18 MEMORANDUM OPINION
19 ZAMORA, Judge. 1 {1} Plaintiff Jessica Sanders appeals from the district court’s judgment on a
2 jury’s verdict in favor of Defendants, arguing that the district abused its discretion
3 by denying her pretrial motion to exclude the testimony of Defendants’ expert
4 concerning the severity of the impact of a low-speed motor vehicle collision on the
5 human body. We affirm.
6 BACKGROUND
7 {2} Plaintiff sued Defendants Margery Pruett and her father, Tom Pruett, for
8 injuries she claims to have suffered to her head, neck, and back when Defendant
9 Margery Pruett rear-ended Plaintiff’s vehicle at a low speed while Plaintiff was
10 stopped at a traffic signal. Defendants retained Ronald Feder, a civil engineer and
11 accident reconstructionist, as an expert “to evaluate the [likely] severity of the
12 impact, the type of occupant motion that would be expected in this type of collision
13 based on simple physics and crash tests” and to present the jury with “crash tests of
14 similar severity” and “the resulting occupant movement.” Plaintiff moved to
15 exclude Feder arguing that he was not qualified to offer expert testimony on
16 biomechanical issues and that his testimony would be unreliable, misleading, and
17 of no assistance to the jury because it lacked a sound basis. Defendants opposed
18 the motion. At the motion hearing, Plaintiff also objected to the admission of the
19 photographs depicting the condition of the vehicles after the collision, arguing that
20 they were unfairly prejudicial.
2 1 District Court’s Order Denying Plaintiff’s Motion
2 {3} The district court denied Plaintiff’s motion in a written order issued after a
3 hearing. The court found that Feder is an expert in accident reconstruction, a field
4 that “includes low[-]speed collisions, occupant movement, severity and human
5 volunteer testing results in low[-]speed rear-end collisions[,] . . . the impact of low-
6 speed collisions on the human body and how the human body would likely react
7 inside a vehicle.” The court’s order included Feder’s background experience with
8 “the impact of low-speed collisions on the human body, including both
9 participating in [volunteer] testing and reviewing tests.” It explained the nature and
10 scope of Feder’s analysis and proposed testimony as including: “the severity of the
11 collision or delta-V”; the movement of the occupant in the vehicle “that would be
12 expected in this type of collision based on simple physics and crash test[s]”; and
13 occupant movement resulting from crash tests of similar severity. The court
14 concluded that Feder’s training and background and his examination of pictures of
15 Plaintiff’s vehicle and inspection of the damage to Defendant’s vehicle gave Feder
16 “knowledge and experience that would assist the jury in understanding the likely
17 speed of the collision, the amount of force exerted on the human body by the
18 accident and the likely type of movement that would have occurred to the occupant
19 inside the vehicle based upon delta-V forces.” The district court also found that as
3 1 long as a proper foundation for the photographs of the vehicles was laid at trial,
2 they would be admissible.
3 Feder’s Qualifications
4 {4} Defendants conceded that Margery Pruett was negligent, leaving the jury to
5 decide whether that negligence caused Plaintiff’s claimed injuries and damages.
6 Dr. Michael Freeman provided an affidavit in support of Plaintiff’s motion to
7 exclude Feder’s testimony, and his deposition testimony was read into the record at
8 trial. Dr. Freeman essentially disagreed with Feder’s opinions, was critical of
9 Feder’s reliance on human volunteer crash studies, and was adamant that Feder
10 was actually expressing a medical opinion for which he was not qualified.
11 {5} Feder’s résumé, provided before trial and admitted at trial as an exhibit,
12 listed his educational background, professional licenses, work experience,
13 specialized training and continuing education, professional organizations and
14 honors, and his presentations on low-speed collisions. Feder’s résumé identified
15 training programs, conferences, certification courses where he received training in
16 biomechanics of frequently claimed injury areas, performance of low-speed crash
17 testing and analysis, biomechanical analysis, delta-V (speed change) data and
18 comparison with crash test data, collision trauma biomechanics, and analysis of
19 low-speed collisions biomechanics.
20 Feder’s Trial Testimony
4 1 {6} Feder testified at trial that he has twenty-five years of experience as an
2 accident reconstruction specialist and has received accreditation through the
3 Accreditation Commission for Traffic Accident Reconstruction (ACTAR), has
4 taken a number of specialized courses in accident reconstruction, and is familiar
5 with peer-reviewed publications involving low-speed, rear-end motor vehicle
6 accidents. Feder explained accident reconstruction to the jury. He further explained
7 that accident reconstruction of low-speed collisions includes an analysis of vehicle
8 dynamics and occupant motion within the affected vehicle.
