(In third paragraph, corrects to Alameda County Superior Court in Oakland, not San Francisco Superior Court)

May 13 (Reuters) - A California jury on Monday awarded more than $2 billion to a couple who claimed Bayer AG’s glyphosate-based Roundup weed killer caused their cancer, in the largest U.S. jury verdict to date against the company in litigation over the chemical.
The large punitive damages award is likely to be reduced due to U.S. Supreme Court rulings that limit the ratio of punitive to compensatory damages to 9:1. The jury awarded a total of $2 billion in punitive damages and $55 million in compensatory damages.
It was the third consecutive U.S. jury verdict against the company in litigation over the chemical, which Bayer acquired as part of its $63 billion purchase of Monsanto last year. Both other jury verdicts also came in California, one in state court and one in federal court.
The jury in Alameda County Superior Court in Oakland on Monday said the company was liable for plaintiffs Alva and Alberta Pilliod’s contracting non-Hodgkin’s lymphoma, a spokeswoman for the couple said.
It awarded $18 million in compensatory and $1 billion in punitive damages to Alva Pilliod, and $37 million in compensatory and $1 billion in punitive damages to his wife, Alberta Pilliod. The jury found Roundup had been defectively designed, that the company failed to warn of the herbicide’s cancer risk and that the company acted negligently.
The German chemicals giant faces more than 13,400 U.S. lawsuits over the herbicide’s alleged cancer risk.
The next jury trial in the glyphosate litigation is scheduled for August in Missouri state court, the first time a jury outside of California will hear a Roundup case. The trial will take place in St. Louis County, where Monsanto’s former headquarters are located.
Bayer in a statement on Monday said it was disappointed with the verdict and will appeal. A spokesman called the jury’s decision “excessive and unjustifiable.”
The company said both Alva and Alberta Pilliod had long histories of illnesses known to be substantial risk factors for non-Hodgkin’s lymphoma.
“The contrast between today’s verdict and (U.S. Environmental Protection Agency’s) conclusion that there are ‘no risks to public health from the current registered uses of glyphosate’ could not be more stark,” Bayer said.
Bayer says that decades of studies by the company and independent scientists have shown glyphosate and Roundup to be safe for human use. Bayer also points to several regulators around the world that found that glyphosate was not carcinogenic to humans.
The prior two jury verdicts against Bayer in U.S. Roundup trials triggered steep declines in Bayer shares.
A San Francisco state court jury in August 2018 awarded $289 million to a California groundskeeper, finding Monsanto’s glyphosate-based weed killers caused his cancer. That award was later reduced to $78 million and is on appeal.
In March, a federal jury in San Francisco awarded $80 million to another California man after finding Roundup caused his cancer. The company also said it would appeal that decision.
Adam Zimmerman, a law professor at Loyola Law School in Los Angeles, on Monday said it was too early to speculate about a potential settlement of the litigation by Bayer.
“The legal questions on appeal in the previous two cases will ultimately inform how this litigation proceeds,” Zimmerman said. It also remains to be seen how juries in other part of the country react to the evidence in upcoming trials, he said.
Shareholders have rebuked the company’s top management over its handling of the Monsanto acquisition and the litigation it inherited, which has wiped around 30 billion euros ($33.68 billion) from Bayer’s market value since the first jury verdict.
The Pilliods, a California couple in their 70s, allege the regular use of Roundup on their property between 1975 and 2011 caused them to develop cancers of the lymph system.
They filed their lawsuit in 2017 after being diagnosed with cancer in 2011 and 2015, respectively. Both of them are currently in remission, but their trial had been expedited due to the risk of a relapse and potentially short life expectancy.
Plaintiffs in the litigation allege that Monsanto had known about the herbicide’s cancer risk for decades, but failed to warn consumers and instead attempted to influence scientists and regulators to receive favorable assessments of its products. Bayer denies those allegations.
Lawsuits are largely based on a 2015 conclusion by the World Health Organization’s cancer arm, which classified glyphosate as “probably carcinogenic to humans.”
A 2017 Reuters investigatihere found that the World Health Organization's International Agency for Research on Cancer had dismissed and edited out "non-carcinogenic" findings that were at odds with its final conclusion that the chemical probably causes cancer.
The U.S. EPA, the European Chemicals Agency and other regulators have found that glyphosate is not likely carcinogenic to humans. The EPA on May 1 reaffirmed its earlier findings, saying glyphosate did not pose a risk to public health.
But Superior Court Judge Winifred Smith, who oversaw the Pilliod trial, did not allow Bayer to tell the jury about the latest EPA assessment, saying that the agency’s affirmation was not based on new science, but was merely a “comment.” ($1 = 0.8909 euros) (Reporting by Tina Bellon in New York Editing by Leslie Adler)
