A remedy in the form of a court order addressed to a particular person that either prohibits him from doing or continuing to do a certain act (a prohibitory injunction) or orders him to carry out a certain act (a mandatory injunction). The remedy is discretionary and will be granted only if the court considers it just and convenient to do so; it will not be granted if damages would be a sufficient remedy.
Injunctions are often needed urgently. A temporary injunction (an interim injunction) may therefore be granted at a special hearing pending the outcome of the main hearing of the case. If it is granted, the claimant must undertake to compensate the defendant for any damage he has suffered by the grant of the injunction if the defendant is successful in the main action. If judgment is given for the claimant in the main action, a perpetual injunction may be granted. A person who fails to abide by the terms of an injunction may be guilty of contempt of court. See also freezing injunction; quia timet.