9 {7} Feder described the type of testing he has conducted on low-speed collisions
10 and his evaluation of those collisions and their injury potential, particularly
11 occupant movement in the vehicles in these collisions. He also described his
12 personal participation as a subject in low-speed crash testing. Feder testified about
13 his training in crash testing through the Texas Association of Accident
14 Reconstruction Specialists (TAARS) and the Society of Accident
15 Reconstructionists (SOAR). He is a member of both organizations, among others.
16 His training through TAARS and SOAR consisted of the practical application of
17 biomechanics, low-speed crash tests, and analysis. Feder explained to the jury his
18 simple definition of biomechanics as the evaluation of forces acting on the human
19 body. He clarified that he should not be called a “biomechanical engineer” because
20 he is an accident reconstructionist who has some expertise, training, and
5 1 experience in biomechanics. On cross-examination, Feder explained that there is
2 no clear line between accident reconstruction and biomechanics as there are things
3 that are done in accident reconstruction that cross over into biomechanics. Feder
4 testified that he has been qualified to give opinion testimony in state district courts
5 and federal district courts on the subject of low-speed impacts, vehicle dynamics,
6 and occupant motion.
7 {8} Feder opined that the severity of this collision is related to the change in
8 speed of Plaintiff’s vehicle, and based on the evidence and his education, training,
9 and experience, he further opined that the change in speed of Plaintiff’s vehicle
10 was between two and one-half miles per hour to five miles per hour. Assuming this
11 speed change, and assuming that the occupant was restrained and had a headrest,
12 Feder opined that within a reasonable degree of probability, there was no
13 mechanism of injury to the occupant.
14 {9} Feder inspected Defendants’ vehicle but was unable to inspect Plaintiff’s
15 vehicle because it was unavailable. Feder’s lack of access to Plaintiff’s vehicle did
16 not affect his opinion. He explained that the severity of a crash is measured by the
17 change in speed, or the delta-V, as that is what “really causes injury”. He further
18 explained how he determined the speed change. He discussed the use of all
19 published crash tests as part of the analysis that helped him evaluate and narrow
20 down the window to determine the speed change.
6 1 {10} Using published graphics, Feder showed the jury examples of occupant
2 movement relative to the vehicle seat in low-speed, rear-end collisions. He also
3 showed the jury videos of human subject testing at various speed changes. Feder
4 explained the concept of “rebounding,” which is when “the movement of the
5 vehicle forward causes the occupant to move rearward, relative to the
6 vehicle, . . .then the seat tends to try to spring back and so there’s some rebound of
7 the occupant forward.” He also testified that at a speed change of two and one-half
8 miles per hour to five miles per hour, he would not expect the occupant of the front
9 vehicle to strike their head on the steering wheel of their vehicle, as Plaintiff
10 claimed. He discussed peer-reviewed literature comparing the severity of collisions
11 and the severity of impacts that people endure while engaging in everyday
12 activities.
13 {11} Feder then testified about peer-reviewed studies concerning the potential for
14 injury to occupants in a rear-end collision similar to the case at hand. He explained
15 that the peer-reviewed literature suggests that vehicle occupants can tolerate a
16 change in speed of five miles per hour or less and opined based on the evidence,
17 his education, training, and experience that within a reasonable degree of
18 probability, there was no mechanism for injury with a speed change of two and
19 one-half miles per hour to five miles per hour as a result of a rear-end collision,
20 assuming the occupant is restrained and has a headrest.
7 1 {12} The jury returned a verdict for Defendants. On appeal, Plaintiff argues, as
2 she did below, that Feder’s testimony was inadmissible because it did not meet the
3 requirements for admitting expert testimony set forth in Rule 11-702 NMRA and
4 the case law interpreting it, and that the district court’s decision to admit this
5 testimony “was severely prejudicial to [P]laintiff’s case, justifying reversal and a
6 new trial.” She also argues that the district court’s decision to admit photographs of
7 the vehicles was contrary to Rule 11-403 NMRA and was “prejudicial error.” For
8 the first time on appeal, Plaintiff also argues that the photographs were cumulative
9 evidence and were confusing or misleading to the jury.
