mandamus

1. (law) A common law prerogative writ that compels a court or government officer to perform mandatory or purely ministerial duties correctly.Examples: "I admit to all my learned friends that a Mandamus does not issue where there is another course of proceeding by which the thing can be effected; but I again state to your Lordships, that if in this case a Mandamus must not issue, there is no other proceeding that can be adopted."; "And then it was moved that the court would grant a mandamus to the delegates to admit the bishop's allegations: and it was compared to the cases where they grant mandamuses to compel the granting of probates of wills or letters of administration."; "A mandamus is a writ commanding the execution of an act, where otherwise justice would be obstructed, or the king's charter neglected, issuing regularly only in cases relating to the public and the government; and is therefore termed […] a prerogative writ."countableuncountable
