Common questions
Frequently Asked
5
What factors does a court weigh when deciding whether to grant a preliminary injunction?+
A court compares the threat of irreparable harm if the injunction is denied, the hardship an injunction would impose on the defendant, the plaintiff's likelihood of success on the merits, and the public interest. Additional equitable considerations include the nature of the interest at stake, the adequacy of money damages, any delay by the plaintiff, and the practicality of framing and enforcing the order.
Must a movant post security before a preliminary injunction issues?+
Yes. The court may issue a preliminary injunction only if the movant gives security in an amount the court considers proper to pay costs and damages sustained by any party found to have been wrongfully enjoined. The United States and its agencies are exempt from this requirement.
Can a preliminary injunction issue without notice to the adverse party?+
No. The court may issue a preliminary injunction only on notice to the adverse party. When an order is issued without notice, the motion for a preliminary injunction must be set for hearing at the earliest possible time and the party who obtained the order must proceed with the motion or the court must dissolve it.
How does a preliminary injunction differ from a temporary restraining order?+
A preliminary injunction requires notice to the adverse party and may last until the case is resolved or modified by the court. A temporary restraining order may issue without notice in exigent circumstances but expires after a short period, typically no more than fourteen days, unless extended for good cause.
Is a preliminary injunction automatically available whenever a continuing trespass or nuisance is alleged?+
No. Even when a plaintiff alleges a continuing trespass or nuisance, the court must conduct a comparative appraisal of irreparable harm, hardship, delay, likelihood of success, and public interests rather than granting relief as of right.
