The outcome seems certain to elevate the issue in Trump’s campaign, given the anti-immigrant rhetoric of his first presidential run in 2016 and immigration restrictions his administration has imposed since then.
The justices rejected administration arguments that the 8-year-old Deferred Action for Childhood Arrivals Program is illegal and that courts have no role to play in reviewing the decision to end DACA.
Chief Justice John Roberts wrote for the court that the administration did not pursue the end of the program properly.
Justice Clarence Thomas, in a dissent joined by Justices Samuel Alito and Neil Gorsuch, wrote that DACA was illegal from the moment it was created under the Obama administration in 2012.
Justice Brett Kavanaugh wrote in a separate dissent that he was satisfied that the administration acted appropriately in trying to end the program.
