In the event an excess tax has been voted as provided by Section 5-2001 and the order of the county board shall not have limited the time such excess will be required to be levied, the county board may thereafter levy such excess tax until such authority is revoked in manner hereinafter provided. However, no tax so voted for the payment of interest or principal or both of any bonds shall be discontinued by virtue of any of the provisions of this Division. The authority to levy such excess tax (except taxes to pay bonds) may be discontinued in the following manner: The County board may, by an order entered of record, and shall, by an order entered of record whenever five hundred legal voters of the County present petition to it asking that said excess tax be discontinued, provide for the submission of the question of discontinuing the additional tax at the next general election held in such county after the adoption of the resolution. The board shall certify the resolution and the question to the proper election officials, who shall submit the question at such election in accordance with the general election law. The proposition shall be in substantially the following form: "For discontinuing additional tax in excess of statutory limit of .... cents per $100 valuation" and "Against discontinuing additional tax in excess of statutory limit of .... cents per $100 valuation." The votes shall be canvassed and returned the same as those for county officers, and if a majority of the votes cast upon the question are for the discontinuing of the additional tax, then such additional tax shall not be levied thereafter.
