Episode 19: Two Prosecutions

Everyone says there were two prosecutions under Britain's 1931 Asbestos Industry Regulations in thirty-seven years of enforcement. Everyone is wrong. The real number is three to four distinct prosecution events — and the way the myth formed reveals an enforcement regime so weak it corrupted even the historical record of itself.

In Episode 19 of Asbestos: A Conspiracy 4,500 Years in the Making, we follow the Merewether Report from published science to political compromise. When Parliament drafted the world's first asbestos workplace regulations, industry representatives held a three-to-two majority on the drafting committee. Workers and trade unions were not invited. The resulting rules replaced Merewether's proposed numerical dust limits with a qualitative "dust datum" — a standard modern reconstruction estimates at roughly 200 times today's permissible exposure limit of 0.1 fibers per milliliter. The regulations excluded laggers, construction workers, shipyard workers, brake and clutch workers, and anyone using asbestos products rather than manufacturing them — leaving the vast majority of exposed workers unprotected.

In this episode:

• How industry objected to medical examinations (too expensive), respirator requirements (workers wouldn't wear them), and restrictions on young workers (they'd lose cheap labor) — every objection about cost, none about whether protections would work
• Arthur Greensmith, a carder at J.W. Roberts in Armley, Leeds — diagnosed with asbestosis in 1939, his company appealed his medical suspension, dead within months of leaving employment in 1943
• UK asbestos production rising 60% in the decade after the regulations were supposed to make things safer — from 250,000 tons in 1930 to 400,000 tons by 1940

Expert perspective: Rod De Llano, Founding Partner at Danziger & De Llano, has spent decades demonstrating in court the gap between what regulations required and what companies actually did. The pattern documented in 1930s Britain — regulations written with industry at the table, enforced with industry's consent — persists in asbestos litigation today.

Key Takeaways

1. The 1931 Asbestos Industry Regulations Were Written by Industry: When Parliament convened a conference on July 8, 1930 to draft the world's first asbestos workplace regulations, six government factory inspectors sat across from seven industry representatives. No workers. No trade unions. No independent medical experts. The sub-committee that wrote the actual regulations gave industry a three-to-two majority over government inspectors.
2. Industry Objections Prioritized Cost Over Safety: Industry raised three objections during the drafting process: medical examinations were too expensive, respirator requirements were impractical because workers wouldn't wear them, and restrictions on young workers would eliminate cheap labor. Every objection concerned cost. None addressed whether the protections would work.
3. The Dust Datum Was 200 Times Today's Safe Limit: Instead of adopting Merewether's proposed numerical dust limits, the regulations used a qualitative "dust datum" — a subjective standard rather than a measurable threshold. Modern reconstruction estimates this datum translated to approximately 20 fibers per milliliter of personal exposure. Today's permissible exposure limit is 0.1 fibers per milliliter, making the 1931 standard roughly 200 times what we now consider safe.
4. The Regulations Excluded Most Exposed Workers: The 1931 regulations only covered "scheduled areas" — specific processes in specific factories. They excluded laggers, construction workers, shipyard workers, brake and clutch workers, automotive workers, anyone working fewer than eight hours per week with asbestos, and anyone using asbestos products rather than manufacturing them. The 1921 Census counted 3,762 people in asbestos manufacturing; by World War Two, 4.5 million American shipyard workers handled asbestos daily with no comparable protection.
5. The "Two Prosecutions" Claim Is Wrong: The widely-cited claim that only two prosecutions occurred under the 1931 regulations between their enactment and 1968 is a myth. Three conflicting accounts exist: Account A (Tweedale/Bartrip) documents two conviction-years in 1935-1936 with five charges and four convictions. Account B (Wikeley) records two firms prosecuted circa 1964 with four counts and £220 in total fines. Account C (Dalton 1979, repeated by others) conflates Accounts A and B into a single soundbite, erasing the 1935-1936 cases entirely. The real total is likely three to four distinct prosecution events.
6. The £12 Average Fine Mystery Solved: Tweedale's Table 9.1 lists an average fine of £12. Bartrip's breakdown reveals the arithmetic: £8 (1935 conviction) + £15 (1936 convictions) = £23 ÷ 2 conviction-years = £11.50, rounded to £12.
7. Company Two Cannot Be Identified: Wikeley's footnote 54 records two firms prosecuted — Central Asbestos Company (£170, three counts, April 1964) and an unnamed second company (£50, one count). Four AI research models searching over 200 sources could not identify Company Two. The physical Annual Reports remain undigitized at the National Archives.
8. Arthur Greensmith's Case Demonstrates Enforcement Failure: Arthur Greensmith, a carder at J.W. Roberts in Armley, Leeds, was diagnosed with asbestosis in 1939. The regulations required his suspension from hazardous work. His company appealed the suspension. He was never properly removed from dusty work, left employment in August 1943, and died within months. J.W. Roberts later admitted in an internal memo that they had "no realistic defence" and had been violating the regulations from at least 1950 onward.

