That middle of the night ruling was a strong signal that the majority of the court is fed up with being lied to. Except for Alito and Thomas of course. They understand that sometimes you have to lie to get things done, like stomping on the human and constitutional rights of those deemed undesirable.
Some nice Kafkaesque work going on: 'The government has no plans to remove anyone that’s filed a habeas petition.' The same government in the first place having asserted it can effectively prevent these 'detainees' from filing habeas petitions notwithstanding.

'Alito’s Emergency Deportation Dissent Misrepresents the Most Crucial Fact in the Case'
Late on Saturday night, Justice Samuel Alito released his dissent from the Supreme Court’s order—issued nearly 24 hours earlier—blocking the allegedly impending deportation of Venezuelan migrants under the Alien Enemies Act of 1798. It is highly unusual for the court to rush out an order before a dissenting justice has the chance to complete their opinion, reflecting the urgency of its intervention. That delay between the majority’s order and the publication of the dissent gave Alito plenty of time to raise persuasive objections to the court’s ruling. He failed on every level, misstating key points of law in a bid to bail out the president (which was joined only by Justice Clarence Thomas). Perhaps Alito’s most egregious misrepresentation, however, was not legal, but factual: The justice wrote that Trump administration lawyers “informed” a federal judge that “no” deportations “were planned to occur” on Friday or Saturday, so there was no need for emergency action. That is false. And what the Justice Department actually said in court reinforces the wisdom and necessity of the Supreme Court’s dramatic move.
Alito’s claim that there were no “planned” deportations originates from a hearing that U.S. District Judge James Boasberg held in Washington, D.C., on Friday evening. By that point, the American Civil Liberties Union had credible information from multiple sources that the government was loading Venezuelan migrants on buses heading to the Abilene, Texas, airport for rendition flights to El Salvador. These sources confirmed that federal officials had failed to provide these migrants with the due process rights recently afforded to them by the Supreme Court, including a meaningful opportunity to contest their removal. Instead, the government allegedly intended to deport them just 24 hours after coercing them into signing a “notice” in English that failed to inform them of their rights. Despite ample evidence of imminent, unlawful rendition flights, the conservative federal courts in Texas refused to act. The ACLU thus asked Boasberg for an emergency hearing on Friday night, and the judge summoned Justice Department attorney Drew Ensign to explain the administration’s plans.

Layered into this equivocation was an even deeper distortion. Ensign told Boasberg that “the government has no plans to remove anyone that’s filed a habeas petition”—that is, a challenge to their expulsion to El Salvador. But Ensign then admitted that the government is still preventing migrants from filing habeas petitions in the first place. The attorney insisted that despite the Supreme Court’s call for due process, federal officials did not have to inform migrants of their rights, or give them more than 24 hours’ notice before loading them on a flight to El Salvador. This threadbare process, Ensign told Boasberg, satisfied the government’s constitutional obligations. His assurance that “the government has no plans to remove anyone that’s filed a habeas petition” was therefore nearly meaningless given that the government claimed the authority to thwart those petitions from being filed in the first place.
In light of the full context and Ensign’s specific choice of words, Alito was simply wrong to claim that the Justice Department denied plans to fly out migrants on Friday or Saturday. Set aside the fact that DHS “reserve[d] the right to remove people” on Saturday. Set aside the bad-faith scheme hatched by administration officials to sabotage habeas petitions by denying migrants real due process. The truth is that Ensign himself refused to say with certainty that migrants were safe from imminent removal. And just last month, the government allegedly deprived him of real-time information about rendition flights—for the express purpose of hiding those flights from the court. Alito’s confidence that no migrants would be illegally renditioned was not just misplaced, but actively misleading.
