Dalla «riserva di sovranità» alla «riserva» della Corte costituzionale? Riflessioni sulla tornata referendaria del 2025

This study analyses the last rounds of Italian referendum from the perspective of the Constitutional Court’s decisions on their admissibility. The essay focuses on the inadmissibility decision on the referendum on differentiated autonomy and the five admissibility rulings on the referendum on work and citizenship. In particular, it is the no. 10/2025 ruling on differentiated autonomy that creates a few problems of constitutional correctness, such as: the declaration of inadmissibility of a total referendum, the overlap between homogeneity check and the Central Office’s judgment on the validity of the law, and the strong influence on the decision’s outcome of the earlier no. 192/2024 ruling. Based on this analysis, it is argued that one can no longer merely speak of an admissibility that has become a judgment of constitutionality, but that the referendum is, by now, under the full «reservation» of the Constitutional Court.
