Pennsylvania Waiver of Trial By Jury is a legal document that allows a defendant to forgo their right to a jury trial in a criminal case in the state of Pennsylvania. It is also known as a 'waiver of jury trials', 'jury waiver', or 'waiver of jury verdict'. The waiver must be approved by the presiding judge in the case and all parties must agree before it can be accepted. There are two types of Pennsylvania Waiver of Trial By Jury. The first is 'express waiver', which is a written document signed by all parties involved in the case that states their agreement to waive their right to a jury trial. The second is 'implied waiver', which occurs when a defendant takes action that implies they are waiving their right to a jury trial, such as participating in a bench trial or agreeing to a plea bargain. Both types of waivers must be approved by the court.
