For the following reasons, the Court declines to exclude Plaintiff’s expert
Background
22
Plaintiff has brought this wrongful death action on his own behalf and on behalf of
23
all statutory beneficiaries of Decedent James Updike, Sr. (“Decedent”)—Plaintiff’s
24
father. (Doc. 1-2 at 13). Plaintiff alleges that Decedent was driving a 2019 Honda Talon

The parties have requested oral argument in this matter, but the Court denies this
request because the issues have been fully briefed and oral argument will not aid the
Court’s decision. See Fed. R. Civ. P. 78(b) (court may decide motions without oral
hearings); LRCiv 7.2(f) (same).

manufactured by Defendant and that it rolled over in the Imperial Sand Dunes in Glamis,
2
California on February 7, 2020. (Id. at ¶¶ 10-15). Plaintiff alleges that the Talon’s
3
rollover protection system (“ROPS”) failed when the rear bar at the top of the roll cage
4
directly behind and above the driver’s head snapped, causing the roll cage to buckle and
5
injure Decedent. (Id. at ¶¶ 16-17). The Talon’s original safety harnesses were replaced
6
with aftermarket Pro Armor harnesses by Plaintiff before the roll over. (Doc. 89-7 at 4).
7
Plaintiff brings claims for negligence, strict product liability, breach of express/implied
8
warranty and punitive damages against Defendant. (Doc. 1-2 at ¶¶ 20–52). To support
9
these claims, Plaintiff has retained several expert witnesses which Defendant now seeks
10
to exclude.
11
II.
Legal Standard
12
Rule 702 of the Federal Rules of Evidence tasks the trial court with a special
13
“gatekeeping” obligation to ensure that any expert testimony provided is relevant and
14
reliable. Daubert v. Merrell Dow Pharm., Inc., 509 U.S. 579, 589 (1999). A qualified
15
expert may testify based on their “scientific, technical, or other specialized knowledge” if
16
it “will assist the trier of fact to understand the evidence.” Fed. R. Evid. 702(a). An
17
expert may be qualified to testify based on his or her “knowledge, skill, experience,
18
training, or education.” Id. The expert’s testimony must also be based on “sufficient
19
facts or data,” be the “product of reliable principles and methods,” and the expert must
20
have “reliably applied the principles and methods to the facts of the case.” Id. at 702(b)–
21
(d). “Rule 702 should be applied with a ‘liberal thrust’ favoring admission.” Messick v.
22
Novartis Pharmaceuticals Corp., 747 F.3d 1193, 1197 (9th Cir. 2014) (quoting Daubert,
23
509 U.S. at 588).
24
Daubert’s general holding applies to an expert’s testimony based on “scientific”
25
knowledge, but also to testimony based on “technical” and “other specialized”
26
knowledge. Kumho Tire Co., Ltd. v. Carmichael, 526 U.S. 137, 141 (1999). Daubert
27
suggests a number of factors for courts to consider in discharging its gatekeeping
28
obligation; however, these factors do not apply to testimony that depends on knowledge
-2-
1
and experience of the expert, rather than a particular methodology. United States v.
2
Hankey, 203 F.3d 1160, 1169 (9th Cir. 2000) (citation omitted) (finding that Daubert
3
factors do not apply to a police officer’s testimony based on twenty-one years of
4
experience working undercover with gangs). Furthermore, “[t]he inquiry envisioned by
5
Rule 702” is “a flexible one.” Daubert, 509 U.S. at 594. “The focus . . . must be solely
6
on principles and methodology, not on the conclusions that they generate.” Id. The
7
proponent of expert testimony has the ultimate burden of showing that the expert is
8
qualified and that the proposed testimony is admissible under Rule 702. See Lust v.
9
Merrell Dow Pharm., Inc., 89 F.3d 594, 598 (9th Cir. 1996). The trial court is vested
10
with broad discretion deciding whether an expert is qualified to testify. See, e.g., General
11
Elec. Co. v. Joiner, 522 U.S. 136, 142 (1997); United States v. Espinosa, 827 F.2d 604,
12
611 (9th Cir.1987) (“The decision to admit expert testimony is committed to the
13
discretion of the district court and will not be disturbed unless manifestly erroneous”).
14
That the opinion testimony aids, rather than confuses, the trier of fact goes
15
primarily to relevance. See Temple v. Hartford Ins. Co. of Midwest, 40 F. Supp. 3d 1156,
16
1161 (D. Ariz. 2014) (citing Primiono v. Cook, 598 F.3d 558, 564 (9th Cir. 2010)).
17
Evidence is relevant if it has “any tendency to make a fact more or less probable than it
18
would be without the evidence and the fact is of consequence in determining the action.”
19
Fed. R. Evid. 401. However, an expert witness, “cannot give an opinion as to her legal
20
conclusion, i.e., an opinion on an ultimate issue of law.” United States v. Diaz, 876 F.3d
21
1194, 1197 (9th Cir. 2017) (internal citations omitted); see also Fed. R. Evid. 704.

