(735 ILCS 5/2-2105)
    (This Section was added by P.A. 89-7, which has been held unconstitutional)
    Sec. 2-2105. Changes in design or warning; inadmissibility. When measures are taken which, if taken previously, would have made an event less likely to occur, evidence of the subsequent measures is not admissible to prove a defect in a product, negligence, or culpable conduct in connection with the event. In a product liability action brought under any theory or doctrine, if the feasibility of a design change or change in warnings is not controverted, then a subsequent design change or change in warnings shall not be admissible into evidence. This rule does not require the exclusion of evidence of subsequent measures when offered for another purpose such as proving ownership, control, or impeachment.
