On Sunday, District Court Judge Kathleen Williams issued a preliminary injunction that blocks the state of Florida from enforcing a law that would have blocked cruise lines from requiring their passengers provide COVID-19 vaccine records.

While this is a temporary injunction that only applies to a single company, the ruling indicates that the law violates two separate constitutional protections, and provides a roadmap for any other company that is interested in contesting it. In addition, the same legal logic may apply to many similar statutes and executive orders adopted elsewhere in the US.
