What document compels an individual to appear in court or supply evidence?

A subpoena is a legal document that compels an individual to appear in court as a witness or to produce evidence for a legal proceeding. This tool is essential in the legal process as it ensures that witnesses can be called to testify and that relevant documents or evidence can be secured for the case. The court has the authority to issue a subpoena to gather necessary information to get a fuller understanding of the matters at hand.

In contrast, a case brief is a summary of a legal case that helps attorneys and students organize and understand case law, but it does not have the power to compel attendance or evidence. A warrant is a document issued by a judge that authorizes law enforcement to take a specific action, such as arresting a person or searching a location, but it does not serve the function of requiring an individual to appear in court or provide evidence. An indictment is a formal accusation that initiates a criminal case, charging an individual with a crime, but again, it does not compel attendance or evidence like a subpoena does. Thus, the proper mechanism for requiring someone to appear or provide evidence in court is indeed a subpoena.
