66581. (a) Except as provided in subdivision (b), nine members of the commission, of which at least eight are handler members, constitute a quorum at any meeting for the transaction of all business and the carrying out of the duties of the commission. However, pending the appointment of initial members-at-large and the public representative, eight handler members constitute the quorum. Members-at-large who are handlers may be deemed handler members, if necessary, to fulfill the requirements of a quorum. Unless otherwise provided by this chapter or fixed by the commission, the vote of a majority of the commission members present at the meeting and constituting a quorum shall constitute the act of the commission.(b) Ten members of the commission, of which at least nine are handler members, constitute a quorum during any period in which the commission is increased to 19 members pursuant to Section 66561. All other provisions of subdivision (a) otherwise apply to this subdivision.(Amended by Stats. 1988, Ch. 958, Sec. 6.)
