Tips for Building a Successful Defense Against Exceptions to Illinois’ Moorman Doctrine

The Moorman Doctrine bars recovery in tort for purely economic losses—such as repair costs or lost profits—when a defective product causes no personal injury or damage to other property. Established in Moorman Manufacturing Co. v. National Tank Co. (1982), the rule holds that such losses are properly addressed through contract remedies, not tort. Limited exceptions apply for sudden and dangerous occurrences, intentional misrepresentation, and certain negligent misrepresentations by information suppliers.
