Current with legislation signed by the governor on or before 3/6/2024
In a trial of all indictments, informations, complaints, and other proceedings before any court or magistrate, against persons charged with the commission of any crime, the person charged shall, at his own request, but not otherwise, be a competent witness. His failure to make such request does not create any presumption against him.