III.
Discussion
23
Defendant seeks to exclude six of Plaintiff’s purported experts: Dr. Andrew
24
Rentschler, Dr. James Mason, Dr. Michael Markushewski, Mr. Mark Cannon, Dr. Daniel
25
M. Wolfe, and Mr. Jamie Winkler. (Docs. 86, 88, 89, 91, 92 93). Plaintiff has responded
26
to each of Defendant’s Motions arguing that their experts should not be excluded as “this
27
is not a case where the severe and sparingly imposed remedy of pre-trial exclusion of any
28
of Plaintiff’s experts is justified under Daubert.” (E.g., Doc. 101 at 2). The Court will
-3-
1
address the Parties’ arguments for and against the exclusion of each expert in turn,
2
beginning with Dr. Markushewski as some of the other experts’ opinions rely on his
3
expert opinion.
4
A.
5
Defendant seeks to exclude Dr. Markushewski’s opinion that the Decedent was
6
“properly wearing the available seat belt restraints at the time of the Subject Accident”
7
under Rules 403, 702 and Daubert. (Doc. 89 at 3). Defendant essentially argues that Dr.
8
Markushewski’s opinion is not based on reliable principles and methods as required by
9
Rule 702(c) because: (1) he did not perform any testing to validate his opinion, and (2) he
10
did not exclude other potential causes based on the evidence before him. (Id. at 9–10).
11
Defendant also argues that Dr. Markushewski’s opinions are “built on inadmissible
12
hearsay” and should be excluded. (Doc. 119 at 2). Plaintiff argues in response that Dr.
13
Markushewski’s opinions are supported by eyewitness testimony and that testing
14
conducted by Dr. Markushewski show’s that a Talon occupant of Decedent’s height and
15
weight, wearing an identical helmet with identical harness settings, would not have struck
16
his head on the roof of a Talon that did not sustain a ROPS failure and collapsed roof.
17
(Doc. 103 at 5, 12). Plaintiff also argues that Dr. Markushewski did not need to conduct
18
testing to identify “load marks” on the Talon’s harness. (Id. at 12). After discussing the
19
relevant portions of Dr. Markushewski’s opinions, the Court will address each of
20
Defendant’s arguments for exclusion in turn.
Dr. Markushewski
21
In Dr. Markushewski’s expert report authored on May 23, 2022, he concludes that
22
(1) the roll cage failed and the roof panel and roll cage tubing collapsed downward
23
toward the driver occupant space, (2) Decedent’s helmet was impacted by the collapsing
24
roof and roll cage structure creating a mechanism for his ultimately fatal injuries, and (3)
25
the roll cage structure is defectively designed and unreasonably dangerous and not suited
26
for its intended purpose. (Doc. 89-8 at 10). In his supplemental rebuttal report authored
27
on April 12, 2023, Dr. Markushewski further concludes that (1) Decedent “was wearing
28
an appropriate helmet and was properly wearing the available seat belt/harness restraint”
-4-
1
and (2) the seat belt “provided the restraint necessary to prevent his neck injury in this
2
protectable rollover incident if the roll cage does not collapse. The roll cage collapse into
3
the occupant space compromised [Decedent’s] ride-down space and was proximate to,
4
and the mechanism for, his ultimately fatal neck injuries.” (Doc. 89-9 at 16). Dr.
5
Markushewski bases these opinions, in part, on an inspection of the Talon conducted in
6
Phoenix, AZ on February 9, 2023. (Id. at 4).
7
Important here, Dr. Markushewski states that he inspected the Talon’s restraint
8
system. (Id. at 8). The Talon’s restraint system is a “4-point, 3 inch wide manually
9
adjusted harness manufactured by ProArmor.” (Id.) The restraint system consists of:
10
11
12
13
14
15
16
17
a manually adjustable lap belt with a center lift-lever locking mechanism
with a secondary Velcro attachment tab. The shoulder harnesses are sewn
onto the lap belts such that the lift lever will simultaneously latch the lap
belts and shoulder harnesses with one center latch. A central cross strap
connects the shoulder harnesses together. The upper section of shoulder
harness is wrapped around a cross bar behind the seat and held in place
with a 3-bar slide adjuster. The inboard and outboard lap belt anchors are
mounted to brackets on the inboard and outboard sections of the vehicle
frame.
(Id.) Dr. Markushewski states that the “as-found” adjustment positions of the lap belts
and shoulder harnesses on the Talon were documented and that the lap belt and shoulder
18
harness adjustments had been moved from Decedent’s adjusted position to accommodate
19
Gregory Updike, Decedent’s son, who drove the vehicle back to the camp after the
20
21
22
23
incident. (Id. at 9). Gregory Updike testified to this and stated that he knew the restraints
were tight because of the way Decedent was sitting restrained against them after the rollover and because he had to loosen the restraints a great deal to get them on and then
retighten it. (Doc. 103-1 at 38, 25–26). Dr. Markushewski examined the restraint system
24
and found that the lap belt “displayed a full width linear abrasion evident approximately
25
12 inches from the outboard lap belt anchor.” (Doc. 89-9 at 9). He also found that the
26
27
28
lap belt displayed a full width linear abrasion evident at approximately 12 inches from the
inboard lap belt anchor. (Id. at 10).
Dr. Markushewski also conducted a “surrogate fit check” test where he had a
-5-
1
surrogate who was 5’ 10-1/2” tall and weighed 227 pounds go through various clearance
2
and restraint system measurements. (Id. at 12). Dr. Markushewski and his surrogate
3
conducted an “inversion test” with a new Pro Armor 3 inch wide, 4-point restraint system
4
in a machine which allows for testing of full-size vehicles in a rotational manner under a
5
1G environment. (Id. at 13). Based on this test, Dr. Markushewski states that the test
6
Defendant’s experts Michael Carhart and Eddie Cooper performed was flawed as they
7
did not adjust the lap belt to where the “visually obvious dynamic loading marks left by
8
[Decedent] during the incident” were. (Id. at 15). He also concluded that “the seat belt
9
provided the restraint necessary to prevent [Decedent’s] neck injury in this protectable
10
11
rollover incident if the roll cage d[id] not collapse.” (Id. at 16).
Dr. Markushewski has also been deposed in this matter.
He discussed his
12
conclusion that the lap belt displayed linear abrasion marks evident approximately 12
13
inches from the outboard and inboard lap belt anchors. (See Doc. 89-7). When asked
14
about the characterization of the abrasion marks, Dr. Markushewski stated that they were
15
“light abrasions as you would expect in a crash like this.” (Id. at 7). When asked how
16
much force was calculated to have applied to the webbing in pounds, Dr. Markushewski
17
stated that he did not calculate the pounds of force Decedent would have experienced
18
during the rollover—but estimates it at four or five Gs. (Id.) Dr. Markushewski also
19
stated that friction creates broken fibers when the belt is loaded, but that these marks can
20
occur from the webbing of the belt being in a position for a long period of time. (Id.) Dr.
21
Markushewski did not attempt to re-create these marks through a “drop test,” but he did
22
do an inversion test with a surrogate. (Id. at 7–8). Dr. Markushewski admitted that the
23
outboard abrasion mark could be a “set mark,” a mark which does not have broken fibers,
24
but confirmed that the inboard side abrasion mark looked like an impact mark and stated
25
that the outboard side was likely both a set mark and abrasion mark based on his
26
experience. (Id. at 10). He further stated that this mark “looks like a dynamic loading
27
mark. It’s more than a set mark, which is just kind of a light fold. This is much more
28
than that.” (Id.)
-6-
1
1.
Dr. Markushewski’s Opinion is Admissible
Defendant argues that Dr. Markushewski’s opinion on the abrasion marks “is
2
3
nothing more than [his] own ‘say so,’ and should be excluded.”
(Doc. 89 at 8).
4
Defendant essentially argues that Dr. Markushewski should have, but did not, conduct a
5
dynamic drop test to determine whether the “dynamic abrasion marks” arose under
6
similar circumstances to the accident at issue. (Id.) Because he did not conduct this test,
7
Defendant argues that Dr. Markushewski’s opinion is not the product of reliable
8
principles and methods and should therefore be excluded under Rule 702 and Daubert.
9
(See id.) Plaintiff argues in response that these marks are visible to the naked eye and
10
obvious from the discoloration at that part of the harness. (Doc. 103 at 9). He also
11
argues that the inversion testing Dr. Markushewski conducted was sufficient. (Id. at 11–
12
12).
13
Dr. Markushewski has a Bachelor of Science in Mechanical Engineering
14
Technology. (Doc. 103-2 at 23). His curriculum vitae states that he has worked on
15
crashworthiness issues, specifically, restraint systems since 1994. (Id. at 24). Indeed, Dr.
16
Markushewski conducted an “inversion test” and found that Decedent was wearing the
17
restraint system properly during the incident and that the roll cages collapse was the
18
mechanism for his fatal neck injuries. (Doc. 89-9 at 16). When asked about the abrasion
19
marks he found at the twelve-inch mark, Dr. Markushewski admitted that the outboard
20
abrasion mark could be a set mark, but confirmed that the inboard side abrasion mark
21
looked like an impact mark because there’s torn fibers inside these marks and stated that
22
the outboard side was likely both a set mark and abrasion mark—based on his
23
experience. (Doc. 89-7 at 10).
24
demonstrate the difference between a set mark and an abrasion mark with broken fibers,
25
Dr. Markushewski stated it wasn’t necessary as he “relied upon prior publications, my
26
own work and my experience to come up with that conclusion.” (Id. at 8).
When asked whether he conducted any testing to
27
The Court finds that Dr. Markushewski has extensive experience, as he states in
28
his CV, conducting research, design, testing and evaluating restraint systems. Based on
-7-
1
that experience, he is knowledgeable concerning the differences between set marks and
2
abrasion marks. This particular opinion depends on Dr. Markushewski’s knowledge and
3
experience, rather than a particular methodology; so, the Daubert factors do not apply to
4
this opinion. Hankey, 203 F.3d at 1169 (stating that the Daubert factors do not apply to
5
testimony that depends on knowledge and experience of the expert, rather than a
6
particular methodology). It is also permissible, as Plaintiff notes, that a qualified expert
7
may rely on their visual inspection of evidence to render an opinion. See Icon-IP Pty Ltd.
8
v. Specialized Bicycle Components, Inc., 87 F. Supp. 3d 928, 940 (N.D. Cal. 2015)
9
(finding that it is “a matter of common sense that a visual and manual inspection would
10
be one acceptable way for a mechanical engineer to assess the structural characteristics of
11
a bicycle seat.”); Fontem Ventures, B.V. v. NJOY, Inc., 2015 WL 12743861, at *7 (C.D.
12
Cal. Oct. 22, 2015) (noting that an “expert’s opinions as to certain uncomplicated
13
elements can be based on a visual inspection.”).
14
Moreover, Defendant’s argument goes to the weight of the evidence, not its
15
admissibility. See Johnson v. City of San Jose, 2023 WL 8852489, at *4 (N.D. Cal. Dec.
16
21, 2023) (“Defendants’ arguments as to the evidentiary support for [the expert]’s
17
opinions go to the weight of his testimony, rather than its admissibility.”) (citation
18
omitted); see also Wendell v. GlaxoSmithKline LLC, 858 F.3d 1227, 1237 (9th Cir. 2017)
19
(“Where, as here, the experts’ opinions are not the ‘junk science’ Rule 702 was meant to
20
exclude, the interests of justice favor leaving difficult issues in the hands of the jury and
21
relying on the safeguards of the adversary system—vigorous cross-examination,
22
presentation of contrary evidence, and careful instruction on the burden of proof[.]”).
23
This evidence “should be attacked by cross examination, contrary evidence, and attention
24
to the burden of proof [rather than] exclusion.” Primiano v. Cook, 598 F.3d 558, 564
25
(9th Cir. 2010).
26
Finally, the Court finds that Dr. Markushewski’s purported testimony is more
27
probative than prejudicial, so, the Court will not exclude his testimony under Rule 403.
28
Rule 403 states that the trial court “may exclude relevant evidence if its probative value is
-8-
1
substantially outweighed by a danger of one or more of the following: unfair prejudice,
2
confusing the issues, misleading the jury, undue delay, wasting time, or needlessly
3
presenting cumulative evidence.”
4
testimony is highly probative as it establishes how Decedent was injured as well as that
5
the design of the roll cage was defective. (Doc. 89-8 at 10). This probative value of Dr.
6
Markushewski’s testimony is also bolstered by the fact that Dr. Rentschler stated that he
7
is relying on Dr. Markushewski’s opinion to come to his own conclusion on the
8
mechanism of Decedent’s injury. (Doc. 86-8 at 4). Finally, although this evidence may
9
be somewhat prejudicial to Defendant’s case, “[v]irtually all evidence is prejudicial or it
10
isn’t material.” Old Chief v. United States, 519 U.S. 172, 193 (1997) (O’Connor, J.,
11
dissenting) (citations omitted). Any prejudice this evidence and testimony may hold is
12
outweighed by its probative value. See Fed. R. Evid. 403.

