    Court excluded the testimony of Civil Engineering Expert Witness citing lack of baseline qualifications and unsupported alternative design theory

    Plaintiff Jorge Martins brought a products liability action against Defendants, The Sherwin-Williams Company (Sherwin-Williams) and Anixter Inc.The Plaintiff, a welder and mechanic employed at a power plant, suffered significant injuries, including the loss of his right eye, when a can of aerosol spray-paint primer exploded in his face while he was painting a fabricated steel piece. The Plaintiff initiated legal proceedings against Sherwin-Williams, the paint can manufacturer, and Anixter, Inc., the distributor, asserting claims of strict products liability, negligence, and breach of implied warranty. The Plaintiff contended that the paint can was defectively designed or manufactured and lacked adequate warnings. In response, Sherwin-Williams argued that the Plaintiff had mistreated the can by striking it against a table.

    The Plaintiff engaged Dale Cagwin as an expert engineer to provide insights on both design defect and failure-to-warn aspects of the case. Cagwin advanced the “failure-by-shaking” theory, asserting that the can’s dangerous and unreasonable design, characterized by a necked-in design and the use of double-reduced steel, led to its failure when shaken, ultimately causing the Plaintiff’s injury. According to Cagwin, the can’s design, considering the can’s circumference gradually narrows prior to its connection to the top and bottom portions of the can, increased its vulnerability to explosion during shaking, resulting in the harm suffered by the Plaintiff. Cagwin supported his opinion by referencing a 2011 report by Michael Fox (the “Fox report”), which concluded that cans made of single-reduced steel exhibited greater resistance to rupturing when dropped compared to those made of double-reduced steel.

    Furthermore, Cagwin expressed the opinion that the warning label on the paint can was inadequate and failed to prevent the Plaintiff’s injury. According to him, the deficient warning label rendered the can defective and unreasonably dangerous, constituting an additional factor contributing to the Plaintiff’s injuries. 

    Defendants moved to exclude Cagwin’s testimony on the grounds that he was unqualified and his opinions were unreliable. 

    Civil Engineering Expert Witness

    Dale J. Cagwin holds an Associate of Applied Science degree in Civil Engineering from Mohawk Valley Community College. Cagwin specializes in areas such as fire protection engineering, heating, ventilation, and air conditioning (“HVAC systems”), plumbing systems, wastewater treatment, compressed air systems, and industrial process systems. Cagwin is currently an Associate at Robson Forensic, Inc. and Fournier Robson & Associates, LLC. In this role, he provides investigations, analysis, reports, and testimony regarding failures and accidents involving mechanical systems and products. He also works to technically assist contractors and owners related to HVAC, plumbing, water treatment, and wastewater treatment systems.

    Discussions by the Court

    The Defendants contended that Cagwin lacked the qualifications to offer opinions on the issues outlined in his report. They argued that his academic and professional background, with a degree in civil engineering rather than mechanical engineering, did not align with the pertinent aspects of aerosol can design. The Defendants further asserted that Cagwin’s expertise in HVAC, plumbing, and fire protection was irrelevant to the design of aerosol cans as consumer products. Additionally, the Defendants highlighted Cagwin’s absence of educational and professional experience in the realm of warning labels on consumer products.

    The Plaintiff responded by asserting that the Defendants were subjecting Cagwin to an “overly narrow test of his own qualifications.” The Plaintiff urged the Court to evaluate whether Cagwin’s “general engineering experience” was sufficient to qualify him to testify in a field where he may lack extensive direct experience. Additionally, the Plaintiff contended that the fact that Cagwin had not personally designed a spray-paint can should impact the weight rather than the admissibility of his testimony. The Plaintiff argued that Defendants had the opportunity to cross-examine Cagwin during the trial to scrutinize the extent of his qualifications.

    The Plaintiff failed to address and counter the main point of the Defendants’ argument, which centered on the perceived lack of relevance between Cagwin’s educational and professional backgrounds and the subject matter he intended to testify about. The Plaintiff incorrectly asserted that the deficiencies in Cagwin’s experience only affected the weight of his testimony, not its admissibility. However, the Court noted that determining whether a witness possesses the necessary qualifications to testify on the subject matter in question is a matter of admissibility, not weight, as established in Hilaire v. DeWalt Indus. Tool Co., 54 F. Supp. 3d 223 (E.D.N.Y. 2014).

