Paraquat litigation grows, first trial set for May 10

Six more lawsuits alleging Syngenta’s weed killing pesticide paraquat causes Parkinson’s Disease were filed last week in Pennsylvania, California and Illinois, adding to more than a dozen similar lawsuits already filed in U.S. courts.

The lawsuits all allege that exposure to paraquat,  which is banned in more than 30 countries though not in the United States, causes the incurable and progressive Parkinson’s disorder that affects nerve cells in the brain, leading in advanced cases to severe physical debilitation and often dementia and death.

Many Parkinson’s experts say the disease can be caused by a range of factors, including exposure to pesticides such as paraquat, as well as other chemicals.

The first trial set to take place in the United States is to begin on May 10 in St. Clair County Circuit Court in Illinois. Missouri lawyer Steve Tillery  is representing the plaintiffs in Hoffman V. Syngenta and said he plans to introduce evidence that includes internal company records showing Syngenta has known for decades that its product causes Parkinson’s Disease.

The defendants in the Hoffman case, as well as the other cases filed, name the Swiss-based Syngenta and Chevron USA as defendants.

Both Chevron and Syngenta deny there is a connection between the disease and the weed killer.

Chevron distributed and sold paraquat products in the United States starting with an agreement with a Syngenta predecessor called Imperial Chemical Industries (ICI), which introduced a paraquat-based herbicide called Gramoxone in 1962. Under a license agreement, Chevron had the right to manufacture, use, and sell paraquat formulations in the U.S.

Syngenta says that its paraquat products have been approved as “safe and effective” for more than 50 years and it will “vigorously” defend the lawsuits. Syngenta is owned by China National Chemical Corporation, known as ChemChina.

The complaints were filed on April 30 by a team of law firms: DiCello Levitt Gutzler, Saltz Mongeluzzi & Bendesky, P.C. and  Searcy Denney.

Mark DiCello, one of the plaintiffs’ attorneys bringing the cases, said Chevron and Syngenta have “long known they were peddling this poison,” and that the science surrounding paraquat “is conclusively on the side of the plaintiffs.”

Jeffrey Goodman, another of the plaintiffs’ attorneys helping bring the litigation said the filings so far are but the “tip of the iceberg” of what he expects to expand into a major mass tort case.

“The manufacturers of paraquat knew for decades that their product was linked to Parkinson’s disease yet chose to hide this information from regulators and the public,” Goodman said.

The newly filed cases are:

The new cases join at least 14 lawsuits filed by eight different law firms in six different federal courts across the country.

Federal court rejects Syngenta’s bid to toss lawsuit over paraquat herbicide

A federal judge has denied Swiss chemical company Syngenta’s effort to throw out one of a growing number of lawsuits alleging the company’s weed killing products cause Parkinson’s Disease. The decision offers a boost for the expanding number of law firms and plaintiffs making similar claims.

In an April 12 ruling, U.S. District Judge John Ross in the Eastern District of Missouri denied a motion filed by Syngenta and co-defendant Chevron that sought to dismiss a lawsuit brought by married Missouri couple Henry and Tara Holyfield.

“We were pleased that the court denied the motions to dismiss,” said Steven Crick, an attorney with the firm of Humphrey, Farrington & McClain who is representing the Holyfields. “We are also confident that the defendants’ efforts to dismiss or derail the case will continue.”

The lawsuit alleges Henry Holyfield developed Parkinson’s, a debilitating and incurable progressive nervous system disorder, due to his exposure to paraquat in his work as a crop duster. The suit alleges that paraquat was distributed “without adequate instructions on safe use” and “without instructions or warnings that the paraquat was dangerous to health and life and caused disease.”

Syngenta manufacturers and distributes paraquat-based Gramoxone, a widely used weed killer popular with American farmers but banned in more than 30 countries because it is known to be acutely toxic. Syngenta acknowledges the dangers of accidental poisoning associated with paraquat, and its products carry strict warning labels about precautions needed for safe use.

But the company has denied the validity of scientific research that has found associations between paraquat exposure and Parkinson’s Disease.

Chevron gained sales and distribution rights for Gramoxone paraquat product in the United States in an agreement with a Syngenta predecessor called Imperial Chemical Industries (ICI), which introduced paraquat-based Gramoxone in 1962. Under a license agreement, Chevron was granted rights to manufacture, use, and sell paraquat formulations in the U.S.

In their motion to dismiss the case, Syngenta and Chevron argued that the Holyfield claims were preempted by federal law governing regulation of paraquat by the Environmental Protection Agency (EPA).

“Paraquat has been heavily regulated by the EPA for decades under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA)…” the motion states. “Through decades of scrutiny, the EPA’s judgment continues to be that paraquat is safe for sale and use so long as EPA-prescribed precautions are taken and instructions are followed. To ensure uniformity, FIFRA prohibits states from imposing any labeling requirements “in addition to or different from” FIFRA’s requirements and EPA-approved labels… But that is exactly what the complaint seeks to do.”

Judge Ross said the argument was flawed. FIFRA states that registration approval by the EPA “does not
constitute an absolute defense” to claims that a product was “mislabeled,” he wrote in his decision. Moreover, a 2005 U.S. Supreme Court ruling in a case titled Bates v. Dow Agrosciences established that the EPA’s approval of a product does not rule out claims of a failure to warn brought under state law.

