(1) When sentence is imposed upon any person following a conviction of any felony, other than a class 1 felony in which a death sentence is automatically reviewed pursuant to section 18-1.3-1201 (6), 18-1.3-1302 (6), or 18-1.4-102 (6), the person convicted shall have the right to one appellate review of the propriety of the sentence, having regard to the nature of the offense, the character of the offender, and the public interest, and the manner in which the sentence was imposed, including the sufficiency and accuracy of the information on which it was based; except that, if the sentence is within a range agreed upon by the parties pursuant to a plea agreement, the defendant shall not have the right of appellate review of the propriety of the sentence. The procedures to be employed in the review shall be as provided by supreme court rule.

(2) No appellate court shall review any sentence which is imposed unless, within forty-nine days from the date of the imposition of sentence, a written notice is filed in the trial court to the effect that review of the sentence will be sought; said notice must state the grounds upon which it is based.

(2.1) and (2.2) Repealed.

(3) The reviewing court shall have power to affirm the sentence under review, substitute for the sentence under review any penalty that was open to the sentencing court other than granting probation or other conditional release, or remand the case for any further proceedings that could have been conducted prior to the imposition of the sentence under review, and for resentencing on the basis of such further proceedings. No sentence in excess of the one originally imposed shall be given unless matters of aggravation in addition to those known to the court at the time of the original sentence are brought to the attention of the court during the hearing conducted under this section. If the court imposes a sentence in excess of the one first given, it shall specifically identify the additional aggravating facts considered by it in imposing the increased sentence.
