PROHIBITION
PROHIBITION, practice. The name of a writ issued by a superior court, directed to the judge and parties of a suit in an inferior court, commanding them to cease from the prosecution of the same, upon a suggestion that the cause originally, or some collateral matter arising therein, does not belong to that jurisdiction, but to the cognizance of some other court. 3 Bl. Com. 112; Com. Dig. h. t.; Bac. Ab. h. t. Saund. Index, h. t.; Vin. Ab. h. t.; 2 Sell. Pr. 308; Ayliffe's Parerg. 434; 2 Hen. Bl.
2. The writ of prohibition may also be issued when, having jurisdiction, the court has attempted to proceed by rules differing from those which ought to be observed; Bull. N. P. 219; or when, by the exercise of its jurisdiction, the inferior court would defeat a legal right. 2 Chit. Pr. 355.
