Johnson & Johnson’s refusal to warn consumers its baby powder might cause ovarian cancer, despite four decades of knowing about the risk, created a “perfect storm of highly reprehensible conduct” that warranted a $4.7 billion verdict in Missouri.

Eric Holland, partner at Holland Law Firm in St. Louis, noted in his opposition to a motion for new trial on damages that while rare, “all factors support a large punitive damage award.”
