I. LEGAL STANDARD
The decision whether to exclude expert testimony is committed to a district court’s
discretion—subject, of course, to the Federal Rules of Evidence, including Rule 702.
Johnson v. Mead Johnson & Co., LLC, 754 F.3d 557, 561 (2014). Rule 702 states that:
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 the
proponent demonstrates to the court that it is more likely than not that:
(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's opinion reflects a reliable application of the principles and
methods to the facts of the case.
The Eighth Circuit has “boiled down” these requirements into a three-part test:
First, evidence based on scientific, technical, or other specialized
knowledge must be useful to the finder of fact in deciding the ultimate issue
of fact. This is the basic rule of relevancy. Second, the proposed witness
must be qualified to assist the finder of fact. Third, the proposed evidence
must be reliable or trustworthy in an evidentiary sense, so that, if the finder
of fact accepts it as true, it provides the assistance the finder of fact requires.
Johnson, 754 F.3d at 561 (quoting Polski v. Quigley Corp., 538 F.3d 836, 839 (8th Cir.
2008)). The proponent of expert testimony bears the burden of showing by a
preponderance of the evidence that these requirements are satisfied. See Marmo v.
Tyson Fresh Meats, Inc., 457 F.3d 748, 757–58 (8th Cir. 2006).
A district court possesses broad discretion in making its reliability determination.
Kumho Tire Co. v. Carmichael, 526 U.S. 137, 142 (1999). When assessing the validity of
expert opinions, the trial court may consider one or more of the following non-exclusive
factors: (1) whether the theory or methodology can be tested; (2) whether the theory or
2
methodology has been subjected to peer review and publication; (3) the known or
potential rate of error; and (4) whether the theory has been generally accepted in the
relevant scientific community. Daubert v. Merrell Dow Pharms., Inc., 509 U.S. 579, 593–
94 (1993). “An expert may base an opinion on facts or data in the case that the expert
has been made aware of or personally observed.” Fed. R. Evid. 702. However, “[e]xpert
testimony that is speculative is not competent proof and contributes nothing to a legally
sufficient evidentiary basis.” J.B. Hunt Transp., Inc. v. Gen. Motors Corp., 243 F.3d 441,
444 (8th Cir. 2001) (internal citations omitted).
“A witness can be qualified as an expert by knowledge, skill, experience, training
or education . . . .” Wheeling Pittsburgh Steel Corp. v. Beelman River Terminals, Inc., 254
F.3d 706, 715 (8th Cir. 2001) (internal quotations omitted). And “[t]he relative skill or
knowledge of an expert goes to the weight of that witness’s testimony, not its
admissibility.” Loudermill v. Dow Chem. Co., 863 F.2d 566, 569 (8th Cir. 1988). “[I]t is the
responsibility of the trial judge to determine whether a particular expert has sufficient
specialized knowledge to assist jurors in deciding the specific issues in [a] case.”
Wheeling Pittsburg Steel Corp., 254 F.3d at 715.
To prove useful to a jury, an expert’s opinion should rely on their specialized
knowledge; “[w]here the subject matter is within the knowledge or experience of lay
people, expert testimony is superfluous.” Ellis v. Miller Oil Purchasing Co., 738 F.2d 269,
270 (8th Cir. 1984). Further, an expert should not make unsupported assertions that go
beyond their area of expertise. See Anderson v. Raymond Corp., 340 F.3d 520, 523 (8th
Cir. 2003) (finding the district court did not abuse its discretion where it prohibited an
3
expert from testifying on matters admittedly beyond his expertise). To that end, an expert
should not opine on legal conclusions, as they will not assist the jury either. Peterson v.
City of Plymouth, 60 F.3d 469, 475 (8th Cir.1995) (“The legal conclusions were for the
court to make. It was an abuse of discretion to allow the testimony.”).
