Defending a 2017 law that set regulations for the state’s medical marijuana industry, Florida Department of Health attorneys have asked an appeals court to overturn a circuit judge’s ruling that they say “injected confusion and uncertainty” into the licensing of marijuana firms.

The closely watched case centers on whether a law passed during a 2017 special legislative session violated a constitutional amendment that broadly legalized medical marijuana. Leon County Circuit Judge Charles Dodson in October found the 2017 law unconstitutional and issued a temporary injunction requiring state health officials to begin registering the plaintiff, Tampa-based Florigrown, and other medical-marijuana firms to do business.
