The Trump administration faced an urgent legal challenge Sunday over reported plans to deport 11 Iranian nationals to Iran, a country under attack in a war launched by President Donald Trump and Israel.

The Iranian American Legal Defense Fund warned in court filings that carrying out the deportations Sunday without a judge’s approval would violate an existing federal court order. That order bars the administration from deporting Iranian nationals without sufficient notification to a federal judge in Washington, D.C.

According to the group, Immigration Customs and Enforcement planned to fly 10 men and one woman from Mesa, Arizona, to Islamabad, Pakistan, on Sunday. Iranian officials would then take them from Pakistan to Iran.

The group said the deportees could face persecution by Iranian officials after returning to the country. They could also confront dangers from potential U.S. airstrikes as the conflict continues.

“We have received credible information from multiple independent sources indicating that the U.S. government is proceeding with plans to deport Iranian nationals, including asylum seekers, to Iran, via Pakistan, despite a federal court order requiring five business days’ advance notice,” Yasmine Chubin, the group’s executive director, told MS NOW.

The administration had previously deported Iranians during the months before Trump and Israel launched the war against Iran. Lawyers and a relative of the detainees said some of the 11 people expected aboard Sunday’s planned flight had spent months in detention.

The Department of Homeland Security and the White House did not immediately respond to requests for comment. Meanwhile, Chubin described the reported operation as reckless and accused the government of appearing ready to disregard the court.

“Beyond the sheer recklessness of forcibly returning people to a country with which the United States is at war and against which it is actively conducting military strikes, the government appears poised to disregard a federal court order designed to ensure basic oversight and accountability,” Chubin said.

”These are human beings whose lives and safety are at stake. We have brought this urgent information to the court and expect the government to comply fully with its legal obligations.”

During an Oct. 15 court hearing, U.S. District Judge Ana Reyes compared deporting Iranians to their native country with sending people to Nazi Germany during World War II. ABC News reported her remarks last week, citing recently released court documents.

“We are talking about sending individuals in our care and custody to a country that we have bombed and we may continue bombing, and is a declared enemy of this country,” Reyes said. “It is like saying we have individuals in 1942 in this country that we are going to send back to Nazi Germany. That is the equivalent of what you are telling me.”

Reyes also threatened contempt proceedings against any government official who failed to follow her orders. “If anything happens that violates either of those two orders, I will hold every single person associated with violating it,” she said last month. “I will start contempt proceedings.”

It remained unclear what notice Reyes had received concerning the apparent deportation flight. Chubin said a party in the case filed a notice under seal on Nov. 3, meaning only that party and the judge could view its contents.

Chubin said the sealed filing could have come from the administration as notice of its deportation plans. Regardless, she maintained that a Sunday departure would violate Reyes’ order because the judge would not receive the required five business days of notice.

The dispute follows another court confrontation over administration deportation flights. Months after Trump returned to office, federal judge James Boasberg accused the administration of violating his order directing the Department of Homeland Security to halt government flights carrying deportees to El Salvador, including flights already over international air space.

Flight tracking records showed three U.S. government planes carrying 200 migrants continued toward El Salvador after Boasberg’s order, according to The New York Times. Boasberg launched a contempt investigation to determine which administration officials had defied him.

An appeals court is considering the Trump administration’s request to stop Boasberg’s inquiry. The administration argues that allowing the investigation to continue would infringe on presidential power.

In a separate case, federal judge Valerie Caproni in New York issued an order last Tuesday temporarily blocking the administration from deporting Afghan nationals to Afghanistan or Pakistan through Saturday, ABC News reported. Veterans groups warned that Afghans who helped the U.S. war effort could face Taliban retaliation.
