Justice Samuel Alito dissented in the Supreme Court’s decision Saturday to block the Trump administration from deporting a group of migrants.

In his five-page dissent released Saturday shortly before midnight, Alito, joined by Justice Clarence Thomas, wrote that in his view, the court’s decision to intervene overnight was not “necessary or appropriate.”

The court’s unsigned, one-paragraph order came after a fast-moving legal battle late Friday. The American Civil Liberties Union had rushed to several lower courts, then to the Supreme Court, claiming that the Trump administration was planning to deport more Venezuelan migrants, presumably to El Salvador, with little to no due process.

“In sum, literally in the middle of the night, the court issued unprecedented and legally questionable relief,” Alito wrote in his dissent, “without giving the lower courts a chance to rule, without hearing from the opposing party, within eight hours of receiving the application, with dubious factual support for its order, and without providing any explanation for its order.”
