European Constitutional Court Network Data (OA edition)

Constitutions contain the most important rules of our political systems and Constitutional Courts are the most powerful judicial institutions of European states. They are the guardians of the Constitutions and ensure, for instance, the respect for fundamental rights.

Since the 20th century their importance is ever growing, which attracted a lot of interest from academia and beyond. Yet, despite numerous investigations, we know little about how and to what extent different Constitutional Courts cite each other. The dataset at hand informs about the number of citations per year across national European constitutional courts, the European Court of Human Rights as well as the European Court of Justice.
