Every board or officer authorized by law to issue requisitions upon the Auditor for payment of money out of the State Treasury, shall, before any such money is paid out of the State Treasury, certify to the Auditor that the money for which such requisition is made is needed for present use for the purposes for which it was appropriated; and the Auditor shall not issue his warrant to pay any money out of the State Treasury unless he is satisfied that the same is needed for present use for such purposes.
