 Legislative Initiatives – The Asbestos Fairness in Compensation Act

Over the years, Congress has considered various possible solutions to the problem of asbestos liability. One proposed reform bill, which bore the title “Asbestos Fairness in Compensation Act,” was specifically motivated by a concern about the quality of the expert opinions that fueled the asbestos litigation tsunami.[1] The Report by the Senate Judiciary Committee for this bill commented on its view of medical testimony in asbestos cases:

“Defendants’ rights are further compromised when courts lack the resources to monitor the medical evidence submitted by plaintiffs.  A study by neutral academics showed that forty-one (41 %) percent of audited claims of alleged asbestosis or pleural disease were found by trust physicians to have either no disease or a less severe disease than alleged by the plaintiffs’ experts (for example, pleural disease rather than asbestosis).”[2]

A key part of the bill sought to establish a process to ensure that claims would be based upon sound medical science.  As the Senate Report explained the legislative goal:

“4. Diagnostic and latency criteria

Asbestos claimants must meet diagnostic and latency criteria to be compensated by the Fund.  The diagnostic criteria should reflect the typical components of a true medical diagnosis by a claimant’s doctor, including an in-person physical examination (or pathology in the case where the injured person is deceased) and a review of the claimant’s medical, smoking and exposure history by the doctor diagnosing an asbestos-related disease.  These requirements ensure that the claimant will be given a meaningful diagnosis related to the claimant’s condition.  The diagnosis must also include consideration of other more likely causes of the condition to ensure that asbestos exposure was the cause of any claimed nonmalignant disease (as opposed to other industrial dust exposure) or a substantial contributing factor in causing a malignant disease….”[3]

A number of the bill’s specific provisions sought to limit payments to only claimants who could qualify under properly validated medical criteria. This bill, like all those before it, died on the Hill.

The Health Care Quality Improvement Act of 1986

In 1986, Congress passed the Health Care Quality Improvement Act (“HCQIA”)[4], which was prompted by concerns that fear of litigation would deter hospitals, physicians and others from carrying out peer review of unprofessional conduct and from providing candid assessments to peer review bodies.  The Act gave all participants in a qualifying “professional review action” immunity from being held liable in damages “under any law of the United States or of any State (or political subdivision thereof) with respect to the action.”[5]  One of the immunized entities is a “professional review body,” a term defined by HCQIA to mean “a health care entity and the governing body or any committee of a health care entity which conducts professional review activity, and includes any committee of the medical staff of such an entity when assisting the governing body in a professional review activity.”[6]  Moreover, another provision of the Act[7] provides immunity from damages to any person “providing information to a professional review body regarding the competence or professional conduct of a physician. . . .unless such information is false and the person providing it knew such information was false.”

The HCQIA has given rise to litigation over whether it protects professional review bodies from defamation cases involving litigation opinions. If medico-legal opinions are within the scope of the practice of medicine, then a potentially important method for curbing unscrupulous expert witnesses and false or exaggerated opinion testimony might consist of peer review actions through professional associations or state medical boards.

In Florida litigation, an intermediate appellate court held that the Florida Medical Association did not have immunity under the HCQIA for having provided procedures for pressing complaints against medical expert witnesses for unprofessional conduct.[8] The state law that might be invoked to curb meretricious testimony by licensed physicians, through professional associations or medical licensing boards, remains a hodge-podge.[9]

The American Bar Association’s Resolution Condemning Screenings and Calling For Impairment Criteria in Asbestos Litigation

Part of the impetus for federal legislative reform of asbestos litigation and its diagnostic gamesmanship came from an American Bar Association (ABA) recommendation of enacting impairment requirements for asbestos non-malignant personal injury cases.[10]  Acting upon concerns of court dockets backlogged by unimpaired and false-positive and bogus asbestosis cases, many of which arose out of mass screenings, the ABA urged that limitations rules be relaxed so as not to require the filing of unimpaired cases and that compensation be limited to cases that have demonstrable objective evidence of physical impairment due to asbestosis.  The ABA Report helped to instigate asbestos tort reform efforts in Congress, as well as several successful state legislative efforts.

State Tort Reform Acts for Reliable Diagnostic and Impairment Criteria in Asbestos and Silica Cases

While Congress floundered on litigation reform of the asbestos racket, several states enacted meaningful procedural and substantive changes to address some of the more abusive medical screening practices in asbestos and silica cases.  Texas, Georgia, Florida, and Ohio have enacted remedial legislation that requires a demonstration of objective pulmonary impairment.  In some instances, the tort reform measures specify that the diagnosing physician have a patient-physician relationship with the claimant.  This requirement was aimed at chilling the efforts of itinerant, out-of-state screening physicians, whose conduct came under scrutiny in In re Silica.[11]

Daubert, Its Progeny, and Amended Rule of Evidence 702

The Supreme Court’s opinion in Daubert was not only a watershed in the analysis of expert evidence generally but also reflected specific concerns about expert testimony in the area of product liability litigation. Daubert itself was a pharmaceutical product liability case, as were Joiner and Kumho Tire.  Medical causation is one of the key issues in every product liability case, and the pressure to produce an opinion, whether inculpatory or exculpatory, will occasionally distort a fragile epistemic foundation that will not support a conclusion with any certainty.  In In re Silica, the prospect of creating a mass tort out of whole cloth seems to have had just such a distorting influence.[12]

As noted by Judge Jack, in making the reliability inquiry, the trial judge has the responsibility “to make certain that an expert … employs in the courtroom the same level of intellectual rigor that characterizes the practice of an expert in the relevant field.”[13] Typically, this requirement of “intellectual rigor” means that physicians proffering a diagnosis for litigation purposes must employ the same standards and practices in reaching that diagnosis that they would use in their regular, non-litigation practice of medicine.

Judge Jack was not writing on a completely blank slate in finding the silicosis diagnoses to be bogus in the MDL cases. A few years earlier, the Fourth Circuit affirmed the exclusion of a physician expert witness who insisted upon a “hands-on” examination in his medical practice, but who did not bother to examine the plaintiff personally in a case involving a failed spinal fusion.[14] Standing alone, the physician expert witness’s failure to conduct a physical examination might not have required exclusion, but the deviation from his own established, non-litigation practice provided a persuasive showing that the expert witness “did not employ in the courtroom the same methods that he employs in his own practice,” which required exclusion.[15]

A similar example of gatekeeping occurred in Ingram v. Solkatronic Chemical, Inc.,[16] where the trial judge excluded the testimony of a medical expert witness who opined that plaintiff had been injured by exposure to arsine gas.  At his deposition, the expert witness “outlined his standard diagnostic protocol when called upon to evaluate a cause of a given physical ailment.”[17]  The witness’s own protocol included taking a medical history, performing a physical examination, and determining what tests were required.  This protocol starkly contrasted with the expert witness’s anemic litigation approach to diagnosis, which failed to include physical examinations or review of complete medical or occupational histories.  Finding that the expert’s procedures “depart[ed] from his own established diagnostic standards,” the court excluded his testimony.[18]

The Federal Multi-District Silicosis Proceedings Before Judge Janis Jack

One of the most significant developments in the role of scientific and medical evidence gatekeeping under Rule 702, and the Supreme Court’s decision in Daubert,[1] was the 2005 opinion of Judge Janis Graham Jack in the multi-district silicosis litigation.[2] Judge Jack’s lengthy opinion addresses a variety of procedural issues, including subject matter jurisdiction over some of the cases, but Her Honor’s focus was “whether the doctors who diagnosed Plaintiffs with silicosis employed a sufficiently reliable methodology for their testimony to be admissible” and “whether Plaintiffs’ counsel should be sanctioned for submitting unreliable diagnoses and failing to fully comply with discovery orders.”  Judge Jack held that thousands of diagnoses of silicosis were radically flawed and could not be treated as proper science or medicine, and she imposed sanctions against plaintiffs’ lawyers in the cases over which she had subject matter jurisdiction.

In summary, Judge Jack held that to pass the minimum reliability analysis under Daubert, a diagnosis of silicosis requires:

“(1) an adequate exposure to silica dust with an appropriate latency period,

(2) radiographic evidence of silicosis, and

(3) the absence of any good reason to believe that the radiographic findings are the result of some other condition (i.e., a differential diagnosis).

* * * * *

As discussed above, these three criteria are universally accepted, as demonstrated by learned treatises and experts in the field.  It is the implementation of these criteria in these cases which ranged from questionable to abysmal.”[3]

With respect to the first criterion, evidence of “adequate exposure to silica dust with an appropriate latency period,” the court concluded that “[t]he ‘exposure histories’ (or ‘work histories’) were virtually always taken by people with no medical training, who had significant financial incentives to find someone positive for exposure to silica (or asbestos, depending on which type of suit the employing law firm was seeking to file).”[4]  The court went on to state that:

“[t]hese ‘histories’ were devoid of meaningful details, such as the duration and intensity of exposure, which are critical to determining whether someone has sufficient exposure, dosage and latency to support a reliable diagnosis.”[5]

Judge Jack, who had been a registered nurse before going to law school and becoming a lawyer, was clearly concerned that the medical “histories were taken by receptionists [at medical screening companies allied with plaintiffs’ counsel] with no medical training.”[6]  The head of one of the screening companies “testified that the doctors who worked for his screening company simply relied upon the abbreviated work histories that [the screening company] supplied them.”[7]  As a former nurse, Judge Jack was probably more than a little put off by the screening company executive’s explanation that “to ask the doctor to take a work history in our field would be like asking [the defense attorney questioning him] to wash my car.  I mean it’s . . . very beneath him.”[8]  Judge Jack rejected this approach entirely, and found that legitimate doctors would find it necessary to take the occupational history themselves:

“This type of thorough, detailed, physician-guided work/exposure history is the kind of history that experts in the field of occupational medicine insist upon when diagnosing silicosis.  It is therefore the type of history required by the Federal Rules for these diagnoses to be admissible.  Cf. Allen v. Pennsylvania Eng’g Corp., 102 F.3d 194, 198 (5th Cir. 1996)… .”[9]

The second required predicate for an admissible diagnosis of silicosis was an appropriate radiographic finding – a so-called “B-read,” which is simply the interpretation of a physician, who has passed a certifying proficiency examination given by the National Institute of Occupational Health, for evaluating chest films for pneumoconiosis, using a standardized scale and notations.  Judge Jack discerned, contrary to the approach taken by some of the plaintiffs’ lawyers and certain doctors, that a positive B-read was not “a talisman that would dispel any doubts about the diagnoses as a whole.”[10]  A positive B-read simply is not sufficient alone to support a silicosis diagnosis.

