Pfizer v. Sup. Ct., B188106

In plaintiffs' action against Pfizer, the manufacturer of Listerine mouthwash, pursuant to the Unfair Competition Law (UCL) and False Advertising Law, claiming that Pfizer marketed the mouthwash in a misleading manner by representing that the use of it can replace the use of dental floss in reducing plaque and gingivitis, defendant's petition for writ of mandate seeking to overturn superior court's order certifying the class action is granted as the ruling certifying a class consisting of all persons who purchased Listerine in California during a six-month period is overbroad, and In re Tobacco II Cases, 46 Cal.4th 298 (2009), does not require a different disposition in this case.