10 STANDARD OF REVIEW
11 {13} We review a trial court’s decisions to admit or exclude evidence, including
12 expert testimony, for an abuse of discretion. State v. Alberico, 1993-NMSC-047,
13 ¶ 58, 116 N.M. 156, 861 P.2d 192. An abuse of discretion occurs where “the trial
14 judge’s action was obviously erroneous, arbitrary, or unwarranted” or is “clearly
15 against the logic and effect of the facts and circumstances before the court.” Id. ¶
16 63.
17 DISCUSSION
18 {14} The admissibility of expert testimony is governed by Rule 11-702, which
19 provides as follows:
20 A witness who is qualified as an expert by knowledge, skill, 21 experience, training, or education may testify in the form of an 8 1 opinion or otherwise if the expert’s scientific, technical, or other 2 specialized knowledge will help the trier of fact to understand the 3 evidence or to determine a fact in issue.
4 Id.; see Parkhill v. Alderman-Cave Milling & Grain Co. of N.M., 2010-NMCA-
5 110, ¶ 11, 149 N.M. 140, 245 P.3d 585 (noting that our Supreme Court has
6 explained that “Rule 11-702 establishes three prerequisites for admission of expert
7 testimony: (1) experts must be qualified; (2) their testimony must assist the trier of
8 fact; and (3) their testimony must be limited to the area of scientific, technical, or
9 other specialized knowledge in which they are qualified.” (internal quotation marks
10 and citation omitted).
11 {15} Plaintiff argues that Feder’s testimony fails all three requirements and that
12 the district court “abdicated its gatekeeping duty by failing to analyze how Feder’s
13 testimony satisfied the three-part test for admissibility.” We disagree. While the
14 district court’s order did not separately analyze each of the rule’s requirements in
15 discussing the admissibility of Feder’s testimony, the transcript of the motion
16 hearing reflects the district court’s understanding of its function and the
17 significance of the decision to be made. In its order denying Plaintiff’s exclusion
18 motion, the district court sets forth the bases for the court’s admissibility
19 determination, which comports with the law. On this record, we cannot say that the
20 district court abused its discretion in denying Plaintiff’s motion to exclude Feder’s
21 testimony.
9 1 The District Court Did Not Abuse Its Discretion
2 {16} Plaintiff describes the “crux of this case” as “whether accident
3 reconstructionists can testify as experts in biomechanical engineering about
4 injuries to persons in motor vehicle crashes.” Her central argument is that Feder’s
5 expertise makes him qualified him to testify only about how a collision occurred
6 and that Feder should not have been allowed to testify about the likely effect on a
7 person occupying a vehicle rear-ended at a low speed because only an expert in
8 biomechanics or medicine is qualified to give such opinions. She appears to
9 assume that only a person holding a degree or certification in biomechanics or
10 medicine is qualified to give such testimony. Plaintiff complains in particular about
11 Feder’s testimony that “there was no ‘mechanism of injury’ in a crash like this.”
12 According to Plaintiff, “[e]ven if Mr. Feder qualified as an expert in accident
13 reconstruction, that did not establish his expertise in the ‘relevant field’ of
14 biomechanics and his testimony regarding the lack of ‘mechanism of injury’
15 clearly exceeded the scope of his qualifications as an accident reconstructionist.”
16 To the extent Plaintiff relies on the disagreement of her own expert with Feder’s
17 methods and opinions, she provides no authority to support the argument that this
18 required exclusion of Feder’s testimony. We therefore assume that no such
19 authority exists. See Curry v. Great Nw. Ins. Co., 2014-NMCA-031, ¶ 28, 320 P.3d
10 1 482 (“Where a party cites no authority to support an argument, we may assume no
2 such authority exists.”).
3 {17} As noted previously in laying out Feder’s trial testimony, his qualifications
4 and foundation were presented to the district court and confirmed in that testimony.
5 His trial testimony, particularly concerning the mechanism of injury, confirmed
6 that Feder did not exceed the limits of his qualifications and the foundation
7 presented to the district court. As discussed below, under our precedents it was not
8 necessary for Feder to have a degree in biomechanics, since the prerequisites of
9 Rule 11-702 were satisfied by his education, training, and experience.
10 {18} The jury heard testimony from both Feder and Dr. Freeman, and it was for
11 the jury to weigh the evidence and to accept or reject the expert testimony of Feder
12 and Dr. Freeman in whole or in part. See Chapman v. Jesco, Inc., 1982-NMCA-
13 144, ¶ 3, 98 N.M. 707, 652 P.2d 257 (“The fact[-]finder may reject expert opinion
14 evidence in whole or in part.”).
