NEW YORK—A federal appeals court on Tuesday revived a lawsuit by a Georgia man claiming Bayer AG’s Roundup weedkiller caused his cancer, the latest in a string of legal defeats for the company as it seeks to avoid potentially billions of dollars in damages.
The 11th U.S. Circuit Court of Appeals in Montgomery, Alabama, rejected Bayer’s argument that federal law shielded it from state law claims like the one brought by John Carson, who said he was diagnosed with a type of cancer called malignant fibrous histiocytoma in 2016 after using Roundup for 30 years. Carson said the company should have warned of cancer risk on the product’s label.
