Echeverria Talc Trial – Crossexamination on Alleged Expert Witness Misconduct

October 21st, 2017

In a post-trial end-zone victory dance in Echeverria v. Johnson & Johnson, plaintiffs’ lawyer, Allen Smith proffered three explanations for the jury’s stunning $417 million verdict in his talc ovarian cancer case.1 One of the explanations asserted was Smith’s boast that he had adduced evidence that Johnson & Johnson’s expert witness on epidemiology, Douglas Weed, a former National Cancer Institute epidemiologist and physician, had been sanctioned in another, non-talc case in North Carolina, for lying under oath about whether he had notes to his expert report in that other case.2 Having now viewed Dr. Weed’s testimony3, through the Courtroom Video Network, I can evaluate Smith’s claim.

Weed’s allegedly perjurious testimony took place in Carter v. Fiber Composites LLC, 11 CVS 1355, N.C. Super. Ct., where he served as a party expert witness. In April 2014, Weed gave deposition testimony in the discovery phase of the Carter case. Although not served personally with a lawful subpoena, defense counsel had agreed to accept a subpoena for their expert witness to appear and produce documents, as was the local custom. In deposition, plaintiffs’ counsel asked Dr. Weed to produce any notes he created in the process of researching and writing his expert witness report. Dr. Weed testified that he had no notes. 

The parties disputed whether Dr. Weed had complied with a subpoena served upon defense counsel. The discovery dispute escalated and Dr. Weed obtained legal counsel, and submitted a sworn affidavit that denied the existence of notes. Plaintiffs’ counsel pressed on Dr. Weed’s understanding that he had no “notes.” In an Order, dated May 6, 2014, the trial court directed Dr. Weed to produce everything in his possession. In response to the order, Weed produced his calendar and a thumb drive with “small fragments of notes,” “inserts,” and “miscellaneous items.”

The North Carolina court did not take kindly to Dr. Weed’s confusion about whether his report “segments” and “inserts” were notes, or not. Dr. Weed viewed the segments and inserts to have been parts of his report, and later included within his report without any substantial change. The court concluded, however, that although Dr. Weed did not violate any court order, his assertion, in deposition, in an affidavit, and through legal counsel, was unreasonable, and directly related to his credibility in the Carter case. See Order Concerning Plaintiffs’ Motion for Sanctions Against Defendants and Non-Party Witness for Defendants (June 22, 2015) (Forrest D. Bridges, J.).

The upshot was that Dr. Weed and his counsel had provided false information to the court, on the court’s understanding of what had been requested in discovery. In the court’s view, Dr. Weed’s misunderstanding may have been understandable as a non-lawyer, but it was not reasonable for him to persist and have his counsel argue that there were no notes. The trial court specifically did not find that Dr. Weed had lied, as asserted by Allen Smith, but found that Weed’s conduct was undertaken intentionally or with reckless disregard of the truth, and that his testimony was an unacceptable violation of the oath to tell the whole truth. The trial court concluded that it could not sanction Dr. Weed personally, but its order specified that as a sanction, the plaintiffs’ counsel would be permitted to cross-examine Dr. Weed with the court’s findings and conclusions in the Carter case. Id. Not surprisingly, defense counsel withdrew Dr. Weed as an expert witness.

In the Echeverria case, the defense counsel did not object to the cross-examination; the video proceedings did not inform the viewers whether there had been a prior motion in limine concerning this examination. Allen Smith’s assertion about the North Carolina court’s findings was thus almost true. A cynic might say he too had not told the whole truth, but he did march Dr. Weed through Judge Bridges’ order of June 2015, which was displayed to the jury.

Douglas Weed handled the cross-examination about as well as possible. He explained on cross, and later on redirect, that he did not regard segments of his report, which were later incorporated into his report as served, to be notes. He pointed out that there was no information in the segments, which differed from the final report, or which was not included in the report. Smith’s cross-examination, however, had raised questions not so much about credibility (despite Judge Bridges’ findings), but about whether Dr. Weed was a “quibbler,” who would hide behind idiosyncratic understandings of important words such as “consistency.” Given how harmless the belatedly produced report fragments and segments were, we are left to wonder why Dr. Weed persisted in not volunteering them.

Smith’s confrontation of Dr. Weed with the order from the Carter case came at the conclusion of a generally unsuccessful cross-examination. Unlike the Slemp case, in which Smith appeared to be able to ask unfounded questions without restraint from the bench, in Echeverria, Smith drew repeated objections, which were frequently sustained. His response often was to ask almost the same question again, drawing the same objection and the same ruling. He sounded stymied and defeated.

Courtroom Video Network, of course, does not film the jurors, and so watching the streaming video of the trial offers no insights into how the jurors reacted in real time to Smith’s cross-examination. If Weed’s testimony was ignored or discredited by Smith’s cross-examination on the Carter order, then the Escheverria case cannot be considered a useful test of the plaintiffs’ causal claim. Dr. Weed had offered important testimony on methodological issues for conducting and interpreting studies, as well as inferring causation.

One of the peculiarities of the Slemp case was that the defense offered no epidemiologist in the face of two epidemiologists offered by the plaintiff. In Escheverria, the defense addressed this gap and went further to have its epidemiologist address the glaring problem of how any specific causal inference can be drawn from a risk ratio of 1.3. Dr. Weed explained attributable risk and probability of causation, and this testimony and many other important points went without cross-examination or contradiction. And yet, after finding general causation on a weak record, the jury somehow leaped over an insurmountable epistemic barrier on specific causation.

Multiplicity in the Third Circuit

September 21st, 2017

In Karlo v. Pittsburgh Glass Works, LLC, C.A. No. 2:10-cv-01283 (W. D. Pa.), plaintiffs claimed that their employer’s reduction in force unlawfully targeted workers over 50 years of age. Plaintiffs lacked any evidence of employer animus against old folks, and thus attempted to make out a statistical disparate impact claim. The plaintiffs placed their chief reliance upon an expert witness, Michael A. Campion, to analyze a dataset of workers agreed to have been the subject of the R.I.F. For the last 30 years, Campion has been on the faculty in Purdue University. His academic training and graduate degrees are in industrial and organizational psychology. Campion has served an editor of Personnel Psychology, and as a past president of the Society for Industrial and Organizational Psychology. Campion’s academic website page notes that he manages a small consulting firm, Campion Consulting Services1.

The defense sought to characterize Campion as not qualified to offer his statistical analysis2. Campion did, however, have some statistical training as part of his master’s level training in psychology, and his professional publications did occasionally involve statistical analyses. To be sure, Campion’s statistical acumen paled in comparison to the defense expert witness, James Rosenberger, a fellow and a former vice president of the American Statistical Association, as well as a full professor of statistics in Pennsylvania State University. The threshold for qualification, however, is low, and the defense’s attack on Campion’s qualifications failed to attract the court’s serious attention.

On the merits, the defense subjected Campion to a strong challenge on whether he had misused data. The defense’s expert witness, Prof. Rosenberger, filed a report that questioned Campion’s data handling and statistical analyses. The defense claimed that Campion had engaged in questionable data manipulation by including, in his RIF analysis, workers who had been terminated when their plant was transferred to another company, as well as workers who retired voluntarily.

Using simple z-score tests, Campion compared the ages of terminated and non-terminated employees in four subgroups, ages 40+, 45+, 50+, and 55+. He did not conduct an analysis of the 60+ subgroup on the claim that this group had too few members for the test to have sufficient power3Campion found a small z-score for the 40+ versus <40 age groups comparison (z =1.51), which is not close to statistical significance at the 5% level. On the defense’s legal theory, this was the crucial comparison to be made under the Age Discrimination in Employment Act (ADEA). The plaintiffs, however, maintained that they could make out a case of disparate impact by showing age discrimination at age subgroups that started above the minimum specified by the ADEA. Although age is a continuous variable, Campion decided to conduct z-scores on subgroups that were based upon five-year increments. For the 45+, 50+, and 55+ age subgroups, he found z-scores that ranged from 2.15 to 2.46, and he concluded that there was evidence of disparate impact in the higher age subgroups4. Karlo v. Pittsburgh Glass Works, LLC, C.A. No. 2:10-cv-01283, 2015 WL 4232600, at *11 (W.D. Pa. July 13, 2015) (McVerry, S.J.)

The defense, and apparently the defense expert witnesses, branded Campion’s analysis as “data snooping,” which required correction for multiple comparisons. In the defense’s view, the multiple age subgroups required a Bonferroni correction that would have diminished the critical p-value for “significance” by a factor of four. The trial court agreed with the defense contention about data snooping and multiple comparisons, and excluded Campion’s opinion of disparate impact, which had been based upon finding statistically significant disparities in the 45+, 50+, and 55+ age subgroups. 2015 WL 4232600, at *13. The trial court noted that Campion, in finding significant disparities in terminations in the subgroups, but not in the 40+ versus <40 analysis:

[did] not apply any of the generally accepted statistical procedures (i.e., the Bonferroni procedure) to correct his results for the likelihood of a false indication of significance. This sort of subgrouping ‘analysis’ is data-snooping, plain and simple.”

Id. After excluding Campion’s opinions under Rule 702, as well as other evidence in support of plaintiffs’ disparate impact claim, the trial court granted summary judgment on the discrimination claims. Karlo v. Pittsburgh Glass Works, LLC, No. 2:10–cv–1283, 2015 WL 5156913 (W. D. Pa. Sept. 2, 2015).

