Differentiated autonomy act for ordinary-statute regions (Calderoli act, 2024)

Bill presented to the Senate by the government (S. 615)[2]

Examination begins in the Senate Constitutional Affairs Committee[2][5]

Senate approves the bill at first reading[2][5]

Final approval by the Chamber of Deputies[2][5]

Entry into force (published in the Gazzetta Ufficiale on 28 June 2024)[1]

Veneto, Piedmont, Liguria and Lombardy have requested negotiations[6][5]

The minister informs the Council of Ministers that the four regions’ requests have been sent to the government. Negotiations opened on 3 October 2024.

Constitutional Court judgment no. 192/2024: law upheld as a whole, several provisions struck down[3]

On appeals by Apulia, Tuscany, Campania and Sardinia (Veneto, Piedmont and Lombardy intervened in defence of the law), the Court rejects the challenge to the law as a whole but rules that article 116(3) only allows the transfer of specific functions, on a reasoned justification under the subsidiarity principle, not of whole matters. It strikes down the delegation to the government to set the LEP, their updating by prime-ministerial decree, and the optional nature of the differentiated regions’ contribution to public-finance targets. Filed on 3 December 2024. The Court adds that Parliament may amend the agreements; substantial changes require renegotiation with the region.

In force as amended by Constitutional Court judgment no. 192/2024[1][3]

Partially struck down: transfers limited to specific functions justified by subsidiarity; the delegation and procedures for setting essential levels of services (LEP) annulled. Parliament has not amended the text since.

Court of Cassation declares the total-repeal referendum request lawful[4][5]

Request backed by 500,000 voters and by the regional councils of Campania, Emilia-Romagna, Apulia, Tuscany and Sardinia; the question was reworded to target the law « as resulting from » judgment no. 192/2024. The partial-repeal request was declared non-compliant.

Constitutional Court judgment no. 10/2025: repeal referendum inadmissible[4]

After judgment no. 192/2024 left only a « minimal content » of the law, the Court finds the question unclear as to its object and purpose: the vote would turn into a choice for or against differentiated regionalism itself, i.e. on article 116(3) of the Constitution, which can only be changed by constitutional revision. Filed on 7 February 2025.

Council of Ministers approves a new bill delegating the setting of the LEP[7][5]

33 articles with criteria specific to each matter, meant to apply the corrections required by judgment no. 192/2024; legislative decrees within nine months of entry into force, health excluded. Sent to the Senate on 11 August 2025 (A.S. 1623).

Preliminary agreements signed with Veneto, Lombardy, Piedmont and Liguria[5]

Parliamentary Budget Office hearing on the LEP delegation bill[10]

Before the Senate Constitutional Affairs Committee, the UPB finds the bill hard to implement within the set deadlines: nine months looks very tight given the number of functions and the need to quantify standard costs at the same time.

Council of Ministers approves the preliminary agreement schemes with the four regions[8][5]

Two schemes per region: civil protection, professions and supplementary pensions on one side; health protection and public-finance coordination on the other. The Unified Conference gave its opinion on 2 April 2026.

Senate (16 July) and Chamber (21-22 July) adopt their guidance acts on the schemes[5]

The four regional councils approve the final agreements[5]

Veneto on 3 September, Liguria on 9 September, Lombardy on 10 September and Piedmont on 22 September 2026.

Council of Ministers approves the final agreements and four bills to enact them[9]

Bills tabled in the Chamber of Deputies (A.C. 3161 to 3164), as bills linked to the budget[11][12][13][14]

The Chamber sets deadlines for the floor vote on the four bills[15]

Adopted by an unrecorded electronic vote over the objections of the PD, M5S, AVS and Azione, which questioned the use of the budget-linked fast-track procedure for laws requiring an absolute majority under article 116(3).

Chamber Constitutional Affairs Committee examining the four bills[5][14]

The LEP delegation bill (A.S. 1623) is still before the Senate.
