Whenever the owner of any tract, lot, parcel or piece of land is deprived of his title thereto, or to some portion thereof, or by reason of any suit in relation thereto is put to expense, damages, costs or charges, by reason of the failure of the county collector to give proper credit for any taxes paid by him, or whenever any tract, parcel or lot of land shall have been assessed to two or more different persons and the entire tax shall have been paid by either of them, and the collector shall sell such land as delinquent on account of the nonpayment by the other party of the taxes assessed against him thereon, the party damaged by such sale, or his legal representatives, may, in an action against the officer by whose act or omission such damages have been caused, or upon his official bond, recover a judgment for the amount of all the damages, costs and charges to which such owner may have been subjected in consequence of such failure or such dereliction of duty, and in addition a ten percent penalty thereon.