Fed. R. Evid. 403.
Here, Dr. Markushewski’s
Thus, the Court will not exclude Dr. Markushewski for not performing testing to
validate his opinion.
2.
Other Potential Causes
16
Defendant also argues that Dr. Markushewski should be excluded because he
17
failed to rule out other potential causes for the abrasion marks based on the evidence
18
before him. (Doc. 89 at 12 (citing Walsh v. LG Chem Am., 2021 WL 4859990, at *5–6
19
(D. Ariz. Oct. 19, 2021)).
20
rejecting alternative hypothesis using scientific methods and procedures and elimination
21
of those hypotheses must be founded on more than subjective beliefs or unsupported
22
speculation.” (Id. (citing Messick v. Novartis Pharms. Corp., 747 F.3d 1193, 1198 (9th
23
Cir. 2014)). Not so.
24
It also argues that an expert “must provide reasons for
This argument essentially relies on the differential diagnosis sub-body of Daubert
Differential diagnosis is “the
25
law which has been endorsed by the Ninth Circuit.
26
determination of which of two or more diseases with similar symptoms is the one from
27
which the patient is suffering, by a systematic comparison and contrasting of the clinical
28
findings.” Clausen v. M/V NEW CARISSA, 339 F.3d 1049, 1057 (9th Cir. 2003). “The
-9-
1
first step in the diagnostic process is to compile a comprehensive list of hypotheses that
2
might explain the set of salient clinical findings under consideration. The issue at this
3
point in the process is which of the competing causes are generally capable of causing the
4
patient's symptoms or mortality..” Clausen, 339 F.3d at 1057–58. The second step is for
5
the expert to “engage in a process of eliminating or ruling out the identified potential
6
causes.” Stanley v. Novartis Pharms. Corp., 11 F. Supp. 3d 987, 1001 (C.D. Cal. 2014)
7
“When an expert rules out a potential cause in the course of a differential diagnosis, the
8
‘expert must provide reasons for rejecting alternative hypotheses using scientific methods
9
and procedures and the elimination of those hypotheses must be founded on more than
10
subjective beliefs or unsupported speculation.’ ”
11
Clausen, 339 F.3d at 1058).
Messick, 747 F.3d at 1198 (citing
12
As stated above, Dr. Markushewski’s opinion regarding abrasion marks depends
13
on his knowledge and experience, rather than the use of scientific methods and
14
procedures; therefore, he does not need to provide reasons for rejecting alternative
15
hypothesis using scientific methods and procedures. Clausen, 339 F.3d at 1057–58. This
16
argument also goes to the weight of the evidence and not its admissibility—so, this
17
evidence “should be attacked by cross examination, contrary evidence, and attention to
18
the burden of proof [rather than] exclusion.” Primiano, 598 F.3d at 564. The Court
19
declines to exclude Dr. Markushewski’s because he did not chase alternate explanations
20
for the abrasion marks.
21
3.
Hearsay
22
Defendant also argues that Dr. Markushewski’s opinions are “built on
23
inadmissible hearsay.” (Doc. 119 at 2). The Federal Rules of Evidence clearly denote
24
that expert witnesses may rely on inadmissible evidence to form their opinion (including
25
hearsay) if experts in that particular field would rely on “those kinds of facts or data.”
26
Fed. R. Evid. 703; Carson Harbor Vill., Ltd. v. Unocal Corp., 270 F.3d 863, 873 (9th Cir.
27
2001) (“experts are entitled to rely on hearsay in forming their opinions.”). Not only
28
would other experts in this field rely on eyewitness testimony, but some of Defendant’s
- 10 -
1
experts have relied on Greg Updike’s testimony. (Doc. 89-4 at 6 (expert report of Dr.
2
Graeme Fowler)). Specifically, Dr. Graeme Fowler relied on Greg Updike’s testimony to
3
reconstruct decedents accident. (Id. at 7–12). In fact, one of Plaintiff’s experts, Dr.
4
Wolfe, criticized Dr. Fowler for relying “entirely on witnesses who did not see the
5
incident, with the exception of Greg Updike, who caught a split second of the incident in
6
his rear-view mirror.” (Doc. 92-2 at 11). So, because other experts have relied on this
7
“hearsay,” Dr. Markushewski is allowed to rely on the conversation between Dr. Jim
8
Mason and Gregory Updike—especially since Gregory Updike confirmed what Dr.
9
Mason told Dr. Markushewski when he was deposed, which is what Dr. Markushewski
10
actually relied on in his expert report. (Doc. 89-9 at 9).
11
In sum, the Court declines to exclude Dr. Markushewski from testifying.
12
B.
13
Defendant next argues that Dr. Rentschler’s opinions should be excluded because
14
(1) he relies on Dr. Markushewski’s opinion and is acting as a “conduit” for his opinions
15
and (2) Dr. Markushewski’s opinions are faulty.3 (Doc. 86 at 8, 11). Defendant seeks to
16
exclude Dr. Rentschler under Rules 403 and 702 as well as Daubert for his “unblinking”
17
reliance on Markushewski’s opinions. (Id. at 8). Plaintiff argues that, even though Dr.
18
Rentschler relies on Dr. Markushewski’s opinion, his opinion is still admissible as this
19
reliance does not provide a basis for exclusion. (Doc. 101 at 6, 8). Plaintiff also argues
20
that he can prove his claims without this evidence—which is an argument raised in the
21
parties’ summary judgement motions.4 (Id. at 8).
Dr. Rentschler
22
The opinions of multiple experts may be necessary in a complex case to establish a
23

“sole or primary reliance on the opinions of other experts raises serious reliability
9
questions.” In re ConAgra Foods, Inc., 302 F.R.D. 537, 556 (C.D. Cal. 2014). More

Toyota Motor Corp., 978 F. Supp. 2d at 1066 (citation omitted).
13
Here, Dr. Markushewski’s opinions were created for the purposes of litigation, so,
14
given increased scrutiny, the question is whether Dr. Rentschler is “merely acting as a
15
conduit” for Dr. Markushewski’s opinions.

