No expenditure during any fiscal year or biennial period shall be made in excess of the amounts indicated in the adopted budget statement, except as authorized in section 13-511, or by state law. Any officer or officers of any governing body who obligates funds contrary to the provisions of this section shall be guilty of a Class V misdemeanor.
