Tort Law’s Sleight of Hand – Part 2

August 2nd, 2020

There was sadly no dearth of cases of asbestosis or silicosis before the publication of the Restatement (Second) of Torts. Before 1965, legal doctrine and state and federal regulatory regimes saw the occupational lung disease problem as one of employers’ management of the workplace, and employer and employee compliance with regulations.[1]

Before the Restatement (Second) of Torts in 1965, cases against remote industrial suppliers were quite uncommon. In the first few decades of the 20th century, workers could still sue their employers in tort, and remote suppliers had a robust defense based upon reliance on the purchaser-employers’ obligation to provide a safe workplace. Even after the widespread adoption of worker compensation laws, the common law acknowledged that many “[c]hattels are often supplied for the use of others,” and provided an exception to liability rules based upon the facts and circumstances of the product, its use, the known hazards of its use, and the character of buyer.[2]

By the time of the Restatement (Second), most workplace accidents and injuries, including the development of occupationally related chronic diseases were covered by workers’ compensation statutes, which effectively barred lawsuits directly against employers.[3] Perversely, these statutes also granted employers liens against tort recoveries from remote suppliers, with the consequence of diluting the costs to the employer for failing to prevent injuries and disease the employer was uniquely positioned to avoid.

Section 402A certainly opened the way for applying products liability law to protect the employees of purchasers. Nonetheless, Section 388 of the First Restatement was carried forward to the Second, and arguably qualified the application of 402A, by providing a sophisticated intermediary sophisticated intermediary defense. This defense acknowledged the impossible burden placed upon a product supplier to warn every possible user of its product, especially in the industrial context where purchaser/employers maintain and control the safety of their workplace. Section 388 observed that responsibility for warning employees in many cases must be carried out by purchasers/employers of the product, who are in the best position to warn users/employees.

The language of Section 388 provides important limitations on the scope of Section 402A, from the same Restatement:

Section 388. Chattel Known to Be Dangerous for Intended Use

One who supplies directly or through a third person a chattel for another to use is subject to liability to those whom the supplier should expect to use the chattel with the consent of the other or to be endangered by its probable use, for physical harm caused by the use of the chattel in the manner for which and by a person for whose use it is supplied, if the supplier

(a) knows or has reason to know that the chattel is or is likely to be dangerous for the use for which it is supplied, and

(b) has no reason to believe that those for whose use the chattel is supplied will realize its dangerous condition, and

(c) fails to exercise reasonable care to inform them of its dangerous condition or of the facts which make it likely to be dangerous.

Comment n to Section 388 observed that

“Modern life would be intolerable unless one were permitted to rely to a certain extent on others’ doing what they normally do, particularly if it is their duty to do so.”[4]

The tension between Sections 388 and 402A did not escape the attention of the Judge John Minor Wisdom, in the landmark asbestos case, Borel v. Fibreboard Paper Products Corporation.[5] The plaintiff had characterized the case as a consumer case, with the duty to warn him as the ultimate user. The defendants had argued that the danger was obvious and that some of them had issued “cautions,” which were on shipping cartons. Judge Wisdom, in writing for the court, inferred that such cautions were aimed only at contractor-purchasers, and not the ultimate users who were owed a warning under the law:

“We agree with the Restatement: a seller may be liable to the ultimate consumer or user for failure to give adequate warnings. The seller’s warning must be reasonably calculated to reach such persons, and the presence of an intermediate party will not by itself relieve the seller of this duty.”[6]

Judge Wisdom might have just as easily agreed with Restatement 388, especially considering that plaintiff Clarence Borel and his fellow insulators were well aware of the asbestosis hazard from excessive exposure in insulation work since 1930,[7] despite Borel’s equivocal trial testimony.[8] Of course, between 1930 and 1973, when Judge Wisdom wrote, the scientific, industrial, and regulatory community had become aware of a cancer risk from asbestos exposure. Still, the courts might have been mindful that there were several different types of asbestos, and there were a multiplicity of expert opinions about the carcinogenic potential of chrysotile as opposed to amphibole asbestos fibers. Indeed, one expert in the employ of the United States government, who would go on to become a major testifying expert witness for plaintiffs in asbestos litigation, opined in a 1973 publication, that mesothelioma was a problem limited to exposure to South African crocidolite, which was not in every asbestos-containing insulation product.[9]

In any event, Judge Wisdom never directly addressed Section 388, and the framing of the Borel case as a consumer case prevailed. There was nothing inevitable about the rejection of Section 388, in the context of asbestos personal injury actions. Many other so-called toxic torts have been legally detoxified by Section 388.[10]

Some state statutes limited the coverage for workers’ compensation to diseases that manifested within a certain time window during and after employment. Such limitations logically implied that employers had no immunity to claims that arose outside the time window. Tooey v. AK Steel Corp., 623 Pa. 60, 81 A.2d 851, 864-65 (2013); see Ellen Relkin, “The Demise of the Grand Bargain: Compensation for Injured Workers in the 21st Century,” 69 Rutgers Univ. L.

Historical Malfeasance from Lawsuit Industry Expert Witnesses

July 31st, 2020

“The slickest way in the world to lie is to tell the right amount of truth at the right time-and then shut up.”

― Robert A. Heinlein, Stranger in a Strange Land

Is David Rosner’s and Gerald Markowitz’s ToxicDocs Website Really A Scholarly Enterprise?

In past posts,[1] I have called attention to a project launched by historian David K. Rosner and others to provide a free, web-based database of industry “secret” documents that come out of litigation files. Rosner and his frequent co-author, Gerald Markowitz, organized a group of sycophantic, lawsuit industry acolytes – both lawsuit industry consultants and lawyer – to write endorsements in a special issue in the Journal of Public Health Policy.[2]

The ToxicDocs project has received a warm embrace from Rosner’s fellow travellers,[3] and perhaps more disturbing, funding, to the tune of almost half a million dollars, from the National Science Foundation.[4]

The Abstract for the National Science Foundation grant is both incredibly revealing, and concealing:

“This award supports a research infrastructure project called ToxicDoc. It will enable easy access and use of millions of documents for multi-disciplinary research. Recent class-action tort litigation has unearthed millions of previously secret internal records from private firms responsible for wide-scale introduction of toxic substances, such as asbestos and polychlorinated biphenyls (PCBs). These documents include memos between executives, unpublished scientific studies, planning documents for public relations campaigns, letters to policymakers, and trade association meeting minutes.

