Injunction

A court decision commanding or preventing a specific act, such as an order that an abusive spouse stay away from the other spouse or that a logging company not cut down first-growth trees. Courts grant injunctions to prevent harm--often irreparable harm--as distinguished from most court decisions, which are designed to provide a remedy for harm that has already occurred. Injunctions can be temporary, pending a consideration of the issue later at trial (these are called interlocutory decrees or preliminary injunctions). Judges can also issue permanent injunctions at the end of trials.
