EASTERN DISTRICT OF LOUISIANA

CALLEN DEMPSTER et al. CIVIL ACTION

VERSUS NO. 20-95

LAMORAK INSURANCE CO. et al. SECTION: “G”(1)

ORDER AND REASONS
In this litigation, Plaintiffs Tanna Faye Dempster, Steven Louis Dempster, Janet Dempster
Martinez, Marla Dempster Loupe, Callen Dempster, Jr., Annette Dempster Glad, and Barnett
Dempster’s (collectively, “Plaintiffs”) allege that Decedent Callen L. Dempster (“Decedent”) was
exposed to asbestos and asbestos-containing products that were designed, manufactured, sold,
and/or supplied by a number of Defendant companies while Decedent was employed by
Huntington Ingalls Incorporated (“Avondale”).1 Pending before the Court is a “Motion to Strike
Plaintiffs’ Expert Gerard L. Baril” filed by Defendant Hopeman Brothers, Inc. (“Hopeman”) and
Third-Party Defendant Liberty Mutual Insurance Company as alleged insurer of Wayne
Manufacturing Corp. (“Wayne”) (collectively, the “Hopeman Interests”).2 Defendants Foster

Wheeler, LLC and General Electric Company join the motion.3 Plaintiffs oppose the motion in
limine.4 Considering the motion, the memoranda in support and in opposition, the record, and the
applicable law, the Court grants the motion in part and denies it in part.

I. Background
In this litigation, Plaintiffs allege that Decedent was employed by Avondale from 1962 to
1994.5 During that time, Plaintiffs aver that Decedent was exposed to asbestos and asbestos-
containing products in various locations and work sites, resulting in Decedent breathing in
asbestos fibers and later developing asbestos-related cancer.6 Plaintiffs assert strict liability and
negligence claims against various Defendants.7
Decedent filed a “Petition for Damages” in the Civil District Court for the Parish of
Orleans, State of Louisiana, on March 14, 2018.8 Defendants Huntington Ingalls Incorporated,
Albert Bossier, Jr., J. Melton Garret, and Lamorak Insurance Company (the “Removing Parties”)
removed the case to the United States District Court for the Eastern District of Louisiana for the
first time on June 21, 2018.9 On January 7, 2019, this Court remanded the case to the Civil District

Court for the Parish of Orleans.10

Petition for Damages was filed in state court substituting Decedent’s heirs as Plaintiffs on January
17, 2019.11 Trial was scheduled to begin before the state trial court on January 13, 2020.12
However, on January 9, 2020, Avondale removed the case to the United States District Court for
the Eastern District of Louisiana for a second time.13 On January 28, 2020, the Court denied the

motion to remand, finding that this case was properly removed to this Court under the federal
officer removal statute.14
On February 25, 2020, the Hopeman Interests filed the instant motion in limine.15
Defendants Foster Wheeler, LLC and General Electric Company join the motion.16 On March 17,
2020, Plaintiffs filed an opposition to the instant motion.17 On May 5, 2020, the Court continued
the May 18, 2020 trial date due to COVID-19.18
II. Parties’ Arguments
A. The Hopeman Interests’ Arguments in Support of the Motion
The Hopeman Interests move the Court to issue an order excluding the testimony of
Plaintiffs’ expert in industrial hygiene, Gerard L. Baril.19 The Hopeman Interests argue that Mr.

