The Commission shall appoint a State advisory council and may appoint local or industry advisory councils, composed in each case of equal numbers of employer representatives and employee representatives, who may fairly be regarded as representatives because of their vocation, employment or affiliations, and of such members representing the general public as the Commission may designate. Such councils shall aid the Commission in formulating policies and discussing problems relating to the administration of Chapters 27 through 41 of this Title and in assuring impartiality and freedom from political influence in the solution of such problems. Such advisory councils shall serve without compensation, but shall be reimbursed for any necessary expenses.
