Sale deed was to be executed upto 27.07.1999. Puran Chand always remained ready and willing to perform his part of the contract, but the defendants committed breach thereof. They tried to alienate the suit land whereupon suit for permanent injunction was instituted, but the same was got dismissed as infructuous, after date stipulated for execution of the sale deed expired. On 27.07.1999, the date stipulated for execution of the sale deed, Puran Chand went to the office of Sub-Registrar to get the sale deed executed in terms of the agreement, but defendant Nos.1 and 2 did not turn up. On the contrary, defendant No.1 has sold 8 kanals land out of the suit land to defendant Nos.3 to 7 vide registered sale deed dated 29.10.1999 which is null and void. Puran Chand died on 28.09.1999. Consequently, the suit was filed by his legal heirs for possession of the suit land by specific performance of the impugned agreement and also for seeking declaration that aforesaid sale deed dated 29.10.1999 is null and void.