On plaintiffs’ appeal, the Third Circuit took the wind out of the attack on Campion by holding that the ADEA prohibits disparate impacts based upon age, which need not necessarily be on workers’ being over 40 years old, as opposed to being at least 40 years old. Karlo v. Pittsburgh Glass Works, LLC, 849 F.3d 61, 66-68 (3d Cir. 2017). This holding took the legal significance out of the statistical insignificance of Campion’s comparison 40+ versus <40 age-group termination rates. Campion’s subgroup analyses were back in play, but the Third Circuit still faced the question whether Campion’s conclusions, based upon unadjusted z-scores and p-values, offended Rule 702.

The Third Circuit noted that the district court had identified three grounds for excluding Campion’s statistical analyses:

(1) Dr. Campion used facts or data that were not reliable;

(2) he failed to use a statistical adjustment called the Bonferroni procedure; and

(3) his testimony lacks ‘‘fit’’ to the case because subgroup claims are not cognizable.

849 F.3d at 81. The first issue was raised by the defense’s claims of Campion’s sloppy data handling, and inclusion of voluntarily retired workers and workers who were terminated when their plant was turned over to another company. The Circuit did not address these data handling issues, which it left for the trial court on remand. Id. at 82. The third ground went out of the case with the appellate court’s resolution of the scope of the ADEA. The Circuit did, however, engage on the issue whether adjustment for multiple comparisons was required by Rule 702.

On the “data-snooping” issue, the Circuit concluded that the trial court had applied “an incorrectly rigorous standard for reliability.” Id. The Circuit acknowledged that

[i]n theory, a researcher who searches for statistical significance in multiple attempts raises the probability of discovering it purely by chance, committing Type I error (i.e., finding a false positive).”

849 F.3d at 82. The defense expert witness contended that applying the Bonferroni adjustment, which would have reduced the critical significance probability level from 5% to 1%, would have rendered Campion’s analyses not statistically significant, and thus not probative of disparate impact. Given that plaintiffs’ cases were entirely statistical, the adjustment would have been fatal to their cases. Id. at 82.

At the trial level and on appeal, plaintiffs and Campion had objected to the data-snooping charge on ground that

(1) he had engaged in only four subgroups;

(2) virtually all subgroups were statistically significant;

(3) his methodology was “hypothesis driven” and involved logical increments in age to explore whether the strength of the evidence of age disparity in terminations continued in each, increasingly older subgroup;

(4) his method was analogous to replications with different samples; and

(5) his result was confirmed by a single, supplemental analysis.

Id. at 83. According to the plaintiffs, Campion’s approach was based upon the reality that age is a continuous, not a dichotomous variable, and he was exploring a single hypothesis. A.240-241; Brief of Appellants at 26. Campion’s explanations do mitigate somewhat the charge of “data snooping,” but they do not explain why Campion did not use a statistical analysis that treated age as a continuous variable, at the outset of his analysis. The single, supplemental analysis was never described or reported by the trial or appellate courts.

The Third Circuit concluded that the district court had applied a ‘‘merits standard of correctness,’’ which is higher than what Rule 702 requires. Specifically, the district court, having identified a potential methodological flaw, did not further evaluate whether Campion’s opinion relied upon good grounds. 849 F.3d at 83. The Circuit vacated the judgment below, and remanded the case to the district court for the opportunity to apply the correct standard.

The trial court’s acceptance that an adjustment was appropriate or required hardly seems a “merits standard.” The use of a proper adjustment for multiple comparisons is very much a methodological concern. If Campion could reach his conclusion only by way of an inappropriate methodology, then his conclusion surely would fail the requirements of Rule 702. The trial court did, however, appear to accept, without explicit evidence, that the failure to apply the Bonferroni correction made it impossible for Campion to present sound scientific argument for his conclusion that there had been disparate impact. The trial court’s opinion also suggests that the Bonferroni correction itself, as opposed to some more appropriate correction, was required.

Unfortunately, the reported opinions do not provide the reader with a clear account of what the analyses would have shown on the correct data set, without improper inclusions and exclusions, and with appropriate statistical adjustments. Presumably, the parties are left to make their cases on remand.

Based upon citations to sources that described the Bonferroni adjustment as “good statistical practice,” but one that is ‘‘not widely or consistently adopted’’ in the behavioral and social sciences, the Third Circuit observed that in some cases, failure to adjust for multiple comparisons may “simply diminish the weight of an expert’s finding.”5 The observation is problematic given that Kumho Tire suggests that an expert witness must use “in the courtroom the same level of intellectual rigor that characterizes the practice of an expert in the relevant field.” Kumho Tire Co. v. Carmichael, 526 U.S. 137, 150, (1999). One implication is that courts are prisoners to prevalent scientific malpractice and abuse of statistical methodology. Another implication is that courts need to look more closely at the assumptions and predicates for various statistical tests and adjustments, such as the Bonferroni correction.

These worrisome implications are exacerbated by the appellate court’s insistence that the question whether a study’s result was properly calculated or interpreted “goes to the weight of the evidence, not to its admissibility.”6 Combined with citations to pre-Daubert statistics cases7, judicial comments such as these can appear to be a general disregard for the statutory requirements of Rules 702 and 703. Claims of statistical significance, in studies with multiple exposure and multiple outcomes, are frequently not adjusted for multiple comparisons, without notation, explanation, or justification. The consequence is that study results are often over-interpreted and over-sold. Methodological errors related to multiple testing or over-claiming statistical significance are commonplace in tort litigation over “health-effects” studies of birth defects, cancer, and other chronic diseases that require epidemiologic evidence8.

In Karlo, the claimed methodological error is beset by its own methodological problems. As the court noted, adjustments for multiple comparisons are not free from methodological controversy9. One noteworthy textbook10 labels the Bonferroni correction as an “awful response” to the problem of multiple comparisons. Aside from this strident criticism, there are alternative approaches to statistical adjustment for multiple comparisons. In the context of the Karlo case, the Bonferroni might well be awful because Campion’s four subgroups are hardly independent tests. Because each subgroup is nested within the next higher age subgroup, the subgroup test results will be strongly correlated in a way that defeats the mathematical assumptions of the Bonferroni correction. On remand, the trial court in Karlo must still make his Rule 702 gatekeeping decision on the methodological appropriateness of whether Campion’s properly considered the role of multiple subgroups, and multiple anaslyses run on different models.


1 Although Campion describes his consulting business as small, he seems to turn up in quite a few employment discrimination cases. See, e.g., Chen-Oster v. Goldman, Sachs & Co., 10 Civ. 6950 (AT) (JCF) (S.D.N.Y. 2015); Brand v. Comcast Corp., Case No. 11 C 8471 (N.D. Ill. July 5, 2014); Powell v. Dallas Morning News L.P., 776 F. Supp. 2d 240, 247 (N.D. Tex. 2011) (excluding Campion’s opinions), aff’d, 486 F. App’x 469 (5th Cir. 2012).

2 See Defendant’s Motion to Bar Dr. Michael Campion’s Statistical Analysis, 2013 WL 11260556.

3 There was no mention of an effect size for the lower aged subgroups, and a power calculation for the 60+ subgroup’s probability of showing a z-score greater than two. Similarly, there was no discussion or argument about why this subgroup could not have been evaluated with Fisher’s exact test. In deciding the appeal, the Third Circuit observed that “Dr. Rosenberger test[ed] a subgroup of sixty-and-older employees, which Dr. Campion did not include in his analysis because ‘[t]here are only 14 terminations, which means the statistical power to detect a significant effect is very low’. A.244–45.” Karlo v. Pittsburgh Glass Works, LLC, 849 F.3d 61, 82 n.15 (3d Cir. 2017).

4 In the trial court’s words, the z-score converts the difference in termination rates into standard deviations. Karlo v. Pittsburgh Glass Works, LLC, C.A. No. 2:10-cv-01283, 2015 WL 4232600, at *11 n.13 (W.D. Pa. July 13, 2015). According to the trial court, Campion gave a rather dubious explanation of the meaning of the z-score: “[w]hen the number of standard deviations is less than –2 (actually–1.96), there is a 95% probability that the difference in termination rates of the subgroups is not due to chance alone” Id. (internal citation omitted).

5 See 849 F.3d 61, 83 (3d Cir. 2017) (citing and quoting from Paetzold & Willborn § 6:7, at 308 n.2) (describing the Bonferroni adjustment as ‘‘good statistical practice,’’ but ‘‘not widely or consistently adopted’’ in the behavioral and social sciences); see also E.E.O.C. v. Autozone, Inc., No. 00-2923, 2006 WL 2524093, at *4 (W.D. Tenn. Aug. 29, 2006) (‘‘[T]he Court does not have a sufficient basis to find that … the non-utilization [of the Bonferroni adjustment] makes [the expert’s] results unreliable.’’). And of course, the Third Circuit invoked the Daubert chestnut: ‘‘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.’’ Daubert, 509 U.S. 579, 596 (1993).

6 See 849 F.3d at 83 (citing Leonard v. Stemtech Internat’l Inc., 834 F.3d 376, 391 (3d Cir. 2016).

7 See 849 F.3d 61, 83 (3d Cir. 2017), citing Bazemore v. Friday, 478 U.S. 385, 400 (1986) (‘‘Normally, failure to include variables will affect the analysis’ probativeness, not its admissibility.’’).

