Waiver of Rule 32.1 Hearing is a process by which a person facing criminal charges can waive their right to a hearing under Arizona Rule of Criminal Procedure 32.1. This is a pre-trial hearing, where the judge determines if there is enough evidence to proceed to trial. Waiving this hearing means the person agrees to the facts presented by the prosecution, and they do not need to have a hearing. There are two types of waivers of Rule 32.1 Hearing: voluntary and involuntary. Voluntary waivers are requested by the defendant and are usually granted by the judge if they believe the accused has sufficient understanding of the charges and proceedings. Involuntary waivers are requested by the prosecution and are granted by the judge if the prosecution can prove the defendant is not competent to stand trial or if the defendant has previously waived the hearing.