Although technically part of the public record, this material is extremely hard to access, even for scientific researchers. ToxicDocs will provide a critical intellectual resource for scholars in multiple fields examining health, toxics, and corporate action. Expected users include scholars in environmental and health history, critical legal studies, hazards geography, environmental health and environmental justice research.

*** Without taking any particular side, ToxicDocs will provide an empirical base for informed policy debates that are grounded in key historical records.” (emphasis added)

The project is, in my view, a great deception for several reasons.

First, despite the claims of novelty, the concept is a rehash of tobacco industry documents that have been up and running on the internet for many years.[5]

Second, many if not most of the documents are, and have been, in the public domain for a long time. There are many transcripts and documents that were offered in open judicial proceedings, without any protective or confidentiality orders.

Third, the database has been sanitized to protect against disclosure of the lawsuit industry’s misdeeds. You will not find the infamous Barron & Budd memorandum, which provided instructions to asbestos plaintiffs on how to lie at depositions. You will not find the secret correspondence between plaintiffs’ lawyers and their expert witnesses about how to abridge their historical researches to avoid unfavorable revelations. You will not find any evidence of the unlawful and unethical schemes, by the lawsuit industry, to conduct mass screenings and manufacturing of claims in various mass tort litigations, including the asbestos, silica, and welding litigations.

Fourth, the database is grossly incomplete because many correlative documents that modify, qualify, or even reverse the meaning of databased documents are absent. Rosner’s database is a sham because it is deceptively imbalanced and misleading in its content. Contrary to the abstract on the National Science Foundation’s website, ToxicDocs most definitely takes a “particular side,” invariably the side of the lawsuit industry.

Let me give you some examples of omissions, relating to Gerrit W.H. Schepers, who was a participant in developing knowledge about asbestos hazards, and a frequent testifier for the lawsuit industry on general and specific causation of asbestos diseases, as well as the historical development of knowledge of those diseases.

In ToxicDocs, you will find entries for some testimony about Schepers, extolling his writings on asbestos and his role at the Trudeau Institute, at Saranac Lake, New York, usually by lawsuit industry expert witnesses, such as Barry Castleman. You will find examples of people within manufacturing industrial concerns that criticize Schepers, especially after he entered the fray as a partisan testifying expert witness for the lawsuit industry. What you will not find in ToxicDocs are many examples of Schepers’ testimony, and specifically some of his more outlandish testimony.

Schepers testified frequently. Indeed, he testified so often that he came to see himself as seemingly a “performing seal” for the lawyers who called him.[6] As a testifying expert witness, Schepers was certainly as slippery as a seal.

The first time I went off to cross-examine Dr. Gerritt Schepers was in a New Jersey case, brought by an Owens-Corning Fiberglas plantworker, who worked on making OCF’s Kaylo insulation.[7] The plantworker had undeniable asbestos exposure from which he had developed peritoneal mesothelioma. During his years of employment, Owens-Corning had used both chrysotile and amosite in manufacturing Kaylo. The amosite supplier was in South Africa and judgment proof, but the plaintiff’s lawyer was able to sue Carey-Canada, Inc., a Canadian chrysotile mining company for its supply to the factory. One other chrysotile supplier had settled, and the third, Johns-Manville was in bankruptcy. In this plantworker case, I represented Carey-Canada in what turned out to be one of its last cases in the United States, before filing for bankruptcy. After a hard fought trial, in which the plaintiff’s estate called Schepers and other expert witnesses, the Camden County jury returned a no-cause verdict on the mesothelioma claim. You will not find the trial transcript of Schepers’ testimony, whether direct or cross-examination, in ToxicDocs.

A year later, I saw Schepers again, in a New Jersey case.[8] He was again a paid expert witness, this time to testify about “state of the art,” and he was as wily as ever, in providing some wild testimony. Here is a flavor:

Q. Back in the 1950s Doctor Hueper 20 was fairly well regarded as an expert in industrial medicine?

A. No. No. No. No. He was a — he was a pathologist, epidemiologist, whose main focus was cancer, not all of the industrial medicine or hygiene, and his focus was almost singularly on the issue of relationship between industrial processes and cancer. That’s about the only way I can answer that question.

Q. All right. Was he regarded – was [sic] his opinions regarded — well regarded in the 1950s?

A. Oh, my goodness, some — some people thought that he was criminally irresponsible, and others thought he was a genius. I can’t answer that question.

Q. Did some think he was irresponsible because he rejected the association between smoking and lung cancer?

A. No. No. No. No. It is because he blamed everything, he blamed he just blamed everything as a cause. By then he got to the stage where you could get cancer from riding down the highway. You could get cancer from working with silica bricks, all things that are — you know, had been disproven, so forth.[9]

After this criminal indictment of Hueper, I chose to ratchet down the examination and ask about a less nefarious character:

Q. Let me though ask you about Doctor or Professor Philip Drinker. He was not a physician but he was an industrial hygienist.

A. No, he was an engineer.

Q. He was actually on the faculty of the Harvard School of Public Health?

A. Yes.

Q. And he was a well respected figure in industrial hygiene?

A. Yes. Yes.

Q. And, in fact, I believe that you had dedicated one of your books to him; is that correct?

A. Yes.[10]

An interesting colloquy, considering that Drinker is demonized by the ToxicDoc historians, and Drinker’s works are largely absent from the ToxicDoc database, as was my deposition transcript, and many others like it.

