(a) Time for Filing in Noncapital Cases. In cases in which the state does not seek the death penalty, a motion for new trial or a motion in arrest of judgment, or both, may be made, either orally in open court or in writing and filed with the clerk’s office, within 10 days after the rendition of the verdict or the finding of the court. A timely motion may be amended to state new grounds without leave of court prior to expiration of the 10-day period and in the discretion of the court at any other time before the motion is determined.
(b) Time for Filing in Capital Cases Where the Death Penalty Is an Issue. A motion for new trial or a motion in arrest of judgment, or both, or for a new penalty phase hearing may be made within 10 days after written final judgment of conviction and sentence of life imprisonment or death is filed. The motion may address grounds which arose in the guilt phase and the penalty phase of the trial. Separate motions for the guilt phase and the penalty phase may be filed. The motion or motions may be amended without leave of court prior to the expiration of the 10-day period, and in the discretion of the court, at any other time before the motion is determined.
(c) Oral Motions. When the defendant has been found guilty by a jury or by the court, the motion may be dictated into the record, if a court reporter is present, and may be argued immediately after the return of the verdict or the finding of the court. The court may immediately rule on the motion.
(d) Written Motions. The motion may be in writing, filed with the clerk; it shall state the grounds on which it is based. A copy of a written motion shall be served on the prosecuting attorney. When the court sets a time for the hearing thereon, the clerk may notify counsel for the respective parties or the attorney for the defendant may serve notice of hearing on the prosecuting attorney.
(e) Custody Pending Motion. A defendant who is not already at liberty on bail shall remain in custody and not be allowed liberty on bail unless the court, on good cause shown if the offense for which the defendant is convicted is bailable, permits the defendant to be released on bail until the court disposes of the motion. If the defendant is already at liberty on bail that is deemed by the court to be good and sufficient, the court may permit the defendant to continue at large on such bail until the motion for new trial is heard and the court disposes of the motion.
