31 March 2004 the EU adopted two new public procurement directives: one for the public sector (2004/18/EC) and one for utilities (2004/17/EC). The new directives aim at simplification and modernisation of the previously existing directives including adaptation to electronic purchasing techniques. On 4-5 November 2004 the Copenhagen Business School organised a European research conference on the new directives. The conference focused on a number of topics which are of particular interest within the field of procurement law in EU these years, including ECJ case law, utilities, electronic auctions, transparency requirements, competitive dialogue, framework agreements, use of social and environmental criteria, Partnering and Public Private Partnerships and concessions. This book contains contributions based on presentations given by a number of the international and Danish speakers at the conference.
