Immigrant Defenders: Reimplementing Remain in Mexico Was Reviewable Final Agency Action

Review the primary July 18, 2025 Ninth Circuit interim order.

The Ninth Circuit allowed an immediate appeal of a district court’s pause on the 2025 reimplementation of Remain in Mexico, rejected the government’s principal threshold objections and found the challenger's statutory APA case likely to succeed. Yet the court also narrowed the pause: Only Immigrant Defenders Law Center’s current and future clients were protected during the appeal. The distinction between reviewability, probable illegality and the proper scope of interim relief explains that result. Immigrant Defenders Law Center v. Noem, No. 25-2581 (9th Cir. July 18, 2025), order, pages 8–9, 19–20, 38–40.

The case challenged implementation, not an abstract policy debate

The Migrant Protection Protocols (MPP), commonly called Remain in Mexico, used section 1225(b)(2)(C)’s authority to return certain people arriving by land to a contiguous country while removal proceedings continued. The majority accepted that the Executive possessed that discretionary authority; the dispute concerned the way the 2019 policy was being restarted in 2025. ImmDef argued that its implementation obstructed statutory asylum and counsel rights. Order, pages 7–12, 31–35.

Two different stays were involved. The district court used Administrative Procedure Act section 705 to postpone the reimplementation pending review. The government then asked the court of appeals to stay that judicial order pending appeal. ImmDef separately moved to dismiss the appeal because the district court’s order was not a final judgment. Confusing those requests can reverse the apparent meaning of the result: Granting part of the government’s stay request reduced, rather than expanded, the protection supplied by the district court. Order, pages 8–9, 12–20.

The panel applied Carson’s three requirements for immediately appealing a nonfinal order with injunctive effects. The district court’s section 705 pause operated much like a preliminary injunction after adversarial briefing and a hearing. Although the government’s concrete harm evidence was scant, the majority found a sufficient risk to immigration implementation and foreign-affairs negotiations, and concluded that a later final judgment could not restore the lost opportunity to exercise that authority during the litigation. It therefore denied the motion to dismiss the appeal. Order, pages 13–19.

Section 1252(f)(1) did not bar the section 705 stay

The government challenged ImmDef’s standing as well as the remedy. The majority found injury to an existing legal-services operation, not merely disagreement with a policy. The record described cross-border travel, confidential meeting space, international communications and staffing required to continue representing the same constituency. Reuse of the 2019 guidance supported an imminent recurrence of those obstacles. That concrete interference with core representation work distinguished the claim from spending money merely to research or advocate against government action. Order, pages 22–26.

Section 1252(f)(1) restricted lower-court injunctions restraining the operation of specified immigration provisions. The government argued that the section 705 pause had the same practical effect and was therefore barred. The majority instead focused on the kind of remedy: An injunction directs a party’s conduct, while a stay temporarily suspends the source of authority being reviewed. Relying on that distinction, the provision’s injunctive-relief language and the presumption favoring agency review, it held that the statute did not bar this section 705 stay. Order, pages 26–29.

That did not conflict with treating the order as sufficiently injunction-like for an immediate appeal. The appealability inquiry examined practical effects under Carson; the section 1252(f)(1) inquiry examined the legal operation and statutory category of the remedy. The panel answered those different questions separately. Our Nken analysis explains the underlying stay-versus-injunction distinction in an individual removal case. Order, pages 15–16, 26–29.

The reimplementation was final agency action

Under Bennett v. Spear, an action must complete the agency’s decisionmaking rather than remain tentative, and determine rights or obligations or produce legal consequences. The majority applied both parts. The January 20, 2025 executive order announced reimplementation using the original policy documents; DHS announced an immediate restart the following day. Staff were bound to implement the decision, and its consequences for ImmDef and the people it served were actual or immediately threatened. Order, pages 29–30.

The earlier termination litigation did not make the restart legally invisible. The majority explained that a Texas court’s section 705 stay had postponed, not vacated, the prior administration’s termination action. The 2025 restart was a deliberate reversal of the previous final administrative decision, with renewed legal and practical effects. That was enough for reviewability even though implementation depended on further operational steps. Finality did not itself establish illegality; it identified an agency action the court could review. Order, pages 29–30.

Our Biden v. Texas analysis concerns the earlier termination decision and the discretionary return statute. This order addressed a later restart, different claims and emergency relief. Preserve the actual dated agency documents and the earlier orders rather than treating every dispute about MPP as the same decision.

Why interim protection was limited to ImmDef’s clients

The majority found a strong likelihood that the restart violated the APA by disregarding asylum seekers’ statutory ability to apply with counsel. It connected the INA’s return authority to its other provisions protecting counsel of choice at no expense to the government. The claimed problem was not simply that seeking protection from Mexico was inconvenient: The record described a severely limited prehearing consultation window, inadequate privacy and obstacles to maintaining representation. The majority also considered DHS’s own earlier account of access and hearing-notice problems. Order, pages 31–35.

For the stay factors, the majority recognized some government irreparable harm but characterized its evidence as weak at that stage. It weighed that against concrete harm to ImmDef’s representation work, staff safety, finances and existing programs. Nevertheless, it tailored the district court’s broad pause to protect the plaintiff before it. The government itself proposed a client-only limit as sufficient to give ImmDef complete relief. Order, pages 35–39.

The resulting command was specific: No current or future ImmDef clients were to be enrolled in MPP during the pendency of that appeal. The panel granted the government’s stay motion in part and directed expedited merits briefing. It did not finally affirm the district court’s nationwide order. The majority used the complete-relief principle as equitable guidance while expressly recognizing that Trump v. CASA had not decided the APA question. Order, pages 38–40.

Limits and practical implications

Judge R. Nelson dissented while agreeing that appellate jurisdiction existed. The standing disagreement concerned how to apply Havens Realty after FDA v. Alliance for Hippocratic Medicine, not merely whether the organization opposed MPP. The majority treated cross-border representation as continuation of an established service impaired by the policy. Nelson viewed the new initiatives as activities voluntarily created in response to MPP, not interference with preexisting core operations. He argued that circuit decisions allowing standing through frustration of mission and diverted resources were incompatible with the Supreme Court’s intervening decision. Order, pages 22–26, 42 n.1, 48–61.

Nelson also objected to what he described as dueling stays: The Texas order prevented termination, while this district court’s order blocked reimplementation. The majority’s finality analysis had drawn a different distinction, explaining that the Texas stay suspended rather than vacated the termination decision and that the 2025 restart was a new reviewable action. Keeping those positions separate explains the disagreement without purporting to determine how later orders changed the program. Order, pages 29–30, 41, 45.

On the merits, Nelson read the INA’s return authority and counsel provisions differently and would have granted the government a full stay. He expressly took no position at that stage on section 1252(f)(1) or final agency action. Those are separate-opinion positions, not additional majority holdings. Order, pages 48 n.4, 61–74.

The majority’s probable-success reasoning rested on statutory APA claims; it did not decide the plaintiffs’ First Amendment theory. For practical use, separate four records: The agency decision and its consequences, the organization’s concrete service injury, the client relationship relevant to the remedy, and the operative court orders. They support different questions—reviewability, standing, scope of protection and what may happen next.

This analysis explains the July 18, 2025 interim order. It does not establish present MPP operations or that the client-based protection remains in force today. Before relying on it for an individual matter, check later appellate and district-court orders and current DHS action. A person’s similar circumstances alone did not establish inclusion in the client-limited relief described here.
