Case No. CIV-13-178-D
ORDER
Before the Court is Defendant Robert Bosch Tool Corporation’s Motion to
Exclude the Expert Testimony of Plaintiff’s Expert, Dr. Robert Anderson [Doc. No.
63]. Plaintiffs have filed their response in opposition [Doc. No. 69] and Defendant
has replied [Doc. No. 74]. The matter is fully briefed and at issue.
BACKGROUND
Plaintiff, Hanna AlNahhas (“Plaintiff”), was injured while operating a random
orbit sander manufactured by Defendant. Under tort theories of strict products
liability and negligence, Plaintiffs sued Defendant alleging the sander was
defectively designed and had inadequate warnings.
1
1
In support of the claims,
The Court previously granted Defendant’s Motion for Summary Judgment, finding
that the sander’s warnings were adequate and Plaintiff had failed to establish either
the existence of a defect or that the sander was unreasonably dangerous. On appeal,
the Tenth Circuit concluded genuine disputes of material fact existed on both claims
Plaintiffs retained the services of Dr. Robert Anderson. Dr. Anderson is president of
RNA Consulting, Inc., where he specializes in forensic engineering. His areas of
expertise include metallurgical failure analysis, corrosion, thermodynamics,
engineering design failure, electrical fires, ballistics, and accident analysis. Dr.
Anderson described his occupation thusly:
I do failure analysis, and a component of that is to look at what would
have prevented that failure, whether it was changing some
compositional area, reinforcing area or warnings, and so just about
every issue I address, there [is] some concept in there about what could
have stopped the injury from occurring.
Depo. of Robert Anderson at 36:14-19.
Dr. Anderson received his Ph.D in Metallurgy from Stanford University and
his bachelor and master of science degrees in Chemical Engineering from the
University of California, Berkley. At the time of his report, he was an emeritus
professor at California State University at San Jose. Among other licenses, he is a
registered metallurgical engineer and is certified in the specialty of forensic
engineering. He takes classes every year on product failure and has authored several
publications regarding forensic engineering.
At Plaintiffs’ request, Dr. Anderson examined the sanding disc at issue with
a stereo microscope and scanning electron microscope. He did not test any other pad,
and remanded the case for further proceedings. See AlNahhas v. Robert Bosch Tool
Corp., 706 F. App’x 920 (10th Cir. 2017) (unpublished).
2
but did examine an exemplar pad similar to the one used by Plaintiff. Dr. Anderson
testified that in addition to examining the sander, he reviewed Plaintiff’s discovery
requests and Defendant’s answers to Plaintiff’s Requests for Admission. He also
reviewed drawings produced by Defendant during discovery, as well as literature on
the sander and the operating manual.
After examining the pad, he issued a written report (the Anderson Report)
detailing his findings and conclusions. The report consisted of two general opinions:
(1) Defendant did not specify or warn as to the end of life behavior of the sanding
disc and should not have sold the disc without such warning, and (2) there was a
design defect in the molding process, which made the disc unreasonably dangerous
and caused it to lose its “strength” over time. Specifically, Dr. Anderson’s report
stated:
In my opinion, the presence of voids and the mixture of brittle and
plastic regions made the sanding disc too weak for the intended use.
Further, there is no warning that the sanding disc can fracture after
extended use.
The manufacturer’s molding process was the cause of the failure, and
this made the disc unreasonably dangerous. [Defendant] did a number
of tests on the orbital sander, but did not specify or warn as to end-oflife behavior of the disc. Without providing documentation or warnings
on how the disc might fail, [Defendant] should not have sold these
discs.
It is reasonable to expect that without initially putting on safety glasses,
a user might test the functioning of the orbital sander before starting
work. Therefore, knowledge of the stability of the disc during its
lifetime is critical.
3
The manufacturing defects and the lack of warnings with regard to the
end-of-life behavior resulted in a dangerous condition that caused the
injury to [Plaintiff].
Anderson Report at 2.