Judge Jack noted that a consensus report of the American College of Occupational and Environmental Medicine rejected the use of a B-read alone as sufficient to support a diagnosis of pneumoconiosis, and emphasized the views of one testifying physician that the “ILO guidelines, by their express terms, [were] ‘not supposed to be used for designation of disease or determining compensation.’ ”[11] But even apart from rejecting the concept that a positive B-read was by itself a sufficient basis for a diagnosis of silicosis, Judge Jack fundamentally criticized the manner in which the X-rays at issue were conducted.

The B-reader system was not originally established for use in litigation, but as part of a coal workers’ surveillance program to determine whether a worker should be transferred to a low-dust environment.  And under this surveillance program, the worker is not transferred until at least two B-readers agree on a positive read.  But in most of these MDL cases, a single positive B-read was deemed sufficient by plaintiffs’ hired witnesses to establish a diagnosis of silicosis.[12]

Judge Jack also stressed that the methodology followed by the B-readers did “not correspond to the ILO’s recommended methodology for applying the ILO classification system, because according to ILO guidelines:

“When classifying radiographs for epidemiological purposes it is essential that the reader does not consider any information about the individuals concerned other than the radiographs themselves.  Awareness of supplementary details specific to the individuals themselves can introduce bias into the results.”[13]

In the cases before her, Judge Jack found that it was obvious that the so-called B-reader was “acutely aware of the precise disease he is supposed to be finding on the X-rays.  In these cases, the doctors repeatedly testified that they were told to look for silicosis, and the doctors did as they were told.”[14] Business pressures had obviously corrupted the diagnostic process, and resulted in improbable consistency in finding silicosis in whomever plaintiffs’ lawyers signed up for litigation.

This corrupt consistency, and obediency to retaining plaintiffs’ counsel, which led to Judge Jack’s approval of the testimony from the hearings that advanced the notion that some degree of blinding is needed to assure the integrity of the diagnostic process. When the radiographic films come from a mass screening, the readers should be confronted with films known to be negative through multiple, independent evaluations.

The third criterion given by Judge Jack for an admissible diagnosis of silicosis, was a proper “differential diagnosis,” which consisted of a showing of “the absence of any good reason to believe that the positive radiographic findings are the result of some other condition.”[15]

One of the physicians whose diagnoses were challenged claimed that this ruling out of other explanations for a radiographic pattern was not required for diagnosing silicosis, but Judge Jack found that this self-serving opinion was contradicted by the major textbooks in the field, by the physicians who showed up to testify in the hearings, and even by the plaintiffs’ own briefs. Judge Jack adverted to the language of Daubert to note that one factor to be considered in the “reliability” of an expert witness’s opinion was its general acceptance in the relevant scientific community.[16] The self-validating views of plaintiffs’ expert witnesses simply were not generally accepted in any legitimate segment of the medical profession. And thus Judge Jack found that, in the MDL cases, the plaintiffs’ expert witnesses’ failure to exclude other alternative causes of the radiographic findings clearly was not generally accepted in the field of occupational medicine, and that their opinions did not satisfy the requirements of Rule 702.[17] A proper differential diagnosis required what was lacking across the board in the cases, namely “a thorough occupational/exposure history and medical history,” as well as a social history that included travel destinations.[18]

In addition to Judge Jack’s carefully reasoned conclusions about the diagnostic “process” used by the challenged expert witnesses, Her Honor was presented with additional evidence of the egregious infirmity of the challenged diagnoses:

– The willingness of one doctor to render opinions on 1,239 plaintiffs in the MDL when he was admittedly not a qualified B-reader, not an expert in silicosis treatment, not qualified to read X-rays or CT scans, did no physical examinations, simply took whatever histories had been given to him by the plaintiffs’ lawyers, and spent a negligible amount of time reviewing each of the plaintiffs’ files.  The doctor testified that his practice consists almost entirely of litigation consulting and that he charges $600 per hour for that work.

– Another doctor’s abandonment of about 3,700 diagnoses under the scrutiny generated by the hearings before Judge Jack.

– The fact that 1,587 claimants who had previously been listed as having asbestosis, with no reference to silica disease, had their diagnoses changed to silicosis, with no reference to asbestos disease.  These diagnoses were produced rapidly and in large groups.

– The fact that a purported epidemic of silicosis apparently began abruptly in early 2001, when plaintiffs’ lawyers turned their attention to this alternative to asbestos litigation, and the fact that many of the silicosis claimants were recycled asbestosis clients of the plaintiffs’ firms.

The specific facts before Judge Jack may seem extreme, but the same or similar abuses have been commonplace in asbestos litigation for a long time before they were outed in the silicosis MDL.  The crucial holdings of In re Silica go beyond the serious depravity of the expert witnesses involved.

Raymark v. Stempel

In 1990, one now defunct asbestos product manufacturer, Raymark Industries, Inc. (“Raymark”), deluged with dubious lawsuits, brought RICO and other claims against medical professionals, lawyers, and claimants.[19]  Raymark based its allegations on deceptions that led it to settle an asbestos personal injury class action.

In ruling upon defendants’ motions to dismiss, the district court found that defendant medical screeners had disregarded standards set by the American Thoracic Society and reported that workers had asbestos-related “injuries” even thought the radiographic interpretations had no clinical significance.  The court stated that the screening program had produced a “steady flow of faulty claims” and was a “fraud on the court.”[20]  The court thus refused to dismiss Raymark’s claims based on common law fraud and RICO violations.[21]

Owens Corning Fiberglass Bankruptcy Proceedings

The efforts to curtail frivolous asbestos claims also include the motion by Credit Suisse in the Owens Corning bankruptcy for leave to file an adversary complaint against certain physicians who reported chest radiographs as positive for asbestos-related diseases.  This motion was granted conditionally on the agreement of Credit Suisse to indemnify Owens Corning for any potential ensuing liability, but then was withdrawn when Credit Suisse declined to provide such assurance.

Legal Remedies for Suspect Medical Science in Products Cases – Part One

June 2nd, 2020

Expert witness opinions about the nature and cause of plaintiffs’ medical conditions, are the linchpin of mass tort cases involving claims of bodily injury from allegedly harmful products.  The quality of these expert witness opinions has long been the subject of debate, but the explosion of products liability cases has brought increasing scrutiny, especially in cases involving asbestos, silica, and pharmaceutical claims.[1]

Courts, Congress, and commentators have raised concerns about the scientific and medical validity of the opinions offered in support of certain product liability claims, whether certain of the individuals who offer such opinions have a proper degree of independence from the lawyers representing the plaintiffs, and whether there is any way to address these questions apart from a rejection of the individual claims in which the bogus opinions are offered.  Famously, Judge Janis Jack of the United States District Court for the Southern District of Texas addressed these issues in a lengthy decision in which she excoriated physicians, medical screeners, and plaintiffs’ lawyers who she concluded had transgressed basic ground rules of medical and legal propriety in connection with silicosis claims.[2]

The stakes generated by the availability of these medical/technical opinions are especially high in mass torts that involve medical assessments of thousands of claimants.  The pendency of asbestos claims has driven well over 100 companies into bankruptcy, and with that example, any industry facing a substantial wave of repetitive liability claims must be concerned about how to respond to what it believes are false or unfounded claims. Clients ask whether there are remedies for the promotion of false, fraudulent, or just inadequate medical science under the banner of seeking compensation in products liability cases. The answers remain less than clear.

Some Past Attempts to Remedy the Harm from Dubious Science in Products Cases

GAF’s Litigation against the Asbestos Lawsuit Industry

On January 10, 2001, G-I Holdings Inc., the successor to GAF Corporation (“GAF”), filed suit against a group of asbestos personal injury lawyers who it alleged had “orchestrated a scheme to inundate the judicial system with hundreds of thousands of asbestos cases without regard to their merit.”[3] Among the allegations were claims that the plaintiffs’ firms had “suborned perjury and fabricated evidence” and “induced expert witnesses to provide false and misleading testimony, all for the purpose of extracting unwarranted and inflated settlements, judgments and, correspondingly, attorneys’ fees, from GAF and other asbestos defendants.”  The complaint alleged that, in 1978, a group of

“approximately 125 plaintiffs’ asbestos contingency fee attorneys banded together to form and fund the Asbestos Litigation Group (“ALG”) in order to further their scheme of promoting asbestos litigation.”  GAF asserted that “acting jointly through the ALG, and through less formal asbestos-related organizations, defendants, upon information and belief, solicited tens of thousands of asbestos claimants and sued manufacturers without regard for, or in conscious disregard of, the merits of their claims against particular individual defendants such as GAF. . . . .pursuant to agreements with each network [of local counsel] member, a share of the fees . . . .is typically channeled back to the referring ALG member, and ultimately to the ALG, to be invested  in future claimant solicitations, including mailed advertisements in newsletters.  This has resulted in the filing of further claims, thereby continuing the scheme, and increasing the network, which spirals ever larger.”

GAF’s complaint specifically included claims relating to the alleged “fabricat[ion]” of “medical evidence.”  In this regard, GAF alleged, upon information and belief, that the plaintiffs’ lawyers had:[4]

  1. . . . .induced medical “experts” to testify falsely. As set forth in the “Toxic Justice” report, [the plaintiffs’ law firm] paid off what one of the firm’s paralegals described as “whore docs” i.e., doctors who for money eagerly attributed virtually any lung abnormality to asbestos exposure, regardless of what medical evidence actually showed.

