UNITED NATIONS (AP) — The family of independent U.N. investigator Francesca Albanese has sued the Trump administration over U.S. sanctions imposed on her last year for her criticism of Israel’s policies during the war with Hamas in Gaza, saying the penalties violate the First Amendment.

In a lawsuit filed Wednesday in the U.S. District Court in Washington, Albanese’s husband and minor child outlined the serious impact those sanctions have had on the family’s life and work, including the ability to access their home in the nation’s capital.

“Francesca’s expression of her views about the facts as she has found them in the Israeli-Palestinian conflict and about the work of the ICC is core First Amendment activity,” the lawsuit says, referring to the International Criminal Court. That tribunal has issued arrest warrants against Israeli officials, including Prime Minister Benjamin Netanyahu, over allegations of war crimes.

“At its heart, this case concerns whether Defendants can sanction a person — ruining their life and the lives of their loved ones, including their citizen daughter — because Defendants disagree with their recommendations or fear their persuasiveness,” according to the filing.

The White House did not immediately respond to requests for comment. A State Department spokesperson declined to comment on pending litigation

Albanese, the U.N. special rapporteur for the West Bank and Gaza, is a member of a group of experts chosen by the 47-member U.N. Human Rights Council in Geneva. She has been tasked with investigating human rights abuses in the Palestinian territories and has been vocal about what she has described as the “genocide” by Israel against Palestinians in Gaza.

Both Israel and the United States, which provides military support to its close ally, have strongly denied the genocide accusation. Washington had decried what it has called Albanese’s “campaign of political and economic warfare” against the U.S. and Israel before imposing sanctions on her in July after an unsuccessful American pressure campaign to force the international body to remove her from her post.

Shortly after being sanctioned, the Italian human rights lawyer told The Associated Press in an interview about the effect it would have on her, both personally and professionally.

“My daughter is American. I’ve been living in the U.S. and I have some assets there. So of course, it’s going to harm me,” Albanese said last summer. “What can I do? I did everything I did in good faith, and knowing that, my commitment to justice is more important than personal interests.”

But the sanctions have not dissuaded Albanese from her work or her viewpoints. She has continued to issue scathing reports about Israel’s activity, including one focused on what she said was the country’s “genocidal economy” in Palestinian territories.

Danny Danon, the Israeli ambassador to the United Nations, said last year after one of her reports that “she has taken the word ‘genocide,’ born from the ashes of the Holocaust, and turned it into a weapon — not to defend the victims of history, but to attack them.”

Israeli strikes have repeatedly disrupted the U.S.-brokered ceasefire deal from Oct. 10. There has been some progress, including the reopening of the Rafah crossing, but Israel and Hamas are divided over the timeline and scope of Israel’s withdrawal from Gaza and the disarmament of the militant group.

While special rapporteurs do not represent the U.N. and have no formal authority, their reports can step up pressure on countries, while their findings inform prosecutors at the ICC and other venues working on transnational justice cases.
