Any county officer upon whom any duties devolve under the revenue laws of this state, who willfully neglects or refuses to perform any such duty, may be removed from office in the manner prescribed by law. When proceedings are commenced to remove such officer, the county commissioners, or in case such officer be a commissioner, then the district judge, may suspend such officer from his powers and duties under the revenue laws, and appoint a competent person in his place until a proper tribunal has either removed or acquitted such suspended officer. Any act relating to the appraisal of property, the assessment of property, the levy or collection of property taxes, or the sale of property for nonpayment of property taxes, performed by any such temporary officer, is valid and of the same force and effect as if performed by a duly qualified officer, elected to such office; provided, that such temporary officer has been bonded, as is required of persons duly elected to such office.