And GAF complained that:

  1. . . . . these practices induced false and misleading testimony to be given by expert witnesses in support of claims brought against GAF and others, which resulted in GAF’s payment of inflated verdicts and settlements in a number of cases.

While much of GAF’s complaint did not focus specifically on the quality of the medical evidence, it is nonetheless instructive as an overall perspective on the factual framework within which these medical issues arise. GAF’s complaint understandably focused heavily on defendant’s Baron & Budd’s memorandum, entitled “Preparing for Your Deposition.”  GAF alleged that this

“memorandum, apparently created for use in preparing asbestos plaintiffs for deposition, improperly exhorts witnesses to testify in a pre-scripted manner, regardless of the truth.”

For particularity’s sake, GAF alleged, with extensive quotations from the Baron & Budd memorandum, that the memorandum told

“witnesses to identify only those products listed on the Work History Sheets prepared by Baron & Budd (lest the witness identify the product of a bankrupt entity from whom no damages or attorneys’ fees could be collected). . . .and to memorize the product names provided by Baron & Budd on the “Work History Sheets” and to testify that they actually saw those names on containers where they worked. . . .”[5]

The complaint alleges that the memorandum gave further improper instructions to plaintiffs about their testimony, including directions to omit any mention of exposures resulting “from the replacement or removal of old product that could not be identified by brand”; making false claims of “equal exposure to all products”; denying “that they ever saw any warnings or had knowledge concerning the harmful effects of asbestos.”

GAF alleged a variety of other concerted actions to file false asbestos claims.  These activities allegedly included withholding “from production in discovery death certificates for asbestos claimants that did not support the conclusion that the individual had died as a result of an asbestos-related disease”; conducting “periodic in-house training sessions to teach other attorneys and/or paralegals how to prepare all asbestos claimants to give scripted testimony in their depositions. . . . .without regard for whether or not the testimony was true”; participating in a scheme to falsify Court records to indicate that complaints were filed before the running of the statute of limitations; and submitting affidavits containing false information concerning the identity of products.

The complaint also contained a number of allegations to the effect that the defendant law firms had “used their considerable resources and power in an attempt to intimidate and deter GAF (and others) from exercising their constitutionally protected rights to petition Congress in support of legislation that would establish a fair and efficient administrative facility for resolving legitimate asbestos claims without the years of delay and wasteful fees and transaction costs that are characteristic of the current system.  Defendants have waged a full-scale, multi-front war against those seeking passage of a Congressional bill entitled the “Fairness in Asbestos Compensation Act.”

The suit pled claims under the Racketeer Influenced and Corrupt Organizations Act (“RICO”),[6] and under numerous other headings of state, and federal, law.[7]  The lawsuit industry defendants brought a series of motions to dismiss on the pleadings, with successive amended complaints filed, until there was nothing left of GAF’s complaint.[8]  For example, part of the case – relating to the Baron & Budd memorandum discussed above — pleaded fraud based on information and belief.  Judge Sweet dismissed that aspect of the fraud claims on the grounds that Federal Rule of Civil Procedure 9(b) requires that allegations of fraud be pleaded with specificity and that the plaintiff must provide a statement of facts upon which the belief of the existence of fraud is founded.  Judge Sweet concluded that GAF had repeatedly failed to meet this requirement.

Federal and State Prosecutions against Physicians and Screening Companies

After Judge Jack’s exposé of fraudulent and false diagnoses in the silicosis MDL, various news media reported that the United States Attorney’s office in the Southern District of New York was investigating possible criminal charges against the physicians and lawyers who orchestrated the screenings. Historically, there has been little interest among prosecutors in the questionable activities of screening physicians, with some notable exceptions.  In 1990, the United States Attorney’s office, for the Eastern District of Philadelphia, filed a civil RICO against several Philadelphia-area physicians for their role in submitting false and fraudulent Medicare claims.[9]  As pleaded by the government, the fraudulent scheme consisted of soliciting industrial workers for “free” lung screening, at the behest of lawyer clients, for asbestos-related diseases.  The physicians conducted radiologic and pulmonary function examinations, and submitted requests to Medicare for reimbursement of inflated costs for these services and falsely stated that the services were reasonably medically necessary because of diagnoses of chronic obstructive pulmonary disease.[10]  This matter appears to have been resolved before trial, although the docket fails to reveal the exact nature of the resolution.

The false claim problem continues, although the silicosis screenings have abated, and most asbestos plaintiffs’ lawyers have shifted their efforts to the high-yield mesothelioma and lung cancer cases, for which diagnostic accuracy is not typically the dominant issue. Some within the lawsuit industry appear to continue the practice of referring clients to friendly physicians for an examination that will form the basis of a lawsuit, with the consulting physician in turn filing a request for reimbursement with the claimant’s private or public health insurer.  For most insurers, such a claim for reimbursement impliedly represents that the services were reasonably medically necessary, and sometimes the services may well be necessary.  At other times, the services are redundant and provided only for purposes of preparing the examining physician to serve as an expert witness.  In a case I tried early in my career, the testifying expert witness first saw the plaintiff two weeks before trial for no purpose other than to serve as a witness.  The plaintiff had a regular treating physician, and had been examined by another testifying witness, but the plaintiff’s lawyer wanted to have a second testifying witness for trial.  The “Saturday-night” expert witness conducted his examination, and then requested reimbursement for the examination from the plaintiff’s health insurer, and indicated the name of the plaintiff’s counsel as the “referring physician” on the insurance forms.  The trial judge remarkably would not permit cross-examination of the testifying expert witness on the fraud, and suggested that such cross-examination was prohibited by the collateral source rule!  The health insurance industry will occasionally act vigilantly to enforce a lien against a tort recovery, but there has been little evidence of civil or criminal litigation arising from the practice of billing insurers for examinations by physicians who are essentially expert witnesses and not treating physicians.

The Pennsylvania Silicosis Litigation Cock Up

In February 2002, Texas invaded Pennsylvania. No conventional weapons were fired. The Texans took up positions in mobile vans in motel parking lots across eastern Pennsylvania. Without prescriptions, physicians’ orders, or regulatory approval, the Texans directed unlawful X-ray radiation at Pennsylvania workers in the hopes of creating evidence to be used in lawsuits for silicosis. To help establish their litigation beachhead, the Texans hired local mercenaries – a New Jersey company in the business of providing mobile X-ray screenings. Dozens of silicosis lawsuits were created and filed in Philadelphia as a result of the invasion.

On January 25, 2007, the Commonwealth of Pennsylvania, through its Department of Environmental Protection (DEP), responded by fining the New Jersey company, MOST Health Services, Inc. The DEP found that MOST violated Pennsylvania law by conducting X-ray screenings without physician or regulatory approval. For having unlawfully exposed 161 persons to ionizing radiation, DEP assessed a civil penalty of $80,500.00, against MOST. The DEP did not charge the plaintiffs’ lawyers with any violation of Commonwealth regulations.

MOST’s participation in unlawful litigation screenings was not a momentary lapse in judgment. Back in 2000, defense counsel in asbestos cases compelled the testimony of MOST principal Kenneth Warner, who acknowledged then that MOST had not been in the practice of complying with screening regulations. Mr. Warner, however, claimed that the company was in the process of filing appropriate applications to comply.

Workers were invited to the February 2002 MOST screenings by their unions, but the invitation letters were written by Texas lawyers. To participate in the screenings, the workers had to sign a retainer agreement to engage the Texas-based law firm. The workers were told that “legal ethics” required that they hire the sponsoring law firm to represent them before “the attorneys can provide [them] with medical tests.”

Of course, the law in no state permits attorneys to provide medical tests, and especially not X-rays. DEP, like most other states’ regulatory agencies, has promulgated comprehensive regulations that govern virtually every aspect of the use of medical radiation. In Pennsylvania, anyone proposing a “healing arts screening” with X-rays must submit, in advance, a comprehensive, written proposal with details of the proposed screening, the description of the population to be examined, the qualifications of the radiation technician and operator, the quality control to be used, the qualifications of the supervising physician, and the identity and qualifications of the physician who will interpret the radiographs.

The MOST screenings, commissioned by the Texas lawyers, were never authorized by the DEP. No physician was present on site. None of the workers presented prescriptions or physicians’ orders before being unlawfully exposed to radiation. The identity of the physician slated to receive the chest radiographs was never disclosed to DEP.

Ultimately, the films created by MOST were sent to a West Virginia physician, well known and well compensated in dust-disease litigation. This off-site physician diagnosed virtually all of the workers with either asbestosis or silicosis, and a majority of litigants with both asbestosis and silicosis, although he never examined the workers, never interviewed them, and never reviewed their medical records.

In December 2005, the defendants in the silicosis cases that arose from the MOST screenings moved to dismiss on grounds that the claims were the direct result of unlawful activities that violated Pennsylvania public policy. The trial court denied the motion without opinion. Despite the obvious conspiracy between the plaintiffs’ lawyers and MOST to violate Pennsylvania health regulations, no disciplinary actions were brought against the plaintiffs’ lawyers in the cases.

The Pennsylvania fine against MOST seems to have been an exceptional finding. Although the predatory screening practices decried in federal Judge Janis Graham Jack’s now judicial opinion, In re Silica Products Liability Litigation, no other states to my knowledge have taken action against the conspiracies among lawyers, physicians, and mobile screening companies, to violate state health regulations. These conspiracies thrived for some time, in part because of the entrepreneurial enthusiasm of the conspirators, and the failure of courts, bar associations, adversary counsel, state and federal regulators, and medical societies to condemn the screening practices. In the context of silicosis litigation, the “red flags of fraud,” go beyond the manufacturing of diagnoses for money; they mark as dubious the entire enterprise of suing sand suppliers for failure to warn about hazards that were well known to government, industry, labor, and academia from the 1930s, forward.

ACGIH TLVs Lack Scientific Integrity & Transparency – The Mica NIC

June 2nd, 2020

The American Conference of Governmental Industrial Hygienists (ACGIH®) is a non-profit corporation established in 1938, to advance occupational and environmental health.  The corporation’s motto, included in its logo, hubristically announces:  “Defining the Science of Occupational and Environmental Health.”