“This Court is aware of no case since Bates in which a court has declined jurisdiction over a FIFRA-related claim pursuant to the doctrine of primary jurisdiction,” the judge wrote in his ruling. “The results of the EPA’s review of paraquat, moreover, will not dictate the success or failure of Plaintiffs’ claims.”

There are currently at least 14 lawsuits filed by eight different law firms in six different federal courts across the country. The lawsuits are all filed on behalf of plaintiffs who have been diagnosed with the neurodegenerative disorder, and they all allege exposure to Syngenta’s paraquat caused their conditions. Several other cases making the same allegations are pending in state courts as well.

Move to consolidate U.S. paraquat litigation as cases mount against Syngenta

Lawyers suing Swiss chemical company Syngenta are asking a U.S. judicial panel to consolidate more than a dozen similar lawsuits under the oversight of a federal judge in California. The move is a telling sign of the expansion of litigation that alleges the company’s weed killing products cause Parkinson’s Disease.

According to the motion, filed April 7 by the Texas-based Fears Nachawati law firm with the U.S. Judicial Panel on Multidistrict Litigation, there are currently at least 14 lawsuits filed by eight different law firms in six different federal courts across the country. The lawsuits are all filed on behalf of plaintiffs who have been diagnosed with the neurodegenerative disorder, and they allege exposure to Syngenta’s weed killers made with a chemical called paraquat for the disease. Several other cases making the same allegations are pending in state courts.

“The cases are excellent candidates for coordinated pretrial proceedings because they arise from the same poisonous toxin causing the same crippling disease resulting from the wrongful conduct of the same three defendants,” the Fears Nachawati brief in support of its motion states. “Movant expects that the number of similar cases filed in state and federal courts across the country will expand rapidly.”

The motion seeks transfer specifically to Judge Edward Chen in the U.S. District Court for the Northern District of California.

Majed Nachawati, a partner with the Fears Nachawati firm, said the firm was still investigating the size and scope of the overall litigation but believes the paraquat litigation against Syngenta “will be significant and material in nature…”

“Very soon, there is going to be litigation in dozens of federal courts across the country,” Nachawati said.

The plaintiffs’ lawyers will be seeking internal corporate documents as well as depositions of corporate officials related to the “testing, design, labeling, marketing, and safety of paraquat herbicides,” along with corporate research and evaluations of the toxicity and safety of its paraquat products.

The Miller Firm of Virginia, which helped lead the Roundup cancer litigation against Monsanto that resulted in an $11 billion settlement with Monsanto owner Bayer AG, is among the law firms joining in the paraquat litigation. The Miller firm supports the effort to consolidate the federal actions in California, where thousands of Roundup cases were also consolidated for pretrial proceedings, according to the firm’s lead attorney Mike Miller.

“We are confident that science strongly supports the causal connection between paraquat and the devastation of Parkinson’s disease,” Miller said of the motion. “The Northern District of California is well equipped to handle these cases.”

The cases against Syngenta also name Chevron Phillips Chemical Co. as a defendant. Chevron distributed and sold Gramoxone paraquat products in the United States starting with an agreement with a Syngenta predecessor called Imperial Chemical Industries (ICI), which introduced paraquat-based Gramoxone in 1962. Under a license agreement, Chevron had the right to manufacture, use, and sell paraquat formulations in the U.S.

Syngenta and Chevron have denied the allegations.

Syngenta says that its paraquat products have been approved as “safe and effective” for more than 50 years and it will “vigorously” defend the lawsuits. Syngenta is owned by China National Chemical Corporation, known as ChemChina.

Scientific studies

Parkinson’s is an incurable progressive disorder that affects nerve cells in the brain, leading in advanced cases to severe physical debilitation and often dementia. Many Parkinson’s experts say the disease can be caused by a range of factors, including exposure to pesticides such as paraquat, as well as other chemicals.

Several scientific studies have linked paraquat to Parkinson’s, including a large study of U.S. farmers jointly overseen by multiple U.S. government agencies. That 2011 research reported that people who used paraquat were twice as likely to develop Parkinson’s disease as people who did not use it.

“Numerous epidemiological and animal studies have linked paraquat to Parkinson’s disease,” said Ray Dorsey, a professor of neurology and director of the Center for Human Experimental Therapeutics at University of Rochester in New York. Dorsey is also the author of a book about prevention and treatment of Parkinson’s Disease.

“The evidence linking paraquat to Parkinson’s disease is probably the strongest of any pesticide commonly used,” he said.

Some studies have not found any clear links between paraquat and Parkinson’s and Syngenta asserts that the most recent and authoritative research does not show a connection.

Indeed, a study published in 2020 found connections between some other pesticides and Parkinson’s, but no strong evidence showing paraquat causes the disease.

Upcoming trial

One case filed in a state court is scheduled to go to trial next month. Hoffman V. Syngenta is slated for trial May 10 in St. Clair County Circuit Court in Illinois. A status conference is scheduled for the end of this month.

Missouri lawyer Steve Tillery, who is representing the plaintiffs in the Hoffman case as well as several other plaintiffs in other paraquat lawsuits, said despite Syngenta’s assertions to the contrary, he has accumulated evidence that includes internal company records showing Syngenta has known for decades that its product causes Parkinson’s Disease.

“They shouldn’t be selling this product, said Tillery. “This chemical should be off the market.”
