A virtual hearing in federal court in Miami was being held Monday on a lawsuit that was filed July 16. A new motion on the case was filed Friday.

Lawyers who have shown up for bond hearings for “Alligator Alcatraz” detainees have been told that the immigration court doesn’t have jurisdiction over their clients, the attorneys wrote in court papers. The immigration attorneys demanded that federal and state officials identify an immigration court that has jurisdiction over the detainees and start accepting petitions for bond, claiming the detainees constitutional rights to due process are being violated.

“This is an unprecedented situation where hundreds of detainees are held incommunicado, with no ability to access the courts, under legal authority that has never been explained and may not exist,” the immigration attorneys wrote. “This is an unprecedented and disturbing situation.”

The lawsuit is the second one challenging “Alligator Alcatraz.” Environmental groups last month sued federal and state officials asking that the project built on an airstrip in the heart of the Florida Everglades be halted because the process didn’t follow state and federal environmental laws.

Critics have condemned the facility as a cruel and inhumane threat to the ecologically sensitive wetlands, while Florida Gov. Ron DeSantis and other Republican state officials have defended it as part of the state’s aggressive push to support President Donald Trump’s crackdown on illegal immigration.

U.S. Homeland Security Secretary Kristi Noem has praised Florida for coming forward with the idea, as the department looks to significantly expand its immigration detention capacity.
