Dispossession by purchaser

(1) Where any person, other than the certificate-debtor, is dispossessed by the purchaser of immovable property which has been sold in execution of a certificate he may make an application to the Certificate Officer complaining of such dispossession. (2) The Certificate Officer shall thereupon fix a day for investigating the matter and shall summon the party against whom the application is made to appear and answer the same. No irregularity in publishing or conducting the sale of movable property shall vitiate the sale; but any person sustaining substantial injury by reason of such irregularity at the hand of any other person may institute a suit in a Civil Court against him for compensation, or if such other person is the purchaser, for the recovery of the specific property and for compensation in default of such recovery.
