The reduction in the number of parliamentarians introduced by Constitutional Law No. 1 of 2020 entailed substantial modifications to the structure of the two Chambers, thus creating the need to amend the parliamentary regulations. On July 27, 2022, the Senate Rules were reformed, not only to adjust provisions concerning quorums and numerical thresholds but also to innovate various procedures aimed at countering certain practices that in recent years have adversely affected the functioning of Parliament, including the so called parliamentary transformationism. Furthermore, the revision of the Chamber Rules is underway, seeking to reduce the phenomenon of parliamentary obstructionism. This essay aims to analyze the multiple aspects characterizing the crisis of the political representation institution emerging from the implementation of the aforementioned constitutional reform. This analysis addresses not only the reduction in representativeness but also focuses on the role the parliamentary institution is called to perform within the balances of our form of government.