Baril’s testimony should be excluded for two reasons.20 Additionally, the Hopeman Interests
contend that testimony regarding the Longo/Hatfield Micarta Study, upon which Mr. Baril
allegedly relied, should be excluded for three additional reasons.21

1. Objections to Mr. Baril’s Proposed Testimony
The Hopeman Interests argue that Mr. Baril’s testimony should be excluded for two
reasons: (1) Mr. Baril has no opinion as to whether the Hopeman Interests were a substantial or
significant contributing factor in causing Decedent’s lung cancer; and (2) Mr. Baril’s opinion is
solely based upon others’ studies involving the cutting of wallboards but Mr. Baril does not know
if the boards used in the studies were the same as the boards used by Hopeman at Avondale.22
First, the Hopeman Interests assert that to prevail in an asbestos case “a plaintiff must
show by a preponderance of the evidence that he had significant exposure to the product
complained of to the extent that is was a substantial factor in bringing about his injury.”23 The
Hopeman Interests contend that an expert opinion regarding causation cannot be based on a theory

that “every exposure” or “every exposure above background” contributed to the injury.24
According to the Hopeman Interests, Mr. Baril offers no opinion whether Decedent’s exposure
to Hopeman’s activities at Avondale was a “substantial contributing factor” in causing Decedent’s
lung cancer.25 Moreover, the Hopeman Interests assert that Mr. Baril does not rely upon any

25 Id. at 5.
exposure assessments, dose reconstruction or exposure models to support his opinions.26
Accordingly, the Hopeman Interests contend that Mr. Baril’s testimony should be excluded
because “he does nothing more than add duplicative testimony that Hopeman operations could
be a contributing factor to [Decedent’s] lung cancer.”27

Second, the Hopeman Interests argue that Mr. Baril’s opinions are based on unsupported
and irrelevant studies by Hayes, Hatfield, Millette and Carter concerning the cutting of Micarta
and/or Marinite wallboard.28 However, the Hopeman Interests contend that Mr. Baril previously
testified that he did not know whether this type of board was used by Hopeman at Avondale.29
2. Objections to the Longo/Hatfield Micarta Study
Additionally, the Hopeman Interests contend that Mr. Baril bases his opinions on various
work practice studies performed by Material Analytic Service, Inc. (“MAS”), including a
Longo/Hatfield Micarta Study.30 The Hopeman Interests argue that this Court should prohibit
Plaintiffs “from mentioning, referencing, or introducing any workplace simulation videos relating
to these studies or testimony based on them for at least three reasons.”31

First, the Hopeman Interests the Longo/Hatifield Micarta Study is experimental evidence
that does not depict work practices substantially similar to Decedent’s alleged exposure.32 The
Hopeman Interests assert that the study was performed in a small chamber without ventilation,

yielding higher levels of exposure that those typical of field operations.33 The Hopeman Interests
contend that field studies were available, but Plaintiffs did not provide those studies to Mr. Baril.34
Accordingly, the Hopeman Interests argue that testimony regarding the Hatfield/Longo Micarta
Study should be excluded because it is not “substantially similar” to the facts of the case.35

Second, the Hopeman Interests argue that the Longo/Hatfield Micarta Study lacks
scientific reliability.36 Specifically, the Hopeman Interests assert that the “indirect preparation
technique” used in the Longo/Hatfield Micarta Study to prepare the air filters before their analysis
by transmission electron microscopy (“TEM”) lacks scientific validity.37 The Hopeman Interests
contend that there is nothing endorsing the use of the indirect preparation technique in
circumstances similar to those presented here.38 Accordingly, the Hopeman Interests argue that
Mr. Baril’s opinions based on the Longo/Hatfield Micarta Study should be excluded because the
study is based on unreliable methodologies and techniques.39
Third, the Hopeman Interests assert that any videotape of the Longo/Hatfield Micarta

Study should be excluded because any potential probative value is substantially outweighed by
the probability that their admission will necessitate undue consumption of time, create a
substantial danger of unfair prejudice, confuse the issues and mislead the jury.40

B. Plaintiffs’ Arguments in Opposition to the Motion
In response, Plaintiffs note that the motion “is somewhat confusing.”41 Plaintiffs point out
that the Hopeman Interests do not cite an opinion of Mr. Baril that they seek to preclude.42 Instead,

