What is the legal term for a writ that directs a peace officer to bring a witness before a court?

The correct term for a writ that directs a peace officer to bring a witness before a court is known as a subpoena. A subpoena is a legal instrument that compels an individual to appear and testify before a court or other legal proceeding. It is essential for ensuring that witnesses can provide their testimony and evidence necessary for the legal process.

While a summons is used to notify a party about a legal action against them and requires them to appear in court, it does not specifically direct a peace officer to bring a witness. An attachment is generally a legal order to seize property or assets to satisfy a judgment, and a writ of mandamus is an order from a court to a lower court or other government officials to perform a duty they are legally obligated to complete. Each of these terms serves different legal functions, which is why subpoena is the appropriate choice for directing a peace officer to bring a witness to court.
