(d) Copies of all audits made by the Department of the Auditor General shall be promptly submitted to the board and to the Governor.

(e) Unless the Department of the Auditor General shall neglect or refuse to make annual, quarterly or special Audits, as hereinabove required, it shall be unlawful for the board to expend any money appropriated to it by the General Assembly for any audit of its affairs, except for the payment of the compensation and expenses of such auditors as are regularly employed as part of the administrative staff of the board.