The Biological Action of Talc and Other Silicate Minerals

In 1973, Schepers published a written statement of his views on the carcinogenicity of talc, tremolite, chrysotile, and crocidolite.[11] Schepers’ paper, which was published in an Information Circular of the United States government, pronounced that the

“[p]roliferation of pleural mesothelium is a classical sequel to crocidolite exposure which leads to neoplasis (mesothelioma) in a high proportion of cases.”[12]

Indeed, the only suggestion of the cause of mesothelioma in this 1973 government publication by Schepers was crocidolite asbestos.[13]

A copy of Schepers’ 1973 paper is not in the ToxicDocs database.

Schepers’ Letter to Grover Wrenn

Three years later, on July 19, 1976, Schepers wrote to Grover Wrenn, who was, at the time, the Chief of the Division of Health Standards Development, in the Occupational Safety and Health Administration, within the Department of Labor, in Washington.

The subject of Schepers’ letter was “Scientific Data on Fibrous Minerals and Beryllium.” According to Schepers’ letter, he was following up on his recent meeting with Wrenn, by sending represents and copies of articles on asbestos and beryllium, which were under intense scrutiny from OSHA at the time.

In his letter to Wrenn, Schepers summarized his views at the time:

“As you can see, my researches cast considerable doubt on the proposition that [A]merican fibrous minerals are carcinogenic. I am not one of those who doubt the carcinogenicity of everything. To the contrary, I believe I have helped prove that some environmental pollutants are carcinogenic. For this reason, you may perhaps accept the credibility of my findings when I state that I could detect no evidence of carcinogenicity for either chrysotile, talc or fiberglass.”

Schepers’ letter to Grover Wrenn is not in ToxicDocs.

Schepers’ Letter to Navy Captain D. F. Hoeffler

By 1978, the Navy was up to its gunnels in asbestos claims, and Schepers sensed an opportunity. On March 10, 1978, Schepers wrote to Captain D.F. Hoeffler, who with the Medical Corps in the Bureau of Medicine and Surgery, in the Department of the Navy. His intent was clear; he was looking for consulting work in connection with lawsuits. His letter was a remarkable snap shot of what an ostensible expert on asbestos was thinking and writing about fiber type and cancer in 1978, and so I am reproducing the letter in full:

Dear Captain Hoeffler:

A multitude of duties and interruptions delayed my response to your telephone inquiry of a few weeks ago. You desired some details concerning my experience with the pneumoconioses. I had to dig through some boxes to get you this material and some we had to Xerox afresh.

Here is a CV and some reprints which will possibly be helpful. Since I have been involved with so many things my expertise with respect to asbestosis is somewhat hidden among the rest. For emphasis therefore let me summarize that my clinical and research involvement with asbestosis and thus also lung cancer spans some thirty years. I commenced this work in South Africa, where as a pulmonary medical director for the pneumoconiosis Bureau we researched the working conditions and health of all employee of that countries[sic] extensive crocidolite and amosite mines an industries. The fact that mesotheliomatosis can be associated with exposure was first discovered by me during 1949 at the Penge-Egnep mines in the Eastern Transvaal. It is also important to know that only one out of three persons who develop mesothelioma ever was exposed to asbestos dust. The Institute for Pneumoconiosis Research which I started there has abundant evidence about this.

In the USA I next studied the asbestos problem for the Quebec Government and the Johns Manville Company and also for various asbestos producing companies. This embraced research on human subjects, lung tissue and experimental animals. The net result of my fifteen years of work in this field here has been to convince me that chrysotile, which is the North American type of asbestos, is relatively innocuous as compared to the African and Russian varieties. I have never seen a case of lung cancer develop in any person exposed to chrysotile only. However I have seen plenty of lung cancers in asbestos workers. This is because most asbestos workers also are exposed to carcinogenic materials other than asbestos and all the cases with lung cancer also were chronic lung self-mutilators through cigarette smoking. In a rather major set of experiments of mine I exposed animals to the most potent known carcinogen (beryllium sulphate) and then exposed them to asbestos (chrysotile) dust. These animals had fewer cancers than those exposed to the beryllium sulphate. So chrysotile is not even a significant co-carcinogen. I reversed the order of the exposure, namely asbestos (chrysotile) first and then the BeSO₄. The result was the same. The animals exposed only to chrysotile never developed any lung cancers.

I probably have the largest collection of asbestosis case materials, having been a consultant to hundreds of physicians. I have a very detailed knowledge of what various types of asbestos can an cannot do to the lungs. If my command of this subject can be of any cse [sic] to the Navy in the current law suit please feel to use my services as you deem fit.

Other reprints will be forwarded in separate packages as I locate them. I am still extricating myself from my recent move.

Sincerely,

Gerrit W. H. Schepers, MD, Sc.D.

Aside from implicating smoking as the overwhelming, most important cause of lung cancer, Schepers exculpated chrysotile (the North American asbestos fiber) from causing cancer. At the same time, he pointed the finger to asbestos mined in the Transvaal, which was mostly amosite but with some crocidolite, as the cause of mesothelioma.[14] Indeed, the Transvaal was the source of almost all of world’s supply of amosite and much of its crocidolite. Schepers dates his “discovery” to 1949, a full decade and some before the date typically given for the discovery by Christopher Wagner.[15] A search of Schepers’ publications fails to show that he ever published his “discovery,” even after he came to the United States in the early 1950s. At the time, American companies were importing considerable South African amphibole asbestos, which was used a wide variety of products, including asbestos-containing insulation.

A disinterested historian might have that this letter should have been included in a database of historical documents about who knew what and when, but…

Schepers’ Letter to Captain D. F. Hoeffler is not in ToxicDocs.

This exercise about Schepers could and should be repeated on any number of other topics and writers. It is hard to escape the conclusion that ToxicDocs is not a true research historical archive. It is designed by, and for, historians who advocate for the lawsuit industry. As such, the database frames the issues of historical knowledge as manufacturing industry versus individuals, without a meaningful exploration of what labor unions and the government knew and did when they had control over exposures to various chemicals, dusts, and materials.

