While the engineered stone silicosis cases move through state courts, a bill in Congress would end them. H.R. 5437, the Protection of Lawful Commerce in Stone Slab Products Act, would bar civil actions against manufacturers and sellers of stone slab products for harm resulting from a fabricator’s alteration of the product — and would dismiss the actions already pending on the day it became law. It was introduced on September 17, 2025 by Representative Tom McClintock of California, referred to the House Judiciary Committee, and aired at a subcommittee hearing in January 2026. It is not law, and nothing about it changes a deadline that is already running.
What the bill says
H.R. 5437 of the 119th Congress, the Protection of Lawful Commerce in Stone Slab Products Act, would prohibit civil actions against a manufacturer or seller of a stone slab product for harm resulting from the alteration of that product by a fabricator. It was introduced on September 17, 2025 and referred to the Committee on the Judiciary (Congress.gov).
Two features of that drafting matter more than the title. The first is the alteration premise: the slab is sold intact, a fabricator cuts it, and the bill treats the cutting as the intervening act that ends the manufacturer’s exposure to suit. The second is retroactivity — the bill would not merely bar future claims but dismiss pending ones.
Where it has been
A House Judiciary subcommittee took testimony on January 14, 2026 at a hearing titled “Between a Rock and a Hard Place: Protecting the US Stone Slab Industry from Lawfare.” Witness statements filed for that hearing are on the House’s own document server, including one submitted in opposition (witness statement, House Judiciary).
The name is not an accident. It tracks the Protection of Lawful Commerce in Arms Act, the 2005 statute that barred most civil actions against firearms manufacturers and sellers (15 U.S.C. § 7901 et seq.). That is the template industry is asking Congress to reuse.
What it would leave a worker
If the manufacturers and distributors cannot be sued, what remains for a fabricator with scarred lungs is generally a workers’ compensation claim against the employer. Compensation systems pay without proof of fault, which is their virtue, and they are capped, schedule-driven and administered — which is the trade. For a worker in their forties facing a lung transplant, the difference between the two systems is not academic.
- Product claims reach the companies that designed, marketed and supplied the slab; comp claims generally do not.
- Comp recoveries are limited by statutory schedules rather than by what a jury finds the loss to be.
- Where an employer has no insurance or no longer exists, the comp route can be thin.
- Claims against respirator or tool manufacturers are a separate question the bill’s stone-slab framing does not obviously reach.
Why the alteration premise is the argument
Product cases against slab manufacturers do not usually claim the slab was dangerous sitting on a rack. They claim it was dangerous when used the way everyone knew it would be used — cut, ground and polished to fit a kitchen — and that the companies selling it knew what the dust did. A bar keyed to the fabricator’s alteration answers that by treating the cutting as someone else’s act.
Whether Congress adopts that framing is a legislative question, not a medical one. But it is the reason the bill is written the way it is, and the reason its supporters and opponents spent a subcommittee hearing arguing about who in the supply chain knew what.
What to do about a pending bill: nothing
A bill that has had one subcommittee hearing is a long way from being law, and predicting its path is not our job. The point worth making is narrower. Legislation of this kind is a reason to stop waiting, not a reason to wait — because the deadline on a silicosis claim is set by the statute of limitations in the state where the claim belongs, which in most states begins running at diagnosis.
The clock that decides whether a case can be brought is not in Congress. It started at the diagnosis.
It is also worth remembering how bills end. Legislation not enacted before a Congress adjourns does not carry over; it has to be introduced again in the next one. A bill pending in August 2026 is therefore neither law nor settled, and a case that is time-barred by then stays time-barred whatever Congress decides.
If you worked in a fabrication shop and have been diagnosed, the useful next step is to find out what your own record shows. That answer does not depend on what the House Judiciary Committee does next.
This article is general information about how these cases work. It is not legal advice, it does not create an attorney-client relationship, and no two claims are alike. If something here sounds like your situation, the useful next step is a conversation about the facts.