Plaintiffs assert that the Hopeman Interests “fill their motion with arguments and exhibits that
have absolutely nothing to do with Gerard Baril, his methodology, or with the materials upon
which he relies.”43 Nevertheless, Plaintiffs contend that the motion in limine should be denied.44
First, Plaintiffs contend that Mr. Baril is eminently qualified to testify as an expert in this
matter.45 Plaintiffs note that Mr. Baril has over 35 years of experience as an industrial hygienist
and a Master’s Degree in Environmental Health from Hunter College.46 Therefore, Plaintiffs
argue that Mr. Baril is qualified to testify as a certified industrial hygienist and environmental
health expert regarding the release of asbestos fibers from asbestos products.47
Second, Plaintiffs contend that Mr. Baril’s opinions are reliable under Daubert.48
Plaintiffs note that Mr. Baril reviewed various depositions in this matter, including the depositions

of Decedent, Burnette Bordelon, O’Neil Duronslet, Lee Tregre, Luther Dempster, Joseph Brazan,
Michael Comardelle, and Jerry Savoie.49 Plaintiffs also note that Mr. Baril reviewed the Avondale

personnel file of Decedent and scientific literature regarding exposures during the cutting and
handling of asbestos wall panels and/or wallboards.50 Plaintiffs contend that Mr. Baril compared
the levels of exposure Decedent sustained from Hopeman’s activities to both the occupational
health standards as well as the published, scientific literature.51 Plaintiffs note that Mr. Baril cited

five studies that examined sawing of asbestos wall panels, the very issue that exists in this case
with regard to Hopeman Brothers.52 Additionally, Plaintiffs assert that Mr. Baril confirmed that
he was familiar with the fact that Hopeman cut panels made up of Marinite and Micarta.53
Plaintiffs assert that this methodology has been approved by the numerous courts, including the
Fifth Circuit.54
Third, Plaintiffs contend that a dose calculation is not required and would be impossible
in this case because a proper dose calculation would have required air monitoring on Decedent
while he was employed at Avondale.55 Plaintiffs assert that Mr. Baril has not opined that every
exposure or every exposure above background is causative, as the Hopeman Interests suggest.56

Finally, Plaintiffs submit that the tests upon which Mr. Baril relies are highly
representative of the conditions described by Decedent.57 Alternatively, Plaintiffs contend that
any dissimilarities between testing conditions and actual conditions affect the weight of the

evidence rather than its admissibility.58 Plaintiffs argue that the Longo/Hatfield Micarta Study,
one of six studies regarding the cutting of wallboard upon which Mr. Baril relied, does not lack
reliability.59 Plaintiffs assert that Mr. Baril relied on the PCM fiber counting method employed in
the study, not the TEM method.60 Alternatively, Plaintiffs submit that the TEM method is not

flawed and has been used by the Environmental Protection Agency.61 Finally, Plaintiffs state that
they do not intend to offer the videotape of the Longo/Hatfield Micarta Study at trial.62
Accordingly, Plaintiffs argue that the motion should be denied.63
III. Legal Standard
The district court has considerable discretion to admit or exclude expert testimony under
Federal Rule of Evidence 702.64 Rule 702, which governs the admissibility of expert witness
testimony, provides that an expert witness “qualified . . . by knowledge, skill, experience, training
or education,” may testify when “scientific, technical or other specialized knowledge will assist
the trier of fact to understand the evidence or to determine a fact in issue.”65 For the testimony to

be admissible, Rule 702 establishes the following requirements:
(1) the testimony [must be] based on sufficient facts or data,

64 See Gen. Elec. Co. v. Joiner, 522 U.S. 136, 138–39 (1997); Seatrax, Inc. v. Sonbeck Int’l, Inc., 200 F.3d
358, 371 (5th Cir. 2000).
65 Fed. R. Evid. 702; see also Daubert v. Merrell Dow Pharm., Inc., 509 U.S. 579 (1993).
(2) the testimony [must be] the product of reliable principles and methods, and
(3) the expert [must reliably apply] the principles and methods to the facts of the case.66
In Daubert v. Merrell Dow Pharmaceuticals, Inc., the Supreme Court held that Rule 702

