The EU has only limited competence to regulate national health-care systems but recent developments have shown that health care is not immune from the effects of EU law. As Member States have increasingly experimented with new forms of funding and the delivery of health-care and social welfare services, health-care issues have not escaped scrutiny from the EU internal market and from competition and procurement rules. The market-oriented EU rules now affect these national experiments as patients and health-care providers turn to EU law to assert certain rights. The recent debates on the (draft) Directive on Patients Rights further underline the importance, but also the difficulty (and controversy), of allowing EU law to regulate health care. The topicality of the range of issues related to health care and EU law was addressed, in October 2009, at a conference held in Nijmegen, The Netherlands. The present volume contains inter alia the proceedings of this conference and invited essays. This volume follows the publication of The Changing Legal Framework for Services of General Interest in Europe. Between Competition and Solidarity (Krajewski M et al (eds) (2009) T.M.C. Asser Press, The Hague) and launches a new series: Legal Issues of Services of General Interest. The aim of the series is to sketch the framework for services of general interest in the EU and to explore the issues raised by developments related to these services. The book is compulsory reading for everyone who is engaged in issues relating to health care and EU law.
