After saying last month that it was blocking a controversial education measure from the November ballot, the Florida Supreme Court has released details of the ruling that show sharp differences about a proposal that one justice said would have brought a “monumental” change to the state constitution.

The justices, in a 4-3 decision, said the proposed constitutional amendment had “defective” ballot wording that would not inform voters of the measure’s “true meaning and ramifications.” The ruling centered on how the proposal would have affected the creation of charter schools, a hot-button issue in Florida’s education system.
