History of Silicosis Litigation

January 31st, 2019

“Now, Silicosis, you’re a dirty robber and a thief;
Yes, silicosis, you’re a dirty robber and a thief;
Robbed me of my right to live,
and all you brought poor me is grief.
I was there diggin’ that tunnel for just six bits a day;
I was diggin’ that tunnel for just six bits a day;
Didn’t know I was diggin’ my own grave,
Silicosis was eatin’ my lungs away.”

Josh White, “Silicosis Is Killin’ Me (Silicosis Blues)” (1936)

Recently, David Rosner, labor historian, social justice warrior, and expert witness for the litigation industry, gave the Fielding H. Garrison Lecture, in which he argued for the importance of the work that he and his comrade-in-arms, Gerald Markowitz, have done as historian expert witnesses in tort cases.1 Although I am of course grateful for the shout out that Professor Rosner gives me,2 I am still obligated to call him on the short-comings of his account of silicosis litigation.3 Under the rubric of “the contentious struggle to define disease,” Rosner presents a tendentious account of silicosis litigation, which is highly misleading, for what it says, and in particular, for it omits.

For Rosner’s self-congratulatory view of his own role in silicosis litigation to make sense, we must imagine a counterfactual world that is the center piece of his historical narrative in which silicosis remains the scourge of the American worker, and manufacturing industry is engaged in a perpetual cover up.

Rosner’s fabulistic account of silicosis litigation and his role in it falls apart under even mild scrutiny. The hazards of silica exposure were known to Josh White and the entire country in 1936. Some silicosis litigation arose in the 1930s against employers, but plaintiffs were clearly hampered by tort doctrines of assumption of risk, contributory negligence, the fellow-servant rule. To my knowledge, there were no litigation claims against remote suppliers of silica before the late 1970s, when courts started to experiment with hyperstrict liability rules.

Eventually, the litigation industry, buoyed by its successes against asbestos-product manufacturers turned their attention to silica sand suppliers to foundries and other industrial users. Liability claims against remote suppliers of a natural raw material such as silica sand, however, made no sense in terms of the rationales of tort law. There was no disparity of information between customer and supplier; the customer, plaintiffs’ employer was not only the cheapest and most efficient cost and risk avoider, the employer was the only party that could control the risk. Workers and their unions were well aware of the hazards of working in uncontrolled silica-laden workplaces.

Although employer compliance with safety and health regulations for silica exposure has never been perfect, the problem of rampant acute silicosis, such as what afflicted the tunnel workers memorialized by Josh White, is a thing of the past in the United States. The control of silica exposures and the elimination of silicosis are rightly claimed to be one of the great public health achievements of the 20th century. See Centers Disease Control, “Ten Great Public Health Achievements — United States, 1900-1999,” 48 Morbidity & Mortality Weekly Report 241 (April 02, 1999).

Interestingly, after World War II, silicosis has been a much greater problem in the communist countries, such as China, the countries that made up the Soviet Union. Rosner and Markowitz, however, like the leftist intellectuals of the 1950s who could not bring themselves to criticize Stalin, seem blind to the sorry state of workplace safety in communist countries. Their blindness vitiates their historical project, which attempts to reduce occupational diseases and other workplace hazards to the excesses of corporate capitalism. A fair comparison with non-capitalist systems would reveal that silicosis results from many motives and conditions, including inattention, apathy, carelessness, concern with productivity, party goals, and labor-management rivalries. In the case of silicosis, ignorance of the hazards of silica is the least likely explanation for silicosis cases arising out of workplace exposures after the mid-1930s.

In the United States, silicosis litigation has been infused with fraud and deception, not by the defendants, but by the litigation industry that creates lawsuits. Absent from Rosner’s historical narratives is any mention of the frauds that have led to dismissals of thousands of cases, and the professional defrocking of any number of physician witnesses.  In re Silica Products Liab. Litig., MDL No. 1553, 398 F.Supp. 2d 563 (S.D.Tex. 2005).

