Litigation Overview

Litigation Overview

Farmers and growers have been using glyphosate-based herbicides safely and effectively to control weeds for more than 40 years. These products continue to play a critical role in helping farmers manage weeds and sustainably deliver crops to markets around the world.

The litigation over glyphosate primarily stems from one place: an opinion by a group called IARC. IARC is not a regulatory authority and did not conduct any original scientific studies. Yet in 2015, after IARC classified glyphosate as a “probable carcinogen,” trial attorneys in the U.S. began running advertisements to recruit plaintiffs for lawsuits against Monsanto, the manufacturer of many glyphosate-based herbicides (i.e., RoundupTM-branded herbicides). These lawsuits rely heavily on IARC’s classification, which has many significant limitations and flaws and runs counter to an extensive body of science supporting glyphosate’s safe use. More than four years after reaching its opinion, leading pesticide regulators around the world continue to conclude that glyphosate is not carcinogenic and that glyphosate-based herbicides are safe when used as directed.

On November 9, 2022, a defense verdict was issued in the Ferro trial in St. Louis County, Missouri, the sixth consecutive win for Monsanto in this litigation. The next trial is Constantine in Barnstable County, Massachusetts, which is scheduled to begin on January 4, 2023. 

Bayer will vigorously defend its products based on the strong body of science that confirms glyphosate and glyphosate-based products are safe when used as directed and that glyphosate does not cause cancer.

The trial schedule continues to remain fluid and subject to change based on multiple factors, including the COVID pandemic, the schedules of courts and parties, and the continued efforts by parties to resolve cases.

    Key Dates

The company argued in its briefs that the “verdicts do not reflect the evidence presented in the case; they reflect deep passion and prejudice borne from plaintiffs’ counsel’s improper argument rested on inflammatory, fabricated and irrelevant evidence that should have been excluded…  The resulting trial focused not on ascertaining the truth regarding the state of the science, causation, and compliance with legal duties, but instead on vilifying Monsanto in the abstract.” Read Monsanto’s Motion for Judgment Notwithstanding the Verdict here, Motion for New Trial here, and Bayer’s statement here.

    Monsanto filed to appeal the Johnson verdict in the Court of Appeal of the State of California and believes that the liability verdict and damage awards are not supported by the evidence at trial or the law. On March 19, 2021, Bayer announced that it had decided not to file a petition for certiorari with the U.S. Supreme Court, which will bring an end to the case. The decision was not based on the merits of this case but reflects strategic considerations that the Hardeman case, currently pending in the United States Court of Appeals for the Ninth Circuit, will serve as a better case for review by the Supreme Court.

    Key Dates

    • On August 10, 2018, a jury in Dewayne Johnson v. Monsanto, a case in California state court, found Monsanto liable for Mr. Dewayne Johnson’s non-Hodgkin’s lymphoma (NHL). Judge Suzanne R. Bolanos, who oversaw the trial, later reduced the punitive damage award by $211 million, from $289 million to $78 million.
    • On April 24, 2019, Monsanto filed to appeal the Johnson verdict in the Court of Appeal of the State of California. Monsanto’s brief argued that the evidence at trial fell far short of the substantial evidence required to support any theory of liability in the case and to prove causation in light of the favorable international consensus among health regulators that glyphosate is not carcinogenic and the extensive body of science on which their assessments rest. The Company argued the liability claims are preempted by federal law as well. Moreover, the brief argued that the Court’s exclusion of EPA and international regulatory evidence, particularly in light of its admission of IARC’s opinion, was reversible error that requires a new trial.
