In the nationwide litigation over talcum powder, Johnson & Johnson turned to Thomas Weaver of St. Louis-based Armstrong Teasdale to overturn a $72 million verdict in Missouri.

The Missouri Court of Appeals for the Eastern District on Tuesday vacated and reversed the jury award, the first of four verdicts that have slammed Johnson & Johnson over claims that its ubiquitous baby powder caused women to get ovarian cancer. Johnson & Johnson brought in Weaver, group leader of his firm’s appellate practice and a former nominee to the Missouri Court of Appeals for the Eastern District, to handle the appeal.
