MATTHEW F. LEITMAN, District Judge.
This action arises out of an automobile accident between Plaintiff Angela Fields and Defendant Pierre Octavius Ashford that occurred on I-96 in Milford, Michigan. Fields' Ford Edge crashed into the back of Ashford's semi-truck shortly after Ashford pulled his truck from the shoulder into Fields' lane of travel. The central dispute between the parties is: what caused the accident? Fields says that Ashford caused the wreck by pulling into her lane and leaving her "no time at all to avoid [the] collision." (Fields Resp. Br., ECF No. 82, PageID.2337.) Ashford counters that he is not to blame because Fields had enough time to see his truck and to avoid the accident by braking and/or changing lanes.
Fields has retained accident reconstructionist Gary McDonald to support her causation theory. Ashford and Defendants Corr Transport, Inc. and Dakota Lines, Inc. have moved to exclude McDonald's opinions on the ground that his opinions do not rest upon a reliable foundation. (See Mot. to Exclude, ECF No. 81.) The Court will grant Defendants' motion.
McDonald's deposition testimony makes clear that he cannot reliably support Fields' causation theory. Indeed, McDonald admitted that he did not conduct any analysis that would allow him to "say" that Fields' "didn't have enough time" to avoid the accident. (McDonald Dep. at 35, ECF No. 81-1, PageID.2258.) Moreover, McDonald's expert report and the remainder of his deposition testimony demonstrate that he did not perform a reliable evaluation of the crash and that none of his causation opinions rest upon a reasonable foundation. His expert report is one page and lists conclusions without any causation analysis, and his deposition testimony revealed that he did not employ any analytical methodology, much less a reliable one. Therefore, for all of these reasons, the Court
The accident between Fields and Ashford occurred on May 25, 2016. Immediately prior to the accident, Ashford had stopped his semi-truck on the shoulder of I-96. (See Ashford Dep. at 37, ECF No. 71-2, PageID.1592.) Ashford then pulled back into the right lane of traffic at a speed of roughly 20-to-25 miles per hour. (See id. at 45, PageID.1600.) Fields was driving in that same lane. (See Fields Dep. at 43, ECF No. 71-3, PageID.1695.) Shortly after Ashford re-entered the highway, Fields crashed into the rear of Ashford's semi-truck. (See id. at 45-46, PageID.1697-98.) Both parties have engaged expert witnesses to support their contention that the other party is at fault for the crash.
Fields' proposed accident-reconstruction expert is McDonald. McDonald is the President of Magnetic North Consulting, and he is a former officer with the Michigan State Police. (See McDonald Dep. at 7-10, ECF No. 81-1, PageID.2251-2252.) He is also a member the Michigan Association of Traffic Accident Investigators and the International Association of Accident Reconstruction Specialists. (See id. at 9-10, PageID.2252.)
Fields retained McDonald in June of 2016. (See id. at 17-18, PageID.2254.) Thereafter, McDonald inspected Fields' car and reviewed the following documents:
(McDonald Expert Rpt., ECF No. 81-1, PageID.2246.)
On June 5, 2018, McDonald submitted his expert report. (See id.) In that report, he opines that Ashford "was the cause of [the] crash." (Id., PageID.2246-2247.) But the report contains no analysis whatsoever to support or explain that conclusion. Instead, the report — which consists of a mere 329 words and less than a single full page of text — simply lists a handful of facts related to the accident and then states McDonald's conclusion that Ashford caused the crash. In full, the report states as follows:
(Id., PageID.2246-2247.)
On June 4, 2019, McDonald appeared for a deposition in this action. He testified that he had reached the following conclusions: "Mr. Ashford failed to yield, he was driving below the minimum speed for commercial vehicles on the freeway and he took away Ms. Fields' right-of-way." (McDonald Dep. at 24, ECF No. 81-1, PageID.2255.) Based upon these conclusions, McDonald opined that Ashford was "a hundred percent" at fault for the accident. (Id. at 26, PageID.2256.)
