    Firearms & Ballistics Expert Witness’ Defect and Causation Opinions Excluded

    A district judge in Alabama excluded the testimony of the firearms & ballistics expert because he did not offer any evidence to show any of the alleged dangerous conditions in order to support the product liability claims.

    Plaintiff James Andrew Scott, II filed a complaint against Remington Arms Company, LLC (“Remington”) alleging that defects in the trigger mechanism for a Remington Model 770 bolt-action rifle caused it to fire unexpectedly, resulting in the death of his daughter, Alyssa Brooke Scott.

    On November 13, 2017, 15-year-old Alyssa and her godmother Christal Davis went deer hunting together. After Alyssa and Davis decided to end the hunt, Davis closed the rifle’s bolt and tied a nylon rope through the trigger guard to lower the rifle to Alyssa. Davis testified that she tied the rope behind the trigger and made sure there was no slack in the knot. Alyssa told Davis that she turned on the rifle’s manual safety switch before she handed over the gun, but Davis does not remember personally checking the position of the safety before she began to lower the rifle from the deer stand. 

    Davis lowered the rifle with the muzzle pointing down and the rope fastened through the trigger guard. About halfway down, the gun fired and the bullet struck and killed Alyssa. 

    Before the Court is Remington’s combined motion to exclude the opinions of Plaintiff’s proffered liability expert, Jerry Morris and motion for summary judgment.

    Firearms & Ballistics Expert Witness

    Jerry Morris has been a gunsmith for 51 years and has worked on hundreds of makes and models of firearms, serviced over 10,000 firearms,” and taught classes on gunsmithing. His expert report represented that he “had extensive knowledge and experience with the Remington 770 rifle, and the trigger system in particular.”

    Discussion by the Court

    Rule 26

    Remington argued that Morris’ affidavit is a violation of Rule 26 since it was untimely under the existing scheduling order and consisted of new reasoning and opinions.

    The Court held that Scott “was not allowed to use [the Morris affidavit] to supply evidence on a motion, at a hearing, or at a trial, unless the failure was substantially justified or is harmless.”

    But Scott did not argue that the failure to timely disclose this evidence was substantially justified or harmless, despite being given the opportunity to do so. Instead, Scott stuck to his argument that the evidence was an expansion or elaboration of Morris’ previous testimony, which the Court rejected.

    The Court held that the affidavit did not qualify as a supplementation under Rule 26(e) because it went well beyond correcting or completing inaccuracies or omissions in the original expert report.

    Rule 702

    Remington challenged all of Morris’ opinions. First, Remington contended that he was not qualified to offer his defect opinion and that this opinion was not based on any reliable method-based testing, literature, observations, or experience. Second, Remington argued that Morris’ causation opinion was not supported by any testing, the evidence in this case, or his personal experience.

    1. Qualification

    Morris based his opinion on the manufacturing process of the Model 770’s trigger and sear. He claimed that Remington uses “inferior powdered metal in the components of the trigger system” and that the rough sear contact was unpredictable and inconsistent.

    The Court held that Morris may know a lot about guns, but there is no evidence that he ever investigated or studied the materials in the Model 770 trigger mechanism. He has not designed any fire controls or fire control components and has not reviewed any manufacturing or design records related to the Model 770 rifle. In fact, he admitted that he has only repaired two 770 rifles and cleaned about a dozen in his long history as a gunsmith. And as to this particular gun, he did not measure the sear engagement or contact points between the trigger and sear since he did not have the proper tools. In other words, Morris was not qualified to offer an opinion on the metallurgical properties or design process of the trigger or sear in the Remington Model 770 rifle.

    2. Reliability

    The Court held that even if Morris had the qualifications to offer his opinions, they would fail the reliability prong of the Daubert inquiry.

    To begin with, Morris did not provide any measurements or objective observations of rough contact points or surfaces between the sear and trigger in the rifle at issue here. In fact, he admitted that he did not have the tools to measure them. Likewise, when Morris offered the opinion that the low and inconsistent trigger pull forces he documented resulted from a chipped trigger or rough contact points between the trigger and sear, his testimony merely assumed the presence of a chipped trigger or rough contact points without any evidence supporting that assumption.

    The Court found that Morris did not perform any testing or offer any evidence to show that any of the alleged dangerous conditions—“powdered metal” trigger components, rough sear contact points, a chipped trigger, or inconsistent trigger pull weights—caused the rifle to fire without activating the trigger.

    3. Assisting the Trier of Fact

    The Court found that Morris’ theory that the gun could have bumped the tree as it was lowered to the ground lacked evidence; instead, the uncontroverted evidence from the single surviving eyewitness is that the gun did not bump the tree.

    The Court concluded that multiple portions of Morris’ opinions were not based on facts in evidence, and thus would not assist the trier of fact.

