Mississippi Code Title 21. Municipalities § 21-39-17

All expenditures of money from the treasury of any municipality for any purpose whatsoever shall be in pursuance of the allowance of a claim as hereinbefore specified in Section 21-39-9, or in pursuance of a specific appropriation made by order, which such appropriation shall be specific as to each separate expenditure in so far as may be practical. If the mayor, clerk, or any other person shall wilfully or feloniously issue, sign or attest any warrant for the expenditure of money from the municipal treasury when such expenditure is not authorized by an order entered on the minutes of such municipality, then such person shall be guilty of a misdemeanor and, upon conviction, shall be punished by a fine of not more than five hundred dollars, or by imprisonment in the county jail for not more than six months, or by both such fine and imprisonment, in the discretion of the court. In addition such person shall, upon conviction, automatically be removed from his office.
