Specific Relief Act, 1963
37. Temporary and perpetual injunctions
(1) Temporary in junctions are such as are to continue until a specific time, or until the further order of the court, and they may be granted at any stage of a suit, and are regulated by the Code of Civil Procedure, 1908.
(2) A perpetual injunction can only be granted by the decree made at the hearing and upon the merits of the suit; the defendant is thereby perpetually enjoined from, the assertion of a right, or from the commission of an act, which could be contrary to the rights of the plaintiff.
