On the 9 January 2020, Giuseppe Brescia, President of the lower house's Constitutional Affairs Committee, submitted bill AC 2329 (nicknamed Germanicum) that would replace Rosatellum with a system based on proportional representation. The bill would abolish single member constituencies, end the use of joint lists and increase the threshold from three to five percent nationally, while creating the 'right of tribune' where if a party did not reach the national threshold they could gain representation if they earned a quotient in at least three constituencies in two regions in the Chamber and in the Senate the party would need to receive a quotient in a constituency. Seats in the Chamber would firstly be apportioned on national results then subsequently into multimember constituencies, while in the Senate the process is similar but seats are first apportioned regionally, with both Houses using the Imperiali quota.[14][15][16]