15 Both Parties’ Reliance on Baerwald v. Flores
16 {19} Both Plaintiff and Defendants rely on Baerwald v. Flores, 1997-NMCA-
17 002, 122 N.M. 679, 930 P.2d 816, in support of their respective arguments. In
18 Baerwald, this Court held that the trial court did not abuse its discretion in
19 determining that an expert witness with a graduate degree in engineering and
20 practice in the field was qualified to testify as an expert in biomechanics in a case
11 1 involving a motor vehicle collision and “possessed knowledge and experience that
2 would assist the jury in understanding the biomechanical aspects of th[e] case.” Id.
3 ¶ 10 (citing Rule 11-702). We characterized as “proper testimony” expert witness’s
4 opinion “on the amount of force exerted on the human body by the accident
5 expressed in terms of G-forces” based on “his study of biomechanics and
6 engineering” and his extrapolation of information “based on pictures of the
7 vehicles and the amount of damage done by the accident.” Id. ¶ 11. We concluded
8 that expert witness’s trial testimony, which included an opinion about whether the
9 collision at issue was capable of producing injury of the type claimed by the
10 plaintiff, see id. ¶ 18, was limited to “his area of expertise, that is, the effects of
11 forces on the human body[.]” Id. ¶ 15.
12 {20} The expert witness’s qualifications, in that case, did include “a bachelor’s
13 degree and a master’s degree in mechanical engineering with emphasis in
14 biomechanical engineering.” Id. ¶ 9. The plaintiff argued that expert witness’s
15 failure to hold an engineer’s license disqualified him from testifying as an expert
16 witness in any engineering field. Id. ¶¶ 8, 9. This Court noted that an expert
17 witness “may be qualified on foundations other than licensure [pursuant to Rule]
18 11-702.” Baerwald, 1997-NMCA-002, ¶ 9. In concluding that the trial court did
19 not abuse its discretion “in determining that [the expert witness] was qualified to
20 testify as an expert in biomechanics[,]” we cited cases from our Supreme Court
12 1 noting the trial court’s “wide discretion to determine whether [a] witness is
2 qualified to testify as an expert” and that “no set criteria can be laid down to test
3 [the] qualifications of [an] expert.” Id. ¶ 10.
4 {21} Plaintiff distinguishes Baerwald by arguing that the expert in that case had
5 both a bachelor’s degree and a master’s degree in mechanical engineering with an
6 emphasis in biomechanical engineering. Plaintiff argues that, unlike the experts in
7 Baerwald, Feder is not a biomechanics expert and is not qualified to testify about a
8 lack of mechanism of injury based on vehicle speeds and photographs showing
9 damage to the vehicles resulting from the collision.
10 {22} Defendants argue that the backgrounds of the Baerwald expert and Feder are
11 comparable. It is clear that the testimony elicited from defense counsel limited
12 Feder’s opinion to his area of expertise—accident reconstruction and the effects of
13 forces on the human body. Contrary to Plaintiff’s argument, there was no opinion
14 testimony about the causation of Plaintiff’s specific injuries as a result of this
15 motor vehicle accident.
16 {23} Plaintiff also cites to various out-of-jurisdiction authorities in support of her
17 arguments. Because we find Baerwald controlling, we need not consider outside
18 authorities. See Gulbransen v. Progressive Halcyon Ins. Co., 2010-NMCA-082,
19 ¶ 13, 148 N.M. 585, 241 P.3d 183; see also Rule 12-405(C) NMRA (stating that a
20 formal Court of Appeals opinion is controlling authority).
13 1 {24} The district court’s decision is also supported by our decision in State v.