Nor does Rosner deign to discuss the ethical and legal breaches committed by the plaintiffs’ counsel in conducting radiographic screenings of workers, in the hopes of creating lawsuits. With the help of unscrupulous physicians, these screenings were unnaturally successful not only in detecting silicosis that did not exist, but in some cases, in transmuting real asbestosis into silicosis.4

Many silicosis cases in recent times were accompanied by more subtle frauds, which turned on the “failure-to-warn” rhetoric implicit in the Restatement (Second) of Torts § 402A. Consider the outbreak of silicosis litigation in western Pennsylvania, in the mid-1980s. Many of the men who claimed to have silicosis had significant silica exposure at the Bethlehem and U.S. Steel foundries in the Johnstown areas. Some of the claimants actually had simple silicosis, although discovery of these claimants’ workplace records revealed that they had been non-compliant with workplace safety rules.

The Johnstown, Cambria County, cases were not the result of unlawful medical screenings, paid for by plaintiffs’ lawyers and conducted by physicians of dubious integrity and medical acumen. Instead, the plaintiffs’ lawyers found their claimants as a result of the claimants’ having had previous workers’ compensation claims for silicosis, which resulted after the workers were diagnosed by employer medical screening programs.

Cambria County Courthouse in Ebensburg, PA (venue for an outbreak of silicosis litigation in the 1980s and early 1990s5)

The first of the foundrymen’s cases was set for trial in 1989, 30 years ago, in Cambria County, Pennsylvania. The silica cases were on the docket of the President Judge, the Hon. Joseph O’Kicki, who turned out to be less than honorable. Just before the first silica trial, Judge O’Kicki was arrested on charges of corruption, as well as lewdness (for calling in his female staff while lounging in chambers in his panties).

As a result of O’Kicki’s arrest, the only Cambria Country trial we saw in 1989 was the criminal trial of Judge O’Kicki, in Northampton County. In April 1989, a jury found O’Kicki guilty of bribery and corruption, although it acquitted him on charges of lewdness.6 Facing a sentence of over 25 years, and a second trial on additional charges, O’Kicki returned to the land of his forebears, Slovenia, where he lived out his days and contributed to the surplus population.7

Whatever schadenfreude experienced by the defendants in the Cambria County silicosis litigation was quickly dispelled by the assignment of the silica cases to the Hon. Eugene Creany, who proved to be an active partisan for the plaintiffs’ cause. Faced with a large backlog of cases created by the rapacious filings of the Pittsburgh plaintiffs’ lawfirms, and Judge O’Kicki’s furlough from judicial service, Judge Creany devised various abridgements of due process, the first of which was to consolidate cases. As a result, the first case up in 1990 was actually three individual cases “clustered” for a single jury trial: Harmotta, Phillips, and Peterson.8 To poke due process in both eyes, Judge Creany made sure that one of the “clustered” cases was a death case (Peterson).

Jury selection started in earnest on April 2, 1990, with opening statements set for April 4. In between, the defense made the first of its many motions for mistrial, when defense lawyers observed one of the plaintiffs, Mr. Phillips, having breakfast with some of the jurors in the courthouse cafeteria. Judge Creany did not seem to think that this pre-game confabulation was exceptional, and admonished the defense that folks in Cambria County are just friendly, but they are fair. Trial slogged on for four weeks, with new abridgments of due process almost every day, such as forcing defendants, with adverse interests and positions, into having one direct- and one cross-examination of each witness. The last motion for mistrial was provoked by Judge Creany’s walking into the jury room during its deliberations, to deliver doughnuts.

At the end of the day, in May 1990, the jury proved to be much fairer than the trial judge. Judge Creany instructed the jury that “silica was the defect,” and on other novel points of law. Led by its foreman, a union organizer for the United Mine Workers, the jury returned a defense verdict in the Peterson case, which involved a claim that Mr. Peterson’s heart attack death case was caused by his underlying silicosis. In the two living plaintiffs’ cases, the jury found that the men had knowingly assumed the risk of silicosis, but at the judge’s insistence, the jury proceeded to address defendants’ liability, and to assess damages, in the amount of $22,500, in the two cases.

