Italian Citizenship Ruling 2026: What the Court Decision Means for Millions With Italian Ancestry

A major legal decision in Italy has sparked global debate after the Italian Constitutional Court upheld a controversial reform affecting how people claim Italian citizenship through ancestry. The ruling confirms that Italy can place stricter limits on the long-standing citizenship-by-descent system, potentially affecting millions of people around the world who have Italian heritage. For decades, Italy allowed descendants of Italian emigrants to apply for citizenship with virtually no generational limit. However, the new ruling supports reforms introduced by the government that significantly narrow eligibility.

Background: Italy’s Citizenship by Descent (Jus Sanguinis) Italy traditionally followed the principle of “jus sanguinis”, meaning citizenship through bloodline rather than birthplace. Under this rule: Anyone who could prove Italian ancestry could potentially claim citizenship. There was no strict limit on generations, meaning even great-great grandchildren of Italian emigrants could apply. Millions of descendants of Italians living in countries such as the United States, Brazil, Argentina, and Canada were eligible. This policy helped maintain cultural ties with the Italian diaspora, but it also created a huge administrative burden for Italian consulates worldwide.

The Court Ruling Explained In March 2026, the Italian Constitutional Court rejected legal challenges to a new citizenship reform law introduced by the government. The judges ruled that the reform does not violate Italy’s constitution, allowing the government to enforce stricter eligibility requirements for citizenship applications based on ancestry. The decision effectively confirms that Italy has the authority to limit how far back a family line can go when applying for citizenship. Key Changes to Italian Citizenship Rules The new rules introduce several important changes:

Generational Limits Previously, citizenship could be claimed through any Italian ancestor, regardless of how many generations had passed. Under the new reform: Eligibility is generally limited to children or grandchildren of Italian citizens. Applicants with more distant ancestry may no longer qualify. Stronger Proof Requirements Applicants must now provide clear documentation proving the citizenship status of their parents or grandparents, including birth, marriage, and naturalization records. Reduced Consulate Backlogs Italian consulates around the world have faced massive backlogs of citizenship applications. The reform aims to reduce processing delays and focus resources on applicants with closer family ties to Italy.

Why Italy Changed the Law Italian officials argue that the old system had become difficult to manage. Several factors pushed the government to reform the law: Surging demand for EU passports Long waiting lists at consulates Applications from people with very distant Italian ancestry The government says the reform ensures citizenship remains meaningful and reflects a genuine connection to Italy Who Is Most Affected The ruling primarily affects people in countries with large Italian diaspora communities, including.United States Brazil Argentina Canada Australia

Many families in these countries trace their roots to Italian immigrants who left Europe in the late 19th and early 20th centuries. Under the new rules, descendants whose Italian ancestor is more than two generations back may find it significantly harder—or impossible to obtain Italian citizenship. What Happens to Current Applications Applicants who already submitted their citizenship requests before the reform may still be processed under earlier rules, depending on their case. However, new applications filed after the law takes effect must follow the stricter requirements established by the reform.

Legal experts say further court challenges could still occur, especially from diaspora communities. Impact on the Global Italian DiasporaItaly has one of the largest diasporas in the world. Tens of millions of people outside Italy claim Italian ancestry. The court’s ruling could reshape how Italy connects with these communities. While some argue the reform protects the value of Italian citizenship, others believe it limits opportunities for descendants who want to reconnect with their heritage

The recent ruling by the Italian Constitutional Court marks a major shift in Italy’s citizenship policy. By upholding new limits on citizenship by descent, the court has allowed the government to redefine who qualifies for an Italian passport. For millions of people worldwide with Italian roots, the decision could change long-standing expectations about gaining citizenship through ancestry. As the new rules take effect, many potential applicants will need to reconsider their eligibility and explore alternative immigration pathways.
