A liberal judge ordered Florida's Alligator Alcatraz detention center shut down – and the 11th Circuit just handed her a humiliating reversal.
Now the activists are back at square one, and illegal aliens stay right where DeSantis put them.
And the ruling didn't just keep the facility open – it blocked the judge from touching the case at all until a full appeal plays out.
The Left's Legal Strategy Just Failed in Court
Environmental groups thought they had a clever move.
They sued to shut down Florida's Everglades detention facility using the National Environmental Policy Act – federal environmental review law – as their weapon.
U.S. District Judge Kathleen Williams in Miami bought it.
Last August, she issued a preliminary injunction ordering the facility to start winding down within 60 days and blocking new detainees.
Florida Attorney General James Uthmeier appealed immediately.
This week, the 11th U.S. Circuit Court of Appeals reversed her – 2 to 1.
Chief Circuit Judge William Pryor, a George W. Bush appointee, wrote the majority opinion and made it simple.
"Florida, not federal, officials constructed the facility," Pryor wrote. "They control the land and 'entirely' built the facility at state expense."

NEPA applies to federal action – and Florida's build gave the activists nothing to grab onto.
Federal reimbursement had not yet arrived when Williams issued her injunction – a fact the majority specifically noted.
DeSantis posted one response after the ruling came down: another activist court decision overturned on appeal.
Uthmeier went further.
The 11th Circuit didn't just block Williams' shutdown order – according to Just the News, it blocked her from advancing the case at all until the full appeal is resolved.
Why the Activists Keep Losing
This was never about alligators or wetlands.
Environmental law was just the crowbar they picked up after everything else failed.
Democrats tried blocking DHS funding for detention capacity.

They tried shaming Republican governors out of participating in immigration enforcement.
When Trump toured Alligator Alcatraz on July 1, 2025 – the day before the first detainees arrived – and told reporters the swamp was basically a natural security perimeter, the left had nothing to counter it.
So they found a sympathetic district judge in Miami and sued under NEPA.
The 11th Circuit just showed what that strategy was worth.
Here's why it keeps failing: the legal framework that allows states to build and operate detention facilities under federal immigration authority is solid.
The Trump administration asked Florida to create a detention capacity.
Florida used emergency powers, acquired the Dade-Collier Training and Transition Airport site, and built the facility in eight days.
That speed and state-level ownership is exactly what made it legally bulletproof against the NEPA attack.
The dissenting judge, Nancy Abudu, argued immigration is a federal function and the federal government can't escape responsibility just because a state holds the deed.
That's a philosophical argument – and philosophy doesn't run immigration detention centers.
Florida holds the land, writes the checks, and employs the guards.
The majority stuck to those facts.
What This Ruling Means for Every State
DeSantis has already built a second facility – Baker Correctional Institution in northern Florida now functions as a second immigration detention center.
He's not stopping.
And after this ruling, he doesn't have to worry about NEPA challenges stopping him either.
Here's what just happened in legal terms: the 11th Circuit confirmed that state-built, state-funded, state-operated immigration detention facilities sit outside the reach of federal environmental review law.
Other Republican governors were watching this case closely.
Texas Gov. Greg Abbott already built 160 miles of border wall on state land during the Biden years – and the Trump reconciliation package now includes $13.5 billion in federal reimbursement for it.
The pattern is the same: states act first, states absorb the legal challenges, and the courts confirm the states were right.
Activist groups like Friends of the Everglades and the Center for Biological Diversity say the fight isn't over.
They're right – it isn't over.
But it just got a lot harder.
The case goes back to Judge Williams for further proceedings while Alligator Alcatraz stays fully open.
Every detainee housed there while the activists' appeal plays out is one more illegal alien off Florida streets – exactly what DeSantis built it for.
