What is a writ issued by a court commanding a peace officer to bring a witness to court?

The appropriate answer is a subpoena, which is a legal document that orders an individual to appear in court as a witness or to produce evidence in a legal proceeding. A subpoena serves as a formal command issued by the court and is directed at the specific person designated as a witness. The role of a peace officer regarding a subpoena would typically involve ensuring that the witness receives the document and understands the requirement to appear in court.

A writ of certiorari is a different type of legal order that directs a lower court to deliver its records to a higher court for review. This is primarily used in appellate courts to examine the decisions made by lower courts.

A writ of attachment is an order issued by a court to seize a person's property to secure a judgment, which is not related to bringing witnesses to court.

A court order is a general term that refers to any directive issued by a judge. While it can command various actions, it does not specifically pertain to the summoning of witnesses like a subpoena does.

Understanding these distinctions helps clarify why a subpoena is the correct answer in the context of commands issued to bring a witness to court.
