The order, issued by Judge Michael W. Fitzgerald on April 15, 2026, enjoins respondents from re-detaining the petitioner unless they comply with the process required under 8 C.F.R. §§ 241.4(l)(1) and 241.13(i).
The litigation involves Castillo as the petitioner and the Facility Administrator of Desert View Annex, Kristi Noem as Secretary of the U.S. Department of Homeland Security, Todd Lyons as Acting Director of U.S. Immigration and Customs Enforcement, and Pamela Bondi as U.S. Attorney General.
The court’s ruling follows an initial temporary restraining order granted on March 23, 2026, which Castillo obtained through an ex parte application.
Following the temporary order, the court issued an Order to Show Cause asking the government to explain why the temporary restriction should not be converted into a preliminary injunction.
On April 15, the court reviewed the government’s response to that order and determined that good cause existed to grant the preliminary injunction under Federal Rule of Civil Procedure 65.
The injunction specifically targets the conditions under which Castillo can be held in custody, tying the legality of his detention to adherence to the cited Code of Federal Regulations sections.