8 See Hans Zeisel & David Kaye, Prove It with Figures: Empirical Methods in Law and Litigation 93 & n.3 (1997) (criticizing the “notorious” case of Wells v. Ortho Pharmaceutical Corp., 788 F.2d 741 (11th Cir.), cert. denied, 479 U.S. 950 (1986), for its erroneous endorsement of conclusions based upon “statistically significant” studies that explored dozens of congenital malformation outcomes, without statistical adjustment). The authors do, however, give an encouraging example of a English trial judge who took multiplicity seriously. Reay v. British Nuclear Fuels (Q.B. Oct. 8,1993) (published in The Independent, Nov. 22,1993). In Reay, the trial court took seriously the multiplicity of hypotheses tested in the study relied upon by plaintiffs. Id. (“the fact that a number of hypotheses were considered in the study requires an increase in the P-value of the findings with consequent reduction in the confidence that can be placed in the study result … .”), quoted in Zeisel & Kaye at 93. Zeisel and Kaye emphasize that courts should not be overly impressed with claims of statistically significant findings, and should pay close attention to how expert witnesses developed their statistical models. Id. at 94.

Lawsuit Magic – Turning Talcum into Wampum

August 27th, 2017

Last week, a Los Angeles jury, with little prior experience in giving away other people’s money, awarded Eva Echeverria $417,000,000 dollars, in compensatory and punitive damages.1 Pundits in the media, and from both sides of the bar, including your humble blogger, jumped in to offer their speculation about the cause of profligacy.2

In speaking to one reporter, I described the evidence against Johnson & Johnson in an earlier trial (Slemp) as showing that the company needed to engage more fully with the scientific evidence, and not reduce complex evidence to sound bites. Alas, no good deed goes unpunished; my comments were reduced to sound bites! The reporter quoted me in part as having said that the case was a tough one for the defense, but left out that I thought the case was tough because the defense will have a difficult time educating judges and juries in the scientific methods and judgment needed to reach a sound conclusion. The reporter suggested that I had opined that the evidence against J & J was “compelling,” when I had suggested the evidence was confounded and biased, and that J & J needed to take greater care in addressing study validity.3

Perhaps more interesting than my speculation is the guesswork of the plaintiffs’ counsel, who has had more experience with conjecture than I will ever enjoy. In an interview with an American Law Media reporter4, Allen Smith offered his view that three “new” pieces of evidence explain the Los Angeles hyper-verdict:

1. evidence that other companies selling consumer talcum power have begun to place ovarian cancer warnings on their packaging, within the few months;

2. evidence that two persons involved in the Cosmetic Industry Review, which has concluded that talcum powder is safe, had received payments from Johnson & Johnson for speaking engagements; and

3. evidence that Douglas Weed, a former National Cancer Institute epidemiologist, who testified for Johnson & Johnson as an expert witness in the Echeverria case, had been sanctioned in another, non-talc case in North Carolina, for lying under oath about whether he had notes to his expert report in that other case.

Smith claimed that the new evidence was “very compelling,” especially the evidence that Johnson & Johnson had presented “unbelievable and non-credible witnesses on an issue so important like this.”

Now, Smith was trial counsel. He was intimately involved in presenting the evidence, and in watching the jurors’ reactions. Nonetheless, I am skeptical that these three “bits” explain the jury’s extravagance.

The first “bit” seems completely irrelevant. The fact of another company’s having warned within months of the trial, and years after the plaintiff was diagnosed with ovarian cancer, suggests that the evidence was inflammatory without having any probative value. Feasibility of warning was not an issue. State of the art was an issue. In the Slemp trial, Graham Colditz testified that he had had his epiphany that talc causes ovarian cancer only two years ago, when he was instructed by plaintiffs’ counsel to formulate an opinion on the causal claim. That another company recently placed a warning to ward off the lawsuit industry is hardly evidence of industry or governmental standard. All that can really be said is that some companies have been bullied or scared into warnings by the Lawsuit Industry, in the hopes of avoiding litigation. Indeed, it is not at all clear how this bit of irrelevancy was admitted into evidence. All in all, this evidence of a recent warning, years after the plaintiff’s use of the defendant’s talcum powder seems quite out of bounds.

The second bit was simply more of the same inflammatory, scurrilous attacks on Johnson & Johnson. Having watched much of the Slemp trial, I can say that this was Allen Smith’s stock in trade. From media reports, he seemed to have succeeded in injecting his personal attacks on the most peripheral of issues into the Echeverria trial. Not everything in Slemp was collateral attack, but a lot was, and much of it was embarrassing to the legal system for having tolerated it.

The third bit of evidence about Dr. Weed’s having been sanctioned was news to me. A search on Westlaw and Google Scholar failed to find the sanctions order referred to by plaintiffs’ counsel. If anyone is familiar with the North Carolina case that gave rise to the alleged court sanction, please send me a copy or a citation.

WOE — Zoloft Escapes a MDL While Third Circuit Creates a Conceptual Muddle

July 31st, 2017

Multidistrict Litigations (MDLs) can be “muddles” that are easy to get in, but hard to get out of. Pfizer and subsidiary Greenstone fabulously escaped a muddle through persistent lawyering and the astute gatekeeping of a district judge, in the Eastern District of Pennsylvania. That judge, the Hon. Cynthia Rufe, sustained objections to the admissibility of plaintiffs’ epidemiologic expert witness Anick Bérard. When the MDL’s plaintiffs’ steering committee (PSC) demanded, requested, and begged for a do over, Judge Rufe granted them one more chance. The PSC put their litigation industry eggs in a single basket, carried by statistician Nicholas Jewell. Unfortunately for the PSC, Judge Rufe found Jewell’s basket to be as methodologically defective as Bérard’s, and Her Honor excluded Jewell’s proffered testimony. Motions, paper, and appeals followed, but on June 2, 2017, the Third Circuit declared that the PSC and its clients had had enough opportunities to get through the gate. Their baskets of methodological deplorables were not up to snuff. In re Zoloft Prod. Liab. Litig., No. 16-2247 , __ F.3d __, 2017 WL 2385279, 2017 U.S. App. LEXIS 9832 (3d Cir. June 2, 2017) (affirming exclusion of Jewell’s dodgy opinions, which involved multiple methodological flaws and failures to follow any methodology faithfully) [Slip op. cited below as Zoloft].

Plaintiffs Attempt to Substitute WOE for Depressingly Bad Expert Witness Opinion

The ruse of conflating “weight of the evidence,” as used to describe the appellate standard of review for sustaining or reversing a trial court’s factual finding with a purported scientific methodology for inferring causation, was on full display by the PSC in their attack on Judge Rufe’s gatekeeping. In their appellate brief in the Court of Appeals for the Third Circuit, the PSC asserted that Jewell had used a “weight of the evidence method,” even though that phrase, “weight of the evidence” (WOE) was never used in Jewell’s litigation reports. The full context of the PSC’s argument and citations to Milward make clear a deliberate attempt to conflate WOE as an appellate judicial standard for reviewing jury fact finding and a purported scientific methodology. See Appellants’ Opening Brief at 54 (Aug. 10, 2016) [cited as PSC] (asserting that “[a]t all times, the ultimate evaluation of the weight of the evidence is a jury question”; citing Milward v. Acuity Specialty Products Group, Inc., 639 F.3d 11, 20 (1st Cir. 2011), cert. denied, 133 S. Ct. 63 (2012).

Having staked the ground that WOE is akin to a jury’s factual finding, and thus immune to any but the most extraordinary trial court action or appellate intervention, the PSC then pivoted to claim that Jewell’s WOE-ful method was nothing much more than an assessment of “the totality of the available scientific evidence, guided by the well-accepted Bradford-Hill criteria.” PSC at 3, 4, 7. This maneuver allowed the PSC to argue, apparently with a straight face, that WOE methodology as used by Jewell, had been generally accepted in the scientific community, as well as by the Third Circuit, in previous cases in which the court accepted the use of Bradford Hill’s considerations as a reliable method for establishing general causation. See PSC at 4 (citing Gannon v. United States, 292 F. App’x 170, 173 n.1 (3d Cir. 2008)). Jewell then simply plugged in his expertise and “40 years of experience,” and the desired conclusion of causation popped out. Id. Quod erat demonstrandum.

In pressing its point, the PSC took full advantage of loose, inaccurate language from the American Law Institute’s Restatement’s notorious comment C:

No algorithm exists for applying the Hill guidelines to determine whether an association truly reflects a causal relationship or is spurious.”

PSC at 33-34, citing Restatement (Third) of Torts: Physical and Emotional Harm § 28 cmt. c(3) (2010). Well true, but the absence of a mathematical algorithm hardly means that causal judgments are devoid of principles and standards. The PSC was undeterred, by text or by shame, from equating an unarticulated use of WOE methodology with some vague invocation of Bradford Hill’s considerations for evaluating associations for causality. See PSC at 43 (citing cases that never mentioned WOE but only Bradford Hill’s 50-plus year old heuristic as somehow supporting the claimed identity of the two approaches)1.

Pfizer Rebuffs WOE

Pfizer filed a comprehensive brief that unraveled the PSC’s duplicity. For unknown reasons, tactical or otherwise, however, Pfizer did not challenge the specifics of PSC’s equation of WOE with an abridged, distorted application of Bradford Hill’s considerations. See generally Opposition Brief of Defendants-Appellees Pfizer Inc., Pfizer International LLC, and Greenstone LLC [cited as Pfizer]. Perhaps given page limits and limited judicial attention spans, and just how woefully bad Jewell’s opinions were, Pfizer may well have decided that a more directed approach of assuming arguendo WOE’s methodological appropriateness was a more economical, pragmatic approach. A close reading of Pfizer’s brief, however, makes clear that it never conceded the validity of WOE as a scientific methodology.

Pfizer did point to the recasting of Jewell’s aborted attempt to apply Bradford Hill considerations as an employment of WOE methodology. Pfizer at 46-47. The argument reminded me of Abraham Lincoln’s famous argument:

How many legs does a dog have if you call his tail a leg?

Four.

Saying that a tail is a leg doesn’t make it a leg.”

