Cal. Food & Agric. Code § 78482

Any vacancy in the membership of the council which occurs during the unexpired term shall be filled by the director for the unexpired term from the eligible nominees. No council member or alternate shall serve more than two consecutive three-year terms. Service as an alternate does not disqualify a person to then serve two additional terms as a member, and a member who was appointed for a one-year or a two-year term may serve two additional three-year terms.
