WASHINGTON—The Supreme Court dealt a setback to President Donald Trump’s immigration policy on Monday, declining to take up an administration appeal that sought a quick end to the Obama-era program protecting young, undocumented immigrants who came to the U.S. as children.
The high court’s action, which effectively requires Mr. Trump to finish litigating in the lower courts first, means that hundreds of thousands of program recipients may continue to renew their protections while legal challenges continue, a process that could take another year or longer.
The court’s action also relieves pressure on Congress, which has struggled to find a legislative replacement for the program begun by former President Barack Obama.
In September, Mr. Trump announced that the program, called Deferred Action for Childhood Arrivals, or DACA, would end on March 5. But two lower-court judges have issued injunctions blocking that plan for now and ordered administration officials to continue to process renewals, so Congress doesn’t face an imminent deadline.
The court’s action Monday was a rejection of an unusual request by the Justice Department, which had asked the justices to intervene now, even though appeals courts haven’t yet ruled on the cases.
The high court almost never grants such requests, but the department, citing time sensitivities, had argued the court should settle the issue without delay. That didn’t sway the justices, who turned down the request in a two-sentence order without recorded dissents.
