A federal judge in Miami is set to hear closing arguments Wednesday regarding whether to indefinitely suspend construction at an immigrant detention facility in the Florida Everglades, known as 'Alligator Alcatraz.' The facility, designed to hold up to 3,000 detainees in temporary tent structures, has sparked controversy due to environmental concerns.

US District Judge Kathleen Williams ordered a two-week halt on new construction last Thursday as she considers whether the center violates environmental laws.

Environmental groups and the Miccosukee Tribe argue that the facility threatens environmentally sensitive wetlands and could reverse years of environmental restoration efforts.

The National Environmental Policy Act, which requires federal agencies to assess the environmental impacts of major construction projects, has been cited by plaintiffs as a basis for halting operations.

The state and federal government maintain that the construction and operation of the facility fall under state jurisdiction.

Witnesses have testified about potential threats to the Everglades ecosystem, including increased water runoff and harm to endangered species.

Amy Castaneda, the Miccosukee Tribe’s water resource director, expressed concerns over nutrient runoff affecting tribal lands and wildlife habitats.

Marcel Bozas, director of the tribe's fish and wildlife department, highlighted the impact on hunting and fishing activities for cultural and subsistence purposes.

The facility has faced additional legal challenges related to detainees' rights, including claims of restricted access to lawyers and the absence of charges.

A second immigration detention center is reportedly being planned at a Florida National Guard training center in north Florida.
