In view of the above, the law can   be summarised to the effect that the recovery of the public dues must be made   strictly in accrodance with the procedure prescrived by law. The   liability of a surety is co-extensive with that of principal debtor. In case   there are more than one surety the liability is to be divided equally among the   sureties for unpaid amount of loan. Once   the sale has been confirmed it cannot be set aside unless   a fundamental procedural error has occured or sale certificate had been   obtained by misrepresentation or fraud. 
  The authority is duty bound to decide whether debt can be   satisfied by sale of part of the property. Valuation is different from minimum   price and must be done fairly.