Pennsylvania’s appellate courts took a dim view of plaintiffs’ efforts to hold remote silica suppliers responsible for silicosis arising out of employment by large, sophisticated steel manufacturers. The Superior Court, Pennsylvania’s intermediate appellate court, reversed and remanded both plaintiffs’ verdicts. In Mr. Harmotta’s case, the court held that his action was collaterally estopped by a previous workman’s compensation judge’s finding that he did not have silicosis. In Mr. Phillip’s case, the court addressed the ultimate issue, whether a remote supplier to a sophisticated intermediary can be liable for silicosis that resulted from the intermediary’s employment and use of the supplied raw material. In what was a typical factual scenario of supply of silica to foundry employers, the Superior Court held that there was no strict or negligence liability for the employees’ silicosis.9 The Pennsylvania Supreme Court declined to hear Harmotta’s appeal on collateral estoppels, but heard an appeal in Phillips’ case. The Supreme Court pulled back from the sophisticated intermediary rationale for reversal, and placed its holding instead on the obvious lack of proximate cause between the alleged failure to warn and the claimed harm, given the jury’s special finding of assumed risk.10

One of plaintiffs’ counsel’s principal arguments, aimed at the union organizer on the jury, was that even if a warning to the individual plaintiffs might not have changed their behavior, a warning to the union would have been effective. The case law involving claims against unions for failing to warn have largely exculpated unions and taken them out of the warning loop. Given this case law, plaintiffs’ argument was puzzling, but the puzzlement turned to outrage when we learned after the first trial that Judge Creany had been a union solicitor, in which role, he had regularly written to U.S. Steel in Johnstown, to notify the employer when one of the local union members had been diagnosed with silicosis.

The next natural step seemed to list Judge Creany as a percipient fact witness to the pervasive knowledge of silicosis among the workforce and especially among the union leadership. Judge Creany did not take kindly to being listed as a fact witness, or being identified in voire dire as a potential witness. Still, the big lie about failure to warn and worker and labor union ignorance had been uncovered. Judge Creany started to delegate trials to other judges in the courthouse and to bring judges in from neighboring counties. The defense went on win the next dozen or so cases, before the plaintiffs’ lawyers gave up on their misbegotten enterprise of trying to use Pennsylvania’s hyperstrict liability rules to make remote silica suppliers pay for the fault of workers and their employers.

You won’t find any mention of the Cambria County saga in Rosner or Markowitz’s glorified accounts of silicosis litigation. The widespread unlawful screenings, the “double dipping” by asbestos claimants seeking a second paycheck for fabricated silicosis, the manufactured diagnoses and product identification do not rent space in Rosner and Markowitz’s fantastical histories.

Daubert Retrospective – Statistical Significance

January 5th, 2019

The holiday break was an opportunity and an excuse to revisit the briefs filed in the Supreme Court by parties and amici, in the Daubert case. The 22 amicus briefs in particular provided a wonderful basis upon which to reflect how far we have come, and also how far we have to go, to achieve real evidence-based fact finding in technical and scientific litigation. Twenty-five years ago, Rules 702 and 703 vied for control over errant and improvident expert witness testimony. With Daubert decided, Rule 702 emerged as the winner. Sadly, most courts seem to ignore or forget about Rule 703, perhaps because of its awkward wording. Rule 702, however, received the judicial imprimatur to support the policing and gatekeeping of dysepistemic claims in the federal courts.

