Mark has significant class action experience with clients who have served as named class representatives in diverse litigation related to Lysine, Vitamins, Laminates, Paxil, Ciprofloxacin, Pharmaceutical Industry AWP, Vytorin/Zetia, D-RAM, Projector Bulbs, Publication Paper and Health Insurance. The first civil class action case Mark ever worked on involved price-fixing with the product, lysine. Years later, a Hollywood movie (“The Informant!”) was made that dealt with the price-fixing of lysine and the criminal charges brought against some of the employees who worked for defendants, who wrongfully engaged in price-fixing. In another class action case where Mark’s client was a named class representative, the case made it all the way to the Second Circuit where, then Appellate Judge Sonia Sotomayor, wrote a favorable decision resulting in Mark’s client prevailing at the Second Circuit. However, that case was consolidated with another case, and was appealed to the United States Supreme Court, where Judge Sonia Sotomayer’s decision was overturned.
