Economic Loss Doctrine: Illinois vs. Pennsylvania

In Illinois, the Economic Loss Doctrine is primarily utilized to delineate the boundaries between tort and contract law. The Illinois courts have held that recovery for solely economic damages must be sought under contract law, not tort law. This approach was articulated in the landmark case of 'Moorman Manufacturing Co. v. National Tank Co.', which established that tort claims cannot be asserted for purely economic losses resulting from the breach of a contractual duty. The doctrine is applied to restrict recovery when a plaintiff seeks damages that arise out of disappointed economic expectations, such as lost profits or property damage that does not also involve physical injury.

In Pennsylvania, the Economic Loss Doctrine similarly restricts tort claims for purely economic damages but does so with slightly different nuances. Pennsylvania courts recognize the doctrine primarily to prevent tort claims when the underlying claim arises from a contractual relationship. The leading case, 'County of Northampton v. H. S. & W. Co.', emphasizes that economic losses associated with a project's defect must be addressed through contract law rather than tort law. Pennsylvania’s application suggests that if the parties are in a contractual relationship and the losses are purely economic, recovery must arise from contract principles, thus upholding the integrity of contract law.
