A federal judge has indicated she is leaning toward granting a preliminary injunction that would block a controversial plan to create an ICE facility in South County, after finding that plaintiffs demonstrated a “likelihood of success” in their argument that the project violates federal environmental law.
What changed
Judge Eumi Lee of the Northern District of California issued a tentative ruling on Friday in which she said that plaintiffs have demonstrated a “likelihood of success” in making their argument that the project violates federal environmental law. If granted, the preliminary injunction would prevent construction work from resuming at the 25-acre site until the resolution of a lawsuit brought by California Attorney General Rob Bonta and officials with Santa Clara County.
Lee will make a final ruling during a hearing scheduled for Sept. 8. (The hearing has now occurred as of today’s date.) The tentative ruling follows the federal government’s announcement on July 13, 2026, that it paused construction of a U.S. Immigration and Customs detention facility near Gilroy, in a deal with Santa Clara County and the State of California.
Why it matters
The tentative ruling signals judicial skepticism of the ICE facility project on multiple grounds. The state and county lawsuit alleges the facility would violate federal environmental laws because the government failed to produce an environmental assessment or impact statement before entering the lease and starting construction, and claims the project would run afoul of federal immigration law because it is planned for land zoned exclusively for agricultural use, near habitat for several endangered and threatened species.
For immigration practitioners, this ruling is significant because it demonstrates how federal courts may scrutinize agency detention capacity expansion efforts when environmental and administrative law defenses are available. A final preliminary injunction would halt active construction and likely extend the administrative litigation timeline substantially. The judge’s preliminary findings on likelihood of success on environmental law claims may also affect how courts review similar ICE construction or detention projects nationally.
Way forward
- If you represent detained immigrants in the Northern District of California: Monitor the Sept. 8 hearing outcome. A final injunction blocking the facility would reduce ICE’s detention bed capacity in the region, potentially affecting bond/release decisions and case processing.
- If you practice immigration enforcement or compliance law: Review the final ruling when issued. It may provide persuasive authority on the scope of NEPA compliance required for federal immigration detention infrastructure.
- If you work on environmental or administrative law affecting immigration: Track appellate developments. The Trump administration may appeal, and the 9th Circuit’s treatment of environmental law constraints on federal agency action could shift enforcement capacity nationwide.
- For local/state advocacy practitioners: The ruling affirms that state and county governments can mount credible legal challenges to federal immigration projects on environmental and land-use grounds.