Philosophers of science may demur from “the” in “the Science,” as well as from the intellectual arrogance in suggesting that this private organization has any such ability to commandeer the complex social nature of scientific knowledge. And yet, in the small area of setting permissible exposure limits to potential environmental or occupational toxic substances, the ACGIH is in the business of “defining” safety. Starting in 1941, the group started to review and recommend “exposure limits.” In 1956, the group coined (literally and figuratively) the term “threshold limit values” (TLVs®), and started to publish documentation for its recommended values.

From the beginning, the ACGIH has asserted that TLVs® are not standards; rather they are guidelines for use, with other information, in determining safe levels of workplace and environmental exposure. The ACGIH maintains that its TLVs are based upon published, peer-reviewed scientific studies in industrial hygiene, toxicology, occupational medicine, and epidemiology, without consideration for economic or technical feasibility.

Beginning in the 1980s, “the Lobby”[1] started to throw brushback pitches at the ACGIH to bully the organization out of positions that the Lobby thought were too comforting to manufacturing industry.[2]  The result was a dramatic shift in the ACGIH’s perspective. The bullying created a “white-hat” bias that operates as a one-way ratchet to push the ACGIH always to lower TLVs, regardless whether there was a scientific warrant for doing so. Efforts to curb ACGIH overreach by litigation have generally failed. The TLVs have becoming increasingly controversial and non-evidence-based.[3]

What follows is what a hypothetical stakeholder might submit in response to a recent ACGIH Notice of Intended change for its TLV for mica dust. Like other mineral dusts, mica when inhaled in large quantities over long time periods, causes a pneumoconiosis. Documenting a “reasonable safe” level requires studies with adequate quantification of exposure. I will leave the reader to decide whether the ACGIH has that evidence in hand, based upon the following.

**********************************************

These comments are in response to the proposed change in the ACGIH® TLV® for Mica, as explained in the ACGIH “Mica: TLV® Chemical Substances Draft Documentation, Notice of Intended Change” (“NIC”).  For the reasons stated below, the change in the Mica TLV-TWA (time-weighted average) in the NIC is not warranted and the existing Mica TLV should not be changed.

The ACGIH® TLVs® are important non-governmental standards, largely because a number of government entities incorporate TLVs by reference into regulations and thus give TLVs the force of law.[4]  For example, some states and Canadian provinces simply adopt TLVs as state or provincial occupational exposures levels, and some states have established “maximum allowable ambient concentrations” or similar limits on “toxic air contaminants” based entirely or in part on TLVs.  The U.S. Mine Safety and Health Administration (MSHA) uses the 1973 ACGIH TLV for crystalline silica (quartz) as a legally enforceable permissible exposure level.[5]  The U.S. Occupational Health and Safety Administration (OSHA) Hazard Communication Standard requires that ACGIH TLVs be disclosed in required Safety Data Sheets.  The process by which the ACGIH develops TLVs is critically important, and furthermore, given the regulatory and legal significance of the ACGIH TLVs, the ACGIH has the burden to support proposed changes in TLVs by an adequate process, which includes transparency and evidence sufficient to support any proposed change.

The flaws in the ACGIH TLV setting process are well known and the subject of several publications, most recently in paper titled “142 ACGIH Threshold Limit Values® established from 2008-2018 lack consistency and transparency.”

The following specific comments address the ACGIH’s process disclosed in the ACGIH’s NIC in support of its proposed change for the TLV-TWA for mica, which illustrate the process problem — the ACGIH NIC for the proposed Mica TLV-TWA change does not support the change proposed by the ACGIH.   Again, the ACGIH TLVs have regulatory and legal significance; therefore, the ACGIH should not make TLV changes arbitrarily and capriciously.  Instead, the changes should be made pursuant to a transparent process, and the ACGIH should support the proposed changes with the weight of the available evidence, and the evidence in support of and the reasons for the proposed change should be publicly disclosed.  It has not done that in this case, and its own NIC makes it clear that it has not:

  1. There is no evidence that “mica is an important cause of disabling occupational pneumoconiosis” as stated in the NIC. 

The NIC provides no citation or other supporting evidence for this conclusion; it merely states the conclusion as “fact” and a premise for the proposed change.[6] The NIC fails to estimate the number of workers currently potentially exposed to mica in the U.S. (or elsewhere), what industries these workers work in, what forms of mica these workers may be exposed to, what levels of respirable mica these workers may be exposed to, and to what extent pneumoconiosis caused by the inhalation of respirable mica exists.[7]

  1. The NIC proposes to materially lower the TLV for mica, but, other than noting that there are “nine different major species”, does not adequately address the mineralogical differences between the different species of mica, makes no attempt to assess the potential adverse health effects for the different species of mica, does not examine the “dose-response” data (as inadequate as it is) for the different species of mica, and so on. 

The “Chemical and Physical Properties” section of the NIC suggests the wide variety of materials that fall within the general term “mica”.  In spite of this, the ACGIH appears to have ignored differences and concluded that the TLV for “mica” as a general category of substances should be applicable to all forms of mica, with no support for this conclusion in the NIC.[8]

  1. The human studies (sic) cited in the NIC are inadequate to support a decision to change the mica TLV and do not support the mica TLV proposed.

The first cited study involved four employees in a muscovite milling plant, with an alleged exposure to respirable mica (as muscovite) dust between 1.86 and 5.77 mg/m3.

The second cited study involved a (one) South African man who worked in a mica milling factory.  As noted in the NIC, “[q]uantitative exposure data were not reported.”

The third cited study involved a (one) 65-year old who worked in the rubber industry for 40 years, where he was exposed to numerous dusts, including mica.  There was no exposure data reported.

The fourth study involved a (one) 62-year old woman allegedly exposed to “pure mica” for seven years; no quantitative exposure data were available.

The NIC cites the case of a worker who bagged mica flake for 36 years.  In this case, there were, apparently, two dust samples taken – one at the time of a medical exam of the worker at age 54, total dust of 0.2 mg/m3 — and one taken 17 years earlier – 0.7 mg/m3.  The bulk mica samples disclosed 7.1% to 8.4% silica (presumably, respirable crystalline silica as quartz).  The reference to the silica content of the “bulk samples” suggests that there was no analysis of the material collected in the two air samples taken.

The NIC cites the case of two British men who worked as “grinders of imported muscovite,” one starting in 1957. The “workplace dust concentrations were not quantified.”

The next paper cited in the NIC was from 1940 and involved employees who were exposed to the dust caused by “mica-scrap” grinding.  There was actually an attempt to quantify mica exposures (the data from before 1940), but it was done by particle count.  The NIC notes that the available information regarding mica health effects may be “limited by potential uncertainty converting from mppcf (million particles per cubic foot) to mg/m3 (which might not apply to all dust exposure scenarios).”  The difficulties associated with converting from mppcf to mg/m3 are well known in the cases of minerals far more extensively studied than mica (e.g., crystalline silica as quartz).  In addition to the conversion factor issue, there are other concerns raised by relying upon a paper published in 1940 to support a TLV today, such as, the quality of the sampling, the quality of the chest x-rays, and issues with the classification of the chest x-rays.  With that said, the NIC noted that “[n]one of the workers exposed at less than 10 mppcf (1.8 mg/m3), irrespective of employment duration, developed pneumoconiosis.”

The remaining studies cited in the NIC are similar.  But, to close this section of the comments, I will refer to the last study, a study of 71 South African workers employed in mica milling.  Twelve personal and static samples were taken during the course of the study.  The results of the personal samples indicated a range of respirable dust (or was it mica?) between 0.4 to 1.68 mg/m3.  The radiologic examination disclosed that 19 of the 71 workers had changes consistent with one or more of asbestos, silica and/or mica.  “The specific dust concentrations to which the individuals presenting with lung changes were exposed were not reported.”

The ACGIH is proposing a reduction in the mica TLV based on the studies as described in the NIC.  We submit that this is a process and transparency problem – there is simply no way to conclude that a reduction in the mica TLV is warranted based on the Human Studies (the “evidence”) cited in the NIC.  In most cases, the Human Studies are simply case reports involving one, two, or a few people, with no quantitative exposure data.  The studies with exposure data are inadequate, i.e., date from before 1940, and among other things measured exposure as mppcf, with one study literally including two samples.  Given the legal and regulatory significance of ACGIH TLVs, the evidence cited in support of the change in the mica TLV, and the reasonable conclusion that can be drawn from the evidence cited, should exceed some threshold and meet some burden.  The evidence in the NIC is grossly insufficient to support the proposed change.

  1. The NIC for mica does not disclose any evidence to support the proposed TLV of a TWA of 0.1 mg/m3. 

The comparison to OSHA’s notice of proposed rulemaking for occupational exposure to respirable crystalline silica (RCS) is instructive.  The supporting documentation sets forth a preliminary quantitative risk assessment outlining life-time risks for various disease end points associated with occupational exposure to RCS at various levels.  The preliminary quantitative risk assessment disclosed all of the underlying studies and methodology, sufficient to allow a reader to understand the basis for the risk assessment conclusions and agree or disagree with the conclusions.  Based on the risks (and other factors not considered by the ACGIH) set forth in the documentation, OSHA proposed a PEL (permissible exposure level) for RCS.

By contrast, the ACGIH simply contends for its proposed mica TLV: “Consequently, a TLV-TWA of 0.1 mg/m3 measured as respirable fraction (containing no asbestos and <1% crystalline silica) is recommended.”  The materials preceding “[c]consequently”, which in normal reading would be expected to support the conclusion following, are not a risk assessment or anything similar to one, and in no way even superficially support the conclusion – the recommendation – stated.[9]  Therefore, the ACGIH proposed a TLV-TWA of 0.1. The NIC materials do not support a TLV of 0.1 mg/m3, any more than they support a TLV of 0.0001 or 10.  It cannot be stated too emphatically that the NIC is devoid of any evidence to support any TLV, including the recommended TLV-TWA of 0.1 mg/m3.

