An injunction is an equitable remedy in the form of a court order that requires a party to do or refrain from doing certain acts. A party that fails to comply with an injunction faces criminal or civil penalties and may have to pay damages or accept sanctions. In some cases, breaches of injunctions are considered serious criminal offenses that merit arrest and possible prison sentences.
Another definition: 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.
