Latest Roundup Lawsuit Update 2024

February 5th, 2024: Appeals Court Decision Against Bayer in Roundup Cancer Lawsuit

In a pivotal development on February 5, 2024, the 11th U.S. Circuit Court of Appeals refused to dismiss a lawsuit filed by Dr. David Carson, a Georgia doctor who claims Bayer AG’s Roundup weedkiller caused his cancer. This ruling represents a significant setback for Bayer, which has been embroiled in legal challenges concerning Roundup since its acquisition of Monsanto in 2018. Dr. Carson, who alleges that three decades of Roundup use led to his diagnosis of malignant fibrous histiocytoma, adds to the more than 50,000 similar lawsuits Bayer faces, with the majority linking Roundup to non-Hodgkin’s lymphoma.

The court’s decision undermines Bayer’s defense strategy, which argued that federal regulatory approval exempted the company from state law claims regarding failure to warn about Roundup’s risks. This aligns with other appeals courts’ findings in similar cases, further complicating Bayer’s legal position. The company had hoped for a favorable Supreme Court ruling to limit its liability from Roundup litigation, but the Supreme Court has consistently rejected Bayer’s appeals, keeping the door open for ongoing and future lawsuits.

David Frederick, Dr. Carson’s attorney, expressed gratification at the court’s rejection of Monsanto’s defense, emphasizing the significant harm caused by Roundup. Despite winning 10 of the last 16 trials, Bayer has faced over $4 billion in jury verdicts in lost cases since October, with some awards likely to be reduced on appeal as they exceed U.S. Supreme Court guidelines. This latest ruling signals continued legal challenges for Bayer over Roundup’s safety and its impact on consumers’ health.

January 30th, 2024: Philadelphia Jury Awards $2.25 Billion Verdict Against Monsanto and Bayer

In an unprecedented judgment, a Philadelphia jury has ordered Monsanto and its parent company, Bayer, to pay $2.25 billion to John McKivison, a 49-year-old man diagnosed with non-Hodgkin’s lymphoma. McKivison alleged that his cancer was a result of two decades of Roundup usage on his property. This historic verdict, delivered in the Philadelphia Common Pleas Court, includes $2 billion in punitive damages and marks a significant moment in the ongoing legal battles over Roundup. The jury’s decision underscores the view that Roundup is a defective product, highlighting Monsanto’s negligence and failure to warn about the herbicide’s dangers.

Monsanto’s History of Controversy and Bayer’s Stance on Appeal

The verdict is seen as a condemnation of Monsanto’s five decades of misconduct and its reckless disregard for human safety, directly linking it to McKivison’s cancer. Despite Bayer’s intention to appeal the verdict, arguing the damages are “unconstitutionally excessive,” this case adds to the growing list of legal challenges faced by the company since its acquisition of Monsanto in 2018. Bayer maintains that Roundup is safe for use and not carcinogenic, a stance supported by certain regulatory assessments but contradicted by the 2015 World Health Organization report which classified glyphosate, Roundup’s active ingredient, as “probably carcinogenic to humans.”

The Broader Impact and Ongoing Legal Challenges

This verdict represents not just a victory for John McKivison but also signifies the broader legal and public health implications surrounding the use of glyphosate-based herbicides. With over $10 billion already paid out in settlements to cancer patients and their estates, Bayer faces a continuing struggle in the court of public opinion and the legal system. While the EPA and European Commission have found no substantial risks associated with glyphosate, the American Cancer Society notes ongoing research into its link to non-Hodgkin lymphoma. As Bayer prepares for its appeal, the legal landscape for Roundup remains fraught with uncertainty, reflecting the ongoing debate over the safety of glyphosate and its impact on human health.

November 3rd, 2023: Bayer Faces $332 Million Judgment in Roundup Cancer Trial

In a landmark decision, a California jury has awarded a staggering $332 million to Mike Dennis, a 57-year-old man from Carlsbad, who attributed his cancer to long-term use of Monsanto’s Roundup weedkiller. The San Diego Superior Court jury’s verdict came as a significant blow to Bayer, the parent company of Monsanto.