2 Vigil, 1985-NMCA-110, ¶ 17, 103 N.M. 643, 711 P.2d 920, where we held that an
3 accident reconstructionist could testify about the movement of bodies within a
4 vehicle provided that he had the specialized knowledge, education, and experience
5 to do so. We rejected the defendant’s contention that expertise in accident
6 reconstruction “has no bearing” on the “ability to give an expert opinion as to the
7 movement of bodies within the vehicle.” Id. ¶¶ 13, 17. We held that the trial court
8 did not abuse its discretion in determining that “the field of accident reconstruction
9 requires specialized knowledge in a number of fields,” the accident
10 reconstructionist “was qualified as an expert pursuant to his knowledge,
11 background[,] training[,] . . . [and] wealth of experience,” which included “training
12 and knowledge of physics and engineering[.]” Id. ¶¶ 14, 16. On the qualification
13 issue, we held:
14 The trial court determined that the testimony of an accident 15 reconstructionist would aid the jury and that [the accident 16 reconstructionist] was qualified to give an expert opinion as to the 17 movement of bodies within the vehicle. In considering the 18 foundational information elicited from the witness, the trial court was 19 justified in finding the witness qualified to testify as to the movement 20 of bodies. Accordingly, we affirm the trial court’s admission of the 21 testimony of the state’s accident reconstructionist. The court does not 22 today decide that every “accident reconstructionist” will automatically 23 be qualified to testify as to the movements of human bodies within a 24 motor vehicle. Rather, the court rules that an accident 25 reconstructionist shown to be possessed of the education and 26 experience necessary to form an opinion on such movement may 27 properly be admitted to testify. 14 1 Id. ¶ 17 (emphasis added).
2 {25} In view of the foregoing, we see no basis for concluding that the district
3 court abused its discretion in determining that Feder was qualified to testify as an
4 expert concerning the severity of the collision, the likely movement of a person
5 inside the vehicle resulting from a collision such as the one at issue here, and the
6 likelihood that the occupant of a vehicle would sustain injuries of the type Plaintiff
7 claims as a result of a low-speed vehicle accident. The record supports the district
8 court’s determination that Feder’s testimony was admissible and that Feder’s trial
9 testimony was limited to his area of expertise. As in Baerwald and Vigil, Feder’s
10 testimony about the likely severity of the collision and the type of occupant motion
11 expected in this type of collision was admissible based on his extensive experience,
12 knowledge, background, and training, despite his lack of a degree in biomechanics.
13 {26} Plaintiff’s arguments that Feder’s opinions lack a reliable basis also provide
14 no basis for concluding that the district court abused its discretion in denying
15 Plaintiff’s motion to exclude his testimony. Plaintiff’s contention that the district
16 court must make a reliability determination on the record relies on federal cases
17 that are not controlling. In any event, Plaintiff’s contention that Feder’s testimony
18 was not reliable and would not assist the jury also relies primarily on Plaintiff’s
19 assumption about the qualifications necessary to give the opinions at issue and the
20 criticisms of Plaintiff’s expert of Feder’s qualifications and the studies on which he 15 1 relied. We are satisfied that the record contains evidence of the data and materials
2 upon which Feder relied for his opinions, which include peer-reviewed
3 publications discussing tests of low-speed, rear-end collisions and occupant
4 movement in such collisions.
5 The Photographs of the Motor Vehicles Were Properly Admitted Into 6 Evidence
7 {27} Plaintiff argues that the photographs of the motor vehicles involved in the
8 collision were inadmissible under Rule 11-403 because she conceded that the
9 accident occurred at a low speed, and, therefore, argues that the photographs
10 constituted “needless[] present[ation of] cumulative evidence.” Plaintiff also
11 argues that the photographs misled the jury into thinking that the minimal amount
12 of property damage meant there was no injury. The photographs were relevant to
13 Feder’s testimony. See Rule 11-401(A) NMRA (stating that the evidence only
14 needs to have a “tendency to make a fact more or less probable than it would be
15 without the evidence”). Because of the unavailability of Plaintiff’s vehicle four
16 years after the motor vehicle accident, it was necessary for Feder to rely on those
17 photographs in formulating his opinion.
18 {28} While the photographs’ depiction of the minimal damage to the vehicles is
19 counter to Plaintiff’s theory of the case, that does not make the photographs
20 unfairly prejudicial. Rule 11-403 allows for the exclusion of evidence only “if its
16 1 probative value is substantially outweighed by a danger of . . .unfair prejudice . . .
2 or needlessly presenting cumulative evidence[,]” among other reasons. Id.
3 (emphasis added); see State v. Hogervorst, 1977-NMCA-057, ¶ 46, 90 N.M. 580,
4 566 P.2d 828 (stating that the mere fact that competent evidence may tend to
5 prejudice a party is not grounds of exclusion of that evidence). The district court
6 did not abuse its discretion in admitting those photographs into evidence.
7 CONCLUSION
8 {29} Based on the foregoing, we conclude that district court did not abuse its
9 discretion in denying Plaintiff’s motion to exclude the expert testimony of Feder or
10 in the admitting the photographic evidence. We therefore affirm the district court’s
11 judgment.
12 {30} IT IS SO ORDERED.
