The action of the commission in making nominations with respect to any vacancy shall be taken only at a meeting, and the voting on persons under consideration shall be by secret ballot. When a decision as to the three nominees has been reached, it shall be evidenced by the execution of a certificate of nomination (which may be in the form of a communication to the governor), setting forth the nominations made and the number of commissioners supporting each person nominated, signed on behalf of the commission by the chair and the secretary. The commission or its chair shall forthwith transmit such certificate to the governor.