Allen Thorndike Rice, Reminiscences of Abraham Lincoln by Distinguished Men of His Time at 242 (1909). Calling Jewell’s supposed method WOE or Bradford Hill or WOE/Bradford Hill did not cure the “fatal methodological flaws in his opinions.” Pfizer at 47.

Pfizer understandably and properly objected to the PSC’s attempt to cast Jewell’s “methodology” at such a high level of generality that any consideration of the many instances of methodological infidelity would be relegated to mere jury questions. Acquiescence in the PSC’s rhetorical move would constitute a complete abandonment of the inquiry whether Jewell had used a proper method. Pfizer at 15-16.

Interestingly, none of the amici curiae addressed the slippery WOE arguments advanced by the PSC. See generally Brief of Amici Curiae American Tort Reform Ass’n & Pharmaceutical Research and Manufacturers of America (Oct. 18, 2016); Brief of Washington Legal Fdtn. as Amicus Curiae (Oct. 18, 2016). There was no meaningful discussion of WOE as a supposedly scientific methodology at oral argument. See Transcript of Oral Argument in In re Zoloft Prod. Liab. Litig., No. 16-2247 (Jan. 25, 2017).

The Third Circuit Acknowledges that Some Methodological Infelicities, Flaws, and Fallacies Are Properly the Subject of Judicial Gatekeeping

Fortunately, Jewell’s methodological infidelities were easily recognized by the Circuit judges. Jewell treated multiple studies, which were nested within one another, and thus involved overlapping and included populations, as though they were independent verifications of the same hypothesis. When the population at issue (from the Danish cohort) was included in a more inclusive pan-Scandivanian study, the relied-upon association dissipated, and Jewell utterly failed to explain or account for these data. Zoloft at 5-6.

Jewell relied upon a study by Anick Bérard, even though he later had to concede that the study had serious flaws that invalidated its conclusions, and which flaws caused him to have a lack of confidence in the paper’s findings.2 In another instance, Jewell relied innocently upon a study that purported to report a statistically significant association, but the authors of this paper were later required by the journal, The New England Journal of Medicine, to correct the very calculated confidence interval upon which Jewell had relied. Despite his substantial mathematical prowess, Jewell missed the miscalculation and relied (uncritically) upon a finding as statistically significant when in fact it was not.

Jewell rejected a meta-analysis of Zoloft studies for questionable methodological quibbles, even though he had relied upon the very same meta-analysis, with the same methodology, in his litigation efforts involving Prozac and birth defects. Not to be corralled by methodological punctilio, Jewell conducted his own meta-analysis with two studies Huybrechts (2014) and Jimenez-Solem (2012), but failed to explain why he excluded other studies, the inclusion of which would have undone his claimed result. Zoloft at 9. Jewell purported to reanalyze and recalculate point estimates in two studies, Jimenez-Solem (2012) and Huybrechts (2014), without any clear protocol or consistency in his approach to other studies. Zoloft at 9. The list goes on, but in sum, Jewell’s handling of these technical issues did not inspire confidence, either in the district or in the appellate court.

WOE to the Third Circuit

The Circuit gave the PSC every conceivable break. Because Pfizer had not engaged specifically on whether WOE was a proper, or any kind of, scientific method, the Circuit treated the issue as virtually conceded:

Pfizer does not seem to contest the reliability of the Bradford Hill criteria or weight of the evidence analysis generally; the dispute centers on whether the specific methodology implemented by Dr. Jewell is reliable. Flexible methodologies, such as the “weight of the evidence,” can be implemented in multiple ways; despite the fact that the methodology is generally reliable, each application is distinct and should be analyzed for reliability.”

Zoloft at 18. The Court acknowledged that WOE arose only in the PSC’s appellate brief, which would have made the entire dubious argument waived under general appellate jurisdictional principles, but the Court, in a footnote, indulged the assumption, “for the sake of argument,” that WOE was Jewell’s purported method from the inception. Zoloft at 18 n. 39. Without any real evidentiary support or analysis or concession from Pfizer, the Circuit accepted that WOE analyses were “generally reliable.” Zoloft at 21.

The Circuit accepted, rather uncritically, that Jewell used a combination of WOE analysis and Bradford Hill considerations. Zoloft at 17. Although Jewell had never described WOE in his litigation report, and WOE was not a feature of his hearing testimony, the Circuit impermissibly engrafted Carl Cranor’s description of WOE as involving inference to the best explanation. Zoloft at 17 & n.37, citing Milward v. Acuity Specialty Prods. Grp., Inc., 639 F.3d 11, 17 (1st Cir. 2011) (internal quotation marks and citation omitted).

There was, however, a limit to the Circuit’s credulousness and empathy. As the Court noted, there must be some assurance that the purported Bradford Hill/WOE method is something more than a “mere conclusion-oriented selection process.” Zoloft at 20. Ultimately, the Court put its markers down for Jewell’s putative WOE methodology:

there must be a scientific method of weighting that is used and explained.”

Zoloft at 20. Calling the method WOE did not, in the final analysis, exclude Jewell from Rule 702 gatekeeping. Try as the PSC might, there was just no mistaking Jewell’s approach as anything other than a crazy patchwork quilt of numerical wizardry in aid of subjective, result-oriented conclusion mongering.

In the Court’s words:

we find that Dr. Jewell did not 1) reliably apply the ‘techniques’ to the body of evidence or 2) adequately explain how this analysis supports specified Bradford Hill criteria. Because ‘any step that renders the analysis unreliable under the Daubert factors renders the expert’s testimony inadmissible’, this is sufficient to show that the District Court did not abuse its discretion in excluding Dr. Jewell’s testimony.”

Zoloft at 28. As heartening as the Circuit’s conclusion is, the Court’s couching its observation as a finding (“we find”) is disheartening with respect to the Third Circuit’s apparent inability to distinguish abuse-of-discretion review from de novo appellate findings. Equally distressing is the Court’s invocation of Daubert factors, which were dicta in a Supreme Court case that was superseded by an amended statute over 17 years ago, in Federal Rule of Evidence 702.

On the crucial question whether Jewell had engaged in an unreliable application of methods or techniques that superficially, at a very high level of generality, claim to be generally accepted, the Court stayed on course. The Court “found” that Jewell had applied techniques, analyses, and critiques so obviously inconsistently that no amount of judicial indulgence, assumptions arguendo, or careless glosses could save Jewell and his fatuous opinions from judicial banishment. Zoloft 28-29. Returning to the correct standard of review (abuse of discretion), but the wrong governing law (Daubert instead of Rule 702), the Court announced that:

[b]ecause ‘any step that renders the analysis unreliable under the Daubert factors renders the expert’s testimony inadmissible’, this is sufficient to show that the District Court did not abuse its discretion in excluding Dr. Jewell’s testimony.”

Zoloft at 21 n.50 (citation omitted). The Court found itself unable to say simply and directly that “the MDL trial court decided the case well within its discretion.”

The Zoloft case was not the Third Circuit’s first WOE rodeo. WOE had raised its unruly head in Magistrini v. One Hour Martinizing Dry Cleaning, 180 F. Supp. 2d 584, 602 (D.N.J. 2002), aff’d, 68 F. App’x 356 (3d Cir. 2003), where an expert witness, David Ozonoff, offered what purported to be a WOE opinion. The Magistrini trial court did not fuss with the assertion that WOE was generally reliable, but took issue with how Ozonoff tried to pass off his analysis as a comprehensive treatment of the totality of the evidence. In Magistrini, Judge Hochberg noted that regardless of the rubric of the methodology, the witness must show that in conducting a WOE analysis:

all of the relevant evidence must be gathered, and the assessment or weighing of that evidence must not be arbitrary, but must itself be based on methods of science.”

Magistrini, 180 F. Supp. 2d at 602. The witness must show that the methodology is more than a “mere conclusion-oriented selection process,” and that it has a “a scientific method of weighting that is used and explained.” Id. at 607. Asserting the use of WOE was not an excuse or escape from judicial gatekeeping as specified by Rule 702.

Although the Third Circuit gave the Zoloft MDL trial court’s findings a searching review (certainly much tougher than the prescribed abuse-of-discretion review), the MDL court’s finding that Jewell “failed to consistently apply the scientific methods he articulates, has deviated from or downplayed certain well-established principles of his field, and has inconsistently applied methods and standards to the data so as to support his a priori opinion” were ultimately vindicated by the Court of Appeals. Zoloft at 10.

All’s well that ends well. Perhaps. It remains unfortunate, however, that a hypothetical method, WOE — which was never actually advocated by the challenged expert witnesses, which lacks serious support in the scientific community, and which was merely assumed arguendo to be valid — will be taken by careless readers to have been endorsed the Third Circuit.

Every Time a Bell Rings

July 1st, 2017

“Every time a bell rings, an angel gets his wings.”
Zuzu Bailey

And every time a court issues a non-citable opinion, a judge breaks fundamental law. Whether it wants to or not, a common law court, in deciding a case, creates precedent, and an expectation and a right that other, similarly situated litigants will be treated similarly. Deciding a case and prohibiting its citation deprives future litigants of due process and equal protection of the law. If that makes for more citable opinions, more work for judges and litigants, so be it; that is what our constitution requires.

