Italy’s Constitutional Court hears challenge to Italian Citizenship crackdown — ‘perfect Italian mess’ laid bare

The Constitutional Court heard a three-hour challenge in Rome over a 2025 law that restricts italian citizenship by descent, a change that challengers say severs a long-established birthright and leaves thousands in legal limbo.

What is not being told? Who stands to lose their link to the republic?

Verified facts: the case was brought by eight Venezuelan citizens of Italian descent and is supported by diaspora organisations AGIS and the Confederation of Italians Abroad. The hearing focused on an abrupt law change in 2025 that narrowed eligibility for citizenship by descent to people with a parent or grandparent born in Italy, eliminating access for great-grandchildren and more distant descendants. Citizenship by ancestry had previously been recognised for those who could demonstrate an unbroken line of descent from an Italian citizen back to 1861.

A court in Turin referred the challenge to the Constitutional Court, arguing the law change effectively stripped citizenship from people who had already acquired it by birth “without individual assessment or adequate notice. ” A lawyer in court characterised the Tajani Decree as “a perfect Italian mess. ” These are the central, documented claims before the Constitutional Court.

How the Italian Citizenship rules changed and who is affected

The legal shift imposes a stricter generational cutoff: only descendants with a parent or grandparent born in Italy now qualify under the contested rule. If the Constitutional Court finds the change unconstitutional, applications rejected under the new rule could have grounds to appeal, and pending applications might be reassessed under the previous, broader standard. Calogero Boccadutri, founder of the Boccadutri International Law Firm, stated that a favourable ruling could reopen appeals for those rejected and permit reassessment of pending cases under the earlier criteria.

If the court upholds the law, applications submitted after March 27th, 2025 will remain subject to the stricter requirements. Separate, related litigation continues: Italy’s Supreme Court of Cassation will hear a challenge on whether children of Italians who naturalised abroad automatically lost their citizenship, and a further challenge referred by the Mantua court is scheduled for a later Constitutional Court session.

Who benefits, who is implicated, and what responses have emerged?

Established actors in the diaspora have framed a policy contradiction: the diaspora group Natitaliani has pointed to an inconsistency between government efforts to promote “roots tourism” and property investment by descendants, and simultaneous restrictions on their right to citizenship. AGIS and the Confederation of Italians Abroad are backing litigants who argue the law change breaches constitutional protections.

At the judicial level, the Turin court’s referral questions whether citizens effectively lost a pre-existing legal status without individualized review. Calogero Boccadutri offered a legal pathway contingent on the Constitutional Court’s decision: a ruling finding the law unconstitutional would enable appeals and reassessments under the earlier, more permissive framework.

Not all procedural avenues are resolved. The Supreme Court of Cassation is set to consider related questions about loss of citizenship through naturalisation abroad, a matter with particular implications for applicants with ancestry in the United States. The Mantua court’s referral adds another Constitutional Court consideration later in the calendar.

Analysis: Taken together, the filings, court referrals and diaspora mobilisation reveal a policy collision between economic outreach to descendants and a legislative redefinition of who counts as an Italian. The contested measure functions as an administrative gatekeeper that narrows eligibility without individualised reassessment, raising constitutional questions about notice and retroactivity.

Accountability and next steps: The Constitutional Court’s decision will determine whether people rejected after March 27th, 2025 retain legal routes to contest denials and whether pending applications will be restored to the prior standard. The ongoing Supreme Court of Cassation and Mantua referrals mean the legal landscape will evolve through multiple high courts.

Calls for clarity and transparency are grounded in the documented filings and institutional referrals now before Italy’s highest tribunals. For millions of descendants whose claims hinge on lineage, the outcome will decide whether bureaucratic change or constitutional safeguard governs access to italian citizenship.
