Plaintiffs lawyers who got a $417 million talcum powder verdict last year said the Los Angeles judge who vacated their award did an “about-face” on their experts, according to an appeal brief filed on Wednesday.

The brief, filed before California’s 2nd District Court of Appeal, said Los Angeles Superior Court Judge Maren Nelson allowed the plaintiffs’ expert testimony before and during trial but, after the Aug. 21 verdict, found there was insufficient evidence linking Johnson & Johnson’s baby powder to the plaintiff’s ovarian cancer. Plaintiffs lawyer want the appeals court to reinstate the verdict and reverse Nelson’s order granting Johnson & Johnson’s motions for judgment notwithstanding the verdict and a new trial.
