Mandamus
（重定向自Mandatory order）
Mandamus is a judicial remedy in the form of an order from a superior court, to any government subordinate court, corporation, or public authority—to do (or forbear from doing) some specific act which that body is obliged under law to do (or refrain from doing)—and which is in the nature of public duty, and in certain cases one of a statutory duty. It cannot be issued to compel an authority to do something against statutory provision. For example, it cannot be used to force a lower court to reject or authorize applications that have been made, but if the court refuses to rule one way or the other then a mandamus can be used to order the court to rule on the applications.
