Staff Reports
Colorado Attorney General Phil Weiser this week sued the U.S. Department of Homeland Security and U.S. Immigration and Customs Enforcement to try to block renovation and operation of the proposed Hudson — also called the Big Horn — ICE detention center. The state is asking a federal judge for a preliminary injunction and wants the federal contract with private operator The GEO Group vacated until a full environmental review under the National Environmental Policy Act (NEPA) is completed.
The new lawsuit and what it asks the court to do
Colorado Attorney General Phil Weiser’s complaint names DHS, ICE, and The GEO Group and rests on one legal pivot: that federal officials skipped a NEPA environmental review before moving ahead with a multi‑year, roughly 1,200‑bed contract to reopen the shuttered Hudson Correctional Facility. The state asks the court to halt renovation, construction, and any operation of the Hudson/Big Horn site, to set aside the federal contract, and to order the agencies to do the NEPA analysis the state says was ignored.
Why this matters — beyond the press release
This isn’t just a fight over paperwork. State filings frame the alleged NEPA lapse as an excuse to raise real local concerns: strain on water and wastewater systems, traffic and emergency services, threats to wildlife and air quality, and infectious‑disease risks tied to large congregate facilities. Advocates in Colorado have already pursued zoning fights locally, and groups like GreenLatinos and the Colorado Immigrant Rights Coalition filed a parallel NEPA suit, so the state action joins a chorus of local resistance. But make no mistake: the federal contract at issue is large, expensive, and tied to national immigration enforcement priorities — that’s what makes the dispute a national story, not a town hall scrap.
Legal theater or legitimate review? — and the elephant of federal supremacy
Phil Weiser has made headline‑grabbing litigation a habit — this marks another in a long string of suits against the current federal administration, and he’s running for governor. Calling for NEPA review reads well to some voters, and it gives opponents of federal detention expansion a procedural hook. But the federal government and GEO Group will likely push back with familiar defenses: categorical exclusions, operational justifications, sovereign immunity, and the supremacy doctrine that already tripped up Colorado in earlier fights over state oversight of federal detention contracts. In short, the case will test whether NEPA can be used as a legal speed bump against federal immigration operations — or whether it’s being used, politically, to block what federal officials say they need to do.
Expect a fast and messy court fight. The state asked for a preliminary injunction, so the next steps are a government response, motions on jurisdiction and preemption, and possibly coordination with the private suits already in play. For conservatives who believe in enforcing the law and respecting federal prerogatives, this suit looks like a political detour that could tie up resources and slow efforts to manage migration flows. For opponents of the detention center, it’s a necessary legal check. Either way, the Hudson/Big Horn fight is now a testing ground for NEPA, federal contracting, and how much power a state AG can wield when he’s also on the campaign trail — and that’s worth watching as the litigation unfolds.