II. DISCUSSION
A. Dr. Randy V. Bradley (Doc. 246)
Walmart has designated Dr. Randy V. Bradley as an expert witness on supply
chains. London Luxury seeks to exclude his testimony because it is speculative, “divorced
from any of the facts of this case,” and “of no use to the jury.” (Doc. 297, p. 5). London
Luxury criticizes Dr. Bradley because he supposedly “did no work to investigate the facts”
and instead discussed in his expert report only general principles and practices used in
supply chain management. Id. Finally, London Luxury critiques Dr. Bradley’s expert report
for containing impermissible legal conclusions.
Despite these critiques about the substance of Dr. Bradley’s opinions, London
Luxury at least agrees that he is a qualified expert in the field of supply chain
management. Dr. Bradley is Associate Professor of Supply Chain Management at the
University of Tennessee. He has published a number of articles in peer-reviewed
publications on various topics in the field of supply chain management. Therefore, the
Court finds him qualified to offer expert testimony on global supply chains and strategic
sourcing, supply chain management, and risk management.
Next, the Court turns to the question of whether Dr. Bradley’s opinions are reliable
and trustworthy in the evidentiary sense and likely to assist the jury in deciding the
4
ultimate issues of fact. He explains in his expert report the effect that supply-chain
disruptions tend to have on the global economy and the importance of transparency in all
aspects of the supply chain. As for the particular challenges supply chains faced during
the COVID-19 pandemic, Dr. Bradley opines that “there were tremors prior to and
unrelated to COVID-19 that could have given organizations reason to fortify ‘weak links’
in their supply chains and supply chain strategies” and mitigate the risk of supply chain
failure. (Doc. 272-1, p. 19). He also opines that high ethical standards are required of
businesses working in each link in the supply chain, since unethical behaviors—like
bribery and lying—negatively impact supply chain efficiency and inhibit “a truly
collaborative relationship between buyers and suppliers.” Id. at p. 20. In the Court’s view,
these opinions are relevant to fact issues that the jury must address in this case.
Therefore, Dr. Bradley’s testimony on these topics is likely to assist the jury.
London Luxury’s objections to Dr. Bradley’s testimony are focused on the last five
pages of his report. See id. at pp. 23–27. He starts off by acknowledging four main factual
disputes the jury must resolve: whether London Luxury failed to deliver goods on time,
whether London Luxury sourced gloves improperly and/or misrepresented its factory
sources, whether London Luxury failed to deliver gloves of adequate quality, and whether
London Luxury bribed a Walmart employee in connection with the glove transaction. Dr.
Bradley does not attempt to resolve any of these factual disputes—which causes London
Luxury to label his report as unhelpful. However, Dr. Bradley does opine as to the negative
effects that would have been likely if London Luxury had done any of these four things.
For example, Dr. Bradley explains in his report how a supplier’s failure to deliver goods
5
by an expected deadline impacts the buyer’s operating costs, potential sales, and
relationships with existing customers. See id. at p. 23. In another section of the report, he
explains how a supplier’s failure to disclose its factory sources prohibits the buyer from
verifying whether those sources “are consistent with the buyer’s established standards
for socially responsible practices.” Id. at p. 25. And if the sources violate the buyer’s
standards, news of this could negatively impact the buyer’s image and jeopardize its
ability to fulfill promises to its customers about responsibly sourcing goods. Id. at p. 24.
The Court finds that these opinions of Dr. Bradley’s are not, as London Luxury
contends, unduly speculative and unreliable. They are based on his expertise regarding
supply chains and the suppliers and buyers who navigate within them. His opinions—
which the Court finds are the product of reliable principles and methods that are reliably
applied to the facts of this case—will likely assist the jury in evaluating whether any breach
or partial breach by London Luxury was material and substantially impaired the contract
as a whole, and he offers a fair counter-opinion to London Luxury’s experts on these
matters. Finally, if Dr. Bradley’s predicate assumptions about the facts of this case are
wrong, London Luxury is free to cross-examine him and test the bases for his opinions.