Episode Summary

In 1931, Britain enacted the Asbestos Industry Regulations — the world's first workplace regulations specifically targeting asbestos exposure. The regulations followed directly from the Merewether Report's devastating findings that 80.9% of workers with 20+ years of asbestos exposure developed asbestosis. But the regulatory process was compromised from the start. When Parliament convened a drafting conference in July 1930, industry representatives outnumbered government inspectors, and workers were entirely excluded. The resulting regulations replaced Merewether's proposed numerical dust limits with a subjective "dust datum" roughly 200 times today's safe exposure level. They covered only a narrow slice of the exposed population — workers in scheduled manufacturing processes — while excluding the vast majority of people who would be harmed by asbestos in the decades ahead, including construction workers, shipyard workers, and anyone using asbestos products.

Enforcement was virtually nonexistent. The widely-repeated claim that only "two prosecutions" occurred under these regulations in 37 years is itself a myth that this episode debunks. Three separate, conflicting accounts exist in the historical record — from Tweedale and Bartrip (1935-1936 conviction data), from Wikeley (1964 prosecution data), and from Dalton (1979 conflation). The real total is likely three to four prosecution events, but the myth has been repeated uncritically for over fifty years because no one checked the arithmetic. Meanwhile, UK asbestos production increased 60% in the decade after the regulations — from 250,000 tons in 1930 to 400,000 tons by 1940. The regulations existed so that someone could point to them and say "we're handling it." For forty years, that's exactly what happened.

HOST 1: So. I have something for you.

HOST 2: Okay.

HOST 1: Something everyone knows. Something everyone repeats. Something that turns out to be wrong.

HOST 2: We're myth-busting again.

HOST 1: We are.

HOST 2: Good. The salamander was ridiculous and I enjoyed killing it. What have you got?

HOST 1: I know. But this myth isn't two thousand years old. This one's from 1979. And scholars are still repeating it today.

HOST 2: How wrong are we talking?

HOST 1: Everyone says there were two prosecutions under the Asbestos Industry Regulations between 1931 and 1968. There weren't.

HOST 2: More? Or fewer?

HOST 1: That's the problem. The answer is yes.

HOST 2: Oh, this is going to be one of those episodes.

HOST 1: This is Episode 19. Two Prosecutions.

=== INTRO / SPONSOR BREAK 1 ===

[02:00]

HOST 2: Asbestos: A Conspiracy 4,500 Years in the Making is brought to you by Danziger & De Llano, thirty years of turning corporate records into family justice. Dandell dot com. That's D-A-N-D-E-L-L dot com.

=== SEGMENT 1: THE REGULATIONS ===

[02:30]

HOST 1: So. Last episode, we ended with Merewether and Price. They'd done the work. 80.9 percent of workers with twenty or more years of exposure had asbestosis. Twelve specific recommendations. The science was finished.

HOST 2: And Parliament acted.

HOST 1: Parliament acted. The Asbestos Industry Regulations. March 1931. And now we get to find out what happens when science meets politics.

HOST 2: What always happens.

HOST 1: On June 19th, 1930, Duncan Wilson sends a letter launching the regulatory process. And on July 8th, a conference convenes to shape the new rules. Six government factory inspectors. Seven industry representatives.

HOST 2: And the workers?

HOST 1: Zero. No workers. No trade unions. No independent medical experts. Just the regulators and the regulated.

HOST 2: So the people getting killed weren't invited to the meeting about how to stop killing them.

HOST 1: That's correct. And it gets worse. The conference creates a sub-committee to draft the actual regulations. Price is on it. Ward is on it. And three industry representatives. Industry had a three-to-two majority on the committee writing worker protections.

HOST 2: Who benefits from that composition? Not the workers in the factories.

HOST 1: Industry raised three objections. Medical examinations — too expensive. Respirator requirements — workers wouldn't wear them. And restrictions on young persons working with asbestos — because they'd lose cheap labor.

HOST 2: Every objection is about cost. Not one is about whether the protections would actually work.

HOST 1: Now here's where it gets technical, but stay with me. Merewether had recommended numerical dust limits. Actual measurable thresholds. What the regulations adopted instead was something called a dust datum.

HOST 2: Which was what, exactly?

