MEMORANDUM AND ORDER
BEATTY, Magistrate Judge:
On June 17, 2022, Third-Party Plaintiff Hydrochem, LLC filed a motion to exclude
the expert opinions of James Ungart, Third-Party Defendant Miller Environmental’ s
retained expert witness (Doc. 130). Miller Environmental filed a response in opposition
(Doc. 140), and Hydrochem filed a reply (Doc. 145). Also on June 17, Miller
Environmental filed a motion to exclude the expert opinions of Russell Ogle,
Hydrochem’s retained expert (Doc. 133). Hydrochem filed a response in opposition (Doc.
138) and Miller Environmental filed a reply (Doc. 146). On October 18, 2022, the Court
held a hearing on the motions to exclude and allowed each party to offer oral argument
in support of their respective positions. After hearing from both parties, the Court opted
to rule on the record and denied both motions to exclude. The Court outlined its reasons
on the record and provides this as a summary written order.
DAUBERT STANDARD
“A district court’s decision to exclude expert testimony is governed by Federal
Rules of Evidence 702 and 703, as construed by the Supreme Court in Daubert v. Merrell
Dow Pharms., Inc., 509 U.S. 579, 113 S.Ct. 2786, 125 L.Ed.2d 469 (1993).” Brown v. Burlington
Northern Santa Fe Ry. Co., 765 F.3d 765, 771 (7th Cir. 2014); see also Lewis v. CITGO
Petroleum Corp., 561 F.3d 698, 705 (7th Cir. 2009). Indeed, the Daubert standard applies to
all expert testimony, whether it is based on scientific competence or other specialized or
technical experience. Smith v. Ford Motor Co., 215 F.3d 713, 719 (7th Cir.
2000) (citing Kumho Tire Co., Ltd. v. Carmichael, 526 U.S. 137, 141, 119 S.Ct. 1167, 143
L.Ed.2d 238 (1999)).
Specifically, Rule 702 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. 702.1 Under Rule 702, “an expert witness may testify about a scientific issue
in contention if the testimony is based on sufficient data and is the product of a reliable
methodology correctly applied to the facts of the case.” Vandervelden v. Saint Louis Univ.,
No. 3:18-CV-1333-NJR, 2022 WL 672753, at *2 (S.D. Ill. Mar. 7, 2022).
The trial court functions as the “gatekeeper” with respect to exert testimony in
order to ensure that the testimony is both relevant and reliable. See generally Daubert v.
509 U.S. at 595, 113 S.Ct. 2786; Lees v. Carthage College, 714 F.3d 516, 521 (7th Cir.2013). In
exercising its gatekeeping function, the court must ask three questions before admitting
expert testimony: is the expert qualified, is the expert's methodology reliable, and will
the expert's testimony assist the trier of fact in understanding the evidence or determining
a fact in issue. Myers v. Illinois Cent. R. Co., 629 F.3d 639, 644 (7th Cir.2010).
However, “the key to the gate” is not the ultimate correctness of the proposed
expert’s conclusions, but is instead the soundness and care with which the expert arrived
at the opinion. Schultz v. Akzo Nobel Paints, LLC, 721 F.3d 426, 431 (7th Cir. 2013). “So long
as the principles and methodology reflect reliable scientific practice, ‘[v]igorous cross-
examination, presentation of contrary evidence, and careful instruction on the burden of
1 Federal Rule of Evidence 703 also governs expert opinions and provides:
An expert may base an opinion on facts or data in the case that the expert has been made
aware of or personally observed. If experts in the particular field would reasonably rely on
those kinds of facts or data in forming an opinion on the subject, they need not be
admissible for the opinion to be admitted. But if the facts or data would otherwise be
inadmissible, the proponent of the opinion may disclose them to the jury only if their
probative value in helping the jury evaluate the opinion substantially outweighs their
prejudicial effect.
proof are the traditional and appropriate means of attacking shaky but admissible
evidence.’” Id. (quoting Daubert, 509 U.S. at 596, 113 S. Ct. 2786).
An expert must explain the methodologies and principles that support his or her
opinion; he cannot simply assert bottom line conclusions. Metavante Corp. v. Emigrant Sav.
Bank, 619 F.3d 748, 761 (7th Cir. 2010). The trial court possesses “great latitude in
determining not only how to measure the reliability of the proposed expert testimony but
also whether the testimony is, in fact, reliable.” United States v. Pansier, 576 F.3d 726, 737
(7th Cir. 2009) (citing Jenkins v. Bartlett, 487 F.3d 482, 489 (7th Cir. 2007)) (emphasis in
original). “The critical inquiry is whether there is a connection between the data employed
and the opinion offered.” Gopalratnam v. Hewlett-Packard Co., 877 F.3d 771, 781 (7th Cir.
2017) (quotation omitted) (emphasis in original).
DISCUSSION
On October 18, 2022, the Court ruled on the record and denied both Hydrochem
and Miller Environmental’ s motions to exclude. In so doing, the Court noted that it had
carefully reviewed the briefs prior to the hearing, both Mr. Ogle and Mr. Ungart’s reports,
as well as the excerpts of their deposition testimony that had been provided as exhibits
in the briefing. The Court provides this summary order to address some of the primary
arguments advanced by the parties.
With respect to Mr. Ogle, Miller Environmental’ s primary critique was that Mr.
