G. At the penalty phase, the defendant and the state may present any evidence that is relevant to the determination of whether there is mitigation that is sufficiently substantial to call for leniency. In order for the trier of fact to make this determination, the state may present any evidence that demonstrates that the defendant should not be shown leniency.

H. The trier of fact shall determine unanimously whether death is the appropriate sentence. If the trier of fact is a jury and the jury unanimously determines that the death penalty is not appropriate, the court shall determine whether to impose a sentence of life or natural life.

The new jury shall not retry the issue of the defendant’s guilt or the issue regarding any of the aggravating circumstances that the first jury found by unanimous verdict to be proved or not proved. If the new jury is unable to reach a unanimous verdict, the court shall impose a sentence of life or natural life on the defendant.
