Complicity and the Law of State Responsibility

'It was high time for an academic treatment of this fundamental issue for the international legal order. A decisive contribution in this regard has now been made by Helmut Philipp Aust ... The history, content, structure and international legal context of the norm are analysed by the author in a comprehensive and precise manner. This is also true for the conflicts between law, morals and politics which impact upon the development and interpretation of the rule on complicity. Aust takes the position of a carefully balancing pragmatist who clearly identifies international legal deficits, but refrains from moral rigour. In general, the book excels in its high relevance to practice.' Translated from the Frankfurter Allgemeine Zeitung
'... a structured and insightful analysis of this area of international law and ... a timely examination of the subject ... Due to its breadth, depth of coverage, and systematic analysis, Aust's work will likely become regarded as an important treatise on state complicity.' Nathaniel Yong-Ern Khng, Yale Journal of International Law
'... excellent ... Aust provides a comprehensive examination of state practice as it relates to complicity, along with a thought-provoking theoretical discussion of where the concept might fit within the current and future development of international law.' Michael Byers, European Journal of International Law
'... essential for understanding the notion of complicity ... The discussions in the book rest on an impressive range of material and on rigorous reasoning, the whole being written in a direct and engaging style. Reading of this book is to be recommended to everyone interested in the law of international responsibility.' Olivier Corten, translated from Revue Belge de Droit International