What a waste of taxpayers’ money!

Big Blue versus Asbestos Fiber Type Egalitarianism

July 16th, 2020

The differential potency for causing mesothelioma among asbestos varieties is well established. In the year 2000, John Hodgson of the Epidemiology and Medical Statistics Unit, in the British Health and Safety Executive, published an analysis of the relative potency for different asbestos minerals. The published analysis showed that the estimated ratio of excess mesothelioma mortality for the same exposure in fiber/milliliter – years was 1:100:500 for chrysotile, amosite and crocidolite, respectively.[1] The analysis was recently updated by David Garabrant, who charitably considered some mixed exposure cohorts as chrysotile only,[2] with the result of slightly less extreme relative risks for amosite and crocidolite.[3]

The lawsuit industry’s expert witnesses have long been afraid to acknowledge the differential potency of chrysotile (with or without tremolite contamination) and the commercial amphibole fibers, amosite and crocidolite.[4] Why? First, by lumping the fiber types together, they obtain risk ratios for mesothelioma for all workers, regardless of the nature of their specific exposures. Their quest to seek compensation and obtain bans of all asbestos works better by simplification and exaggeration of risk. Second, they knew in the early days of the asbestos litigation in the United States that the South African amphibole suppliers were beyond the reach of courts and litigants in American courts. They were alert to the litigation risk that the Canadian mining companies would escape liability because the overwhelming bulk of the risk derived from South African amphibole fiber. Later cases involved chrysotile-only products that did not cause the level of exposures seen from friable insulation and cloth materials. A differential in risk for low-exposure chrysotile products raised serious questions whether such products could contribute substantially to a given case of mesothelioma, for which there was also exposure to amosite and crocidolite. Interestingly, some companies, concerned about losing contribution from low-exposure chrysotile products, took similar positions. Third, the exaggerated risks of all fibers helps advance their “each and every fiber” (or cumulative) causation theory, which they invoke to claim that even fleeting exposures from asbestos-containing products are “substantial contributing factors.” Consider how that argument goes when one product is akin to drinking 750 ml. of whiskey, and another is the equivalent of 1.5 ml. A man drinks a fifth of whiskey at one bar, and a thimble full of whiskey at the second. Most juries can see that the thimble was not substantial factor in contributing to the man’s drunkenness. Still, if you were the company that sold the whole bottle, you would love to have the thimble seller pay a 50% share; no? If you were the drunkard, and the seller of the bottle of whiskey was now a “bankruptcy trust,” obtaining a pro-rate share against the thimble seller would be lovely.

The extent to which crocidolite asbestos contributed to the horrific burden of mesothelioma was muddled by the writings of Irving John Selikoff. Before Selikoff wrote anything about any asbestos type and cancer, in 1960, in a remarkable case series, Christopher Wagner and colleagues showed a strong relationship between mesothelioma and crocidolite (blue) asbestos. Selikoff may not have had any first-hand knowledge of the unique potency of “big blue,” but he had been a regular testifier in workman’s compensation cases for UNARCO (Union Asbestos & Rubber Company) workers throughout the 1950s.[5]

In a 1965 volume, which Selikoff edited, of proceedings of a 1965 conference, which which Selikoff chaired, Selikoff presented United States Department of Commerce statistics that showed for six years reported (1957-1962), crocidolite imports exceeded amosite imports.[6] In that same year, 1965, in a prominent article in the New England Journal of Medicine, Selikoff played down the role in causing mesotheliomas in the United States.[7]

“Crocidolite is a relative newcomer to the American asbestos-industry scheme. Thus, American imports of crocidolite (none is mined here) were less than 500 tons in 1935 and had reached a level of only 20,000 tons even in 1962. In contrast, chrysotile, the type of asbestos fiber widely used in the American asbestos industry, was imported at a level of 165,000 tons in 1935 and 650,000 tons in 1962.⁵”

Selikoff thus chose to paint the mesothelioma problem as a dichotomy between blue asbestos and chrysotile, while leaving amosite out of the analysis completely. Indeed, the word “amosite” (or the word grunerite) does not appear in the New England Journal of Medicine article .

Aside from misleadingly framing the South Africa experience as limited to blue asbestos, and the United States experience as somehow limited to chrysotile, Selikoff presented the import statistics for amosite and crocidolite in a rather confusing way. In 1972, Selikoff presented a more revealing set of statistics about amphibole fiber imports, in the context of discussing whether amosite was carcinogenic (despite testifying in the UNARCO cases two decades earlier):

“Few data exist concerning the comparative neoplastic potential of the several kinds of asbestos in man. Some information is available for chrysotile,⁴ crocidolite,⁵ and anthophyllite.⁶ However, there has been no evidence to indicate whether or not the amosite variety is also carcinogenic.”[8]

Selikoff went on, in this 1972 article, to present more complete data on fiber type consumption in the United States, although still only estimates:

The 1972 article raises interesting questions about Selikoff’s own testimony in the 1950s New Jersey workman’s compensation cases on behalf of UNARCO workers. Table 1, reproduced above from Selikoff’s 1972 article, also throws considerable doubt upon generalizations about what fiber types were commercially used by insulators and others throughout the 20^th century, in the United States. We can see that for 1920 and 1925, there is an “other” category, which could be virtually anything, and no data about South African fibers, which could mean none or it could mean simply no data available. In 1930, 1935, and 1940, there are data for crocidolite and amosite combined. Throughout the 1930s, the “other” category grew considerably, introducing serious ambiguity and doubt into Selikoff’s argument. Selikoff’s 1965 article in the New England Journal of Medicine gave a distorted view of the supply issue, but to my knowledge, it has never been corrected.

From Table 1, above, we see crocidolite and amosite data segregated for the first time in 1945. And for that year, the supply of crocidolite (8,700 tons) was almost twice that of amosite (4,500 tons). There was certainly no warrant for claiming that insulators and American factory workers had no amosite or crocidolite exposure before and after World War II.

