Sec. 15. At any time prior to 30 days before the first day of the marketing period, if an agreement on the issues in dispute between the accredited association and the handler has not been reached, the handler may elect not to purchase, directly or indirectly, any quantity of the agricultural commodity produced in the bargaining unit during the marketing period. If an agreement on the issues in dispute between the accredited association and the handler has not been reached, the affected producers may elect, as represented by the association, not to sell, directly or indirectly, any quantity of the agricultural commodity to the handler during the marketing period. If either party makes an election, the other party is not under an obligation to continue bargaining with the party so electing during that marketing period.
