Injunction vs. consummated acts

It is a well-established rule that consummated acts can no longer be restrained by injunction.[1] When the acts sought to be prevented by injunction or prohibition have already been performed or completed prior to the filing of the injunction suit, nothing more can be enjoined or restrained;[2] a writ of injunction then becomes moot and academic,[3] and the court, by mere issuance of the writ, can no longer stop or undo the act. To do so would violate the sole purpose of a prohibitive injunction, that is, to preserve the status quo.