While these confusions were being put forward, other countries were acting to control the occupational hazards of asbestos by differentially banning crocidolite, and imposing stricter controls on chrysotile. Selikoff led the United States in a different direction. The photograph and text below is from the May 1966 issue of the Port of Houston Magazine, showing how blue asbestos was continuing to invade the United States, while Selikoff and many of his colleagues were pointing to chrysotile.

Port of Houston Magazine 21 (May 1966)

In a 1968 conference presentation, with the benefit of hindsight, Selikoff addressed the issue of the forseeability of widespread asbestos disease:

“At the outset of this presentation, I questioned whether asbestos might properly be included as an unanticipated environmental hazard. Yet the less iconoclastic among us might have countered with: it must have been-we could not have knowingly allowed this to come to pass! Surely the explanation lies in the length of the period that elapses between exposure and disease which kept us from really knowing the problem until now.

Perhaps so. Indeed, I do not share the demonological theory of industrial hygiene history, in which industry is seen as callously exchanging human disease for profits. Rather, I would say industry shared the ignorance and lethargy of us all. The answer will come in these next several years. We have some reason for optimism. First, we have the law of averages on our side-sooner or later, some important environmental hazard is bound to be controlled. I suspect asbestos will be one. We have reason to believe that the dose-disease relationship is on our side-to the present, disease has been uncommon except with significant exposure. And our data suggest further that such significant exposure can be prevented, that we can learn to live and work with asbestos. All it will take is the doing -but herein lies another tale.”[9]

Selikoff’s position was especially generous to manufacturers who had used crocidolite after 1960, when Wagner alerted the community to para-occupational mesothelioma cases from blue asbestos exposure. Selikoff’s dismissal of the problem of blue asbestos as somehow a problem of English workers allowed the reality of blue asbestos use to be ignored, and then hidden with the myth of equal potency among all asbestos types. Twenty years after Selikoff’s New England Journal of Medicine article, no less an authority than Dr. Harriet Hardy would refer to mesothelioma as

“A fatal malignancy [mesothelioma] associated with inhalation of a single form (crocidolite) of asbestos invaded the chest wall (pleura) and/or the abdominal wall.”[10]

It is time to acknowledge the harm caused by asbestos fiber type egalitarianism.

More Rosner & Markowitz Faux History of Workplace Safety

July 9th, 2020

Historians, often of the subspecies social, labor, or Marxist, have frequently been recruited by the lawsuit industry to support their litigation efforts. One such historian, David Rosner, sometimes with his friend Gerald Markowitz, seems to show up everywhere, including the infamous Ingham case, in which he served largely as a compurgator and moralist.

Given the role that such historians are permitted to play in high-stakes litigation, it is important to look at their more professional work in the journals for insights into their methodology. A couple of years ago, David Rosner and Gerald Markowitz, published a story about governmental regulation of workplace safety before the passage of the Occupational Health and Safety Act in 1970.[1] Their article is an interesting case study of how to bias an historical analysis by leaving out material facts, a modus operandi in their litigation work as well.

The abstract gives a brief flavor of their tendentious narrative:

“The Occupational Safety and Health Act of 1970 and the Workers Right to Know laws later in that decade were signature moments in the history of occupational safety and health. We have examined how and why industry leaders came to accept that it was the obligation of business to provide information about the dangers to health of the materials that workers encountered. Informing workers about the hazards of the job had plagued labor–management relations and fed labor disputes, strikes, and even pitched battles during the turn of the century decades. Industry’s rhetorical embrace of the responsibility to inform was part of its argument that government regulation of the workplace was not necessary because private corporations were doing it.”

The authors attempt to tell a one-sided story that only “voluntary” warnings were assumed by employers before OSHA, without the force of law. The enterprise perpetuates a common myth of plaintiffs’ advocates that pre-OSHA occupational safety was based upon employers’ voluntary assumption of responsibility, and that it was not until the passage of the OSH Act that employers were subject to legal obligations to warn.

In terms of scholarship, Rosner and Markowitz break no new ground; indeed, the topic was presented with more historical acumen by scientists in an article that predated the Rosner and Markowitz article by a decade.[2] More damning, however, the historians laureate of the plaintiffs’ bar contradict their thesis that manufacturers had only voluntary commitments to their worker safety by pointing to the law of the 1930s, which placed a common law duty of care on employers:

“As one judge in the New Jersey Supreme Court opined at the time, ‘It was the duty of the defendant company to exercise reasonable care that the place in which it set the deceased at work . . . should be reasonably safe for the plaintiff, and free from latent dangers known to the defendant company, or discoverable by an ordinary prudent master, under the circumstances’.”[3]

Of course, legal historians are well aware that there has been a common law duty of reasonable care owed by “masters” (employers) to their “servants” (employees), including a duty to protect them from occupational hazards such as overexposure to dusts, including respirable crystalline silica.[4] There was nothing voluntary about the common law duty.

What makes Rosner and Markowitz’s account egregiously wrong is its complete omission of the extensive state governmental regulation of occupational exposures in advance of OSHA. Taking New York (where Rosner and Markowitz live and teach) as an example, we can see that the state had occupied the field of regulating workplace safety many decades before the enactment of OSHA.

The industrial use of crystalline silica provides an example of a “hot” issue in early 20^th century industrial hygiene. Initial efforts in New York state, starting as early as 1913, focused on the most prevalent industrial exposures, such as foundries, where whole grain and ground silica was used in metal casting and cleaning. New York’s long-recognized common law duty of employers to provide a safe workplace was statutorily codified in 1921.[5] By 1935, silicosis became a compensable disease under New York law, in all industrial settings.

