“Where there is a sale of the same property in favour of a prior and subsequent transferee and the subsequent transferee has, under the conveyance outstanding in his favour, paid the purchase-money to the vendor, then in a suit for specific performance brought by the prior transferee, in case he succeeds, the question arises as to the proper form of decree in such a case. The practice of the Courts in India has not been uniform and three distinct lines of thought emerge. According to one point of view, the proper form of decree is to declare the subsequent purchase void as against the prior transferee and direct conveyance by the vendor alone. A second considers that both vendor and vendee should join, while a third would limit execution of the conveyance to the subsequent purchaser alone. According to the Supreme Court, the proper form of decree is to direct specific performance of the contract between the vendor and the prior transferee and direct the subsequent transferee to join in the conveyance so as to pass on the title which resides in him to the prior transferee. He does not join in any special covenants made between the prior transferee and his vendor; all he does is to pass on his title to the prior transferee.”
