Bond of subdealer of milk.

(b) Such bond shall be in an amount not exceeding double the value of the total amount of milk so received or purchased by such subdealer during any one month of the year preceding the requirement thereof and shall be filed within ten days after notice of requirement. In any case in which the subdealer did not receive or purchase milk from processing dealers during at least six months of the year preceding such requirement, the commissioner shall determine the amount of the bond in a reasonable sum which shall not exceed double the value of the total amount of milk which it appears probable that such subdealer will receive or purchase from processing dealers during any one month of the year succeeding the requirement of such bond. The amount of the bond so required may be revised within six months after the filing thereof. (c) Upon default under any condition of such bond, the commissioner may give reasonable notice to processing dealers to file verified claims, fixing a reasonable time within which such claims shall be filed. The commissioner shall examine each claim so filed and shall determine and certify the amount due thereon. He may bring an action upon the bond and, for the purpose of such action, the certificate of the amount due shall be prima facie of the facts therein stated. If the recovery upon the bond is not sufficient to pay all claims filed and established, the amount recovered shall be prorated among the claimants.
