US appeals court invalidates injunction against Alligator Alcatraz detention site

The 11th Circuit reversed Judge Kathleen Williams's August order, allowing the Florida Everglades facility, which has held thousands of undocumented migrants since last summer, to keep operating.
Judges said plaintiffs, including the Miccosukee Tribe and environmental groups, had not shown federal control and that the injunction partly breached limits on blocking immigration enforcement; the case returns to Williams.
The plaintiffs say they will continue challenging the site over alleged environmental harm and lack of a required review, citing threats to sacred tribal lands, wildlife and Everglades water resources.

Alligator Alcatraz Detention Center: Environmental, Cultural, and Legal Crisis Following Appeals Court Reversal
Overview
In April 2026, the US Court of Appeals overturned a lower court injunction against Florida's Alligator Alcatraz immigration detention facility, accepting the state's claim of control and allowing the facility to reopen. This ruling set a precedent letting state-run detention centers bypass federal environmental laws like NEPA and ESA, exposing a gap in environmental enforcement. The facility, built without required federal environmental reviews, threatens the fragile Everglades ecosystem and the cultural survival of the Miccosukee Tribe, who have taken legal action to protect their ancestral lands. Meanwhile, Florida's pursuit of nearly $1.5 billion in federal funding faces challenges, creating financial pressure amid ongoing environmental and legal battles.
