After many presentations of individual judgments in recent years, time has come for a stock-taking of the general situation of the interplay between Strasbourg and Luxembourg.
This is the purpose of the short paper below. It sets out, with many case-law illustrations listed by area, the main trends characterising that interplay since 2021. These areas are: procedural rights in criminal proceedings, judicial independence, freedom of religion, the right to be forgotten, migration, the European arrest warrant, abduction of children, non bis in idem and the protection of personal data.
It is sometimes claimed that the protection of fundamental rights in Luxembourg and Strasbourg is virtually similar, any differences being negligible. This is an over-simplification of the issue. The real picture is much more differentiated, with significant consequences at domestic level, because of their impact on the precise level of protection which judges and prosecutors will apply and, ultimately, citizens will benefit from. This is indeed where the effects of this interplay are being felt on a daily basis.
The following five conclusions emerge from this paper:
- Whereas the areas of convergence are a reason for satisfaction, the areas of divergence represent a challenge for national judges and prosecutors.
- The EU legal system is autonomous, but the national judges and prosecutors are not, because they remain subject to the Convention and must apply EU law in compliance with it, which requires a comparison of the respective levels of protection.
- Consequently, in the field of fundamental rights, EU law is not the end of the story. Rather, a wholistic approach is called for, which takes into account the interplay between EU law and the Convention.
- Fundamental rights are in essence individual rights. They call for an individual test, which can be complemented but not replaced by a general test.
- As Executief van de Moslims van België shows, the last possible stop of a case as regards fundamental rights is Strasbourg and its ultimate benchmark is the Convention, as minimum standard. From this perspective, it makes little sense not to take into account from the start what is going to be the ultimate benchmark at the end anyway. The goal is not uniformity but cross-system compatibility of the case-law.