Ogle’s opinions amounted to bottom line conclusions and that the basis for his
conclusions was simply his credentials. Mr. Ogle is a licensed professional engineer and
has a Ph.D in Chemical Engineering, to note just a few of his academic achievements. But
as outlined on the record, this contention is without merit. Mr. Ogle’s expert report (Doc.
138-1, pp. 29-54), for example contains a detailed explanation of his opinions, of the facts
and data upon which he relies, and the methodology or process he uses to arrive at his
conclusions. Nor can there be any suggestion that Mr. Ogle did not reliably apply his
process to the facts of the case. Indeed, his report goes to great length to explain his
opinions and how he arrived at those opinions.
Miller Environmental’ s motion attacking Mr. Ogle offers a litany of arguments in
an attempt to exclude Mr. Ogle’s opinions. However, all of these arguments are non-
starters. The subject matter at issue in this dispute is highly technical and complex and in
the Court’s review of Mr. Ogle’s proffered opinions, the Court believes they will aid the
trier of fact in understanding the evidence. Nor does the Court find, as a general matter,
that Mr. Ogle’s proffered opinions invade the province of the jury or are based on
speculation and pure conjecture. Indeed, Mr. Ogle is eminently qualified to serve as an
expert, his testimony will be helpful, it is based on facts and data and he has reliably
applied his principles and methods to facts of this case.
With respect to Mr. Ungart, the primary critique of him by Hydrochem at the oral
argument was twofold: Mr. Ungart has no educational background that qualifies him to
serve as an expert witness and that there was an error or miscalculation in his opinions.
But while Mr. Ungart may not have the academic credentials that Mr. Ogle does (Mr.
Ungart is a high school graduate), he worked in the chemical cleaning industry for 18
plus years. Indeed, he worked for Hydrochem for a period of time and he has worked on
job sites and projects similar to the turn around job at issue in this case. The notion
that Daubert requires particular credentials for an expert witness is “radically unsound”
and the Rules of Evidence, “which Daubert interprets rather than overrides,
do not require that expert witnesses be academics or PhDs, or that their testimony be
‘scientific’ (natural scientific or social scientific) in character.” Tuf Racing Prod., Inc. v. Am.
Suzuki Motor Corp., 223 F.3d 585, 591 (7th Cir. 2000). Indeed, “[a]nyone with relevant
expertise enabling him to offer responsible opinion testimony helpful to judge or jury
may qualify as an expert witness.” Id. The Court believes that Mr. Ungart’s experience
and background in the chemical cleaning industry is the type of real world practical
experience in a highly technical subject matter that will be helpful to the finder of fact.
Indeed, Mr. Ungart’s expert report (Doc. 130-2, pp 1-6) makes clear that he
reviewed facts and data applicable to this case and then utilized his experience in the
field of chemical cleaning and working on similar jobs to responsibly arrive at his
opinions. Although Hydrochem critiques Mr. Ungart for not applying certain standards
provided by the National Fire Protection Association (“NFPA”), Hydrochem failed to
point this Court to any form of authority that required Mr. Ungart to specifically employ
the NFPA standards. Indeed, Hydrochem conceded as much at oral argument. Miller
Environmental’ s response in opposition provided example cases that made clear the
NFPA is merely a guide for investigations of fires or explosions and not a required
standard that must be employed (See Doc. 140, pp. 10-13).
Hydrochem also discussed an error in a mathematical calculation made by Mr.
Ungart and used this as an attack on his ability to serve as an expert. But this is an attack
on credibility, not admissibility. A challenge to an expert’s “miscalculation” or
mathematical error goes to weight of the evidence, not admissibility. Schwarz v. Nat'l Van
Lines, No. 03 C 7096, 2005 WL 8177605, at *1 (N.D. Ill. Sept. 22, 2005); Traharne v. Wayne
Scott Fetzer Co., 156 F. Supp. 2d 717, 723 (N.D. Ill. 2001) (“Factual inaccuracies are to be
explored through cross-examination and go toward the weight and credibility of the
evidence not admissibility.”).
Hydrochem’s briefing on its motion to exclude offers a litany of arguments, but all
of these arguments were covered at the oral argument (e.g., contending Mr. Ungart’s
opinions are speculative, without adequate basis, unreliable, etc.). Moreover, as noted at
the oral argument, these arguments are non-starters as they all go to the weight of the
evidence rather than admissibility.
Ultimately, after a careful review of all the briefs, expert reports, and relevant
deposition transcripts, the parties critiques of each other’s expert witnesses all go toward
the weight of the evidence, not the admissibility of the proffered opinions. Both experts
will be permitted to testify, subject to vigorous cross-examination and the jury will assess
what weight, if any, to give each of the experts and their opinions. Both Mr. Ungart and
Mr. Ogle are qualified, have utilized a reliable methodology in arriving at their opinions,
and both experts will assist the trier of fact in understanding a very technical subject
matter.
CONCLUSION
For the reasons outlined on the record at the October 18th motion hearing and for
the reasons outlined in this Memorandum and Order, Hydrochem’s motion to exclude
the expert opinions of James Ungart (Doc. 130) and Miller Environmental’ s motion to
exclude the expert opinions of Russell Ogle (Doc. 133) are DENIED.
IT IS SO ORDERED.
