MIAMI (CBSMiami) – An appeals court Wednesday dismissed a case filed by the Miami-Dade County School Board that challenged an initial Florida Department of Health rule aimed at preventing schools from requiring students to wear masks.

A panel of the 3rd District Court of Appeal said the challenge was moot because the Department of Health last month repealed the initial rule and issued a new version.
