Injunction

n. court order ordering someone to do or refrain from doing something (Law); command, order

An injunction is an equitable remedy in the form of a court order, whereby a party is required to do, or to refrain from doing, certain acts. The party that fails to adhere to the injunction faces civil or criminal penalties and may have to pay damages or accept sanctions for failing to follow the court's order. In some cases, breaches of injunctions are considered serious criminal offences that merit arrest and possible prison sentences.
