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.
An injunction bond therefore might be required when an injunction has been issued, the court may order the injunction dissolved upon the purchase of a bond guaranteeing to pay, subject to the terms of the bond, such damages as the plaintiff may sustain as result of the performance of the act or acts originally enjoined.
When an injunction has been granted, the court may order the injunction dissolved upon the giving of a discharge injunction bond. In affect, to pay such damages as the plaintiff may sustain as a result of the performance of the act or acts originally enjoined, it being then the privilege of the defendant to proceed as if injunction had never been issued.
