The Comparative Constitutional Compliance Database (CCCD)
The CCCD was produced within the research project Economics of Constitutional Compliance, funded by the German Research Foundation (DFG, #381589259) and the National Science Center Poland (NCN, #UMO-2016/23/G/HS4/04371). The database offers various indicators of constitutional compliance.
