One group, describing itself as the “framers” of an education constitutional amendment, was largely appointed by former Democratic Gov. Lawton Chiles. Another group was appointed by 1990s-era Republican legislative leaders. But two decades after the groups served together on the 1997-1998 Florida Constitution Revision Commission, they are clashing in the state Supreme Court. The root of the clash is an amendment that the Constitution Revision Commission placed on the 1998 ballot that spelled out a duty for the state to provide a high-quality system of public schools.
