Illinois Code § 1

§ 1.

Any person holding office under the Constitution of the State of Illinois and every elected official of local government or of any school district who is convicted in any court of the State of Illinois or of the United States of a felony, bribery, perjury, or other infamous crime, as understood in Section 1 of Article XIII of the Constitution of 1970, shall be, upon conviction, ineligible to continue in such office. If, subsequently, a final order reverses the conviction, eligibility to hold the office, to the extent of the original term then remaining, is restored, and the officer shall be reinstated, for the duration of the term of office remaining. Each such officer shall be promptly repaid all compensation withheld from him as a result of his removal. No rights of an officer under any pension plan subject to the jurisdiction of this State, of which the officer is a member at the time of his ineligibility for office, shall be abridged if the officer is returned to office by this Act. After conviction and until a final order of reversal, there shall be no payment of compensation to any such officer. Upon the conviction and ineligibility of any person under this Act, a successor shall be chosen according to law. This successor shall hold office for the remainder of the term or until a final order reversing the conviction is entered. (Source: P.A. 88-419.)
