The Specific Relief Act, 1963
§37 — Temporary and perpetual injunctions
(1) Temporary injunctions 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 (5 of 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 would be contrary to the rights of the plaintiff.
