This document summarizes research on the knowledge, experiences, and attitudes of lower court judges in Germany and the Netherlands regarding European Union law. It finds that while judges are generally supportive of EU integration, they consider their knowledge of EU law to be lower than their knowledge of national law. Judges report that EU law has a limited impact in most cases, but plays a more routine role for those dealing with highly Europeanized legal fields. The document recommends further training and guidance focused on specific EU law issues to help judges better recognize and address any relevant EU law questions in their cases.
