(2) Except as provided in ORS 328.445 (2), warrants in payment of school district obligations shall be issued only when there are insufficient funds to pay the warrant and shall be indorsed "not paid for want of funds". Warrants may be issued at the end of each school month, if necessary. School warrants shall not be issued without a vote of the district school board. They must be signed by the chairperson of the board and countersigned by the district clerk. If the chairperson is absent or unable to execute the warrants, the board may authorize any member of the board to act as chairperson in executing the warrants.
(3) Unless the district school board has designated a lower rate of interest, which rate must appear on the face of the warrants, warrants indorsed "not paid for want of funds" shall draw the legal rate of interest from date of indorsement until paid.
(4) Funds becoming available for payment of warrants indorsed "not paid for want of funds" shall be applied in payment in the order in which the warrants were so indorsed. [Amended by 1965 c.100 §68]
