The Italian Senate begins full debate on a sweeping electoral reform this week, with a final vote scheduled for September 15 that could reshape how Italians elect their government for decades. The bill, informally dubbed the "Stabilicum" by its supporters and "Melonellum" by critics, has already received approval from the Chamber of Deputies and now moves to the Senate for final consideration. It would replace the current hybrid system with a proportional model featuring a substantial majority bonus and the formal designation of a prime ministerial candidate on the ballot.
Why This Matters
• The 42% threshold: The reform grants a bonus of 70 Chamber seats and 35 Senate seats to any coalition reaching this mark—Fratelli d'Italia is pushing to lower it to 41% to make the bonus more attainable.
• Preferences return: Voters could express up to three preferences for candidates, though the lead candidate (capolista) remains blocked—meaning party leaders control the top positions.
• Runoff eliminated: The two-round system proposal has been essentially abandoned, making the first round decisive.
• Next steps: Final Senate vote expected September 15. If passed without amendments, the law becomes effective immediately. However, if new amendments are introduced in the Senate, those specific changes will be sent back to the Chamber of Deputies for approval—not a full third reading, but a targeted vote on revised text.
What's Actually in the Reform
After years of constitutional court rulings striking down previous attempts—most notably the Porcellum in 2014 and parts of the Italicum in 2017—Italy's center-right majority believes it has finally found a formula that can survive judicial scrutiny while delivering what they call "governability."
The core mechanism distributes seats proportionally, but with a critical twist: any coalition reaching the threshold automatically receives additional seats to secure a working majority. This addresses a persistent problem in Italian politics—post-electoral haggling that produces unstable governments lasting, on average, barely 18 months.
However, the threshold debate has exposed a fault line within the governing coalition. Fratelli d'Italia, Prime Minister Giorgia Meloni's party, argues that 41% is more realistic given current polling suggests neither bloc can easily clear 42%. Forza Italia, Silvio Berlusconi's party, prefers the higher threshold, with one senator reportedly summarizing their stance: "In order of preference: victory, draw, defeat."
Constitutional scholars note that the Constitutional Court's 2017 ruling on the Italicum essentially blessed a 40% threshold as constitutional, meaning 41% or 42% would likely pass legal muster. The real question is political: can anyone actually reach it?
The Anti-"Cespugli" Provision
Buried in the technical details is a measure targeting a uniquely Italian phenomenon—"cespugli" (literally "bushes"), or micro-parties that exist primarily to siphon votes and bargain for positions. Under current proposals, lists receiving under 3% of votes would be excluded from the bonus calculation, though the coalition's highest-finishing minor party below that threshold would still count.
The opposition calls this provision a cynical consolidation of power by larger parties. Supporters argue it forces political forces to consolidate rather than fragment—a calculation that favors established parties over upstart movements.
Opposition's Do-or-Die Stand
Democratic Party Secretary Elly Schlein has made stopping the bill her immediate priority, telling supporters at a recent event: "We must do everything possible to prevent this law from passing." She frames the reform as "an unacceptable appetizer for a premiership," referring to the indirect presidentialization of the system.
The opposition—spanning the PD, the Five Star Movement, Italia Viva, and the Green and Left Alliance—has filed hundreds of amendments and promises parliamentary obstructionism. They've coordinated with civic groups preparing legal challenges should the bill pass, promising to petition the Constitutional Court before the next election.
A network of constitutional lawyers, journalists, and civic associations calling itself the "Network for a Free and Equal Vote" has announced plans for mass demonstrations after September 15, aiming to create a referendum-like atmosphere against the reform.
Their core objection: the majority bonus system fundamentally distorts representation. If a coalition wins 42% of votes, they argue, awarding them guaranteed governing seats undermines the principle of equal suffrage enshrined in Article 48 of the Constitution.
What This Means for Residents
For the approximately 46 million eligible Italian voters, this reform would transform the voting experience in several practical ways.
You'll see names, not just symbols. The reintroduction of preferences means voters can express up to three choices for specific candidates within their chosen party list—though importantly, the party leader position remains unchallengeable. This marks a partial return to the system Italians used before 2005, restoring some direct selection over representatives.
The stakes of the first round increase dramatically. With the runoff provision effectively dead, vote-getting in the first round becomes decisive. Elections could feel higher-pressure, with every percentage point mattering for bonus calculations.
Your local mayor's political calculations change. The reform addresses rules about when mayors must resign to run for parliament—a lingering point of tension. Critics argue mayors-turned-candidates hold name-recognition advantages over sitting parliamentarians. The new rules attempt to level that playing field, though details remain contested.
Small parties face existential pressure. If you vote for micro-parties, understand that they may effectively disappear under the anti-cespugli provisions. The 3% threshold forces consolidation—a knowing calculation that larger blocs will absorb smaller movements or see their votes wasted.
Timeline and Realistic Expectations
The Senate's final vote on September 15 is the critical next step. If approved without amendments, the law will become effective immediately. However, if the Senate introduces new changes—particularly to the preferences system or threshold—the bill will return to the Chamber of Deputies only for a vote on those revised provisions, not for a full third reading as previously stated. This procedural nuance is crucial: the Chamber has already given its overall approval.
Government insiders insist this reform won't trigger early elections—despite speculation that Meloni might seek a fresh mandate after passage. The current legislature runs until spring 2027, and most observers expect elections between spring and autumn 2027.
Minister for Parliamentary Relations Luca Ciriani has suggested spring 2027 makes more sense than autumn, avoiding overlap with budget preparations. "Obviously, we'd need to build a shared path with the President of the Republic," he noted—a reminder that Head of State Sergio Mattarella retains dissolution power.
The Broader Context: Anti-Semitism Bill
Running parallel to electoral reform, parliament reconvenes with contentious legislation on combating anti-Semitism awaiting consideration. The bill, based on the International Holocaust Remembrance Alliance (IHRA) definition, has drawn criticism from civil liberties advocates who argue it could conflate criticism of Israeli government policy with hate speech.
Approximately 100 organizations have called a protest for September 9 outside Montecitorio, demanding "Criticizing Israel is not anti-Semitism but a constitutional right."
The Senate's Constitutional Affairs Committee approved the measure, but opposition parties divided internally on support. The bill's passage would make Italy one of several European nations codifying the IHRA framework into domestic law.
The electoral reform's fate ultimately hinges on whether the center-right can maintain unity through the amendment process. History suggests coalition discipline holds until the final vote—when individual deputies sometimes surprise with secret ballots. This time, all Senate votes will be open roll calls, eliminating the possibility of anonymous defections that doomed earlier reforms.
