[35 ILCS 735/3-2]  See 86 Ill. Adm. Code 700, Uniform Penalty and Interest Act. b)         No interest will be allowed if the overpayment is found by the Department to have been made deliberately for the purpose of drawing interest, or if the overpayment is ascertained not to have been bona fide for some other reason. c)         When a claim that is allowed is paid by means of a credit memorandum instead of by means of a cash refund, the claim will be considered to have been paid when the credit memorandum is issued by the Department to the claimant, and no interest will be allowed or paid by the Department for any period subsequent to that, even if the claimant does not use or assign the credit memorandum immediately after it is issued.
