I sistemi elettorali delle Regioni a statuto ordinario dopo la riforma del 1999: vincoli, continuità, innovazioni

The article examines the evolution of electoral systems in Italy’s ordinary-statute regions following the 1999 constitutional reform, reconstructing the constraints imposed on regional autonomy by national legislation and Constitutional Court case law. A comparison of the systems currently in force reveals a strong convergence around the model derived from the Tatarella Law, based on the direct election of regional presidents and proportional systems adjusted through majority bonuses. This convergence does not, however, preclude significant differences in the allocation of majority bonuses, seat-allocation formulas, electoral thresholds, constituency structures, safeguards for territorial representation, and voting procedures.
