In a Execution Petition , order was made by the court under R 54 O 21 CPC on 18.08.2011 for attachment of Immovable Property of Judgement Debtor and attending the court by him on 22.09.2011 and this order was also sent to Process Server/Amin/Nazir for executing the same well in time, but the date of 22.09.2011 and 19.11.2011 has passed off, but nothing was done by him except sending back to executing court by remarking does not have time. Now another same order has been issued to him dated 20.12.2011. The original decree was passed ex-party. I have read that until order of execution petition is executed, it is null and void against the stranger i.e. purchaser under order 38 rule 10. But my question is whether the Judgement Debtor can himself take an excuse that at the time of selling the property, I was not aware of the decision of the court, as it was ex party decree or he will be presumed to know the order of ex-party decree in general and specially when at initial level he appeared in the court after getting summon and contested the suit until in a matter cost of Rs. 5000/- was imposed on him, that was not deposited by him, and afterwards he remained absent.
