Notable Matters

  • Served as trial counsel in Clark v. Monsanto, a trial involving claims that the herbicide Roundup causes Non-Hodgkin Lymphoma. Cali handled several witnesses including the direct examination of Monsanto’s weed science expert and cross-examination of the plaintiffs’ sole expert on human studies. Clark was the fourth case in this mass tort to go to trial, with the three previous trials resulting in verdicts against Monsanto ranging from $81 million to over $2 billion. After a single day of deliberation, a jury delivered the first-ever verdict for Monsanto in the Roundup mass tort litigation.
  • Member of trial team for Monsanto in Hardeman v. Monsanto, the first federal-court trial over allegations that Roundup causes Non-Hodgkin’s Lymphoma. The jury returned a verdict for the plaintiff. Cali has assisted with post-trial briefing as well as the ongoing expert witness preparation and strategy in the larger MDL.
  • Helped brief summary judgment for Georgia-Pacific in Kleen Products LLC et al. v. Packaging Corporation of America et al., a multi-billion-dollar class action in Chicago federal court alleging Sherman Act violations by the largest manufacturers in the containerboard and corrugated products industries. The court granted summary judgment for Georgia-Pacific one day after it preliminarily approved a settlement in which the company’s codefendants agreed to pay over $350 million.
  • Member of trial team for the NCAA in lawsuits brought by current and former student- athletes challenging, under the Sherman Act, NCAA rules limiting the level of athletics-based financial aid and benefits that student-athletes may receive. The Court’s opinion reaffirmed the procompetitive value of the NCAA’s rules limiting pay for student-athletes while enjoining certain limitations on benefits that student-athletes may receive.
  • Member of trial teams for Bayer in the first two federal multi-district litigation bellwether trials in Louisiana involving the blood-thinner Xarelto, and in the second state-court bellwether trial in the Philadelphia Court of Common Pleas. Obtained complete defense verdicts in all three trials.
  • Member of trial team on behalf of Facebook, Oculus VR, and individual defendants in ZeniMax Media et al. v. Oculus VR et al., a federal jury trial in the Northern District of Texas. Plaintiffs sought $6 billion in damages based on allegations that the defendants improperly used its trade secrets and other intellectual property in designing the Oculus Rift virtual reality headset. Obtained a defense verdict for Facebook and a partial defense verdict for the remaining defendants, including the jury’s rejection of plaintiffs’ lead claim of trade secret misappropriation. Wilkinson Stekloff’s post-trial briefing persuaded the court to sanction plaintiffs withholding evidence and prevented them from recovering $40 million in attorneys’ fees.