Back in 2015, Judge Bernstein issued a ruling in a birth defects case in which the mother had claimed to have taken sertraline during pregnancy and this medication use caused her child to be born with congenital malformations. Applying what Pennsylvania courts insist is a Frye standard, Judge Bernstein excluded the proffered expert witness testimony that attempted to draw a causal connection between the plaintiff’s birth defect and the mother’s medication use. Porter v. SmithKline Beecham Corp., No. 03275, 2015 WL 5970639 (Phila. Cty. Pennsylvania, Ct. C.P. October 5, 2015) (Mark I. Bernstein, J.) Judge Bernstein has since left the bench, but he was and is a respected commentator on Pennsylvania evidence1, even if he was generally known for his pro-plaintiff views on many legal issues. Bernstein’s opinion in Porter was a capable demonstration of how Pennsylvania’s Frye rule can be interpreted to reach essentially the same outcome that is required by Federal Rule of Evidence 702. SeeDemonstration of Frye Gatekeeping in Pennsylvania Birth Defects Case” (Oct. 6, 2015); In re Zoloft Prod. Liab. Litig., No. 16-2247 , __ F.3d __, 2017 WL 2385279 , 2017 U.S. App. LEXIS 9832 (3d Cir. June 2, 2017) (affirming exclusion of dodgy statistical analyses and opinions, and the trial court’s entry of summary judgment on claims that sertraline causes birth defects).

In May of this year, the Pennsylvania Superior Court affirmed Judge Bernstein’s judgment, and essentially approved and adopted his reasoning. Porter v. SmithKline Beecham Corp., No. 3516 EDA 2015,2017 WL 1902905 (Pa. Super. May 8, 2017). What the Superior Court purport to giveth, the Superior Court taketh away. The Porter decision is franked as a “Non-Precedential Decision – See Superior Court I.O.P. 65.37.”

What is this Internal Operating Procedure that makes the Superior Court think that it can act and decide cases without creating precedent? Here is the relevant text from the Pennsylvania Code:

  1. An unpublished memorandum decision shall not be relied upon or cited by a Court or a party in any other action or proceeding, except that such a memorandum decision may be relied upon or cited
  1. when it is relevant under the doctrine of law of the case, res judicata, or collateral estoppel, and
  1. when the memorandum is relevant to a criminal action or proceeding because it recites issues raised and reasons for a decision affecting the same defendant in a prior action or proceeding.

210 Pa. Code § 65.37. Unpublished Memoranda Decisions. So, in other words, it is secret law.

No citation and no precedent rules are deeply problematic, and have attracted a great deal of scholarly attention2. And still, courts engage in this problematic practice. Prohibiting citation of Superior Court decisions in Pennsylvania is especially problematic in a state in which the highest court hears relatively few cases, and where the Justices involve themselves in internecine disputes. As other commentators have noted, prohibiting citation to prior decisions admitting or excluding expert witness testimony stunts the development of an area of evidence law, in which judges and litigants are often confused and in need of guidance. William E. Padgett, “‘Non-Precedential’ Unpublished Decisions in Daubert and Frye Cases, Often Silenced,” Nat’l L. Rev. (2017). The abuses of judge-made secret law from uncitable decisions has been abolished in the federal appeals courts for over a decade3. It is time for the state courts to follow suit.

The Slemp Case, Part I – Jury Verdict for Plaintiff – 10 Initial Observations

May 13th, 2017

While I greatly appreciate you informing me, on three separate occasions, that I am not under investigation, I nevertheless concur with the judgment of the Department of Justice that you are not able to effectively lead the Bureau.”

Letter from Donald Trump to James Comey (May 9, 2017) (emphasis added)

Just as a President’s poor diction does not define or guide good English grammar, a lay civil jury’s verdict on scientific issues does not resolve open scientific questions of causation between exogenous exposures and cancer or other chronic disease outcomes. Last week, a jury in St. Louis returned a substantial verdict for compensatory and punitive damages against Johnson & Johnson, and others, for supposedly causing Lois Slemp to develop ovarian cancer. From some of the media coverage, readers might infer that Ms. Slemp’s attorneys’ had presented a credible case of causation between perineal talc use and ovarian cancer. See, e.g., Daniel Siegal, “J&J Hit With $110M Verdict In Latest Mo. Talc Cancer Trial,” Law360 (May 4, 2017). The cause of this verdict requires close scrutiny of the scientific evidence, the jury and juries generally, the lawyering from both sides, and the judicial management of the trial. 

Hit.” Hit? When did comic-book language invade legal journalism? Why not “slammed,” “zapped,” or “kapow”?

The case, which has gained this recent notoriety is Lois Slemp v. Johnson & Johnson, case no. 1422-CC09326-01, 22nd Judicial Circuit Court of Missouri. The jury awarded Ms. Slemp $5.4 million in compensation, and $66 million against Johnson & Johnson, $39 million against Johnson & Johnson Consumer, and $50,000 against Imerys (the talc miner and supplier), in punitive damages. On the compensatory award, the jury ascribed 99 percent of fault to the two J & J companies, and 1 percent to Imerys. Id.

The truth is that the Slemp verdict, as is the case for most civil jury verdicts, does not represent a valid scientific judgment. Nonetheless, the verdict requires explanation. If talc does not cause ovarian cancer, we may well ask whether the case was poorly defended, whether the court system failed to serve as a gatekeeper, and whether the scientific case was beyond the comprehension of the lay jury.

The verdict of course also raises serious questions about our civil justice system. The law of products liability typically states that a manufacturer or seller is held to the level of an expert in knowing the harmful aspects of its products. If this knowledge is widely known about consumers, then the seller will generally have an obligation to warn about the latent harm. But what happens when there is no knowledge of a causal relationship? Or what happens when experts legitimately disagree? How can a manufacturer or seller be charged with outrageous misconduct, let alone negligence, when experts sincerely and legitimately disavow a causal relationship?

David H. Schwartz, Ph.D. of Innovative Science Solutions LLC, and I posted a preliminary, big-picture overview of the Slemp case at the Courtroom View Network’s website. See Schwartz & Schachtman, “10 Key Scientific Takeaways From Recent $110M Talc Powder Verdict,” Courtroom View Network Blog (May 12, 2017). Thanks to the generosity of Courtroom View, David and I were able to view the video of the Slemp trial, and to evaluate the legal process of presenting a complicated scientific case to a lay jury. There is much to be said about that process, what went right and what went wrong, but for now, I will simply repeat, below, what we said on CVN’s blog. I hope in subsequent posts to look more closely at specific issues, especially with respect to the presentation of statistical and epidemiologic evidence, by all parties.

* * * * *

The following is a republication (with minor formatting changes) of the original post, by David H. Schwartz and Nathan Schachtman. 

Establishing a rigorous and reliable causal inference between an exposure and an adverse health outcome is one of the most difficult things to do in the health sciences. However, it is sometimes even more difficult to effectively and appropriately demonstrate that a causal relationship does not exist.

The difficulty of this task was illustrated in the most recent talcum powder trial in St. Louis, Missouri. As was widely reported, Johnson & Johnson and talc raw material producer Imerys received the third (and largest) plaintiff verdict in their four recent talc trials (3 plaintiff verdicts and one defense verdict). Having the enviable opportunity to watch the trial (in real time or on demand) on Courtroom View Network’s website provides an invaluable opportunity to review and learn from an important ongoing mass tort action.

At this trial, the defense put up a single expert witness, Dr. Huh, a clinician who defended the aggressive and wide-ranging scientific claims advanced by plaintiff’s expert witnesses in a number of scientific disciplines, including epidemiology, clinical medicine, and pathology. Dr. Huh, a skilled and experienced ObGyn and a clinical gynecological oncologist, attempted to neutralize plaintiff’s scientific allegations made by putting the clinical characteristics of the patient into context, while dismissing the many statistically significant epidemiological studies touted by plaintiffs as adequately establishing a causal inference for talcum powder and ovarian cancer.

In his cross examination, plaintiff counsel continuously barraged Dr. Huh with technical observations relating to the large body of epidemiologic studies that plaintiff expert witnesses claimed demonstrated that talc exposure caused ovarian cancer. From the perspective of a scientist who has consulted with many product manufacturers alleged to cause cancer and other chronic diseases, and a lawyer who has tried many science-based cases over the past 32 years, this most recent trial illustrates some important and emblematic issues that arise in pharmaceutical, medical device, and toxic tort cases. We provide 10 such observations below.

1. Provide overall context of Bradford Hill criteria

Unlike other legal cases where there is a paucity of epidemiologic data showing statistically significant associations between an exposure and a disease endpoint, in this case there are many epidemiologic studies – and even some meta-analyses – that invite plaintiffs to make the claim that the available scientific evidence meets the Bradford Hill criteria. Therefore, it is critical to provide the jury with a lucid understanding of why the Bradford Hill criteria are utilized and how they should appropriately be applied. Indeed, the Bradford Hill criteria were developed for a situation exactly like the talc litigation; that is, a relatively weak association is reported and scientists want to determine whether that association should validly and reliably be considered causal.

2. Build solid foundation for “correlation does not equal causation” argument

Multiple studies assert an association between talc and ovarian cancer. However, the defense position is that the studies used to make this assertion suffer from bias and confounding, making them unreliable. Relying upon multiple flawed or biased studies to demonstrate a relationship between two factors does not make the two factors causally related. For example, it does not matter how many times one shows that wearing work boots is associated with back injury, it does not make wearing work boots a cause of back injury. (The two factors are associated, but not causally so.) It is critical for the defense to make it crystal clear (as many times as he is questioned) that “correlation does not equal causation.”

3. Develop a genetic defense

Knowledge of the role of genetic data related to ovarian cancer is moving at breakneck speed. Indeed, a study was published in March identifying nine new susceptibility loci for different epithelial ovarian cancer histotypes. While these data may or may not have been relevant to the individual patient in the Slemp trial, there is no way to know unless the defense had a full genome sequence of the plaintiff’s germline. Such information could conceivably be aligned with newly published data to demonstrate that her genetic profile was consistent with the development of ovarian cancer.

