735 ILCS 5/20-103
Any person who by means of a false record, statement or representation, or by willful concealment of any material fact, or by other fraudulent scheme or device on behalf of himself, his dependents or others, knowingly obtains from the State or local governmental unit compensation, benefits or remuneration to which he is not entitled, or in a greater amount than that to which he is entitled, shall be liable for full repayment of such compensation, benefits or remuneration received to which the person was not entitled. In addition to any other penalties provided by law, the court shall impose civil penalties consisting of interest on the amount of the compensation, benefits or remuneration received to which the person was not entitled at the maximum legal rate for interest on judgments in effect on the date the payment was made to such person for the period beginning on the date upon which payment was made to the date upon which repayment is made; and may impose either of the following penalties: (1) an amount not to exceed 3 times the amount of such compensation, benefits or remuneration to which the person was not entitled; or (2) an amount not to exceed $2,000 for each instance that the person used any fraudulent scheme or device to obtain compensation, benefits or remuneration to which he is not entitled, whichever penalty the court deems more appropriate. Except as provided by Section 20-105, upon entry of a judgment for repayment of such compensation, benefits or remuneration, or for any civil penalties assessed by the court, a lien shall attach to all property and assets of such person until the judgment is satisfied, subject to the exemptions otherwise applying to the real and personal property of judgement debtors.