    The assertion is made that Cagwin lacked the necessary qualifications to testify about the design of spray-paint cans. This conclusion is drawn from an examination of Cagwin’s overall experience and knowledge, considering both education and employment history. Notably, Cagwin acknowledged during his deposition that the design of aerosol cans fall within the realm of mechanical engineering, a field different from his degree in civil engineering. The absence of specific education is considered, but typically such gaps should be compensated by relevant professional or practical experience, which appears to be lacking in this case. The argument questions how Cagwin’s expertise in the broad category of “pressure vessels” qualifies him to opine on spray-paint can design, and the Plaintiff’s brief is criticized for not establishing the analogy between purported “pressure vessels” like vacuum cleaners, tires, and blimps and the aerosol can in question. Furthermore, during his deposition, Cagwin reportedly admitted that the pressure vessels he listed were structurally distinct from the aerosol can at issue in this case.

    The argument contends that Cagwin is not qualified to testify about the adequacy of the label on the relevant spray-paint can. Aside from his admission during deposition that he lacks expertise in evaluating the sufficiency of consumer product warning labels, Cagwin’s lack of formal education or training specifically related to warning labels is highlighted. His only professional experience with warning labels is noted to be associated with his employment at a gas heat equipment company, where he explained hazards to employees responsible for designing the products’ warning labels. This experience is deemed too distant from warning labels to meet the “specialized knowledge” criteria set by Rule 702 and Daubert. The Plaintiff’s counterargument, stating the Plaintiff’s awareness of indicated dangers on the label, is deemed insufficient. Consequently, it is concluded by the Court that Cagwin lacks the necessary “scientific, technical, or otherwise specialized knowledge” required to serve as an expert witness, particularly in regards to both the design and labeling of spray-paint cans, under Rule 702(a) and Daubert.

    Defendants argue that Cagwin’s “failure-by-shaking” theory lacks support as it relies solely on the Fox report, which they contend is irrelevant as it did not address shaking paint cans, particularly their explosion. They also highlight Cagwin’s failure to test his theory and his inability to elucidate why his suggested alternative design—a straight-walled can made from single-reduced steel—would be safer. In response, the Plaintiff contends that Cagwin drew upon other scientific literature, specifically the report by Robert L. Grunes (the “Grunes report”)(mentioned during his deposition but not in his official report), which allegedly investigated five spray-paint cans that exploded when shaken. The Plaintiff also cites instances where Courts opted not to exclude experts who did not conduct tests on their proposed alternative designs.

    The Court emphasizes the requirement that an expert’s opinion must be substantiated by adequate facts and data, typically from peer-reviewed reports, as outlined in Daubert. Both parties acknowledge that Cagwin primarily relied on the Fox report. The Court determines that the Fox report is irrelevant and insufficient to support Cagwin’s “failure-by-shaking” theory. The Fox report specifically tested the impact of dropping and mechanical abuse on double- and single-reduced steel cans, not the routine effects of shaking steel cans. The Court deems it unreasonable for Cagwin to extrapolate results from a test that imposed extreme, artificial pressure on steel cans to support his theory about routinely shaking cans. Furthermore, Cagwin admitted during deposition that the Fox report did not replicate the failure-by-shaking scenario described by the Plaintiff. The Plaintiff’s main counterargument regarding the Fox report being peer-reviewed is dismissed, as peer review of an irrelevant study does not render it, or Cagwin’s reliance on it, sufficient to support his opinion on an entirely different theory.

    The Plaintiff contends that Cagwin relied on the Grunes report, but the Court notes that this report was not identified in Cagwin’s expert report and was raised for the first time during his deposition. Regardless of the untimely disclosure, the Court finds the Grunes report unpersuasive and unreliable. This report, arising from Rust-Oleum Corporation’s pre-litigation correspondence with its supplier, lacked peer review and did not involve scientific testing. Instead, it collected consumer anecdotes reporting aerosol can failure from routine shaking. Given the report’s adversarial nature, absence of scientific testing, and lack of peer review, the Court deems it unreasonable for Cagwin to extrapolate from these anecdotes and conclude that necked-in cans are more prone to exploding from shaking.

    The Court emphasizes that in situations where an expert’s theory lacks widespread support, as in this case, the expert should undertake independent testing, such as recreating the accident, to substantiate the theory, citing the Toomey v. Millercoors LLC, 86 F. Supp. 3d 202 (E.D.N.Y. 2015) case. The Court notes that the Fox and Grunes reports are the only third-party scientific literature Cagwin allegedly relied upon to support his “failure-by-shaking” theory. Based on this, the Court concludes that Cagwin’s theory lacks broad support, and therefore, he should have conducted his own testing to either confirm or refute his theory.