At his deposition, Dr. Anderson was asked to elaborate on his opinion
regarding the disc’s design, wherein he testified “[t]he fact that [the sanding disc] is
actually composite made of brittle hard material in conjunction with soft foamy
material and the behavior that occurs when you have two mismatched materials …
that would give a better explanation, a more complete explanation of the failure, the
cause.” Anderson Depo. at 9:10-17. He opined that the tool’s warning should have
indicated that the disc may fail, that such failure would be in a “dynamic manner,”
that the user may be struck by some part of the disc, and that eye protection should
be worn at all times.
Defendant contends Dr. Anderson should be excluded as a witness because
(1) he is unqualified to give the opinions at issue, (2) his opinions are not reliable or
relevant, and (3) he did not rely on any articulable scientific methods or principles
in reaching either opinion regarding design or warning defect. In response, Plaintiff
contends that Dr. Anderson is well qualified to testify on the subjects in his report,
his opinions are relevant, and the opinions will assist the trier of fact.

STANDARD OF DECISION
Courts have broad discretion in determining the admissibility of expert
testimony. Taylor v. Cooper Tire & Rubber Co., 130 F.3d 1395, 1397 (10th Cir.
1997); see also Abraham v. WPX Production Prods., LLC, 184 F. Supp. 3d 1150,
1187 (D.N.M. 2016) (“Courts should, under the Federal Rules of Evidence, liberally
admit expert testimony….”) (citing United States v. Gomez, 67 F.3d 1515, 1526
(10th Cir. 1995)). A district court also has broad discretion to decide “how to assess
an expert’s reliability, including what procedures to utilize in making that
assessment, as well as in making the ultimate determination of reliability.” Etherton
v. Owners Ins. Co., 829 F.3d 1209, 1216 (10th Cir. 2016) (quoting Goebel v. Denver
& Rio Grande W. R.R. Co., 346 F.3d 987, 990 (10th Cir. 2003)). “As the Supreme
Court said in [Kumho Tire Co. v. Carmichael, 526 U.S. 137 (1999)], ‘[t]he trial judge
must have considerable leeway in deciding in a particular case how to go about
determining whether particular expert testimony is reliable.’” Id. (quoting Kumho
Tire, 526 U.S. at 152).
The admissibility of expert testimony is governed by Federal Rule of
Evidence 702 and the Supreme Court’s opinions in Daubert v. Merrell Dow
Pharmaceuticals, Inc., 509 U.S. 579 (1993) and Kumho Tire, supra. See James River
Ins. Co. v. Rapid Funding, LLC, 658 F.3d 1207, 1215 n. 1 (10th Cir. 2011) (“If expert
testimony is not reliable under Daubert/Kumho, it is not admissible under Rule
5
702.”). Rule 702 imposes upon the trial judge an important “gate-keeping” function
with regard to the admissibility of expert opinions. It provides:
A witness who is qualified as an expert by knowledge, skill, experience,
training, or education may testify in the form of an opinion or otherwise
if:
(a) the expert’s scientific, technical, or other specialized knowledge
will help the trier of fact to understand the evidence or to
determine a fact in issue;
(b) the testimony is based on sufficient facts or data;
(c) the testimony is the product of reliable principles and methods;
and
(d) the expert has reliably applied the principles and methods to the
facts of the case.
Fed. R. Evid. 702. In considering whether a putative expert’s opinion is admissible,
the Court performs a two-step analysis. First, the court determines whether the expert
is qualified by knowledge, skill, experience, training or education to render the
opinion that the would-be expert offers. Second, if the expert is so qualified, the
Court must decide whether the expert’s opinion is reliable under the principles set
forth in Daubert and Kumho Tire and would assist the fact finder. 103 Investors I,
L.P. v. Square D Co., 470 F.3d 985, 990 (10th Cir. 2006); Ralston v. Smith & Nephew
Richards, Inc., 275 F.3d 965, 969 (10th Cir. 2001).2
2
In assessing the reliability of scientific or other specialized evidence, the Daubert
Court enumerated four “non-exclusive” factors: (1) whether the expert’s technique
or theory can be and has been tested; (2) whether the theory has been subject to peer
review and publication; (3) whether the method has a high known or potential rate
of error of the technique or theory when applied and if there are standards and
controls controlling the method’s operation; and (4) whether the method is generally
accepted in a relevant scientific community. Kumho Tire, 526 U.S. at 149-50.
