(

a) Upon a finding by a two-thirds vote of the commission that this

chapter has not tended to effectuate its declared purposes, the commission may recommend to the secretary that this

chapter be suspended. However, any suspension shall not become effective until the expiration of the current marketing season. (

b) Alternatively, the secretary may be petitioned to suspend this chapter. The petition shall be signed by percent of the producers by number who produced not less than percent of the volume of winegrapes in the immediately preceding marketing season. The secretary shall hold a hearing on the petition after receiving it. (

c) The secretary shall, upon receipt of the recommendation to suspend this

chapter from the commission, or may, after holding the hearing on the petition to suspend this chapter, hold a referendum among producers to determine if the commission shall be suspended. However, the secretary shall not hold a referendum as a result of the petition unless the petitioner shows by the weight of evidence that this

chapter has not tended to effectuate its declared purposes. (

d) The secretary shall establish a referendum period, which shall not be less than days or more than days in duration. The secretary may prescribe additional procedures as may be necessary to conduct the referendum. At the close of the referendum period, the secretary shall tabulate the ballots filed during the period. If at least percent of the total number of producers from the lists established by the secretary participate in the referendum, the secretary shall suspend this

chapter if he or she finds either of the following has occurred:

(1) Sixty-five percent or more of the producers who voted in the referendum, voted in favor of suspension; and the producers so voting marketed a majority of the total quantity of winegrapes marketed in the preceding marketing season by all of the producers who participated in the referendum.

(2) A majority of the producers who voted in the referendum voted in favor of suspension; and the producers so voting marketed percent or more of the total quantity of winegrapes marketed in the preceding marketing season by all of the producers who voted in the referendum.
