Thomas Persson and Jon Nokes founded Smart Inventions, Inc., to market household consumer products. The success of their first product, the Smart Mop, continued with later products, which were sold through infomercials. Persson and Nokes were the firm’s officers and equal shareholders, with Persson responsible for product development and Nokes in charge of day-to-day activities. By 1998, they had become dissatisfied with each other’s efforts. Nokes represented the firm as financially “dying,” “in a grim state...worse than ever,” and offered to buy all of Persson’s shares for $1.6 million. Persson accepted. On the day that they signed the agreement to transfer the shares, Smart Inventions began marketing a new product—the Tap Light. It was an instant success, generating millions of dollars in revenues. In negotiating with Persson, Nokes had intentionally kept the Tap Light a secret. Persson sued Smart Inventions, asserting fraud and other claims. Under what principle might Smart Inventions be liable for Nokes’s fraud? Is Smart Inventions liable in this case? Explain.