During McDonald's deposition, Ashford's counsel asked McDonald to identify any evidence that Ashford left Fields no time to avoid the accident. (See id. at 34-36, PageID.2258.) In response to those questions, McDonald identified only Fields' own testimony that Ashford's truck "jumped right out in front of her." (Id. at 35, PageID.2258.) He then admitted that, apart from Fields' version of events, he had "no evidence" that Ashford had, in fact, "jumped" in front of Fields. (Id.) More importantly, McDonald admitted that his own work and analysis did not allow him to "say" that Fields "didn't have enough time" to avoid the accident. (Id.) And McDonald further conceded that he could not explain why Fields did not brake, did not swerve, and/or did not slow down before the crash. (See id. at 34, PageID.2258.) McDonald may not have been able to explain why Fields did not brake, swerve, or slow down because his analysis did not account for "perception-reaction time" and because he did not "factor in perception time."
McDonald's deposition testimony also revealed that he had done only limited work before reaching his conclusions. More specifically, McDonald acknowledged that apart from reviewing the five pieces of evidence listed in the bullet points above (in Section (I)(B)) and inspecting Fields' vehicle, he did not review any other evidence and did not do any modeling or testing before reaching his opinions and issuing his expert report:
(Id. at 20-22, PageID.2254-2255.) In addition, McDonald testified that he did not perform a "crush analysis," a "scene or grade analysis," or a "speed of impact" analysis related to the accident. (Id. at 22, 34, PageID.2255, 2258.) Nor did he ever conduct any analysis "to calculate the Ford Edge's speed." (Id. at 29, PageID.2257.) McDonald further admitted that he "never examined" Ashford's truck, never "made any conclusions specifically regarding the truck," and never rendered "an opinion as to the speed of [Ashford's] lane change" based on his "scientific" or technical "expertise." (Id. at 30, 32-33, PageID.2257-2258.) Finally, McDonald acknowledged that he did not "rely on any scholarly articles or treatises" in reaching his opinions. (Id. at 24, PageID.2255.)
Long after McDonald reached his opinions and issued his report, he did some additional work related to the accident. For instance, two days prior to his deposition — and nearly a full year after he issued his report containing his causation opinion — McDonald completed some handwritten mathematical calculations.
(Id. at 36-39, PageID.2258-2259.)
Later during McDonald's deposition, Fields' counsel returned to the topic of McDonald's handwritten calculations. Like the colloquy between defense counsel and McDonald concerning the handwritten calculations, the exchange between Fields' counsel and McDonald about the calculations — reproduced verbatim below — is difficult to understand. That difficulty stems in no small part from the fact that, as the italicized portions of the colloquy below indicate, some of the key questions are imprecise and McDonald did not directly or clearly answer certain important questions:
(Id. at 47-49, PageID.2260-2261; emphasis added.)
McDonald also prepared a set of drawings at some unidentified point during his work.
Finally, McDonald conducted a computer calculation that he labeled "Skid Distance to Stop From Known Speed and Drag Factor."
Defendants moved to exclude McDonald's expert opinion testimony on June 26, 2019. (See Mot. to Exclude, ECF No. 81.) In support of that motion, Defendants argued, among other things, that the Court should exclude McDonald's testimony because "his own unsupported speculative beliefs ... are not the product of reliable principles and methods." (Id., PageID.2196.) Fields filed a response to the motion on July 17, 2019. (See Fields Resp. Br., ECF No. 82.)
Pursuant to Local Rule 7.1(f)(2), the Court concludes that oral argument is not necessary and would not aid its decision on Defendants' motion.
Defendants argue that McDonald's proposed testimony does not satisfy the standards for the admission of opinion testimony set forth in Federal Rule of Evidence 702. That rule provides:
FRE 702.
Under this rule, district courts have "broad discretion as [] `gatekeeper[s]' to determine the admissibility" of expert testimony. Pride v. BIC Corp., 218 F.3d 566, 578 (6th Cir. 2000). In assessing proposed expert testimony, a district court must "determine whether [the] evidence `both rests on a reliable foundation and is relevant to the task at hand.'" Newell Rubbermaid, Inc. v. Raymond Corp., 676 F.3d 521, 527 (6th. Cir. 2012) (quoting Daubert v. Merrell Dow Pharm., Inc., 509 U.S. 579, 597 (1993)).