Of course, the ACGIH TLV process is not a federal rulemaking.  And readers should be aware of the ACGIH Position Statement regarding TLVs (“TLVs … are not quantitative levels of risk at different exposure levels…”). But the same Position Statement notes that “TLVs®…represent conditions under which ACGIH® believes that nearly all workers may be repeatedly exposed without adverse health effects.”  So, presumably, the ACGIH concluded that its proposed mica TLV was that level, and yet there is simply no evidence in the NIC to support that conclusion.  Given the regulatory and legal significance of TLVs, the process of establishing TLVs should have some basis in science and evidence.

[7] By comparison, see the OSHA documentation for the NPRM for Occupational Exposure to Respirable Crystalline Silica published September 12, 2013.  The citation to the 1985 Skulberg article (in “Major Sources of Exposure”) is inadequate on its face in 2020; the article summarizes world mica use from 1905-1981, and provides no information regarding use post-1981.  Likewise, the citation to the “Campaign for Safe Cosmetics” does not provide information on occupational exposure.

[8] The case of crystalline silica again provides a useful contrast.  There is no ACGIH TLV for “crystalline silica,” which as a general term includes many polymorphs.

[9] Actually, the materials that precede “consequently” explicitly refute the conclusion stated by the ACGIH (the TLV-TWA of 0.1 mg/m3) — “the published literature has established an association between mica exposure and pneumoconiosis typically at concentrations in the range of 1-6 mg/m3,”  and “no cases were observed among workers exposed to mica dusts at concentrations of 1.8 mg/m3 or less….”

Judicial Dodgers – Rule 702 Tie Does Not Go to Proponent

June 2nd, 2020

The Advisory Committee notes to the year 2000 amendment to Federal Rule of Evidence 702 included a comment:

“A review of the case law after Daubert shows that the rejection of expert testimony is the exception rather than the rule. Daubert did not work a ‘seachange over federal evidence law’, and ‘the trial court’s role as gatekeeper is not intended to serve as a replacement for the adversary system’.”[internal citation omitted]

In stating its review of the caselaw, perhaps the Committee was attempting to allay the anxiety of technophobic judges. But was the Committee also attempting to derive an “ought” from an “is”?  Before the Supreme Court decided Daubert in 1993, virtually every admissibility challenge to expert witness opinion testimony failed. The trial courts were slow to adapt and to adopt the reframed admissibility standard. As the Joiner case illustrated, some Circuits were even slower to permit trial judges the discretion to assess the validity vel non of expert witnesses’ opinions.

The Committee’s observation about the “exceptional” nature of exclusions was thus unexceptional as a description of the case law before and shortly after Daubert was decided. And even if the Committee were describing a normative view, it is not at all clear how that view should translate into a ruling in a given case, without a very close analysis of the opinions at issue, under the Rule 702 criteria. In baseball, most hitters are thrown out at first base, but that fact does not help an umpire one whit in calling a specific runner “safe” or “out.”  Nonetheless, courts have repeatedly offered the observation about the exceptional nature of exclusion as both an explanation and a justification of their opinions to admit testimony.[1] The Advisory Committee note has thus mutated into a mandate to err on the side of admissibility, as though deliberately committing error was a good thing for any judge to do.[2] First rule: courts shall not err, not intentionally, recklessly, or negligently.

Close Calls and Resolving Doubts

Another mutant offspring of the “exception, not the rule” mantra is that “[a]ny doubts regarding the admissibility of an expert’s testimony should be resolved in favor of admissibility.”[3] Why not resolve the doubts and rule in accordance with the law? Or, if doubts remain, then charge them against the proponent who has the burden of showing admissibility? Unlike baseball, in which a tie goes to the runner, in expert witness law, a tie goes to the challenger because the defender of the motion has failed to show a preponderance in favor of admissibility. A better mantra: “exclusion when it is the Rule.”

Some courts re-imagine the Advisory Committee’s about exceptional exclusions as a recommendation for admitting Rule 702 expert witness opinion testimony as a preferred outcome. Again, that interpretation reverses the burden of proof and makes a mockery of equal justice and scientific due process.

Yet another similar judicial mutation is the notion that courts should refuse Rule 702 motions when they are “close calls.”[4] Telling the litigants that the call was close might help assuage the loser and temper the litigation enthusiasms of the winner, but it does not answer the key question: Did the proponent carry the burden of showing admissibility? Residual doubts would seem to weigh against the proponent.

Not all is lost. In one case, decided by a trial court within the Ninth Circuit, the trial judge explicitly pointed to the proponent’s failure to identify his findings and methodology as part of the basis for exclusion, not admission, of the challenged witness’s opinion testimony.[5] Difficulty in resolving whether the Rule 702 predicates were satisfied worked against, not for, the proponent, whose burden it was to show those predicates.

In another case, Judge David G. Campbell, of the District of Arizona, who has participated in the Rules Committee’s deliberations, showed the way by clearly stating that the exclusion of opinion testimony was required when the Rule 702 conditions were not met:

“Plaintiffs have not shown by a preponderance of the evidence that [the expert witness’s] causation opinions are based on sufficient facts or data to which reliable principles and methods have been applied reliably… .”[6]

Exclusion followed because the absent showings were “conditions for admissibility,” and not “mere” credibility considerations.

Trust Me, I’m a Liberal

One of the reasons that the Daubert Court rejected incorporating the Frye standard into Rule 702 was its view that a rigid “general acceptance” standard “would be at odds with the ‘liberal thrust’ of the Federal Rules.”[7] Some courts have cited this “liberal thrust” as though it explained or justified a particular decision to admit expert witness opinion testimony.[8]

The word “liberal” does not appear in the Federal Rules of Evidence.  Instead, the Rules contain an explicit statement of how judges must construe and apply the evidentiary provisions:

“These rules shall be construed to secure fairness in administration, elimination of unjustifiable expense and delay, and promotion of growth and development of the law of evidence to the end that the truth may be ascertained and proceedings justly determined.”[9]

A “liberal” approach, construed as a “let it all in” approach would be ill-designed to secure fairness, eliminate unjustifiable expense and time of trial, or lead to just and correct outcomes.  The “liberal” approach of letting in opinion testimony and let the jury guess at questions of scientific validiy would be a most illiberal result.  The truth will not be readily ascertained if expert witnesses are permitted to pass off hypotheses and ill-founded conclusions as scientific knowledge.

Avoiding the rigidity of the Frye standard, which was so rigid that it was virtually never applied, certainly seems like a worthwhile judicial goal. But how do courts go from the Justice Blackmun’s “liberal thrust” to infer a libertine “anything goes”? And why does liberal not connote seeking of the truth, free of superstitions? Can it be liberal to permit opinions that are based upon fallacious or flawed inferences, invalid studies, or cherry-picked data sets?

In reviewing the many judicial dodges that are used to avoid engaging in meaningful Rule 702 gatekeeping, I am mindful of Reporter Daniel Capra’s caveat that the ill-advised locutions used by judges do not necessarily mean that their decisions might not be completely justifiable on a carefully worded and reasoned opinion that showed that Rule 702 and all its subparts were met. Of course, we could infer that the conditions for admissibility were met whenever an expert witness’s opinions were admitted, and ditch the whole process of having judges offer reasoned explanations. Due process, however, requires more. Judges need to specify why they denied Rule 702 challenges in terms of the statutory requirements for admissibility so that other courts and the Bar can develop a principled jurisprudence of expert witness opinion testimony.

Judicial Dodgers – Weight not Admissibility

May 28th, 2020

Another vacuous response to a methodological challenge under Rule 702 is to label the challenge as “going to the weight, not the admissibility” of the challenged expert witness’s testimony. Of course, a challenge may be solely focused upon the expert witness’s credibility, such as when an expert witness testifies on many occasions only for one side in similar disputes, or for one whose political commitments render him unable to acknowledge the bona fides of any studies conducted by the adversarial parties.[1] If, however, the Rule 702 challenge stated an objection to the witness’s methodology, then the objection would count against both the opinion’s weight and its admissibility. The judicial “weight not admissibility” label conveys the denial of the challenge, but it hardly explains how and why the challenge failed under Rule 702. Applying such a label without addressing the elements of Rule 702, and how the challenged expert witness satisfied those elements, is often nothing less than a failure of judging.

The Flawed Application of a Generally Accepted Methodology

If a meretricious expert witness by pretense or ignorance invokes a standard methodology but does so in a flawed or distorted, or in an invalid way, then there will be a clear break in the chain of inferences from data to conclusion. The clear language of Rule 702 should render such an expert witness’s conclusion inadmissible. Some courts, however, retreat into a high level of generality about the method used rather than inspecting the method as applied. For example, a court might look at an expert witness’s opinion and correctly find that it relied upon epidemiology, and that epidemiology is a generally accepted discipline concerned with identifying causes. The specific detail of the challenge may have shown that the witness had relied upon a study that was thoroughly flawed,[2] or that the witness relied upon an epidemiologic study of a type that cannot support a causal inference.[3]

Rule 702 and the Supreme Court’s decision in Joiner make clear that the trial court must evaluate the expert witness’s application of methodology and whether it actually supports valid inferences leading to the witness’s claims and conclusions.[4] And yet, lower courts continue to characterize the gatekeeping process as “hands off” the application of methodology and conclusions:

“Where the court has determined that plaintiffs have met their burden of showing that the methodology is reliable, the expert’s application of the methodology and his or her conclusions are issues of credibility for the jury.”[5]

This rejection of the clear demands of a statute has infected even the intermediate appellate United States Court of Appeals. In a muddled application of Rule 702, the Third Circuit approved admitting expert witness testimony in a case, explaining “because [the objecting party / plaintiff] objected to the application rather than the legitimacy of [the expert’s] methodology, such objections were more appropriately addressed on cross-examination and no Daubert hearing was required”).[6] Such a ruling in the Third Circuit is especially jarring because it violates not only the clear language of Rule 702, but also established precedent within the Circuit that holds that “any step that renders the analysis unreliable . . . renders the expert’s testimony inadmissible. This is true whether the step completely changes a reliable methodology or merely misapplies that methodology.”[7]

