Corporations and their lawyers are pushing the idea that consumers who were duped by misrepresentations into buying products or overpaying for products have suffered “no injury.” The new report (PDF), “The Fiction of the ‘No-Injury’ Class Action,” examines that claim, testing its validity as a matter of fact and law. The report finds that, in the cases highlighted in recent testimony by corporate counsel, the consumers experienced real injuries, and the same kinds of injuries that the law has traditionally allowed people to go to court to redress – not only in consumer cases, but also in other areas of the law.