Plaintiff retained Dr. Rentschler to opine on the “mechanism” of Decedent’s
injury. (Doc. 101 at 4). In his preliminary report, Dr. Rentschler concludes that:
1. On February 7, 2020, Mr. James Updike Sr. was driving a 2019 Honda
Talon on sand dunes in Glamis, California when the Talon pitched forward
over the top of a dune and rolled end-over-end before coming to rest on all
four wheels.
2. The roll cage failed and the roof panel and roll cage collapsed downward
toward the driver occupant space during impact with the sand dune.
3. Contact occurred between the top of Mr. Updike’s helmeted head and the
intruding roof structure/roll cage during the rollover event.
4. The injury mechanism responsible for Mr. Updike’s C2 nondisplaced
type II/III fracture of the dens involves localized hyperextension with
associated compression. This injury mechanism resulted from the contact
between Mr. Updike’s helmeted head and the intruding roof structure/roll
cage during the subject incident.
(Doc. 86-9 at 10) (emphasis added). The Court notes that Rentschler’s conclusions 1–3
- 12 -
1
are substantially similar to the conclusions that Dr. Markushewski came to, but his fourth
2
conclusion is unique. (See id.) To come to this conclusion, Dr. Rentschler reviewed
3
medical records, the inspection done by Dr. James Mason, Dr. Mason and Dr.
4
Markushewski’s written reports, “other available documents.” (Id. at 4–5). From his
5
review, he states the following opinion:

The loading paradigms experienced by Mr. Updike’s cervical spine during
the various phases of the subject incident were investigated in the context
of the mechanisms responsible for damage to the various tissues and the
constellation of injuries he presented with. As previously described, the
initial contact between the front of the nosed-down Honda and the sand
dune would have resulted in forward and upward motion of Mr. Updike’s
body relative to the occupant space in the Honda. As the four-point restraint
system retained Mr. Updike’s torso, his cervical spine loading paradigm
would primarily consist of cervical flexion and tension, inconsistent with
the mechanisms for his cervical spine injuries. Similarly, the inertial
loading of Mr. Updike’s cervical spine as the vehicle came to rest would
not be sufficient to cause injury. During the contact between the ROPS and
the sand (i.e. while inverted), Mr. Updike’s body would have accelerated
upward and toward his seatback. Mr. Updike’s cervical spine would have
experienced extension and tension until being contacted by the intruding
roof structure and possibly the head restraint in the Honda. In the absence
of contact between Mr. Updike’s head and the intruding roof structure/roll
cage, no significant injury mechanisms would be expected during this
phase.
The intruding roof structure/roll cage contacted Mr. Updike’s helmet,
facilitating a combination of compression and local hyperextension of the
upper cervical spine, with possible shear force of C1 on C2. The resulting
cervical motions and forces were sufficient to cause type III fracture of the
dens in combination with failure of the anterior longitudinal ligament and
widening of the C1-2 articulations as noted in the available diagnostic
studies.
(Id. at 9–10).
At his deposition, Dr. Rentschler testified that he became involved in this matter
because of Dr. Markushewski. (Doc. 86-8 at 3). Dr. Rentschler states that he was tasked
with addressing the biomechanical aspects of the case, which include: “look[ing] at the
injury that [Decedent] sustained, considering the injury mechanism, how that injury
- 13 -
1
occurred as a result of the incident and then, ultimately, what [were] any factors involved
2
in the actual injury and, ultimately, could it have been prevented based on our findings if
3
there was an issue with the vehicle.” (Id.) When asked what other experts he has relied
4
on, Dr. Rentschler stated that he is relying on Dr. Markushewski because “[h]e was the
5
one who inspected and analyzed the restraint system in this case and determined -- that
6
basically did the testing -- the inversion testing with respect to that to determine what the
7
clearance would have been for [Decedent] based on his interpretation of the settings for
8
the restraint system.” (Id. at 4). When asked what the opinions are that he has generated
9
himself, Dr. Rentschler testified that his opinions are that:
10
11
12
13
14
15
16
17
[Decedent’s] cervical injuries, certainly, the C2 odontoid fracture and
cervical spine injury at that level was the result of contact between the top
of his helmet and the roof of the subject Honda Talon during the rollover
event, that based on, again, the restraint system and Mr. Markushewski's
findings, that absent the deformation to the ROPS system sustained during
the incident rollover, that Mr. Updike would have had sufficient clearance
within the vehicle during the event to prevent any contact between his head
or helmet and the roof of the vehicle and that, therefore, absent deformation
or crush damage to the ROPS, that Mr. Updike would not have sustained
the cervical injuries that he did as a result of the incident.
(Id. at 7).
18
The Court finds that Dr. Rentschler is not acting as a conduit for Dr.
19
Markushewski. Dr. Rentschler can rely on Dr. Markushewski’s opinion as Rentschler’s
20
opinion builds upon Markushewski’s analysis and Markushewski’s testimony is
21
admissible.
22
Rentschler certainly references Dr. Markushewski’s expert opinion, he utilizes this
23
opinion to come to his own conclusion: that “[t]he injury mechanism responsible for
24
[Decedent’s] C2 nondisplaced type II/III fracture of the dens involves localized
25
hyperextension with associated compression. This injury mechanism resulted from the
26
contact between [Decedent’s] helmeted head and the intruding roof structure/roll cage
27
during the subject incident.” (Doc. 86-9 at 10). The Court finds that the relationship
28
between Dr. Rentschler and Dr. Markushewski’s is akin to a physician relying on a

opinion to come to his own opinion on the injury mechanism—an area which Dr.

Markushewski’s opinion as a reference point, the Court will not exclude his opinion.

(Doc. 86-8 at 3).
Since Dr. Rentschler is using

The Court also finds that the probative value of Dr. Rentschler’s testimony is not

outweighed by the danger of prejudice his reliance on Dr. Markushewski presents. As
12
stated above, an expert may rely on another expert’s opinion to establish their own
13
opinion. See In re Toyota Motor Corp., 978 F. Supp. 2d at 1066. There is no danger of

In sum, the Court declines to exclude Dr. Rentschler at this juncture.

21
Defendant next argues that Dr. Mason should be excluded as his opinions are
22
untested, inherently unreliable, and, therefore, inadmissible. (Doc. 88 at 11). It also
23
states that Mason has done no case specific testing at all. (Id. at 16). Plaintiff argues that
24
Dr. Mason’s opinion does not have to be supported by testing. (Doc. 102 at 8).
Dr. Mason
25
Plaintiff retained Dr. Mason to “assess the pre-drilled design of the ROPS bar and
26
tubing that failed during [Decedent’s] rollover.” (Doc. 102 at 6). Dr. Mason is a doctor
27
in “applied (fracture) mechanics.” (Id.) Dr. Mason concluded in his expert report that:
28
The ROPS was defective in design due to the introduction of a hole in the

underside of the rear cross bar and due to the use of thin-walled tubes in its
construction, i.e. tubes with too large of a diameter and too small of a wall
thickness. The aftermarket components attached to the rear crossmember
were foreseeable and likely increased the stress around the hole in the
crossmember by approximately 3-4%, much less than the hole itself.
(Doc. 88-6 at 5-6). Dr. Mason’s opinions are stated as follows:
To a reasonable degree of engineering certainty, I have formed the
following opinions.
1. The roll over protection system (ROPS or roll cage) in the Honda
deformed and fractured due to downward forces applied to the top.
2. Reportedly, the vehicle was going approximately 20-25 miles per hour
(mph) over soft sand dunes when it encountered a sloped drop-off of
approximately 15-25 feet and pitched forward, conditions that were
foreseeable and that the ROPS should have been designed to easily survive.
3. A fracture resulting in intrusion of the ROPS into the passenger
compartment from above occurred at a hole that was introduced into the
underside of the rear cross bar during manufacture. The location and size of
the hole resulted in the stress around the hole being approximately three
times higher than if the hole had not been introduced. Consequently, the
hole made the cross bar three times weaker.
4. The use of tubing that was approximately 2 inches in diameter with a
wall thickness of approximately 1116 inch introduced localized inelastic
tube buckling as a failure mode, and consequently weakened the ROPS
overhead structure, allowing the B-pillar support and the C-pillar support to
buckle, resulting in intrusion of the ROPS into the passenger compartment
from above during this incident.
5. The use of tubing that was approximately 2 inches in diameter with a
wall thickness of approximately 1116 inch resulted in a ROPS system that
could easily collapse when subjected to bending as a result of buckling
andlor impact, as it partially did in the left B and C pillars, resulting in
intrusion of the ROPS into the passenger compartment from above during
this incident.
6. The thin wall of the tubing allowed the left longitudinal bar to deform
and bend near its connection to the left B pillar, resulting in intrusion of the
ROPS into the passenger compartment from above during this incident.
(Id. at 3-4). Dr. Mason also states that:
The introduction of a hole in the bottom of the crossbar was a bad idea
from the start. Engineers are taught that holes create stress concentration
- 16 -
1
2
3
4
and then they are taught how to minimize the increased risk of failure that
such holes create. The introduction of the hole made the cross bar three
times weaker than it was without the hole. The logical alternative designs
include eliminating the hole or moving the hole to the top or side of the
tube. This is basic engineering.

