Rewarding judicial independence: Evidence from the Italian Constitutional Court

摘要

We use data about the Italian Constitutional Court (1956-2006) to verify an implication of the "revisionist" explanation of judicial independence related to judicial appointments, namely that elected politicians reward more independent justices with appointments to politically controlled posts after their Court tenure expires. In this respect, the Court tenure serves as a screening device for politicians to ascertain the justices' personal independence. The empirical strategy is two-step. First, we estimate a logit fixed-effect model to evaluate the personal degree of independence for each justice reporter. This "justice-effect" is based on the proneness of a justice to declare the constitutional illegitimacy of a law controlling for the environmental conditional phenomena. Second, we verify to what extent this degree of independence affects the probability of obtaining a politically controlled post after the end of the mandate at the Court. Our results, obtained by a variety of estimators to check their robustness, strongly support the revisionist view. (C) 2015 Elsevier Inc. All rights reserved.
