CHRISTOPHER HANSHAW, ) ) Appellant, ) ) ) WD86389 ) v. CROWN EQUIPMENT CORP., ET AL, ) Filed: April 1, 2025 ) Respondent. ) Appeal from the Circuit Court of Jackson County The Honorable Joel P. Fahnestock, Judge Before the Court En Banc: Anthony Rex Gabbert, C.J., and Lisa White Hardwick, Alok Ahuja, Mark D. Pfeiffer, Karen King Mitchell, Cynthia L. Martin, Gary D. Witt, Edward R. Ardini, Jr., Thomas N. Chapman, W. Douglas Thomson, and Janet Sutton, JJ. Christopher Hanshaw was involved in a forklift accident in August 2016, which resulted in the amputation of his left leg below the knee. Hanshaw sued the manufacturer of the forklift, Crown Equipment Corporation, in the Circuit Court of Jackson County. Hanshaw alleged that Crown's forklift was defectively designed. Hanshaw retained an expert witness, who opined that the forklift was unreasonably dangerous because it lacked a door which would have prevented Hanshaw's leg from exiting the forklift's operator compartment, and would thus have prevented his injury. The circuit court granted Crown's motion to exclude Hanshaw's expert. The court found that Hanshaw's expert was not sufficiently
2 qualified, and that his opinions were not reliable. Based on its exclusion of Hanshaw's expert, the court then granted Crown's motion for summary judgment on Hanshaw's negligence and strictly liability design defect claims. Hanshaw appeals. We conclude that Hanshaw's proffered expert was sufficiently qualified, and that his opinions were reliably based on his education, experience, and analysis of the evidence in this case. We accordingly reverse the circuit court's order excluding Hanshaw's expert from testifying, as well as its grant of summary judgment to Crown based on the exclusion order. The case is remanded to the circuit court for further proceedings on Hanshaw's product defect claims. Factual Background In August 2016, Hanshaw was employed by Valu Merchandisers, a subsidiary of Associated Wholesale Grocers, in Fort Scott, Kansas. He worked in a warehouse. On August 25, 2016, Hanshaw was operating a Crown RC5500 stand-up forklift. The RC5500 is a "side-stance" forklift, in which the operator stands facing to the left, perpendicular to the direction of travel. Because of this side- stance orientation, the forklift's operator can view both the front and back of the forklift with a turn of the head, whether the forklift is traveling with the "forks forward," or with the "forks trailing" (i.e., the "reverse" direction). The operator compartment of Crown's forklift is enclosed on three sides, but is open toward the rear of the forklift, where the operator's left leg is positioned. Although Crown had previously supplied Ford Motor Company with side-stance forklifts with a door fully enclosing the operator compartment, the
3 forklift Hanshaw was operating was not equipped with any type of door on its rear-facing side. Crown contends that the addition of a rear door on the forklift would increase the risk of injury, because a door would prevent the forklift's operator from quickly exiting from the operator compartment in the event the forklift were to tip over, or fall off a loading dock (what are known as "stability" accidents). Hanshaw testified that his accident occurred on August 25, 2016, while he was operating a Crown RC5500 forklift in the forks-trailing direction. He testified that he attempted to stop the forklift by lifting his left foot off a "dead man's" brake pedal on the floor of the operator compartment. (While Hanshaw described this maneuver as "plugging," "plugging" is a different method of slowing or stopping a forklift.) Hanshaw alleged that the forklift did not respond to his actions, and struck a metal pole. As the forklift was traveling, Hanshaw's left leg came out of the operator compartment, and his left foot was crushed between the forklift and the pole. As a result of his injuries, Hanshaw's left leg was amputated below the knee. In August 2018, Hanshaw filed suit in the Circuit Court of Jackson County against Associated Wholesale Grocers, Crown, and the distributors of the forklift. (Hanshaw voluntarily dismissed his claims against Associated Wholesale Grocers and the forklift's distributors, and they are not involved in this appeal.) The circuit court granted Hanshaw leave to file a First Amended Petition in March
Hanshaw's First Amended Petition alleged that Crown negligently designed the forklift, and had negligently failed to warn users of the forklift's dangers. He
4 also asserted strict liability claims alleging that the forklift was defectively designed and manufactured, and that Crown had failed to adequately warn users. Hanshaw sought to recover both compensatory and punitive damages. To support his design defect and failure to warn claims, Hanshaw retained Expert. 1 Expert opined that Crown's forklift was negligently designed and unreasonably dangerous, because it failed to include a door to fully enclose the operator compartment. Expert also opined that Crown should not sell its stand- up side-stance forklifts for general warehousing uses, but should instead offer its customers other types of material handling equipment. Finally, Expert opined that Crown should add a rear bumper to its stand-up forklifts. Expert did not proffer any opinions relating to the adequacy of the warnings provided with the forklift. Hanshaw filed a motion to apply Missouri damages law, and Kansas liability law, to the claims asserted in his petition. The circuit court granted that motion in December 2022, and that ruling is not challenged on appeal. On December 19, 2022, Crown filed a motion for summary judgment, and simultaneously filed a motion to exclude Expert's testimony. Crown's exclusion motion argued that Expert is not qualified to provide any opinion relating to the adequacy of the design of Crown's forklifts, and that Expert's opinions are not reliable. Crown's motion for summary judgment contended that, because of "the complex mechanical nature of the forklift and its design components," expert 1 Section 509.520.1, RSMo Cum. Supp. 2024, provides that "any judgments or orders issued by the court . . . shall not include the following confidential and personal identifying information: . . . (5) Witness information, including the name, address, and other contact information of the witness." As required by the statute, this opinion does not identify Hanshaw's retained expert by name.