Further destructive investigation is needed to determine whether the
collapse of the ROPS was due to manufacturing defect.
(Doc. 88-5 at 8). In sum, his opinion is that: “[t]he ROPS was defective in design due to
the introduction of a hole in the underside of the rear cross bar and due to the use of thin
walled tubes in its construction, i.e. tubes with too large of a diameter and too small of a
wall thickness.” (Id.)
During his deposition, Dr. Mason stated that he has “d[one] an estimate of the
force that occurred based on some of the numbers given by others in this case,
particularly, I want to say, Mr. Fowler.” (Doc. 88-7 at 3). He did not, however, conduct
testing to confirm what amount of force is required to produce the deformation on the
Talon’s roof or fracture the cross bar. (Id.) In fact, Dr. Mason has not done any testing
of his own in this matter; but he did calculate that the approximate force the Talon
endured during the roll-over was approximately 7,200–9,000 pounds of force given the
weight of the Talon and speed approximated by Mr. Fowler. (Id. at 3–4).
Here, Dr. Mason is certainly qualified as an expert. Fed. R. Evid. 702(a). He is a
20
doctor in “applied (fracture) mechanics.” (Doc. 102 at 6). He has also taught courses
21
related to “materials science and failure of materials.” (Doc. 88-5 at 2). He has also
22
23
24
25
26
27
28
conducted studies to evaluate the fracture of metals, plastics, and composites. (Id.)
Based on his education, training and experience the Court finds that Dr. Mason is a
qualified expert. Fed. R. Evid. 702. Dr. Mason was forthcoming in his deposition about
his expertise in this matter, admitting many areas, such as what conditions the ROPS
should be able to survive, injury causation, and “quasistatic tests” (tests where force is
applied at various points and measured), were outside of his expertise. (See Doc. 88-7).
Dr. Mason did calculate, in theory, that the Talon endured 7,200–9,000 pounds of force
- 17 -
1
given the weight of the Talon and speed Decedent was going which was approximated by
2
Mr. Fowler. (Id. at 3). While Dr. Mason did not perform any of his own testing, the
3
admissibility of expert testimony “does not depend on the expert personally performing
4
testing,” however. Speaks v. Mazda Motor Corp., 118 F. Supp. 3d 1212, 1219 (D. Mont.
5
2015) (citing Fed. R. Evid. 702).
6
Like Dr. Markushewski, much of Dr. Mason’s opinions and conclusion are based
7
on his knowledge and experience; meaning that the Daubert factors do not apply to his
8
testimony. See Hankey, 203 F.3d at 1169 (finding that Daubert factors do not apply to a
9
police officer’s testimony based on twenty-one years of experience working undercover
10
with gangs). Dr. Mason himself states that his opinions are based on his education,
11
background, knowledge, and experience in the fields of materials science, fracture
12
mechanics, and mechanical engineering. (Doc. 88-5 at 2). Based on the above, the Court
13
finds that Dr. Mason is qualified to testify on the failure of the Talon’s crossbar generally
14
and will not exclude his from testifying at this juncture.
15
16
Dr. Mason’s opinion is ripe for rigorous cross-examination, not exclusion. See
Primiano, 598 F.3d at 564.
17
D.
Mr. Cannon
18
Defendant next argues that Mr. Cannon should be excluded as his disclosure is
19
untimely and because he is not qualified to testify regarding the adequacy of warnings.
20
(Doc. 91 at 3). Defendant also argues that his testimony will not aid the jury. (Id. at 8).
21
Defendant states that it anticipates Mr. Cannon will testify that “(1) [Defendant] should
22
have mentioned and/or more fulsomely highlighted any safety risk associated with the
23
installation and placement of the certain aftermarket accessories (i.e., the lighted whip
24
and antenna) in the Talon’s Owner’s Manual” and that “(2) the flagpole bracket
25
information in the Owner’s Manual is ‘deficient,’ ‘not reasonable,’ not ‘appropriate,’ and
26
does not ‘follow [Dorris’] recommended format regarding warnings relative to safety.’ ”
27
(Id. at 3). Defendant argues that Mr. Cannon is really a case-in-chief expert as Plaintiff’s
28
Complaint includes “failure to warn” allegations in both the negligence and strict liability
- 18 -
1
counts. (Doc. 91 at 3 n.4).
2
Plaintiff argues that Mr. Cannon is qualified by both experience and training as a
3
“human factors expert” because he has a masters degree in advanced safety and
4
engineering management and has over 25 years of experience in forensic engineering and
5
investigates a wide variety of mechanical and safety issues. (Doc. 104 at 5–6). Plaintiff
6
does not address Defendant’s timeliness argument. (See Doc. 104). The Court will
7
review these arguments in turn.
8
Federal Rule of Civil Procedure 26(a)(2)(B) requires the parties to disclose the
9
identity of each expert witness “accompanied by a written report prepared and signed by
10
the witness.” Fed. R. Civ. P. 26(a)(2)(B). Expert disclosures must be made according to
11
the deadlines set by the Court. Id. at 26(a)(2)(D). A rebuttal expert may only testify after
12
the opposing party’s initial expert witness testifies. Lindner v. Meadow Gold Dairies,
13
Inc., 249 F.R .D. 625, 636 (D. Hawaii 2008). Specifically, rebuttal expert testimony must
14
address the “same subject matter” identified by the initial expert. Fed. R. Civ. P.
15
26(a)(2)(C)(ii); Lindner, 249 F.R.D. at 636.
16
Under Rule 16(f), a court may issue “any just orders” where “a party or party’s
17
attorney fails to obey a scheduling or pretrial order.” Fed. R. Civ. P. 16(f). The Ninth
18
Circuit has held that the purpose of Rule 16 is “to encourage forceful judicial
19
management.” Sherman v. United States, 801 F.2d 1133, 1135 (9th Cir. 1986). Whether
20
to issue sanctions under Rule 16(f) is left to the sound discretion of the district court. See
21
Ayers v. City of Richmond, 895 F.2d 1267, 1269 (9th Cir. 1990) (citing Ford v. Alfaro,
22
785 F.2d 835, 840 (9th Cir.1986)).
23
Plaintiff states that he retained Mr. Cannon to “rebut Dr. Fowler’s inference that
24
[Defendant’s] warnings were sufficient to inform Talon owners that the use of an
25
aftermarket mounting bracket or radio antenna might cause the Talon’s ROPS to break
26
and its roof to collapse during a slow speed rollover in soft sand.” (Doc. 104 at 2). The
27
Court’s Rule 16 Scheduling Order set the following deadlines: Plaintiff’s expert
28
disclosure deadline – May 22, 2022; Defendant’s expert disclosure deadline - September
- 19 -
1
27, 2022; Plaintiff’s rebuttal expert deadline - October 12, 2022.
2
Importantly, this order states that “[r]ebuttal experts shall be limited to responding to
3
opinions stated by initial experts.” (Id. at 3). The Court also extended the deadline for
4
the “disclosure of experts and completion of expert discovery” to July 28, 2023.
5
(Doc. 71).
(Doc. 10 at 3).
6
Mr. Cannon’s expert report, authored on December 6, 2022, states that the
7
“assignment and scope” of his engagement is to “evaluate and comment on the reports
8
submitted by Dr. Fowler and Dr. Dorris on behalf of American Honda. Specifically, I was
9
asked to address the issue of information and warnings provided on the Honda Talon and
10
the contrast between the findings in Drs. Fowler’s and Dorris’ reports.” (Doc. 104-
11
1 at 2). Mr. Cannon reviewed these reports (Id. at 3–6) and addressed his concerns with
12
them.
13
“regarding the warnings and labels provided by [Defendant] on the Talon with respect to
14
the specific subject matters that the warnings address” but that “[a]ntenna and flag pole
15
bracket mounting are not addressed in these warnings and the information about the
16
bracket, as cited by Dr. Fowler, does not comport with the warnings format extolled by
17
Dr. Dorris.” (Id.) Mr. Cannon concludes that:
18
19
20
21
22
23
24
25
26
27
28
(Id. at 7–8).
Mr. Cannon notes that he does not disagree with Dr. Dorris
Dr. Fowler criticizes [Decedent] for placing the Quick Light whip and the
Rugged Radio aerial antenna where they were found mounted to the Talon
because they compromised the strength of the cross-member and
“undoubtedly” applied a concentrated load, increasing the bending stresses.
Dr. Fowler is describing actions that are critical to safety. However, the
information in the manual upon which Dr. Fowler bas[e]s his opinion on
the mounting decision does not follow the methodology in putting forth
safety information in an explicit format that Dr. Dorris opines is adequate.
If the flag pole mounting information is as critical as Dr. Fowler
describes, then it needs to follow Dr. Dorris’ recommended format
regarding warnings relative to safety. And by Dr. Dorris’ reckoning, the
flagpole bracket information in the manual is deficient and not reasonable
nor appropriate.
(Id. at 8) (emphasis added).
Reviewing these opinions, the Court finds that Mr. Cannon is responding to
- 20 -
1
opinions stated by Defendant’s experts: Dr. Dorris and Dr. Fowler. Thus, the Court, in its
2
discretion, declines to exclude Mr. Cannon because that he is not a “case-in-chief expert
3
in rebuttal expert clothing.” (Doc. 91 at 1); Ayers, 895 F.2d at 1269.
4
Lastly, the Court finds that Mr. Cannon’s testimony is admissible because he is a
5
qualified expert, and his report contradicts or rebuts Dr. Fowler’s report; as the Court
6
found above. See Lindner, 249 F.R.D. at 636. Furthermore, his testimony is relevant as
7
his testimony will necessarily attack the credibility of Defendant’s experts and “it is the
8
jurors’ responsibility to determine credibility by assessing the witnesses and witness
9
testimony in light of their own experience.” United States v. Sine, 493 F.3d 1021, 1034–
10
35 (9th Cir. 2007) (internal citation omitted). So, the Court declines to exclude Mr.
11
Canon. Messick v, 747 F.3d at 1197. However, since Mr. Cannon is designated as a
12
rebuttal expert, he cannot testify in Plaintiff's case-in-chief or at all unless and until
13
Defendant’s experts testify as to the opinions for which he has been designated as a
14
rebuttal expert. See Lindner, 249 F.R.D. at 636.
15
E.
16
Next, Defendant seeks to exclude Mr. Wolfe on the basis that he (1) lacks the
17
knowledge, training, and experience required to render the opinions in his report, (2) he
18
merely restates Dr. Fowler’s opinions, and (3) he misstates the law by invading the
19
province of the jury and the Court. (Doc. 92 at 1). Defendant states that Plaintiff
20
retained Mr. Wolfe to “assume the role of Monday morning quarterback” and critique Dr.
21
Fowler’s accident reconstruction. (Doc. 92 at 4). Plaintiff argues that he retained Dr.
22
Wolfe to

