Washington Waiver of Speedy Trial is a legal procedure in which a defendant in a criminal case agrees to waive their right to a speedy trial and opts to have the case tried at a later date. It is used to allow both the defense and the prosecution to prepare adequately for the trial. There are two types of Washington Waiver of Speedy Trial: voluntary and involuntary. A voluntary waiver occurs when the defendant signs a written waiver form, expressly waiving their right to a speedy trial. An involuntary waiver occurs when the defendant does not appear in court on the trial date, or when the prosecution and the court mutually agree to postpone the trial. In either case, the defendant must be informed of the consequences of waiving their right to a speedy trial.