The Eight Circuit seems to have set itself up stridently against the law by distinguishing between scientific methodologies and their applications, and holding that “when the application of a scientific methodology is challenged as unreliable under Daubert and the methodology itself is otherwise sufficiently reliable, outright exclusion of the evidence in question is warranted only if the methodology was so altered by a deficient application as to skew the methodology itself.”[8]

The Ninth Circuit similarly has followed this dubious distinction between methodology in the abstract and methodology as applied. In City of Pomona, the Circuit addressed the admissibility of an expert witness whose testing deviated from protocols. Relying upon pre-2000 Ninth Circuit case law, decided before the statutory language of Rule 702 was adopted, the court found that:

“expert evidence is inadmissible where the analysis is the result of a faulty methodology or theory as opposed to imperfect execution of laboratory techniques whose theoretical foundation is sufficiently accepted in the scientific community to pass muster under Daubert.”[9]

The Eleventh Circuit has similarly disregarded Rule 702 by adverting to an improvised distinction between validity of methodology and flawed application of methodology.[10]

Cherry Picking and Inadequate Bases

Most of the Circuits of the United States Court of Appeals have contributed to the mistaken belief that “[a]s a general rule, questions relating to the bases and sources of an expert’s opinion affect the weight to be assigned that opinion rather than its admissibility.”[11] Clearly, such questions can undermine the admissibility of an expert witness’s opinion under Rule 702, and courts need to say why they have found the challenged opinion to have had a “sufficient basis.” For example, in the notorious Milward case, the First Circuit, citing legally invalid pre-Daubert decisions, stated that “when the factual underpinning of an expert’s opinion is weak it is a matter affecting the weight and credibility of the testimony − a question to be resolved by the jury.”[12]

After Milward, the Eighth Circuit followed suit in a hormone replacement therapy case. An expert who ignored studies was excluded by the district court, but the Court of Appeals found an abuse of discretion, holding that the sufficiency of an expert’s basis is a question of weight and not admissibility.[13]

These rulings elevate form over substance by halting the gatekeeping inquiry at an irrelevant, high level of abstraction, and finding that the challenged expert witness was doing something “sciencey,” which is good enough for government work. The courts involved evaded their gatekeeping duties and ignored the undue selectivity in reliance materials and the inadequacy and insufficiency of the challenged expert witness’s factual predicate. The question is not whether expert witnesses relied upon “scientific studies,” but whether their causal conclusions and claims are well supported, under scientific standards, by the studies upon which they relied.

Like the covert shifting of the burden of proof, or the glib assessment that the loser can still cross-examine in front of the jury,[14] the rulings discussed represent another way that judges kick the can on Rule 702 motions. Despite the confusing verbiage, these judicial rulings are a serious deviation from the text of Rule 702, as well as the Advisory Committee Note to the 2000 Amendments, which embraced the standard articulated in In re Paoli, that

“any step that renders the analysis unreliable . . . renders the expert’s testimony inadmissible. This is true whether the step completely changes a reliable methodology or merely misapplies that methodology.”[15]

On a positive note, some courts have recognized that responding with the conclusory assessment of a challenge’s going to weight not admissibility is a delegation of the court’s gatekeeping duty to the jury.[16]

In 2018, Professor Daniel Capra, the Reporter to the Rules Committee addressed the “weight not admissibility dodge” at length in his memorandum to the Rules Committee:

“Rule 702 clearly states that these are questions of admissibility, but many courts treat them as questions of weight. The issue for the Committee is whether something/anything can be done about these wayward decisions.”[17]

The Reporter charitably noted that the problem could be in the infelicitous expression of some courts that short-circuit their analyses by saying “I see the problems, but they go to the weight of the evidence.”[18] Perhaps these courts meant to say that they had found that the proponent of the challenged expert witness testimony had shown admissibility by a preponderance, and that what non-disqualifying problems remained should be taken up on cross-examination.[19] The principle of charity, however, cannot exonerate federal judges from exercising the dodge repeatedly in the face of clear statutory language. Indeed, the Reporter reaffirmed the Rules Committee’s substantive judgment that questions of sufficient basis and reliable application of methodology are admissibility issues:[20]

“It is hard to see how expert testimony is reliable if the expert has not done sufficient investigation, or has cherry-picked the data, or has misapplied the methodology. The same ‘white lab coat’ problem − that the jury will not be able to figure out the expert’s missteps − would seem to apply equally to basis, methodology and application.”

Although the Reporter opined that some authors may have overstated judicial waywardness, he found the judicial disregard of the requirements of Rule 702(b) and (d) incontrovertible.[21]

Professor Capra restated his conclusions a year later, in 2019, when he characterized broad statements such as such as “challenges to the sufficiency of an expert’s basis raise questions of weight and not admissibility” as “misstatement[s] made by circuit courts in a disturbing number of cases… .”[22] Factual insufficiency and unreliable application of methodology are, of course, also credibility and ethical considerations, but they are the fact finders’ concern only after the proponent has shown admissibility by a preponderance of the evidence. Principled adjudication requires judges to say what they mean and mean what they say.

Inc., 613 F.3d 54 (1st Cir. 2010) (reversing exclusion of an expert witness who was biased in favor of plaintiffs in medical cases and who was generally affiliated with plaintiffs’ lawyers; such issues of personal bias are for the jury in assessing the weight of the expert witness’s testimony).

SKAPPOLOGY

May 26th, 2020

The Genetic Literacy Project (GLP) asks:

“Who is David and who is Goliath in the lobbying battle over agricultural biotechnology? Activists? Agro-business? In a commitment to transparency, the GLP has mined 5 years of data to help the public understand the funding network that shapes the biotechnology debate.”

The amount of money flowing into the campaign against genetically modified organisms (GMOs) is astonishing, but it does not stop the hypocritical complaints against industry’s sponsorship of studies to help show the safety of GMOs. In a recent on-line article, the GLP has published charts to map contributions from not-for-profit non-governmental organizations to anti-biotechnology advocacy groups. Close to a billion dollars ($850M) flowed into the coffers of these organizations from 2012 to 2016. The GLP’s work on tracking this funding is commendable for bringing balance to the debate about the effect of corporate money on health and environmental issues. Corporate includes the lawsuit industry and the advocacy industries.

Well actually, it would be a wonderful world if the GLP’s tracking were unnecessary. In one such alternative universe, people would ask to examine the evidence for and against claims, and they would have a healthy respect for uncertainty.

Studies funded by parties are routinely relied upon in litigation, and they are often pivotal in how courts decide significant claims of environmental or occupational harm.[1] Unfortunately, the sponsorship of studies by plaintiffs’ counsel, third-party litigation funding entities, and advocacy groups is often obscured or hidden.

* * * * * * * * * * * *

I recently happened upon an article of interest in an obscure journal, by a well-known author.[2]  The author, John C. Bailar, formerly an Editor-in-Chief of the Journal of the National Cancer Institute, was  professor emeritus in the University of Chicago’s Department of Public Health Sciences. He died in September 2016. Bailar was a graduate of the Yale University medical school, and also held a doctorate in statistics.

There is nothing ground breaking in Bailar’s article, but it is a nice summary of the ways that errors can creep into the scientific literature, short of actual fabrication or falsification of data.[3] It is also worth reading because it is an article that comes from one of the several Coronado Conferences, sponsored by an advocacy organization that has fraudulently concealed its funding, The Project on Scientific Knowledge and Public Policy, aka SKAPP.

To be sure, authors of SKAPP-funded articles have invariably cited their funding from SKAPP, and Bailar was no exception. Bailar made the following acknowledgements:

“Support for this paper was provided by The Project on Scientific Knowledge and Public Policy (SKAPP) at The George Washington University School of Public Health and Health Services. It is revised from a paper presented at SKAPP’s March 2006 Coronado Conference “Truth and Advocacy: The Quality and Nature of Litigation and Regulatory Science.” The papers from that conference will be published elsewhere.”[4]

The acknowledgement of support was rather anemic by SKAPP standards.  Most SKAPP-funded articles recited something closer to the following provided by David Michaels, who headed up SKAPP and worked as an expert witness for the litigation industry, until becoming the Administrator of the Occupational Health & Safety Administration, in President Obama’s administration:[5]

“DM [David Michaels] and CM [Celeste Monforton] are employed by the George Washington University School of Public Health and Health Services as part of the Project on Scientific Knowledge and Public Policy (SKAPP). Their salaries, in part, are funded by the Common Benefit Litigation Expense Trust, a fund established pursuant to a court order in the Silicone Gel Breast Implant Products Liability litigation. SKAPP’s funding is unrestricted; its funders are not given advance notice or the opportunity to review or approve any documents produced by the project. PL [Peter Lurie] is with Public Citizen’s Health Research Group.”

Michaels’ statement was perhaps a little more forthcoming, but few scientists or lay persons would know that his salary, and support, came from plaintiffs’ lawyers as part of an active litigation effort. Although Michaels claimed that the funding was unrestricted, like Big Tobacco funding, the sponsor, plaintiffs’ counsel, created a substantial selection effect in choosing beneficiaries who would deliver its pre-approved message. The Common Benefit Trust may sound like an eleemosynary, public-spirited, organization, with the imprimatur of the federal court system.  It was not.

Was Bailar influenced by his source of funding?  His topic would have permitted him many examples from the annals of science or litigation, but interestingly one of the few examples Bailar chose to give details about was a scientific dispute between the semiconductor industry and Richard Clapp, who was acting as an expert witness in litigation against that industry.  Although Clapp used a study design known to be inaccurate and biased, Bailar touted Clapp’s research over that sponsored by members of the industry.  Richard Clapp, in addition to have been an expert witness for the litigation industry on many occasions, also happened to have been a member of the SKAPP’s advisory committee. Hmmm.

