A writ of prohibition, in the United States, is an official legal document drafted and issued by a supreme court or superior court to a judge presiding over a suit in an inferior court. The writ of prohibition mandates the inferior court to cease any action over the case because it may not fall within that inferior court's jurisdiction. The document is also issued at times when it is deemed that an inferior court is acting outside the normal rules and procedures in the examination of a case. In another instance, the document is issued at times when an inferior court is deemed headed towards defeating a legal right.