5 testimony was necessary to support Hanshaw's design defect claims. Crown argued that, if Expert's opinions were excluded, then it was entitled to summary judgment on the merits of Hanshaw's claims. Crown's summary judgment motion separately argued that, even if Hanshaw could otherwise establish the existence of triable issues on his design defect claims, Crown was entitled to summary judgment concerning Hanshaw's prayer for punitive damages. The circuit court granted Crown's motion to exclude Expert's testimony in an order entered on June 5, 2023. In finding Expert's testimony to be inadmissible, the circuit court relied heavily on an unpublished federal district court decision excluding Expert's opinions, which had been issued thirteen years earlier in another products liability case involving a forklift. Newell Rubbermaid, Inc. v. Raymond Corp., No. 5:08CV2632, 2010 WL 2643417 (N.D. Ohio July 1, 2010). With respect to Expert's qualifications, the circuit court noted that, [s]ince the Newell case, [Expert] obtained a license to operate a forklift, but still does not have extensive experience operating it and no experience operating it in the field. He was trained by his employer and the remainder of his training was self-taught. He trained one or two people to drive the forklift, but they were also employees at his office. He still has not designed a forklift or any component part for any piece of handling equipment. He also has not attended any [American Society of Mechanical Engineers (or "ASME")] meetings or proffered to it alternative designs. Finally, he does not refer to himself or hold himself out as a biomechanical engineer. The circuit court also concluded that, as in the Newell case, Expert's opinions concerning a defect in the forklift's design were unreliable because his methodology was unsound. The court explained: [H]ere [Expert] has conducted no injury potential testing on his proffered design alternatives. He cannot point to any door design or
6 bumper he has developed, prototyped, or tested, or any testing to measure the injury potential to stand-up forklift operators in off- dock and tip-over accidents on forklifts equipped with a door or bumper. Like in Newell, [Expert] conducted acceleration testing and additionally here he also evaluated egress times from stand-up forklifts, but not on the forklift at issue. No evidence was presented that he performed any tests to see if the alternative designs are both economically feasible and just as safe or safer than the model without the door. With respect to the testing conducted by [Expert], he has not shown the reliability of this testing and how it relates to and supports his proffered designs. Because Expert had "testified he would not come to trial with an opinion regarding warnings," the circuit court found that he was not competent to offer opinions on that subject either. Following its ruling excluding Expert's opinions, the circuit court granted Crown's motion for summary judgment the next day. Because it granted summary judgment to Crown on all of Hanshaw's claims, the circuit court did not separately address Crown's motion for summary judgment on Hanshaw's prayer for punitive damages. Hanshaw appeals. Discussion I. In his first two Points Relied On, Hanshaw contends that the circuit court erroneously determined that Expert was unqualified to offer expert opinions concerning the design of Crown's forklift, and that Expert's design defect opinions were unreliable. We agree. "We review the circuit court's decision to exclude expert testimony for an abuse of discretion." Campbell v. Union Pac. R.R. Co., 616 S.W.3d 451, 474 (Mo. App. W.D. 2020).
7 The admissibility of Expert's testimony is governed by § 490.065.2, 2 which provides in relevant part: (1) A witness who is qualified as an expert by knowledge, skill, experience, training, or education may testify in the form of an opinion or otherwise if: (a) The expert's scientific, technical, or other specialized knowledge will help the trier of fact to understand the evidence or to 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[.] The test for admissibility codified in § 490.065.2 can be "boil[ed] . . . down to its essence in a useful three-part test: (1) whether the expert is qualified, (2) whether the testimony is relevant, and (3) whether the testimony is reliable." State ex rel. Gardner v. Wright, 562 S.W.3d 311, 319 (Mo. App. E.D. 2018) (citations omitted). "Section 490.065.2 adopts the Federal Rules of Evidence word-for-word . . . ." Id. at 317. This Court has recognized that Federal Rule of Evidence 702, on which § 490.065.2 is patterned, "reflects an attempt to liberalize the rules governing the admission of expert testimony." Jones v. City of Kansas City, 569 S.W.3d 42, 56 (Mo. App. W.D. 2019) (cleaned up), overruled on other grounds by Wilson v. City of Kansas City, 598 S.W.3d 888, 895-96 (Mo. 2020).
2 Statutory citations refer to the 2016 edition of the Revised Statutes of Missouri, updated by the 2024 Cumulative Supplement.
8 Missouri courts have stated that under § 490.065.2, circuit courts must act as "gatekeepers" to prevent irrelevant or unreliable expert testimony from being presented at trial. See, e.g., Gebhardt v. Am. Honda Motor Co., 627 S.W.3d 37, 44 (Mo. App. W.D. 2021) (quoting Ingham v. Johnson & Johnson, 608 S.W.3d 663, 700 (Mo. App. E.D. 2020)). Our decisions also make clear, however, that a pre-trial motion to exclude expert testimony is no substitute for the trial itself. The trial court's role as gatekeeper is not intended to serve as a replacement for the adversary system. In deciding whether to admit an expert's testimony, the circuit court is required to ensure that all of the statutory factors are met; however the court is not required to consider the degree to which they are met. 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. Ingham v. Johnson & Johnson, 608 S.W.3d 663, 701-02 (Mo. App. E.D. 2020) (cleaned up). The Missouri Supreme Court has instructed that, "'[s]o long as the expert is qualified, any weakness in the expert's knowledge is for the jury to consider in determining what weight to give the expert.'" Linton by Linton v. Carter, 634 S.W.3d 623, 628 n.5 (Mo. 2021) (quoting Kivland v. Columbia Orthopaedic Grp., LLP, 331 S.W.3d 299, 311 (Mo. 2011)); see also, e.g., Ingham, 608 S.W.3d at 701; Crowder v. Ingram Barge Co., 681 S.W.3d 641, 646 (Mo. App. E.D. 2023) ("If the expert is sufficiently qualified, . . . the decision to accept his or her analysis of the facts and data is for the jury to decide." (citations omitted)); Revis v. Bassman, 604 S.W.3d 644, 655 (Mo. App. E.D. 2020); State v. Marshall, 596 S.W.3d 156, 161 (Mo. App. W.D. 2020).
