Samenvatting

Evaluations of EU legislation can fulfill a key role in the European policy process. They can provide the knowledge base required for political accountability towards the electorate, and form a basis for the improvement of existing legislation. This article introduces a research agenda in the realm of the ex-post evaluation of EU legislation, which comprises two research lines. The first strand comprises research into ex post legislative evaluations conducted by the European Commission. This research is innovative, because EU policy researchers so far have barely touched upon evaluation, as a final and important stage in the EU policy cycle. By assessing evaluation critically, we can ascertain to what extent the EU’s ex-post evaluation system is more than an instrument, aimed at increasing the EU’s legitimacy. The second research strand is own evaluation research, focusing on the role of European administrative networks- intergovernmental structures that have been established to improve the implementation of EU legislation by the member states. By critically evaluating the functioning and effectiveness of these networks, I hope to be able to find out whether and under what conditions these network structures are more, than the sum of their national parts.
