MIAMI (AP) — Norwegian Cruise Line is challenging a new Florida law that prevents cruise companies from requiring passengers to show proof of vaccination against the COVID-19 virus. The lawsuit, filed Tuesday in Miami federal court, contends that the law jeopardizes safe operation of cruise vessels by increasing risk of contracting the virus. Norwegian intends to restart cruises from Florida ports Aug. 15 with vaccinations required for all passengers. Norwegian wants a judge to lift the ban by Aug. 6. The law imposes a fine of $5,000 each time a cruise line mandates that a passenger provide vaccination proof.
