(35 ILCS 200/4-5)
    Sec. 4-5. State compensation not to affect county compensation. Any additional compensation payable from State funds to any county officer under this Code shall not affect any other compensation provided by law to be paid to the county officer. No county board may reduce or otherwise impair the compensation payable to a county officer because the person receives additional compensation payable from State funds under this Code. However, a county board may include State funds payable under this Code as reimbursements of or contributions to county officer salaries in determining the compensation of a county officer. As used in this Section, "county officer" includes any local assessment officer whose compensation is determined in whole or in part by a county board.
