The court said Monday in a 4-3 vote it has rejected a request by Attorney General Sam Olens and a handful of charter schools who claimed the decision could throw Georgia's educational system into chaos.
The May ruling overturned a law that allowed the state to approve and fund charter schools over the objection of local school boards.
Since the court's ruling, the 16 commission schools have been scrambling in search of ways to keep their doors open. About 16,000 students could be affected.
Motions for reconsideration are rarely granted, and even charter school advocates called the move a "Hail Mary."
