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

Review the primary official source.

In Immigrant Defenders Law Center v. Noem, the Ninth Circuit considered a district-court stay of the government’s 2025 reimplementation of the Migrant Protection Protocols, commonly called Remain in Mexico. The court concluded that the challenged implementation was reviewable final agency action and that the statutory injunction restriction did not bar the APA stay before it.

The case challenged implementation, not an abstract policy debate

The plaintiffs challenged the operational return of MPP and sought relief under the Administrative Procedure Act. The district court entered a stay under 5 U.S.C. section 705 while reviewing the merits.

The government appealed and argued that the immigration statute barred the relief and that there was no discrete final agency action.

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

The Ninth Circuit distinguished the form of relief and held that the district court’s APA stay was not barred by section 1252(f)(1) in the circumstances presented.

The ruling addressed threshold authority to preserve the status quo; it did not finally resolve every merits question concerning MPP.

The reimplementation was final agency action

The court found consummated agency decisionmaking because officials were directed to implement MPP across the southern border. Legal consequences flowed for the organization and the people it served.

A policy can be reviewable even when later implementation details remain. The inquiry focuses on whether the agency completed its decision and whether rights, obligations, or legal consequences followed.

The litigation remained ongoing

The panel affirmed the availability of the interim APA remedy and the final-agency-action finding. The underlying challenge continued in the district court.

Because immigration-policy litigation changes quickly, any use of this decision should verify later appellate orders, merits rulings, and current DHS practice.
