FACTUAL & PROCEDURAL BACKGROUND
This case arises from the Deepwater Horizon oil spill in the Gulf of Mexico in
2010 and the subsequent cleanup efforts of the Gulf Coast. On January 11, 2013,
United States District Judge Carl J. Barbier, who presided over the multidistrict
litigation arising out of the Deepwater Horizon incident, approved the Deepwater
Horizon Medical Benefits Class Action Settlement Agreement (the “MSA”). 6
However, certain individuals, referred to as “B3” plaintiffs, either opted out of or were
excluded from the MSA. 7 Plaintiff Lathaddeus Beacham opted out of the MSA and,
accordingly, is a B3 plaintiff. 8
Plaintiff filed this individual action against Defendants on April 9, 2017 to
recover for injuries allegedly sustained as a result of the oil spill. 9 For approximately
eighteen months in 2010 and 2011, Plaintiff worked as a cleanup worker, tasked with
cleaning up oil and oil-covered debris from clean-up equipment in Pensacola, Florida,
Venice, Louisiana, and Gulf Shores, Alabama. 10 Plaintiff alleges that Defendants’
negligence and recklessness in both causing the Gulf oil spill and subsequently failing
to properly design and implement a clean-up response caused him to suffer myriad
injuries including dental pain, shortness of breath, dizziness, nausea, rashes, eye
burning and irritation, migraines, headaches, and moderate restriction result from a

personal injury damages—including damages for past and future medical expenses
and for pain and suffering—punitive damages, and attorneys’ fees, costs, and
To help support his claims that exposure to the chemicals present in the oil
spilled by Defendants caused his particular health symptoms, Plaintiff offers the
report (“Report”) and testimony of Dr. Jerald Cook. 13 Dr. Cook is a retired Navy
physician with expertise specifically as an occupational and environmental
physician. 14 Dr. Cook’s Report is not tailored directly to Plaintiff’s claims; rather, Dr.
Cook’s generic causation Report has been utilized by numerous B3 plaintiffs,
including many plaintiffs currently before this Court as well as in other cases before
other sections of this court. 15 Accordingly, Dr. Cook’s Report pertains only to general
causation and not to specific causation. 16
Defendants filed the instant Motion in limine and Motion for Summary
Judgment on September 2, 2022. In their Motion in limine, Defendants contend that
Dr. Cook should be excluded from testifying due to, inter alia, Dr. Cook’s failure to
identify the harmful level of exposure capable of causing Plaintiff’s particular injuries
for each chemical that Plaintiff alleges to have been exposed to. Because Dr. Cook

should be excluded from testifying, Defendants argue, the Court should grant their
Motion for Summary Judgment as Plaintiff is unable to establish general causation
through expert testimony, a necessary requirement under controlling Circuit
precedent. Plaintiff opposes both Motions, arguing that Dr. Cook’s Report satisfies
the Daubert standards for reliability and relevancy and, therefore, that summary
judgment is inappropriate.
A. Motion in Limine
The district court has considerable discretion to admit or exclude expert
testimony under Fed. R. Evid. 702, 17 and the burden rests with the party seeking to
present the testimony to show that the requirements of Rule 702 are met. 18 Rule 702
provides that an expert witness “qualified . . . by knowledge, skill, experience,
training or education may testify in the form of an opinion” when all of the following
requirements are met:
(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
(d) The expert has reliably applied the principles and methods
to the facts of the case. 19

Rule 702 codifies the Supreme Court’s opinion in Daubert v. Merrell Dow
Pharmaceuticals, Inc., which charges district courts to act as “gatekeepers” when
determining the admissibility of expert testimony. 20 “To be admissible under Rule
702, the court must find that the evidence is both relevant and reliable.” 21 According
to the Fifth Circuit, reliability is determined by assessing whether the reasoning or
methodology underlying the testimony is scientifically valid, while relevance depends
on whether the reasoning or methodology underlying the testimony can be properly
applied to the facts at issue. 22 The purpose of the reliability requirement is to exclude
expert testimony based merely on subjective belief or unsupported speculation. 23
To satisfy the reliability prong of the Daubert/Rule 702 analysis, a “party
seeking to introduce expert testimony must show (1) the testimony is based upon
sufficient facts or data, (2) the testimony is the product of reliable principles and
methods, and (3) the witness has applied the principles and methods reliably to the
facts of the case.” 24 To prove reliability, the proponent of the expert testimony must
present some objective, independent validation of the expert’s methodology. 25 The
objective of this Court’s gatekeeper role is to ensure that an expert “employs in the