    In a design-defect case like the present one, the Court notes that an expert bears a special responsibility to present an alternative design and demonstrate, typically through testing, that the proposed alternative would have been safer for the user in the specific accident under consideration. Referring to the Hilaire case, the Court emphasizes that the core of an expert’s report in such cases should involve a comparison of the utility and cost of the product’s design against alternative designs, a comparison that is typically substantiated by testing of the proposed alternative design. Cagwin’s efforts in the design-defect opinion were deemed incomplete. While he asserts that a straight-walled can made of single-reduced steel would likely have averted the Plaintiff’s injury, he falls short in substantiating this claim with evidence, including any testing. The Court emphasizes that Cagwin did not provide proof, even though he acknowledged possessing the capability to do so, to establish that his suggested alternative design would have been safer for the Plaintiff’s use. Consequently, the Court deems Cagwin’s alternative design theory entirely unsupported.

    Defendants contend that Cagwin’s application of his warning label methodology to the case is flawed. They argue that although he stated warning labels should highlight non-obvious risks, he testified that the risk faced by the Plaintiff (can bursting from striking it against a table) was obvious. Additionally, Defendants find Cagwin’s opinion regarding the efficacy of additional warnings nonsensical, as the Plaintiff denies striking the can, and Cagwin’s causation theory does not involve such an action. Furthermore, Defendants highlight the Plaintiff’s inability to recall reading the warning label, leading them to assert that Cagwin’s claim that a different label could have prevented the accident is speculative. Notably, the Plaintiff’s brief does not address or counter the Defendants’ arguments on Cagwin’s warning label-related opinions, effectively conceding the Defendants’ points.

    The Court underscores that an expert witness must consistently apply their methodology to the available facts and data. Cagwin, in this instance, did not meet this requirement. While his stated methodology involved including non-obvious risks on the paint can’s label, he failed to elucidate how this additional warning language would have prevented the Plaintiff’s injury, thus lacking a coherent theory of causation. Notably, Cagwin contradicted his own position by testifying that the addition of a warning label in this case was “immaterial.” This assertion is supported by the fact that the Plaintiff cannot recall reading the can’s label.

    Held

    The Court granted Defendants’ motion to exclude Dale Cagwin’s testimony and report for lack of qualifications and reliability. The Court has not arrived on an outcome for this case since the remaining issues involved in this case still await resolution.

    Key Takeaways

    This case illustrates several important requirements for expert witness testimony to be admissible under Federal Rule of Evidence 702 and Daubert. First, the expert must be properly qualified through education, training, and/or experience specifically related to the issues on which they intend to opine. Generalized expertise is not always sufficient especially coupled with the lack of professional and practical experience. Second, the methodologies and facts relied upon by the expert must sufficiently support their opinions and bear a logical connection to the issues in the case. An expert cannot extrapolate opinions on entirely different issues from unrelated research or data. 

    Additionally, in product liability design defect cases, experts have a special duty to present an alternative feasible design and show through testing that it would have prevented the accident. Speculative testimony that additional warnings could have made a difference is also unreliable when there is no evidence they would have been read or heeded.

    In excluding the engineer’s testimony in this case, the Court scrutinized his qualifications, methodology and reliance on unrelated research, failure to test alternative designs, and speculative opinions regarding causation. This serves as a guidepost for the detailed analysis required to determine if purported expert opinions meet admissibility standards under Rule 702 and Daubert. Careful vetting of expert methodology and logic is necessary to ensure reliability and aid the fact-finder.

  • Court rejects the Firearms Expert Witness’ conclusions with regard to the possibility of the revolver firing without a trigger pull in product liability case

    Court rejects the Firearms Expert Witness’ conclusions with regard to the possibility of the revolver firing without a trigger pull in product liability case

    Freedom Arms manufactured the Model 83 Revolver, a single-action handgun firing a .454 Casull cartridge, designed for defense against large animals. This revolver incorporated a manual safety feature to prevent accidental discharge. The accompanying manual, available online or through various channels, contained numerous warnings against mishandling and provided explicit instructions on using the safety features. The safety mechanism of the Model 83 revolver involved drawing the hammer into the “safety bar” or “safety notch” position. This action engaged a “hammer block” to prevent the hammer from striking the firing pin and accidentally discharging the weapon. The manual consistently emphasized in bold and capitalized text the critical warning to never handle the Casull revolver with a live cartridge in the cylinder chamber aligned with the barrel and firing pin unless fully prepared to shoot at a target. The manual also included step-by-step instructions on how to engage the “hammer block” safely. It also explicitly advised against carrying the revolver in the field with a live cartridge in the chamber aligned with the barrel and firing pin. The company’s warranty guaranteed the firearm’s quality to the original purchaser, defining terms and limitations, and explicitly stating that the written limited warranty superseded any other implied warranties, such as merchantability or fitness for a specific purpose.