See Bonner v. ISP Tech., Inc., 259 F.3d 924, 929–30 (8th Cir. 2001) (“As a general rule,
the factual basis of an expert opinion goes to the credibility of the testimony, not the
admissibility, and it is up to the opposing party to examine the factual basis for the opinion
in cross-examination. Only if the expert's opinion is so fundamentally unsupported that it
can offer no assistance to the jury must such testimony be excluded.”).
6
To the extent Dr. Bradley’s rebuttal report could be interpreted as offering legal
opinions, see, e.g., Doc. 274-1, p. 5 (“[T]hose factors do not absolve parties from agreed
upon contractual obligations.”), he is cautioned that such testimony will not be
countenanced by the Court during trial. Dr. Bradley may generally opine that suppliers
and buyers in a supply chain should adhere to their contractual responsibilities, and he
may offer specific opinions about how the parties’ actions here likely affected the players
in the supply chain. But he may not opine on the ultimate legal question, i.e., whether
either party’s particular acts breached the contract. Subject to that admonishment,
London Luxury’s Motion to Exclude the Testimony of Dr. Bradley is DENIED.
B. Dr. Willy C. Shih (Doc. 237)
London Luxury has designated Dr. Willy C. Shih as an expert witness on supply
chains. His expert report is lengthy and detailed, spanning just under 100 pages in length
(not including appendices), and citing to numerous documents in the record. Walmart
does not dispute Dr. Shih’s academic and professional credentials, and the Court finds
him qualified to offer expert testimony on the functioning of supply chains involving
complex or technical products, the impact of manufacturing problems (generally and with
respect to PPE) on supply chains, and the impact of the COVID-19 pandemic on supply
chains, the prices of medical devices, and the demand for PPE.
Walmart criticizes Dr. Shih’s expert report as relying on a selective set of
documents to support a predetermined conclusion. Having reviewed the report in detail,
the Court disagrees with Walmart’s assessment and finds that, for the most part, Dr. Shih
has reviewed and cited hundreds of documents produced by both parties in the course of
7
discovery for the purpose of painting a fair picture of the parties’ business relationship
throughout the course of the pandemic. His opinions are likely to assist the jury in
understanding the context of Walmart’s glove orders and the market forces and structural
and governmental stresses placed on the supply chain at various points in time during
the pandemic. Though Walmart claims Dr. Shih’s testimony about the market price and
demand for gloves changing through the course of the pandemic is not necessary for the
jury to hear, the Court disagrees.
On the other hand, the Court agrees with Walmart that certain portions of Dr. Shih’s
expert report are speculative and improper. In particular, he offers some “ultimate”
opinions as to whether each party did or did not breach the contract, which is for the jury
to decide. For example, he speculates about whether Walmart had just cause to cancel
the contract, whether London Luxury had a good excuse for its delivery delays, whether
delays were out of London Luxury’s control and “not its fault,” and whether Walmart should
have excused London Luxury’s delivery and product-quality failures. See, e.g., Doc. 2391, ¶ 126 (speculating that London Luxury’s “ability to immediately supply gloves was
impeded by issues that arose outside of its control)”; id. at ¶ 166 (opining that London
Luxury’s delays “were entirely outside of its control”); id. at ¶ 171 (opining as to the
ultimate issue that Walmart “walked away from its firm commitments”).
At times, Dr. Shih also improperly enters the corporate mind of Walmart and
speculates about its true motivations for cancelling the contract. He will not be allowed to
enter that headspace at trial. Dr. Shih’s expertise in supply chains clearly qualifies him
to testify as to the market-level context to this litigation—including testimony on the key
8
concepts in supply chains and Covid-19’s impact on the nitrile glove supply chain that he
details in his report. He may also opine as to how supply chain experts would expect a
sophisticated buyer (like Walmart) or seller to act against that contextual background.
