Then this case might serve as a precedent in any med.cannabis defence in court, something you could cite in other courts of that county, then of that state's, then federal... in that case I believe the supreme court is obligated to issue an opinion on law enforcement, which can lead to medical excuse becoming a valid excuse in courts across the country. I am not a lawyer - could be wrong - anyone competent here to answer this question?
It never went to court, therefore it's not precedent for anything. The next time they bust a grower, they'll just pretend it never happened, likely get away with it, too.
