The Supreme Court on Monday heard oral arguments over an effort from agrochemical company Bayer to shut down thousands of lawsuits alleging the company failed to warn users of its popular weed killer Roundup that the product poses a cancer risk. It was unclear Monday which way the justices would fall, though several appeared receptive to the argument that Bayer can be sued for damages under state laws despite conclusions from federal regulators that the product is safe. Bayer has been defending against litigation over Roundup since its $63 billion purchase in 2018 of Monsanto, the company that introduced the herbicide. John Durnell alleged that he developed non-Hodgkin lymphoma because of his exposure to Roundup. …A jury in a Missouri state court awarded him $1.25 million in damages, and Bayer appealed. …The justices will decide whether thousands of lawsuits against Roundup’s maker, Monsanto, are allowed under federal law.