HOST 1: A vibe check. Not a measurement. The standard was — and I'm quoting — conditions arising from flyer spinning carried out without exhaust under good general conditions.

HOST 2: That's not a standard. That's a sentence.

HOST 1: No number. No threshold. No way to objectively prove a violation. Modern reconstruction suggests that dust datum probably translated to about twenty fibers per milliliter of personal exposure. Today's permissible exposure limit is 0.1 fibers per milliliter. The standard they set was two hundred times what we now consider safe.

HOST 2: Two hundred times. And that was the one they wrote down.

HOST 1: And here's the part that matters most. The regulations only covered scheduled areas. Specific processes in specific factories. They excluded laggers. Construction workers. Shipyard workers. Brake and clutch workers. Automotive workers. Anyone working fewer than eight hours per week with asbestos. And critically — anyone using asbestos products, as opposed to manufacturing them.

HOST 2: So who was actually covered?

HOST 1: The 1921 Census counted 3,762 people in asbestos manufacturing. That's roughly who was protected. By World War Two, four and a half million American shipyard workers were handling asbestos daily. None of them covered by anything resembling these regulations.

HOST 2: They built a fence around a garden and called it flood protection. These regulations weren't broken. They worked exactly as designed.

=== SPONSOR BREAK 2 ===

[10:00]

HOST 2: Speaking of regulations that looked good on paper — Danziger & De Llano has spent thirty years finding the gap between what companies said they did and what they actually did. Dandell dot com.

=== SEGMENT 2: THREE ACCOUNTS — THE PROSECUTION MYTH ===

[10:30]

HOST 1: Now. The number everyone knows. Two prosecutions in thirty-seven years. You'll find it in textbooks. Government reports. Academic papers. It's wrong. And the way it's wrong is genuinely fascinating, because what we actually have are three conflicting accounts that got collapsed into a single soundbite.

HOST 2: Three accounts.

HOST 1: Three. Let's take them one at a time. Account A comes from Tweedale, drawing on the Factory Inspector Annual Reports. His Table 9.1 shows two convictions, with an average fine of twelve pounds. Bartrip breaks it down further — 1935, two charges, one conviction, eight pounds. 1936, four charges, three convictions, fifteen pounds.

HOST 2: Wait. Two different years. Multiple charges. That's already more than the myth suggests.

HOST 1: And that twelve-pound average? It's just arithmetic. Eight plus fifteen equals twenty-three, divide by two conviction-years, you get eleven pounds fifty. Rounded to twelve. Mystery solved.

HOST 2: So the first set of two prosecutions is from 1935 and 1936. A whole four years after the regulations took effect.

HOST 1: Now Account B. This comes from Wikeley, 1992, footnote 54 — buried behind a JSTOR paywall. He records two firms, four counts, total fines of two hundred and twenty pounds. Firm one — Central Asbestos Company, Bermondsey, April 1964. Three counts. Seventy-five, seventy-five, twenty pounds plus ten shillings costs. That's a hundred and seventy pounds.

HOST 2: And firm two?

HOST 1: One count. Fifty pounds. Unnamed.

HOST 2: Unnamed?

HOST 1: The arithmetic tells us everything and nothing. Four counts minus three equals one count. Two hundred twenty pounds minus a hundred seventy equals fifty. We know the fine amount. We know the count. We cannot tell you who was prosecuted.

HOST 2: How is that possible? A company gets prosecuted under asbestos regulations and nobody wrote down the name?

HOST 1: We checked. Four different AI research models searched over two hundred sources. Nobody can name Company Two. Wikeley's footnote cites the Annual Reports, but Central Asbestos never appeared in the Factory Inspector Annual Reports in the first place. These are completely different datasets.

HOST 2: So we have two separate sets of prosecutions from two separate eras that don't overlap at all.

HOST 1: Which brings us to Account C. The version everyone actually repeats. Dalton in 1979. The Environmental and Equality Alliance in 2002. The claim — only two prosecutions between 1931 and 1968. That claim takes Account A and Account B, erases the 1935 and 1936 cases entirely, and conflates everything into a single number that sounds damning but is actually less accurate than the truth.

HOST 2: So the myth isn't just wrong. It's wrong in a way that makes the record look better than it was.

HOST 1: The real total is probably three to four distinct prosecution events across thirty-five years. And nobody checked. For fifty years, everyone cited the same soundbite without asking — two prosecutions from which set?

HOST 2: The enforcement regime was so weak it corrupted even the historical record of itself.

