(4) If the defendant's guilt was determined by plea of guilty or by decision of the trial court sitting without a jury, or if a retrial of the special sentencing proceeding is necessary for any reason including but not limited to a mistrial in a previous special sentencing proceeding or as a consequence of a remand from an appellate court, the trial court shall impanel a jury of twelve persons plus whatever alternate jurors the trial court deems necessary. The defense and prosecution shall each be allowed to peremptorily challenge twelve jurors.
