This book describes the expansion of EU power in health care and public health and analyses the implications of this expansion on EU health values and rights. The main conclusion of the book is that the EU is de facto balancing fundamental rights and values relating to health, implicitly taking on obligations for safeguarding fundamental rights in the field of health and affecting individuals’ rights sometimes without an explicit legal competence to do so. This brings to light instances where EU health policy has implications for fundamental rights and values without the possibility to challenge the exercise of power of the EU in human health. This begs the question of whether subsidiarity is still the most relevant legal principle for the division of powers and tasks among the Member States, particularly when EU policy and law involves the politically sensitive areas of health care and public health. This question draws out the parameter for continuing the debate on the role of the European Union in promoting its own values and the wellbeing of its peoples, in light of its ever-growing role in human health issues.
