Section 65 ILCS 5/5-3-9 - Officers; oath or affirmation; bond(a) Before entering upon the duties of their respective offices, all officers, whether elected or appointed, shall take and subscribe the oath or affirmation required by the Illinois Constitution. The subscribed oath or affirmation shall be filed in the office of the city or village clerk.
(b) Before entering upon the duties of their respective offices, all officers, except those specified in Section 5-3-8, shall execute a bond with security to be approved by the corporate authorities. The bond shall be payable to the city or village in the penal sum directed by resolution or ordinance, conditioned upon the faithful performance of the duties of the office and the payment of all money received by the officer, according to law and the ordinances of that city or village. The bond may provide that the obligation of the sureties shall not extend to any loss sustained by the insolvency, failure, or closing of any bank or savings and loan association organized and operating under the laws of either the State of Illinois or the United States in which the officer has placed funds in the officer's custody if the bank or savings and loan association has been approved by the corporate authorities as a depository for these funds. The treasurer's bond shall be in an amount of dollars that is not less than the greater of $50,000 or 3 times the latest Federal census population or any subsequent census figure used for Motor Fuel Tax purposes. These bonds shall be filed with the city or village clerk, except that the bond of the clerk shall be filed with the city or village treasurer.(c) Subject to the limitations of subsection (b), the city council or village board may fix the amount and penalty of the bonds of all officers and of all employees charged with the custody of money or property. It may also require the giving of additional bonds, increase or decrease the amount and penalty of the bonds of any officer, and require the giving of a new bond where the security of an original bond has become either insufficient or in any way impaired, upon penalty of removal from office. The power vested in the city council or village board by this Section shall be so administered as to protect the interests of the city or village from danger of financial loss and shall never be used as a means of removing any person from the service of the city or village without a hearing before the civil service commission, if there is one, in accordance with law. In that case, the city employee or official whose office is sought to be declared vacant by reason of a failure to give a new, additional, or increased bond shall have the right to have a hearing before the civil service commission upon the question involved.