Whence comes SKAPP funding?  SKAPP trades on most readers’ lack of familiarity with how “common benefit funds” are established.  They sound like some sort of disembodied charitable trust, such as the Pew. In fact, the silicone common benefit trust was nothing more than a funding device for mass federal litigation involving silicone breast implants. Ironically, the funding came from a litigation in which one leading judge described plaintiffs’ expert witnesses as “charlatans,” and the litigation claims as largely based upon fraud.[6] Cynics might believe that Bailar’s choice of Clapp versus the semiconductor industry, regardless of the merits, was driven by a desire to please SKAPP & Clapp.

The common benefit fund for the silicone-gel breast implant litigation was created by Order 13, “Establishing Plaintiffs’ Litigation Expense Fund to Compensate and Reimburse Attorneys for Services Performed and Expenses Incurred for Common Benefit.” The late Judge Sam Pointer, appointed to preside over MDL 926, In re Silicone Gel Breast Implants Products Liability Litigation, Master File No. CV 92-P-10000-S, entered the order on July 23, 1993.  Some of the pertinent terms of Order 13 illustrate how it was supposed to operate:

This order is entered in order to provide for the fair and equitable sharing among plaintiffs of the cost of special services performed and expenses incurred by attorneys acting for the common benefit of all plaintiffs.

  1. Plaintiffs’ Litigation Expense Fund to be Established. Plaintiffs’ National Liaison Counsel … are directed to establish an interest-bearing account to receive and disburse funds as provided in this order.

***

  1. Assessment.

(a)    All plaintiffs and their attorneys who, after this date, either agree — for a monetary consideration — to settle, compromise, dismiss, or reduce the amount of a claim or, with or without a trial, recover a judgment for monetary damages or other monetary relief, including both compensatory and punitive damages, with respect to a breast implant claim are hereby assessed:

(1)    5% of the “gross monetary recovery,” if the agreement is made or the judgment is entered after this date and before November 1, 1993, or

(2)    6% of the “gross monetary recovery,” if the agreement is made or the judgment is entered after October 31, 1993.

Defendants are directed to withhold this assessment from amounts paid to plaintiffs and their counsel, and to pay the assessment into the fund as a credit against the settlement or judgment.  ***

  1. Disbursements.

(a)    Payments may be made from the fund to attorneys who provide services or incur expenses for the joint and common benefit of plaintiffs in addition to their own client or clients.  Attorneys eligible are not limited to Plaintiffs’ National Liaison Counsel and members of Plaintiffs’ National Steering Committee, but include, for example, other attorneys called upon by them to assist in performing their responsibilities, State Liaison Counsel, and other attorneys performing similar responsibilities in state court actions in which the presiding state-court judge has imposed similar obligations upon plaintiffs to contribute to the fund.

(b)    Payments will be allowed only to compensate for special services performed, and to reimburse for special expenses incurred, for the joint and common benefit of all plaintiffs.

***

(c)    No amounts will be disbursed without review and approval by a committee of federal and state judicial officers to be designated by the court.  The committee may, however, utilize the services of a special master to assist in this review, and may authorize one or more of its members to act for the committee in approving particular types of applications for disbursement.

(d)    If the fund exceeds the amount needed to make payments as provided in this order, the court will order an refund to those who have contributed to the fund.  Any such refund will be made in proportion to the amount of the contributions.”

For a while, a defense lawyer, representing the defendants in the silicone MDL, participated in discussions concerning MDL 926 Order 13 funds, until the plaintiffs’ lawyers decided that his services were not needed, and excluded him from discussions of the use of the monies. The reality is that the plaintiffs’ lawyers in the silicone litigation were able to bamboozle the slim oversight committee into approving a propaganda campaign against Daubert gatekeeping, and that recipients of the plaintiffs’ lawyers’ largesse were able to misrepresent their funding as though it were from a federal court.

There are further ironies connected with the silicone common benefit trust.  First, the silicone litigation was effectively over when the court-appointed expert witnesses’ reports that announced that the plaintiffs’ expert witnesses lacked sound scientific evidence to support conclusions of causation.  SKAPP’s website reports that its activities started around 2002, by which time both the court-appointed witnesses, as well as the British Ministry of Health, and the Institute of Medicine’s select committee had reported that there was no basis for the plaintiffs’ causal claims in litigation.[7] The second irony is that SKAPP, through its sponsorship of various research and writing projects, had made the recipients of SKAPP money, by the terms of Order 13, agents of the silicone plaintiffs’ lawyers and their clients. Recipients of SKAPP funding who did not disclose that their support or salaries come from the coffers of plaintiffs’ counsel were engaged in misleading their readers and the scientific and legal communities.

I have written often in the past about SKAPP as an agent of plaintiffs’ counsel in mass tort litigation.[8] The concern is not new, but it has continuing significance because of the asymmetrical standard advanced by the lawsuit industry and its scientific advisors who seek to disqualify manufacturing industry and its scientific advisors from participating in scientific debate and argument about various health claims.[9]

Judicial Dodgers – Reassigning the Burden of Proof on Rule 702

May 13th, 2020

Explaining the denial of a Rule 702 motion in terms of the availability of cross-examination is just one among several dodges that judges use to avoid fully engaging with Rule 702’s requirements.[1] Another dodge involves shifting the burden of proof on admissibility from the proponent of the challenged expert witness to the challenger. This dodgewould appear to violate well-established law.

The Supreme Court, in deciding Daubert, made clear that the question whether an expert witness’s opinion was admissible was governed under the procedure set out in Federal Rule of Evidence 104(a).[2] The significance of placing the Rule 702 issues under the procedures set out in Rule 104(a) is that the trial judge must make the admissibility determination, and that he or she is not bound by the rules of evidence. The exclusion of the admissibility determination from the other rules of evidence means that trial judges can look at challenged expert witnesses’ relied-upon materials, and other facts, data, and opinions, regardless of these materials’ admissibility. The Supreme Court also made clear that the admissibility of an expert witness’s opinion testimony should be shown “by a preponderance of proof.”[3] Every court that has directly addressed the burden of proof issue in a Rule 702 challenge to expert witness testimony has clearly assigned that burden to the proponent of the testimony.[4]

Trial courts intent upon evading gatekeeping responsibility, however, have created a presumption of admissibility. When called upon to explain why they have denied Rule 702 challenges, these courts advert to the presumption as an explanation and justification for the denial.[5] Some courts even manage to discuss the burden of proof upon the proponent, and a presumption of admissibility, in almost the same breath.[6]

In his policy brief for amending Rule 702, Lee Mickus traces the presumption innovation to Borawick v. Shay, a 1995 Second Circuit decision that involved a challenge to hypnotically refreshed (or created) memory.[7] In Borawick, the Court of Appeals held that the plaintiff’s challenge turned upon whether Borawick’s testimony was competent or admissible, and that it did not involve the “the admissibility of data derived from scientific techniques or expert opinions.”[8] Nevertheless, in dicta, the court observed that “by loosening the strictures on scientific evidence set by Frye, Daubert reinforces the idea that there should be a presumption of admissibility of evidence.”[9]

Presumptions come in different forms and operate differently, and this casual reference to a presumption in dictum could mean any number of things. A presumption of admissibility could mean simply that unless there is a challenge to an expert witness’s opinion, the opinion is admissible.[10] The presumption could be a bursting-bubble (Thayer) presumption, which disappears once the opponent of the evidence credibly raises questions about the evidence’s admissibility. The presumption might be something that does not disappear, but once the admissibility is challenged, the presumption continues to provide some evidence for the proponent. And in the most extreme forms, the (Morgan) presumption might be nothing less than a judicially artful way of saying that the burden of proof is shifted to the opponent of the evidence to show inadmissibility.[11]

Although Borawick suggested that there should be a presumption, it did not exactly hold that one existed. A presumption in favor of the admissibility of evidence raises many questions about the nature, definition, and operation of the presumption. It throws open the question what evidence is needed to rebut the presumption. For instance, may a party whose expert witness is challenged not defend the witness’s compliance with Rule 702, stand on the presumption, and still prevail?

There is no mention of a presumption in Rule 702 itself, or in any Supreme Court decision on Rule 702, or in the advisory committee notes. Inventing a presumption, especially a poorly described one, turns the judicial discretion to grant or deny a Rule 702 challenge into an arbitrary decision.

Most importantly, given the ambiguity of “presumption,” a judicial opinion that denies a Rule 702 challenge by invoking a legal fiction fails to answer the question whether the proponent of the expert witness has carried the burden of showing that all the subparts of Rule 702 were satisfied by a preponderance of the evidence. While judges may prefer not to endorse or disavow the methodology of an otherwise “qualified” expert witness, their office requires them to do so, and not hide behind fictional presumptions.

Judicial Dodgers – The Crossexamination Excuse for Denying Rule 702 Motions

May 11th, 2020

In my last post,[1] I praised Lee Mickus’s recent policy paper on amending Rule 702 for its persuasive force on the need for an amendment, as well as a source for helping lawyers anticipate common judicial dodges to a faithful application of the rule.[2] There are multiple dodges used by judicial dodgers, and it behooves litigants to recognize and anticipate them. In this post, and perhaps future ones, I elaborate upon the concerns that Mickus documents.

One prevalent judicial response to the Rule 702 motion is to kick the can and announce that the challenge to an expert witness’s methodological shenanigans can and should be addressed by crossexamination. This judicial response was, of course, the standard one before the 1993 Daubert decision, but Justice Blackmun’s opinion kept it alive in frequently quote dicta:

“Vigorous cross-examination, presentation of contrary evidence, and careful instruction on the burden of proof are the traditional and appropriate means of attacking shaky but admissible evidence.”[3]

Justice Blackmun, no doubt, believed he was offering a “helpful” observation here, but the reality is quite different. Traditionally, courts allowed qualified expert witnesses to opine with wild abandon, after showing that they had the very minimal qualifications required to do so in court. In the face of this traditional judicial lassitude, “[v]igorous cross-examination, presentation of contrary evidence, and careful instruction on the burden of proof” were all a litigant could hope to accomplish in litigation. Furthermore, the litany of remedies for “shaky but admissible evidence” fails to help lower court judges and lawyers sort shaky but admissible evidence from shaky and inadmissible evidence.

