Suit to recover possession of or to set aside sale of immovable property where notice of certificate not served

Notwithstanding anything herein before contained, a sale of immovable property in execution of a certificate shall not be void on the ground that the notice required by section 6 has not been served, but a suit may be brought in a Civil Court to recover the possession of such property or to set aside such sale on the ground that such notice has not been served and that the plaintiff had sustained substantial injury by reason of such irregularity. Provided that no such suit shall be entertained-(a) if instituted more than one year from the date on which possession of the property was delivered to the purchaser, or (b) if the certificate-debtor has made appearance in the certificate proceeding or has applied to the Certificate Officer under section 22 or section 23 to set aside the sale, or (c) if instituted after one year from the date of having the fact of delivery of the property by the plaintiff in case the fact of such delivery was not known to the plaintiff.
