The Fifth Circuit Court of Appeals has thrown out a $502 million verdict against Johnson & Johnson and subsidiary DePuy Orthopaedics over defective hip-implant claims, ruling the trial judge committed “serious evidentiary errors” and allowed “misrepresentations” by the plaintiffs lawyer to go before the jury.

The panel also threw out two “aiding and abetting” claims against Johnson & Johnson, but it allowed two others remain for negligent undertaking and nonmanufacturer seller.
