Hardeman Trial (2019)

Hardeman v. Monsanto Co.

Wisner Baum (formerly Baum Hedlund) Assists with Bellwether Case on Monsanto’s Roundup

Edwin Hardeman v. Monsanto Co. was the first federal Roundup cancer lawsuit to proceed to trial before U.S. District Judge Vince Chhabria. The trial was a bellwether case for more than 1,600 other plaintiffs with lawsuits consolidated in San Francisco’s Federal Court, all alleging that exposure to Monsanto’s Roundup herbicide and its active ingredient, glyphosate, cause non-Hodgkin lymphoma (NHL). This was the second Roundup cancer case to go to trial against Monsanto.

After weeks of trial proceedings, a jury awarded Edwin Hardeman $80 million in damages. The judge overseeing the case later reduced the verdict to $25.2 million.

6/21/2022 update: The Supreme Court denied Bayer’s petition for a writ of certiorari, allowing Mr. Hardeman’s final judgment of $25.2 million to remain intact.

Statement from attorney R. Brent Wisner, who served on the trial team in Hardeman v. Monsanto Co.:

“The decision is not surprising, but it is welcomed. Monsanto will never get the ‘magic’ preemption bullet it hoped for. This litigation will continue to be fought in the trial courts, in front of juries, like it should be. I, for one, am looking forward to trying a case this Fall in California, having not been in the litigation since the Pilliod trial. I know Monsanto has had some recent trial victories. I'm hoping to change that, especially now that the appellate courts are, for all practical purposes, out of the way.”

5/9/2022 update: The Justice Department filed an Amicus Brief stating that Bayer’s writ of certiorari should be denied.

8/16/2021 update: Bayer submitted a petition for a writ of certiorari with the United States Supreme Court. Several amicus briefs have since been filed. The petition is pending.

5/14/2021 update: Ninth Circuit Court of Appeals in San Francisco denied Bayer’s appeal in Hardeman v. Monsanto Co.

Statement from co-lead counsel (Moore Law Group and Andrus Wagstaff) representing Mr. Hardeman:

“Mr. Hardeman is very pleased that the Ninth Circuit affirmed the jury’s verdict. The Court ruled that ‘substantial evidence of Monsanto’s malice was presented to the jury, supporting punitive damages.” Internal emails showed that Monsanto knew of the risk of cancer and failed to warn consumers like Mr. Hardeman. Today is significant for consumers holding pesticide companies like Monsanto accountable for causing thousands of people cancer.”

3/23/2020 update: Public Citizen and the Center for Food Safety filed amicus briefs in support of plaintiff-appellee Edwin Hardeman.

12/13/2019 update: Monsanto filed an appeal of the Hardeman verdict in the U.S. Court of Appeals Ninth Circuit.

7/17/2019 update: Amended Judgment. The judge reduced Mr. Hardeman’s verdict to $25.2M.

7/15/2019 update: Order Granting in Part and Denying in Part Monsanto’s Motion for Judgment on Punitive Damages, Denying Monsanto’s Motion for New Trial on Compensatory Damages

Edwin Hardeman, 70, and his wife spent decades living in Sonoma County, California, on 56 acres of land previously used as an exotic animal refuge. He started using Monsanto herbicides to treat poison oak, overgrowth, and weeds on his property in 1986 and continued using Roundup through 2012. Mr. Hardeman was diagnosed with B-cell NHL in February of 2015, about a month before the International Agency for Research on Cancer (IARC) classified glyphosate, a key ingredient in Roundup, as a “probable human carcinogen.”

Roughly a year after his diagnosis, Mr. Hardeman retained the law firm of Andrus Wagstaff and filed a lawsuit against Monsanto Co. on Feb. 12, 2016. Judge Chhabria selected his case as the first out of hundreds of other Monsanto Roundup cancer cases in the MDL to go before a jury.

In January of 2019, Judge Chhabria decided to grant Monsanto’s request to bifurcate Mr. Hardeman’s trial. Bifurcation creates two phases for trial.

The first phase addresses evidence relevant to causation, specifically, whether or not Monsanto’s Roundup herbicide significantly contributed to Mr. Hardeman developing NHL. If the jury finds that exposure to Roundup significantly contributed to Mr. Hardeman’s cancer, the case proceeds to the second phase, which focuses on Monsanto’s knowledge, conduct and damages (both compensatory and punitive).

Aimee Wagstaff (lead trial counsel) of Andrus Wagstaff and Jennifer Moore of Moore Law Group represent Mr. Hardeman. R. Brent Wisner of Wisner Baum will conduct direct examination of Dr. Christopher Portier, one of the plaintiff’s expert witnesses. Mr. Wisner served as co-lead trial counsel in Johnson v. Monsanto.

She is the author of numerous toxicology publications, lectures and presentations. Dr. Ritz engaged in a systematic review of the literature in this case, utilized the Bradford Hill Criteria and concluded that “to a reasonable degree of scientific certainty, glyphosate causes NHL. Furthermore, to a reasonable degree of scientific certainty, glyphosate-based formulations, including Roundup, cause NHL.”

She received her MD and a PhD in Medical Sociology from the University of Hamburg Germany in 1983 and 1987 and received doctoral training and a PhD degree in Epidemiology in 1995 from UCLA.

  • Director of the National Center for Environmental Health, Center for Disease and Prevention.
  • Director of the Agency for Toxic Substances and Disease Registry (ATSDR).

Dr. Portier conducted a systematic review of the literature in this case, utilized the Bradford Hill Criteria, and concluded, “[i]n my opinion, glyphosate probably causes NHL and, given the human, animal and experimental evidence, I assert that, to a reasonable degree of scientific certainty, the probability that glyphosate causes NHL is high.”
