Gaspar Manuel Sebastian filed the habeas petition seeking an injunction to stop his removal and immediate release from ICE custody. Sebastian challenged his detention by ICE and named multiple government officials as defendants, including Associate Director Marcos Charles, Attorney General Pamela Bondi, and Sheriff David Hardin.

U.S. District Judge Kathryn Kimball Mizelle ruled that Sebastian's deportation rendered his case moot, writing that "since [Plaintiff] already has been released from custody, his prayer for relief has been satisfied." The judge found that Sebastian's petition challenged only his detention, not the validity of his removal order or anything else, and he showed no continuing injury from his prior detention that the court could remedy.

Sebastian had sought immediate release from ICE custody through his habeas petition. The case proceeded through the Middle District of Florida's Fort Myers Division before the judge ultimately determined federal jurisdiction could not be sustained given the changed circumstances.

The ruling reflects established precedent that habeas petitions typically become moot once the petitioner is released from custody, unless they can show collateral consequences or the case falls under narrow exceptions like being "capable of repetition, yet evading review." Immigration attorneys will be watching for similar challenges as deportation proceedings continue to move through the courts.
