In Chafin v. Chafin, Justice Kagan cites the case of Nken v. Holder to discuss the tradition four factors considered in granting a stay.
Courts should apply the four traditional stay factors in considering whether to stay a return order: “‘(1) whether the stay applicant has made a strong showing that he is likely to succeed on the merits; (2) whether the applicant will be irreparably injured absent a stay; (3) whether issuance of the stay will substantially injure the other parties interested in the proceeding; and (4) where the public interest lies.’” Nken v. Holder, 556 U. S. 418, 434 (2009) (quoting Hilton v. Braunskill, 481 U. S. 770, 776 (1987)).
You may recall that in Nken, the Solicitor General supplied information to the Court about how ICE handles deportations, that turned out to be false. Following an order from Judge Rakoff, the DOJ confessed error.
My search shows that this is the first time SCOUTS has cited Nken since FCC v. AT&T in 2011.
