Sec 13-4037. Power of supreme court to correct and reduce sentence upon appeal by defendant

A. Upon an appeal by the defendant either from a judgment of conviction or from sentence, if an illegal sentence has been imposed upon a lawful verdict or finding of guilty by the trial court, the supreme court shall correct the sentence to correspond to the verdict or finding. The sentence as corrected shall be enforced by the court from which the appeal was taken.

B. Upon an appeal from the judgment or from the sentence on the ground that it is excessive, the court shall have the power to reduce the extent or duration of the punishment imposed, if, in its opinion, the conviction is proper, but the punishment imposed is greater than under the circumstances of the case ought to be inflicted. In such a case, the supreme court shall impose any legal sentence, not more severe than that originally imposed, which in its opinion is proper. Such sentence shall be enforced by the court from which the appeal was taken.
