A Trump-appointed federal judge temporarily blocked key provisions of a Colorado law that singled out the GEO Group's Aurora ICE Processing Center for special oversight, ruling the state likely violated the Constitution by targeting a federal contractor.
Chief U.S. District Judge Daniel Domenico issued a preliminary injunction Thursday halting the most aggressive provisions of Colorado House Bill 26-1276, a state law that imposed unannounced inspections on the Aurora facility at least once every three months, forced GEO Group to pay for those inspections, and authorized civil penalties of up to $50,000 for each refusal to let inspectors in. Fox News Digital reported the ruling relied on the Constitution's supremacy clause, the principle that federal law and federal operations override conflicting state regulation.
Democratic Governor Jared Polis signed the bill into law on June 4. By the time the ink dried on the injunction, Domenico had laid out a straightforward constitutional problem: the Aurora ICE Processing Center was the only facility in Colorado subject to the law's additional regulations as of May. The bill applied to no one else.
The judge's order did not hold back about what the state had done. Domenico wrote that GEO Group "is singled out for a special bill that applies to no other facility." He rejected Colorado's argument that the law merely brought GEO into compliance with regulations already imposed on other detention centers.
"And though Colorado argues that the law only brings GEO into compliance with existing state regulations applied to other detention facilities, that law singles out this one category of facility for a separately defined set of restrictions and rulemaking."
The distinction matters. Colorado tried to frame HB 26-1276 as routine public-safety regulation. Domenico found the opposite. The requirement for a set number of unannounced visits, he noted, "does not appear elsewhere." And the state itself acknowledged that the penalty scheme, those $50,000-per-refusal fines, was not imposed on other facilities.
Domenico cited Supreme Court precedent holding that federal government activities must generally remain free from state regulation. Those protections, he wrote, extend to private contractors carrying out federal operations. GEO Group operates the Aurora facility under a federal contract with U.S. Immigration and Customs Enforcement. Colorado passed a law that burdened that specific contractor and no one else.
The judge put it bluntly:
"That other facilities might have some similar regulatory burdens does not change the fact that none of them are required to comply with HB 1276. As GEO notes, the extent of the additional burden is irrelevant for purposes of this test."
And that, Domenico concluded, "is sufficient to establish that HB 1276 discriminates against GEO based on its status as a federal contractor."
The ruling fits a broader pattern of federal courts stepping in when state or federal authorities overreach. In a separate case this year, a federal judge blocked the FBI headquarters relocation to the Reagan Building, ordering a return to the original Greenbelt plan after finding procedural violations.
Domenico's injunction was targeted, not total. He blocked the unannounced inspection mandate and its associated penalty provisions, the teeth of the law. But he left other sections untouched, including requirements for reporting, staffing levels, onsite medical and mental health professionals, and rules governing the housing of minors.
Why? Colorado told the court those provisions were not currently being enforced and would require future rulemaking before they took effect. So the judge saw no immediate harm to block.
The bill's full scope was broad. HB 26-1276 would have required potential annual reports covering people with chronic health conditions and disabilities, dietary restrictions, access to attorneys, and access to spaces for worship. It also addressed staffing ratios and the housing of children held at the facility.
None of those provisions are dead. They remain on the books. If Colorado moves to enforce them, GEO could challenge them separately, but for now, the fight centered on the inspections and the fines.
Courts have increasingly become the arena where immigration enforcement battles play out. In Arizona, a federal judge rejected a tribal bid to block border wall construction, citing a 1907 Roosevelt-era proclamation, another case where the supremacy of federal authority over state and local objections proved decisive.
Democratic Attorney General Phil Weiser tried to frame the injunction as a minor setback. In a statement Thursday, he characterized the ruling as limited in scope:
"Today's ruling granted the GEO Group a narrow, temporary injunction against one provision of a new 2026 law, not the broad relief it sought, and leaves Colorado's existing public health and safety authority intact."
Weiser then shifted to a different front. He referenced a separate lawsuit Colorado filed the day before the ruling, seeking to force GEO to cooperate with a state investigation into tuberculosis at the Aurora facility. Colorado health officials confirmed an active tuberculosis case at the detention center on June 22, just eighteen days after Polis signed the oversight bill into law.
Weiser framed the tuberculosis suit as an exercise of existing state authority, distinct from HB 26-1276:
"Separately, our lawsuit filed yesterday seeks to enforce that existing authority and require GEO to cooperate with the state's investigation into tuberculosis at the Aurora facility, and we will continue using every available tool to protect the health and safety of Coloradans."
The timing raises questions. Colorado signed a sweeping oversight law targeting one facility, then filed a separate lawsuit against the same facility the day before a federal judge ruled on the first challenge. Whether the tuberculosis suit represents a genuine public-health concern or a backup strategy to maintain pressure on GEO after the injunction, the state is clearly not backing down.
State officials clashing with federal immigration enforcement is nothing new. In New Jersey, Governor Sherrill claimed ICE blocked her from accessing a federal detention facility, drawing accusations that she was playing politics rather than pursuing genuine oversight.
Domenico set the preliminary injunction to expire on October 15, the same date GEO Group's existing federal contract to operate the Aurora site runs out. That deadline creates a natural endpoint. If GEO's contract is renewed, the constitutional questions will persist. If it is not, the law's target disappears.
Fox News Digital reached out to both GEO Group and Governor Polis's office for comment. Neither response was reported.
The case underscores a recurring tension in immigration policy. Blue-state legislatures pass laws designed to obstruct or regulate federal immigration operations. Federal courts then evaluate whether those laws cross constitutional lines. In this instance, Colorado did not write a general regulation that happened to apply to an ICE facility. It wrote a law that applied to one facility, operated by one company, under one federal contract, and imposed penalties found nowhere else in state law.
Judicial intervention in politically charged policy disputes has become routine across multiple domains. A federal judge recently struck down gun registration rules in fifteen states after Congress zeroed out the NFA tax, demonstrating how courts continue to serve as the final check when legislative action collides with constitutional limits.
Domenico's ruling did not resolve the larger fight over the Aurora facility. It blocked the most coercive provisions of a law that targeted a single federal contractor, and it did so on grounds as old as the Constitution itself: states cannot single out federal operations for special burdens. Colorado can argue the law was about public safety. The judge looked at who the law applied to and found the answer telling.
When a state writes a law that fits only one company, at one address, doing one job for the federal government, and then attaches $50,000 fines to it, the supremacy clause exists for exactly that reason.
