Ann. § 21-6617(e), and amendments thereto, or requested pursuant to Kan. Stat. Ann. § 21-6617(a) or (b), and amendments thereto, the defendant shall be sentenced to life without the possibility of parole.

(2) (A) Except as provided in subsection (a)(2)(B), a defendant convicted of attempt to commit the crime of capital murder shall be sentenced to imprisonment for life and shall not be eligible for probation or suspension, modification or reduction of sentence.

(B) The provisions of subsection (a)(2)(A) requiring the court to impose a mandatory minimum term of imprisonment of 25 years shall not apply if the court finds the defendant, because of the defendant’s criminal history classification, would be subject to presumptive imprisonment pursuant to the sentencing guidelines grid for nondrug crimes and the sentencing range would exceed 300 months if the sentence established for a severity level 1 crime was imposed. In such case, the defendant is required to serve a mandatory minimum term equal to the sentence established for a severity level 1 crime pursuant to the sentencing range. The defendant shall not be eligible for parole prior to serving such mandatory minimum term of imprisonment, and such mandatory minimum term of imprisonment shall not be reduced by the application of good time credits.

In such case, the defendant is required to serve a mandatory minimum term equal to the sentence established for a severity level 1 crime pursuant to the sentencing range. The defendant shall not be eligible for parole prior to serving such mandatory minimum term of imprisonment, and such mandatory minimum term of imprisonment shall not be reduced by the application of good time credits. No other sentence shall be permitted.

Ann. § 21-6623, and amendments thereto, unless the sentencing judge finds substantial and compelling reasons, following a review of mitigating circumstances, to impose the sentence specified in subsection (c)(2).

(B) The provisions of subsection (c)(1)(A) requiring the court to impose the mandatory minimum term of imprisonment required by Kan. Stat. Ann. § 21-6623, and amendments thereto, shall not apply if the court finds the defendant, because of the defendant’s criminal history classification, would be subject to presumptive imprisonment pursuant to the sentencing guidelines grid for nondrug crimes and the sentencing range would exceed 600 months if the sentence established for a severity level 1 crime was imposed.

In addition, the defendant shall not be eligible for parole prior to serving 25 years’ imprisonment, and such 25 years’ imprisonment shall not be reduced by the application of good time credits. No other sentence shall be permitted.

(B) The provisions of subsection (c)(2)(A) requiring the court to impose a mandatory minimum term of imprisonment of 25 years shall not apply if the court finds the defendant, because of the defendant’s criminal history classification, would be subject to presumptive imprisonment pursuant to the sentencing guidelines grid for nondrug crimes and the sentencing range would exceed 300 months if the sentence established for a severity level 1 crime was imposed.

No other sentence shall be permitted.

(d) The provisions of this subsection shall apply only to the crime of murder in the first degree based upon the finding of premeditated murder committed on or after September 6, 2013, but prior to July 1, 2014.

(1) If a defendant is convicted of murder in the first degree based upon the finding of premeditated murder, upon reasonable notice by the prosecuting attorney, the court shall determine, in accordance with this subsection, whether the defendant shall be required to serve a mandatory minimum term of imprisonment of 50 years or sentenced as otherwise provided by law.

(2) The court shall conduct a separate proceeding following the determination of the defendant’s guilt for the jury to determine whether one or more aggravating circumstances exist. Such proceeding shall be conducted by the court before a jury as soon as practicable. If any person who served on the trial jury is unable to serve on the jury for the proceeding, the court shall substitute an alternate juror who has been impaneled for the trial jury. If there are insufficient alternate jurors to replace trial jurors who are unable to serve at the proceeding, the court may conduct such proceeding before a jury which may have 12 or less jurors, but at no time less than six jurors. If the jury has been discharged prior to the proceeding, a new jury shall be impaneled. Any decision of the jury regarding the existence of an aggravating circumstance shall be beyond a reasonable doubt. Jury selection procedures, qualifications of jurors and grounds for exemption or challenge of prospective jurors in criminal trials shall be applicable to the selection of such jury. The jury at the proceeding may be waived in the manner provided by Kan. Stat. Ann. § 22-3403, and amendments thereto, for waiver of a trial jury. If the jury at the proceeding has been waived, such proceeding shall be conducted by the court.

