Specific Releif Act, 1963; Section 19- In view of clause (b) of Section 19, the defendants who are claiming under the sale deeds executed after the execution of the suit agreement can be subjected to a decree of specific performance as the suit agreement can be enforced specifically against such defendants unless they are bona-fide purchasers without the notice of the original contract. When, in a given case, the defendants, who are subsequent purchasers, fail to prove that they entered into the sale deed in good faith and without notice of the suit agreement, in view of Section 19(b), a decree for specific performance can be passed against such defendants. Therefore, in such a case where Section 19(b) is applicable, under the decree of specific performance, the subsequent purchasers can be directed to execute the sale deed along with the original vendor. There is no necessity to pray for the cancellation of the subsequent sale deeds. (Para 16)
