A federal appeals court ruled Tuesday that Florida's immigration detention facility in the Everglades, dubbed "Alligator Alcatraz" by its critics, can remain open, delivering a clear win for the state and for the Trump administration's push to expand detention capacity. The 11th U.S. Circuit Court of Appeals, in a 2-1 decision, upheld its earlier move to block a lower-court order that would have forced the facility to wind down operations over alleged violations of federal environmental law.
The ruling turned on a straightforward question: who controls the facility? The majority said Florida does, and that means the National Environmental Policy Act, which requires federal agencies to assess environmental impacts before major actions, does not apply.
Environmental groups had argued that because the detention center houses illegal immigrants on behalf of the federal government, it should be treated as a federal project subject to NEPA review. The appeals court disagreed. And the decision lands at a moment when lower-court judges across the country have repeatedly tried to slow or stop Trump-era immigration enforcement, only to see appellate courts push back.
Gov. Ron DeSantis' administration built the detention center last year at the Dade-Collier Training and Transition Airport site, an area surrounded by protected wetlands within the Everglades ecosystem. The facility was constructed, as Fox News reported, to support President Donald Trump's immigration agenda. Florida officials also built a second immigration detention center in northern Florida.
The center's capacity is expected to reach up to 5,000 detainees, Just The News reported, and it was created under an emergency order by DeSantis.
Two environmental groups, Friends of the Everglades and the Center for Biological Diversity, sued, arguing the project should have undergone a federal environmental impact review. U.S. District Judge Kathleen Williams agreed and issued a preliminary injunction last year ordering a gradual winding down of operations.
That order went further than just halting new arrivals. As the New York Post reported, Williams' August 21 preliminary injunction would have required utilities and infrastructure at the facility to be removed within 60 days, effectively dismantling it. Judge Barbara Lagoa, writing for the earlier appellate stay, said it was "entirely unclear" how the district court concluded it could order "the proactive dismantling of the Facility by way of a mandatory preliminary injunction."
The appeals court paused Williams' order just days after it was handed down in August, pending a hearing held earlier this month. Tuesday's ruling made that stay permanent by upholding the appellate court's earlier decision on the merits.
The majority's logic was direct. Judge William Pryor, as the Washington Times reported, wrote that because Florida "retain[ed its] state law authority to make the decisions concerning the project," the facility was not under federal control and its construction did not trigger NEPA.
The court noted that Florida had received no federal reimbursement at the time Judge Williams issued her preliminary injunction. Williams had found that a federal reimbursement plan had effectively already been made, but the appeals court saw it differently. The majority wrote plainly:
"Florida, not federal, officials constructed the facility. They control the land and 'entirely' built the facility at state expense."
That distinction matters. NEPA applies to federal actions. If a state builds a facility on state land with state money, the fact that it serves a federal purpose, detaining illegal immigrants, does not automatically convert it into a federal project requiring an environmental impact statement. That was the core of the majority's holding.
This ruling fits a broader pattern of appellate courts siding with Florida on immigration enforcement, even when lower-court judges have tried to intervene.
Judge Nancy Abudu dissented. She argued that the facility's very existence depended on federal involvement, that it would never have been built if not for the federal government's request. Abudu wrote:
"The facility would not, and could not, have been built and used as an immigration detention center without the federal defendants' request."
She pressed further, arguing that the nature of immigration enforcement itself proves federal control:
"The evidence of federal control perhaps is most apparent when we acknowledge that immigration remains uniquely and exclusively within the federal government's domain."
Abudu's argument has a surface appeal. Immigration enforcement is, of course, a federal responsibility. But the majority drew a line between the policy function, detaining illegal immigrants, and the construction and control of the physical facility. Florida built it, Florida runs the land, and Florida paid for it. The majority was unwilling to let the subject matter of what happens inside the building override the question of who built and controls it.
It is worth noting that federal appeals courts have repeatedly checked lower-court judges who have attempted to obstruct Trump administration immigration actions on procedural or novel legal grounds.
The case now returns to Judge Williams for further litigation. The environmental groups say they are not done. Eve Samples, executive director of Friends of the Everglades, said in a statement that the groups would continue pursuing the case.
"This fight is far from over. Alligator Alcatraz was hastily erected in one of the most fragile ecosystems in the country without the most basic environmental review at immense human and ecological cost."
That framing, "immense human and ecological cost", signals the litigation strategy going forward. The groups will likely try to establish federal control through other evidence or argue that the reimbursement arrangement changes the calculus. But with the 11th Circuit's reasoning now on the record, that road gets steeper.
Florida Attorney General James Uthmeier framed the ruling as a comprehensive victory, noting that the appeals court "not only blocked Judge Williams' order to close Alligator Alcatraz, but they blocked her from proceeding with the case until the appeal is complete." DeSantis himself said after the earlier stay was granted: "The mission continues on immigration enforcement."
Meanwhile, some of the legal fights surrounding the facility have extended beyond environmental law. Lawyer Katherine Blankenship, representing two migrants detained at the center, said in a court declaration earlier this month that guards severely beat and pepper-sprayed detainees, causing injuries to their heads, shoulders, and wrists.
"The officers beat several people during this incident and broke another detained individual's wrist."
Those allegations remain unresolved and are separate from the environmental case. But they suggest the facility will remain a magnet for legal challenges from multiple directions, even as the core question of whether it can operate has now been answered in Florida's favor.
The broader trend is hard to miss. Appellate courts have repeatedly cleared obstacles that lower-court judges placed in the path of Trump-backed initiatives, from immigration enforcement to executive construction projects.
Strip away the legal jargon and the case comes down to something simple. Florida's governor saw a need, built a facility with state resources on state land, and offered it in service of federal immigration enforcement. Environmental groups tried to shut it down by arguing that its federal purpose made it a federal project. The appeals court said no.
The AP confirmed the appellate majority's core finding: the facility was constructed, controlled, and funded by Florida, not the federal government. That factual record made the legal question relatively straightforward, whatever one thinks of the policy.
There is a pattern here that conservative observers have noted across multiple fronts. District judges, often in favorable jurisdictions, issue sweeping orders to halt executive action. Appellate courts review the record and reverse. The cycle repeats. It happened with deportation flight contempt proceedings, and it happened here.
The environmental groups will keep litigating. The facility will keep operating. And the people who actually have to live with the consequences of an unsecured border, the taxpayers, the border communities, the lawful residents, will keep waiting for the legal system to stop being used as a tool to obstruct enforcement of the laws already on the books.