However, Dr. Shih may not speculate as to why Walmart did, in fact, act with respect to
the contract at issue in this case. The following passage from Dr. Shih’s report illustrates
this distinction:
A sophisticated purchaser like Walmart would have known its suppliers
would need to rely on certain contractual assurances to assume risk and
that in this case the supply chain was gearing up to satisfy the full
production schedule Walmart had committed to. As I discuss in Section
IV and show in this section, this is because although long-term
agreements can be mutually beneficial, they also carry important
commercial risks for all parties.
Id. at ¶ 106. The problem with that passage is the word, “would.” Dr. Shih may testify that
“Walmart should have known” or that “a sophisticated market actor in the field of supply
chain management would assume that Walmart knew,” and so on. But the current
composition of Paragraph 106 toes the line between Dr. Shih’s expertise and conjecture
into what may be the central issue for the jury to decide: “Did Walmart, in fact, act as an
expert in supply chain management would expect them to as a sophisticated actor in the
contract at bar.” Other passages toe the same line. Compare, e.g., id. at ¶ 141 (footnote
omitted) (“While the disruptions from COVID-19 were unprecedented, Walmart, as one of
the leading global retail firms and top U.S. importer, should have been aware of the
susceptibility of this supplier relationship to the broader global trade disruptions.’) with id.
at ¶ 153 (“[I]t is clear that, by the Fall of 2021, the market situation had evolved from a
dynamic of shortages to greater supply, As I detail in the next section, Walmart was well
9
aware of these changing market dynamics.”). Bearing this distinction in mind, Dr. Shih
must not enter the mind of Walmart in his testimony to the jury—under Anderson he must
testify from his own perspective as an expert. 340 F.3d at 523.
Lastly, some paragraphs in Dr. Shih’s report contain interpretations of the parties’
contract, including his view of the parties’ legal obligations and his assessment of who
was at fault. These are completely improper legal opinions and are not to be presented
to the jury. See, e.g., Doc. 239-1, ¶ 96 (“The Agreement was consistent with the initial
discussions between the two parties for a full upfront commitment from Walmart for the
entirety of the nitrile glove order.”); id. at ¶ 104 (offering a legal opinion for the jury as to
what the February and April Commitment Letters provided and required of each party).
Accordingly, Walmart’s Motion to Exclude the Testimony of Dr. Shih is GRANTED
IN PART AND DENIED IN PART, as set forth above.
C. Mr. Sheshank Kamalapuram (Doc. 260)
Walmart has designated Mr. Sheshank Kamalapuram as an expert witness on
nitrile gloves and the nitrile glove industry. London Luxury seeks to exclude his testimony
as confusing and unhelpful to the jury. In London Luxury’s view, Mr. Kamalapuram applied
no scientific methods in forming his opinions, ignored relevant evidence, and is neither
qualified to speak on glove quality nor quality systems for manufacturing gloves, given
his background as a buyer and seller of gloves.
The Court has reviewed Mr. Kamalapuram’s qualifications and finds he is
competent to offer expert testimony regarding the nitrile glove industry, including during
the COVID-19 pandemic, and to evaluate laboratory testing results of nitrile gloves. He is
10
also qualified to testify about the sourcing, shipment, and distribution of PPE products
before, during, and after the pandemic; the manufacturing process of nitrile gloves; the
function and properties of nitrile gloves; the manufacturing capabilities of facilities that
produce nitrile gloves; and the pricing, production, and quality issues that impacted the
PPE industry before, during, and after the pandemic.
London Luxury first objects that Mr. Kamalapuram “regurgitates the test results”
without analyzing them in a helpful way. (Doc. 263, p. 11). The Court disagrees. His
analysis of the test results is likely to assist the jury.
Second, London Luxury objects to Mr. Kamalapuram’s evaluation of MNA glove
testing, as London Luxury believes MNA did not produce a statistically significant number
of gloves for Walmart, so any failing test results for MNA gloves are irrelevant. Again, the
Court disagrees. Test results for MNA Gloves are a hotly disputed fact issue in this case
and therefore relevant.
