The publication is entitled ‘Les évolutions de la protection juridictionnelle des fonctionnaires internationaux et européens /New Developments in the Legal Protection of International and European Civil Servants’. It will appear in the collection «Pratique du contentieux européen» published by Bruyland/Larcier (Brussels).The chapters in this book originated as papers presented at theconference “New Developments in the Legal Protection of Internationaland European Civil Servants” held in Luxembourg on 1-2 April 2011 and co-organised by the Committee of Staff Representatives of the Co-ordinated Organisations (CRP), the Ministry of Foreign Affairs of the Grand-Duchy of Luxembourg and the University of Luxembourg. Financial support for the conference was provided by the Fonds National de la Recherche Luxembourg (FNR), the European Co-operative Association of International Civil Servants (AMFIE),and the International Association of Retired Staff Members of the Council of Europe (AIACE). The conference sought to evaluate the quality of the legal protection provided within the United Nations and the European Union and compare it with that provided by the Co-ordinated Organisations (the Council of Europe, the Organisation for Economic Co-operation and Development, the North Atlantic Treaty Organisation, the Western European Union, the European Space Agency and the European Centre for Medium-Range Weather Forecasts). In the light of this discussion, the conference examined the extent to which the latter systems are sustainable and considered what reforms might best be undertaken. Speakers included employees of the various concerned organisations and judges from their staff tribunals, and included a number of Luxembourg-based individuals.
