When doubt or differences arise as to the correctness of the net or gross weight or measure of any amount or part of any commodity for which a State certificate of weights and measures has been issued by a public weighmaster, the owner, agent, or consignee may, upon complaint to the Commissioner of Agriculture, have the amount or part thereof reweighed by the Department of Agriculture or a public weighmaster designated by it, upon depositing a sufficient sum of money to defray the actual cost of reweighing with the Commissioner of Agriculture or his representative. If, on reweighing, a difference from the original certified weight is discovered as the result of fraud, carelessness, or faulty apparatus, the cost of reweighing shall be borne by the public weighmaster responsible for the issuance of the erroneous certificate.