In Daubert, the Supreme Court stressed that there is no "definitive checklist or test" that a district court must apply when considering the reliability of expert testimony. Daubert, 509 U.S. at 590. Yet, at the same time, the Supreme Court identified "several factors that a district court should consider when evaluating the scientific validity [and reliability] of expert testimony, notably: the testability of the expert's hypotheses (whether they can be or have been tested), whether the expert's methodology has been subjected to peer review, the rate of error associated with the methodology, and whether the methodology is generally accepted within the scientific community." Pride, 218 F.3d at 577 (citing Daubert, 509 U.S. at 593-94). In addition, "Daubert and its progeny make clear that `[p]roposed [expert] testimony must be supported by appropriate validation.'" Id. at 578 (quoting Daubert, 509 U.S. at 591). As the Sixth Circuit recognized following Daubert, "[t]he party seeking to have testimony admitted bears the burden of showing that the expert's findings are based on sound science, and this will require some objective, independent validation of the expert's methodology; the expert's bald assurance of validity is not enough." Smelser v. Norfolk S. Ry., 105 F.3d 299, 303 (6th Cir. 1997) (internal quotation marks omitted), abrogated on other grounds by Morales v. Am. Honda Motor Co., Inc., 151 F.3d 500 (6th Cir. 1998).
The Daubert "factors, while perhaps most apt in evaluating a purely scientific discipline, can also apply in evaluating non-scientific fields that are `technical' or `specialized' in nature." United States v. Mallory, 902 F.3d 584, 593 (6th Cir. 2018) (quoting Kuhmo Tire Co., Ltd. v. Carmichael, 526 U.S. 137, 149-53 (1999)). However, these factors may not be useful in evaluating the reliability of some types of expert testimony, and thus applying the "factors [is] not mandatory in every case." Id. For instance, the Daubert factors may be "unhelpful" where an expert's opinion testimony is based entirely upon his personal knowledge and "practical experiences." First Tenn. Bank Nat. Ass'n v. Barreto, 268 F.3d 319, 335 (6th Cir. 2001); see also Wood v. Wal-Mart Stores E., LP, 576 F. App'x 470 (6th Cir. 2014) (same).
Finally, "nothing in either Daubert or the Federal Rules of Evidence requires a district court to admit evidence that is connected to existing data by the ipse dixit of the expert." Gen. Elec. Co. v. Joiner, 522 U.S. 136, 146 (1997). In the end, "[t]he questions of what factors to apply and what conclusions to draw about an expert's reliability are entrusted to the district court's discretion." Mallory, 902 F.2d at 593; see also Kuhmo Tire, 526 U.S. at 141 ("[W]hether Daubert's specific factors are, or are not, reasonable measures of reliability in a particular case is a matter that the law grants the trial judge broad latitude to determine.").
As the "proponent" of McDonald's causation opinion testimony, Fields must "establish its admissibility by a preponderance of proof." Nelson v. Tenn. Gas Pipeline Co., 243 F.3d 244, 251 (6th Cir. 2001). More specifically, Fields "bears the burden of showing, among other things, that [McDonald's] opinion is based on a reliable foundation." Harms v. United States, 2017 WL 3642202, at *9 (E.D. Mich. Aug. 24, 2017).
