Even if the Principaliter Proceeding constitutes one of the most important competences of the Italian Constiutional Court, none the least because of the total number of petitions, today this institution faces some difficulties. On the one side we witness a further retreat of regions from constitutional review as manifested by the limited number of petitions coming from regions, their non-intevention in many judgments, and other attempts to escape the scrutiny of the Court. On the other side, the Court's judgments on Principaliter Proceedings often are limited to a mere comparison of legal provisions which are constantly changing. This article analyzes the most recent jurisprudence in this genre (from 2014 to 2017) trying to identify possible solutions to the aforementioned problems.
