in effect18-1.3-1302. Imposition of sentences in class 1 felonies for crimes committed on or after July 1, 1988, and prior to September 20, 1991 - appellate review - applicability. (1) (a) Upon conviction of guilt of a defendant of a class 1 felony, the trial court shall conduct a separate sentencing hearing to determine whether the defendant should be sentenced to death or life imprisonment, unless the defendant was under the age of eighteen years at the time of the commission of the offense, in which case the defendant shall be sentenced to life imprisonment. The hearing shall be conducted by the trial judge before the trial jury as soon as practicable. Alternate jurors shall not be excused from the case prior to submission of the issue of guilt to the trial jury and shall remain separately sequestered until a verdict is entered by the trial jury. If the verdict of the trial jury is that the defendant is guilty of a class 1 felony, the alternate jurors shall sit as alternate jurors on the issue of punishment. If, for any reason satisfactory to the court, any member or members of the trial jury are excused from participation in the sentencing hearing, the trial judge shall replace such juror or jurors with an alternate juror or jurors. If a trial jury was waived or if the defendant pleaded guilty, the hearing shall be conducted before the trial judge.
(b) All admissible evidence presented by either the prosecuting attorney or the defendant that the court deems relevant to the nature of the crime, and the character, background, and history of the defendant, including any evidence presented in the guilt phase of the trial, and any matters relating to any of the aggravating or mitigating factors enumerated in subsections (4) and (5) of this section may be presented. Any such evidence which the court deems to have probative value may be received, as long as each party is given an opportunity to rebut such evidence. The prosecuting attorney and the defendant or the defendant's counsel shall be permitted to present arguments for or against a sentence of death. For offenses committed before July 1, 1985, the jury shall be instructed that life imprisonment means life without the possibility of parole for twenty calendar years. For offenses committed on or after July 1, 1985, the jury shall be instructed that life imprisonment means life without the possibility of parole for forty calendar years.
(c) Both the prosecuting attorney and the defense shall notify each other of the names and addresses of any witnesses to be called in the sentencing hearing and the subject matter of such testimony. Such discovery shall be provided within a reasonable amount of time as determined by order of the court and shall be provided not less than twenty-four hours prior to the commencement of the sentencing hearing. Unless good cause is shown, noncompliance with this paragraph (c) shall result in the exclusion of such evidence without further sanction.
(d) The burden of proof as to the aggravating factors enumerated in subsection (5) of this section shall be beyond a reasonable doubt. There shall be no burden of proof as to proving or disproving mitigating factors.
(2) (a) After hearing all the evidence and arguments of the prosecuting attorney and the defendant, the jury shall deliberate and render a verdict based upon the following considerations:
(I) Whether at least one aggravating factor has been proved as enumerated in subsection (5) of this section;
(II) Whether sufficient mitigating factors exist which outweigh any aggravating factor or factors found to exist; and
(III) Based on the considerations in subparagraphs (I) and (II) of this paragraph (a), whether the defendant should be sentenced to death or life imprisonment.

(I) Whether at least one aggravating factor has been proved as enumerated in subsection (5) of this section;
(II) Whether sufficient mitigating factors exist which outweigh any aggravating factor or factors found to exist; and
(III) Based on the considerations in subparagraphs (I) and (II) of this paragraph (a), whether the defendant should be sentenced to death or life imprisonment.
(b) (I) In the event that no aggravating factors are found to exist as enumerated in subsection (5) of this section, the jury shall render a verdict of life imprisonment, and the court shall sentence the defendant to life imprisonment.
(II) The jury shall not render a verdict of death unless it finds and specifies in writing that:
(A) At least one aggravating factor has been proved; and
(B) There are insufficient mitigating factors to outweigh the aggravating factor or factors that were proved.
(c) In the event that the jury's verdict is to sentence to death, such verdict shall be unanimous and shall be binding upon the court unless the court determines, and sets forth in writing the basis and reasons for such determination, that the verdict of the jury is clearly erroneous as contrary to the weight of the evidence, in which case the court shall sentence the defendant to life imprisonment.
(d) If the jury's verdict is not unanimous, the jury shall be discharged, and the court shall sentence the defendant to life imprisonment.
(3) In all cases where the sentencing hearing is held before the court alone, the court shall determine whether the defendant should be sentenced to death or life imprisonment in the same manner in which a jury determines its verdict under paragraphs (a) and (b) of subsection (2) of this section. The sentence of the court shall be supported by specific written findings of fact based upon the circumstances as set forth in subsections (4) and (5) of this section and upon the records of the trial and the sentencing hearing.
