$25.27 millionVerdict

Edwin Hardeman, 70, sprayed Roundup on his Sonoma County property for about 26 years and was diagnosed with non-Hodgkin lymphoma in 2015. In the first federal Roundup bellwether trial, a unanimous San Francisco jury found in March 2019 that the herbicide was a substantial factor in his cancer and that Monsanto failed to warn, awarding $5,267,634 in compensatory damages and $75 million in punitive damages. Judge Vince Chhabria cut the punitive award to $20 million as constitutionally excessive, leaving a $25,267,634 judgment. The Ninth Circuit affirmed in May 2021 and the U.S. Supreme Court denied Monsanto's petition in June 2022.