According to Fields, McDonald's causation opinions are reliable because McDonald showed how the "empirical evidence ... makes crystal clear that [Ashford] left [Fields] no time at all to avoid [the] collision." (Fields Resp. Br., ECF No. 82, PageID.2337.) That is simply not true. Indeed, McDonald testified that he did not conduct any analysis that would allow him to "say" that Fields "didn't have enough time" to avoid Ashford's semi-truck. (McDonald Dep. at 35, ECF No. 81-1, PageID.2258.) McDonald further acknowledged that he could not explain why Fields did not brake before she collided with Ashford's truck, could not explain why she did not swerve to avoid the truck, and could not explain why she did not slow down in any way. (See id. at 34, PageID.2258.) Moreover, McDonald never determined how fast Fields was travelling at the time of the crash, and he never factored in "perception-reaction time" when determining whether Fields had an opportunity to stop before she hit Ashford's truck. (Id. at 29-30, PageID.2257.) As all of this makes clear, McDonald had no reliable basis on which to testify that Ashford left Fields with no time to avoid the collision. Thus, the Court will not permit McDonald to offer opinion testimony that Ashford caused the accident by leaving Fields with no opportunity to avoid hitting his truck when he merged into her lane.
Fields has also failed to establish that any other aspects of McDonald's causation opinions are based upon a reliable foundation. The fundamental flaw with McDonald's opinions is that they do not rest upon any discernible methodology at all, much less a methodology that may be deemed reliable. As described above, in McDonald's report, he identified some background facts related to the accident and then simply asserted that Ashford's driving caused the accident. His report contains no reasoning or analysis at all. Then, during McDonald's deposition, he failed to provide a chain of technical or scientific reasoning or analysis to explain how Ashford's driving caused the crash.
The decision in Reynolds v. Freightliner, LLC, 2006 WL 5249744 (E.D. Ky. June 21, 2006), is instructive. In Reynolds, the plaintiff sought damages for fatal injuries suffered by her husband when he was "ejected from the cab of the truck he was driving." Id. at *1. Plaintiff alleged, among other things, that the "design and manufacture of both the seatbelt and the door latch of the tractor" were defective. Id. In support of that argument, the plaintiff sought to introduce the expert testimony of an accident reconstructionist, Stephen Chewning. See id. at *2. In a "one and a half page" initial expert report, Chewning sought to explain how the decedent was ejected from the truck. Id.
The defendant moved to exclude Chewning's expert testimony, and the district court granted that motion. The court concluded that Chewning's expert opinions were not admissible because Chewning had failed to identify any "particular methodology" that he used "to actually reach his opinions" and had failed to "supply[] the reasons/bases underlying his conclusions." Id. at *4 (internal emphasis removed). In relevant part, the court held that:
Id. at **8-9 (emphasis added).
The court in Neal v. Fort, 2017 WL 455499 (M.D. Tenn. Jan. 20, 2017), reached the same conclusion. Neal was a "personal injury case centered on a car wreck." Id. at *1. "The parties fundamentally disagree[d] as to the cause of the accident." Id. In support of defendant's version of events, defendant sought to introduce the expert testimony of David G. Huskey, an accident reconstructionist. See id. Huskey thereafter provided an expert report in which he "provide[d] a step-by-step breakdown of how he believe[d] the accident occurred." Id.
The district court granted plaintiff's motion to exclude Huskey's opinion testimony on the ground that his report failed to identify his methodology:
Id. at *4 (emphasis added).
McDonald's causation opinions suffer from the precise flaws that led the courts in Reynolds and Neal to exclude the proposed causation opinions. Like the expert in Neal, McDonald has not "describe[d] how his experience led to his conclusions," nor has he "explain[ed] how he reliably applied his experience to the facts of the case." Id. And, like the excluded expert in Reynolds, McDonald has not presented "any identifiable method of reasoning" and he has failed to "explain how, given the facts and data he relied upon, he reach[ed] the conclusions outlined in his report" and deposition. Reynolds, 2006 WL 5249744, at *8. Thus, as in Neal and Reynolds, "the absence of a methodology" makes McDonald's "testimony patently unreliable" and inadmissible. Id. at *9; see also Volkswagen of Am., Inc. v. Ramirez, 159 S.W.3d 897, 904-06 (Tex. 2004) (requiring exclusion of causation testimony by accident reconstruction expert who "never explain[ed] how [certain] tests supported his conclusions" and did not "explain how any of the research or tests he relied on support his conclusion").