4. Hone the lack of consistency argument

Not surprisingly, in his cross examination of Dr. Huh, plaintiff counsel repeatedly referred to the many case-control studies that reported statistically significant associations between talc and ovarian cancer to support the view that the Hill criterion of “consistency” was met. Dr. Huh repeatedly attempted to rebut this assertion, but failed to make a clear argument as to why these multiple studies failed to support the criterion of consistency. He did refer to the fact that the cohort studies disagreed with the case control studies, but failed to clearly articulate his interpretation of that discrepancy.

At the end of the day, it is not at all surprising that multiple confounded and biased studies all demonstrate the same association. To truly demonstrate the criterion of consistency, one must show that the same results are obtained when using different study methods. Indeed, when a different study design is utilized (cohort studies), the association vanishes. One can posit methodological flaws in the cohort studies (misclassification bias as was repeatedly stated by plaintiff counsel), but flaws can also be posited for the case control studies (recall bias and confounding). The point is that repeating the same poorly conceived study design over and over does not constitute consistency and that the criterion of consistency is therefore not met in this data set.

An example, such as the strong relationship between Vitamin A and cancer prevention might have helped. In observational studies, Vitamin A is clearly associated with a reduction of lung cancer rates based on multiple observational studies. When the claim was tested in randomized clinical trials, the claim failed miserably; indeed, Vitamin A might even increase the rate of lung malignancies in those who took supplements. Similarly, hormone replacement therapy (HRT) was once thought to decrease the risk of cardiovascular disease based on multiple observational studies. It was not until a large randomized controlled trial was conducted that the putative association between HRT and cardiovascular benefit was discredited.

5. Do not let conflict of interest arguments cloud the causal inference assessment

Alleged conflicts of interest were raised repeatedly in accusatory tones, suggesting that any research that J & J funded could not be trusted. Furthermore, suggestions were made that J & J controlled where funding was allocated through their contributions to the National Institutes of Health. These arguments must be addressed aggressively and should not be allowed to hang in the air without response.

6. Pathological evidence must be confronted by someone who studied the pathology slides

Plaintiff counsel confronted Dr. Huh with allegations by plaintiff’s pathologist about the type of cancer from which plaintiff suffered. Because Dr. Huh is not a pathologist and because he did not look at plaintiff’s pathology sides, he attempted to use his clinical impressions and medical records to counter the pathological evidence offered by the plaintiff’s expert witness in pathology. The defense seemed enamored of a “less is more” strategy, but forcing expert witnesses into testimony beyond their expertise requires fortitude and perhaps luck.

7. Put “authoritative”statements into appropriate context

Throughout his cross examination, plaintiff’s counsel confronted Dr. Huh with statements from web sites and textbooks suggesting that talc caused ovarian cancer or where talc is listed as a risk factor for ovarian cancer. Many times, such statements referred to a putative association as opposed to a causal relationship. It is critical to point out their inherent weaknesses, including the fact that they have been cherry picked and to counter with other authoritative sources where talc is not listed as a risk factor and/or the causal link has been questioned. It is also important to be ready with other risk factors that could be equally likely to be linked to ovarian cancer and to emphasize that focusing on talc is arbitrary. The plaintiff is this recent trial was morbidly obese, an undisputed risk factor for ovarian cancer.

As with the lack of consistency argument (#3, above), rebuttal of this contention would be effectively guided using specific examples. For instance, many textbooks and other authoritative sources stated that HRT had cardiovascular benefits based on multiple observational studies. The fact is that these statements were wrong.

8. Concede that cohort studies are not always better than case-control studies

The talc defense strongly asserted the view that cohort studies are necessarily better than case control studies. While this contention is generally true (all factors being equal), it is not always true and it leads to some effective cross examination (e.g., the general assertion that cohort studies may suffer, in some instances, from misclassification bias). As one of us (NAS) stated in a recent post related to the California Science Day hearings, there is no reason to make the blanket statement that cohort studies are always better than case control studies.

Rather, the general point can be made that each study type has its appropriate use and that in this case, the findings from studies using the two different methodologies do not agree with each other. Clearly, the role of differential recall is just as likely to bias a case control study as the role of misclassification is to bias a cohort study. This leaves the evidence at a draw at best.

9. Provide a multi-disciplinary defense

In a case involving so many complex disciplines, it does not seem tenable to address all of them with a single expert, even one as well qualified and experienced as Dr. Huh. Many defense lawyers firmly believe in the “less is more” strategy, but complex scientific data sets such as these necessitate a complete presentation of the exculpatory evidence. Although it is easy in hindsight to criticize trial strategy, forcing a clinical oncologist to address pathology, toxicology, and epidemiology places an unfair burden on the lone witness. Certainly, a jury may be more prone to view an expert witness, who is willing to testify outside his area of expertise, as a hired gun advocate.

10. Careful and consistent use of terminology

Because of the nuanced nature of the defense case (i.e., statistically significant associations demonstrated in observational studies may not be causal in nature), it is critical to use terms consistently and carefully. Terms such as “association,” “link,” “causal inference,” and “causation” must be carefully defined and utilized judiciously and with clear intent.

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

Of course, looking at testimony in hind-sight is always 20/20. As stated at the outset of this piece defending the assertion that an exposure is not causally related to a clearly defined injury is one of the most difficult things to do in the courtroom, especially when this is attempted through a single expert witness and there are numerous studies purporting to make such a link. Nevertheless, some extremely critical lessons can be learned from this experience to guide future cases.

David Egilman and Friends Circle the Wagons at the International Journal of Occupational & Environmental Health

May 4th, 2017

Andrew Maier is an associate professor in the Department of Environmental Health, in the University of Cincinnati. Maier received his Ph.D. degree in toxicology, with a master’s degree in industrial health. He is a Certified Industrial Hygienest and has published widely on occupational health issues. Earlier this year, Maier was named the editor-in-chief of the International Journal of Occupational and Environmental Health (IJOEH). See Casey Allen, “Andy Maier Named Editor of Environmental Health Journal(Jan. 18, 2017).

Before Maier’s appointment, the IJOEH was, for the last several years, the vanity press for former editor-in-chief David Egilman and “The Lobby,” the expert witness brigade of the lawsuit industry. Egilman’s replacement with Andrew Maier apparently took place after the IJOEH was acquired by the scientific publishing company Taylor & Francis, from the former publisher, Maney.

The new owner, however, left the former IJOEH editorial board, largely a gaggle of Egilman friends and fellow travelers in place. Last week, the editorial board revoltingly wrote [contact information redacted] to Roger Horton, Chief Executive Officer of Taylor & Francis, to request that Egilman be restored to power, or that the current Editorial Board be empowered to choose Egilman’s successor. With Trump-like disdain for evidence, the Board characterized the new Editor as a “corporate consultant.” If Maier has consulted with corporations, his work appears to have rarely if ever landed him in a courtroom at the request of a corporate defendant. And with knickers tightly knotted, the Board also made several other demands for control over Board membership and journal content.

Andrew Watterson wrote to Horton on behalf of all current and former IJOEH Editorial Board members, a group heavily populated by plaintiffs’ litigation expert witnesses and “political” scientists, including among others:

Arthur Frank

Morris Greenberg

Barry S. Levy

David Madigan

Jock McCulloch

David Wegman

Barry Castleman

Peter Infante

Ron Melnick

Daniel Teitelbaum

None of the signatories apparently disclosed their affiliations as corporate consultants for the lawsuit industry.

Removing Egilman from control was bad enough, but the coup de grâce for the Lobby came earlier in April 2016, when Taylor & Francis notified Egilman that a paper that he had published in IJOEH was being withdrawn. According to the petitioners, the paper, “The production of corporate research to manufacture doubt about the health hazards of products: an overview of the Exponent Bakelite simulation study,” was removed without explanation. See Public health journal’s editorial board tells publisher they have ‘grave concerns’ over new editor,” Retraction Watch (April 27, 2017).

According to Taylor & Francis, the Egilman article was “published inadvertently, before the review process had been completed. On completing that review, it was decided the article was unsuitable for publication in the journal.” Id. Well, of course, Egilman’s article was unlikely to receive much analytical scrutiny at a journal where he was Editor-in-Chief, and where the Board was populated by his buddies. The same could be said for many articles published under Egilman’s tenure at the IJOEH. Taylor & Francis owes Egilman and the scientific and legal community a detailed statement of what was in the article, which was “unsuitable,” and why. Certainly, the law department at Taylor & Francis should make sure that it does not give Egilman and his former Board of Editors grounds for litigation. They are, after all, tight with the lawsuit industry. More important, Taylor & Francis owes Dr. Egilman, as well as the scientific and legal community, a full explanation of why the article in question was unsuitable for publication in the IJOEH.

New York Rejects the Asbestos Substantial Factor Ruse (Juni Case)

March 2nd, 2017

I recall encountering Dr. Joseph Sokolowski in one of my first asbestos personal injury cases, 32 years ago. Dr. Sokolowki was a pulmonary specialist in Cherry Hill, New Jersey, and he showed up for plaintiffs in cases in south Jersey as well as in Philadelphia. Plaintiffs’ counsel sought him out for his calm and unflappable demeanor, stentorious voice, and propensity for over-interpreting chest radiographs. (Dr. Sokolowski failed the NIOSH B-Reader examination.)

At the end of his direct examination, the plaintiff’s lawyer asked Dr. Sokolowski the derigueur “substantial factor” question, which in 1985 had already become a customary feature of such testimonies. And Dr. Sokolowski delivered his well-rehearsed answer: “Each and every exposure to asbestos was a substantial factor in causing the plaintiff’s disease.”

