Christopher VAJDA QC is a former member of the Court of Justice of the European Union. He graduated from Cambridge University and acquired a licence spéciale en droit européen at the Université libre de Bruxelles.
In the development of the law of the European Union as well as in defining its relation to national laws, the Court of Justice of the European Union (CJEU) has been playing an important role for decades. From the principle of primacy or supremacy of the EU law to the state liability for failing to transpose EU legislation are all judicial doctrines. How do you see the role of the Luxembourg court in the solidification and development of EU law?
I would say that there are three pillars. The first is a procedural one but nonetheless highly important.
The reference of preliminary procedure is described by the CJEU as the “keystone” to the European legal order.
Courts of Member States either have the possibility or an obligation to make a reference on questions of interpretation and validity of EU measures. The CJEU is the ultimate arbiter of how provisions of EU law ought to be interpreted.
That takes me to second pillar that is the “direct effect”. This was first brought into EU law by the landmark judgment of Van Gend en Loos from the 1960s. It enables individuals whether they are corporations or natural persons to rely directly on EU law. The CJEU declared that the
EEC Treaty was different than a normal international treaty as it grants rights to individuals which they can enforce in their own domestic courts.
Furthermore, an individual now can also rely on an ever growing EU legislation and many parts of the EU Charter of Fundamental Rights.
That leads us to the third pillar that is the supremacy pillar. This principle was also established by the CJEU in a case called Flaminio Costa v ENEL. The supremacy of EU law over national law was inevitable once the Court had held that the EEC Treaty contained rules that had direct effect in the national legal order.
These three pillars gives the CJEU such an important role.
What could be the limits of this supremacy in your view? Maybe the boundaries of the Founding Treaties?
The CJEU’s jurisdiction is limited by the Treaties. However within that limit EU law is supreme over national law. If there is a wish to limit the scope of jurisdiction of the CJEU this would have to be done by Treaty amendment.
National constitutional courts or equivalent judicial forums of Member States have become increasingly involved in reviewing legislative, executive or – as the recent decision of the “Bundesverfassungsgericht” concerning the Public Sector Purchase Programme (PSPP) showed – even judicial decisions of the European Union based on the provision of the national constitutions. This constitutional review has its roots in the 1970s, but it somewhat amplified in recent decades. What role national constitutional courts play in developing EU law?
