in particular with regard to the implementation of the ICC Statute. It discusses the most recent proposals for reform of the German Code of Crimes under International Law, the "Völkerstrafgesetzbuch", 20 years after its entering into force and introduces the project for an Italian code of international crimes drafted by the Committee of experts established in 2022 by the Ministry of Justice. Following the adoption of the ICC Statute, many States, including Germany with the "Völkerstrafgesetzbuch", introduced specific legislation to incorporate international criminal law into their domestic legal systems and a considerable number of them have been investigating and prosecuting war crimes, crimes against humanity, genocide, and even aggression ever since. Twenty-five years later, however, the process is not completed as other countries, like Italy, are still working on adopting provisions on international crimes. This book opens with a broad overview of the different approaches of the domestication of international criminal law, with a specific focus on the German and the Italian systems. After an assessment of the prerequisites for the domestic implementation of international criminal law, also from a constitutional law perspective, each chapter offers an in-depth analysis of a specific issue, such as: the definition of international crimes (genocide and crimes against humanity, war crimes and aggression); the applicability of and exceptions to the general principles of domestic criminal law; the regulation of individual criminal responsibility; sanctions and sentencing; as well as procedural aspects related to immunities, jurisdiction and prosecutorial discretion. The strong academic perspective of many authors is complemented by an equally strong practitioner perspective of the others, provided by legal scholars in the highest positions in international and national judicial institutions, resulting in a well-informed and critical appraisal of the most recent developments overall in the international criminal justice system. Domesticating International Criminal Law will be of great interest to legal scholars and students, as well as practitioners with an interest in comparative and international law, international criminal law and international relations.

Principles of International Criminal Law has become one of the most influential textbooks in the field of international criminal justice. It offers a systematic and comprehensive analysis of the foundations and general principles of substantive international criminal law, including thorough discussion of its core crimes. It provides a detailed understanding of the general principles, sources, and evolution of international criminal law, demonstrating how it has developed, and how its application has changed. After establishing the general principles, the book assesses the four key international crimes as defined by the statute of the International Criminal Court: genocide, crimes against humanity, war crimes, and the crime of aggression. This new edition revises and updates work with developments in international criminal justice since 2009. It includes new material on the principle of culpability as one of the fundamental principles of international criminal law, the notion of terrorism as a crime under international law, the concept of direct participation in hostilities, the problem of so-called unlawful combatants, and the issue of targeted killings. The book retains its highly-acclaimed systematic approach and consistent methodology, making the book essential reading for both students and scholars of international criminal law, as well as for practitioners and judges working in the field.
