One would assume that state law trumps local board decrees.
Moreover "legislative entrenchment" is a kind of logical fallacy that no court recognizes. No one can bind a constitutionally elected legislature from taking any future action simply by decree. Moreover, Reedy Creek isn't even a law-making body, its an administrative one.
Its a childish manuever which a court should slap-down immediately. Of course, depends on if its a leftist/activist judge, of course.....
Doesn’t even need to go to court. Under regular order this is subject to the review of a state board which would take a very dim very of this maneuver no matter who attempted it.