Mike Dennis, diagnosed with a rare form of non-Hodgkin’s lymphoma in 2020, filed the lawsuit asserting that his illness was linked to the active ingredient glyphosate in Roundup. Despite being in remission for nearly three years, his attorney, Adam Peavy, highlighted the grim prognosis from doctors, indicating a potential recurrence of the cancer.

The jury concluded that Monsanto, now a division of Bayer, failed to adequately warn of Roundup’s risks. However, the jury also partially sided with Bayer, ruling that the product’s design was not defective and the company wasn’t negligent.

Dennis received $7 million in compensatory damages and an additional $325 million in punitive damages. Bayer, challenging the verdict, stated to KNSD-TV that it intends to appeal, citing “significant and reversible legal and evidentiary errors” in the trial.

February 22nd, 2023: Bayer AG Ask U.S. Court of Appeals to Reverse 2019 Roundup Ruling

Bayer AG asked a U.S. Court of Appeals to reverse a 2019 ruling that a Pennsylvania man’s Roundup cancer lawsuit was not preempted by a federal labeling law that governs Roundup weedkiller. The Plaintiff in that case alleges that he developed non-Hodgkin’s lymphoma as a result of prolonged exposure to glyphosate, the main active ingredient in Roundup weedkiller products.

Bayer AG filed an appeal on February 8th arguing that a district court in Pittsburgh misinterpreted the Federal Insecticide, Fungicide, and Rodenticide Act or FIFRA. FIFRA expressly preempts any state law that requires a label that is different from federal requirements, and due to the fact that the EPA “has repeatedly determined that glyphosate does not cause cancer and that no cancer warning is required under FIFRA,” Monsanto said, “a state-law requirement to provide such a warning is both ‘in addition to’ and ‘different from’ federal requirements.”

February 9th, 2023: 11th Circuit Court of Appeals will Review Roundup Cancer Case

Bayer and its defense team are continuing to attempt to have Roundup claims dismissed despite the Supreme Court refusing to hear its appeal to dismiss legal action involving the popular herbicide in June 2022.

The 11th Circuit Court of Appeals will review its previous ruling in an en banc rehearing.  Their prior  that deals with the issue of whether federal pesticide law takes precedence over state failure-to-warn claims. Though the rehearing is a win for Bayer, it does not guarantee that the decision will be different or that the Roundup Lawsuits will be dismissed in the near future.

January 19th, 2023: Bayer sued for barring non-U.S. citizen from Roundup settlement

On Thursday January 19th, 2023, a new lawsuit was filed accusing Germany’s Bayer AG of illegally excluding a Virginia farmworker from a Roundup settlement because she is not a U.S. citizen.

The complaint, brought by Elvira Reyes-Hernandez, alleged that Ms. Reyes-Hernandez used Roundup while working on tree farms before being diagnosed with non-Hodgkin’s lymphoma in 2019. She expected to share in a $412.8 million settlement with an average $120,000 payout but Bayer dismissed her from the settlement because of her Mexican citizenship in July 2021.

The lawsuit seeks unspecified damages and a requirement that Bayer let non-U.S. citizens, who comprise more than 70% of agricultural crop farmworkers, join in future Roundup settlements.

June 25th, 2022: U.S. Supreme Court Reject’s Bayer’s Appeal

The U.S. Supreme Court rejected Bayer AG’s bid to dismiss litigation alleging that its Monsanto Roundup weedkiller causes cancer.  The Supreme Court Justices turned away a lower court decision upholding an $87 million judgment awarded in a lawsuit in California to Alberta and Alva Pilliod who were diagnosed with cancer, non-Hodgkin’s lymphoma, after spraying Roundup for more than three decades.

