Originating in the June 1998 joint conference of the United Kingdom Association for European Law (UKAEL) and the University Association for Contemporary Studies (UACES) and edited by David O'Keeffe and Patrick Twomey,this book brings together a collection of essays that offer critical insights into the institutional and substantive changes to the European Community and Union resulting from the Treaty of Amsterdam. With a preface by Lord Slynn of Hadley, the collection includes essays based on the conference presentations of Joseph Weiler, Anthony Arnull, Alan Dashwood, Franklin Dehousse, Hans Ulrich Jessurun d'Oliveira and Laurens Jan Brinkhorst and some twenty other essays offering the reflections and criticisms of leading academics in the field as well as the unique insights of contributors working within the Community institutions.
