The Orange school board votes to join a proposed lawsuit over Florida’s new education law, becoming the 10th county in the state to do so.

The Orange County School Board voted Tuesday to join a proposed lawsuit that will challenge the constitutionality of parts of a controversial education law the Florida Legislature passed this spring.

Orange’s board, which voted 8-0 to join the legal fight, is the 10th district to do so, deciding to enter the multi-school-district effort about an hour after the Polk County School Board, said Woody Rodriguez, the board’s attorney.

Board members are convinced the law, HB 7069, has unconstitutional provisions related to charter schools, publicly funded institutions run by private groups. “This is not about whether we are pro-charter or anti-charter,” said Chairman Bill Sublette. “This is about upholding the constitution of the state of Florida.”

Orange has more than 30 charter schools — which need board approval to open — now operating, he added.

But he and others said the new law unjustly requires school boards to share some local taxes with charters and allows some “schools of hope” charters to open without local board approval and hire uncertified teachers, among other issues.

Orange’s board plans to send a letter to legislators saying if they rescind those portions of the law, Orange’s board will withdraw from any legal action.

“We’re willing to work with you, but we want to see some changes,” board member Joie Cadle said. “And if we have to, we’re willing to fight this out in court.”

Orange educators said the money they have pledged so far — $25,000 — likely will come from the district’s marketing budget, funded by internet sales, not taxpayer money.
