R.I. Fam. R. Crim. P. 33
On motion of the defendant the court may grant a new trial to the defendant if required in the interest of justice. If trial was by the court without a jury, the court on motion of a defendant for a new trial may vacate the judgment, take additional testimony, and direct the entry of a new judgment. A motion for a new trial based on newly discovered evidence may be made only within three (3) years after the entry of judgment by the court, but if an appeal is pending, the court may grant the motion only on remand of the case. A motion for a new trial based on any other grounds shall be made within ten (10) days after the verdict or finding of guilty or within such further time as the court may fix during the ten-day period. A copy of the motion for a new trial shall be filed with the clerk of the court.