    William Hyter bought a used Freedom Arms Model 83 handgun for bear protection but didn’t receive any manuals or instructions upon purchase. Despite his prior experience with firearms, he didn’t seek information about this specific revolver. While metal detecting with his son in a rocky-bottomed creek in bear territory, the handgun fell from his shoulder holster, striking a rock and accidentally firing a bullet into his shoulder. All chambers of the revolver were loaded with live rounds, the safety was disengaged, and the hammer rested directly over a live cartridge when the incident occurred.

    After his injury, on October 30, 2019, William and Sandra Hyter filed this action. In their Complaint, they asserted eight causes of action against the Defendants: (1) strict liability, (2) failure to warn, (3) breach of implied and actual warranty, (4) failure to recall/retrofit, (5) violation of consumer protection laws, (6) ultra-hazardous activity, (7) negligence, and (8) punitive damages. Later, Plaintiffs withdrew their cause of action for “ultra-hazardous activity.”

    Defendant Freedom Arms, Inc. (“Freedom Arms”), moved in limine to preclude Plaintiffs William and Sandra Hyter’s (“Plaintiffs” or “the Hyters”) expert, Jack Belk and for summary judgment on the Hyter’s claims. Plaintiffs responded in opposition to summary judgment and cross-moved for summary judgment in their favor.

    Firearms Expert Witness

    Jack Belk Jr. is a firearms expert witness from Idaho. He graduated from the Law Enforcement Minimum Standards School in 1970. Currently, Jack Belk specializes in building, modifying and designing fine sporting firearms as well as analyzing firearms designs and functions.

    Discussion by the Court

    Belk, as the expert witness presented by the Plaintiffs, outlined two purported design flaws in the Model 83: the absence of a “transfer bar” safety and a “cylinder gap” for checking loaded status. He detailed his methodology in reaching these conclusions, having examined the Model 83 physically and via video. His analysis led him to identify three potential scenarios where the firearm could discharge without trigger manipulation, specifically emphasizing the risk of a “drop fire” incident if the gun fell with the hammer on the firing pin. Belk also discussed alternative designs, referencing the Model 97 and suggesting that a “transfer bar” safety, present in the Model 97, could potentially be implemented in the Model 83 to mitigate or eliminate the risk of unintended discharges.

    The Court determined that while Belk suggested the feasibility of incorporating a “transfer bar” safety system from one Freedom Arms handgun to the Model 83, his analysis lacked depth. Although noting structural similarities between the firearms, Belk didn’t substantiate why or how this safety system could be integrated into the Model 83. This analytical gap hindered the Court’s ability to evaluate the scientific validity of his conclusion. Similarly, Belk’s assertion regarding the absence of a “cylinder gap” suffered from the same flaw. Merely identifying a feature in one firearm couldn’t support the argument that its absence in another constituted a design flaw without further analysis or reasoning.

    Defendants contended that Belk should be prohibited from asserting that any purported defect directly caused Hyter’s injury due to his lack of employing a specific methodology to evaluate causation. While the Court comprehended the methodology Belk applied—drawing inferences from firearm features and technical experience to derive conclusions about causation—the Plaintiffs failed to establish its reliability as an admissible methodology for presentation to a jury.

    Defendants sought to prevent Belk from providing an opinion on the adequacy of warnings for the Model 83 revolver, claiming he lacked qualification for such an assessment. Belk clarified that he did not intend to offer an opinion on this matter, which was evident in his expert report. The Court declined to preemptively exclude an opinion that hadn’t been presented. However, if Belk were to attempt such testimony during trial, Defendants retained the right to object at that time.