HOST 1: And Company Two. One company. One count. Fifty pounds. Sometime between 1964 and 1970. The physical Annual Reports sit undigitized at the National Archives. We can tell you the arithmetic. We can tell you the fine amount. We cannot tell you who was prosecuted. And that gap is the story. A prosecution so minor it generated no press coverage, no public record, no institutional memory.

HOST 2: A company violated asbestos regulations, got caught, paid fifty pounds, and vanished from history. That's not even a slap on the wrist. That's a shrug.

=== SEGMENT 3: HUMAN COST — ARTHUR GREENSMITH ===

[17:00]

HOST 1: Arthur Greensmith was a carder at J.W. Roberts in Armley, Leeds. Diagnosed in 1939 with early-stage asbestosis. The regulations were eight years old by then. They said he should be suspended from hazardous work. His company appealed the suspension.

HOST 2: The company appealed.

HOST 1: With the worker's approval, they said. He was never properly suspended from dusty work. He left employment in August 1943. Dead within months.

HOST 2: The regulations said protect this man. The company said no. And the enforcement system said nothing.

HOST 1: J.W. Roberts' own internal memo — written years later — admitted they had no realistic defence. They knew they were violating the regulations from at least 1950 onward.

HOST 2: And the industry grew. It didn't contract.

HOST 1: UK asbestos production went from two hundred fifty thousand tons in 1930 to four hundred thousand tons by 1940. A sixty percent increase in the decade after the regulations were supposed to make things safer. Robert Turner — and this is Tier 3, we're working from secondary sources — actually proposed removing asbestos from the dangerous occupations schedule entirely in 1932. Not strengthening protections. Eliminating them.

HOST 2: One year after passing the regulations. One year.

HOST 1: The regulations had a Chief Inspector exemption clause. They had an eight-hour-per-week exclusion. They had qualitative dust standards instead of numerical ones. They had industry on the drafting committee. They had zero prosecution resources.

HOST 2: This wasn't a failure of enforcement. This was enforcement working exactly as designed. The regulations existed so someone could point to them and say — we're handling it.

HOST 1: And for forty years, that's exactly what happened.

HOST 2: Forty years.

=== ARC 5 TEASE ===

[20:00]

HOST 1: Next week. Episode 20. The Less Said About Asbestos, the Better.

HOST 2: That's a quote?

HOST 1: Direct quote. From an executive. To another executive. In writing.

HOST 2: Bold strategy.

HOST 1: They had a lot of bold strategies. Arc 5 begins. The Sumner Simpson letters, 1930 to 1935. What happened when American executives started writing to each other about what they knew, what they were hiding, and why. The conspiracy moves from incompetence to intent.

HOST 2: I look forward to it. And by that I mean I'm already angry.

=== SPONSOR BREAK 3 / CLOSE ===

[21:00]

HOST 1: Before we go. One thing about the team behind this show.

HOST 2: Anna Jackson is the Director of Patient Support at Danziger & De Llano. She spent twelve years in advertising. Her husband died of cancer in 2007. She walked away from everything — the career, the industry, all of it — and joined this fight. Fifteen years now. Helping families through the same nightmare she lived.

HOST 1: That's the kind of team we're talking about. People who understand the law and the loss. Cases in all fifty states. Available seven days a week. Nearly two billion dollars recovered for over a thousand families. Thirty years of doing this work.

HOST 2: Dandell dot com. D-A-N-D-E-L-L. Or call 866-222-9990. If you heard something in this episode that sounded familiar — a job, a factory, a family member who came home covered in dust — that call costs nothing.

=== OUTTAKES ===

HOST 1: I got genuinely excited about solving a rounding error from 1935. Eight plus fifteen, divided by two, rounds to twelve. That was the highlight of my week.

HOST 2: That's the saddest thing you've ever said. And I've listened to all nineteen of these.

HOST 1: It was satisfying though. Forensic accounting.

HOST 2: At least the salamander myth was romantic. This one's just accountants.

HOST 2: Fifty pounds. You know what else cost fifty pounds in 1964?

HOST 1: I'm afraid to ask.

HOST 2: A decent suit. They fined a company less than the cost of burying the workers they killed.

HOST 1: That's dark even for you.

HOST 2: This is a show about corporate murder. I'm calibrated appropriately.

HOST 1: The job.

HOST 2: The job.

Frequently Asked Questions

What were the 1931 Asbestos Industry Regulations?

The Asbestos Industry Regulations of 1931 were the world's first workplace regulations specifically targeting asbestos exposure. Enacted by the British Parliament following the Merewether Report, they required dust suppression measures and medical examinations in scheduled asbestos manufacturing areas. However, the regulations were drafted with industry holding a three-to-two majority on the writing committee, replaced proposed numerical dust limits with a subjective "dust datum," and excluded the majority of workers exposed to asbestos — including construction workers, shipyard workers, and anyone using rather than manufacturing asbestos products.

