Florida has roughly 600 inmates whose life sentences for homicide are potentially affected by court rulings mandating a second look at the punishment of juvenile offenders, but most still await a shot at resentencing.

Two U.S. Supreme Court rulings, the latest last year, concluded that it’s unconstitutional to impose mandatory life sentences without a chance for parole on juveniles convicted of homicide. The justices ruled that such sentences amount to cruel and unusual punishment and that courts must recognize teens’ incomplete brain development and potential for rehabilitation.