New York’s efforts to protect industrial workers from silica exposure achieved national recognition in 1940, when LIFE magazine published a description of measures taken by the state to safeguard workers on an 85-mile tunnel aqueduct project. The project required thousands of workers to drill through quartzite rock (composed of almost entirely of crystalline silica). Intent on avoiding a repeat of the Hawk’s Nest tragedy, the state imposed safety measures on the project, including wet drilling, elaborate ventilation, and air sampling. LIFE declared the New York state precautions to be “[a] triumph of preventative medicine.”[6]

New York courts also have been in the forefront of recognizing the hazards of silica exposure, and addressing the legal implications of knowledge of those hazards. In 1944, New York’s highest court, the Court of Appeals, held, in a silicosis personal injury case, that:

“[i]t is a matter of common knowledge that it is injurious to the lungs and dangerous to health to work in silica dust, a fact which defendant was bound to know.”[7]

From the 1950s on, New York comprehensively regulated the use of crystalline silica in the industrial workplace. In 1956, New York promulgated “Industrial Code Rule No. 12 – Control of Air Contaminants,” which governed “all processes and operations releasing or disseminating air contaminants in any workroom or work space” (§ 12.1), and clearly defined the employer’s duties to protect workers, regardless of the industry sector or manufacturing process.

Silica was specifically covered by these 1956 regulations. Section 12.2 of the Rule, “Responsibility of employers,” requires:

“Every employer shall observe and effect compliance with the provisions of this rule relating to prevention of air contamination and to providing, installing, operating and maintaining control or protective equipment, and shall instruct his employees as to the hazards of their work, the use of such control or protective equipment and their responsibility for complying with this rule.”

Section 12.25 specifically identified industrial processes that create “air contaminants,” such as free silica.

New York law imposed correlative obligations upon workers. Under § 12.3, the employee’s responsibility was to use the controls and equipment provided by his employer for his protection.

New York’s 1956 regulations, like the federal regulations that would follow in the early 1970s, focused on avoiding exposure to hazardous substances such as crystalline silica in the first instance. Section 12.7, “Prevention,” requires that

“[a]ll processes and operations where practicable shall be so conducted or controlled as to prevent avoidable creation of air contaminants.”

Section 12.9, General control methods, specifies “[o]ne or more of the following methods . . . control dangerous air contaminants:

Substitution of a material which does not produce air contaminants;
Local exhaust ventilation at the source of generation of the air contaminant;
Dilution ventilation in any work space in which air contaminants are generated or released;
Application of water or other wetting agent to prevent air contaminants;
Other methods approved by the board.”

Section 12-29, “Maximum allowable concentrations – evidence of dangerous air contaminants,” provides that air contaminants in quantities greater than those listed “shall constitute prima-facie evidence that such contaminants are dangerous air contaminants.” In a chart entitled “Mineral Dusts,” the 1956 regulations specifically imposed a maximum exposure for free crystalline silica, depending upon the percentage concentration of silica in the total dust.

In 1958, New York revised Rule 12, with its extensive regulation of silica, to provide an even more detailed description of employer responsibilities of employers for air monitoring, ventilation, respiratory programs, and worker education. Section 12.6 of the 1958 Regulations, “Prevention of air contamination,” mandated that

“[a]ll operations producing air contaminants shall be so conducted that the generation, release or dissemination of air contaminants is kept at the lowest practicable level.”

Rule 12 was revised again in 1963, and in 1971, each time with greater specificity of the employer’s responsibility for safe handling of air contaminants, which was always defined to include silica dust. These state regulations never restricted their application to any particular industry. Crystalline silica was thus regulated in every industry conducted within New York.

New York state recruited and employed some of the leading scientists in the field of industrial hygiene and occupational medicine to serve in its Department of Labor’s Division of Industrial Hygiene. Leonard Greenberg, who was a graduate of Columbia College of Engineering, and who received his Ph.D. and M.D. degrees from Yale, served as the executive director of the New York State Division of Industrial Hygiene 1935 to 1952. He later served as an official on pollution control until 1969.[8] While at the New York Department of Labor, contributed widely to scientific publications on occupational health,[9] as did many other scientists under his supervision.[10]

Omission of material facts seems to be a key aspect of the faux historian’s methodology, and very useful in litigation if your conscience permits it.

Professors Rosner and Markowitz, labor historians, or historians laboring in courtrooms, have made a second career out of testifying about other people’s motivations. Consider their pronouncement:

“In the postwar era, professionals, industry, government, and a conservative labor movement tried to bury silicosis as an issue.”

David Rosner & Gerald Markowitz, Deadly Dust: Silicosis and the Politics of Occupational Disease in the Twentieth Century America 213 (Princeton 1991); Gerald Markowitz & David Rosner, “Why Is Silicosis So Important?” Chap. 1, at 27, in Paul-André Rosental, ed., Silicosis: A World History (2017). Their accusation is remarkable for any number of reasons,¹ but the most remarkable is that their claim is unverified, but readily falsified.²

Previously, I have pointed to searches in Google’s Ngram Book viewer as well as in the National Library of Medicine’s database (PubMed) on silicosis. The PubMed website has now started to provide a csv file, with articles counts by year, which can be opened in programs such as LibreOffice Calc, Excel, etc, and then used to generate charts of the publication counts over time.

Here is a chart generated form a simple search on <silicosis> in PubMed, with years aggregated over roughly 11 year intervals:

The chart shows that the “professionals,” presumably physicians and scientists were most busy publishing on, not burying, the silicosis issue exactly when Rosner and Markowitz claimed them to be actively suppressing. Many of the included publications grew out of industry, labor, and government interests and concerns. In their book and in their courtroom performances,, Rosner and Markowitz provide mostly innuendo without evidence, but their claim is falsifiable and false.

To be sure, the low count in the 1940s may well result from the relatively fewer journals included in the PubMed database, as well as the growth in the number of biomedical journals after the 1940s. The Post-War era certainly presented distractions in the form of other issues, including the development of antibiotics, chemotherapies for tuberculosis, the spread of poliomyelitis and the development of vaccines for this and other viral diseases, radiation exposure and illnesses, tobacco-related cancers, and other chronic diseases. Given the exponential expansion in scope of public health, the continued interest in silicosis after World War II, documented in the PubMed statistics, is remarkable for its intensity, pace Rosner and Markowitz.

