The adage 'ignorance of the law is no excuse' is significantly inaccurate. Ignorance and mistake of law do, under certain circumstances, exclude responsibility both in national and international criminal law. This monograph updates the existing reviews of law and practice on the topic, aiming to go a step further: it takes the analysis of mistake of law as a starting point for systematic observations about international criminal law in general. First, the volume defines the contours of the defence of mistake of law in general theory of criminal law, distinguishing it from cognate defences and highlighting, most notably, its connection with superior orders. Secondly, it gives an overview of the possible approaches to the defence, offering examples from national law as terms of reference for the subsequent analysis of international criminal law. Thirdly, it surveys the relevant law and practice of international criminal tribunals, with a focus on the International Criminal Court, and it contemplates offences for which a defence of mistake of law may potentially succeed. Finally, the author tries to interpret what the rules on mistake of law applicable before international criminal tribunals imply about the purpose of punishing individuals and to the legitimacy of such punishment. Whilst the discourse on international criminal law is more and more concerned with global politics, The Defence of Mistake of Law in International Criminal Law brings back the focus on the appropriateness of imposing a guilty verdict on the individual defendant, a human being constituting the basic unit of each society.

When a perpetrator of an international crime argues in his defence that he did not realise that he had violated the law, is this a reason not to punish him? International crimes constitute serious offences and it could be argued that he who commits such an offence must know his act is punishable. After all, everyone is presumed to know the law. However, convicting someone who is mistaken about the wrongfulness of his act may be in violation of the principle ‘no punishment without guilt’. This book investigates when 'mistake of law' should be a reason to exculpate the perpetrator of an international crime. It demonstrates that the issue of 'mistake of law' goes to the heart of individual criminal responsibility and therewith contributes to the development of a more systematic approach toward the structure of international offences. Valuable for academics and practitioners in the field of International Criminal Law.

Ignorance and mistake of law tend to exclude responsibility in national and international criminal law. This monograph updates the existing reviews of law and practice on the topic and focuses on the appropriateness of imposing a guilty verdict on the individual defendant.

The Second Edition of "Defenses in Contemporary International Criminal Law" ventures farther into this uneasy territory than any previous work, offering a meticulous analysis of the case law in the post World War II Military Tribunals and the ad hoc tribunals for Rwanda and the Former Yugoslavia, with particular attention to the defenses developed, their rationales, and their origins in various municipal systems. It analyzes the defense provisions in the charters and statutes underlying these tribunals and the new International Criminal Court, while examining the first judgment in this field rendered by the Special Court for Sierra Leone, on June 20, 2007. The conceptual reach of this work includes not only the defenses recognized in the field's jurisprudence and scholarship (superior orders, duress, self-defense, insanity, necessity, mistake of law and fact, immunity of States), but also presents a strong case for the incorporation of genetic and neurobiological data into the functioning of certain defenses. Procedural mechanisms to invoke these defenses are also addressed.

This collection of cases and materials attempts for the first time to provide a compendium of the most important legal texts, relevant documents and cases, as well as explanatory commentary on the law of defence in international criminal proceedings by scholars and practitioners who have a wealth of relevant experience in the field. The book provides students in law school courses on international human rights law and ICL with the essential materials to understand the vital importance of an adequate defence in international criminal proceedings. Further, the text gives legal practitioners who may consider extending their field of practice to the international level a look at the diversity of the tasks they will encounter and prepare them for the legal culture shock inevitable at the international tribunals and courts.
