Abstract

At the heart of the European Union legal order lie values directed collectively to the idea of European integration. As a body with significant governmental and lawmaking powers, the Union also presents itself as an institution based upon the rule of law. The Union ‘constitution’ therefore expresses both regulatory powers direct­ed towards European integration as well as rule of law principles whose scope of application is limited by the terms of the Treaties. In this article I consider how this distinctive amalgam of values operates as a constitution for the European Union, by comparison with domestic constitutional values within the Member States. I also consider how Union constitutional demands condition and inform the legal practices of the Court of Justice. Here I identify the interpretive effects of superior Union laws –‍ the core Treaty objectives as well as rule of law principles found within the General Principles ‍– as of particular significance in developing the legal influences of the entire Union project of integration.