9 In sum, "[a]s long as an expert's testimony rests upon good grounds, based on what is known, it should be tested by the adversary process with competing expert testimony and cross-examination, rather than excluded by the court at the outset." Jones, 569 S.W.3d at 56 (cleaned up). II. We first address whether Expert was "qualified as an expert by knowledge, skill, experience, training, or education" within the meaning of § 490.065.2(1). Because Expert's education, training, and experience abundantly qualify him to testify concerning the design and operation of Crown's forklift, we conclude that the circuit court abused its discretion in finding Expert to be unqualified. Expert is a registered professional engineer with bachelor's and master's degrees in mechanical engineering. He is board certified in forensic engineering, and is accredited as an accident reconstructionist. Expert has studied the design and safety of stand-up forklifts for more than fifteen years. During that time, he has been a co-author of six peer-reviewed, published articles concerning the design, operation and safety of stand-up forklifts. One paper examined the frequency and severity of various types of accidents involving Crown's stand-up forklifts, based on a review of multiple years' worth of accident reports filed with the federal Occupational Safety and Health Administration (or "OSHA"). Another article which Expert co-authored studied the acceleration and deceleration forces which are generated in operation of stand-up forklifts, which can cause operators to lose their balance, and can cause their limbs to be ejected from the open operator compartment. A third paper studied the relative times it took for operators to exit from stand-up forklifts with and without compartment
10 doors; this article tested the industry's main objection to the installation of doors on stand-up forklifts. The following passage from Expert's deposition summarizes the testing he has conducted involving stand-up forklifts like the one Hanshaw was operating at the time of his accident: I've done performance testing of forklifts, including the lateral and longitudinal acceleration of forklifts as they are in operation and during braking and steering. I've conducted testing of collisions of stand-up rider forklifts and evaluated the horizontal intrusion guarding of those forklifts. I've conducted testing to evaluate the acceleration and speeds during those type of collisions. I've evaluated egress times and egress testing from stand-up rider forklifts utilizing an operator compartment guard. In addition, Expert testified that, working with a more senior colleague, he had been involved in "between 15 and 30" legal matters involving injuries resulting from the operation of stand-up forklifts. In those cases, as here, Expert and his colleague took the position that "a stand-up rider forklift should be equipped with an operator equipment guard or door." Expert also has practical experience operating stand-up forklifts. He is licensed to operate a stand-up forklift, and has operated stand-up forklifts manufactured by multiple different companies for between 25 and 50 hours. Expert has also been certified to train others to operate stand-up forklifts, has trained two other individuals, and has compiled training materials for purposes of teaching others how to operate such equipment. Federal courts have permitted experts with similar, or lesser, qualifications to offer precisely the same design defect opinions as Expert. In Anderson v. Raymond Corp., 61 F.4th 505 (7th Cir. 2023), the United States Court of Appeals
11 for the Seventh Circuit recently reversed a district court's exclusion of an expert who offered an opinion identical to Expert's: that a stand-up forklift was defective because of its failure to fully enclose the operator compartment with a rear door. In finding the expert to be qualified, Anderson noted his graduate education in mechanical engineering, the expert's possession of "a license to operate a stand-up forklift like that at issue here," and the fact that the expert had "spent most of his professional career" as a forensic engineer, "investigating machine accidents and performing accident reconstructions." Id. at 509. Unlike Expert, the expert in Anderson had "limited experience with forklifts." Id. The Court held this was irrelevant: "An expert's specialization or lack thereof typically goes to the weight to be placed on [his] opinion, not its admissibility. Ordinarily, courts impose no requirement that an expert be a specialist in a given field." Id. (cleaned up). 3 Expert was substantially more qualified than the expert at issue in Anderson. The circuit court found that Expert was not qualified for the following reasons:
3 Other federal cases reach the same result as Anderson. See, e.g., Jones v. Raymond Corp., 2023 WL 309055, at *4 (N.D. Miss. Jan. 18, 2023) (finding same expert at issue in Anderson to be qualified to offer similar opinions; noting that, "although [expert] may not have specifically specialized in stand-up lift trucks, he has experience in engineering design, product design, accident investigation, and accident reconstruction."); McHale v. Crown Equip. Corp., 2021 WL 289346, at *2-*5 (M.D. Fla. Jan. 28, 2021) (same); Hernandez v. Crown Equip. Corp., 92 F. Supp.3d 1325, 1345 (M.D. Ga. 2015) (expert qualified where he possessed bachelor's and master's degrees in mechanical engineering, and "has conducted over two hundred investigations dealing with injuries to drivers of stand-up forklifts, and has reviewed thousands of accident reports from various forklift manufacturers, OSHA, and state agencies. His analysis and research in the area of forklift accidents were the subject of a peer-reviewed paper he presented to the American Society of Mechanical Engineers ('ASME') in 2011.").
