Silica Exclusion Insurance Coverage Fight: Travelers Seeks to Toss Bedrosians Suit Over 450 Silicosis Cases

Travelers Property Casualty Company of America has asked the U.S. District Court for the Central District of California to dismiss a coverage suit brought by Paragon Industries, Inc., the tile and slab distributor that does business as Bedrosians Tile & Stone, arguing that the silica exclusions in its policies bar coverage for more than 450 personal injury and wrongful death suits filed by stoneworkers. The motion, reported on October 6, 2026, puts one of the largest single blocks of engineered stone silicosis claims into the middle of an unsettled silica exclusion insurance coverage fight that a Los Angeles federal judge has already sent toward the Ninth Circuit.

The dispute matters beyond the two parties. Silicosis plaintiffs have won verdicts as high as $52.4 million against stone manufacturers and distributors, and many of the defendants are mid-sized businesses. Whether their liability insurers must defend and pay is, in practical terms, the question of whether those verdicts and settlements are collectible.

What is the Bedrosians v. Travelers silica coverage lawsuit about?

Paragon Industries filed its complaint on July 2, 2026, in the Central District of California. The case is docketed as Paragon Industries, Inc. v. Travelers Property Casualty Company of America, No. 2:26-cv-07241. Bedrosians sells tile, stone slabs and countertop surfaces, and it has been named as a defendant in a wave of suits by fabrication workers who allege they developed silicosis and related diseases from cutting and finishing stone products.

According to reports of the complaint, Bedrosians seeks defense costs under primary and umbrella commercial general liability policies issued by Travelers. It alleges that Travelers breached the policies and acted in bad faith by relying on the policies' silica exclusion to deny coverage for the majority of roughly 450 underlying bodily injury suits. Those suits allege injury from exposure not only to crystalline silica but also to other substances released when stone products are cut, ground and polished.

That pleading choice is deliberate. In the coverage cases decided so far in Los Angeles, the outcome has turned on whether the underlying complaints allege that silica was the only cause of injury or one of several.

Why did Travelers move to dismiss the Bedrosians coverage suit?

Travelers' position, as reported on October 6, 2026, is that the policies bar coverage for injuries arising from the toxin-exposure allegations in the underlying suits, so Bedrosians cannot state a claim for breach of contract or bad faith. A motion to dismiss tests the pleadings, which means the court will compare the policy language with what the underlying complaints allege, without a factual record about what actually caused any worker's disease.

Silica exclusions are not new. Many liability insurers added them to commercial general liability forms after the silicosis litigation of the early 2000s, and the Insurance Services Office introduced an optional "silica or silica-related dust" exclusion in March 2025. The typical wording removes coverage for bodily injury "arising out of" exposure to silica or silica-related dust. Insurers read "arising out of" broadly: if silica dust is in the causal chain, the claim is out. Policyholders answer that the underlying plaintiffs also blame resins, pigments, metals and volatile organic compounds, so the suits are at least potentially covered.

The judge assigned to the Bedrosians case, the hearing date, and the policy years at issue were not available in public reports at publication. The motion's chances depend heavily on whether the case lands before, or is treated consistently with, the judge who has written most of the existing silica exclusion orders.

How big is the engineered stone silicosis litigation?

The public health numbers explain the claim volume. The California Department of Public Health, reporting in NEJM Evidence, identified 592 cases of silicosis among workers fabricating engineered stone countertops from January 2019 through June 2026. Of those workers, 31 died and 65 underwent lung transplants. The median age at diagnosis was 46, nearly all patients were men, and 98% were Latino. Engineered stone slabs, often marketed as quartz, can contain 90% or more crystalline silica, compared with far lower concentrations in natural granite or marble.

On the litigation side, where silica exclusion insurance coverage determines who funds the defense, a Simpson Thacher analysis published in May 2026 counted more than 400 lawsuits nationwide alleging stoneworker exposure, a figure the Bedrosians complaint alone now matches for a single defendant. Insurers have filed their own declaratory judgment actions in California and Texas, and Bloomberg Law counted at least eight coverage disputes pending in the Central District of California alone.

