Of course you will not get a unanimous reply
Different lawyers will have different views
That is how law works
Otherwise there would never be 2 disputing parties before a Court whose issue is to be resolved
Coming to your follow up query-
A borrower or guarantor who has defaulted in repayment can participate in the auction in which his property is being sold. There is no restriction against the same.
But then if you think logically if the bank allows the defaulter borrower to participate in the auction then its running a risk that the auction sale will most probably not be completed since if the borrower could not pay the loan of the bank, how would he pay the sale price of the property? So bank would permit the borrower to bid for the auction knowing fully well that ultimately it's an act by the borrower to delay or avoid the sale of his property
On a second thought the OTS was altogether a new contract. If the full amount was not paid under the OTS then the bank cannot again approach DRT but it has to file a money recovery suit against the borrower and guarantor. It would be a commercial summary suit.
The loan transaction between the bank and your father as guarantor and the borrower came to an end when the OTS was floated by the bank and acted upon. If there is any money still left to be paid under the OTS then bank cannot invoke Sarfaesi act again and go to DRT
This defense you can take in the hearing before the Recovery officer
Also I think there are certain properties which are exempted from attachment under s. 60 of civil procedure code. Let me check that and get back.
