With a Foreword by Jaap de Zwaan

On 1 May 2004, ten countries joined the European Union as Member States. In that same year, five other countries (Bulgaria, Croatia, Romania, Serbia and Montenegro, and Turkey) had or received (pre-)candidate country status. EU accession requires a great number of adaptations in the laws and policies of a country. In order to analyse the impact of these developments and support the countries concerned, the T.M.C. Asser Institute in The Hague initiated a project originally entitled ‘The impact of EU accession for the acceding Member States and (pre-)candidate countries’. The project, which was approved by the Dutch Ministry of Foreign Affairs and financed under the Ministry’s Matra Programme, started at the beginning of 2003 and concluded during the Dutch EU presidency with a final conference in The Hague in October 2004.

In preparation for this conference, a group of distinguished experts from the fifteen participating countries analysed, according to identical guidelines, the impact of accession on the organization of their national governments, parliaments and judiciaries, as well as on their national constitutions. Their research activities resulted in fifteen country reports offering a multitude of interesting insights, views and experiences. In 2005, the reports were updated by the authors and editors of this book, so that they could be made available to the wider public. As a comparative study of fifteen countries, it is an excellent guide for the preparation of the national legal orders for EU accession, for briefing and training civil servants, judges, practitioners, officials of international organizations and academics, and for post-graduate students.

The multi-country research project was carried out by, and under the guidance of, Alfred E. Kellermann, T.M.C. Asser Institute, Jenoe Czuczai, European Law Academy Budapest, Steven Blockmans, T.M.C. Asser Institute, and Anneli Albi, University of Kent. They also formed the editing team of the book, which was further complemented by Wybe Th. Douma, T.M.C. Asser Institute.