1 “Conspiracy Theories: Historians, In and Out of Court” (April 17, 2013). Not the least of the reasons the group calumny is pertinent is the extent to which it keeps the authors gainfully employed as expert witnesses in litigation.

David Rosner’s Document Repository

July 23rd, 2017

David Rosner and Gerald Markowitz are leftist labor and social historians in Columbia University and City University of New York, respectively. Both are frequently disclosed by plaintiffs’ counsel as expert witnesses on historical issues, and both often testify at asbestos and other personal injury trials¹. Markowitz has been excluded in at least one reliability challenge².

The two historians, who appear so often together on plaintiffs’ designations that they are sometime referred to as a unified persona, Rosnowitz, have create a website, “Project Toxicdocs,” supposedly in an alpha version³.

The Toxic Docs website does not identify Rosner and Markowitz by name as authors or sponsors, but the website’s content and goals bear their indelible stamp, as well as the concordance of their institutional affiliations of Columbia and CUNY. The website promises “[b]lazingly fast” searches and access to previously confidential, classified industry documents on “industrial poisons”:

“This dataset and website contain millions of pages of previously secret documents about toxic substances. They include secret internal memoranda, emails, slides, board minutes, unpublished scientific studies, and expert witness reports — among other kinds of documents — that emerged in recent toxic tort litigation.

Over the next couple years, we’ll be constantly adding material from lawsuits involving lead, asbestos, silica, and PCBs, among other dangerous substances. Innovations in parallel and cloud computing have made conversion of these documents into machine-readable, searchable text a far faster process than would have been the case just a decade ago.”

Similar efforts have been put into place for documents collected in tobacco and other litigations⁴. David Egilman, another regular testifier for the Lawsuit Industry once maintained a website with a large library of documents he relied upon for his ethics and state-of-the-art opinion testimony in various litigations.

A trial run through the “dataset” for the search term “silicosis” turned up 44 documents, most of which had nothing to do with silica or silicosis, and many of which were duplicates. Remarkably, there were no documents from government or labor unions.

We are sure that these historian expert witnesses will improve their efforts to be comprehensive and balanced, with practice.

Ancient Truths

May 5th, 2016

David Sackett, in some paternity disputes called the “father of evidence-based medicine,” supposedly once claimed that:

“Half of what you’ll learn in medical school will be shown to be either dead wrong or out of date within five years of your graduation; the trouble is that nobody can tell you which half–so the most important thing to learn is how to learn on your own.”

See Ivan Oransky, “So how often does medical consensus turn out to be wrong?” Retraction Watch (July 11, 2011). Sackett’s meta-statement was itself certainly not “evidence based,” but his point is well taken. Time ultimately erodes the authority of the truthiest sounding claims to medical knowledge. Sara Teichholtz, “The Differential: Half of What You’re Learning is Wrong,” (Dec. 14, 2013). Only lawyers and theologians would think that a statement in an old document or text, once authenticated, has some claim on us as the “truth.”

The Federal Rules of Evidence provide an exception to the rule against hearsay for statements made in ancient documents, those at least twenty years old. Rule 803(16). In 2015, the Judicial Conference’s Committee on Rules of Practice and Procedure proposed retiring the ancient document hearsay rule.[1] The exception created for documents authenticated as “ancient” (> 20 years old) is so inimical to the truth-finding function of trials, that courts strain to avoid finding the documents “authenticated.” See, e.g., Kalamazoo River Study Group v. Menasha Corp., 228 F.3d 648 (6th Cir. 2000).

The proposal to abolish this dangerous exception to the rule against hearsay has engendered resistance from some quarters over its ability to eliminate otherwise admissible evidence in cases involving long-past events, such as environmental or occupational disease litigation. The resistance, however, is misguided. The Committee’s proposal would not affect the authenticity presumption of an “ancient document,” and such documents could still be used to show state of mind, intention, motive, or notice. If the asserted statement in the old document is actually true, then there is likely much more recent, robust evidence to support the statement. The rule as it now stands is capable of a great deal of mischief. The fact that a document has survived intact in a place where one would expect to find it may add to its presumptive authenticity, but in many technical, scientific, and medical contexts, the “ancient” provenance actually makes the content likely to be false. Technical and scientific facts and opinions have changed too quickly to endorse statements simply because of they were written down somewhere, over 20 years ago. See “Time to Retire Ancient Documents As Hearsay Exception” (Aug. 23, 2015).

Although many in the legal academy have voiced opposition to the proposal[2], one law professor, Daniel Capra, has astutely observed that we will soon have a flood of easily authenticated documents of doubtful veracity, called websites, and other electronic documents, which have reached the age of evidentiary majority. Daniel J. Capra, “Electronically Stored Information and the Ancient Documents Exception to the Hearsay Rule: Fix It Before People Find Out About It,” 17 Yale J.L. & Tech 1 (2015). The truth of a proposition requires more than the lapse of 20 years since some nincompoop wrote it down.

Ramazzini Serves Courtroom Silica Science Al Dente

July 25th, 2015

Collegium Ramazzini styles itself as an “independent, international academy.” The Collegium Ramazzini was founded in 1982, by the late Irving Selikoff and others to serve as an advocacy forum for their pro-compensation and aggressive regulation views on social and political issues involving occupational and environmental health.

The Collegium is a friendly place where plaintiffs’ expert witnesses, consultants, and advocates never have to declare their conflicts of interest.[1] Last year, in October 2014, the Collegium conducted a conference on silica health issues, entitled “Silica Three Hundred Years Later: Occupational Exposure, Medical Monitoring, and Regulation.”

