In a brief unsigned order issued shortly before 8 p.m. on Tuesday night, the court explained that the Biden administration was not likely to succeed – one of the criteria for obtaining this kind of request for emergency relief – in showing that its decision to end the policy was not “arbitrary and capricious” – that is, reasonable and reasonably explained. The order cited the court’s 2020 ruling in Department of Homeland Security v. Regents of the University of California, which rejected the Trump administration’s efforts to terminate the Deferred Action for Childhood Arrivals program, an Obama-era policy that protected people who were brought as children to the U.S. without authorization. In Regents, the court held that the Trump administration had not properly explained its decision to end DACA.
