Amends the Unified Code of Corrections. Provides if the defendant has been found guilty by a judge or jury after a trial, the prosecutor shall file with the court at the sentencing hearing a verified written statement signed by the prosecutor setting forth the prosecutor's final offer, if any, of any specified sentence and any charge to be dismissed or not charged in a plea discussion in exchange for a plea of guilty from the defendant and waiver of his or her right to trial. Also provides in any sentence, a defendant shall not be punished by the imposition of a heavier or greater sentence merely because he or she exercises his or her constitutional right to be tried before an impartial judge or jury.
