Mandatory injunction :

Section 39 dealing with mandatory injunctions states that when to prevent the breach of an obligation, it is necessary to compel the performance of certain acts which the Court is capable of enforcing, the Court may in its discretion grant an injunction to prevent the breach complained of, and also to compel performance of the requisite acts. For example, A builds a house with eaves projecting over B’s land, B may sue for an injunction to pull down so much of the eaves as so projecting over his land.

According to Section 40, the plaintiff in a suit for perpetual injunction under Section 38 or mandatory injunction under Section 39, may claim damages either in addition to, or in substitution for such injunction and the Court, may, if it thinks fit, award such damages.
