Bayer Accused of Paying Plaintiff to Appeal Roundup-based Lawsuit to 11th Circuit 6 hours ago Bayer allegedly paid John Carson, a plaintiff who alleged the herbicide Roundup caused his cancer, to appeal a lawsuit against its subsidiary, Monsanto, to the Eleventh Circuit, according to Thursday’s filing in the lawsuit by other plaintiffs with similar claims against Monsanto in separate lawsuits. Reportedly, Bayer hoped that this appeal of the court’s dismissal of some of Carson’s claims would set a precedent, which could help the agriculture giant in many of the other lawsuits filed against Monsanto and its Roundup herbicide, so it negotiated to enter this “pay to appeal scheme.”
