A Louisiana Subpoena to Produce Documents, Information, or Objects in a Criminal Case is a legal document issued by a court that requires a witness to appear at a certain time and location and to present certain documents, information, or objects for use in a criminal trial. There are two primary types of Louisiana Subpoenas to Produce Documents, Information, or Objects in a Criminal Case: a witness subpoena and a subpoena duces tecum. A witness subpoena requires a witness to appear in court to testify about what they know or have seen related to the criminal case. A subpoena duces tecum requires a witness to produce specific documents, records, or other objects that may be relevant to the case. Both types of subpoenas are issued by a judge or magistrate and must be served to the witness in order for them to be legally binding.
