Bayer Appeal to Dismiss Roundup Weedkiller Lawsuits Rejected by U.S. Supreme Court

The U.S. Supreme Court has rejected an appeal by German company Bayer AG to dismiss legal claims by customers who assert one of its products — glyphosate-based Roundup weedkiller — causes cancer. The multinational chemical and pharmaceutical company could potentially owe billions of dollars in damages, reported Reuters.

The decision by the Supreme Court meant a verdict by a lower court that had upheld $25 million awarded to Edwin Hardeman — a California resident and Roundup consumer who blamed Bayer’s weedkiller for his cancer after using it at his home for 26 years — was left intact.

In 2015, Hardeman was diagnosed with non-Hodgkin’s lymphoma and contended that Bayer hadn’t given a warning as to the cancer risks of glyphosate, The Washington Post reported.

“[N]ow thousands of other cancer victims can continue to hold Monsanto accountable for its decades of corporate malfeasance,” lawyers representing Hardeman, Jennifer Moore and Aimee Wagstaff said in a statement, as reported by The Washington Post.

Bayer acquired Monsanto, the original maker of Roundup, in 2018.

The International Agency for Research on Cancer (IARC) classified the herbicide glyphosate as “probably carcinogenic to humans” in 2015.

The weedkiller is still approved for use in the U.S., Europe and other places, reported BBC News. Parts of the European Union have banned the herbicide, according to Deutsche Welle.

A 2019 analysis showed that glyphosate was the most used pesticide in the U.S., the Midwest Center for Investigative Reporting said.

Bayer is currently in the midst of thousands of lawsuits, with another Bayer appeal on the horizon for the Supreme Court in the weeks to come, Reuters reported. The Court’s rejection of the current appeal by Bayer led to a 2.9 percent dip in the company’s shares.

Last week, the U.S. Environmental Protection Agency (EPA) was ordered by a federal appeals court to reexamine if glyphosate presents risks that are unreasonable to people and the environment.

In a decision favorable to farm worker, environmental and food safety advocates, the U.S. Court of Appeals for the Ninth Circuit ruled that the EPA hadn’t sufficiently considered if glyphosate poses a threat to endangered species and causes cancer.

In its annual report released in March, Bayer said that about 107,000 of its approximately 138,000 cases had been resolved. The cases against the company argue that customers should have been warned of the alleged risk of cancer.

Bayer has asserted that the claims that glyphosate and Roundup cause cancer are contrary to science and the approval of the EPA, which has supported assertions that glyphosate is non-carcinogenic and, when used as the label advises, not a public health risk.

Bayer has asked for a review of the Supreme Court’s decision in the Hardeman case. The company argued that it should not be punished when the EPA wouldn’t allow a cancer warning to be put on its product and had determined it to be safe.

Bayer said it plans to replace glyphosate-based weed-killing ingredients in products for non-professionals in the U.S. with alternative active ingredients in order to “manage litigation risk in the U.S.,” but not due to concerns about safety, reported The Washington Post.
