The application is also treated as a petition for a writ of certiorari, and the petition is granted (case No. 26-426). The parties are directed to brief and argue the following questions: (1) Whether the district court had jurisdiction over Respondents’ claims. (2) Whether the district court had authority to enter classwide declaratory relief and APA vacatur under 8 U. S. C. §1252(f)(1). (3) Whether the Government’s Guidance on third-country removals is unlawful under 8 U. S. C. §1231(b), the Due Process Clause, or FARRA/CAT and its implementing regulations. (4) Such other questions that the Government determines are appropriate for the proper disposition of the case. The Clerk is directed to establish a briefing schedule that will allow the case to be argued in the December 2026 argument session. The stay shall terminate upon the sending down of the judgment of this Court. Justice Sotomayor, Justice Kagan, and Justice Jackson would deny the application for stay.
