Abstract
In 1996, British Prime Minister John Major has bitterly noted that European Court of Justice (ECJ) should "have its wings clipped", as already back in 1996 some member states, eager to protect their sovereignty, feared the growing influence of the court. Yet, 10 years later, the response of the President of the Austrian Constitutional Court, Karl Korinek, is bitterly the opposite, an accusation of Court's lack of integration powers. Hence, in this situation of the debate, we might ask, accessing Court's past role and its modern evolution, is European court of Justice a true activist motor for European integration? On the one hand, we will discuss the role of the Court as a motor for legal integration (I). On the other hand, we will see the Court's role in political integration in EU