12 Since the Newell case, [Expert] obtained a license to operate a forklift, but still does not have extensive experience operating it and no experience operating it in the field. He was trained by his employer and the remainder of his training was self-taught. He trained one or two people to drive the forklift, but they were also employees at his office. He still has not designed a forklift or any component part for any piece of handling equipment. He also has not attended any ASME meetings or proffered to it alternative designs. Finally, he does not refer to himself or hold himself out as a biomechanical engineer. Given Expert's extensive education, training, and experience, the circuit court's quibbles cannot justify the wholesale exclusion of Expert's testimony at trial. As explained above, "'[i]n deciding whether to admit an expert's testimony, the circuit court is required to ensure that all of the statutory factors are met; however the court is not required to consider the degree to which they are met.'" Ingham, 608 S.W.3d at 702 (emphasis added; quoting Kivland, 331 S.W.3d at 311). While Expert may not have designed a forklift or forklift component, he is plainly highly knowledgeable concerning the safety issues surrounding the design and operation of stand-up forklifts. It may be that a mechanical engineer who had actually designed the operator compartment of a side-stance, stand-up forklift would be more qualified than Expert to testify to the relative merits of that design. But whether a more qualified expert may exist is not the question. The same could be said of the circuit court's criticism that Expert "does not have extensive experience operating [a stand-up forklift] and no experience operating it in the field." While others may have more than the 25-50 hours of operating experience which Expert possesses, and may have actually worked as forklift operators in a warehouse, § 491.065.2 does not require that Expert be the most qualified possible expert witness. The fact that he has been certified to
13 operate a stand-up forklift, and to train others to do so, plainly constitutes a relevant qualification, even if additional qualifications may exist. Although the circuit court found Expert to be unqualified because he "has not attended any ASME meetings," three of Expert's most salient articles concerning the design and safety of stand-up forklifts – and of Crown's forklifts in particular – were published by ASME: the articles analyzing Crown's accident data; measuring egress times from the forklift's operator compartment with and without a rear door; and measuring the acceleration forces generated by stand-up forklifts during deceleration and turning maneuvers. The fact that Expert may not have physically attended ASME meetings, and presented his papers there, is not disqualifying. Finally, the circuit court's statement that Expert "does not refer to himself or hold himself out as a biomechanical engineer" ignores the fact that, in his deposition and in an affidavit submitted to the court, Expert explained that he has "education and experience in the field of biomechanics," and that he has previously "qualified and testified regarding occupant kinematics, forces and motion of vehicle occupants, during car crashes." The circuit court applied an unrealistic and overly demanding standard in assessing Expert's qualifications. As Hanshaw's opening Brief cogently observes, the trial court wanted someone that: (1) worked in a warehouse operating a forklift; (2) also worked for a company, presumably as a mechanical engineer, designing forklifts; (3) attended ASME meetings or sent alternative design suggestions to ASME; and (4) was also a biomechanical engineer. The circuit court insisted on an unreasonable combination of experiences in order for Expert to be considered "qualified" within the meaning of
14 § 490.065.2(1). It was not necessary for Expert to be the proverbial "unicorn" for Hanshaw to be entitled to present his opinions to the jury at trial. The circuit court abused its discretion in excluding Expert's opinions based on its conclusion that he was unqualified to offer them. III. The circuit court also abused its discretion in concluding that Expert's design defect opinions were not reliable. A. When reviewing Expert's design-defect opinions, it is important to bear in mind that, under Kansas law, Hanshaw does not have the burden to establish a safer alternative design for Crown's forklift. The Kansas Supreme Court has explicitly rejected the definition of a design defect found in the Restatement (Third) of Torts: Products Liability. The Restatement provides that "a product is defective in design where 'the foreseeable risks of harm posed by the product could have been reduced or avoided by the adoption of a reasonable alternative design . . ., and the omission of the alternative design renders the product not reasonably safe.'" Delaney v. Deere & Co., 999 P.2d 930, 944 (Kan. 2000) (quoting Restatement (Third) of Torts: Products Liability § 2(b)). In rejecting the requirement that the plaintiff prove the greater safety of an alternative product design, the Kansas Supreme Court explained: Kansas law has been clear in allowing evidence of the feasibility of an alternative design in the trial of a design defect. However, Kansas has consistently held that evidence of a reasonable alternative design may but is not required to be introduced in a design defect action. Kansas has not used the concept of reasonable alternative design to become the standard by which the questioned product is measured.
15 . . . . The Third Restatement's requirement that a plaintiff produce a reasonable alternative design has been harshly criticized. [One commentator] states that the reasonable alternative design requirement is not supported by public policy or economic analysis because the cost of processing a case will make it economically impossible to produce a reasonable alternative design in a small products liability case. Further, contrary to the view of the authors of the Third Restatement that the majority of states require a reasonable alternative design to establish a design defect, research . . . indicates that very few states in fact have this requirement. . . . It is clear in Kansas that evidence of a reasonable alternative design may be presented but is not required. We adhere to this principle and believe that it represents the majority rule in this country. Id. at 945-46 (citations omitted); see also Moore v. Ford Motor Co., 332 S.W.3d 749, 759–60 (Mo. 2011) ("Missouri does not require a plaintiff to create an alternative design to prove a design defect claim; it is enough that plaintiff show that the design used was defective and unreasonably dangerous." (citation omitted)). Thus, in evaluating the reliability of Expert's opinions, we must be mindful that Hanshaw's burden was only to prove that Crown's forklift was unreasonably dangerous – not that a specific alternative design would have made it safer. We first address the circuit court's exclusion of Expert's opinion that Crown's forklift was defectively designed because of the lack of a door. Contrary to the circuit court, we conclude that Expert had a substantial, reliable basis to offer this defective design opinion. The primary basis on which the circuit court found Expert's opinions to be unreliable was that "[h]e cannot point to any door design or bumper he has developed, prototyped, or tested, or any testing to measure the injury potential to
