The Florida Supreme Court overturned a state statute that allowed a jury to impose a death sentence by a 10-2 vote. In order to impose the death penalty, the Court ruled that a jury most be unanimous. It may not be an obviously major decision, but these jury voting rules are enormously important, especially with how we know prosecutors abuse peremptory strikes to keep minorities off the jury. If the rules on such peremptory-strike abuses are so hard to enforce, (or just as accurately, if courts are unwilling to enforce those rules), then this unanimity rule is at least a back-up check on prosecutors.
