(a) Procedure in jury trials.--
(1) After a verdict of murder of the first degree is recorded and before the jury is discharged, the court shall conduct a separate sentencing hearing in which the jury shall determine whether the defendant shall be sentenced to death or life imprisonment.
(2) In the sentencing hearing, evidence concerning the victim and the impact that the death of the victim has had on the family of the victim is admissible. Additionally, evidence may be presented as to any other matter that the court deems relevant and admissible on the question of the sentence to be imposed. Evidence shall include matters relating to any of the aggravating or mitigating circumstances specified in subsections (d) and (e), and information concerning the victim and the impact that the death of the victim has had on the family of the victim. Evidence of aggravating circumstances shall be limited to those circumstances specified in subsection (d).
(3) After the presentation of evidence, the court shall permit counsel to present argument for or against the sentence of death. The court shall then instruct the jury in accordance with subsection (c).
(4) Failure of the jury to unanimously agree upon a sentence shall not impeach or in any way affect the guilty verdict previously recorded.
(b) Procedure in nonjury trials and guilty pleas.--If the defendant has waived a jury trial or pleaded guilty, the sentencing proceeding shall be conducted before a jury impaneled for that purpose unless waived by the defendant with the consent of the Commonwealth, in which case the trial judge shall hear the evidence and determine the penalty in the same manner as would a jury as provided in subsection (a).
(c) Instructions to jury.--
(1) Before the jury retires to consider the sentencing verdict, the court shall instruct the jury on the following matters:
(i) The aggravating circumstances specified in subsection (d) as to which there is some evidence.
(ii) The mitigating circumstances specified in subsection (e) as to which there is some evidence.
(iii) Aggravating circumstances must be proved by the Commonwealth beyond a reasonable doubt; mitigating circumstances must be proved by the defendant by a preponderance of the evidence.
(iv) The verdict must be a sentence of death if the jury unanimously finds at least one aggravating circumstance specified in subsection (d) and no mitigating circumstance or if the jury unanimously finds one or more aggravating circumstances which outweigh any mitigating circumstances. The verdict must be a sentence of life imprisonment in all other cases.
(v) The court may, in its discretion, discharge the jury if it is of the opinion that further deliberation will not result in a unanimous agreement as to the sentence, in which case the court shall sentence the defendant to life imprisonment.
(2) The court shall instruct the jury that if it finds at least one aggravating circumstance and at least one mitigating circumstance, it shall consider, in weighing the aggravating and mitigating circumstances, any evidence presented about the victim and about the impact of the murder on the victim's family. The court shall also instruct the jury on any other matter that may be just and proper under the circumstances.
