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.
Our Founders' Warning: “Every government degenerates when trusted to the rulers of the people alone. The people themselves are its only safe depositories.” (Thomas Jefferson)
