International Legal Positivism in a Post-Modern World Cambridge: Cambridge University Press 2014 Edited together with Jean d’Aspremont ISBN: 9781107019263 International Legal Positivism in a Post-Modern World provides fresh perspectives on one of the most important and most controversial families of theoretical approaches to the study and practice of international law. The contributors include leading experts on international legal theory who analyse and criticise positivism as a conceptual framework for international law, explore its relationships with other approaches and apply it to current problems of international law. Is legal positivism relevant to the theory and practice of international law today? Have other answers to the problems of international law and the critique of positivism undermined the positivist project and its narratives? Do modern forms of positivism, inspired largely by the theoretically sophisticated jurisprudential concepts associated with Hans Kelsen and H.L.A. Hart, remain of any relevance for the international lawyer in this 'post-modern' age? The authors provide a wide variety of views and a stimulating debate about this family of approaches. |

Uncertainty in International Law: A Kelsenian Perspective Abingdon: Routledge 2010 ISBN 9780415577847 Re-engaging with the Pure Theory of Law developed by Hans Kelsen and the other members of the Viennese School of Jurisprudence, this book looks at the causes and manifestations of uncertainty in international law. It considers both epistemological uncertainty as to whether we can accurately perceive norms in international law, and ontological problems which occur inter alia where two or more norms conflict. The book looks at these issues of uncertainty in relation to the foundational doctrines of public international law, including the law of self-defence under the United Nations Charter, customary international law, and the interpretation of treaties. |
