Writ of Quominus
The writ of quominus, or writ of quo minus, was a writ and legal fiction which allowed the Court of Exchequer to obtain a jurisdiction over cases normally brought in the Court of Common Pleas. The Exchequer was tasked with collecting the King's revenue, and the legal fiction worked by having the plaintiff in a debt case claim that he was a debtor to the king, and that the defendant's debt prevented him paying the King. As such, the defendant would be arrested, and the case heard by the Exchequer. The writ's predecessors were in use from at least 1230, and it was in common (albeit strict) use during the 16th century. The use continued into the 19th century, until all original writs were abolished in 1883. (Source:

The Court of Exchequer's main task was collecting royal revenues and taxes, partially through ensuring that debts to The Crown were paid.[1] It soon developed the ability to hear "common" cases, usually heard by the Court of Common Pleas, and did so through the writ of quominus. The origins of the writ are unknown, although some academics link it to a process through which a claimant could bring a claim jointly with the King or in part payment towards his debt to the King, in cases where the King had an interest.[2] The earliest record of a similar writ is 1230, although not with the quo minus wording.[3] The use was similar to that of the Bill of Middlesex, a similar legal fiction used by the Court of King's Bench; where a plaintiff claims money from a defendant for payment of a debt, the plaintiff would claim to be a debtor to the King, unable to pay his money to the King because of the defendant's debt.