Third, London Luxury claims that Mr. Kamalapuram’s opinion reveals that he
actually disagrees with Walmart’s reliance on “one set” of failing test results to draw
conclusions about the quality of a manufacturer’s product. Id. at p. 13. If London Luxury
wishes to make this point to the jury, it may do so on cross-examination; forbidding Mr.
Kamalapuram from testifying about the “one set” of failing gloves would be inappropriate,
as this testimony is relevant to the issues before the jury.
Fourth, London Luxury attacks as conclusory and unsupported Mr. Kamalapuram’s
opinion that retesting of failing products should include every performance metric, not
simply the failing one. Upon review of Mr. Kamalapuram’s expert report and rebuttal
11
report, the Court finds that his opinions on these matters are not conclusory. For example,
he explains in his rebuttal report that several test reports focused on retesting in only two
categories, though the original third-party testing indicated failures in multiple other
categories. He concludes: “This shows the importance of conducting all ASTM required
testing as opposed to picking specific criteria to test.” (Doc. 262-2, p. 9). If London Luxury
disagrees with Mr. Kamalapuram’s opinion in this regard, it may cross-examine him at
trial. The jury is capable of evaluating whether his opinion is persuasive in light of all other
evidence and testimony. In any event, there is no indication that his opinion is
unsupported by his extensive experience analyzing test results and evaluating product
quality.� See Kudabeck v. Kroger Co., 338 F.3d 856, 862 (8th Cir. 2003) (“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.” (quoting Daubert, 509 U.S. at 596)).
Fifth, and finally, London Luxury claims Mr. Kamalapuram evaluated gloves based
on their color and determined that certain gloves that appeared in photographs were not
the same as ones that were tested. As a preliminary matter, the Court finds Mr.
Kamalapuram qualified to opine on the various color codes used by glove manufacturers
due to his extensive experience as a glove buyer and seller. He may therefore testify as
to his opinion that gloves that appeared to be different colors (cobalt, regular blue, or sky
blue) were likely not from the same production lots or factories. Disagreement with an
expert’s opinion is not a valid basis to exclude it. Therefore, London Luxury’s Motion to
Exclude the Testimony of Mr. Kamalapuram is DENIED.
12
D. Mr. Ryan Siskey (Doc. 229)
London Luxury has designated Mr. Ryan Siskey as an expert on industry standards
for facilities that produce medical devices, such as nitrile gloves, as well as on regulatory
and compliance issues surrounding medical devices. He has worked with clients and
regulators to design and conduct quality testing on various forms of PPE to determine
whether they conform to industry performance specifications. In particular, he has
conducted glove testing in support of manufacturing clients seeking regulatory approval
for their PPE products. He is also a certified auditor for quality management systems and
has participated in and led standards development for testing methods for medical
devices. His private consulting services focus on assisting medical device manufacturers
with regulatory and compliance hurdles, devising protocols to address failing products,
assessing gaps in quality, and dealing with internal and external audits. The Court finds
Mr. Siskey well qualified to offer expert opinions in these areas.
The Court also finds that Mr. Siskey’s testimony will help the jury understand the
sorts of regulatory standards that glove manufacturers must meet to pass factory audits,
like the ones Walmart required. He will assist the jury in assessing whether London Luxury
and its manufacturing partners followed accepted industry protocols in response to failing
test scores on certain glove samples. He opines that London Luxury and its partners
behaved in a manner typical for the industry when confronted with a report of a nonconforming product. He further opines that Walmart did not behave according to industry
standards when the company ignored the results of at least one root-cause investigation
13
and did not allow London Luxury enough of an opportunity to address the root cause of
the problem and take corrective action.