16 stand-up forklift operators in off-dock and tip-over accidents on forklifts equipped with a door or bumper." This statement misapplies the law, and fundamentally misstates the record. The stringent testing standard the circuit court applied to Expert's design defect opinions is legally unfounded. In the circuit court and again on appeal, Crown criticizes Expert for not having conducted "injury potential testing" of his alternative designs using anthropomorphic dummies. The circuit court adopted that criticism, and added that Expert "cannot point to any door design or bumper he has developed, prototyped, or tested." However, Expert was not required to actually design, patent, prototype, and test an alternative design for Crown's forklift in order to be able to testify that the existing design is unreasonably dangerous. Nor was he required to determine the economic feasibility of an alternative design. As the Kansas Supreme Court explained in Delaney, if this level of analysis were required, "the cost of processing a case will make it economically impossible to produce a reasonable alternative design in a small products liability case." 999 P.2d at 946. Caselaw holds that building and testing an alternative design may be unnecessary where the alternative design is available in the marketplace. In this case, Hanshaw emphasized to the circuit court that Crown itself provided doors on the operator compartments of the forklifts it sold to Ford Motor Company until 2008, and offered doors as optional equipment to other customers until
- Similar doors are offered by other manufacturers. The deployment of rear
doors on commercially available stand-up forklifts reduces, if not eliminates, the need for Expert to have himself tested the feasibility and safety consequences of
17 installing a door. See Anderson v. Raymond Corp., 61 F.4th 505, 510 (7th Cir. 2023) ("Raymond's customers who have elected to fit their forklifts with Raymond's optional door have been testing [plaintiff's expert's] alternative for him. Raymond can critique the use of those customers as comparators, but such arguments go to the weight, not the admissibility, of [expert's] testimony."); Jones v. Raymond Corp., 2023 WL 309055, at *7 (N.D. Miss. Jan. 18, 2023) ("'where the proposed alternative design has been produced and put to practical use in the industry, the expert does not need to personally test it to satisfy Daubert'" (citation omitted)); McHale v. Crown Eqpmt. Corp., 2021 WL 289346, at *3 (M.D. Fla. Jan. 28, 2021) (permitting expert to testify to the defective design of Crown's RC5500 forklift due to its lack of a rear door and alternative braking system, based in part on the fact that "forklifts with rear doors and with [expert's] proposed brake system have been produced and put to practical use in the industry"); Gott v. Raymond Corp., 2008 WL 11452486, at *6 (N.D. W.Va. Dec. 19, 2008) (permitting expert to testify to defective design of stand-up forklift without a rear door, despite expert's failure to design or test an alternative design; noting that, "in an apparent recognition of the fact that their stand-up lift trucks can be hazardous without doors in certain situations, The Raymond Corporation has produced spring loaded doors for their forklifts"). In any event, while Expert may not have conducted the level of prototype design and testing necessary to bring a new product to market, he has conducted research and testing which supports the opinion that his proposed design is safer than Crown's open-compartment design. As Crown explains in its Brief, the
18 industry's resistance to the installation of doors on stand-up forklifts has been primarily based on the following reasoning: (1) Operators of stand-up rider forklifts have the best chance to avoid serious injury in tipover and off-the-dock accidents by exiting the machine; and (2) a door would hinder that maneuver. Expert's research has tested, and evaluated, the reasoning underlying the industry's resistance to operator-compartment doors. His research also illuminates whether the installation of doors would have net positive, or negative, effects on operator safety. Expert has done this in three ways.
- Expert testified in his deposition that he conducted testing of the
egress times from a Crown RC3000 forklift, the predecessor to the RC5500 forklift which Hanshaw was operating. Crown's corporate representative testified that the operator compartment of the RC3000 is configured similarly to an RC5500. (Given that its operator compartment is similarly configured, the circuit court's complaint that Expert had not conducted egress-time testing "on the forklift at issue" misses the mark.) Expert testified that he and his co-authors tested egress times when the forklift was equipped with no door, with a spring- loaded door, and with a "latched" door (with a crash-bar) which Expert had designed and installed. The results of Expert's analysis were peer-reviewed, and published in the ASME's proceedings. 4
4 Because of the confidentiality rules imposed by § 509.520.1(5), RSMo, we do not provide complete citations to any of the articles of which Expert was a co-author. See footnote 1, above. The circuit court was provided with full citations to each of Expert's published articles concerning the safety and performance of stand-up forklifts. In the circuit court and on appeal, the parties have discussed the contents of those articles, and have debated whether Expert's articles provide support for the opinions he offers in this case. Nevertheless, the articles themselves were not filed with the circuit court, and have not been made part of the record on appeal. We do not decide whether, in these
19 Crown acknowledges that Expert's egress-time article "mentioned the alternative designs he proposes in this case." Nevertheless, it dismisses that article by contending that [t]he sole purpose of that article was to test the egress times for operators exiting stand-up forklifts with a door, not to study the safety aspects of his proposed designs and the serious risks presented with adding an operator compartment barrier/door in collision, tipover, or off-the-dock accidents. Crown's assertion that Expert's egress-time article did not "study the safety aspects of [Expert's] proposed designs" is simply a non sequitur. Crown's own Brief asserts that the primary safety concern with the installation of doors on stand-up forklifts is that "a door would hinder th[e] maneuver" of an operator exiting the vehicle in a tip-over or off-the-dock accident. See Anderson, 61 F.4th at 510 (noting that "the need for a quick escape in [stability accidents] was [another manufacturer's] justification for not fitting a door as standard"). Expert's egress-time study tests the accuracy of this very claim. It is inaccurate for the circuit court, and for Crown, to claim that Expert has failed to test the safety implications of door installation. See Hernandez v. Crown Equip. Corp., 92 F. Supp.3d 1325, 1346 (M.D. Ga. 2015) (permitting another expert to testify to the results of an egress-time study similar to that conducted by Expert, even though expert's study was performed on a forklift designed by a different manufacturer).
circumstances, it is appropriate for the Court to refer to the content of the articles themselves. Instead, we have relied only on the description of Expert's published articles contained in his deposition testimony and supplemental affidavit, both of which were filed with the circuit court in connection with Crown's exclusion motion. As in all litigation, parties should be mindful to include in the record, both in the circuit court and on appeal, all materials necessary to the disposition of contested issues.

