Through posts, any prudent person can guess that some link is missing and query is cryptic.
Now you are coming with facts one by one. Like blaming collecting Banker, your dues, NPA status, pending before DRT etc.,which were not disclosed in your first post, though these facts are material.
I am sure that the payee, you are referring to may also be a Bank.
The following was your first query
The blank signed cheques was kept with staff who posted it via speed post to bank in collusion with officials of the bank, However not knowing knowing account number, he filled completely different account number, bank deposited the cheque, and the bank of accused returned the cheque citing the endorsement " Account number doesn't match with cheque number"
Will the provision of NI Act will be applicable?
If the payee is a bank, they can establish consideration towards loan repayment.
