WASHINGTON — The US Supreme Court upheld on Friday a statute passed by Congress to facilitate lawsuits against Palestinian authorities by Americans killed or injured in attacks abroad as plaintiffs pursue monetary damages for violence years ago in Israel and the West Bank.

The 9-0 ruling overturned a lower court’s decision that the 2019 law, the Promoting Security and Justice for Victims of Terrorism Act, violated the rights of the Palestinian Authority and Palestine Liberation Organization to due process under the US Constitution.

Conservative Chief Justice John Roberts, who authored the ruling, said the 2019 jurisdictional law comported with due process rights enshrined in the Constitution’s Fifth Amendment.

“It is permissible for the federal government to craft a narrow jurisdictional provision that ensures, as part of a broader foreign policy agenda, that Americans injured or killed by acts of terror have an adequate forum in which to vindicate their right” to compensation under a federal law known as the Antiterrorism Act of 1990, Roberts wrote.

The US government and a group of American victims and their families had appealed the lower court’s decision that struck down a provision of the law.

Among the plaintiffs are families who in 2015 won a $655 million judgment in a civil case alleging that the Palestinian entities were responsible for a series of terror shootings and bombings around Jerusalem from 2002 to 2004. They also include relatives of Ari Fuld, who was fatally stabbed by a Palestinian terrorist in 2018.

“The plaintiffs, US families who had loved ones maimed or murdered in PLO-sponsored terror attacks, have been waiting for justice for many years,” said Kent Yalowitz, a lawyer for the plaintiffs.

“I am very hopeful that the case will soon be resolved without subjecting these families to further protracted and unnecessary litigation,” Yalowitz added.

The ongoing fighting involving Israel and the Palestinians served as a backdrop to the case, with Fuld’s murderer released as part of a hostage-prisoner exchange earlier this year between Israel and the Gaza-ruling Hamas terror group.

US courts for years have grappled over whether they have jurisdiction in cases involving the Palestinian Authority and PLO for actions taken abroad.

Under the language at issue in the 2019 law, the PLO and Palestinian Authority automatically “consent” to jurisdiction if they conduct certain activities in the United States or make payments to people who attack Americans.

Roberts in Friday’s ruling wrote that Congress and the president enacted the jurisdictional law based on their “considered judgment to subject the PLO and PA (Palestinian Authority) to liability in US courts as part of a comprehensive legal response to ‘halt, deter and disrupt’ acts of international terrorism that threaten the life and limb of American citizens.”

New York-based US District Judge Jesse Furman ruled in 2022 that the law violated the due process rights of the PLO and Palestinian Authority. The New York-based 2nd US Circuit Court of Appeals upheld that ruling.

President Joe Biden’s administration initiated the government’s appeal, which subsequently was taken up by President Donald Trump’s administration. The Supreme Court heard arguments in the case on April 1.
