Mandamus

Mandamus ("we command"), a high prerogative writ issued in the Queen's name from the High Court of Justice. It is in the nature of a command, and may be addressed to any person, corporation, or inferior Court of Judicature within the kingdom, requiring them to do something therein specified which appertains to their office, and which the court holds to be consonant to right and justice. It is used mainly for public purposes and to enforce performance of public rights or duties. It, however, is also sometimes used to enforce private rights when they are withheld by public officers.
