To what extent is a constitutional court an integral actor in the system of checks and balances? In order to answer this question, we present the novel Constitutional Court Database (CCDB) which links (1) 2006 Senate decisions (2) combining 3284 different proceedings referred to the German Federal Constitutional Court (GFCC) between 1972 to 2010 to (3) information from the political environment and (4) to societal developments. The relational structure of the database is well suited to connect information across the four different layers in flexible and dynamic ways. This allows to take different perspectives on the GFCC as a legal, political or societal actor and as a representative case of a highest court with constitutional review powers.
In order to outline the usability of the database, we present a “how-to” paper. Designing the relational, multi-layered database a number of theoretical, conceptual and computational challenges had to be overcome. Presenting those challenges and details on how to compute the database will help scholars of political science and methodologists alike. Moreover, connecting the judicial and legislative domain to address the question to what extent legislative length is a predictor of a law’s referral to a constitutional court, we present a use-case to outline the power of the database. The flexible CCDB extents on existing static databases, such as the Supreme Court database. The aim of the novel data-structure is to provide a tool useful to legal scholar, scholars of political science, journalists and the public.