Walmart first objects to Mr. Siskey’s extensive discussion in his expert report about
ISO 13485, which Walmart contends is not in dispute in this case. “ISO” stands for
“International Organization for Standardization.” (Doc. 231-1, p. 58). London Luxury
contends that Mr. Siskey’s discussion of this international standard is relevant to the jury’s
understanding of the requirements a glove manufacturer must adhere to when producing
medical-grade products, including implementing quality management systems and riskmanagement protocols. The Court agrees with London Luxury that Mr. Siskey’s testimony
provides relevant insight into the manufacturing process for medical devices and
highlights for the jury the various quality control procedures that international standards
require.
Next, Walmart contends that Mr. Siskey’s analysis of the manufacturing facilities
at issue is deficient because he did not consider the repackaging facility, MNA Gloves,
which London Luxury used for a period of time and whose products or processing are
accused of testing failures. The Court finds that Mr. Siskey’s analysis of certain factories
and their quality assurance procedures, namely Careglove and Mercator,1 are relevant to
Walmart claims Mr. Siskey mislabeled two factory audits as “passing.” Walmart claims
they failed inspection. London Luxury responds that the meaning and significance of
Walmart’s “passing” rating is in dispute, and there is evidence that Walmart approved
manufacturers to continue producing goods despite receiving an “orange” or “halt
production” rating. See Doc. 289, p. 13. In light of this factual dispute, the Court finds Mr.
Siskey’s reliance on and citation to “passing” factory audits to be reliable or trustworthy in
an evidentiary sense and therefore appropriate to present to the jury. Walmart is free to
cross-examine Mr. Siskey regarding the factual assumptions on which he based his
1
14
the matters before the jury for decision. The omission of MNA Gloves, whether purposeful
or not, is a proper topic for cross-examination. The fact that Mr. Siskey was not asked by
London Luxury to consider MNA Gloves does not mean he should be prohibited from
testifying about the facilities he did review and consider.
Relatedly, Walmart criticizes Mr. Siskey’s focus on failing test results from 2021
while ignoring the failing test results from 2022. However, in London Luxury’s view,
Walmart canceled the parties’ contract in 2021, so only the 2021 test results are relevant,
and that is why only those results were provided to Mr. Siskey. On the surface, it does
seem problematic that Mr. Siskey was only provided with some failing test results and not
others in performing his analysis. But London Luxury’s reason for doing this is as least
arguable, and Walmart’s objection goes to the opinion’s weight and credibility, rather than
its admissibility. The Court finds that, on balance, Mr. Siskey’s analysis of the test results
he did consider is reliable or trustworthy in an evidentiary sense and will likely assist the
jury in understanding of how failing tests are generally handled in the industry and were
handled by the manufacturers in this case. Walmart is free to cross-examine Mr. Siskey
and point out his failure to consider other failing test results from 2022.
Finally, Walmart objects to Mr. Siskey opining about the unreasonableness of
Walmart’s actions in deciding not to proceed with the London Luxury contract after a
certain number of product failures came to light. Certainly, Mr. Siskey is not an expert in
Walmart’s internal policies and procedures and is not permitted to speculate as to what
opinion.
15
factors motivated Walmart’s decision-making with respect to this contract. However, given
Mr. Siskey’s twenty years of consulting experience in the PPE industry and his familiarity
with the development and implementation of medical device manufacturing, testing, and
quality standards, the Court is persuaded that he is competent to provide opinion
testimony as to whether Walmart’s decision to cancel the contract when it did, given the
test results and corrective actions taken up until that point, was generally in line with the
usual practices of buyers in the medical device industry. Mr. Siskey’s opinion is grounded
in his experience and is a plausible one. If Walmart believes the facts he considered in
forming his opinion were incomplete or untrue, Walmart may point those discrepancies
out to the jury to undermine the credibility of his opinions. See Bonner, 259 F.3d at 929–
30. Therefore, Walmart’s Motion to Exclude the Testimony of Mr. Siskey is DENIED.
E. Dr. Robert N. Phalen (Doc. 233)
London Luxury designated Dr. Robert N. Phalen as an expert on the laboratory
testing of nitrile gloves. He runs his own laboratory where he researches the performance
of disposable nitrile gloves for protection against biological and chemical agents. Over
the course of his career, he has conducted “thousands of glove integrity tests, including
tensile strength, elongation at break, and water-leak testing.” (Doc. 235-1, p. 5). The Court
finds that he is experienced in both conducting such testing and interpreting its results,
and Walmart does not disagree that he is qualified to opine on these matters.
