Washington Waiver of Preliminary Hearing is a procedure in which a defendant voluntarily waives the right to a preliminary hearing and requests that the case proceed directly to trial. A defendant may waive the right to a preliminary hearing in order to save time and money, or may do so because they feel confident that the case will go to trial. There are two types of Washington Waiver of Preliminary Hearing: a voluntary waiver and a court-ordered waiver. A voluntary waiver is when the defendant voluntarily waives their right to a preliminary hearing. A court-ordered waiver is when the court orders the defendant to waive their right to a preliminary hearing in order to move the case forward to trial. In both cases, the waiver must be signed by the defendant and approved by the court in order for it to take effect.
