Abstract

Scholars from law, political science and sociology agree that the European Court of Justice (ECJ) interprets European law extensively and that the Court has become an “engine of integration” that, de facto, conducts integration policy. On the basis of ten landmark ECJ decisions, this paper discusses whether the politicization hypothesis can help to explain this development. The politicization hypothesis posits that ECJ judges make their decisions based on the political interests of either the countries they come from or the parties they sympathize with. The party-based variant of the hypothesis does not seem to have any explanatory power. Similarly, the country-based variant delivers no systematic explanation that could supersede alternative explanations. However, the country-based variant fits quite well with some of the cases observed. I conclude that while situationally motivated acts of politicization may actually occur at the ECJ, which does not imply that the judicial code is being totally replaced by political considerations.