Earlier this year on June 21st, 2022, the U.S. Supreme Court rejected Bayer’s appeal of a $25 million damage award to California resident Edwin Hardeman who also developed non-Hodgkin’s lymphoma after using Roundup as a weedkiller to treat poison oak, overgrowth, and weeds at his home in San Francisco..

Bayer had been pinning their hopes to avoid future Roundup claims and future litigation on the U.S. Supreme Court overturning one of the two weed killer lawsuit appeals.  Now that those appeals have turned down by the Supreme Court, it should allow future Roundup Lawsuits to continue to be brought and it will hopefully open up settlement talks on the remaining claims.

Recent Roundup Verdicts

There have been several high-profile Roundup cases. A few of the most well-known Roundup cases include:

Johnson v. Monsanto – 2018 – In the landmark Roundup case, a California groundskeeper who developed non-Hodgkin lymphoma after years of using Roundup was awarded $289 million in damages after a jury trial. This is the landmark Roundup case because was the first case to go to trial arguing that glyphosate causes cancer.
Pilliod v. Monsanto – 2019 – In one of the largest jury awards, a California couple who both developed non-Hodgkin lymphoma after using Roundup for decades was awarded $2 billion in damages after a jury trial.
Baum Hedlund Aristei & Goldman v. Monsanto – 2019 – In this case, a group of more than 11,200 plaintiffs who claim to have developed non-Hodgkin’s lymphoma as a result of exposure to glyphosate in Roundup agreed to a $10 billion settlement with Monsanto.
Hardeman v. Monsanto – 2019 – In this case, a California man who used Roundup for years on his property was awarded $80 million in damages by a jury, including $75 million in punitive damages.

As the Roundup litigation was commencing Bayer AG, a German pharmaceutical and chemical company acquired Monsanto in 2018. The $63 billion acquisition made Bayer the world’s largest producer of seeds and pesticides. The acquisition was met with some opposition due to concerns about Monsanto’s history of producing controversial products such as Roundup and its active ingredient glyphosate.

Bayer, the German pharmaceutical and chemical company, has faced numerous lawsuits over its glyphosate-based herbicide Roundup, which has been linked to cancer.  As of February 2023, Bayer is still facing tens of thousands of lawsuits alleging exposure to Roundup caused the plaintiffs to develop non-Hodgkin’s lymphoma. Bayer has consistently disputed these complaints defended the safety of Roundup. Throughout the litigation Bayer has argued that the science behind the claims of a link between glyphosate and cancer is inconclusive. However, they have agreed to settle some of the lawsuits for billions of dollars, although they have not admitted any wrongdoing.  Despite the fact that Bayer is disputing liability, individual plaintiffs continue to sue and the Roundup cases continue to pile up. If you have been exposed to Roundup and have suffered harm, such as being diagnosed with non-Hodgkin’s lymphoma, as a result it is in your best interest to consult with a lawyer who focuses their practice in toxic exposure cases.

Do I Qualify for the Roundup Lawsuit?

Individuals who have been diagnosed with non-Hodgkin’s lymphoma or other cancer and believe that their illness was caused by their exposure to Roundup may be eligible to file a Roundup cancer lawsuit.

To qualify for a Roundup lawsuit, an individual plaintiff must:

  1. Be able to prove that they were regularly exposed to Roundup,
  2. Be able to prove that the exposure was a significant factor in the development of their non-Hodgkin’s lymphoma, and
  3. Be able to prove that Bayer failed to adequately warn of the risks associated with using Roundup.

It is important to note that each claim is unique and the specific qualifications for filing a claim vary depending on a number of different factors including the jurisdiction in which the lawsuit is being filed, the individual’s personal circumstances and medical diagnosis, and the scientific evidence available to support the link between Roundup and cancer.

What is Roundup?

When Roundup hit the market in the 1970’s it was a revolutionary new herbicide. It contains the active ingredient glyphosate which is one of the most widely used herbicides in the world. Recent research has produced conflicting evidence as to whether these glyphosate-based pesticides cause cancer in people exposed to them.

