In terms of justice, an injunction is a court’s order that requires a person to do or abstain from doing an act that is necessary and the absence of which would be contrary to good faith and good conscience. This provision statutory supports the Natural Justice and Equity. This arm of justice is aimed to restore the violated rights of a party, whereby monetary or compensatory damages are insufficient and also comes as an addition to another remedy. Temporary Injunctions are those which remain in force until specified time or until further orders. Such injunctions can be granted at any stage of the suit and are governed by Order 39 of the Code of Civil Procedure, 1908 rather than by Specific Relief Act, 1963 .(S 37(1))

Permanent Injunctions on the other hand, maybe granted, at the discretion of the court by the decree of the court after hearing the case .It remains in force for all time to come.( S 37(2))

Cases
In Agriculture Produce Market and Ors v/s Girdhar Bhai Ramjibhai and Ors. (1995) 5 SCC 468,it was observed that Injunction can only be granted only if the person seeking the injunction has a right capable of being enforced by the way of injunction.
