The legal activities surrounding Roundup weed killer continued to shift in 2025. With tens of thousands of lawsuits still pending and significant legislative changes on the horizon, 2025 represented a pivotal year in the ongoing battle for justice and corporate accountability.
Overview of Roundup and Ongoing Legal Battles
Roundup, manufactured by Monsanto (owned by Bayer since 2018), has become one of the most controversial herbicides in history. Mounting evidence suggests that glyphosate exposure may significantly increase cancer risk, particularly non-Hodgkin lymphoma.
Since Bayer acquired Monsanto, the company has faced an avalanche of litigation. While Bayer has settled almost 100,000 claims for approximately $11 billion, more than 60,000 active cases remain pending as of November 2025. Over 4,000 cases are consolidated in the federal Multidistrict Litigation (MDL) in the Northern District of California, though the legal battlefield has shifted toward state courts where plaintiffs have achieved substantial victories.
Key Roundup Lawsuit and Legislative Updates for 2025
Record-Breaking $2.1 Billion Georgia Verdict
In March 2025, a Georgia jury awarded John Barnes over $2.1 billion, which was the largest single-plaintiff injury verdict in Georgia history. Barnes developed non-Hodgkin's lymphoma after using Roundup for two decades. The verdict included $65 million in compensatory damages and $2 billion in punitive damages. Bayer reached a confidential settlement with Barnes in November 2025, avoiding the appeals process.
Missouri and Pennsylvania Appellate Victories
In May 2025, a Missouri appellate court affirmed a $611 million verdict against Monsanto. When the Missouri Supreme Court declined to hear Bayer's appeal in October 2025, this represented a major victory for plaintiffs. Similarly, the Pennsylvania Superior Court denied Monsanto's appeal of a $177 million verdict, demonstrating that higher courts are increasingly upholding jury verdicts.
Supreme Court Petition on Federal Preemption
The most consequential development came in April 2025, when Bayer filed a petition asking the U.S. Supreme Court to decide whether federal law preempts state failure-to-warn claims. In June 2025, the Supreme Court invited the U.S. Solicitor General to weigh in. In December, Solicitor General D. John Sauer filed an amicus brief urging the Court to grant certiorari and resolve the circuit conflict over the scope of the federal preemption. If the Supreme Court rules in Bayer's favor, it could effectively end thousands of pending lawsuits. A decision is expected by June 2026.
New Jersey Multicounty Litigation
In June 2025, the New Jersey Supreme Court approved the consolidation of all Roundup cases in the state under one judge in Bergen County, using a process similar to the federal Multidistrict Litigation (MDL) consolidation, called Multicounty Litigation (MCL). This consolidation will streamline pretrial proceedings and increase pressure on Bayer to negotiate settlements.
Bayer Increases Litigation Reserves
In August 2025, Bayer added $1.37 billion to its litigation reserves, bringing the total set aside for Roundup-related liability to approximately $5.9 billion. This demonstrates the company's capacity to continue fighting cases or settling claims.
State Legislation to Shield Pesticide Companies
Throughout 2025, Bayer lobbied state legislatures to pass laws shielding the company from failure-to-warn lawsuits. As of November 2025, Georgia and North Dakota have enacted such legislation. However, Bayer faced defeats in Iowa, Missouri, and Idaho, where bills failed after strong public opposition. Bills remain pending in other states.
Bayer's Market Withdrawal Warning
In April 2025, Bayer warned it may withdraw Roundup from the U.S. market unless it receives legal protection. Critics contend this is a pressure tactic, given that Roundup generates approximately $2.8 billion in annual revenue.
Ongoing Legal Actions and Court Milestones
The federal MDL in California continues with over 4,000 active cases as of November 2025. However, the shift to state courts has proven advantageous for plaintiffs, with juries demonstrating willingness to award substantial verdicts when presented with internal Monsanto documents showing the company's knowledge of alleged cancer risks.
While Bayer claims to have won 17 of the last 25 Roundup trials, significant plaintiff victories continue. Appellate courts have reduced some damages awards, citing constitutional limits on punitive damages, though major verdicts are increasingly being affirmed on appeal or settled.
What These Updates Mean for Consumers and Plaintiffs
The developments in 2025 present both opportunities and challenges. Substantial jury verdicts demonstrate that juries continue finding merit in plaintiff claims, and Bayer's litigation reserves suggest a willingness to resolve cases. However, the pending Supreme Court petition could effectively end many lawsuits if decided in Bayer's favor, and state legislation threatens to close courthouse doors in multiple jurisdictions.
For individuals considering filing a Roundup lawsuit, time is critical. Statutes of limitations vary by state, and with potential Supreme Court and legislative changes, potential plaintiffs should consult experienced attorneys to understand all options.
Early 2026 will be pivotal. If the Supreme Court grants review, a decision is expected by June 2026. Regardless of the outcome, trials will continue in state and federal courts, and Bayer's stated goal of "significantly containing" litigation by the end of 2026 suggests increased settlement pressure.