There are additional reasons to question the reliability of the manner in which McDonald reached his conclusions. For instance, Fields has not shown that McDonald's causation testimony satisfies any of the Daubert factors. Fields has not presented evidence that McDonald applied generally accepted causation-analysis methods, that McDonald used techniques that had been tested or whose error-rates had been determined, or that McDonald used any peer-reviewed approaches to causation analysis. Nor has Fields presented evidence that McDonald's work in this case has been validated in any way. Fields' failure to show that McDonald's testimony satisfies the Daubert factors, while not dispositive, further weighs against admission of McDonald's testimony. See, e.g., Mike's Train House, Inc. v. Lionel, L.L.C., 472 F.3d 398, 407-08 (6th Cir. 2006) (excluding proposed expert testimony where, among other things, the expert's "methodology had never been tested, subjected to peer review, possessed a known or potential rate of error, or enjoyed general acceptance"); Pride, 218 F.3d at 578 (holding that "[t]he failure of [plaintiff's] experts to test their hypotheses in a timely and reliable manner or to validate their hypotheses by reference to generally accepted scientific principles as applied to the facts of this case renders their testimony on [causation] unreliable and therefore inadmissible under Daubert and Federal Rules of Evidence 702 and 104").
In addition, it appears that McDonald's work fell below the standard of practice employed by the International Association of Accident Reconstruction Specialists ("IAARS"), a group to which McDonald belongs. In order to become a member of IAARS, an applicant must submit an "example of accident reconstruction work" that the applicant has completed. (ECF No. 81-1, PageID.2313.) That "example" must include a "scale diagram, photographs, measurements, [and] all calculations done to arrive at speeds, angles, [and] distances." (Id.) Yet in this case, McDonald reached his causation opinion and issued his report before he had done much of this work (if he completed it at all). (See McDonald Dep. at 24-25, ECF No. 81-1, PageID.2255-2256.)
Finally, Fields' own submissions to the Court appear to suggest that McDonald's work on this case may fall short of the work that he has done on other cases. In Fields' words, McDonald "has [an] extensive background in [] accident reconstruction including vehicle inspection, geometric construction, scale drawings of collisions and scenes, scene examination, speed determinations, time distance determinations, impact analysis, lamp examination, and conservation of linear momentum." (Fields Resp. Br., ECF No. 82, PageID.2335.) Yet here, McDonald performed few, if any, of these analyses before he issued his report containing his opinions, and that lends further support to the Court's conclusion that his opinions were not based on reliable methods. See, e.g., Mahoney v. USA Hockey, Inc., 138 F. App'x 804 (6th Cir. 2005) (affirming exclusion of expert witness where, among other things, proposed expert did not "attempt to replicate the incident, perform any manner of accident reconstruction or conduct any relevant technical or scientific testing").
Fields counters that McDonald's proposed causation testimony is based on reliable methods and is therefore admissible. The Court does not find her arguments to be persuasive.
Fields argues that McDonald's work is reliable because he "made numerous mathematical calculations to check and support his conclusion[]" that Ashford caused the accident by leaving Fields no time to avoid his truck. (Fields Resp. Br., ECF No. 82, PageID.2336; emphasis added.) There are several problems with this argument. First, as noted above, McDonald admitted that his work does not permit him to reliably say that Fields did not have enough time to avoid the wreck. Second, Fields never offers a coherent explanation as to how McDonald's calculations show that Ashford left Fields without enough time to avoid the accident. Indeed, as set forth above (in Section (I)(C)(4)), McDonald's testimony concerning the calculations is not comprehensible in any meaningful way. Third, Fields vastly overstates the extent of the mathematical calculations. McDonald made a limited number of calculations that appear on one and one-quarter pages of paper. (See ECF No. 81-1, PageID.2300-2301.) And McDonald admitted that a sizeable portion of those calculations — including the calculations based upon Fields' purported speed of 92 miles per hour — address circumstances that, according to McDonald, did not exist at the time of the accident. (See McDonald Dep. at 38-39, ECF No. 81-1, PageID.2259.) Fourth, many of McDonald's calculations were completed nearly a year after McDonald drafted his expert report and reached the conclusion that Ashford was "a hundred percent" at fault for the crash. (See id. at 25, PageID.2256.) Finally, Fields has not cited any evidence that the calculations McDonald performed are the types of calculations that other experts in the accident reconstruction field rely upon when making causation determinations.
