A federal appeals court rejected the Trump administration’s request to revoke the temporary legal status of nearly a million migrants living in the country.

In an order Monday, the 1st U.S. Circuit Court of Appeals declined to put a hold on a judge’s order that stopped the Department of Homeland Security (DHS) from terminating parole protections for people who entered the country through the CBP One app.

DHS’s move would have revoked legal status for nearly a million people who came to the U.S. under the Biden administration. Of the roughly 985,000 migrants who used the app, many were often permitted to seek asylum and given a temporary work authorization. 

The three-judge panel in Boston, comprised of appointees of Democratic presidents, said DHS Secretary Kristi Noem has not made a “strong showing” that the termination of the parole for the migrants is “likely to be sustained on appeal.” 

Noem has not shown the “balance of harms and the public interest weigh so heavily in her favor to warrant a stay of the district court order pending the outcome of this appeal in the absence of a strong showing that the Secretary will prevail,” the panel wrote. 

District Judge Indira Talwani halted DHS’s action on April 25, which she said revoked protections without the necessary case-by-case review process. 

The Hill has reached out to DHS for comment, but a spokesperson told Reuters that the administration is “committed to restoring the rule of law to our immigration system.” 

“No lawsuit, not this one or any other, is going to stop us from doing that,” spokesperson Tricia McLaughlin said. 

The administration had begun sending email notices to impacted migrants telling them to self-deport through the new version of the app, now called CBP Home. 

Migrant rights advocates filed a lawsuit challenging DHS’s order. Karen Tumlin, a lawyer for immigrant rights group Justice Action Center that pursued the case, celebrated the appeal’s court decision. She called DHS’s action “reckless and illegal,” Reuters reported. 

The administration may now take the case to the Supreme Court to intervene.