25
26
27
28
Dr. Wolfe
rebut Dr. Fowler’s opinions by evaluating Dr. Fowler’s methodology of (1)
simply fabricating data (like the Talon’s speed) without any reliable
scientific basis; (2) relying solely on witnesses who admit to not seeing the
rollover or knowing anything about Jim’s path of travel and (3) using
measurements from what Dr. Fowler concedes is fundamentally a different
sand dune at the same general location two years after the fact and which
all agree has none of the same measurements or characteristics of the
subject dune.
- 21 -
1
(Doc. 105 at 2). Plaintiff also argues that he is entitled to offer rebuttal testimony under
2
Daubert. (Id. at 12).
3
Again, rebuttal expert testimony must address the “same subject matter” identified
4
by the initial expert. Fed. R. Civ. P. 26(a)(2)(C)(ii); Lindner, 249 F.R.D. at 636. In other
5
words, “[t]he function of rebuttal testimony is to explain, repel, counteract or disprove
6
evidence of the adverse party.” Armer v. CSAA Gen. Ins. Co., 2020 WL 3078353, at *5
7
(D. Ariz. June 10, 2020) (citing Marmo v. Tyson Fresh Meats, Inc., 457 F.3d 748, 759
8
(8th Cir. 2006)). Deciding whether an opinion is a proper rebuttal opinion in nature is
9
largely a factual determination that is entrusted to the sound discretion of the district
10

(Id. at 2–3). From his review, Dr. Wolfe criticizes Dr. Fowler’s opinion, stating that:
Dr. Fowler’s opinion regarding the dune profile is not founded or based
upon a reasonable degree of scientific certainty. Dr. Fowler’s basis for his
opinion regarding the sand dune is based upon scan data of a different
location and two cones placed by the Officers over 2 years after the subject
incident. By his own admission, Dr. Fowler opines that the subject sand
dune had migrated eastward and that none of the available file material
provided a clear depiction to assist with establishing its size and geometry.
Dr. Fowler also noted that multiple vehicles driving over the dune postcrash created additional difficulties in determining the path of the Honda
and the impact location on the dune.
- 23 -

...

Based on a review of Dr. Fowler’s report, he performed a trajectory or
airborne analysis of the Honda as it traversed a dune (albeit not the subject
dune topography). Dr. Fowler relied entirely on witnesses who did not see
the incident, with the exception of Greg Updike, who caught a split second
of the incident in his rear-view mirror. Dr. Fowler states that using the
commercially available software program Working Model 2D, the speed at
which the Talon left the dune crest was estimated and motion during the
end-over incident was modeled. The Working Model 2D project appears to
be based upon the aforementioned scan data of a nearby dune profile
selected over 2 years after the subject incident. Based upon the fundamental
laws of physics, the topography on which the Honda was traversing would
have a direct effect on the kinematics and trajectory of the vehicle.

