U.S. judge says Florida can't ban cruise ship's 'vaccine passport' program

Aug 8 (Reuters) - A U.S. judge has allowed Norwegian Cruise Line Holdings Ltd. (NCLH.N)todemand that passengers show written proof of coronavirus vaccination before they board a ship, dealing a major blow to Florida Governor Ron DeSantis's effort to ban "vaccine passports."

In a preliminary ruling issued on Sunday, U.S. District Judge Kathleen Williams in Miami said Norwegian would likely prevail on its argument that the "vaccine passport" ban, signed into law by DeSantis in May, jeopardizes public health and is an unconstitutional infringement on Norwegian's rights.

The judge blocked DeSantis from enforcing the law against Norwegian, allowing the cruise ship operator to proceed with a plan to resume port activity in Miami on Aug. 15. Violations of the law could have triggered a penalty of $5,000 per passenger, potentially adding up to millions of dollars per cruise.

Raymond Treadwill, a lawyer for DeSantis, did not immediately respond to a request for comment.
