Two U.S. families went to Italy's highest court Tuesday to challenge the scope of a year-old law passed by Giorgia Meloni's government limiting citizenship claims to Italian descendants removed by more than two generations.

Their lawyer, Marco Mellone, argued before the Cassation Court that the law should apply only to people born after it took effect, potentially opening a pathway to citizenship for millions of people living in the United States and parts of Latin America. Another lawyer represented Italian descendants from Venezuela.

A decision by an expanded panel, which makes the ruling binding in lower courts, is expected in the coming weeks.

A decree by the conservative government in March 2025 put the brakes on previous rules allowing anyone who could prove ancestry after Italy's formation in 1861 to seek citizenship. Italy's constitutional court last month ruled the new law is valid, but Mellone said the supreme court has the power to clarify the scope of the law.

"The families involved in this case are simply descendants ... from an Italian ancestor who emigrated in the late 19th century to the United States, like millions of other people, of other Italians," Mellone said before the hearing. "Today they are invoking their right to Italian citizenship."

Mellone's case would clarify the citizenship rights of the descendants of some 14 million Italians who emigrated between 1877 and 1914, according to Foreign Ministry statistics, and beyond.

While Mellone's case involves two families, another dozen people whose citizenship claims were stopped by the law were present outside the courthouse in solidarity.

Karen Bonadio said she hopes one day to move to Italy on the strength of her ancestry. She brought photos of her as a young girl alongside her Italian-born great-grandparents, who emigrated from Basilicata in southern Italy to upstate New York, along with their birth certificates.

"The new law says, 'all these great-grandchildren didn't know their great-grandparents.' This is from 1963, I think I was 3 1/2," she said, showing the photograph.

At least one of Mellone's cases had been rejected in lower courts before the new law, hinging partially on rulings that Italian emigrants who took on another citizenship before having children cannot pass on Italian citizenship.

Jennifer Daley's case has been working its way through the Italian bureaucracy for nearly a decade. Her grandfather, Giuseppe Dalfollo, immigrated to the U.S. in 1912 from the northern province of Trento when it was under Austro-Hungarian control. He later married an Italian woman and brought her over, and at some point became a naturalized U.S. citizen.

Daley said she always had a strong Italian identity that transcended her last name anglicized by U.S. immigration officials. She petitioned for citizenship because "it is truly a recognition of who I am, where I am from. It's so much more than citizenship. It's everything," Daley, a historian, said by phone from Salina, Kansas.

Outside the courthouse, Alexis Traino said great-grandparents on both her maternal and paternal sides had come from Italy, where she now lives, mainly in Florence.

"My entire life, I grew up knowing — and my parents always emphasized — that I was Italian. I had a very, very strong connection with Italy," said Traino, 34, who was waiting for documents from Italy and the U.S. when the law passed, blocking her case.

A federal appeals court on Wednesday refused to block the Pentagon from blacklisting artificial intelligence laboratory Anthropic in a decision that differed from the conclusions reached in another judge's ruling on the same issues.

The U.S. Court of Appeals in Washington, D.C., rejected Anthropic's request for an order that would shield the San Francisco company from the fallout stemming from a dispute over how the Pentagon could deploy its Claude chatbot in fully autonomous weapons and potential surveillance of Americans while the panel is still collecting evidence about the case.

But the setback in Washington came after Anthropic already had prevailed in separate case focused on the same issues in San Francisco federal court. In that case, a judge forced President Donald Trump's administration to remove a label tainting the company as a national security risk.

Anthropic filed the two separate lawsuits in San Francisco and the Washington appeals court last month, asserting the Trump administration was engaging in an "unlawful campaign of retaliation" because of its attempt to impose limits on how its AI technology can be deployed. The Trump administration blasted Anthropic as a liberal-leaning company trying to dictate U.S. military policy.

In the San Francisco case, U.S. District Judge Rita Lin ruled that the Trump administration had overstepped its bounds by labeling Anthropic a supply chain risk unqualified to work with military contractors and issuing other directives that could cripple a company locked in a race for AI supremacy against rivals such as ChatGPT maker Open AI and Google.

That decision prompted the Trump administration to remove the stigmatizing labels from Anthropic and take other steps clearing the way for government employees and contractors to continue using Claude and other chatbots, according to court filing made in San Francisco earlier this week.

The Supreme Court's conservative majority on Monday sounded skeptical of state laws that allow the counting of late-arriving mail ballots, a persistent target of President Donald Trump.

A ruling, likely to come by late June, that bars counting ballots arriving after Election Day would send officials scrambling in 14 states and the District of Columbia, just a few months before the 2026 midterm congressional elections to change their ballot rules.

An additional 15 states that have more forgiving deadlines for ballots from military and overseas voters also could be affected.

The legal challenge is part of Trump's broader attack on most mail balloting, which he has said breeds fraud despite strong evidence to the contrary and years of experience in numerous states. Trump has repeatedly claimed that his loss to Joe Biden in 2020 resulted from fraud even though more than 60 court decisions and his own attorney general said that argument had no merit.

While there was no explicit reference to the 2020 election, several conservative justices gave voice to some of Trump's complaints. Justice Samuel Alito wondered about the appearance of fraud in situations where "a big stash of ballots" that arrive late "radically flipped" an election.

Defending the state law, Mississippi Solicitor General Scott Stewart pointed out that the Trump administration and its allies in the case have yet to submit a single case of fraud due to late-arriving mail ballots.

The court's liberal justices indicated they would uphold state laws with post-Election Day deadlines. "The people who should decide this issue are not the courts, but Congress, the states and Congress," Justice Sonia Sotomayor said.

Forcing states to change their practices just a few months before the election risks "confusion and disenfranchisement," especially in places that have had relaxed deadlines for years, state and big-city election officials told the court in a written filing.

California, Texas, New York and Illinois are among the states with post-Election Day deadlines. Alaska, with its vast distances and often unpredictable weather, also counts late-arriving ballots.

Alaska elections officials said Monday they are preparing for the fall elections under existing law. "If a ruling requires operational changes, we will work through those in coordination with the appropriate state entities to ensure compliance and to provide clear information to voters," the Alaska Division of Elections said in a statement.

Lawyers for the Republican and Libertarian parties, as well as Trump's administration, are asking the justices to affirm an appellate ruling that struck down a Mississippi law allowing ballots to be counted if they arrive within five business days of the election and are postmarked by Election Day.