Underlying silicosis verdicts that frame the coverage fight

Verdict	Date	Court	Result
Gustavo Reyes-Gonzalez	August 2024	Los Angeles County Superior Court	$52.4 million against three manufacturers
Tyler Jordan	May 2026	Colorado state court	About $17 million in damages; Cambria assigned roughly 32% fault, the worker's family fabrication shop more than 60%; complete defense verdict for Caesarstone on May 5, 2026
Wilmer Ruben Martinez Paredes estate	August 3, 2026	Los Angeles County Superior Court (Santa Monica)	$47,035,380 against two Dal-Tile entities, including $45 million in noneconomic damages
Gerardo Ramirez-Soriano estate	August 19, 2026	Orange County Superior Court	$7.1 million

The Colorado result shows the defense theory that drives both the tort cases and the coverage cases: manufacturers and distributors argue that the injury comes from unsafe cutting practices at fabrication shops that ignore OSHA and Cal/OSHA controls. Juries have accepted that argument in part, apportioning fault to the shop, but have still returned large awards against the slab suppliers.

Does a silica exclusion bar coverage for engineered stone silicosis lawsuits?

Not automatically, at least at the pleading stage under California law, which is why silica exclusion insurance coverage has become a contested issue rather than a settled one. The leading federal rulings come from Judge Mónica Ramírez Almadani of the Central District of California, who handles several of the stone coverage cases. In an earlier ruling on the pleadings she read "arising out of" silica language broadly and suggested it would sweep in injuries from other substances released during fabrication. In a later series of orders in separate disputes between stone companies and their insurers, including units of Travelers and Nationwide, she reversed course and held that the exclusions did not unambiguously bar coverage.

The key line, as reported by Bloomberg Law, is that the fact that silica and silica-related dust "are alleged to be a concurrent cause of the underlying plaintiffs' injuries does not relieve [the insurer] from its duty to defend." The Simpson Thacher review reached the same conclusion across state and federal courts: California courts have generally declined to dismiss stone manufacturers' and distributors' coverage actions at the pleadings stage.

That result tracks three established California rules:

• The duty to defend is broader than the duty to indemnify. Under Gray v. Zurich Insurance Co. (1966) and Montrose Chemical Corp. v. Superior Court (1993), an insurer must defend whenever the underlying complaint reveals a potential for coverage, and doubts are resolved in favor of the insured.
• Exclusions are read narrowly. In MacKinnon v. Truck Insurance Exchange (2003), the California Supreme Court confined the standard pollution exclusion to conventional environmental pollution. Insurers invoking the total pollution exclusion against stoneworker claims must show the suits allege that kind of contamination, which Pillsbury's analysis of the pending motions identified as a contested question.
• Mixed actions are defended in full. Under Buss v. Superior Court (1997), an insurer that owes a defense on some claims must defend the whole action, with a possible right to reimbursement later for defense costs allocable solely to claims that were never potentially covered.

What is the concurrent causation argument in silica coverage disputes?

The concurrent causation doctrine, rooted in State Farm Mutual Automobile Insurance Co. v. Partridge (1973), holds that in third-party liability policies coverage can exist where an injury results from both a covered and an excluded cause. Policyholders argue that because stoneworker complaints blame silica together with resins, metals and other constituents, a silica exclusion cannot defeat the duty to defend.

Insurers respond with anti-concurrent causation language, wording that excludes an injury caused by silica "regardless of any other cause" contributing to it. Whether that language can contract around Partridge in a liability policy is the open question. On September 1 and September 8, 2026, the Central District certified interlocutory appeals in four silica coverage suits, including suits involving Regent Insurance, Pacific Shore and Surface Warehouse, finding "a substantial ground for difference of opinion" under California law between the concurrent causation doctrine and anti-concurrent causation clauses.

How have California federal courts ruled on silica exclusions in stoneworker cases?

The record so far is mixed in procedure but consistent in direction: insurers have mostly lost at the pleadings stage, and the appellate question is now teed up.