As noted last week,1 the petitioners (plaintiffs) in Daubert advanced several lines of fallacious and specious argument, some of which was lost in the shuffle and page limitations of the Supreme Court briefings. The plaintiffs’ transposition fallacy received barely a mention, although it did bring forth at least a footnote in an important and overlooked amicus brief filed by American Medical Association (AMA), the American College of Physicians, and over a dozen other medical specialty organizations,2 all of which both emphasized the importance of statistical significance in interpreting epidemiologic studies, and the fallacy of interpreting 95% confidence intervals as providing a measure of certainty about the estimated association as a parameter. The language of these associations’ amicus brief is noteworthy and still relevant to today’s controversies.

The AMA’s amicus brief, like the brief filed by the National Academies of Science and the American Association for the Advancement of Science, strongly endorsed a gatekeeping role for trial courts to exclude testimony not based upon rigorous scientific analysis:

The touchstone of Rule 702 is scientific knowledge. Under this Rule, expert scientific testimony must adhere to the recognized standards of good scientific methodology including rigorous analysis, accurate and statistically significant measurement, and reproducibility.”3

Having incorporated the term “scientific knowledge,” Rule 702 could not permit anything less in expert witness testimony, lest it pollute federal courtrooms across the land.

Elsewhere, the AMA elaborated upon its reference to “statistically significant measurement”:

Medical researchers acquire scientific knowledge through laboratory investigation, studies of animal models, human trials, and epidemiological studies. Such empirical investigations frequently demonstrate some correlation between the intervention studied and the hypothesized result. However, the demonstration of a correlation does not prove the hypothesized result and does not constitute scientific knowledge. In order to determine whether the observed correlation is indicative of a causal relationship, scientists necessarily rely on the concept of “statistical significance.” The requirement of statistical reliability, which tends to prove that the relationship is not merely the product of chance, is a fundamental and indispensable component of valid scientific methodology.”4

And then again, the AMA spelled out its position, in case the Court missed its other references to the importance of statistical significance:

Medical studies, whether clinical trials or epidemiologic studies, frequently demonstrate some correlation between the action studied … . To determine whether the observed correlation is not due to chance, medical scientists rely on the concept of ‘statistical significance’. A ‘statistically significant’ correlation is generally considered to be one in which statistical analysis suggests that the observed relationship is not the result of chance. A statistically significant correlation does not ‘prove’ causation, but in the absence of such a correlation, scientific causation clearly is not proven.95

In its footnote 9, in the above quoted section of the brief, the AMA called out the plaintiffs’ transposition fallacy, without specifically citing to plaintiffs’ briefs:

It is misleading to compare the 95% confidence level used in empirical research to the 51% level inherent in the preponderance of the evidence standard.”6

Actually the plaintiffs’ ruse was much worse than misleading. The plaintiffs did not compare the two probabilities; they equated them. Some might call this ruse, an outright fraud on the court. In any event, the AMA amicus brief remains an available, citable source for opposing this fraud and the casual dismissal of the importance of statistical significance.

One other amicus brief touched on the plaintiffs’ statistical shanigans. The Product Liability Advisory Council, National Association of Manufacturers, Business Roundtable, and Chemical Manufacturers Association jointly filed an amicus brief to challenge some of the excesses of the plaintiffs’ submissions.7  Plaintiffs’ expert witness, Shanna Swan, had calculated type II error rates and post-hoc power for some selected epidemiologic studies relied upon by the defense. Swan’s complaint had been that some studies had only 20% probability (power) to detect a statistically significant doubling of limb reduction risk, with significance at p < 5%.8

The PLAC Brief pointed out that power calculations must assume an alternative hypothesis, and that the doubling of risk hypothesis had no basis in the evidentiary record. Although the PLAC complaint was correct, it missed the plaintiffs’ point that the defense had set exceeding a risk ratio of 2.0, as an important benchmark for specific causation attributability. Swan’s calculation of post-hoc power would have yielded an even lower probability for detecting risk ratios of 1.2 or so. More to the point, PLAC noted that other studies had much greater power, and that collectively, all the available studies would have had much greater power to have at least one study achieve statistical significance without dodgy re-analyses.
