(

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 director that this

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

The petition must 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 and percent of the vintners by number who acquired not less than percent of the volume of winegrapes in the immediately preceding marketing season. The director shall hold a hearing on the petition after receiving it. (

chapter from the commission, or may, after holding the hearing on the petition to suspend this chapter, hold a referendum among the producers and vintners to determine if the commission shall be suspended.

chapter has not tended to effectuate its declared purposes. (
