A California appeals court on June 2 heard arguments in the first case that went to trial over allegations that Bayer AG’s glyphosate-based weed killer Roundup causes cancer, resulting in a $289 million judgment against the company.
The August 2018 jury verdict in favor of groundskeeper Dewayne Johnson, later reduced by a judge to $78 million, launched massive litigation over the weed killer that has led Bayer’s stock price to tumble more than 30 percent.
