A legal and historical analysis of the first modern attempts to prosecute national leaders for embarking upon aggressive war.

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.

In this new collection of essays the editors assess the legacy of the Nuremberg Trial asking whether the Trial really did have a civilising influence or if it constituted little more than institutionalised vengeance. Three essays focus particularly on the historical context and involve rich analysis of, for example, the atmospherics of the Trial itself and the attitudes of German society at the time to the conduct of the Trial. The majority of the essays deal with the contemporary legacies of the Nuremberg Trial and attempt to assess the ongoing relevance of the Judgment itself and of the principles encapsulated in it. Some essays consider the importance of the principle of individual criminal responsibility under international law and argue that the international community has to some extent failed to fulfil the promise of Nuremberg in the decades since the Trial. Other essays focus on contemporary application of aspects of the substantive law of Nuremberg - particularly the international crime of aggression, the law of military occupation and the use of the crime of conspiracy as an alternative basis of criminal responsibility. The collection also includes essays analysing the nature and operation of a number of international criminal tribunals since Nuremberg including the permanent International Criminal Court. The final grouping of essays focus on the impact of the Nuremberg Trial on Australia examining, in particular, Australia's post-World War Two war crimes trials of Japanese defendants, Australia's extensive national case law on Article 1(F) of the Refugee Convention and Australia's national implementing legislation for the Rome Statute.

The 2010 Kampala Amendments to the Rome Statute empowered the International Criminal Court to prosecute the 'supreme crime' under international law: the crime of aggression. This landmark commentary provides the first analysis of the history, theory, legal interpretation and future of the crime of aggression. As well as explaining the positions of the main actors in the negotiations, the authoritative team of leading scholars and practitioners set out exactly how countries have themselves criminalized illegal war-making in domestic law and practice. In light of the anticipated activation of the Court's jurisdiction over this crime in 2017, this work offers, over two volumes, a comprehensive legal analysis of how to understand the material and mental elements of the crime of aggression as defined at Kampala. Alongside The Travaux Préparatoires of the Crime of Aggression (Cambridge, 2011), this commentary provides the definitive resource for anyone concerned with the illegal use of force.
