Insuranceopedia explains Writ
The person who writes and issues a writ is often a court judge or someone with equivalent power and responsibility.
There are many forms of writ. A warrant is a writ that instructs a police officer to arrest a suspect of a crime. A subpoena orders a person to appear in court, even against their will.
A writ can also be issued to question the validity of a court action. A higher court can issue a writ that reviews the decisions of a lower court, such as the writ of habeas corpus, which reviews the constitutional soundness of criminal convictions.
