QUO MINUS. The name of a writ. In England, when the king's debtor is sued in the court of the exchequer, he may sue out a writ of quo minus, in which he suggests that he is the king's debtor, and that the defendant has done him the injury or damage complained of, quo minus sufficiens existit, by which he is less able to pay the king's debt. This was originally requisite in order to give jurisdiction to the court of exchequer, but now this suggestion is a mere form. 3 Bl. Com. 46.