- Besides conducting an experiment which challenged the belief that
doors would "hinder th[e] maneuver" of exiting the operator compartment in a tip-over or off-the-dock accident, Expert also conducted a detailed review of years' worth of Crown's own accident reports. Based on that review, Expert concluded that – for stand-up forklifts – collision accidents like the one Hanshaw experienced are a far more serious concern than "stability" accidents like tip- overs or off-the-dock accidents. Expert conducted his most detailed review of Crown's stand-up forklift accident data in 2008, but updated it thereafter. Post-2008, Expert's analysis "focused on the OSHA fatal accident and injuries databases and an analysis of that information that's publicly available." Based on his review of the accident data, Expert concluded that tip-over accidents "are not very severe accidents in terms of the acceleration and the forces applied to the operator"; he also testified that "it's unlikely that you're going to sustain fatal injuries" in such an accident. Expert concluded that "collisions are much more deadly, much more serious for the operators of stand-up forklifts than sit-down forklifts." Expert's review indicated that 76% of lower limb injuries are caused by the operator's leg inadvertently exiting the operator compartment. Expert specifically disagreed with OSHA's conclusion that tip-over accidents presented the greatest risk of serious injury during operation of stand-up forklifts. He noted that OSHA had "lump[ed] . . . stand-up forklifts and sit-down forklifts all into the same category"; for that reason, "OSHA's characterization of the data I think is misleading and unhelpful." See Hernandez, 92 F. Supp.3d at 1346 (permitting expert to offer design defect opinions similar to Expert's, based in part on the expert's review of
21 Crown accident reports, and his conclusion that lower-limb crush injuries represented "'a very large number of serious, disabling injuries'").
- Besides leading him to conclude that collision accidents are a more
serious risk than stability accidents, Expert's comprehensive review of Crown's accident reports also revealed that exiting the operator compartment of a stand- up forklift is not the safest course in an off-the-dock accident. Instead, Expert concluded that the primary risk to operators in "off-the-dock" accidents is the danger of being crushed by the falling forklift if the operator ejects. During his deposition, Expert testified as follows: Q. And do off-the-dock accidents present life-threatening injury potential to an operator? A. I think that they do. I don't think that they necessarily come from the potential for head injury or spinal injury, again, as the VRC/SEA-type testing would suggest, I think that they present life- threatening injuries from the potential of being crushed by the forklift. Q. And, in fact, from your review of accident reports, operators have been killed in off-the-dock accidents; correct? A. Yes. Again, primarily as a result of being crushed by the forklift, not as a result of sustaining head impact injuries or spinal injuries from falling on the ground. Because of the risks of being crushed if the operator ejects in an off-the-dock accident, Expert testified that he would not recommend that operators eject in all cases, and that operators are effectively in a "no-win situation" when stand-up forklifts are used near loading docks; "[i]t's a dangerous situation to go off-the- dock in a stand-up forklift regardless of whether you jump or stay or are ejected." Expert's conclusion that an operator would be safer remaining in the forklift in a stability accident, based on his analysis of Crown's accident data, is reliable, and
22 "will assist the jury, since Crown contends that the addition of a door on the RC5500 would impede an operator's egress from the operator compartment during a tip-over or off-the-dock incident." McHale, 2021 WL 289346, at *4. * * * * * The criticism that Expert has not tested the safety of an alternative forklift design incorporating compartment doors, or performed "injury potential" testing, suggests that Expert failed to evaluate the risk to operators from tip-over and off- the-dock accidents, as compared to the risk of lower-limb injuries in collisions. But Expert did analyze comparative egress times with and without doors, and he performed a detailed analysis of accident reports involving stand-up forklifts (which indicated that collision accidents present the far greater risk, and that ejecting from a falling stand-up forklift presents its own risks). Given the testing and research Expert has conducted, his failure to conduct "injury potential" testing using anthropomorphic dummies is not disqualifying. Expert's research supports his conclusions that doors will not materially hinder operators from exiting a forklift in an emergency; that exiting the forklift may not be the safest course of action in a stability accident in any event; and that guarding against collisions is a more important means of reducing fatal and serious-injury accidents than taking precautions against stability accidents. In its briefing, Crown emphasizes that equipping stand-up forklifts with doors would be inconsistent with ASME/ANSI standards, and with OSHA regulations. Crown does not argue, however, that those standards or regulations prohibit the installation of doors. Expert's disagreement with standard-setting organizations or government regulators is not disqualifying. See Anderson, 61
23 F.4th at 511 ("While ANSI may suggest a preference for open operating compartments, we are aware of no case stating that an expert who disagrees with ANSI's suggestion is categorically barred from testifying. Just the opposite: ANSI's recommendation, standing alone, is not a dispositive consideration." (cleaned up)). Moreover, at oral argument Crown's counsel acknowledged that the standards and regulations permit the installation of doors at least in certain circumstances. We note once again that Crown actually produced stand-up forklifts with latching doors for Ford Motor Company until 2008, and only discontinued the installation of doors on its stand-up forklifts in 2010. The fact that Expert's opinions may disagree with recommendations made by regulators and safety organizations will plainly provide a substantial basis for Crown to challenge the credibility of his opinions; the inquiry under § 490.065.2 is not intended to decide the persuasiveness of an expert's opinions, however. The fact that Expert's opinions may be contrary to the views of government regulators and engineering organizations is an issue for a jury to weigh – it is not a basis to exclude Expert's opinions entirely. For the foregoing reasons, we find that the circuit court abused its discretion in excluding Expert's design defect opinions based on its conclusion that those opinions were unreliable. B. The dissenting opinions do not attempt to defend the circuit court's conclusion that Expert was unqualified. They argue, however, that the circuit court acted within its discretion in finding that Expert's opinions were not reliable.