requires the district court to act as a “gatekeeper” to ensure that “any and all scientific evidence
admitted is not only relevant, but reliable.”67 The court’s gatekeeping function thus involves a
two-part inquiry into reliability and relevance. First, the court must determine whether the
proffered expert testimony is reliable. The party offering the testimony bears the burden of
establishing its reliability by a preponderance of the evidence.68 The reliability inquiry requires a
court to assess whether the reasoning or methodology underlying the expert’s testimony is valid.69
The aim is to exclude expert testimony based merely on subjective belief or unsupported
speculation.70
In Daubert, the Supreme Court identified a number of factors that are useful in analyzing
reliability of an expert’s testimony: (1) whether the theory has been tested; (2) whether the theory

has been subject to peer review and publication; (3) any evaluation of known rates of error; (4)
whether standards and controls exist and have been maintained with respect to the technique; and
(5) general acceptance within the scientific community.71 In Kumho Tire Co. v. Carmichael, the
Supreme Court emphasized that the test of reliability is “flexible” and that Daubert’s list of

67 Daubert, 509 U.S. at 597; see also Kumho Tire Co. v. Carmichael, 526 U.S. 137, 147 (1999) (clarifying
that the court’s gatekeeping function applies to all forms of expert testimony).
68 See Moore v. Ashland Chem. Inc., 151 F.3d 269, 276 (5th Cir. 1998) (citing In re Paoli R.R. Yard PCB
Litig., 35 F.3d 717 (3d Cir. 1994)).

specific factors does not necessarily nor exclusively apply to every expert in every case.72 The
overarching goal “is to make certain that an expert, whether basing testimony on professional
studies or personal experience, employs in the courtroom the same level of intellectual rigor that
characterizes the practice of an expert in the relevant field.”73 The court must also determine

whether the expert’s reasoning or methodology “fits” the facts of the case and whether it will
thereby assist the trier of fact to understand the evidence—in other words, whether it is relevant.74
A court’s role as a gatekeeper does not replace the traditional adversary system,75 and “[a]
review of the caselaw after Daubert shows that the rejection of expert testimony is the exception
rather than the rule.”76 As the Supreme Court noted in Daubert, “[v]igorous cross-examination,
presentation of contrary evidence, and careful instruction on the burden of proof are the traditional
and appropriate means of attacking shaky but admissible evidence.”77 “As a general rule,
questions relating to the bases and sources of an expert’s opinion affect the weight to be assigned
that opinion rather than its admissibility.”78

The Hopeman Interests move the Court to issue an order excluding the testimony of

72 Kumho Tire, 526 U.S. at 142; see also Seatrax, 200 F.3d at 372 (explaining that reliability is a fact-

expertise and the subject of the testimony”).

Plaintiffs’ expert in industrial hygiene, Gerard L. Baril.79 The Hopeman Interests argue that Mr.
Baril’s testimony should be excluded for two reasons.80 Additionally, the Hopeman Interests
contend that testimony regarding the Longo/Hatfield Micarta Study, upon which Mr. Baril
allegedly relied, should be excluded for three additional reasons.81 The Court addresses each of

these issues in turn.
1. Objections to Mr. Baril’s Proposed Testimony
The Hopeman Interests argue that Mr. Baril’s testimony should be excluded for two
reasons: (1) Mr. Baril has no opinion as to whether the Hopeman Interests were a substantial or
significant contributing factor in causing Decedent’s lung cancer; and (2) Mr. Baril’s opinion is
solely based upon others’ studies involving the cutting of wallboards but Mr. Baril does not know
if the boards used in the studies were the same as the boards used by Hopeman at Avondale.82
The Hopeman Interests argument that Mr. Baril does not know if the boards used in the
study were the same as the boards used by Hopeman at Avondale is clearly unfounded. The

