Sunday, the judge said Florida failed to “provide a valid evidentiary, factual, or legal predicate” for banning requirements that passengers prove they’ve been vaccinated. Norwegian has shown that suspending the requirement will jeopardize public health, potentially causing “super-spreader” events wherever passengers disembark, she wrote.

The CDC lost on appeal, but then made its guidelines non-binding, and all cruise lines operating in Florida have agreed to keep following the CDC’s instructions on a voluntary basis, the judge wrote.