(3) In the proceeding, evidence may be presented concerning any matter relating to any of the aggravating circumstances enumerated in Kan. Stat. Ann. § 21-6624, and amendments thereto. Only such evidence of aggravating circumstances as the prosecuting attorney has made known to the defendant prior to the proceeding shall be admissible and no evidence secured in violation of the constitution of the United States or of the state of Kansas shall be admissible. No testimony by the defendant at the time of the proceeding shall be admissible against the defendant at any subsequent criminal proceeding. At the conclusion of the evidentiary presentation, the court shall allow the parties a reasonable period of time in which to present oral argument.

(4) At the conclusion of the evidentiary portion of the proceeding, the court shall provide oral and written instructions to the jury to guide its deliberations. If the prosecuting attorney relies on Kan. Stat. Ann. § 21-6624(a), and amendments thereto, as an aggravating circumstance, and the court finds that one or more of the defendant’s prior convictions satisfy such subsection, the jury shall be instructed that a certified journal entry of a prior conviction is presumed to prove the existence of such prior conviction or convictions beyond a reasonable doubt.

(5) If, by unanimous vote, the jury finds beyond a reasonable doubt that one or more of the aggravating circumstances enumerated in Kan. Stat. Ann. § 21-6624, and amendments thereto, exist, the jury shall designate, in writing, signed by the foreman of the jury, the statutory aggravating circumstances which it found. If, after a reasonable time for deliberation, the jury is unable to reach a unanimous sentencing decision, the court shall dismiss the jury and the defendant shall be sentenced as provided by law. In nonjury cases, the court shall designate, in writing, the specific circumstance or circumstances which the court found beyond a reasonable doubt.

(6) If one or more of the aggravating circumstances enumerated in Kan. Stat. Ann. § 21-6624, and amendments thereto, are found to exist beyond a reasonable doubt pursuant to this subsection, the defendant shall be sentenced pursuant to Kan. Stat. Ann. § 21-6623, and amendments thereto, unless the sentencing judge finds substantial and compelling reasons, following a review of mitigating circumstances, to impose the sentence specified in this paragraph. If the sentencing judge does not impose the mandatory minimum term of imprisonment required by Kan. Stat. Ann. § 21-6623, and amendments thereto, the judge shall state on the record at the time of sentencing the substantial and compelling reasons therefor, and the defendant shall be sentenced to imprisonment for life and shall not be eligible for probation or suspension, modification or reduction of sentence. In addition, the defendant shall not be eligible for parole prior to serving 25 years’ imprisonment, and such 25 years’ imprisonment shall not be reduced by the application of good time credits. No other sentence shall be permitted.

(e) The provisions of this subsection shall apply only to the crime of murder in the first degree based upon the finding of premeditated murder committed prior to September 6, 2013.

(1) If a defendant is convicted of murder in the first degree based upon the finding of premeditated murder, upon reasonable notice by the prosecuting attorney, the court shall conduct a separate sentencing proceeding in accordance with this subsection to determine whether the defendant shall be required to serve a mandatory minimum term of imprisonment of 40 years or for crimes committed on and after July 1, 1999, a mandatory minimum term of imprisonment of 50 years or sentenced as otherwise provided by law.

(2) The sentencing proceeding shall be conducted by the court before a jury as soon as practicable. If the trial jury has been discharged prior to sentencing, a new jury shall be impaneled. Any decision to impose a mandatory minimum term of imprisonment of 40 or 50 years shall be by a unanimous jury. Jury selection procedures, qualifications of jurors and grounds for exemption or challenge of prospective jurors in criminal trials shall be applicable to the selection of such jury. The jury at the sentencing proceeding may be waived in the manner provided by Kan. Stat. Ann. § 22-3403, and amendments thereto, for waiver of a trial jury. If the jury at the sentencing proceeding has been waived, such proceeding shall be conducted by the court.