(Id. at 8–9). Dr. Wolfe offers the following specific conclusions/ opinions based on his
review:
1) The description of the slope, rise, and run of the subject dune varied
significantly based upon a review of the available deposition testimony.
2) There are no known measurements that were taken of the subject dune,
such as, rise, run, or slope.
3) The deposition testimony clearly establishes that the terrain and
topography of the subject dune has changed from February 7, 2020. This is
also supported by literature regarding the environmental effects on sand
dunes and by common sense.
4) Dr. Fowler’s basis for his opinion regarding the characteristics or
topography of the sand dune is based upon scan data of a location on a
different dune face delineated by two cones placed 2 years after the subject
incident by other recreational riders who happened to be off-duty officers.
5) Dr. Fowler’s basis and foundation for his inputs into the Working Model
2D as it relates to the dune topography is not based upon any direct
measurement of the subject dune.
6) Dr. Fowler’s inputs for his analysis are not (and cannot be) based upon a
reasonable degree of scientific certainty.
(Id. at 11–12).
26
The Court finds that Dr. Wolfe’s testimony is proper rebuttal expert testimony.
27
First, being a Ph.D in Electrical and Computer Engineering and being accredited as a
28
traffic accident reconstructionist, Dr. Wolfe is qualified to testify as an expert on accident
- 24 -
1
reconstruction due to his education, training and experience.
2
Furthermore, he does not simply restate Dr. Fowler’s opinions—he contradicts them
3
based on his review of the record—which is permissible. See Carter v. Johnson &
4
Johnson, 2022 WL 4700575, at *3 (D. Nev. Sept. 29, 2022) (“an expert can criticize
5
another expert’s methodology without affirmatively disproving the matter himself.”)
6
(citation omitted). In fact, “[t]his type of testimony [is] much more informative than
7
merely presenting those issues to [the opposing party’s expert] on cross-examination” as
8
it is “helpful to the trier of fact to hear these criticisms from an expert.” Id. (quoting
9
Aero-Motive Co. v. Becker, 2001 WL 1698998, *4-6 (W.D. Mich. Dec. 6, 2001)). Dr.
10
Fowler was asked to “reconstruct the accident based upon the materials provided, the
11
inspections and analyses described below and, my knowledge and experience in the field
12
of off-road vehicle design, performance, and operation.” (Doc. 92-4 at 2). Dr. Wolfe,
13
through his own report, has attempted to “repel, counteract or disprove” Dr. Fowler’s
14
opinions—which is the “function of rebuttal testimony.” Armer, 2020 WL 3078353, at
15
*5. For example, Dr, Wolfe critiques Dr. Fowler for relying “entirely on witnesses who
16
did not see the incident, with the exception of Greg Updike, who caught a split second of
17
the incident in his rear-view mirror.” (Doc. 92-2 at 11). He also states that Dr. Fowler’s
18
opinions “regarding the dune profile [are] not founded or based upon a reasonable degree
19
of scientific certainty” because his basis for his opinion regarding the sand dune is “based
20
upon scan data of a different location and two cones placed by the Officers over 2 years
21
after the subject incident.” (Id. at 8). Thus, Dr. Wolfe’s attempts to rebut the credibility
22
of Dr. Fowler’s opinions through these opinions and conclusions will be helpful to the
23
trier of fact since he is also an expert. See Carter, 2022 WL 4700575, at *3.
24
Fed. R. Evid. 702.
Furthermore, Dr. Wolfe is not “misstating the law” as he does not opine on any
25
“ultimate issue.”
Fed. R. Evid. 704.
Instead, his testimony attempts to rebut the
26
credibility of Dr. Fowler’s expert opinion. Defendant is correct that “[d]etermining the
27
credibility of witnesses [falls] within the exclusive province of the jury,” Taylor, 2023
28
WL 2652602, *3, but to determine credibility, the opposing party may advance evidence
- 25 -
1
that a witness is not credible. The Federal Rules of Evidence specifically allow this type
2
of testimony: “Any party, including the party that called the witness, may attack the
3
witness’s credibility.” Fed. R. Evid. 607. So, Dr. Wolfe has not misstated the law.
4
Dr. Wolfe’s testimony is also relevant, so, it will aid, rather than confuse, the jury.
5
See Temple, 40 F. Supp. 3d at 1161; Fed. R. Evid. 702(a). Dr. Wolfe’s testimony will
6
necessarily attack the credibility of Dr. Fowler’s and, again, “it is the jurors’
7
responsibility to determine credibility by assessing the witnesses and witness testimony
8
in light of their own experience.” Sine, 493 F.3d 1021, 1034–35 (9th Cir. 2007) (internal
9
citation omitted). Of course, as a rebuttal expert, he cannot testify in Plaintiff’s case-in-
10
chief and cannot testify at all unless and until Dr. Fowler testifies as to the opinions for
11
which has been designated as a rebuttal expert. See Lindner, 249 F.R.D. at 636.
12
In sum, the Court finds that Dr. Wolfe’s opinions are proper rebuttal opinions in
13
nature, which is a determination entrusted to the sound discretion of this Court, Estate of
14
Goldberg, 2019 WL 8227387, *2, and the Court will not exclude him from testifying as
15
such.
16
F.
17
Finally, Defendant seeks to exclude Plaintiff’s damages expert, Jamie Winkler, as
18
his opinions are “wholly inconsistent with Arizona law with respect to the damages
19
recoverable by individual beneficiaries in a wrongful death action.”5 (Doc. 93 at 1).
20
Defendant argues that Mr. Winkler’s opinions will not assist the jury because (1) he has
21
used the wrong legal standard in calculating the losses [Decedent’s] Estate incurred as a
22
result of his death and (2) his methodology is unreliable. (Id. at 7, 8). It also argues that
23
Mr. Winkler is not qualified to testify as an expert because: (1) he is not a certified public
24
accountant; (2) he has never obtained any certifications in the field of finance; and (3)
25
does not have any graduate level education. (Id. at 4–5). Plaintiff argues that Mr.
26
Winkler is a qualified expert and that his testimony is admissible as Decedent’s statutory
Mr. Winkler
27
Defendant states that Decedent’s statutory beneficiaries “have derived and will continue
to derive substantial economic benefits as a result of [Decedent’s] estate planning that
they would not have enjoyed but for his death.” (Doc. 93 at 4).

beneficiaries are entitled to lost future income. (Doc. 106 at 3, 12).
1.
Mr. Winkler’s Opinions
3
Mr. Winkler was engaged to “opine on damages stemming from the alleged
4
wrongful death of [Decedent].” (Doc. 93-6 at 4). Winkler states in his initial expert
5
report that he has “extensive experience in the determination of economic damages,
6
including matters involving lost earnings.” (Id.) Mr. Winkler holds a bachelor’s degree
7
in economics as well as finance and “has experience in cases involving personal injury,
8
breach of contract, patent and trademark infringement, and franchise matters, among
9
other causes of action.” (Id. at 9). He has also “issued expert reports and offered
10
testimony on such matters.” (Id.)
11
In this report, Mr. Winkler approximates Decedent’s lost earnings for his work life
12
expectancy (74 years old) and his life expectancy (84 years old). (Doc. 93-6 at 8).
13
Decedent was 70 years old at the time of his death. (Id. at 4). Decedent was the
14
president of Updike Distribution Logistics (“UDL”) a company he founded and owned
15
25% of. (Id. at 4, 16). Mr. Winkler estimates Decedent’s total damages at $4,550,211
16
for his work life expectancy and $5,377,091. (Id. at 8). This is based on Decedent’s lost
17
salary of approximately $106,000 per year as well as quarterly profit distributions from
18
UDL. (Id. at 5–6). To estimate the value of these quarterly profit distributions, Mr.
19
Winkler projected UDL’s net income through Decedent’s life expectancy and assumed a
20
“conservative” two-percent annual growth rate. (Id. at 6–7). Based on this analysis, Mr.
21
Winkler states that “the total value of [Decedent’s] Future Lost Distributions is
22
$14,285,342” but that he then “discounted this revenue stream back to the date of this
23
report” at a rate of 18.8%. (Id. at 7). Applying this discount rate, Mr. Winkler calculates
24
“the present value of [Decedent’s] Future Lost Distributions [as] $5,454,939.” (Id.) Mr.
25
Winkler also takes into account that Decedent’s 25% stake in UDL was bought out for
26
$3,356,000 and off sets this price by the present value of the buyout price ($1,936,923) to
27
calculate an offset of $1,419,077.
28
“consumption offset” for the expenditures Decedent would have incurred if he were
(Id. at 8).
- 27 -
Finally, Mr. Winkler calculated a
1
alive. (Id.) Mr. Winkler calculated that a rate of 13.5% based on the “Patton-Nelson
2
Personal Consumption Tables,” a “reputable study that considers gender, income, and
3
household size.” (Id.) Mr. Winkler also provides tables and schedules which show, in
4
detail, howe he came to these calculations. (Id.)
5
Mr. Winkler also provided a rebuttal expert report in response to Defendant’s
6
expert: Craig Reinmuth. (Doc. 106-1 at 20). Reinmuth’s report “argues that Valerie
7
[Updike (Decedent’s spouse)] sustained zero damages, despite being deprived of an
8
income stream that would have generated millions over the coming years.” (Id. at 21).
9
Mr. Winkler states that Mr. Reinmuth’s report reduces Winkler’s damages calculation by
10
97% but that this is driven by “unsupported or otherwise flawed adjustments.” (Id.)
11
Winkler admits that Reinmuth’s report identified an error within his calculated life
12
expectancy which added an extra year to Decedent’s life expectancy. (Id.) Mr. Winkler
13
also admits that Reinmuth’s report identified an error in the buyout offset calculation
14
where the “but-for buyout” was not discounted to the date of the actual buyout, but the
15
date of his report which results is a 10% reduction. (Id. at 22). There also seems to be
16
some dispute between Mr. Winkler and Mr. Reinmuth in whether to deduct income taxes
17
from the damages calculation since this is a “legal determination” which “hinges on
18
whether the awarded damages will be taxable.” (Id. at 27). In sum, Mr. Winkler states
19
that he has incorporated the following changes to his report:
20
• Adjusts life expectancy to February 13, 2034
21
• Adjusts measurement date of buyout offset to May 14, 2020
22
• Updates discount rates based on current U.S. Treasury yields
23
• Updates UDL Projection based on actual performance through Q3 2022
• Presents an alternative which accounts for income taxes
24
25
(Id. at 28). Mr. Winkler provides the following summary of his calculations:

