An order of the court requiring a party to perform some act or refrain from some conduct so as to respect the rights of another.

A court order requiring someone to stop doing a specified act (negative injunction) or requiring the doing of a positive act (mandatory injunction). Injunctions can be granted pre-trial (interim or interlocutory injunctions) or after a full trial (final injunction). Disobedience can result in proceedings for contempt of court, leading to a fine or even imprisonment.

A discretionary court order to do or not to do something. An injunction may be mandatory (requiring a positive course of action), prohibitory (requiring the cessation of some activity), interlocutory (an interim injunction before trial), and quia timet (issued before any damage has been suffered).

A court order restraining a party from the performance of some act (prohibitory injunction), or requiring the performance of some act (mandatory injunction). Injunctions may be permanent or temporary.

Court order commonly referred to as an extraordinary remedy because it is an order to stop a defendant from continuing the conduct complained of or to compel the defendant to take some specific action before a full trial on the merits of the matter has been conducted. Injunctions in a labour context are requested to stop union picket lines from blockading ingress to and egress from an employer’s premises during a strike.
