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.