(Id.) Mr. Winkler has also provided exhibits showing how he came to these conclusions
based on his calucaltions. (See id. at 32–39).
2.
Mr. Winkler is Qualified to Testify as an Expert
13
First, the Court finds that Mr. Winkler is a qualified expert witness. An expert
14
may be qualified by “knowledge, skill, experience, training, or education.”
15
Fed. R. Evid. 702.
16
finance—which are directly relevant to his opinions. (Doc. 93-6 at 9). Mr. Winkler also
17
has relevant experience evaluating and calculating economic losses, specifically as it
18
pertains to economic losses in various personal injury cases. (Doc. 106-1 at 29–30).
19
While Mr. Winkler’s experience in testifying is sparce, “[p]rior experience need not
20
consist of prior expert witness testimony on the same issue.” In re ConAgra Foods, Inc.,
21
302 F.R.D. 537, 551 (C.D. Cal. 2014) (citation omitted); see also id. (“If witnesses could
22
not testify for the first time as experts, we would have no experts”).
23
“threshold for qualification is low for purposes of admissibility; minimal foundation of
24
knowledge, skill, and experience suffices.” Id. (citation omitted). The Court finds that
25
Mr. Winkler meets this “low” threshold through his knowledge, experience and education
26
as he has relevant education and experience.

Goodrich Tire Co., 919 F. Supp. 1353, 1357 (D. Ariz. 1996), aff'd, 114 F.3d 851 (9th Cir.

qualifications as an expert if only technical knowledge is required. If, however, scientific
2
knowledge is necessary the expertise must be coextensive with the particular scientific
3
discipline.”).
4
3.
Mr. Winkler’s Methodology is Sufficiently Supported
5
Next, Defendant’s argument that Mr. Winkler’s methodology is unreliable does
6
nor persuade the Court to exclude him. Most of Defendant’s arguments, such as Mr.
7
Winkler’s assumption that Decedent would have worked through his natural life, are
8
disagreements with the basis for Mr. Winkler’s opinions. These arguments go to the
9
weight of this evidence, not its admissibility, as these assumptions are based on the facts.
10
Johnson, 2023 WL 8852489, at *4 (“Defendants’ arguments as to the evidentiary support
11
for [the expert]’s opinions go to the weight of his testimony, rather than its
12
admissibility.”); see also United States v. L.E. Cooke Co., 991 F.2d 336, 342 (6th Cir.
13
1993) (“any weaknesses in the factual basis of an expert witness’ opinion . . . bear on the
14
weight of the evidence rather than on its admissibility”).
15
Furthermore, Defendant’s argument that Mr. Winkler failed to use a “company
16
risk factor” is not a basis for exclusion because “[n]ormally, failure to include variables
17
will affect the analysis’ probativeness, not its admissibility.” Hemmings v. Tidyman’s
18
Inc., 285 F.3d 1174 (9th Cir. 2002) (quoting Bazemore v. Friday, 478 U.S. 385, 400
19
(1986)). Instead, a “vigorous cross-examination” allows the jury to “appropriately weigh
20
the alleged defects and reduces the possibility of prejudice.” Id. (citation omitted).
21
Stated differently, Mr. Winkler’s report is not “so incomplete as to be inadmissible as
22
irrelevant.” Id; see also Primiano, 598 F.3d at 564 (“Shaky but admissible evidence is to
23
be attacked by cross examination, contrary evidence, and attention to the burden of proof,
24
not exclusion.”).
25
supported his methodology such that exclusion at this stage would be improper. See
26
Joiner, 522 U.S. at 142.

In sum, the Court, in its discretion, finds that Mr. Winkler has
Mr. Winkler’s Opinions are Consistent with Arizona law
Finally, Defendant’s argument that Mr. Winkler’s damages calculation is
- 30 -
1
inconsistent with Arizona law is unpersuasive.
2
Winkler has “made no attempt to calculate the ‘reasonable value of the economic support
3
and maintenance’ which [Decedent] may have provided to the statutory beneficiaries
4
during his lifetime.” (Doc. 93 at 7). Plaintiff argues that “[i]t is settled Arizona law that
5
a surviving spouse is entitled to recover ‘[t]he income and services that have already been
6
lost as a result of the death, and that are reasonably probable to be lost in the future.’ ”
7
(Doc. 106 at 4 (citing Revised Arizona Jury Instructions (“RAJI”) (Civil) (7th Ed.)).
Defendant specifically argues that
8
In Arizona, “[a]s a general rule, a plaintiff in a tort action is entitled to recover
9
such sums as will reasonably compensate him for all damages sustained by him as the
10
direct, natural and proximate result of such negligence, provided they are established with
11
reasonable certainty.” Nunsuch ex rel. Nunsuch v. United States, 221 F. Supp. 2d 1027,
12
1034 (D. Ariz. 2001 (quoting Continental Life & Accident Co. v. Songer, 124 Ariz. 294,
13
304 (1979)). “Arizona allows unlimited recovery for actual damages, expenses for past
14
and prospective medical care, past and prospective pain and suffering, lost earnings, and
15
diminished earning capacity.” Id. (quoting Wendelken v. Superior Court in and for Pima
16
County, 137 Ariz. 455, 671 P.2d 896 (1983) (emphasis added). However, “[l]oss of
17
earnings is an item of special damage and must be specially pleaded and proved.” Id.
18
(quoting Mandelbaum v. Knutson, 11 Ariz. App. 148, 149, 462 P.2d 841, 842 (1969)). In
19
a wrongful death action, “wrongful death damages are statutorily limited to injuries
20
‘resulting from the death,’ which may include the decedent’s prospective earning
21
capacity.” Walsh v. Advanced Cardiac Specialists Chartered, 229 Ariz. 193, 196, 273
22
P.3d 645, 648 (2012) (internal citations and quotations omitted). Statutory beneficiaries
23
in a wrongful death action “can recover their economic loss resulting from death.” Popal
24
v. Beck, 2022 WL 457363, at *3 (Ariz. Ct. App. Feb. 15, 2022).
25
Here, as Defendant itself notes, A.R.S. § 12-613 permits a damage award to “the
26
surviving parties who may be entitled to recover” which include a “surviving husband or
27
wife, child, parent or guardian, or personal representative” on their behalf. A.R.S. § 12-
28
612(A). Indeed, an “estate is not entitled to economic damages under the wrongful death
- 31 -
1
statute because it can seek such damages only if none of the statutory beneficiaries

survive.” Popal, 2022 WL 457363, at *3. Here, however, Decedent is survived by his
3
statutory beneficiaries and they have brought this action under A.R.S. § 12-612 as
4
“beneficiaries” and specifically seek “surviving statutory wrongful death” damages.
5
(Doc. 1-2 at 13, 21 (“[Plaintiff] is the surviving biological son of [Decedent] and brings
6
this action for himself and for all eligible statutory wrongful death beneficiaries under
7
A.R.S. § 12-612(A), including Valerie Updike, the decedent’s surviving wife, and the
8
decedent's surviving sons, James Updike, Jr., Greg Updike and Jeffrey Updike.”)). So,
9
Mr. Winkler’s calculations are not “inconsistent with Arizona law” as A.R.S. § 12-612
10
specifically allows for the recovery of loss of future earnings in a wrongful death action.

See Walsh, 273 P.3d at 648; Popal, 2022 WL 457363, at *3.

In sum, the Court will not exclude Mr. Winkler here.
