FAC § 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.
