An injunction is an order from the court to refrain from certain conduct or to perform some certain act(s). It is a form of equitable relief. In contrast, legal relief usually comes in the form of money damages to compensate someone for an injury. Equitable relief is typically appropriate when monetary relief would be inadequate.
Assuming a case is suited for an injunction, there are three traditional phrases of injunctive relief: 1) a temporary restraining order granted against a defendant with or without notice or hearing; 2) a temporary or preliminary injunction granted following notice and hearing; and 3) a permanent injunction following the final disposition of the merits of the case. Rule 92.02(c)(3) authorizes the trial court to consolidate the hearings on the preliminary and permanent injunctions. There are numerous rules required at every stage of this proceeding (e.g., bond, notice requirements, etc.) and thus great care should be exercised in requesting injunctive relief.