Perhaps even more to the point, cases at common law “traditionally” did not involve multivariate logistic regression, structural equation models, propensity score weighting, and the like. Juries did just fine on whether Farmer Brown had exercised due care when he ran over his neighbor’s cow with his tractor, or even when a physician opined that a child was born 350 days after the putative father’s death was sired by the testator and entitled to inherit from “dad.”

Mickus is correct that a trial judge’s comment that the loser of a Rule 702 motion is free to cross-examine is often a dodge, an evasion, or an outright failure to engage with the intricacies of a complex methodological challenge.[4] Stating that the “traditional and appropriate means of attacking shaky but admissible evidence” remain available is a truism, and might be offered as judicial balm to the motion loser, but the availability of such means is hardly an explanation or justification for denying the Rule 702 motion. Furthermore, Justice Blackmun’s observation about traditional means was looking back at an era when in most state and federal court, a person found to be minimally qualified, could pretty much say anything regardless of scientific validity. That was the tradition that stood in active need of reform when Daubert was decided in 1993.

Mickus is also certainly correct that the whole point of judicial gatekeeping is that the presentation of vive voce testimony before juries is not an effective method for revealing shaky, inadmissible opinion testimony. A few courts have acknowledged that cross-examination in front of a jury is not an appropriate justification for admitting methodologically infirm expert witness opinion testimony. In the words of Judge Jed Rakoff, who served on the President’s Council of Advisors on Science and Technology,[5] addressed the limited ability of cross-examination in the context of forensic evidence:

“Although effective cross-examination may mitigate some of these dangers, the explicit premise of Daubert and Kumho Tire is that, when it comes to expert testimony, cross-examination is inherently handicapped by the jury’s own lack of background knowledge, so that the Court must play a greater role, not only in excluding unreliable testimony, but also in alerting the jury to the limitations of what is presented.”[6]

Judge Rakoff’s point is by no means limited to forensic evidence, and it has been acknowledged more generally by Professor Daniel Capra, the Reporter to the Advisory Committee on Evidence Rules:

“the key to Daubert is that cross-examination alone is ineffective in revealing nuanced defects in expert opinion testimony and that the trial judge must act as a gatekeeper to ensure that unreliable opinions don’t get to the jury in the first place.”[7]

Juries do not arrive at the court house knowledgeable about statistical and scientific methods; nor are they prepared to spend weeks going over studies to assess their quality, and whether an expert witness engaged in cherry picking, misapplying methodologies, or insufficient investigation.[8] In discussing the problem of expert witnesses’ overstating the strength of their opinions, beyond what is supported by evidence, the Reporter stressed the limits and ineffectiveness of remedial adversarial cross-examination:

“Perhaps another way to think about cross-examination as a remedy is to compare the overstatement issue to the issues of sufficiency of basis, reliability of methodology, and reliable application of that methodology. As we know, those three factors must be shown by a preponderance of the evidence. The whole point of Rule 702 — and the Daubert-Rule 104(a) gatekeeping function — is that these issues cannot be left to cross-examination. The underpinning of Daubert is that an expert’s opinion could be unreliable and the jury could not figure that out, even given cross-examination and argument, because the jurors are deferent to a qualified expert (i.e., the white lab coat effect). The premise is that cross-examination cannot undo the damage that has been done by the expert who has power over the jury. This is because, for the very reason that an expert is needed (because lay jurors need assistance) the jury may well be unable to figure out whether the expert is providing real information or junk. The real question, then, is whether the dangers of overstatement are any different from the dangers of insufficient basis, unreliability of methodology, and unreliable application. Why would cross-examination be insufficient for the latter yet sufficient for the former?

It is hard to see any difference between the risk of overstatement and the other risks that are regulated by Rule 702. When an expert says that they are certain of a result — when they cannot be — how is that easier for the jury to figure out than if an expert says something like ‘I relied on four scientifically valid studies concluding that PCB’s cause small lung cancer’. When an expert says he employed a ‘scientific methodology’ when that is not so, how is that different from an expert saying “I employed a reliable methodology” when that is not so?”[9]

The Reporter’s example of PCBs and small lung cancer was an obvious reference to the Joiner case, in which the Supreme Court held that the trial judge had properly excluded causation opinions. The Reporter’s point goes directly to the cross-examination excuse for not shirking the gatekeeping function. In Joiner, the Court held that gatekeeping was necessitated when cross-examination was insufficient in the face of an analytical gap between methodology and conclusion.[10] Indeed, such gaps are or should be present in most well-conceived Rule 702 challenges.

The problem is not only that juries defer to expert witnesses. Juries lack the competence to assess scientific validity. Although many judges are lacking in such competence, at least litigants can expect them to read the Reference Manual on Scientific Evidence before they read the parties’ briefs and the expert witnesses’ reports. If the trial judge’s opinion evidences ignorance of the Manual, then at least there is the possibility of an appeal. It will be a strange day in a stranger world, when a jury summons arrives in the mail with a copy of the Manual!

The rules of evidence permit expert witnesses to rely upon inadmissible evidence, at least when experts in their field would do so reasonably. To decide whether the reliance is reasonable requires the decision maker go outside the “proofs” that would typically be offered at trial. Furthermore, the decision maker – gatekeeper – will have to read the relied-upon study and data to evaluate the reasonableness of the reliance. In a jury trial, the actual studies relied upon are rarely admissible, and so the jury almost never has the opportunity to read them to make its own determination of reasonableness of reliance, or of whether the study and its data really support what the expert witness draws from it.

Of course, juries do not have to write opinions about their findings. They need neither explain nor justify their verdicts, once the trial court has deemed that there is the minimally sufficient evidence to support a verdict. Juries, with whatever help cross-examination provides, in the absence of gatekeeping, cannot deliver anything approaching scientific due process of law.

Despite Supreme Court holdings, a substantially revised and amended Rule 702, and clear direction from the Advisory Committee, some lower courts have actively resisted enforcing the requirements of Rule. 702 Part of this resistance consists in pushing the assessment of the reliability of the data and assumptions used in applying a given methodology out of the gatekeeping column and into the jury’s column. Despite the clear language of Rule 702, and the Advisory Committee Note,[11] some Circuits of the Court of Appeals have declared that assessing the reliability of assumptions and data is not judges’ work (outside of a bench trial).[12]

As Seinfeld has taught us, rules are like reservations. It is not enough to make the rules, you have to keep and follow them. Indeed, following the rule is really the important part.[13] Although an amended Rule 702 might include a provision that “we really mean this,” perhaps it is worth a stop at the Supreme Court first to put down the resistance.

For instance, cherry picking is reduced to a credibility issue for the jury and not germane to the court’s Rule 702 determination. In re Chantix Prods. Liab. Litig., 889 F. Supp. 2d 1272, 1288 (N.D.

Accordingly, I conclude that amended Rule 702 does not effect a change in the application of Daubert in the Third Circuit.”). Of course, if nothing changed, then the courts that take this position should be able to square their decisions with text of Rule 702, as amended in 2000.

Almost 27 years have passed since the United States Supreme Court issued its opinion in Daubert.[1] The holding was narrow. The Court reminded the Bar that Federal Rule of Evidence 702 was a statute, and that courts were thus bound to read it as a statute. The plain language of Rule 702 had been adopted by the Court in 1972, and then enacted by Congress, to be effective on July 1, 1975. Absent from the enacted Rule 702 was the “twilight zone” test articulated by a lower federal court in 1923.[2] In the Daubert case, the defense erroneously urged the application of the twilight zone test. In the post-modern way, the plaintiffs urged the application of no test.[3] The Court held simply that the twilight zone test had not been incorporated in the statutory language of Rule 702. Instead, the Court observed that the plain language of the statute imposed “helpfulness” and epistemic requirements for admitting expert witness opinion testimony.

It took another two Supreme Court decisions to flesh out the epistemic requirements for expert witnesses’ opinions,[4] and a third decision in which the Court told the Bench and Bar that the requirements of Rule 702 are “exacting.”[5] After the Supreme Court had added significantly to Rule 702’s helpfulness and knowledge requirements, the Advisory Committee revised the rule in 2000, to synthesize and incorporate these four Supreme Court decisions, and scholarly thinking about the patho-epistemology of expert witness opinion testimony. The Committee revised Rule 702 again in 2011, but only on “stylistic” issues, without any intent to add to or subtract from the 2000 rule.

Not all judges got the memo, or bothered to read and implement the revised Rule 702, in 2000. At both the District Court and the Circuit levels, courts persisted, and continue to persist, in citing retrograde decisions that predate the 2000 amendment, and even predate the 1993 decision in Daubert. Even the Supreme Court, in a 2011 opinion that did not involve the interpretation of Rule 702, was misled by a Solicitor General’s amicus brief, into citing one of the most anti-science, anti-method, post-modern, pre-Daubert, anything-goes decisions.[6] The judicial resistance to Rule 702 is well documented in many scholarly articles,[7] by the Reporter to the Advisory Committee,[8] and in the pages of this and other blogs.

In 2015, when evidence scholar David Bernstein argued that Rule 702 required amending,[9] I acknowledged the strength of his argument, but resisted because of what I perceived to be the danger of opening up the debate in Congress.[10] Professor Bernstein and lawyer Eric Lasker detailed and documented the many judicial dodges and evasions engaged in by many judges intent upon ignoring the clear requirements of Rule 702.

A paper published this week by the Washington Legal Foundation has updated and expanded the case for reform made by Professor Bernstein five years ago. In his advocacy paper, lawyer Lee Mickus has collated and analyzed some of the more recent dodges, which will depress the spirits of anyone who believes in evidence-based decision making.[11] My resistance to reform by amendment is waning. The meaning and intent of Rule 702 has been scarred over by precedent based upon judicial ipse dixit, and not Rule 702.

Mickus’s paper, like Professor Bernstein’s articles before, makes a persuasive case for reform, but this new paper does not evaluate the vagaries of navigating an amendment through the Advisory Committee, the Supreme Court, and Congress. Even if the reader is not interested in the amendment process, the paper can be helpful to the advocate in anticipating dodgy rule denialism.