How many prosecutions actually occurred under the 1931 regulations?

The commonly-cited claim of "two prosecutions" between 1931 and 1968 is inaccurate. Three separate historical accounts exist: Tweedale and Bartrip document two conviction-years in 1935 and 1936 (five charges, four convictions, average fine of £12). Wikeley records two firms prosecuted circa 1964 (four counts, £220 total fines, including Central Asbestos Company in Bermondsey). Dalton's 1979 account conflated these into the "two prosecutions" soundbite that has been repeated ever since. The actual total is likely three to four distinct prosecution events across 35 years.

What was the "dust datum" in the 1931 regulations?

The dust datum was the exposure standard adopted by the 1931 Asbestos Industry Regulations. Rather than establishing a numerical threshold as Merewether had recommended, the regulations defined acceptable conditions as those "arising from flyer spinning carried out without exhaust under good general conditions." This qualitative standard provided no objective measurement for enforcement. Modern reconstruction estimates the dust datum corresponded to approximately 20 fibers per milliliter — roughly 200 times today's permissible exposure limit of 0.1 fibers per milliliter.

Who was Arthur Greensmith?

Arthur Greensmith was a carder at J.W. Roberts in Armley, Leeds who was diagnosed with asbestosis in 1939. Despite the regulations requiring his suspension from hazardous work, his company appealed the medical suspension — reportedly with the worker's own approval. Greensmith was never properly removed from dusty conditions, left employment in August 1943, and died within months. His case illustrates the enforcement vacuum under the 1931 regulations: the rules said to protect him, the company refused, and no enforcement action followed.

What was the Central Asbestos Company prosecution?

The Central Asbestos Company, based in Bermondsey, London, was prosecuted in April 1964 under the Asbestos Industry Regulations. The company faced three counts and was fined a total of £170 (seventy-five pounds on each of two counts plus twenty pounds on a third, with ten shillings in costs). This prosecution, documented by legal scholar Nigel Wikeley, was one of the few enforcement actions taken in over three decades of the regulations' existence.

Why did British asbestos production increase after the 1931 regulations?

UK asbestos production rose approximately 60% in the decade following the regulations — from 250,000 tons in 1930 to 400,000 tons by 1940. The regulations imposed minimal compliance costs, covered only a small fraction of the exposed workforce, and were enforced with near-zero prosecution activity. The industry faced no meaningful economic consequence from the regulatory framework, allowing production to expand without constraint. Robert Turner of Turner Brothers reportedly proposed removing asbestos from the dangerous occupations schedule entirely in 1932 — just one year after the regulations were enacted.

What workers were excluded from the 1931 Asbestos Industry Regulations?

The regulations only covered workers in "scheduled areas" — specific manufacturing processes in registered factories. Explicitly excluded were: laggers (who applied asbestos insulation), construction workers, shipyard workers, brake and clutch workers, automotive workers, anyone working fewer than eight hours per week with asbestos, and all workers who used asbestos products rather than manufactured them. The 1921 Census counted 3,762 people in asbestos manufacturing — roughly the population that was protected. By World War Two, millions of additional workers handled asbestos daily with no regulatory coverage.

Modern Relevance: From 1931 to Today

The pattern documented in 1930s Britain — regulations written with industry participation, enforced with industry's consent, and effective only on paper — is not a historical artifact. In the United States, approximately 3,000 new mesothelioma cases are diagnosed annually, many traceable to exposures that occurred under regulatory frameworks that technically required worker protection but failed to deliver it. The 20-50 year latency period for mesothelioma means that workers exposed decades ago are only now receiving diagnoses.

The 1931 regulations' exclusion of construction workers, shipyard workers, and product users created an exposure gap that persisted for generations. American shipyard workers during World War Two — 4.5 million strong — handled asbestos daily with no regulatory protection comparable even to Britain's inadequate 1931 framework. Today, approximately 30% of mesothelioma patients are military veterans, many of whom served on ships insulated with asbestos during an era when no workplace regulation covered their exposure.

Over $30 billion remains available in asbestos trust funds established to compensate victims of exposures that regulatory frameworks failed to prevent. Danziger & De Llano, the law firm producing this series, has recovered nearly $2 billion for families affected by asbestos exposure over more than 30 years of practice. The firm's work often involves demonstrating in court the same gap this episode documents: the distance between what regulations required and what companies actually did.
