The Supreme Court on Thursday rejected the Trump administration’s attempt to dismantle the Deferred Action for Childhood Arrivals (DACA) program, which protects undocumented immigrants brought to the country as children. The decision is a reprieve for nearly 650,000 recipients known as “dreamers.”

The 5 to 4 decision was written by Chief Justice John G. Roberts Jr. and joined by Justices Ginsburg, Kagan, Breyer and Sotomayor.

The Trump administration had tried for more than two years to end DACA, announced by President Barack Obama in 2012 to protect qualified young immigrants who had been brought illegally to the country from deportation.

Agreeing with the lower courts, Roberts said the Trump administration did not follow the Administrative Procedures Act and did not properly weigh how ending DACA would affect those who had come to rely on its protections against deportation, and the ability to work legally in the U.S.
