Chief Justice John Roberts, writing the majority opinion in the June 2020 Supreme Court ruling on the Deferred Action for Childhood Arrivals program, did not rule on the constitutionality of the policy. Rather, the ruling focused on whether the Trump Administration had complied with the procedural requirement to “provide a reasoned explanation” for rescinding DACA. Justice Roberts stated that the court's decision did not decide “whether DACA or its rescission are sound policies.”
When Attorney General Jeff Sessions announced in 2017 that DACA would be rescinded, provoking the lawsuit that led to this decision, he called it an unconstitutional exercise of authority by the Obama Administration.
