The Czech Constitution of 1992, associated with the revolutionary fervour of the 1989 Velvet Revolution, attempted to annihilate the Communist, totalitarian heritage. According to the judgments of the Constitutional Court (CCC), this meant that the rule of law in a constitutional state has not only a formal but also a substantive side, expressing the fundamental, inviolable values of a democratic society.
There was a break from an approach that had seen the judiciary as a submissive and unthinking instrument of enforcement. In relation to EU law, several measures have been subject to constitutional challenges, including domestic acts implementing the European Arrest Warrant, the Data Retention Directive, and EU sugar quotas.
The Czech Constitutional Court, which has a strong position, has underlined its EU-friendly approach. At the same time, for exceptional, flagrant cases, the CCC has retained the constitutional limits based on the democratic, rule-of-law-based state (unamendable provision under Art. 9(2) of the Constitution) and the protection of fundamental rights.
Notably, in Landtová, the CCC declared an ECJ judgment ultra vires. In general, the reasoning of the CCC often follows that of the German Constitutional Court.
In the practice of the ordinary courts, it emerges from the report that the Czech courts have adopted a rights-protective approach and carry out judicial review, including in European Arrest Warrant cases and other mutual recognition cases. The EU amendments in the Constitution are considered brief but sufficient.
