The following describes a written order from a court directed to a peace officer, or to some other person specifically named, commanding that a person be placed under arrest:

The correct choice is a warrant, which is a written order issued by a court that authorizes law enforcement officers to arrest a specific individual. This legal document provides the necessary authority to detain someone based on probable cause that they have committed a crime.

Warrants are crucial in the legal system as they protect individual rights while allowing law enforcement to act upon credible evidence. They ensure that an arrest is not made arbitrarily and that there is judicial oversight in the process. The standard procedure requires law enforcement to provide evidence to a judge who then examines it before issuing the warrant.

The other options serve distinct legal purposes. A writ of habeas corpus is a court order that requires a person holding someone in custody to bring that person to court to determine the legality of their detention. A summons is typically an order to appear in court, usually in civil cases, rather than to arrest. A subpoena commands a person to testify or produce evidence in a legal proceeding but does not pertain to arresting individuals. Each of these other legal documents serves important functions, but they do not involve the authority to arrest a person.
