The migrants were the subject of a lawsuit that halted their deportation to South Sudan and diverted them to a U.S. military base in Djibouti.

A federal judge in Boston rejected a final plea Friday from the immigrants’ lawyers, saying the Supreme Court authorized the transfers.

While the Supreme Court issued rulings demanding the Trump administration respect immigrants’ right to due process and undo Abrego Garcia’s unlawful deportation to El Salvador, the court’s conservative supermajority recently greenlit the president’s efforts to send immigrants to third countries, or countries that are not their own.