    With the exclusion of Morris’ expert opinions, Remington contended that Scott did not offer sufficient evidence to support his product liability claims. The Court agreed and entered final judgment in favor of Remington and against Scott.

    Held

    The Court granted Defendant’s motion to exclude the opinions of Plaintiff’s proffered liability expert, Jerry Morris.

    Key Takeaway:

    Morris based his defect and causation opinions on the materials and process Remington used to manufacture the trigger and sear. The Court excluded his opinions because he did not produce any literature, reports, or other documentation to support his contention that the Model 770’s components are inferior to other fire controls using different processes or materials. Importantly, he did not provide any testing, explanation, or other support for his theory that using hardened forged steel would create a more consistent contact point between the sear and the trigger. Instead, there is simply no explanation in the record for the methodology he used in reaching his conclusions. Morris has not designed any fire controls or fire control components and has not reviewed any manufacturing or design records related to the Model 770 rifle.

  • Firearms & Ballistics Expert Witness Testimony Rejected for not being based on Empirical Evidence

    Firearms & Ballistics Expert Witness Testimony Rejected for not being based on Empirical Evidence

    In January 2021, Timothy Davis experienced an unexpected discharge of his Sig Sauer P320 XCarry pistol while exiting his vehicle, resulting in a severe leg injury from a 9mm hollow-point bullet. The circumstances surrounding the incident were unclear, with conflicting accounts in Davis’ deposition. He stated that, while sitting in his vehicle, he holstered the P320, and as he extended his leg, the pistol discharged. Davis insisted that the P320 was fully holstered and secured on his left hip.

    However, a police report and an EMT report provided a different version, indicating that Davis was attempting to holster the P320 when the discharge occurred. Regardless, Davis claimed the P320 discharged without a trigger pull, a contention disputed by Sig Sauer.

    In January 2021, Plaintiff Timothy Davis claimed that his Sig Sauer P320 XCarry pistol discharged unexpectedly, injuring his leg with a 9mm hollow-point bullet. Davis provided conflicting accounts of the incident: one stating he holstered the gun before exiting the vehicle, and another suggesting he was attempting to holster it when the discharge occurred.

    Davis filed a product liability and negligence lawsuit against Sig Sauer, alleging that the P320 lacked external safeties, making it unreasonably dangerous. Gunsmith James Tertin and human factors engineer William Vigilante, serving as expert witnesses, argued that the absence of a manual safety rendered the pistol defective, increasing the risk of accidental discharge. They contended that this defect was the proximate cause of Davis’ injury.

    Sig Sauer moved to exclude Tertin and Vigilante’s opinions and sought summary judgment, claiming that without the expert testimony, there was no genuine dispute of material fact, and Davis failed to establish causation.

    Firearms & Ballistics Expert Witness

    James Tertin is currently the director of research and development for Magnum Research, a firearms manufacturer based in Pillager, Minnesota. In that role, he is responsible for designing and developing new firearms for the company.

    He has been a professional gunsmith since graduating in 1972 from the Gunsmithing School at Trinidad State College in Colorado; the oldest gunsmithing school in the United States. Over the past fifty years, he has been awarded seven firearm design patents.

    Human Factors Engineering Expert Witness

    William Vigilante graduated with a Doctoral of Philosophy and a Master’s of Science in Ergonomics (Human Factors) Psychology and a Bachelor of Science degree in Psychology (Cognitive track). He is also a Certified Professional Ergonomist by the Board of Certification in Professional Ergonomics (#2019). He has more than 25 years of experience in psychological and human factors research with a focus on human-machine interaction, control-display design, product design, hazard identification and mitigation, risk perception, situational awareness, perception-reaction time, and the design and testing of warning systems.

    Discussion by the Court

    Federal Rule of Evidence 702 governs the admissibility of expert witness testimony. It permits an expert to testify about scientific knowledge if “(a) the expert’s scientific, technical, or other specialized knowledge will help the trier of fact to understand the evidence or determine a fact in issue; (b) the testimony is based on sufficient facts or data; (c) the testimony is the product of reliable principles and methods; and (d) the expert has reliably applied the principles and methods to the facts of the case.”

    Sig Sauer had challenged the testimony of Tertin and Vigilante on various grounds, asserting that their causation opinions were speculative and lacked reliable foundations. Additionally, Sig Sauer questioned Vigilante’s qualifications to opine on firearm design. Sig Sauer’s primary objective was to exclude Tertin and Vigilante from expressing the view that Davis’ accident might have been prevented with a thumb safety or tabbed trigger safety on the P320.

    The Court concurred with Sig Sauer’s argument, finding that neither Tertin nor Vigilante had a reliable factual basis for their causation opinions. Tertin’s opinion, which stated that any single-action firearm without a manual thumb safety is defective, lacked empirical evidence. Tertin suggested that a tabbed trigger “probably would have prevented the accident,” but he admitted to having no information about what caused Davis’ trigger to depress. Tertin performed no analysis on the circumstances of the accident, providing no basis for his conclusion on the lack of a manual safety being the proximate cause. The Court deemed Tertin’s opinion as pure speculation, lacking any factual foundation or empirical evidence, and therefore inadmissible for proving causation.

