Other forms: subpoenas
A subpoena is an order telling you that you must appear in court. Serve a subpoena, issue a subpoena, ignore a subpoena.
Ignoring one is contempt of court and can mean arrest, which is the whole force of the thing. There are two kinds: one to appear and one to produce documents. The name is Latin for under penalty — the opening words of the old writ.
