A more thorough explanation: A subpoena in blank is a legal document issued by a court that commands a person to appear at a specific time and place, but does not specify the reason for their appearance. This type of subpoena is often used when the exact nature of the testimony or evidence required cannot be determined in advance. The reason for the appearance will be revealed to the person once they are present.
