The Intermediate Court of Appeals of West Virginia ruled on November 10, 2026, that Bayer US, LLC must compensate a former employee, Michael Gardill, for his claim of follicular lymphoma (FL) linked to occupational exposure to harmful chemicals. This decision reverses an earlier order that denied Gardill's claim, highlighting the complexities of workers' compensation cases involving occupational diseases.

The ruling is significant as it underscores the legal standards for proving a causal connection between workplace exposure and health conditions, particularly in cases involving cancer diagnoses. This case may impact how similar claims are evaluated in the future, potentially benefiting workers who suffer from occupational diseases.

Background

Michael Gardill worked for Bayer and its predecessor companies from 1981 until his retirement in 2024. During his employment, he was exposed to various harmful chemicals, including benzene, which has been linked to the development of non-Hodgkin lymphoma (NHL) and specifically follicular lymphoma. Gardill filed a claim for workers' compensation after being diagnosed with FL in 2021, asserting that his illness was a result of his prolonged exposure to these chemicals while working at Bayer.

Initially, the claim administrator rejected Gardill's claim in May 2025, stating there was no causal connection between his disease and his employment. Gardill appealed this decision to the Workers’ Compensation Board of Review, which later reversed the claim administrator’s order on December 11, 2025. The Board ruled that Gardill had established a preponderance of the evidence showing that his occupational exposure to benzene was a contributing factor to his development of FL.

The Ruling

The Intermediate Court of Appeals upheld the Board's decision, affirming that Gardill's claim for compensation should be recognized. The court found no substantial legal errors in the Board's ruling and emphasized that the Board had adequately weighed the evidence presented by both parties. The opinion noted, "Mr. Gardill established by a preponderance of the evidence that his occupational exposures to benzene while working at Bayer were more likely than not a contributing factor in his development of NHL/FL."

Judge Ashley N. Deem presided over the case, and the court's ruling highlighted that the legal standard for proving occupational diseases does not require a claimant to demonstrate that their work was the sole cause of their illness. Instead, it suffices to show that the work exposure was a significant contributing factor. The court also noted that the Board had appropriately considered the qualifications of various expert witnesses in reaching its decision.

Impact

This ruling is expected to have a lasting impact on workers' compensation cases in West Virginia, particularly those involving occupational diseases linked to chemical exposure. It reinforces the notion that workers can successfully claim compensation for diseases that are not solely caused by their employment but are significantly influenced by it. This case may encourage other workers with similar claims to pursue their rights, knowing that the courts will consider the totality of evidence rather than requiring a clear, singular causal link.

Furthermore, the decision may prompt employers to reassess their safety protocols and exposure limits for hazardous substances, as the legal implications of failing to protect workers from harmful chemicals can lead to substantial liability. The ruling also highlights the importance of expert testimony in establishing causation in occupational disease cases, suggesting that courts may favor comprehensive evaluations of exposure histories over isolated air sampling data.

What's Next

While Bayer may consider appealing this decision, the court's ruling currently stands, affirming Gardill's right to compensation. There are no related cases pending that could directly influence this ruling, but the outcome may inspire future litigation regarding occupational health and safety in the workplace.