24 The dissenting opinions' primary contention is that Hanshaw relied on an outdated version of § 490.065 in opposing Crown's motion to exclude Expert's testimony. The dissents claim that due to his reliance on old law, Hanshaw mistakenly argued that Expert's opinions were admissible based solely on his general qualifications, and made no effort to show that Expert's opinions were based on the reliable application of reliable principles and methods. The dissents' characterizations of Hanshaw's circuit-court briefing are incomplete. Admittedly, Hanshaw's response to Crown's exclusion motion mistakenly included a block quotation of §§ 490.065.1 to .4, RSMo 2016 – a statute which was substantially amended by the General Assembly in 2017. Despite this erroneous quotation, however, Hanshaw's response to the motion to exclude cited State ex rel. Gardner v. Wright, 562 S.W.3d 311, 317 (Mo. App. E.D. 2018), which interprets and applies the current version of § 490.065.2. Hanshaw cited Wright for its recognition that the post-2017 version of § 490.065.2 "is identical to Federal Rules of Evidence 702-705." Hanshaw also quoted the three- part test Wright used to summarize the requirements of the current statute: "(1) whether the expert is qualified, (2) whether the testimony is relevant, and (3) whether the testimony is reliable." 562 S.W.3d at 319 (emphasis added). Contrary to the dissents' claims, Hanshaw did not limit his arguments to Expert's general qualifications. After arguing that Expert was sufficiently qualified to offer expert opinions concerning the design of Crown's forklift, the next heading in Hanshaw's response explicitly argued that Expert's "opinions on stand-up forklift designs are reliable." Hanshaw began his reliability argument by quoting Wright's paraphrase of the requirements of §§ 490.065.2(2)(1)(b)
25 through (d): he argued that "[t]estimony is reliable if it is 'based on sufficient facts or data, reliable principles and methods and reliable application thereof.'" (Quoting Wright, 562 S.W.3d at 319). It is simply inaccurate for our dissenting colleagues to claim that "[n]owhere in his Response does Hanshaw assert that [Expert]'s opinions satisfy the reliability requirements of section 490.065.2(1)(a)- (d); these requirements are not even identified." (Emphasis omitted.) The dissents also contend that Hanshaw's opposition to the motion to exclude failed to explain how Expert's prior research work, or his investigations in this case, support his opinions. On the contrary, the manner in which Expert came to his opinions concerning the design of Crown's forklift was not a mystery to the circuit court. In § III.A, above, we have described and quoted excerpts from Expert's deposition and affidavit, which explain how his prior studies supported his design-defect opinions. Hanshaw provided all of those materials to the circuit court in opposing Crown's exclusion motion. In addition, Hanshaw's suggestions in opposition explained the work Expert had done to formulate his opinions in detail, with appropriate record citations: For this case, [Expert] has conducted or reviewed . . . Performance testing of forklifts, including the lateral and longitudinal acceleration of forklifts in operation during backing and steering. Further, [Expert] has conducted or reviewed Testing to evaluate the acceleration and speeds during forklift collision. [Expert] has conducted or reviewed testing for Evaluation of egress times from stand-up forklifts. [Expert] has analyzed speeds and accelerations of an RC-5500, the model of lift that is the subject of the pending matter. [Expert] has compared that data to accelerations and speeds from data obtained from Crown and from inspecting the subject lift. [Expert] compared all such data to the video of the actual incident involving Mr. Hanshaw.
26 [Expert] has inspected the facility at the location of the incident; inspected the subject forklift; reviewed all depositions, including the depositions of Crown employees, representatives, and expert witnesses; reviewed 135 photographs of the site and of the subject forklift; created a 3D model of the site of the incident; created a 3D model of the subject forklift; created speed analysis of the forklift during the actual event relying on video footage of the collision; and performed safety engineering analysis of the Crown forklifts relying on design engineering principles assessing the foreseeable failure and effects modes. [Expert] has analyzed Crown accident data reported by Crown and used this information in developing his opinions. [Expert] has partially based his opinions on in this case, the data obtained through OSHA of fatal accidents and injuries attributed to operation of forklifts, which note that seventy- six percent of all lower limb injuries of operators of stand-up forklifts are attributable to the operator's lower limb being inadvertently outside the operator's compartment. Moreover, Hanshaw's response to the motion to exclude explained that Expert's opinion that "a latching door on the subject forklift would improve its overall safety . . . was derived after obtaining a Crown RC3000 forklift and modifying it to include a door." This statement was supported with specific citations to the portions of Expert's deposition in which he described the egress- time testing he had conducted to assess the forklift industry's claim that a rear compartment door would hinder operator exit in the event of a stability accident. (To be clear, Hanshaw's response to the motion to exclude cited to specific numbered paragraphs from his Additional Statement of Uncontroverted Material Facts in Opposition to Summary Judgment, which was filed simultaneously; Hanshaw's statements of uncontroverted fact in turn cited to specific passages of Expert's deposition by page and line number. While the deposition references were not literally contained in Hanshaw's response to the motion to exclude, the effect is the same.)
