BNSF Railway notched a decisive legal win Tuesday after a federal appeals court overturned a prior finding that the railroad contributed to two asbestos-related deaths in Libby, Montana — a ruling that reshapes one of the highest-profile cases tied to one of America’s worst environmental disasters.
The 9th U.S. Circuit Court of Appeals reversed a lower-court outcome that had allowed a jury to award $4 million each to the estates of two residents who died in 2020. Their families argued asbestos-contaminated vermiculite accumulated in BNSF’s downtown Libby rail yard, spreading toxic dust into the surrounding community.
Instead, the appellate panel sided with BNSF Railway, concluding the company was shielded by federal protections granted to “common carriers” — railroads required to transport goods offered to the public.
Appeals Court: Common Carrier Shield Applies
At the center of the decision is BNSF’s legal status as a common carrier. Under federal law, railroads that serve the general public are generally required to transport lawful freight. The court determined that the alleged hazardous condition — asbestos dust tied to vermiculite shipments — arose from BNSF carrying out that federally mandated duty.
Judge Morgan Christen wrote that BNSF was “protected from strict liability by the common carrier exception,” effectively blocking the theory that allowed the Helena jury to find the company legally responsible for the two deaths.
The ruling reverses one of the first Libby-related cases against BNSF to reach trial, potentially influencing numerous pending lawsuits tied to the town’s contamination legacy.
$8 Million Jury Award Overturned
In 2024, jurors in Montana awarded a combined $8 million in compensatory damages — $4 million per estate. The jury did not find that BNSF acted intentionally or with indifference, meaning no punitive damages were imposed.
Still, the verdict was viewed by plaintiffs’ attorneys as a breakthrough in holding secondary actors accountable for Libby’s asbestos crisis.
Tuesday’s appellate decision wipes that award away, delivering a legal setback for families who had sought broader corporate responsibility beyond the mine operator itself.
The Libby Asbestos Disaster
Libby, a small town near the U.S.-Canada border, became synonymous with asbestos contamination after vermiculite mined from a nearby mountaintop was found to contain high levels of naturally occurring asbestos.
The material was widely used in insulation and construction products across the country. After extraction, vermiculite was transported through the Libby rail yard, where residents said spills and stockpiles created airborne dust that drifted into homes and businesses.
Health officials have linked the exposure to hundreds of deaths and thousands of illnesses. In 2009, the Environmental Protection Agency declared Libby the nation’s first public health emergency under the federal Superfund program — an extraordinary step underscoring the scale of contamination.

W.R. Grace’s Central Role
Much of the historical liability centers on W.R. Grace & Co., the company that operated the vermiculite mine until it shut down in 1990. Grace later declared bankruptcy and paid substantial settlements to victims, though many residents argue the compensation fell short of the damage inflicted.
Federal prosecutors indicted W.R. Grace and executives in 2005 on criminal charges related to contamination. A jury acquitted them in 2009.
BNSF has maintained it was repeatedly told by W.R. Grace representatives that the vermiculite shipments were safe and that it was legally obligated to transport them.
Berkshire Hathaway Connection
BNSF is owned by Berkshire Hathaway, which acquired the railroad in 2010 — two decades after the Libby mine ceased operations. While the acquisition postdated the most active period of shipments, the railroad’s historical operations in Libby remain at the center of ongoing litigation.
For Berkshire, the appeals court ruling reduces immediate legal exposure tied to Libby-related claims, though it does not eliminate all potential lawsuits stemming from the contamination era.
What This Means for Pending Cases
The overturned verdict was considered a test case among numerous suits brought by current and former Libby residents. By reinforcing the legal protections tied to common-carrier status, the ruling may complicate similar claims against BNSF.
Legal analysts note that future plaintiffs may attempt to distinguish their claims by focusing on conduct beyond the narrow duty to transport freight — an argument that will likely face renewed scrutiny following Tuesday’s decision.
For Libby residents, however, the legal back-and-forth continues against a backdrop of long-term health consequences and decades of cleanup efforts.
The appellate ruling underscores a persistent tension in environmental liability cases: when contamination flows through required infrastructure, courts must weigh public-service obligations against community-level harm — a balance that, in Libby’s case, remains legally and emotionally unresolved.