Dispute	Court	Development	Status
Paragon Industries (Bedrosians) v. Travelers, No. 2:26-cv-07241	C.D. Cal.	Complaint filed July 2, 2026; 450+ underlying suits; motion to dismiss reported October 6, 2026	Motion pending
Stone companies v. Travelers and Nationwide units	C.D. Cal. (Judge Almadani)	Series of orders holding silica exclusions not unambiguous	Duty to defend found at pleadings stage
Regent Insurance v. Cambria Enterprises	C.D. Cal.	Silica and total pollution exclusions held not to bar coverage for more than 170 suits; July 2026 order refused to certify an appeal	Later certification order reported in September 2026
Sompo America v. LX Hausys America	C.D. Cal.	Sompo's motion to dismiss denied December 2025; motion to certify interlocutory appeal filed February 20	Appeal sought
Four coverage suits (Regent, Pacific Shore, Surface Warehouse)	C.D. Cal.	Interlocutory appeals certified September 1 and 8, 2026	Ninth Circuit petitions
Travelers v. Hyundai L&C USA	C.D. Cal.	Travelers units sued as plaintiffs seeking a declaration of no coverage	Pending
Liberty Mutual v. Wilsonart; Liberty Mutual v. Architectural Surfaces Group	W.D. Tex.	Each insured faces more than 100 silicosis suits	Pending
Colony Insurance v. Architectural Surfaces Group	W.D. Tex.	Additional-insured dispute over hundreds of suits under silica and total pollution exclusions (reported September 4, 2026)	Pending

Insurers have also tested the issue outside California, which matters because Texas and other forums apply different contract interpretation rules and may not follow Partridge. Some disputes have ended quietly: QBE dropped a silica coverage case against Home Depot, and Vicostone USA and Allied Property & Casualty reported a mediated settlement to the Northern District of Texas.

Will the Ninth Circuit decide whether silica exclusions apply?

It may, but not quickly. A certification under 28 U.S.C. § 1292(b) lets a party petition the court of appeals within ten days, and the Ninth Circuit then decides whether to accept the appeal at all. If it accepts, a merits decision on the concurrent causation question would ordinarily take a year or more. The Ninth Circuit could also certify the question to the California Supreme Court, since the issue is one of state insurance law with no controlling decision on anti-concurrent causation wording in a liability policy.

For the Bedrosians case, the practical effect is that the district court may be reluctant to grant a pleadings-stage dismissal on a question it has already labeled reasonably debatable. A stay pending the Ninth Circuit's handling of the certified appeals is a plausible alternative outcome, and insurers in other cases have sought reconsideration of certification rulings as the docket has developed.

Bad faith exposure in the silica exclusion insurance coverage fight

Bedrosians pleads bad faith as well as breach of contract. Under California law, an insurer that unreasonably withholds a defense or benefits can be liable for damages beyond the policy limits, and Brandt v. Superior Court (1985) allows recovery of attorney fees incurred to obtain the withheld benefits. Insurers typically answer with the "genuine dispute" doctrine: a denial based on a reasonable reading of an unsettled policy question is not bad faith. The September certifications help insurers on that point, because a court finding a "substantial ground for difference of opinion" is evidence that the coverage position was at least arguable. The insured's counterargument is that by mid-2026 several orders in the same courthouse had already rejected the insurers' reading of the silica exclusion.

What it means for silicosis plaintiffs and personal injury firms

For claimants' counsel, the coverage fight is a collectability problem that shows up in settlement value long before any appellate ruling.

• Defense funding shapes trial strategy. A distributor defending 450 suits without insurer funding has strong incentives to seek a Global Settlement or to slow-walk discovery. One defended under a reservation of rights behaves differently.
• Pleading choices have coverage consequences. Complaints that allege injury from resins, pigments, metals and organic compounds alongside silica are the reason insurers have struggled to win at the pleadings stage. Firms drafting new stoneworker complaints should expect defense counsel and insurers to scrutinize those allegations.
• Policy discovery is worth the effort. Primary, umbrella and excess towers can carry different exclusion wording across policy years. California law allows discovery of insurance agreements, and the specific wording, including any anti-concurrent causation language, can drive how claims are valued.
• Fault allocation is a parallel risk. The Colorado Jordan verdict assigned more than 60% of fault to the fabrication shop employer, and workers' compensation exclusivity generally bars recovery against that employer in tort. Under California's Proposition 51, noneconomic damages are several only, so the shop's share of noneconomic damages may be uncollectible regardless of how the coverage cases resolve.
• Lien and fund planning. Lung transplant cases carry large medical liens. If insurers ultimately win on the exclusions, recoveries may depend on corporate assets, and in the worst cases on bankruptcy proceedings that would stay claims.