    Vigilante’s opinion faced a similar challenge. He contended that the P320’s lack of an external manual safety made it defective and unreasonably dangerous, attributing it to the unintentional discharge in Davis’ case. According to Vigilante, triggers could move through inertia, foreign object contact, or contact with a body part, but he lacked an opinion on how Davis’ trigger became engaged.

    Vigilante admitted to not inspecting Davis’ pistol or holster, relying solely on Davis’ deposition and a sheriff’s report for his understanding of the accident. He did not speak with Davis or review the first responders’ testimony, and no testing or analysis of physical evidence was conducted to validate Davis’ version of the accident. Vigilante’s causation opinion appeared detached from the specific circumstances of Davis’ case, relying on a general conclusion about the P320’s safety without factual support.

    Even Vigilante’s generalized conclusions were based on shaky grounds, using anecdotal data from YouTube videos and a memorandum by the United States Immigration and Customs Enforcement Agency. This lack of empirical evidence failed to meet the standards set by Rule 702 for expert testimony. Even if one assumed the absence of a manual safety was a design defect, Vigilante provided no factual basis for concluding that a manual safety would have prevented Davis’ specific accident. Without a thorough investigation into the accident’s circumstances, Vigilante’s causation opinion was deemed too speculative and lacking reliability. Therefore, his expert testimony was precluded.

    The Court briefly addressed another argument asserted by Davis in support of admitting the expert testimony of Tertin and Vigilante. Davis compared two recent Orders from other district courts that considered similar motions filed by Sig Sauer. In the Northern District of Georgia, Sig Sauer’s motions were partially denied, while in the Western District of Oklahoma, Sig Sauer’s motions were granted. Davis urged the Court to distinguish the Western District of Oklahoma case, Herman V. Sig Sauer, asserting that the facts in the present case were distinct.

    After reviewing both Orders and their supporting records, the Court concluded that Herman was not distinguishable, particularly concerning the reasoning supporting the exclusion of expert testimony by Tertin and Vigilante. Despite the Northern District of Georgia recognizing that the opinions of Tertin and Vigilante were based on the specifics of the incident in that case, the Court found no similar evidence in the present case. Similar to the Herman Court, the Court noted broad conclusions about an alleged defect in Sig Sauer’s P320 applied generally to the case’s facts. Tertin and Vigilante both admitted that the specific circumstances of Davis’ incident weren’t crucial to their opinions. Therefore, as explained above, neither expert could be relied upon to provide an accurate and helpful opinion on what may have caused the injury in Davis’ particular case. Consequently, both experts were precluded from testifying.

    With the exclusion of Tertin and Vigilante, Davis found himself without any expert witness to testify regarding the alleged defect and causation. This absence meant that Davis could not demonstrate the existence of a defect and its role in causing his injury. Consequently, his claims lacked an essential element and failed under Kentucky law. As a result, the Court granted Sig Sauer’s motion for summary judgment.

    Held

    The Case was decided in Defendant, Sig Sauer’s favor after the testimony of both experts, James Tertin and William Vigilante were excluded and Sig Sauer’s motion for summary judgment was granted.

    Key Takeaways:

    The admissibility of expert witness testimony is governed by Federal Rule of Evidence 702, which sets criteria requiring the expert’s knowledge to assist the trier of fact, be based on sufficient facts and data, use reliable principles and methods, and be reliably applied to the case’s facts. In the case against Sig Sauer, challenges were raised against the expert testimony of Tertin and Vigilante, asserting that their causation opinions were speculative and lacked reliable foundations. Additionally, Vigilante’s qualifications to opine on firearm design were questioned. The Court, agreeing with Sig Sauer’s arguments, found that neither expert had a reliable factual basis for their causation opinions, rendering them inadmissible under Rule 702 due to a lack of empirical evidence and factual support. Both experts were criticized for offering broad conclusions about an alleged defect in Sig Sauer’s P320, which were then applied generally to the case’s facts, leading the Court to deem their opinions speculative and lacking a specific connection to the incident in question. Vigilante’s reliance on anecdotal data and Tertin’s admission of no empirical evidence were cited as failures to meet the standards set by Rule 702, which requires a reliable basis for expert opinions. Attempts by the Plaintiff to distinguish the present case from others with varying outcomes were rejected by the Court, emphasizing the lack of similar evidence showing the experts’ opinions were based on the specific circumstances of the incident. With the exclusion of expert testimony, the Plaintiff was unable to demonstrate the existence of a defect and causation, resulting in the failure of claims under Kentucky law. As a consequence, the Court granted Sig Sauer’s motion for summary judgment, underscoring the critical role that expert testimony can play in product liability cases.
