Internal Market
    By stating the guarantee of the four fundamental economic liberties which are the free movement of goods, workers, services and capital, the Treaty establishing the European Economic Community in 1957 has laid down the cornerstones of the internal market, whose date of completion had been fixed by the White Paper on the internal market and the European Single Act on December 31st, 1992. Even if 20 years after the expiration of this deadline there continue to exist obstacles to the free movement rules, the internal market has nevertheless become a reality. Our research covers positive integration (the dynamics of normative approximation) and negative integration (elimination of obstacles to the free movement rules), especially in the fields of protection of the environment and human health, but also concerning more generally the role of the judge in the evolution of State intervention in the market (State aids).
