The Ninth Circuit has confirmed in quadrophonic sound that plaintiffs cannot avoid preemption by relying on vague and speculative allegations to establish a parallel claim. The court affirmed the dismissal of four lawsuits by plaintiffs claiming they were injured by breast implants on the grounds that their claims are barred by the 1976 Medical Device Amendment to the Food, Drug and Cosmetic Act (MDA). Sewell v. Mentor Worldwide, LLC, et al., no. 19-56393; Vieira v. Mentor Worldwide, LLC, et al., no. 19-56394; Billetts v. Mentor Worldwide, LLC, et al., no. 19-56398; Nunn v. Mentor Worldwide, LLC, et al., no. 19-56391.
In each case, California plaintiffs alleged their breast implants were defective and caused them to experience fatigue, muscle pain, and migraines. The district courts dismissed the complaints for failure to state a claim on grounds of preemption, and plaintiffs appealed.