Walmart objects to Dr. Phalen’s conclusion that the third-party test results he
analyzed pertained to gloves made in factories that either actually shipped to Walmart or
were intended to ship to Walmart. Dr. Phalen assumed in his product testing that
16
Careglove and Mercator actually manufactured the gloves in the test reports that he was
provided; he opined, generally, about the quality of these two factories and their products.
In Walmart’s view, Dr. Phalen improperly assumed as true a disputed fact, namely, the
manufacturing sources of London Luxury’s gloves. On balance, the Court agrees with
London Luxury that if there is credible evidence to suggest that Careglove and Mercator
actually manufactured the gloves, then Dr. Phalen’s testimony should not be excluded.
Instead, the jury should be given an appropriate limiting instruction reminding them that
Dr. Phalen made certain baseline assumptions about the factory origins of the gloves that
were tested, and his analysis of those tests and opinions about those facilities is only
relevant if the jury ends up agreeing with those assumptions—i.e., that the gloves
described in the tests were shipped to Walmart or intended to be shipped to Walmart by
Careglove and Mercator. See Synergetics, Inc. v. Hurst, 477 F.3d 949, 956 (8th Cir. 2007)
(“[M]ere disagreement with the assumptions and methodology used does not warrant
exclusion of expert testimony.”).
Next, Walmart objects that Dr. Phalen’s opinions amount to a conclusion that
gloves that fail independent product testing are nonetheless a “quality product.” Having
reviewed Dr. Phalen’s report, the Court does not find that he made such a sweeping
claim. Instead, he explains possible reasons for failing test scores in various categories,
based on his laboratory experience and familiarity with manufacturing and testing
conditions. He did not wave away failing test scores but instead attempted to
contextualize them, which is helpful evidence for the jury as it decides whether London
17
Luxury materially breached the contract in a manner that substantially impaired the
performance of the contract as a whole.
Walmart’s last objection to Dr. Phalen’s testimony is that the thirty-five test reports
he lists in a table in his report include some revisions of earlier test reports, rather than
thirty-five unique tests. Walmart therefore contends that the table listing thirty-three out of
thirty-five “passing” reports is misleading. In addition, Walmart complains that Dr. Phalen
failed to mention the fact that some of the test reports he reviewed did not specifically
mention either of the parties by name on the face of the reports or list particular lot
numbers for the gloves that were tested. The Court has reviewed the table at issue and
finds that Dr. Phalen acknowledged that it contained both unique tests and “test-report
revisions that might contain the same test results as a prior version.” (Doc. 235-1, pp. 21–
22). As for whether the table itself is confusing, the Court agrees with Walmart that
viewing the table in isolation, without the benefit of Dr. Phalen’s introductory comments,
could lead jurors to falsely believe that Dr. Phalen evaluated thirty-five unique product
tests. The Court therefore instructs London Luxury’s attorneys to make clear to the jury
the reality of the testing situation and not to suggest that there were thirty-five unique
tests. Further, to the extent London Luxury intends to display this table to the jury, it must
be modified to indicate which of the line-items in the list were unique tests and which were
“test-report revisions.”
Finally, with respect to Walmart’s argument that the test reports are unreliable
because, in some cases, they do not mention Walmart or London Luxury’s names or
identify specific lot numbers, the appropriate remedy is not to exclude the test reports and
18
Dr. Phalen’s interpretation of them out of hand. Instead, the parties are instructed to
confer about the authenticity and admissibility of each individual test report at issue, and
the Court will reserve ruling until either party attempts to introduce any such report into
evidence at trial. Save and except for the Court’s comments and instructions above