6
“The Daubert factors are ‘meant to be helpful, not definitive,’ and not all of
the factors will be pertinent in every case.” United States v. Baines, 573 F.3d 979,
992 (10th Cir. 2009) (quoting Kumho Tire, 526 U.S. at 150-51). Thus, in
nonscientific cases, the Daubert factors “may or may not be pertinent in assessing
reliability, depending on the nature of the issue, the expert’s particular expertise, and
the subject of his testimony.” Kumho Tire, 526 U.S. at 150. The inquiry is always,
and of necessity, highly fact-specific, and no one factor, even when applicable, is
outcome-determinative. Accordingly, “the law grants a district court the same broad
latitude when it decides how to determine reliability as it enjoys in respect to its
ultimate reliability determination.” Id. at 142 (citing General Electric Co. v. Joiner,
522 U.S. 136, 143 (1997)).
DISCUSSION
Based on the evidence in the record, the Court finds a formal hearing on
Defendant’s motion is unnecessary. “Tenth Circuit cases have interpreted Kumho
Tire’s directive that courts must have leeway in applying the Daubert framework to
mean that although Daubert hearings are the most common way to fulfill the
gatekeeper function, ‘such a process is not specifically mandated.’” United States v.
Nacchio, 555 F.3d 1234, 1253-54 (10th Cir. 2009) (citations omitted); United States
v. Charley, 189 F.3d 1251, 1266 (10th Cir. 1999) (“The trial judge is granted great
latitude in deciding which factors to use in evaluating the reliability of expert
7
testimony, and in deciding whether to hold a formal hearing.”) (citation omitted).
Accordingly, the Court will rule on Defendant’s motion based on the parties’
submissions. See also Ho v. Michelin N. Am., Inc., 520 F. App’x 658, 664 (10th Cir.
2013) (unpublished) (court properly exercised its discretion in issuing Daubert
ruling without formal hearing due to number of expert reports, deposition transcripts,
and other evidence that accompanied the parties’ arguments).
I.
Qualification
Pursuant to the foregoing standard, the Court finds that although Dr. Anderson
is qualified to testify about an alleged design defect in the sanding disc at issue, this
expertise does not qualify him as an expert as to warnings. It is undisputed that Dr.
Anderson has never designed a warning for a product, power tool, or a sanding pad.
See Anderson Depo. at 34:5-25 (Q: Have you ever been involved in developing a
warning for a product? A: No, I don’t believe I have ... Q: Do you have any
experience or training in developing a warning for a power tool? A: No. Q: Do you
have any experience or training in developing a warning for a sanding pad? A: No.
… Q: Do you have any experience or training in developing a warning for a foam
product? A: Other than my reading, no.). He has had no experience or training in
developing a warning for a power tool or sanding pad. Id. at 34:20-25. Nor has he
conducted research on, or published any work regarding product warnings. Id. at
43:16-25—44:1-9.
8
Although Dr. Anderson testified that he had taken classes on developing
warnings and read a “number of books” on the subject matter, the fact he may have
some marginal familiarity with developing product warnings is a far cry from
classifying him as an “expert” on the issue. Under Daubert and Rule 702, “the
touchstone of the admissibility of expert testimony is its helpfulness to the trier of
fact.” U.S. Aviation Underwriters, Inc. v. Pilatus Business Aircraft, Ltd., 582 F.3d
1131, 1150 (10th Cir. 2009) (citation omitted). Stated another way, “[t]he issue with
regard to expert testimony is not the qualifications of a witness in the abstract, but
whether those qualifications provide a foundation for a witness to answer a specific
question.” Graves v. Mazda Motor Corp., 675 F. Supp. 2d 1082, 1092-93 (W.D.
Okla. 2009) (quoting Berry v. City of Detroit, 25 F.3d 1342, 1351 (6th Cir.1994),
cert. denied, 513 U.S. 1111 (1995)). “Thus, on the issue of expert qualifications,
Ralston and like cases establish that the qualifications of the proposed expert are to
be assessed only after the specific matters he proposes to address have been
identified. The controlling Tenth Circuit cases, exemplified by Ralston, establish
that the expert’s qualifications must be both (i) adequate in a general, qualitative
sense … and (ii) specific to the matters he proposes to address as an expert.” See id.
at 1093 (citations omitted).
