Italy’s new election bonus may miss a majority

Italy's Chamber of Deputies gave final approval to Giorgia Meloni's electoral reform on 8 October, passing it 227 votes to 164 in a secret ballot (Official Chamber vote, AGI). The law gives coalition leaders more control over who sits in Parliament. Its central promise is a seat bonus meant to deliver stable government, yet Parliament's own technical dossier shows a winner at the threshold ending one seat short of a Senate majority (Official Chamber–Senate dossier).

Meloni argues that voters will now choose a party, a coalition, a programme, a proposed prime minister and their own member of parliament (AGI). Opposition leaders Elly Schlein and Giuseppe Conte call it a rewrite of the rules to suit the government before the next election, and opposition deputies have pledged to challenge it (AP).

A bonus that can stop short

The law scraps Italy's mixed system, which combined party lists with single-seat contests. In its place comes proportional allocation of seats, topped up by a bonus for the winner (Reuters via Internazionale). To earn that bonus, a party or coalition must win at least 42% of valid votes (Official Chamber–Senate dossier).

The threshold alone is not enough. The same party or coalition must also come first in both the Chamber and the Senate, and if it fails in either, neither house awards the bonus; there is no runoff (De Standaard). The Senate condition matters because an Italian government needs the backing of both houses to take office and pass laws.

The bonus is worth 70 Chamber seats and 35 Senate seats, taken from within fixed totals of 400 and 200 (Official Chamber–Senate dossier). Parliament does not grow. Every bonus seat is one that another party would otherwise have won.

That design is where the stability promise weakens. In the dossier's simple worked example, a bloc that just reaches the threshold wins the Chamber but falls short in the Senate. It takes 202 of 400 deputies, but only 100 of 200 senators, one fewer than the 101 a majority requires (Official Chamber–Senate dossier). Real results would shift with rounding, with how votes spread across regions, and with votes for parties that win no seats.

Coalition leaders gain the most

The surer effect falls on the people who build coalitions. Votes for allied lists below the 3% threshold still count toward the coalition's 42%, even though those small lists usually win no ordinary seats (Reuters via Internazionale). That makes every minor ally worth recruiting, whatever its own chances.

Bonus seats go to a fixed list of candidates that coalition negotiators write before polling day (De Morgen). Voters cannot reorder that list. A vote for the coalition elects whoever its leaders put there, so the seats meant to secure a majority are filled by party leadership rather than by voters' preferences.

Foreign coverage has picked up a point both camps tend to skip. De Standaard quoted the political scientist Giovanni Orsina, who noted that a united opposition could win the bonus too (De Standaard). The rules reward whoever assembles the broader alliance. That reaches beyond Rome, because the winning alliance will decide who speaks for Italy when EU governments negotiate.

What still stands in the way

The law governs no election until the president formally signs and publishes it (Italian Constitution, Article 73). The Constitutional Court has not ruled on it. Its past rulings struck down a bonus with no minimum threshold and upheld a 40% threshold in 2017 (Constitutional Court, judgment 35/2017).

The opposition's promised challenge faces a procedural hurdle. Parties cannot take the law to the Court themselves. A judge hearing an actual case must first refer the question, so any review depends on a dispute reaching an Italian courtroom.

In Parliament's worked example, the bonus produces a Chamber majority but no Senate majority, so it cannot guarantee the stability Meloni promises. Its effect on candidate selection is more certain, because coalition leaders, not voters, will decide who fills the seats the bonus hands out.
