a) The sale deed Ex B-2 dated 11.12.1959 executed by Chellammal in favour of appellant cannot be brushed aside without evidence to show that Chellammal had no right to alienate the property. The records taken for evidence reveals that Chellammal who is the mother of Venkataraman has sold the property under a registered document as early as 11.12.1959. Later for the debts of her son Vekataraman, along with other properties, this property has also been brought to sale. In the revenue sale held in the year 1964 her grand son Narayanasamy has purchased it. The inclusion of a property in revenue auction which was already alienated by the mother itself not valid and proper. The purchaser of the property in the auction sale is none other than the grand son of Chellammal. The property has been brought to sale for the debt of the father and the auction purchaser was the debtor's son. Later, he has released it to his father and brother. So eventually the property is transferred within the family members ignoring the fact that one of the properties i.e. item 17 of the A schedule brought for revenue sale was already sold by Chellammal, as early as 1959. So no title could pass on to Narayanasamy in respect of this property though he has purchased it in revenue sale, since the debtor venkataraman himself had no title on the day when the property was brought to sale. Just because, the appellant was signatory to the later release deed executed by Narayanasamy, it will not make the earlier sale deed void. The witness to the document is only for the execution of the document and not for the truthfulness of its content. In short, the covenants found in the document will not bind the witness. Witness role is restricted to execution of the document and not further. Therefore the finding of the lower appellate court in respect of item 17 of the property is set at naught.
