The plaintiff alleged that Topps’ use of “redemption cards” – which are unique cards in specific packs of Topps trading cards that provide a consumer with a chance for a high-value or special card – constituted an illegal lottery, and that the packaging for the trading cards was misleading by not adequately disclosing that no purchase was necessary to obtain a chance to win a special card.

The case was litigated for over six years in Connecticut Superior Court (Stamford-Norwalk Division), including a three-week jury selection process and a four-week jury trial. The verdict provided a recovery for a class of approximately 1,500 independent auto body shops whose labor rates for work performed on automobiles insured by The Hartford had been suppressed for years. Four years later, in 2013, the Court issued a permanent injunction against The Hartford and also awarded the class $20 million in punitive damages. The punitive damage award was the largest awarded by a judge in the history of CUTPA.