Hopeman Interests base this argument on deposition testimony Mr. Baril gave in 2011 in an
unrelated case.83 The Hayes, Hatfield, Millette and Carter studies upon which Mr. Baril relies
concern the cutting of Micarta and/or Marinite wallboard. The Hopeman Interests do not dispute
that this was the type of board used at Avondale. When Mr. Baril was deposed in this case, he
confirmed that he was familiar with the fact that Hopeman cut asbestos boards made from

Marinite and Micarta.84 Accordingly, this argument is without merit.
The Hopeman Interests also assert Mr. Baril offers no opinion whether Decedent’s
exposure to Hopeman’s activities at Avondale was a “substantial contributing factor” in causing
Decedent’s lung cancer.85 Moreover, the Hopeman Interests assert that Mr. Baril does not rely

upon any exposure assessments, dose reconstruction or exposure models to support his opinions.86
Accordingly, the Hopeman Interests contend that Mr. Baril’s testimony should be excluded
because “he does nothing more than add duplicative testimony that Hopeman operations could
be a contributing factor to [Decedent’s] lung cancer.”87
In response, Plaintiffs contend that Mr. Baril’s opinions are reliable under Daubert.88
Plaintiffs note that Mr. Baril reviewed various depositions in this matter, the Avondale personnel
file of Decedent and scientific literature regarding exposures during the cutting and handling of
asbestos wall panels and/or wallboards.89 Plaintiffs note that Mr. Baril cited five studies that
examined sawing of asbestos wall panels, the very issue that exists in this case with regard to
Hopeman Brothers.90

Pursuant to Federal Rule of Evidence 702, an expert’s testimony must be based on
sufficient facts or data. Federal Rule of Evidence 703 “requires that the facts on which the expert

relies must be reasonably relied on by other experts in the field.”91 The Fifth Circuit has
recognized that “[s]cientific knowledge of the harmful level of exposure to a [substance], plus
knowledge that the plaintiff was exposed to such quantities, are minimal facts necessary to sustain
the plaintiffs’ burden in a toxic tort case.”92 However, the law does not require plaintiffs to show

the precise level of the toxin to which they were exposed.93
In Curtis v. M&S Petroleum, Inc., a case dealing with benzene exposure, the Fifth Circuit
found that the district court abused its discretion in excluding proposed testimony of an expert
witness, Dr. Frank Stevens.94 In reaching his opinion, Dr. Stevens relied on several scientific
studies, the plaintiffs’ testimony regarding their symptoms and the work conditions, and the
design of the refinery.95 The Fifth Circuit reasoned that “the law does not require Plaintiff to show
the precise level of benzene exposure to which they were exposed.”96 “Because Dr. Stevens’s
causation opinion was based on scientific knowledge that would assist the trier of fact as required
by Rule 702,” the Fifth Circuit concluded that his testimony was admissible.97

Here, Mr. Baril reviewed Decedent’s deposition testimony and the deposition testimony
of other former Avondale employees including Burnette Bordelon, Jerry Savoie, Luther
Dempster, and Michael Comardelle.98 During his deposition, Mr. Baril testified that he “reviewed

the literature to identify various types of asbestos-related activities and the exposure level
produced by those activities.”99 He summarized those materials in a document titled “Asbestos
Activities and Exposure Levels.”100 Mr. Baril referenced the following studies that documented

the levels of asbestos exposure from the cutting of wallboard: (1) Gobbel Hays, et al.; (2)
Hatfield/Longo, et al.; (3) Cross, et al.; (4) Mount, et al.; (5) Millette, et al.; and (6) Harries, et
al.101
The above evidence demonstrates that Mr. Baril’s proposed testimony is based on
sufficient facts and data, and it is the product of reliable principles and methods. Nevertheless,
the Hopeman Interests assert that Mr. Baril’s testimony should be excluded because he has not
provided any quantitative or qualitative assessment of Decedent’s alleged exposure to asbestos
via Hopeman operations, such as air monitoring, or calculated Decedent’s cumulative dose.102
The law does not require Plaintiffs to show the precise level of asbestos to which Decedent was
exposed.103 Mr. Baril’s proposed testimony is based on scientific knowledge of the harmful level

