Justice Samuel Alito laughs at Prince Harry's attack on Supreme Court's Roe v. Wade decision

Supreme Court Justice Samuel Alito spoke out against foreign leaders who criticized the court’s decision to overturn Roe v. Wade, joking in a previously unreported speech he was hurt by the Duke of Sussex’s remarks the most.

One of the conservative judges on the high court, Alito brushed off foreign critics of the abortion ruling at a June 21 speech at a conference on religious liberty in Rome hosted by the University of Notre Dame Law School – his first public comments since the decision.

"I had the honor this term of writing I think the only Supreme Court decision in the history of that institution that has been lambasted by a whole string of foreign leaders who felt perfectly fine commenting on American law," Alito said in the speech.

"One of these was former Prime Minister Boris Johnson, but he paid the price," Alito continued, joking about the troubled British leader’s recent resignation.

“Others are still in office, [French] President [Emmanuel] Macron and [Canadian] PM [Justin] Trudeau are two.”

The justice than blasted Prince Harry, who appeared to refer to the decision in a July 18 speech at the United Nations, where he cited both the war in Ukraine and the “rolling back of constitutional rights” in the U.S. as “a global assault on democracy and freedom.”

"But what really wounded me, what really wounded me, was when the Duke of Sussex addressed the United Nations and seemed to compare the decision whose name may not be spoken with the Russian attack on Ukraine," Alito continued sarcastically, prompting laughs from the audience.

Alito was nominated to the court by President George W. Bush in 2005 and has served since January 31, 2006. He is considered one of the most conservative justices on the Supreme Court.

Harry was invited to speak at the UN event honoring anti-apartheid champion Nelson Mandela. He spoke for about fifteen minutes about his mother, Princess Diana’s, relationship with Mandela along with topics of the day like climate change, the war in Ukraine and the Supreme Court decision.

The speech drew criticism for its political nature and how a British royal was commemorating an activist from a former colony.

A South African newspaper went as far to mock Harry’s selection, sneering that the prince “embodies, almost perfectly, everything Mandela stood for.”

“He's in exile. Just like [Mandela],” wrote The Sunday Times editor-at-large Aspasia Karras, referring to the Duke and Duchess of Sussex’s disagreements with the more traditional royal family.
