SAN FRANCISCO (AP) — A federal appeals court on Friday blocked President Donald Trump’s plans to end protections for 600,000 people from Venezuela who have had permission to live and work in the United States, saying that plaintiffs are likely to win their claim that the Republican administration’s actions were unlawful.

A three-judge panel of the 9th U.S. Circuit Court of Appeals unanimously upheld a lower court ruling that maintained temporary protected status designations for Venezuelans while they challenge actions by Trump’s administration in court.

The 9th Circuit judges found that plaintiffs were likely to succeed on their claim that Homeland Security Secretary Kristi Noem had no authority to vacate or set aside a prior extension of temporary protected status because the governing statute written by Congress does not permit it.

Then-President Joe Biden’s Democratic administration had extended temporary protected status, commonly known as TPS, for people from Venezuela.

“In enacting the TPS statute, Congress designed a system of temporary status that was predictable, dependable, and insulated from electoral politics,” Judge Kim Wardlaw, who was nominated by President Bill Clinton, a Democrat, wrote for the panel. The other two judges on the panel were also nominated by Democratic presidents.

In an email, a spokesperson for the Department of Homeland Security blasted the decision as more obstruction from “unelected activist” judges.