Dr. Anderson’s stated expertise is in forensic/metallurgical engineering. In the
Court’s view, the adequacy of the warning regarding the sanding disc is not within
9
the reasonable confines of Dr. Anderson’s subject area of expertise and his proposed
testimony should be curtailed in this regard. Compare American Auto. Ins. Co. v.
Omega Flex, Inc., No. 4:11CV00305, 2013 WL 2628658, at *6 (E.D. Mo. June 11,
2013) (precluding opinion testimony on adequacy of warnings in product liability
case where expert’s stated specialty was metallurgy and physics).
Moreover, the ultimate issue of whether the sander’s warning labels were
adequate is a matter within a jury’s common sense and everyday knowledge, which
would not require or benefit from expert assistance. See Robertson v. Norton Co.,
148 F.3d 905, 908 (8th Cir. 1998) (questions surrounding adequacy of warning on
sander/grinder wheel was ultimate issue of fact for the jury); Roman v. Sprint Nextel
Corp., No. 12-CV-276, 2014 WL 5870743, at *2 (S.D.N.Y. Nov. 13, 2014)
(“Because the jury steps into the shoes of the average user, it does not need expert
testimony to evaluate a warning; the ultimate issue of the adequacy of a warning is
a question of fact for the jury based on the totality of the circumstances.”) (citing
Billar v. Minn. Mining & Mfg. Co., 623 F.2d 240, 247 (2d Cir. 1980)). The jury will
have an opportunity to view the warnings themselves, and the Court is convinced
that the jury is competent to decide whether the warning labels were adequate under
the circumstances. Although experts may generally aid a jury by rendering opinions
on ultimate issues, see Fed. R. Evid. 704, courts must guard against invading the
10
province of the jury on a question which the jury was entirely capable of answering
without the benefit of expert testimony.
However, the Court finds Dr. Anderson is qualified to render an opinion
regarding the sanding pad’s design. On this issue, Defendant attacks Dr. Anderson’s
qualifications on the grounds he has neither designed a power tool nor has experience
designing sanding pads or foam products and did not consult other manufacturers’
designs for sanding pads. However, a court enjoys broad discretion in determining
whether an expert is qualified and “[a] court abuses its discretion if it refuses to
qualify a witness as an expert solely because the expert does not have the degree or
specialization that the court considers to be most appropriate.” United States v.
McCluskey, 954 F. Supp. 2d 1224, 1241 (D.N.M. 2013) (citing Pages-Ramirez v.
Ramirez-Gonzalez, 605 F.3d 109, 114 (1st Cir. 2010)). The text of Rule 702
expressly contemplates that an expert may be qualified on the basis of “knowledge,
skill, experience, training, or education ….” Fed. R. Evid. 702. Any one of these
bases is sufficient. As noted above, Dr. Anderson has significant expertise in
forensic engineering and metallurgical design, including but not limited to, design
failure and accident analysis. The accumulation of this training and experience, in
the Court’s view, renders him capable of testifying on the product’s design.
Defendant’s arguments against Dr. Anderson on this issue go to the weight of
his testimony, not its admissibility. “As long as an expert stays ‘within the
11
reasonable confines of his subject area,’ [Tenth Circuit] case law establishes ‘a lack
of specialization does not affect the admissibility of [the expert] opinion, but only
its weight.’ ” Ralston v. Smith & Nephew Richards, Inc., 275 F.3d 965, 970 (10th
Cir. 2001) (quoting Compton v. Subaru of Am., Inc., 82 F.3d 1513, 1519-20 (10th
Cir. 1996)). “Daubert did not work a ‘seachange over federal evidence law,’ and
‘the trial court’s role as gatekeeper is not intended to serve as a replacement for the
adversary system.’” Fed. R. Evid. 702, advisory committee’s note to 2000
amendment. Only when “an expert opinion is so fundamentally unsupported that it
can offer no assistance to the jury” must such testimony be excluded. Hose v.
