Fact is though, "undistorted competition" is not in the current objectives of the EC Treaty as set out in its Article 2. Nor is it an objective of the EU Treaty according to its Article 2. At present, ensuring competition undistorted is an "activity" of the EC listed in Article 3 §1 (g) EC. That omission has not stopped the creation of the development of substantial body of EC antitrust and state aid law.
Let's remain a little skeptical of grand objectives. After all, the Constitution of the USSR listed some pretty neat objectives too...none of which came to much in reality. What matters is the practical implementation of policy.
