A split federal appeals court on Friday ruled that President Trump’s decision to rescind the Deferred Action for Childhood Arrivals (DACA) program was unlawful because “it was not adequately explained.”

The 4th Circuit Court of Appeals in Virginia found that the administration’s termination of the program was “arbitrary and capricious,” in line with a prior ruling from the 9th Circuit Court of Appeals.

The bulk of the ruling rests on how the administration laid out its decision to rescind the DACA program.
