WASHINGTON — A divided Supreme Court on Monday allowed the Trump administration to restart swift removals of migrants to countries other than their homelands, lifting for now a court order requiring they get a chance to challenge the deportations.

The high court majority did not detail its reasoning in the brief order. Justice Sonia Sotomayor, joined by the other two liberal justices, issued a scathing dissent.

Department of Homeland Security spokeswoman Tricia McLaughlin suggested third-country deportations could restart soon. “Fire up the deportation planes,” she said in a statement, calling the decision “a victory for the safety and security of the American people.”

But a judge said one deportation flight originally bound for South Sudan wouldn’t be completing the trip right away.

The immigrants on board the May flight were from countries including Myanmar, Vietnam and Cuba. They had been convicted of serious crimes in the U.S., and immigration officials said they were unable to return them quickly to their home countries.

They face possible “imprisonment, torture and even death,” if sent to South Sudan, said their attorney Trina Realmuto, executive director of the National Immigration Litigation Alliance.

U.S. District Judge Brian E. Murphy in Boston said a previous order allowing them to bring up those concerns in court remains in force. The immigrants have been diverted to a naval base in Djibouti.

The case comes amid a sweeping immigration crackdown by Republican President Donald Trump’s administration, which has pledged to deport millions of people who are living in the United States illegally.

“The Constitution and Congress have vested authority in the President to enforce immigration laws and remove dangerous aliens from the homeland,” White House spokeswoman Abigail Jackson said. The Supreme Court’s action “reaffirms the President’s authority to remove criminal illegal aliens from our country and Make America Safe Again.”

Sotomayor wrote that the court’s action exposes “thousands to the risk of torture or death” and gives the Trump administration a win despite earlier violating the lower court’s order.

“The government has made clear in word and deed that it feels itself unconstrained by law, free to deport anyone anywhere without notice or an opportunity to be heard,” she wrote in the dissent, joined by Justices Elena Kagan and Ketanji Brown Jackson.

South Sudan, the world’s newest and one of its poorest countries, has endured repeated waves of violence since gaining independence from Sudan in 2011, and escalating political tensions in the African nation have threatened to devolve into another civil war.

The Justice Department said in court documents that the government is weighing the order to decide its next steps.

The Supreme Court action halts Murphy’s April order giving immigrants a chance to argue deportation to a third country would put them in danger — even if they have otherwise exhausted their legal appeals.
