Writs. We’ve all heard of them. There’s the writ of certiorari, the writ of habeas corpus, and the writ of mandamus, just to name a few. But what exactly is a writ and what does it do? Simply put, a writ is “an order issued by a legal authority with administrative or judicial powers, typically a court.” Historically, in the common law, writs were used to convey real property, grant privileges or rights, and to convey information. They were also written executive directives from the king, instruments by which the king could intervene into matters that were not resolved by feudal courts. Later, writs evolved, adopting a more judicial nature, acting as summonses or the initial documents in legal matters or as an order commanding a person to do something or refrain from doing something.
