Mattarella enacts the Stabilicum, the new electoral law.

The President of the Republic, Sergio Mattarella, has promulgated the new electoral law, called "Stabilicum." The signature came on Friday evening, following the final approval in the Chamber of Deputies, which passed with 227 votes in favor and 164 against. The reform replaces the previous mixed system (Rosatellum) by introducing a predominantly proportional system with a majority bonus that is triggered for the coalition that reaches 42% of the votes, guaranteeing it up to 56.5% of the seats.

The approval has immediately reopened the debate on the date of the next general elections. While members of the Brothers of Italy have hinted at the possibility of an early vote to capitalize on their support, the leaders of the League and Forza Italia, Matteo Salvini and Antonio Tajani, have strongly reiterated their intention to complete the current legislature, which naturally expires in the autumn of 2027. The opposition parties have announced appeals to the Constitutional Court.

The discussion on electoral reform in Italy is a recurring theme, as over the last few decades the system has changed multiple times, often criticized for failing to ensure government stability. The last law in force was the so-called "Rosatellum," a mixed system. The current center-right majority, led by Giorgia Meloni, has set the goal of passing a new law, nicknamed "Stabilicum," with the declared intent of ensuring governability through a majority bonus.

The reform process culminated with the final vote in the Chamber of Deputies. The definitive text, also the result of mediation with the Quirinale, sets the threshold for obtaining the bonus that ensures a solid parliamentary majority at 42%. The promulgation by President Mattarella, a required step after parliamentary approval, marks the law's entry into force. This event, combined with polls showing the relative majority party ahead, has reignited the debate on the possibility of early elections—a hypothesis that, however, divides the ruling coalition and could be complicated by the timing of appeals to the Constitutional Court announced by the opposition.
