In a significant legal development, the US Court of Appeals for the Eleventh Circuit decided on Thursday that the contentious migrant detention center in the Florida Everglades, dubbed "Alligator Alcatraz," can continue operations while a federal appeal is underway. This ruling overturns a preliminary injunction from August by the US District Court for the Southern District of Florida, which had paused the expansion of the facility citing the lack of a completed environmental impact report mandated by the National Environmental Policy Act (NEPA).

The appellate court's decision hinged on several critical assessments, including the likelihood of the federal defendants succeeding on the merits of the case and the potential for irreparable harm if the stay on the injunction were not granted. The court's order emphasized, “Our job is to balance the equities, as well as the overall public interest... the injuries facing the Defendants and the public are critical, immediate, and concrete.”

Key to the court's ruling was the interpretation of NEPA and its 2023 amendments, which clarify that only "major federal actions" require environmental impact reports. The court noted that the term “major federal action” excludes projects with minimal federal funding or involvement. Given that Florida funds the facility's operation and construction, the court concluded it does not constitute a "major federal action."

However, dissenting voices like Judge Adalberto Jordan highlighted ongoing claims by federal officials and Governor Ron DeSantis that the federal government may yet reimburse Florida for the facility, suggesting deeper federal involvement than acknowledged in the court’s majority opinion.

The legal challenge was initiated by environmental groups and the Miccosukee Tribe of Indians of Florida, who are worried about the detention center's impact on the nearby Big Cypress National Preserve. They argue that the facility threatens the local ecosystem, a concern that the initial injunction sought to address by halting expansion until an environmental review could be conducted.

Governor DeSantis’s declaration of a state of emergency in 2023 led to the swift establishment of the facility under the auspices of addressing a statewide immigration crisis. This emergency declaration expanded the powers of the Florida Division of Emergency Management, enabling rapid construction and operational decisions regarding "Alligator Alcatraz."

As this case continues to unfold, it highlights the ongoing tensions between state-level immigration enforcement strategies and federal environmental and immigration policies. The resolution of this case could set significant precedents regarding the balance of state and federal powers, the scope of environmental laws, and the management of migrant detention practices.
