What is the test for a motion to stay a motion by the Department of Homeland Security to stay the motion?

deny the governments motions to stay and let these cases proceed in the ordinary course. See Nken v. Holder , 556 U.S. 418, 427, 43334, 129 S.Ct. 1749, 173 L.Ed.2d 550 (2009) (holding that a "stay is an intrusion into the ordinary processes of administration and judicial review, " and "[t]he party requesting a stay bears the burden of showing that the circumstances justify an exercise of [judicial] discretion" (citation omitted)).