courtroom the same level of intellectual rigor that characterizes the practice of an
expert in the relevant field.” 26
B. Summary Judgment
Summary judgment is appropriate under Federal Rule of Civil Procedure 56
“if the movant shows that there is no genuine dispute as to any material fact and the
movant is entitled to judgment as a matter of law.” 27 When assessing whether a
genuine dispute regarding any material fact exists, the Court considers “all of the
evidence in the record but refrain[s] from making credibility determinations or
weighing the evidence.” 28 While all reasonable inferences must be drawn in favor of
the nonmoving party, a party cannot defeat summary judgment with conclusory
allegations, unsubstantiated assertions or “only a scintilla of evidence.” 29 Instead,
summary judgment is appropriate if a reasonable jury could not return a verdict for
the nonmoving party. 30
If the dispositive issue is one on which the moving party will bear the burden
of proof at trial, the moving party “must come forward with evidence which would
entitle it to a directed verdict if the evidence went uncontroverted at trial.” 31 The
non-moving party can then defeat summary judgment by either submitting evidence

sufficient to demonstrate the existence of a genuine dispute of material fact, or by
“showing that the moving party’s evidence is so sheer that it may not persuade the
reasonable fact-finder to return a verdict in favor of the moving party.” 32 If, however,
the nonmoving party will bear the burden of proof at trial on the dispositive issue,
the moving party may satisfy its burden by merely pointing out that the evidence in
the record is insufficient with respect to an essential element of the nonmoving
party’s claim. 33 The burden then shifts to the nonmoving party who must go beyond
the pleadings and, “by her own affidavits, or by the ‘depositions, answers to
interrogatories, and admissions on file,’ designate ‘specific facts showing that there
is a genuine issue for trial.’” 34
The burden of proof is on the B3 plaintiffs to prove that “the legal cause of the
claimed injury or illness is exposure to oil or other chemicals used during the
response.” 35 To prove causation, the B3 plaintiffs are required to provide reliable
expert testimony. 36 “A plaintiff in such a case cannot expect lay fact-finders to
understand medical causation; expert testimony is thus required to establish
Courts use “a two-step process in examining the admissibility of causation
evidence in toxic tort cases.” 38

causation exists. 39 “General causation is whether a substance is capable of causing a
particular injury or condition in the general population.” 40 Second, if the court finds
that there is admissible general-causation evidence, “the district court must
determine whether there is admissible specific-causation evidence.” 41
causation is whether a substance caused a particular individual’s injury.” 42 If the
court finds that there is no admissible general causation evidence, it need not
consider the issue of specific causation. 43
To establish general causation, a causation expert must identify “the harmful
level of exposure to a chemical” at which physical symptoms manifest. 44 As explained
by Dr. Cook, nearly every chemical on Earth may be toxic or even fatal at a certain
level of exposure. 45 Thus, causation experts determine not only whether a chemical
is capable of causing certain health effects, but at what level of exposure do those
health affects appear. Experts, such as Dr. Cook, refer to this inquiry with the
maxim, dosis sola facit venenum, or “the dose determines the poison.” 46 This analysis
is also referred to in the Bradford Hill factors as the dose-response relationship. 47

In recognition of the importance of this step of the causation analysis, the
American Medical Association’s Guide to the Evaluation of Disease and Injury
Causation states that determining “whether the estimated dose was sufficient to
explain observed clinical effects known to be associated with the agent in question”
is the “most critical phase of the hazard evaluation process.” 48 Relatedly, the Fifth
Circuit states that this detail is one of the “minimal facts necessary to sustain the
plaintiff’s burden in a toxic tort case.” 49 Plaintiffs must provide reliable expert
testimony establishing the requisite level of exposure necessary to cause each alleged
physical harm. 50 Accordingly, failure to properly identify the level of exposure to a
particular chemical at which harmful effects occur necessarily renders a general
causation opinion unreliable and, thus, inadmissible. 51
This Court has not previously considered the May 31, 2022 version of Dr.
Cook’s Report offered here by Plaintiff. However, the Court has previously addressed
the June 21, 2022 version of Dr. Cook’s Report, finding that that subsequent version
fails to meet the Daubert standards for reliability and helpfulness to the trier of fact. 52

The Court now reviews the earlier May 31, 2022 version of Dr. Cook’s Report and
finds that it too suffers from the same flaws as the later version. 53 For the same
reasons set forth in detail in the Order and Reasons discussing the June 21, 2022
Report, the Court determines that Plaintiff has failed in his burden of establishing
the reliability and relevance of his expert’s report and finds it appropriate to grant
Defendants’ Motion in limine to exclude Dr. Cook’s Report. Plaintiff accordingly lacks
expert testimony on general causation. Without expert testimony, which is required
to prove general causation, 54 Plaintiff has failed to demonstrate a genuine dispute of
material fact regarding his claims that his injuries were caused by exposure to oil.
“When a plaintiff has no expert testimony to prove his medical diagnosis or causation
at trial, the plaintiff’s suit may be dismissed at the summary judgment stage.” 55
Thus, Defendants’ Motion for Summary Judgment must be granted as Defendants
are entitled to judgment as a matter of law due to Plaintiff’s failure to establish