of exposure to asbestos and evidence indicating that Decedent was exposed to such harmful
levels.104 Moreover, “[a]s a general rule, questions relating to the bases and sources of an expert’s
opinion affect the weight to be assigned that opinion rather than its admissibility and should be
left for the jury’s consideration.”105 The Hopeman Interests can raise this issue on cross-

examination.
The Hopeman Interests also argue that an expert opinion regarding causation cannot be
based on a theory that “every exposure” or “every exposure above background” contributed to
the injury.106 In response Plaintiffs do not dispute that the “any exposure above background”

theory is unreliable.107 Instead, Plaintiffs contend that Mr. Barial’s opinion regarding Decedent’s
exposures to the Hopeman Interests’ asbestos products are not based on an “any exposure above
background” theory.108
The “every exposure” or “every exposure above background” theory “represents the
viewpoint that, because science has failed to establish that any specific dosage of asbestos causes
injury, every exposure to asbestos should be considered a cause of injury.”109 Numerous courts
have excluded expert testimony based on this theory finding that the theory is unreliable as it is
not supported by sufficient facts or data.110 Plaintiffs do not argue that this theory of liability is
reliable.111 Instead, Plaintiffs contend that Mr. Baril’s opinion is not based on this theory.

However, during his deposition, Mr. Baril testified that “[a]ny exposure above background level

“every exposure to asbestos above background significantly contributes to development of a
disease.”113 Therefore, to the extent Mr. Baril is advocating for an “every exposure” or “every

exposure above background” theory of causation, such testimony is excluded.
2. Objections to the Longo/Hatfield Micarta Study
The Hopeman Interests contend that any evidence or testimony based on the
Longo/Hatfield Micarta Study should be excluded for three reasons.114 The Court addresses each
of these arguments in turn.
First, the Hopeman Interests the Longo/Hatifield Micarta Study is experimental evidence
that does not depict work practices substantially similar to Decedent’s alleged exposure.115 The
Hopeman Interests contend that field studies were available, but Plaintiffs did not provide those
studies to Mr. Baril.116 In response, Plaintiffs submit that the tests upon which Mr. Baril relies are
highly representative of the conditions described by Decedent.117 Alternatively, Plaintiffs contend

that any dissimilarities between testing conditions and actual conditions affect the weight of the
evidence rather than its admissibility.118 As discussed above, “questions relating to the bases and
sources of an expert’s opinion affect the weight to be assigned that opinion rather than its

admissibility and should be left for the jury’s consideration.”119 Similarly, dissimilarities between
testing conditions and actual conditions affect the weight of the evidence rather than its
admissibility.120 The Hopeman Interests may pursue this issue on cross-examination.

Second, the Hopeman Interests assert that the “indirect preparation technique” used in the
Longo/Hatfield Micarta Study to prepare the air filters before their analysis by transmission
electron microscopy (“TEM”) lacks scientific validity.121 The Hopeman Interests contend that
there is nothing endorsing the use of the indirect preparation technique in circumstances similar
to those presented here.122 In response, Plaintiffs assert that Mr. Baril relied on the PCM fiber
counting method employed in the study, not the TEM method.123 Accordingly, this issue appears
to be moot.
Third, the Hopeman Interests assert that any videotape of the Longo/Hatfield Micarta
Study should be excluded.124 In response, Plaintiffs state that the do not intend to offer the
videotape of the Longo/Hatfield Micarta Study at trial.125 Therefore, this issue also appears to be

moot.

IT IS HEREBY ORDERED that the Hopeman Interests’ “Motion to Strike Plaintiffs’
Expert Gerard L. Baril’”!?° is GRANTED IN PART and DENIED IN PART. The motion is
GRANTED to the extent it seeks to exclude testimony that any exposure to asbestos above
background significantly contributed to Decedent’s disease. The motion is DENIED in all other
respects.
