Rule 18.1. Trial by Jury

(a) By Jury The number of jurors required to try a case and render a verdict is provided by law.

(b) Waiver

(1) Generally The defendant may waive the right to a trial by jury if the State and the court consent. If the State and the court agree, a defendant also may waive the right to have a jury determine aggravation or the penalty in a capital case.

(2) Voluntariness Before accepting a defendant's waiver of a jury trial, the court must address the defendant personally, inform the defendant of the defendant's right to a jury trial, and determine that the defendant's waiver is knowing, voluntary, and intelligent.

(3) Form of Waiver A defendant's waiver of a jury trial must be in writing or on the record in open court.

(4) Withdrawal of Waiver With the court's permission, a defendant may withdraw a waiver of jury trial, but a defendant may not withdraw a waiver after the court begins taking evidence.
