The EU Law Barometer survey assesses the impact of European Union Law on the behaviour of national peak courts across EU member states, providing insights into judicial attitudes and practices towards European integration. Law has been a cornerstone of European integration and judicial actors are central to the effective implementation and enforcement of EU rules and regulations. Supreme courts and constitutional tribunals, in particular, are pivotal to the interplay between EU Law and domestic legal orders. We ask hundreds of legal experts from Malta to Finland and Ireland to Bulgaria to report judicial practices in their own courts regarding EU Law. The EU Law Barometer is designed and administered by a team of researchers based at the Catholic University of Leuven, as part of the EUTHORITY Project
, a five-year research project funded by the European Research Council (ERC Starting Grant 638154).
