Peremptory writ of mandamus

A peremptory writ of mandamus (also peremptory writ of mandate or simply peremptory mandamus) is an absolute and unqualified writ (a formal written command) to the defendant to do the act in question. It is issued when the defendant defaults on, or fails to show sufficient cause in answer to, an alternative mandamus. It is one of the three types of a mandamus.
