Der Europ?ische Gerichtshof als Motor der Integration: Eine akteursbezogene Erkl?rung

For nearly five decades, the European Court of Justice (ECJ) has developed a decisively pro-European case law and has become the ??engine of integration??. Institutional explanations shed light on the Court??s room for manoevre. They have to be complemented by actor-centered explanations that shed light on the judges?? motives of action. The explanation offered by the following paper is unfolded in two steps. In the first one, the article describes idiosyncrasies of the European law discourse that already shaped the judges before they were appointed. The analysis of the idiosyncrasies corresponds to a scepticism towards the idea of national sovereignty, a belief in the necessity of creative and idealist, law-augmenting judges and a dominance of output-oriented legitimization strategies. In a second step, the article shows that in the sociological sense the ECJ judges constitute a group. While the individual judges share an understanding of the aims and functions of European law, the group develops its own identity and grants status to those who perform successful actions with respect to the common integration agenda. This explanation is more realistic than ??rational choice?? explanations which point to the direct and personal benefits that judges derive from their pro-European case law.
