Plaintiffs lawyers who lost a California appeals court decision affirming dismissal of a $417 million talcum powder verdict have petitioned the California Supreme Court to review the case.

In a brief filed Aug. 9, attorney Mark Robinson sought to reverse last month’s decision by the Second District Court of Appeal, which lawyers in the multidistrict litigation in New Jersey over Johnson & Johnson’s baby powder cited in briefings ahead of a hearing on expert evidence. Monsanto Co. also unsuccessfully relied upon the ruling in motions hoping to overturn a $2 billion Roundup verdict.
