This discussion concerns a specific performance case where a buyer filed a suit for specific performance after the seller failed to execute a registered sale deed. The seller subsequently sold the land to third parties, who were then added as defendants. The core questions revolve around whether a specific performance decree can still be granted, what actions to take if a decree is passed and the property is no longer with the original seller, and if the buyer has the right to cancel the sale deed. The advice touches upon the doctrine of 'lis pendens' and the importance of impleading the new purchasers as necessary parties.
