From Section 4 of article 9:
(b) The school board shall operate, control and supervise all free public schools within the school district and determine the rate of school district taxes within the limits prescribed herein. Two or more school districts may operate and finance joint educational programs.
School boards do not operate, control nor do they supervise charter schools. Yes school districts are supposed to authorize them but they are generally forced to by other statues passed by the legislature or because the state board of education rubber stamps charter schools. Despite this fact many districts do fight. Unfortunately Duval is not one of them that does. Furthermore charters have their own non elected boards that do operate and control them.
From SECTION 1. Public education.—
From the League of Women voters: The court determined that charter schools were not common schools because they were not governed by the elected school boards. Moreover, the court ruled that using general funds for charters was illegal, given that charters are not common schools.
