This article discusses changing nature of the Community authority and emerging legitimacy problems in the course of the completion of the single market. It analyses the transformation of the European Community into a more bureaucratic and technocratic authority since the Single European Act, in the light of regulatory model developed by Majone. By adopting a Weberian approach, this work attempts to understand the legitimacy crises of the European Community through critical evaluations of Majone s regulatory model.