My cross-examination picked at the cliché. Some asbestos inhaled was then exhaled. Yes. Some asbestos inhaled was brought up and swallowed. Yes. Asbestos that was inhaled and retained near the hilum did not participate in causing disease at the periphery of the lung. Yes. And so on, and so forth. I finished with my rhetorical question, always a dangerous move, “So you have no way to say that each and every exposure to asbestos actually participated in causing the plaintiff’s disease?” Dr. Sokolowski was imperceptibly thrown off his game, but he confessed error by claiming the necessity to cover up the gap in the evidence. “Well, we have no way to distinguish among the exposures so we have to say all were involved.”

Huh? What did he say? Move to strike the witness’s testimony as irrational, and incoherent. How can a litigant affirmatively support a claim by asserting his ignorance of the necessary foundational facts? The trial judge overruled my motion with alacrity, and the parties continued with the passion play called asbestos litigation. The judge was perhaps simply eager to get on with his docket of thousands of asbestos cases, but at least Dr. Sokolowski and I recognized that the “substantial factor” testimony was empty rhetoric, with no scientific or medical basis.

Sadly, the “substantial factor” falsehood was already well ensconced in 1985, in Pennsylvania law, as well as the law of most other states. Now, 32 years later, with ever increasingly more peripheral defendants, each involving less significant, if any, asbestos exposure, the “substantial factor” ruse is beginning to unravel.1

Juni v. A.O. Smith Water Products Co.

Arthur Juni was a truck and car car mechanic, who worked on the clutches, brakes, and manifold gaskets of Ford trucks. Juni claimed to have sustained asbestos exposure in this work, as well as in other aspects of his work career. In 2012, Juni was diagnosed with mesothelioma; he died in 2014. Juni v. A.O. Smith Water Products Co., at *1,No. 190315/12 2458 2457, 2017 N.Y. Slip Op. 01523 (N.Y. App. Div. 1st Dep’t, Feb. 28, 2017).

Juni sued multiple defendants in New York Supreme Court, for New York County. Most of the defendants settled, but Ford Corporation tried the case against the plaintiff’s widow. Both sides called multiple expert witnesses, whose testimony disputed whether the chrysotile asbestos in Ford’s brakes and clutches could cause mesothelioma. The jury returned a verdict in favor of the plaintiff, but the trial court granted judgment nothwithstanding the verdict, on the ground that the evidence failed to support the causation verdict. Id. At *1; see Juni v. A. 0. Smith Water Prod., 48 Misc. 3d 460, 11 N.Y.S.3d 415 (N.Y. Sup. Ct. 2015).

Earlier this week, the first department of the New York Appellate Division affirmed the judgment for Ford. 2017 N.Y. Slip Op. 01523. The Appellate Division refused to approve plaintiffs’ theory of cumulative exposure to show causation. The plaintiffs’ expert witnesses, Drs. Jacqueline Moline and Stephen Markowitz, both asserted that even a single asbestos exposure was a “substantial contributing” cause. The New York appellate court, like the trial court before, saw through the ruse, and declared that both expert witnesses had failed to support their assertions.

The “Asbestos Exception” Rejected

Although New York has never enacted a codified set of evidence rules, and has never expressly adopted the rule of Daubert v. Merrill Richardson, the New York Court of Appeals has held that there are limits to the admissibility of expert witness opinion testimony. Parker v. Mobil Oil Corp., 7 N.Y.3d 434 (2006), and Cornell v. 360 W. 51st St. Realty, LLC, 22 NY3d 762 (2014); Sean Reeps. v BMW of North Am., LLC, 26 N.Y.3d 801 (2016). In Juni, the Appellate Division, First Department, firmly rejected any suggestion that plaintiffs’ expert witnesses in asbestos cases are privileged against challenge over admissibility or sufficiency because the challenges occur in an asbestos case. The plaintiff’s special pleading that asbestos causation of mesothelioma is too difficult was invalidated by the success of other plaintiffs, in other cases, in showing that a specific occupational exposure was sufficient to cause mesothelioma.

The Appellate Division also rejected the plaintiff’s claim, echoed in the dissenting opinion of one lone judge, that there exists a “consensus from the medical and scientific communities that even low doses of asbestos exposure, above that in the ambient environment, are sufficient to cause mesothelioma.” The Court held that this supposed consensus is not material to the claims of a particular plaintiff against a particular defendant, especially when the particular exposure circumstance is not associated with mesothelioma in most of the relevant studies. In Juni, the defense had presented many studies that failed to show any association between occupational brake work and mesothelioma. The court might also have added that a characterization of low exposure is extremely amiguous, depending upon the implicit comparison that is being made with other exposures. It is impossible to fit a particular plaintiff’s exposure into the scale of low, medium, and high without some further context.

Single Exposure Sufficiency Rejected

The evidence that chrysotile itself causes mesothelioma remains weak, but the outcome of Juni turned not on the broad general causation question, but on the question whether even suggestive evidence of chrysotile causation had been established for the exposure circumstances of an automobile mechanic, such as Mr. Juni. Plaintiffs’ expert witnesses maintained that Juni’s cumulative asbestos exposures caused his mesothelioma, but they had no meaningful quantification or even reasonable estimate of his exposure.

Citing the Court of Appeals decision in Reeps, the Appellate Division held that plaintiff’s expert witnesses’ causation opinions must be supported by reasonable quantification of the plaintiff’s exposure, or some some scientific method, such as mathematical modeling based upon actual work history, or by comparison of plaintiff’s claimed exposure with the exposure of workers in reported studies that establish a relevant risk from those workers’ exposure. In the Juni case, however, there were no exposure measurements or scientific models, and the comparison with workers doing similar tasks failed to show a causal relationship between the asbestos exposure in those tasks and mesothelioma.

Expert Witness Admissibility and Sufficiency Requires Evaluation of Both Direct and Cross-examination Testimony and Relied Upon Studies

The Juni decision teaches another important lesson for challenging expert witness testimony in New York: glib generalizations delivered on direct examination must be considered in the light of admissions and concessions made on cross-examination, and the entire record. In Juni, the plaintiffs’ expert witnesses, Jacqueline Moline and Stephen Markowitz, asserted that asbestos in Ford’s friction products was a cause of plaintiff’s mesothelioma. Cross-examination, however, revealed that these assertions were lacking in factual support.

Cumulative Exposure

On cross-examination, the plaintiffs’ expert witnesses’ statements about exposure levels proved meaningless. Moline attempted to equate visible dust with sufficient asbestos exposure to cause disease, but she conceded on cross-examination that studies had shown that 99% of brake lining debris was not asbestos. Most of the dust observed from brake drums is composed of resins used to manufacture brake linings and pads. The heat and pressure of the brake drum causes much of the remaining chrysotile to transform into a non-fibrous mineral, fosterite.

Similarly, Markowitz had to acknowledge that chrysotile has a “serpentine” structure, with individual fibers curling in a way that makes deeper penetration into the lungs more difficult. Furthermore, chrysotile, a hydrated magnesium silicate, melts in the lungs, not in the hands. The human lung can clear particulates, and so there is no certainty that remaining chrysotile fibers from brake lining exposures ever reach the periphery of the lung, where they could interact with the pleura, the tissue in which mesothelioma arises.

Increased Risk, “Linking,” and Association Are Not Causation – Exculpatory Epidemiologic Studies

When pressed, plaintiffs’ expert witnesses lapsed into characterizing the epidemiologic studies of brake and automobile mechanics as showing increased risk or association, not causation. Causation, not association, however, was the issue. Witnesses’ invocation of weasel words, such as “increased risk,” “linkage,” and “association” are insufficient in themselves to show the requisite causation in long-latency toxic exposure cases. For automobile mechanics, even the claimed association was weak at best, with plaintiffs’ expert witnesses having to acknowledge that 21 of 22 epidemiologic studies failed to show an association between automobile mechanics’ asbestos exposure and risk of mesothelioma.

The Juni case was readily distinguishable from other cases in which the Markowitz was able to identify epidemiologic studies that showed that visible dust from a specific product contained sufficient respirable asbestos to cause mesothelioma. Id. (citing Caruolo v John Crane, Inc., 226 F.3d 46 (2d Cir. 2000). As the Appellate Division put the matter, there was no “no valid line of reasoning or permissible inference which could have led the jury to reach its result.” Asbestos plaintiffs must satisfy the standards set out in the New York Court of Appeals decisions, Parker v. Mobil Oil Corp., 7 NY3d 434 2006), and Cornell v. 360 W. 51st St. Realty, LLC, 22 N.Y.3d 762 (2014), for exposure evidence and causal inferences, as well.

New York now joins other discerning courts in rejecting regulatory rationales of “no safe exposure,” and default “linear no threshold” exposure-response models as substitutes for inferring specific causation.2 A foolish consistency may be the hobgoblin of little minds, but in jurisprudence, consistency is often the bedrock for the rule of law.


1 The ruse of passing off “no known safe exposure” as evidence that even the lowest exposure was unsafe has been going on for a long time, but not all judges are snookered by this rhetorical sleight of hand. See, e.g., Bostic v. Georgia-Pacific Corp., 439 S.W.3d 332, 358 (Tex. 2014) (“the failure of science to isolate a safe level of exposure does not prove specific causation”).

