What is a subpoena?

A subpoena is a legal document issued by a court or an authority that commands an individual to appear at a legal proceeding, such as a trial or deposition, or to produce certain documents or evidence related to a case. It serves to ensure that the necessary parties are present in court and that important information or evidence is made available to assist in the judicial process.

The other options represent different legal concepts. A negotiated agreement to resolve charges refers to a plea deal, which involves agreement between the defendant and the prosecution to resolve a case without going to trial. Conditional release from prison pertains to parole, where an inmate is released but must abide by certain conditions. Advisement of rights before custodial interrogation relates to the Miranda rights, which inform individuals of their rights when they are taken into custody. Each of these options addresses different aspects of legal proceedings and rights but does not accurately describe a subpoena.