Nothing in the coverage rulings affects a worker's ability to sue. The question is who funds the defense and any judgment.

What it means for insurers, manufacturers and distributors

For carriers, the silica exclusion insurance coverage lesson so far is that a standard silica exclusion, without explicit anti-concurrent causation wording, has not been enough to end a defense obligation at the pleadings stage in California federal court. The Ninth Circuit petitions will decide whether more explicit wording works. Insurers writing new policies for the stone sector are already responding through the ISO optional exclusion and higher pricing that Business Insurance has described as a liability crisis for the industry.

For manufacturers and distributors, coverage counsel are likely to treat the certified appeals as the main event and press for defense funding in the meantime. The industry is also pursuing a legislative route: H.R. 5437, introduced by Rep. Tom McClintock, would bar civil suits against slab manufacturers and sellers for harm caused by alteration of their products and would dismiss pending cases. California has moved the other way with the Silicosis Training, Outreach and Prevention (STOP) Act, SB 20, signed on October 13, 2025 and effective January 1, 2026, which bans dry cutting for high-exposure tasks and classifies silica-related illness as a serious injury.

For fabrication shops, the coverage battle between slab sellers and their insurers increases pressure from another direction: manufacturers and distributors who cannot rely on insurance have every reason to shift blame to the shop through comparative fault and, where available, contractual indemnity claims.

What to watch next in silica exclusion insurance coverage cases

• Bedrosians' opposition to the motion to dismiss and any hearing date in No. 2:26-cv-07241.
• Whether the Ninth Circuit accepts the interlocutory appeals certified on September 1 and 8, 2026, and whether it certifies the question to the California Supreme Court.
• Rulings in the Texas coverage suits brought by Liberty Mutual and Colony, which could create a split in approach between Texas and California law.
• New underlying verdicts in Los Angeles and Orange County, which add pressure on carriers and insureds to settle coverage disputes.
• Movement, if any, on H.R. 5437.

FAQ

What is the Bedrosians v. Travelers silica coverage lawsuit about?

Paragon Industries, doing business as Bedrosians Tile & Stone, sued Travelers on July 2, 2026 in the Central District of California, alleging that Travelers breached its primary and umbrella liability policies and acted in bad faith by using a silica exclusion to deny coverage for most of more than 450 stoneworker silicosis suits.

Why did Travelers move to dismiss?

Travelers argues that the policies' silica exclusions bar coverage for injuries arising from the underlying exposure allegations, so Bedrosians cannot state a claim for breach of contract or bad faith. The motion was reported on October 6, 2026.

Does a silica exclusion bar coverage for engineered stone silicosis lawsuits?

Not automatically under California law. A Central District of California judge has held that silica exclusions do not unambiguously bar the duty to defend when stoneworkers allege silica was one of several causes of injury, though that concurrent causation question has now been certified for interlocutory appeal.

How many engineered stone silicosis cases are there?

The California Department of Public Health counted 592 cases among countertop fabrication workers from January 2019 through June 2026, including 31 deaths and 65 lung transplants. More than 400 lawsuits had been filed nationwide by May 2026, and Bedrosians alone reports more than 450 suits against it.

Will the Ninth Circuit decide the silica exclusion question?

Possibly. The Central District certified interlocutory appeals in four silica coverage suits on September 1 and 8, 2026, on whether anti-concurrent causation clauses override California's concurrent causation doctrine. The Ninth Circuit must first agree to hear them.

What happens to silicosis plaintiffs if a defendant's insurer denies coverage?

Plaintiffs can still sue and win verdicts, but collection depends on the defendant's own assets if insurance is unavailable. Coverage denials tend to lower settlement values, slow resolution, and increase the risk that a defendant seeks bankruptcy protection.
