Cal. Food & Agr. Code § 58934
In lieu of requiring advance deposits, or in order generally to provide funds for defraying administrative or advertising and sales promotion expenses until such time as sufficient moneys are collected for such purpose from the payment of the assessments which are established pursuant to this article, the director may receive and disburse for such expense purposes contributions which are made by producers, processors, distributors, or other handlers. Neither the advisory board nor the director is responsible for the repayment of such contributions. If, however, collections from the payment of established assessments credited to the respective marketing order accounts are sufficient to so warrant, the board shall recommend and the director shall authorize, the repayment of contributions, or authorize the application of such contributions to the assessment obligations of persons that made such contributions.