(3) In the sentencing proceeding, evidence may be presented concerning any matter that the court deems relevant to the question of sentence and shall include matters relating to any of the aggravating circumstances enumerated in Kan. Stat. Ann. § 21-6624, and amendments thereto, or for crimes committed prior to July 1, 2011, Kan. Stat. Ann. § 21-4636, prior to its repeal, and any mitigating circumstances. Any such evidence which the court deems to have probative value may be received regardless of its admissibility under the rules of evidence, provided that the defendant is accorded a fair opportunity to rebut any hearsay statements. Only such evidence of aggravating circumstances as the prosecuting attorney has made known to the defendant prior to the sentencing proceeding shall be admissible and no evidence secured in violation of the constitution of the United States or of the state of Kansas shall be admissible. Only such evidence of mitigating circumstances subject to discovery pursuant to Kan. Stat. Ann. § 22-3212, and amendments thereto, that the defendant has made known to the prosecuting attorney prior to the sentencing proceeding shall be admissible. No testimony by the defendant at the time of sentencing shall be admissible against the defendant at any subsequent criminal proceeding. At the conclusion of the evidentiary presentation, the court shall allow the parties a reasonable period of time in which to present oral argument.

(4) At the conclusion of the evidentiary portion of the sentencing proceeding, the court shall provide oral and written instructions to the jury to guide its deliberations. If the prosecuting attorney relies on Kan. Stat. Ann. § 21-6624(a), and amendments thereto, or for crimes committed prior to July 1, 2011, Kan. Stat. Ann. § 21-4636(a), prior to its repeal, as an aggravating circumstance, and the court finds that one or more of the defendant’s prior convictions satisfy such subsection, the jury shall be instructed that a certified journal entry of a prior conviction is presumed to prove the existence of such prior conviction or convictions beyond a reasonable doubt.

(5) If, by unanimous vote, the jury finds beyond a reasonable doubt that one or more of the aggravating circumstances enumerated in Kan. Stat. Ann. § 21-6624, and amendments thereto, or for crimes committed prior to July 1, 2011, Kan. Stat. Ann. § 21-4636, prior to its repeal, exist and, further, that the existence of such aggravating circumstances is not outweighed by any mitigating circumstances which are found to exist, the defendant shall be sentenced pursuant to Kan. Stat. Ann. § 21-6623, and amendments thereto; otherwise, the defendant shall be sentenced as provided by law. The sentencing jury shall designate, in writing, signed by the foreman of the jury, the statutory aggravating circumstances which it found. The trier of fact may make the findings required by this subsection for the purpose of determining whether to sentence a defendant pursuant to Kan. Stat. Ann. § 21-6623, and amendments thereto, notwithstanding contrary findings made by the jury or court pursuant to Kan. Stat. Ann. § 21-6617(e), and amendments thereto, for the purpose of determining whether to sentence such defendant to death. If, after a reasonable time for deliberation, the jury is unable to reach a unanimous sentencing decision, the court shall dismiss the jury and the defendant shall be sentenced as provided by law. In nonjury cases, the court shall designate in writing the specific circumstance or circumstances which the court found beyond a reasonable doubt.

(f) The amendments to subsection (e) by chapter 1 of the 2013 Session Laws of Kansas (Special Session):

(1) Establish a procedural rule for sentencing proceedings, and as such shall be construed and applied retroactively to all crimes committed prior to the effective date of this act, except as provided further in this subsection; (2) shall not apply to cases in which the defendant’s conviction and sentence were final prior to June 17, 2013, unless the conviction or sentence has been vacated in a collateral proceeding, including, but not limited to, Kan. Stat. Ann. §§ 22-3504 or 60-1507, and amendments thereto; and (3) shall apply only in sentencing proceedings otherwise authorized by law.

(g) Notwithstanding the provisions of subsection (h), for all cases on appeal on or after September 6, 2013, if a sentence imposed under this section, prior to amendment by chapter 1 of the 2013 Session Laws of Kansas (Special Session), or under Kan. Stat. Ann. § 21-4635, prior to its repeal, is vacated for any reason other than sufficiency of the evidence as to all aggravating circumstances, resentencing shall be required under this section, as amended by chapter 1 of the 2013 Session Laws of Kansas (Special Session), unless the prosecuting attorney chooses not to pursue such a sentence.

(h) In the event any sentence imposed under this section is held to be unconstitutional, the court having jurisdiction over a person previously sentenced shall cause such person to be brought before the court and shall sentence such person to the maximum term of imprisonment otherwise provided by law.

(i) If any provision or provisions of this section or the application thereof to any person or circumstance is held invalid, the invalidity shall not affect other provisions or applications of this section which can be given effect without the invalid provision or provisions or application, and to this end the provisions of this section are severable.
