Abstract

The present study was originally meant for the FIDE XXIX Congress, which provided an excellent opportunity to review how the acquis communautaire has been implemented by ordinary courts as well as the Constitutional Court of Hungary since the country’s accession to the EU. As it is widely known, national courts play a key role in enforcing rights and obligations under EU law, so that the application of EU law remains uniform in all the Member States, in compliance with the jurisprudence of the CJEU. On the other hand, national constitutional courts must take a position more frequently and emphatically on issues related to national sovereignty: in defining what comes within the scope of the EU’s legislative competence and what remains under the control of national constitutional and legislative power. The relationship between national ordinary courts, constitutional courts and the CJEU, as well as the national implementation of Luxembourg case-law may be analyzed in a variety of ways and from different perspectives. The main principles governing EU law (such as direct effect, supremacy, mutual trust) have been developed in increasing detail over the years. Since their effect and practical consequences are outstanding, in what follows, we are shall explore these issues first in the light of Hungarian case-law. In the context of the principle of mutual trust, the discussion surrounding the independence of national courts is gaining impetus. Therefore, we will also touch upon this issue in our study. Finally, as far as the issue of effective enforcement of EU law is concerned, we shall present the Hungarian experience related to the preliminary ruling procedure, which is the most important element linking the CJEU and national courts. In this respect, we approach the issue from the domestic angle, focusing primarily on how exceptions to the obligation to submit a request for preliminary ruling have been clarified on the basis of the guidelines of the Curia of Hungary and the Constitutional Court of Hungary.