    Defendants argued to exclude several of Belk’s opinions as irrelevant. The Court agreed that Belk’s opinion about the Model 83’s lack of a “cylinder gap” was irrelevant. Additionally, the Court found Belk’s opinion on causation, specifically regarding a “drop fire” causing Hyter’s injuries, lacked proven reliability. Concerning Belk’s opinion on the Model 83 firing without a trigger pull, the Court agreed that certain aspects—such as the firearm discharging upon impact when held or if the hammer was manipulated—were not relevant to this case. However, Belk’s opinion that the Model 83 could “drop fire,” consistent with the incident where Hyter’s firearm discharged upon being dropped and striking a rock, was deemed relevant. Nonetheless, Belk’s opinions about other ways the Model 83 could fire without a trigger pull were deemed irrelevant to the matter at hand.

    Defendants sought to exclude Belk’s opinions under Federal Rule of Evidence 403, claiming they were unfairly prejudicial, risked confusing the issues, and might mislead the jury. Despite narrowing the scope of Belk’s permissible opinions, the Court opted not to impose further restrictions on Belk’s testimony under Rule 403 at that juncture. However, the Court permitted Defendants to renew any Rule 403 objections during Belk’s actual trial testimony if they found it necessary.

    Freedom Arms moved for summary judgment dismissing each of Plaintiffs’
    strict liability, failure to warn, breach of implied and actual warranty, failure to recall/retrofit, violation of consumer protection laws, ultra-hazardous activity, negligence and punitive damages claims. Plaintiffs withdrew their ultrahazardous activity claim.

    Freedom Arms’ motion for summary judgment was granted in part and denied in part by the Court with Plaintiffs’ strict liability claim surviving summary judgment.

    Plaintiffs filed a cross-motion for summary judgment, contending that a prior judgment against Freedom Arms in an Ohio case should dictate the outcome of their design defect claim in this case. Additionally, they argued for summary judgment in their favor on multiple fronts: the failure to retrofit or recall claim, breach of warranties claim, causation, negligence claim, strict liability claim, and punitive damages. Freedom Arms countered, stating that Plaintiffs misinterpreted and misapplied the principles of claim and issue preclusion in their argument.

    The Court noted that according to Ohio law, for offensive application of issue preclusion, mutuality of parties is crucial, requiring all present parties to be bound by the prior judgment. Plaintiffs sought to use issue preclusion against Freedom Arms but failed to demonstrate mutuality, as the prior judgment in Taylor v. Freedom Arms involved different parties and a distinct incident. Claim preclusion didn’t apply either because the claims in the current case were not part of the same factual background as those in Taylor v. Freedom Arms. The Taylor case involved an incident where a coat snag caused the revolver’s hammer to partially draw back and discharge, a circumstance entirely separate from the incident in the present case.

    The Court held that Plaintiffs were not entitled to summary judgment on the Defendant’s duty to retrofit or recall claim or on the issues of breach
    of warranties, causation, comparative fault, strict liability, negligence,
    or punitive damages.

    Held

    Freedom Arm’s Motion in Limine to preclude Jack Belk was granted. Freedom Arm’s Motion for Summary Judgment was granted in part and denied in part. Plaintiffs’ Cross-Motion for Summary Judgment was denied. The Court has not arrived on an outcome for this case since the remaining issues involved in this case still await resolution.

    Key Takeaways:

    In this case, the credibility and admissibility of expert witness testimony, specifically that of Jack Belk, emerged as a pivotal aspect. Belk’s testimony centered on purported design flaws in the Model 83 revolver, including the absence of a “transfer bar” safety and a “cylinder gap.” However, the Court scrutinized the depth and scientific validity of Belk’s analysis. It highlighted a critical analytical gap, particularly regarding the integration of safety systems from one firearm to another, which hindered the assessment of Belk’s conclusions. The Court underscored the necessity for expert opinions to be substantiated with comprehensive reasoning and analysis to be deemed reliable for jury consideration.

    Moreover, the Court ruled on the relevance of Belk’s opinions, excluding certain aspects that lacked relevance to the case, such as opinions on the “cylinder gap.” Additionally, the Court scrutinized Belk’s opinions on causation, especially regarding the potential scenarios of the Model 83 discharging without trigger manipulation, emphasizing the importance of a methodology’s reliability in establishing causation.

    The Court’s decision not to restrict Belk’s testimony under Rule 403 highlighted the balance between potentially prejudicial or confusing evidence and the need for a comprehensive evaluation during trial. This case emphasized the pivotal role and stringent criteria for the admissibility of expert witness testimony, underscoring the necessity for methodological rigor, relevance, and scientific validity in supporting expert conclusions before presentation to a jury.