Chicago Northwestern Transp. Co., 70 F.3d 968, 974 (8th Cir. 1995). Thus, rejection
of expert testimony is the exception rather than the rule, and vigorous crossexamination, presentation of contrary evidence, and careful instruction on the burden
of proof are the traditional and appropriate means of attacking shaky but admissible
evidence. Daubert, 509 U.S. at 595. Accordingly, Defendant’s motion on this issue
is denied.
II.
Methodology and Reliability3
In order to establish an expert’s testimony as reliable, the proponent need not
prove the expert is indisputably correct; rather, the party must show the method
3
Having found Dr. Anderson may not testify as to the adequacy of warnings,
Defendant’s argument regarding the reliability of his opinion on that issue is
considered moot.
12
employed by the expert in reaching his conclusion is sound and the opinion is based
on facts which sufficiently satisfy Rule 702’s reliability requirements. Reed v. Smith
& Nephew, Inc., 527 F. Supp. 2d 1336, 1346 (W.D. Okla. 2007). In other words, if
there are “good grounds” for the expert’s conclusion, it should be admitted. Daubert,
509 U.S. at 590; Mitchell v. Gencorp Inc., 165 F.3d 778, 781 (10th Cir. 1999);
Bonner v. ISP Technologies, Inc., 259 F.3d 924, 929 (8th Cir. 2001) (“[E]ven if the
judge believes there are better grounds for some alternative conclusion, and that
there are some flaws in the [expert’s] methods, if there are good grounds for the
expert’s conclusion, it should be admitted.”).
Defendant contends Dr. Anderson’s opinion about the sander’s alleged design
defects4 should be excluded as unreliable because he: (1) was unfamiliar with the
sander’s design, (2) did not have information on the design process, (3) had no
information as to how Plaintiff used the sander, (4) did not take photos of multiple
discs, (5) collected no supporting data, and (6) conducted no tests on exemplar pads.
Upon review, the Court finds Defendant’s criticisms of Dr. Anderson’s methodology
are more appropriately directed at the weight of his testimony as opposed to its
admissibility. As noted, the Court enjoys broad discretion in deciding how to assess
an expert’s reliability, including what procedures to utilize in making that

whether there was a manufacturing defect.
13
assessment, as well as in making the ultimate determination of reliability. Here, the
Court is unable to conclude that Dr. Anderson’s methodology is so lacking in
fundamental principles of ballistic engineering as to render it unreliable and
irrelevant. Although there are arguably flaws in Dr. Anderson’s method, sufficient
grounds exist for his conclusion and it should be admitted.
In this regard, courts have cautioned against applying the reliability
requirement too strictly, explaining that “the reliability requirement must not be used
as a tool by which the court excludes all questionably reliable evidence.” Voilas v.
General Motors Co., 73 F. Supp. 2d 452, 460 (D.N.J. 1999) (quoting In re Paoli
R.R. Yard PCB Litig., 35 F.3d 717, 742 (3d Cir. 1994)). Rather, “[i]n the final
analysis, [t]he touchstone of Rule 702 ... is the helpfulness of the expert testimony,
i.e., whether it will assist the trier of fact to understand the evidence or to determine
a fact in issue.” Id. (citations and internal quotation marks omitted). Thus, “the
perceived flaws in an expert’s testimony often should be treated as matters properly
to be tested in the crucible of the adversarial system, not as the basis for truncating
that process.” Id. at 461-62 (citations and internal quotation marks omitted).
Defendant has every right to explore such perceived weaknesses by means of crossexamination and presentation of contrary evidence. Moreover, the Court will instruct
the jury on the weight afforded expert testimony and the applicable burden of proof.

CONCLUSION
Defendant Robert Bosch Tool Corporation’s Motion to Exclude the Expert
Testimony of Plaintiff’s Expert, Dr. Robert Anderson [Doc. No. 63] is GRANTED
IN PART and DENIED IN PART as set forth herein. Based on the opinions
expressed in this Order, Defendant’s Motion to Strike Dr. Anderson’s Affidavit
[Doc. No. 64] is moot.
IT IS SO ORDERED this 18th day of May 2018.
