A permanent injunction is a court order that requires a person or entity to stop doing a specific action permanently. This type of injunction is typically issued after a trial, where the court determines that the plaintiff has proven their case and that the harm caused by the action is significant enough to warrant a long-term solution. Once a permanent injunction is granted, it remains in effect indefinitely unless the court modifies or dissolves it. Violating a permanent injunction can lead to legal penalties, including fines or other enforcement actions, ensuring compliance with the court's decision.