The silica session was chaired by Christine Oliver, one of plaintiff’s key expert witnesses in Allen v. Martin Surfacing, 263 F.R.D. 47 (D. Mass. 2009). See “Bad Gatekeeping or Missed Opportunity – Allen v. Martin Surfacing” (Nov. 30, 2012). The purported goal of the session was

“to shine a light on silica as a persistent and dangerous threat to the health of exposed workers worldwide,” focusing on the following issues:

“1) Occupational silica exposures, new and old;

2) silica as a recognized human lung carcinogen and its interaction with other lung carcinogens such as tobacco smoke;

3) the role of silica and silicosis in tuberculosis;

4) issues relevant to medical surveillance of silica-exposed workers as set forth in OSHA’s proposed silica standard;

5) the role of the US Government in protecting the health of silica-exposed workers; and

6) international variability in addressing the threat to worker health posed by silicosis.”

Recently, the Collegium updated its website to provide PDF files of some of the conference presentations:

Carol H. Rice, “Silica – old, new and emerging uses result in worker exposure”

Arthur L. Frank, “Silica as a lung carcinogen”

Rodney Ehrlich, “Silica in the head of the snake. Silica, gold mining, and tuberculosis in southern Africa”

Christine Oliver, “Medical surveillance for silica-related disease: the Collegium responds to OSHA’s proposed rulemaking,”

Gregory R. Wagner, “US Government role in recognizing, reducing, and regulating silica risk: 80 years and counting”

Sverre Langard, “Silicosis 300 years after Ramazzini: Eradication in some countries, increased incidence in others”

A poster session chaired by Melissa McDiarmid and Carol Rice, revealingly titled “Sustainable Work 2020 – an advocacy platform for Horizon 2020,” followed. Casey Bartrem asked whether “Asbestos-induced lung cancer in Germany: is the compensation practice in accordance with the epidemiological findings?” Odds are that this presentation was a brief for greater compensation. Xaver Baur of Germany, presented on the “Ethics in the applied sciences: The challenge of preventing corporate influence over public health regulation,” but remarkably no one presented on the challenge of preventing the litigation and compensation industry’s influence over public health regulation.

You won’t find any cutting-edge science in the linked slides, but you will find some interesting revelations. Sverre Langard’s presentation makes the dramatic point that silicosis has been declining, despite the hand waving of OSHA Administrator David Michaels, and the histortions of Rosner and Markowitz. Consider Langard’s slide, based upon CDC data:

And consider the admissions of Arthur Frank, veteran plaintiffs’ expert witness, who acknowledged that:

“until very recently it [silica] was not recognized as a carcinogen.”

True to form, Dr. Frank blamed Selikoff and his other teachers at Mt. Sinai Hospital in New York City, where he trained:

“At Mount Sinai I did not get trained that silica was a carcinogen”

Well, even a scurry of blind squirrels sometimes find their nuts!

The Unreasonable Success of Asbestos Litigation

July 25th, 2015

In asbestos litigation, the plaintiffs’ bar has apparently invented a perpetual motion machine that feeds on outrage that will never run out. Still, lawyers who have not filled their wallets with legal fees from asbestos cases sometimes attempt to replicate the machine. For the most part, the imitators have failed.

What accounts for the unreasonable success of asbestos litigation? Unlike pharmaceutical litigation, exposure does not require a prescription. Although asbestos insulators and applicators experienced the most exposure, other trades and occupations worked with, or near, asbestos materials. Anecdotal testimony of exposure suffices in almost every case. Add para-occupational exposure, and the sky’s the limit for the class of potential plaintiffs. See Lester Brickman, “Fraud and Abuse in Mesothelioma Litigation,” 88 Tulane L. Rev. 1071 (2014); Peggy Ableman, “The Garlock Decision Should be Required Reading for All Trial Court Judges in Asbestos Cases,” 37 Am. J. Trial Advocacy 479, 488 (2014).

Then there is the range of diseases and disorders attributable to asbestos. Excessive exposure to asbestos minerals cause non-malignant pleural plaques and thickening, as well as lung fibrosis, asbestosis. Some asbestos minerals cause mesothelioma, and despite a differential in potency among some of the minerals (between amosite and crocidolite), the general and specific causation of mesothelioma is often uncontested. Furthermore, lung cancer in the presence of asbestosis may be the result of interaction of asbestos exposure and cigarette smoking. Plaintiffs’ counsel and The Lobby have expanded the list of attributable diseases to include non-pulmonary cancers, only to find some defendants willing to pay money on these claims as well.

In addition to the ease of claiming, or manufacturing, exposure, and the willing cooperation of the occupational medical community in supporting medical causation, asbestos litigation is a lightning rod for moral outrage in the courtroom. Plaintiffs claim that “industry” knew about the hazards of asbestos, including its carcinogenicity, long before warnings appeared. Defending the knowledge claim requires nuanced explanation of shifting standards for establishing causality as epidemiology developed and was applied to putative asbestos-related cancer outcomes, as well as changing views about the latencies of asbestos-related diseases.

Every once in a while, plaintiffs’ and defense counsel[1], the media[2], the academy[3], and the insurance industry[4] ask whether “silica” is the next asbestos. Although the prospects have been, and remain, dim, plaintiffs’ counsel continue to try to build their litigation palace on sand, with predictably poor results. See Kimberley A. Strassel, “He Fought the Tort Bar — and Won,” Wall St. J. (May 4, 2009).

There are many serious disanalogies between asbestos and silica litigation. One glaring difference is the inability to summon any outrage over suppressed or nondisclosed knowledge of alleged silica cancer hazards. The silica cancer state of the art, written by those who are lionized in the asbestos litigation – Hueper, Schepers, and Hardy, along with NIOSH and the Surgeon General, all appropriately denied or doubted silica as a cause of lung cancer. See below. When the IARC shifted its views in the 1990s, under the weight of determined advocacy from some partisans in the occupational medicine community, and with the help from some rather biased reviews, industry promptly warned regardless of the lack of scientific support for the IARC’s conclusion. The manufacturing of faux consensus and certainty on silica and lung cancer is an important counter to the incessant media stories about the manufacturing of doubt on topics such as climate change.
