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.

Florida court decisions have applied the ban more broadly, however, requiring a new look at any juvenile serving life — even if the sentence was optional or included the possibility of parole. A state law passed three years ago said those terms are to be automatically reviewed by a circuit court judge after 15, 20 or 25 years served, depending on the crime. The state Supreme Court ruled that the reviews should be extended to those former teen offenders who were already in prison before the law was changed.
