"As we understand it, appellants' theory of damages is that, no matter what individual factors may have been involved in a class member's decision to purchase Lights, all consumers of Lights were led by false advertising to believe that Lights were healthier than regular cigarettes when they were not, such that purchasers are entitled to reimbursement for all amounts spent on the misrepresented cigarettes. Here, as in Peterson, appellants allege that the impact of the manufacturer's conduct on consumers was designed by the manufacturer to be the same for all members of the class: instilling a belief about the nature of a product. Therefore, the causal nexus is a question common to all class members. Philip Morris argues that, if smoked in a particular manner, Lights may have delivered what was advertised, which makes the inquiry into the falseness of its claims an individual inquiry. But appellants counter that Philip Morris purposefully withheld this important information about smoking methods from all consumers and expended enormous sums in deceptive advertising (the prohibited conduct) to influence consumers to pay money (the damages claimed) for a misrepresented product. Group Health instructs that the required causal nexus may be established when there is something to connect "the claimed damages and the alleged prohibited conduct." 621 N.W.2d at 14. The district court appropriately relied on supreme court cases issued after its initial denial of class certification for the proposition that the proof of causation required in consumer-protection class actions is less stringent than proof of causation required in actions for common-law fraud and does not require proof of individual reliance, but merely a causal relationship between the advertiser's actions and the alleged injury. See Wiegand v. Walser Auto. Grps., Inc., 683 N.W.2d 807, 811-12 (Minn.2004) (stating that a showing of "individual consumer reliance" is not necessary to state a claim for damages under Minn.Stat. § 8.31, subd. 3a);"
