Breaking the Principle of Secrecy: An Examination of Judicial Dissent in the European Constitutional Courts

As “oracles of the law,” judges are trained to provide certainty and guidance within an often‐uncertain legal landscape. Nowhere is this statement truer than in the civil law tradition, where the idea of legal certainty has been prized as a “supreme value.” Despite this tradition, dissenting opinions are now quite common within most European constitutional courts. Using new data from five countries and interviews with constitutional court judges and clerks, I investigate factors that contribute to dissent on constitutional courts. Results indicate that legal and policy characteristics matter, but so do judicial backgrounds and the issues reviewed.
