On August 24, 2026, the U.S. Court of Appeals for the Ninth Circuit rescinded a preliminary injunction that limited U.S. Border Patrol stops and arrests in California’s Central Valley. The ruling removes significant legal constraints that had been in place since 2025, directly affecting immigration enforcement operations across agricultural and rural communities in the region.
What changed
In April 2025, U.S. District Judge Jennifer Thurston granted a preliminary injunction covering the Eastern District, which is California’s Central Valley. The order prevented Border Patrol from stopping people in violation of the Fourth Amendment or arresting them unless officers comply with federal law, and required that to carry out an arrest, officers must have reasonable suspicion of unlawful presence in the country.
The United Farm Workers of America had filed the underlying class action to challenge Border Patrol sweeps. The Ninth Circuit found that the federal district court failed to properly analyze whether plaintiffs had standing to seek forward-looking relief based on alleged harms in the past. The Ninth Circuit sent the lawsuit back to the district court to allow it to revisit its legal analysis after that court issued the preliminary injunction. In the meantime, Border Patrol agents are no longer bound by the district court’s restrictions.
Why it matters
For immigration practitioners and clients in California’s Central Valley, the lifting of the preliminary injunction represents an immediate change in enforcement dynamics. The appeals court panel lifted a preliminary injunction that had restricted Border Patrol immigration enforcement operations in California’s Central Valley after a lower court had imposed the limits following allegations that agents detained individuals without reasonable suspicion and conducted warrantless arrests.
This ruling does not dispose of the underlying case. The Ninth Circuit sent the lawsuit back to district court to allow it to revisit its legal analysis. However, practitioners advising clients in the region must now account for the absence of the earlier protective framework while appellate and district court litigation continues. The decision reflects the appellate court’s view of standing doctrine in prospective injunction cases and may affect other similar requests for forward-looking relief in other circuits.
Way forward
-
Reassess client detention risk: If you represent individuals in California’s Central Valley, particularly in agricultural or rural areas, review your client’s Fourth Amendment and constitutional protections in light of the lifted preliminary injunction. The district court’s earlier requirements that Border Patrol document reasonable suspicion and specific facts are no longer in force pending further litigation.
-
Monitor district court remand proceedings: The case returns to U.S. District Court for the Eastern District of California for reconsideration of standing. Follow the court docket for any new orders or preliminary injunction motions that might restore some or all of the earlier restrictions.
-
Document encounters: If your clients are subject to Border Patrol stops or detentions in the region, ensure detailed documentation of the facts, circumstances, and statements made by officers—such records may be critical if the case returns to the district court or if other litigation on similar claims proceeds.
-
Consult circuit precedent: The Ninth Circuit’s reasoning on standing for class-action prospective relief may affect other pending immigration-related injunction motions. Review whether your other cases involve similar standing questions.
