With a hearing scheduled next week, attorneys for Gov. Ron DeSantis' administration are asking a federal judge to reject arguments by Norwegian Cruise Line Holdings that a state ban on so-called vaccine passports is unconstitutional.

The state's attorneys on Tuesday filed a 28-page document contending that U.S. District Judge Kathleen Williams should turn down Norwegian's request for a preliminary injunction against the vaccine-passport ban.

The ban, a priority of DeSantis, prevents businesses from requiring customers to show proof of vaccination against COVID-19. Norwegian filed the lawsuit July 13, saying the ban would prevent it from carrying out a plan to require passengers to be vaccinated.

In the document Tuesday, the state's attorneys wrote that Florida has exercised its "sovereign power" in banning vaccine passports and refuted the cruise line's constitutional arguments.

But in the lawsuit, Norwegian said it is scheduled to resume sailing Aug. 15 and that "one anomalous, misguided intrusion [the vaccine passport ban] threatens to spoil NCLH's [Norwegian Cruise Line Holdings'] careful planning and force it to cancel or hobble upcoming cruises, thereby imperiling and impairing passengers' experiences and inflicting irreparable harm of vast dimensions."