Roundup is the brand-name herbicide that contains the active ingredient glyphosate. Monsanto, an American agricultural chemical company, first sold the herbicide commercially in 1974. German drug and chemical giant Bayer acquired Monsanto in 2018 and began phasing out the Monsanto company name. But Bayer continues to make and market Roundup. Initially developed and marketed for large-scale farming operations, Roundup is now available in home and garden versions and has become a popular household weed killer among consumers.

In 2015, a United Nations agency listed the active ingredient in Roundup as “probably carcinogenic.” The announcement set off a controversy over whether a link between Roundup and cancer exists. Then in 2017, the United States Environmental Protection Agency issued a draft report that concluded glyphosate, the main ingredient in Roundup, is safe and “not likely” to cause cancer in humans. The EPA is still reviewing data on the herbicide to determine whether it is a harmful product.

Does Roundup Cause Cancer?

Glyphostate is the active ingredient found in Monsanto’s Roundup weed killer product. Exposure to the active ingredient glyphosate has been linked to chromosomal and DNA damage in human cells, as well as non-Hodgkin’s lymphoma and other types of hematopoietic (blood cell-related) blood cancer. For this reason, more than 25 countries have banned or restricted the use of glyphosate.

The IARC in 2015 announced that the chemical is “probably carcinogenic to humans” which means it carries a risk of cancer. It based its conclusion on tests that showed glyphosate causes DNA and chromosomal damage in human cells, which can lead to cancer.

Exposure to glyphosate weed killers, including Bayer Roundup, have been linked to non-Hodgkin’s lymphoma. In some cases, forms of cancer can spread to other parts of the lymphatic system and in other cases spread to other organs in the body. Some signs and symptoms of non-Hodgkin’s lymphoma may including:

  • Painless, swollen lymph nodes in your neck, armpits, or groin
  • Abdominal pain or swelling
  • Chest pain, coughing, shortness of breath or trouble breathing
  • Persistent fatigue
  • Night sweats
  • Fever
  • Unexplained weight loss

What is the deadline to file a Roundup claim?

The deadline to file a Roundup weedkiller lawsuit varies by State. Each State has a specific statute of limitations for product liability lawsuits. The filing deadline in most states ranges from one to six years for lawsuits involving injuries caused by a defective or dangerous product. You should speak with an experienced products liability lawyer to review your individual situation and your State’s specific state of limitations as it relates to a potential Roundup claim. Definitely do not forego a claim without getting free case analysis from a Roundup lawyer. Waiting too long to bring a Roundup claim could lead to your lawsuit being dismissed and receiving no financial compensation, regardless of whether or not Roundup is responsible for your injuries.

What are the Potential Roundup Settlement Amounts?

Roundup lawsuit settlement values vary widely. Highly publicized jury verdicts include the following:

  • $2.055 Billion Monstanto verdict in Pilliod v. Monstanto Company on May 13th, 2019
  • $289.2 Million Monsanto verdict in Johnson v. Monsanto Company on August 10th, 2018
  • $80 Million Monsanto verdict in Hardeman v. Monsanto Company on March 27th, 2019

It is important to remember that no lawyer can ever guarantee any result when it comes to settlements and verdicts. Not all claimants will receive compensation, and specific Roundup settlement amounts depend on many different factors including the unique facts and circumstances of each case.

According to information reported by the New York Times, individuals who claim that exposure to Roundup sold by Bayer AG and Monsanto caused their non-Hodgkin’s lymphoma or other type of cancer MAY receive settlements between $5,000 and $250,000. The exact amount of compensation awarded, according to the NYT article, will depend on the strength of the claim against Monsanto and some claimants will not receive any compensation. With the help of a skilled Roundup lawyer, you will be able to improve your chances of a favorable Roundup settlement or jury verdict in the District Court.