27 The dissenting judges also contend that Expert's design-defect opinions suffer from the same "analytical gap" which we found disqualifying in Gebhardt v. American Honda Motor Co., 627 S.W.3d 37 (Mo. App. W.D. 2021). Gebhardt is plainly distinguishable, however. In Gebhardt, an expert opined that an all- terrain vehicle (or "ATV") suffered from a design defect, based in part on a manufacturer's recall. The recall addressed the risk that, over time, water could infiltrate a throttle mechanism, causing the ATV "to fail to return to idle" if the water froze. 627 S.W.3d at 45 (emphasis added). In the Gebhardt case, the expert claimed that the plaintiff's ATV experienced sudden acceleration due to the immediate effect of liquid water on the throttle mechanism. Id. Thus, the expert in Gebhardt relied on the manufacturer's recall to support his opinion, even though the manufacturer's recall involved a different failure mode, occurring over a different time span, producing a different outcome. In addition, in Gebhardt the expert's opinion was based on his assumption that water had splashed up into an area near the ATV's throttle mechanism, and then further assumed that this water came into contact with the throttle mechanism itself – with no evidence that such water infiltration had actually occurred. Id. at 45-46. Unlike in Gebhardt, in this case Expert did not speculate as to the circumstances of Hanshaw's injury, or as to the features of Crown's forklift which caused that injury. Expert conducted a detailed accident reconstruction based on an inspection of the site where the accident occurred and of the forklift Hanshaw was operating; review of video footage of the collision; and review of the depositions of Crown employees and experts. Expert constructed a three-
28 dimensional model of the accident site and the forklift, and calculated the speed, and the rates of acceleration and deceleration, of the forklift immediately prior to the accident. Based on this analysis, Expert concluded that Hanshaw had not attempted to jump from the truck, and had not stuck out his foot to try to "fend off" the pole he was approaching. Instead, Expert concluded that "[i]t's the deceleration and the lateral acceleration of the forklift at the same time" that caused Hanshaw to lose his balance, and caused his foot to come out of the operator compartment – a mechanism of injury which Expert contends would have been defeated by the addition of a compartment door. As Judge Thomson asserts, it may be "a contested factual issue" whether Hanshaw's injury occurred in this manner, and whether a compartment door would have prevented that injury; but those contested factual issues are for a fact-finder to decide, not for the court to decide on a motion to exclude expert testimony (or on a motion for summary judgment). As this Court has emphasized, the circuit court's role in addressing a motion to exclude expert testimony is not to judge the persuasiveness of the expert's opinions, or "to serve as a replacement for the adversary system." Ingham v. Johnson & Johnson, 608 S.W.3d 663, 701 (Mo. App. E.D. 2020). Instead, "'[v]igorous 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.'" Id. at 702 (quoting Daubert v. Merrell Dow Pharm., Inc., 509 U.S. 579, 596 (1993)). For present purposes, it suffices to note that there is no "analytical gap" in Expert's opinions between the claimed defect in the forklift's design and the injury Hanshaw suffered.
29 IV. In his briefing, Hanshaw also argues that Expert was competent to opine that the use of bumpers on Crown's forklift presented a safer design alternative. During his deposition, however, Expert testified that "I don't know that I have an opinion in that area," when he was asked whether bumpers should be added to Crown's forklift instead of a door. He also testified that he was "not sure" whether or not a bumper would have prevented Hanshaw's injuries. Expert also did not identify any prior research or testing he had conducted concerning the safety effects of adding bumpers to a stand-up forklift like the Crown RC5500. Given Expert's testimony, and his lack of experience with forklift bumpers, the circuit court acted well within its discretion in excluding Expert's opinion that the Crown forklift was defective for lack of a rear bumper. Hanshaw's discovery responses suggested that Expert might also provide opinions concerning the necessity and adequacy of warnings on Crown's forklift. During his deposition, however, Expert testified that he was not opining that the forklift was defective due to the lack of adequate warnings, and Hanshaw does not challenge the exclusion of any warnings-related opinions on appeal. We therefore have no basis upon which to question the circuit court's conclusion that Expert was not entitled to give warnings-related opinions. Finally, we note that Expert testified in his deposition that he believed Crown's stand-up forklifts were not appropriate for use in warehouse settings with loading docks like the one where Hanshaw was working, and that Crown should offer its customers other forms of material handling equipment as an alternative. Hanshaw does not seek to defend the admissibility of that opinion on appeal, and we consider the point abandoned.
30 V. In his final Point, Hanshaw contends that the circuit court erroneously granted summary judgment on his prayer for punitive damages. The circuit court's exclusion order and judgment reflect, however, that the court did not address Crown's alternative motion for partial summary judgment on punitive damages. Moreover, Hanshaw argued in the circuit court both that the summary-judgment evidence justified the submission of punitive damages, and that a ruling on this issue was premature pending further factual development. In these circumstances, we decline to address this issue, which the circuit court never reached. Conclusion Hanshaw presented an expert witness who had substantial experience studying and testing the performance and safety of stand-up forklifts. The opinion expressed by Hanshaw's expert – that Crown's forklift was unreasonably dangerous based on its lack of a rear door – was supported by his prior research work, and by his in-depth investigation of the circumstances surrounding Hanshaw's accident. Assessment of the credibility and probative value of that opinion was an issue for a jury to decide at trial – not a question for the circuit court to decide in pre-trial motions practice. The circuit court abused its discretion in concluding that Hanshaw's expert was unqualified, and that his design defect opinion concerning the lack of a door was unreliable. The circuit court's order excluding Hanshaw's expert from testifying, and its grant of summary judgment to Crown based on the exclusion order, are reversed. The
31 case is remanded to the circuit court for further proceedings consistent with this opinion. ________________________ Alok Ahuja, Judge Chief Judge Gabbert, and Judges Hardwick, Pfeiffer, Mitchell, Martin, Witt, Ardini, and Sutton concur. Judges Chapman and Thomson dissent in separate opinions.
