The highest Dutch courts and the preliminary ruling procedure: Critically obedient interlocutors of the Court of Justice

Little is known about the motives of national courts to request a preliminary ruling from the Court of Justice of the EU (CJEU) or their satisfaction with and implementation of answers. This article aims to fill this empirical gap on the basis of an analysis of judgments complemented with interviews with judges of the highest courts in the Netherlands. This article shows that judges extensively use the procedure and follow its outcome almost without exception, despite some dissatisfaction. This discontent has surprisingly not affected the courts' willingness to refer in future. The findings also downplay the bureaucratic politics and judicial empowerment theses emphasising strategic motives to refer. Instead, legal‐formalist considerations and the desire to contribute to the development of EU law explain most of the references of the Dutch Supreme Court. The decision (not) to refer of the three highest administrative courts is primarily based on practical and pragmatic considerations.