2 See, e.g. Bostic v. Georgia-Pacific Corp., 439 S.W.3d 332, 358 (Tex. 2014) (failing to identify safe levels of exposure does not suffice to show specific causation); Henricksen v. ConocoPhillips Co., 605 F. Supp. 2d 1142, 1165-66 (E.D. Wash. 2009) (rejecting a “no threshold” model of exposure-response as unfalsifiable and unvalidated, and immaterial to the causation claims); Pluck v. BP Oil Pipeline Co., 640 F.3d 671, 679 (6th Cir. 2011) (rejecting claim that plaintiff’s exposure to benzene “above background level,” but below EPA’s maximum permissible contaminant level, caused her cancer); Newkirk v. ConAgra Foods, Inc., 727 F. Supp. 2d 10006, 1015 (E.D. Wash. 2010) (rejecting Dr. David Egilman’s proffered testimony on specific causation based upon his assertion that there was no known safe level of diacetyl exposure).

Talc Litigation in Missouri – Show Me the Law and the Evidence

February 22nd, 2017

In New Jersey, where the courts are particularly plaintiff friendly but not beyond the persuasive force of evidence, lawsuit industry claims that talc causes ovarian cancer have not fared well. Last year, Judge Johnson, of Atlantic County, New Jersey, held that the plaintiffs’ causal claims failed to meet even the minimal New Jersey legal threshold of scientific validity.1 Meanwhile, in Missouri, juries have been returning large verdicts for plaintiffs on their claims that their use of talc products caused their ovarian cancers.2

What gives? Why is the outcome of similar litigation so different in New Jersey from that in Missouri? One might mistakenly think that courts in Missouri would be skeptical of scientifically dubious claims. After all, Missouri is the “Show Me” state; right? Many people understand the state’s nickname to mean that Missourians are not gullible.3

The reality of the origins of the Missouri nickname may well be different. The most cited account reports that a congressman from Missouri, Willard Duncan Vandiver, used the phrase in an 1899 speech:

I come from a state that raises corn and cotton and cockleburs and Democrats, and frothy eloquence neither convinces nor satisfies me. I am from Missouri. You have got to show me.”

Basically, according to Vandiver, Missourians are “show me” simple folks because they do not read or understand eloquent language. Vandiver might have thought that scientific language was beyond his neighbors’ ken as well. Of course, things have changed since 1899. Missouri is no longer a state populated by Democrats. In the 2016 general election, Donald Drumpf received 56.8% of the Missouri votes cast. Hilary Clinton received 38.1%.4  Inquiring minds will want to know whether “Show Me” connotes incredulity or illiteracy.

One relevant difference between Missouri and many other states, and all the federal courts, is that some courts in Missouri engage in a particularly edentulous form of judicial gatekeeping of expert witness opinion testimony. The talc claims that resulted in large verdicts in Missouri never got off the dime (or got a dime) in New Jersey because plaintiffs’ expert witnesses’ opinions were excluded from courtrooms in the Garden State.

The resulting trials in Missouri have showcased some curious, doubtful rhetoric from legal counsel for the lawsuit industry. In his closing argument in Giannecchini v. Johnson & Johnson, the plaintiff’s lawyer accused Johnson & Johnson of having “rigged” regulatory agencies to ignore the dangers of talc.5 The argument was apparently effective and it has been repeated in another Missouri trial, in Swann v. Johnson & Johnson6, now underway. The plaintiffs’ opening “statement” in Swann was marked by overwrought, hyperbolic rhetoric.7

And the first trial days in Swann were dedicated by plaintiff’s counsel to showing, not that talc actually causes ovarian cancer, but to showing that the defendants engaged in lobbying with respect to the carcinogenic classification of talc by regulatory agencies.8 According to the coverage in legal news media, the first testimony offered was offered to show that after the National Toxicology Program (NTP) nominated talc for inclusion in its list of potential carcinogens, industry trade groups, such as the Cosmetic, Toiletry and Fragrance Association, “shut down serious regulator concerns through intensive lobbying efforts.”9

This is a remarkable digression from the truth finding function of an American jury trial for several reasons. First, the “shutting down” of regulator concern was not, in the media reports, associated with any fraudulent misrepresentations of the scientific record. By casting the lobbying in an unflattering light, the plaintiff was able to undermine the truth value of agencies’ refusal to characterize talc as an ovarian carcinogen. The media coverage did not suggest that the lobbying involved the presentation of sham evidence or arguments that might have misled agencies about the correctness of their position.

Second, if the industry lobbying had badly misled the National Toxicology Program, or other government body, then there would no doubt be a conclusive case for causation today. The fact of the matter, however, is that there is no conclusive case for the claim that talc causes ovarian cancer. Late last year, the “Sister Study,” which explored whether there was any association between perineal talc use and ovarian cancer, was published in Epidemiology.10 The Sister Study (2003–2009) followed a cohort of 50,884 women whose sisters had been diagnosed with breast cancer. Talc use was ascertained at baseline, before diagnosis of subsequent disease and before any chance for selective recall. The cohort was followed for a median of 6.6 years, in which time there were 154 cases of ovarian cancer, available for analysis using Cox’s proportional hazards model. Perineal talc use at baseline was not associated with later ovarian cancer. The authors reported a hazard ratio of 0.73, less than expected, with a 95% confidence interval of 0.44, 1.2. Such a powerful study, showing the absence of any large or even modest association, would hardly be feasible if the science were so clear in the year 2000 that no reasonable scientist would have advocated against the NTP’s proposed classification.

Third, the lawsuit industry’s focus on lobbying activities in the Giannecchini and the Swann cases raises serious issues of infringing upon the defendants’ first amendment rights. The defendants’ advocacy for non-sham, non-fraudulent scientific positions is protected by the federal constitution, under what has come to be known as the Noerr-Pennington doctrine.

The Noerr-Pennington Doctrine of Immunity

One of the first agenda items for the first United States Congress was the drafting of a “Bill of Rights” to be submitted to the individual States for ratification. The First amendment (originally the third until the first two were dropped) sets forth a basic “right of the people to peaceably assemble, and to petition the government for a redress of grievances.”11 In the context of lobbying legislatures and regulatory agencies, the Supreme Court has long regarded lobbying and advocacy for and against legislation and regulation as core political speech that is protected by the right to petition the government.12

Part of this constitutional guarantee is a freedom to associate with others to lobby for redress.13 The constitutional protection is not lost by an economic or self-interested motivation in the lobbying or advocacy.14  This constitutional protection of advocacy positions results in an immunity from civil liability for speech, association, and conduct undertaken to advance advocacy positions before legislatures, agencies, and courts.15 This immunity, over half a century old, has come to be known as the Noerr-Pennington doctrine.

Although the original Noerr-Pennington doctrine cases specifically addressed claims of antitrust liability, later cases have held that the immunity applies with equal force in tort cases. State courts, regardless of their state constitutions, are of course obliged to grant and protect the federal Noerr-Pennington immunity.16

The unconstitutional infringement of defendants’ first amendment rights is hardly an innovation in Giannecchini and Swann cases. For decades, the lawsuit industry, which jealously guards its own first amendment rights, has overzealously pressed conspiracy and tort claims against manufacturing industry for trying to influence legislation and regulation. In Senart v. Mobay Chem. Corp., 597 F. Supp. 502 (D. Minn. 1984), plaintiffs alleged that they were harmed by exposure to toluene diisocyanate (TDI), a feedstock chemical used in making polyurethane foam. The plaintiffs sued TDI manufacturers, on conspiracy claims that the manufacturers had jointly influenced the Occupational and Safety Health Administration (OSHA) to reject a recommendation from the National Institute for Occupational Safety and Health (NIOSH) for lower permissible exposure standards for TDI. Senart, 597 F. Supp. at 504. The plaintiffs’ conspiracy complaint was based upon allegations that the manufacturing defendants knew of a body of scientific evidence which suggested that workers could suffer harm at exposure levels below the prevailing … standard,” and and that they “conspired to ‘obfuscate and confuse’ scientific findings which supported a more stringent standard.” Id. Plaintiffs also alleged that the TDI manufacturers knew that a more stringent TDI exposure standard would harm their businesses. Id.

The trial court dismissed the conspiracy count in Senart. “[E]ven accepting plaintiffs’ allegations as true, defendants concerted action sought only permissible ends and acted through permissible means.” Id. at 505-6 (footnote omitted). The defendants work in concert through their trade association to persuade OSHA to reject the NIOSH proposal was clearly protected by the first amendment. Id. at 506 (internal citations omitted).

Following Senart, federal courts in later products cases have applied he Noerr-Pennington doctrine to bar tort claims. In a 1996 class action, a district court held that the immunity barred a class action filed by relatives of gunshot victims against gun manufacturers. Hamilton v. ACCU-TEK 935 F. Supp. 1307 (E.D.N.Y. 1996). The court, in Hamilton, found the plaintiffs’ negligence and product liability claims untenable:

Defendants’ efforts to affect federal firearm policies through lobbying activities are prime examples of the types of activity the First Amendment, through its rights of free speech and petition, sought to protect… . A core principle of the Noerr-Pennington doctrine is that lobbying alone cannot form the basis of liability… .”

Id. at 1321. The court in Hamilton dismissed the product liability claims. See also Tuosto v. Philip Morris USA Inc., No. 05 Civ. 9384 (PKL), 2007 WL 2398507, at *5 (S.D.N.Y. Aug. 21, 2007) (noting that the immunity “applied to bar liability in state common law tort claims, including negligence and products liability claims, for statements made in the course of petitioning the government”).

The lawsuit industry is one of the largest rent-seeking groups in the United States. Our courts need to apply constitutional standards in a symmetrical fashion, with an understanding that what is spoken in the halls of legislatures and agencies is protected at least as much as speech in the courtroom, and that the constitutional rights of manufacturing industry should not be subordinated to the rights of the lawsuit industry. Maybe lawyers need to figure out how to “show” the constitution in pictograms, without all the 18th century eloquence.
