No. 25-3050 MARGARITO CASTAÑON-NAVA, et al., Plaintiffs-Appellees, v.

U.S. DEPARTMENT OF HOMELAND SECURITY, et al., Defendants-Appellants.

Appeal from the United States District Court for the Northern District of Illinois, Eastern Division. No. 1:18-cv-3757 — Jeffrey I. Cummings, Judge.

ARGUED DECEMBER 2, 2025 — DECIDED DECEMBER 11, 2025

Before KIRSCH, LEE, and PRYOR, Circuit Judges. LEE, Circuit Judge. In 2022, the Department of Homeland Security and the U.S. Immigration and Customs Enforcement (“Defendants”) entered into a Consent Decree with Plaintiffs negotiated over the course of two different administrations. In this lawsuit, Plaintiffs’ principal claim was that Defendants ’ practice of warrantlessly arresting individuals—absent probable cause that the subjects were likely to escape before warrants could be obtained—violated 8 U.S.C. § 1357(a)(2), 2 No. 25-3050

which governs immigration arrests effectuated without a warrant. And so, in the Consent Decree, Defendants agreed to issue a “Broadcast Statement of Policy” affirming “the underlying laws and policies applicable to all arrests effected under 8 U.S.C. § 1357(a)(2),” provide relevant training, and document compliance. Dkt. 155-1 at 5, 6, 17. 1 In exchange, Defendants obtained a dismissal with prejudice and release of all related claims, “avoid[ing] the substantial expense, inconvenience, and distraction of further protracted litigation … and finally put[ting] to rest and terminat [ing]” the action. Id. at 2. Defendants do not challenge the validity of the original Consent Decree or the authority of the district court to enter it.

Instead, Defendants seek a stay pending appeal of two recent district court orders issued on October 7 and November 13, 2025. First, they challenge the district court’s October 7 order extending the term of the Consent Decree by 118 days after finding that Defendants had failed to substantially comply with the Consent Decree. Second, Defendants seek to stay the district court’s November 13 order requiring the release of 13 individuals, whom both parties agree were arrested in violation of § 1357(a)(2), as well as approximately 442 individuals who (in the district court’s words) “it stands to reason” were “potentially” arrested in violation of § 1357(a)(2).

For the reasons explained below, Defendants’ request for a stay pending appeal of these rulings is granted in part and denied in part. The request for a stay of the October 7

No. 25-3050 3

extension order is denied. The request for a stay of the November 13 order is granted under the terms described below.

I

A. The Consent Decree In 2018, Plaintiffs filed this class action against the Department of Homeland Security (“DHS”), Immigration and Customs Enforcement (“ICE”), and various federal officials, alleging that they were arresting noncitizens without a warrant in violation of 8 U.S.C. § 1357(a)(2). This provision provides, in relevant part:

Any officer or employee of the Service authorized under regulations prescribed by the Attorney General shall have power without warrant … to arrest any alien in the United States, if he has reason to believe that the alien so arrested is in the United States in violation of [any law or regulation made in pursuance of law regulating the admission, exclusion, expulsion, or removal of aliens] and is likely to escape before a warrant can be obtained for his arrest …. After several years of discovery and motion practice, the parties negotiated a settlement and signed the Consent Decree on November 29, 2021. On February 8, 2022, the district court granted final approval of the agreement, entered the Consent Decree, and certified the following class pursuant to Federal Rule of Civil Procedure 23(e): “All current and future persons arrested without a warrant for a civil violation of U.S. immigration laws within the area of responsibility of the ICE Chicago Field Office.” Dkt. 158 at 4.

As part of the Consent Decree, Defendants agreed to issue a “Broadcast Statement of Policy” to all ICE officers affirming 4 No. 25-3050

ICE’s obligations under § 1357(a)(2). Dkt. 155-1 at 6–7, 17–19. Defendants additionally agreed to adopt or amend current training materials to ensure compliance with § 1357(a)(2) and maintain records documenting warrantless arrests. Id. at 7–8.

The Consent Decree also laid out how the parties would address any future claims that Defendants had violated the terms of the Consent Decree. For example, in those instances where Plaintiffs believe that Defendants have arrested and detained an individual in violation of the agreement, they can raise the issue with Defendants and file a motion to enforce if the parties are unable to agree upon a resolution. Id. at 10–11. Furthermore, if Plaintiffs come to believe that Defendants have repeatedly and materially violated the Consent Decree, they can file a motion, after conferring with Defendants, and seek appropriate equitable relief from the court. Id. at 11. 2 Under its terms, the Consent Decree was scheduled to expire on May 12, 2025, three years after its effective date. However , the parties agreed that it would only terminate on that date “absent a pending motion to enforce its terms.” Id. at 5.

2 Release as a remedy for class members comports with the remedy provided when someone is arrested in violation of federal law. See Arias v. Rogers, 676 F.2d 1139, 1142 (7th Cir. 1982) (“If the petitioners had been arrested illegally by [immigration] officers and carted off to jail and the [agency] had made no move to begin deportation proceedings, the petitioners would have been entitled to obtain their freedom through a habeas corpus proceeding because their detention would have violated the Fourth Amendment, which forbids ‘unreasonable ... seizures,’ including arrests, of persons whether or not they are citizens; and the immigration laws, specifically 8 U.S.C. § 1357(a)(2).”).

No. 25-3050 5

B. The October 7 Order On March 13, 2025, a few months before the scheduled termination date, Plaintiffs filed a motion to enforce, asserting that ICE had arrested 26 individuals in violation of § 1357(a)(2) and the Consent Decree. Dkt. 164.

On April 14, 2025, Plaintiffs also filed a motion to modify the final approval order enforcing the terms of the Consent Decree under Federal Rule of Civil Procedure 60(b)(5). Dkt. 177. In it, Plaintiffs requested that the court extend the Consent Decree by an additional three years in light of, in their view, Defendants’ repeated material noncompliance. In response , Defendants argued that they had not violated the Consent Decree and that Plaintiffs had not satisfied Rule 60(b)(5)’s requirements to seek a modification of the Consent Decree. Dkt. 184.

While both motions were pending, a senior DHS official sent an email on June 11, 2025, unilaterally declaring that ICE’s obligations under the Consent Decree were terminated:

Despite a pending motion to enforce the settlement agreement and motion to extend the settlement agreement , it remains terminated. Accordingly, I hereby rescind the May 27, 2022, Castañon-Nava Settlement Obligation statement of policy.

Dkt. 193 at 1.

On October 7, 2025, the district court granted the enforcement motion in part, finding that 22 of the 26 individuals identified in the enforcement motion were arrested in violation of the Consent Decree. Noting that the 22 individuals had already been released, the only relief that remained were fees 6 No. 25-3050

and compliance certificates. Defendants do not challenge that ruling here.

In the same order, the district court also granted Plaintiffs’