Finally, Fields argues that the Court should find McDonald's causation opinions to be reliable because they are like the opinion testimony that the Sixth Circuit deemed admissible in Dilts v. United Grp. Servs., LLC, 500 F. App'x 440 (6th Cir. 2012). In Dilts, the expert inspected the defective crane at issue, conducted a generally accepted photographic measurement analysis, and used a computer program to identify damage to the crane:
Id. at 445-46 (emphasis added).
Unlike the expert admitted in Dilts, McDonald did not visit the scene of the accident, did not inspect Ashford's truck, and did not create any models, simulations, or animations related to the accident before reaching his opinion. McDonald is not in the same position as the expert in Dilts, and Dilts therefore does not compel the conclusion that McDonald's opinions are based on reliable methods.
Fields also argues that the Sixth Circuit's decision in Clark v. Chrysler Corp., 310 F.3d 461, 470-71 (6th Cir. 2002), supports admission of McDonald's testimony. The Court disagrees. In Clark, the Sixth Circuit held that the district court did not abuse its discretion in admitting opinion testimony from an accident reconstructionist. But there was no showing in Clark, as there has been here, that the accident reconstructionist failed to employ any recognizable methodology. Thus, Clark does not compel the admission of McDonald's testimony. See Reynolds, 2006 WL 5249744, at *10 (explaining that Clark does not support admission of opinion testimony by accident reconstructionist who does not use a clear methodology). In any event, the holding of Clark was simply that the district court did not abuse its discretion in admitting the accident reconstructionist's testimony; the decision does not stand for the additional proposition that it would have been an abuse of discretion to exclude that testimony. The Court declines to admit McDonald's testimony pursuant to Clark.
For all of the reasons explained above, the Court concludes that Fields has failed to demonstrate that any of McDonald's opinions concerning the cause of the accident rest upon a reliable foundation. Accordingly, the Court will exclude McDonald's proposed causation testimony in its entirety.
As noted above, as one component of McDonald's overall causation opinion, McDonald testified that Ashford was driving "below the minimum speed [established by the Michigan Motor Vehicle Code] for commercial vehicles on the freeway." (McDonald Dep. at 24, 26, 46, ECF No. 81-1, PageID.2255, 2256. 2261.
The Court notes that there is an additional and independent ground for excluding McDonald's testimony that Ashford was traveling below the minimum required speed: that testimony is not based upon scientific or technical principles or knowledge, is unnecessary, and is not helpful to the jury. McDonald did not calculate Ashford's speed nor perform an analysis to determine whether Ashford was traveling below the minimum speed. (See id. at 32, PageID.2257.) Instead, McDonald simply compared (1) Ashford's testimony that he entered the freeway at 20-to-25 miles per hour to (2) the minimum freeway speed established under the Michigan Motor Vehicle Code. (See id. at 26-28, 32, PageID.2256, 2257.) That comparison does not require any specialized training or knowledge. Indeed, every juror will be able to make the very same comparison — of Ashford's admitted speed to the Motor Vehicle Code's minimum freeway speed — without any assistance from McDonald. Simply put, there is no basis or need for opinion testimony by McDonald that Ashford was driving below the minimum speed. The Court would therefore exclude McDonald's testimony that Ashford was travelling below the minimum required speed on this alternative basis as well.
For all of the reasons stated above, the Court
The Court previously denied without prejudice Defendants' motion for summary judgment pending the Court's consideration of Defendants' motion to exclude McDonald's testimony. (See Order, ECF No. 80.) At that time, the Court told Defendants that it would "allow [them] to renew [their] motion for summary judgment" after the Court ruled on the admissibility of McDonald's testimony. (Id., PageID.2192.) If Defendants wish to file a renewed motion for summary judgment, they shall do so by no later than
