R.I. Gen. Laws § 12-19.2-3
In all cases in which the defendant pleads guilty or nolo contendere to an offense for which the penalty of life imprisonment without parole may be imposed pursuant to § 11-23-2 or 11-23-2.1, and in which the attorney general has recommended to the court in writing within twenty (20) days of the date of the arraignment that such a sentence be imposed, the court shall conduct a presentence hearing. At the hearing, the court shall permit the attorney general and the defense to present additional evidence relevant to a determination of the sentence to be imposed as provided for in § 12-19.2-4. After hearing evidence and argument relating to the presence or absence of aggravating and mitigating factors, the court shall, in its discretion, sentence the defendant to either life imprisonment without parole or life imprisonment. If the trial court is reversed on appeal because of error only in the presentence hearing, the new proceedings before the trial court which may be ordered shall pertain only to the issue of sentencing.
