A New Jersey Deposition Subpoena in a Criminal Case (AO 90) is a legal document issued by a court in the state of New Jersey that orders a person to appear in court and give testimony in a criminal case. This type of subpoena is often used by prosecutors to compel witnesses to testify about their knowledge of the case. There are two types of New Jersey Deposition Subpoena in a Criminal Case (AO 90): 1) A Witness Subpoena, which requires a person to appear and give testimony in court; and 2) A Subpoena Ducks Cecum, which requires a person to produce documents or other tangible evidence related to the case. Both types of subpoenas must be served personally upon the person being subpoenaed and must include the date, time, and location of the hearing.
