Introduction
The Roundup weed killer lawsuit has evolved into one of the most consequential mass torts in U.S. legal history. With over 100,000 claims already filed and billions of dollars in settlements paid out, the litigation represents a critical turning point in the battle between public health concerns and corporate accountability. At the center of the dispute is glyphosate, the active ingredient in Roundup, which plaintiffs allege caused non-Hodgkin’s lymphoma (NHL) and other cancers due to prolonged exposure.
Monsanto Roundup’s original manufacturer was acquired by Bayer in 2018. Since then, Bayer has faced mounting legal pressure, scientific scrutiny, and judicial setbacks. For law firms, plaintiffs, and the public, understanding the latest developments is essential. This article covers the most recent court decisions, settlement updates, qualifying criteria, and how Trivent Legal supports law firms involved in this complex litigation.
Roundup Lawsuit Timeline: Latest Developments
March 2024 – Settlement in California
Bayer reached a $6.9 million settlement to resolve multiple individual claims in California state court, separate from the federal MDL. This move was seen as an attempt to resolve lingering state-level liability and reduce case backlog outside the main multidistrict litigation (MDL) forum.
June 2024 – U.S. Supreme Court Declines Appeal
In a significant legal blow to Bayer, the U.S. Supreme Court declined to hear the company’s appeal seeking protection from future claims. Bayer had argued that federal pesticide laws should preempt state failure-to-warn claims. The decision cleared the path for thousands of new lawsuits to move forward.
August 2024 – More Claims Added to MDL
The Roundup MDL in the Northern District of California—overseen by Judge Vince Chhabria—saw an influx of more than 4,000 new cases, further escalating the pressure on Bayer and highlighting the continuing public concern over glyphosate exposure.
October 2024 – $92 Million Bellwether Verdict
A second major bellwether trial resulted in a $92 million jury verdict for a plaintiff diagnosed with non-Hodgkin’s lymphoma. The court cited clear evidence of prolonged exposure and Monsanto’s internal suppression of glyphosate safety concerns. This decision bolstered plaintiffs’ negotiating power in settlement discussions.
January 2025 – Discovery Order Enforced
The court compelled Bayer to release additional internal documents, including safety assessments, marketing communications, and research notes on glyphosate. These disclosures are expected to influence future trials and expert testimonies.
May 2025 – Occupational Exposure Filings Increase
An increase in filings from landscapers, groundskeepers, and farmworkers drew renewed attention to occupational exposure risks. Advocacy groups and legal teams began pushing for updated safety regulations and greater protections for workers in agricultural and landscaping sectors.
What is the Roundup Lawsuit About?
The Roundup lawsuit centers on allegations that exposure to glyphosate caused cancer, particularly non-Hodgkin’s lymphoma. Plaintiffs claim that Monsanto:
- Failed to warn users about the carcinogenic potential of glyphosate
- Misled regulators and consumers by downplaying risks in public messaging
- Manipulated scientific data to avoid stricter regulations
- Marketed the product as safe for widespread home and commercial use
Though the Environmental Protection Agency (EPA) has maintained that glyphosate is safe when used properly, other scientific bodies—such as the World Health Organization’s International Agency for Research on Cancer (IARC)—have classified glyphosate as a “probable human carcinogen.”
Who Can File a Roundup Lawsuit?
Eligibility Criteria Include:
- Regular or Prolonged Use: Especially in occupational settings (groundskeeping, farming, landscaping)
- Cancer Diagnosis: Primarily non-Hodgkin’s lymphoma, but also includes leukemia, B-cell lymphoma, and multiple myeloma
- Proof of Use: Purchase receipts, employer records, or affidavits confirming long-term exposure
- Latency Period: Diagnosis occurred within a medically reasonable time frame following exposure (usually 5–15 years)
Eligible Groups Often Include:
- Agricultural workers and farmhands
- Landscapers and groundskeepers
- Nursery and greenhouse workers
- Homeowners using Roundup regularly over years
- Family members exposed through secondary contact
Survivors of deceased victims may also file wrongful death claims if documentation and timelines support causation.
What Types of Cancer Are Linked to Roundup?
The following cancers have been associated with glyphosate exposure through epidemiological studies and expert witness reports:
- Non-Hodgkin’s Lymphoma (NHL) – The most commonly linked cancer in these lawsuits
- Diffuse Large B-cell Lymphoma
- Chronic Lymphocytic Leukemia
- Multiple Myeloma
- Leukemia (some cases)
- Lung Cancer (less common, with mixed causation evidence)
These are serious, life-altering conditions often requiring chemotherapy, radiation, or long-term immunotherapy. Plaintiffs argue that had they been warned, they could have avoided or minimized exposure.
Roundup Lawsuit Settlements: What Law Firms Should Know
Total Settlements To Date
- Bayer has paid over $10 billion to settle more than 100,000 cases
- Settlements are handled both within and outside of the MDL
- Individual payouts have ranged from $5,000 to over $2 million
Factors That Influence Settlement Value:
- Severity of cancer and treatment outcomes
- Frequency and duration of Roundup use
- Age and health of the plaintiff
- Proof of exposure and employment history
- Future care and income loss projections
Most settlements are structured around point systems based on severity, documentation, and prognosis. Bellwether trials provide benchmarks that drive the overall value of future settlements.
How Long Will Roundup Lawsuits Take to Resolve?
These cases often require 18 to 36 months from filing to resolution, depending on the following:
- MDL scheduling and trial docket movement
- Whether the case proceeds to trial or is settled early
- The quality and completeness of medical and exposure documentation
- Court backlog and judicial resource allocation
Some law firms may opt for early resolution programs if their clients have strong documentation and meet priority criteria.
