When thinking about the influence of European law on compulsory health insurance, the first reflex is to evoke the strong permeation of competition law at the European level and to question its impact on the freedom of States with regard to the implementation and development of compulsory health insurance. However, it is much less the Anglo-Saxon influence currently violating the govern-ing principles of compulsory health insurance, and more generally social security, than it is the right derived from the free movement of workers, for which France is largely responsible.
