UNITED STATES DISTRICT COURT
EASTERN DISTRICT OF LOUISIANA
ROBERT LELAND REGAN, III ET AL. CIVIL ACTION
VERSUS NO. 13-2378
BP EXPLORATION & PRODUCTION, SECTION: H
INC. ET AL.
ORDER AND REASONS
Before the Court is a Motion for Summary Judgment Due to Plaintiff’s
Lack of Causation Evidence filed by Defendants BP America Production
Company; BP Exploration & Production, Inc.; BP p.l.c.; Halliburton Energy
Services, Inc.; Transocean Deepwater, Inc.; Transocean Holdings, LLC;
Transocean Offshore Deepwater Drilling, Inc.; and Triton Asset Leasing
GmbH (Doc. 65). For the following reasons, this Motion is GRANTED.
BACKGROUND
This case is one among the “B3 bundle” of cases arising out of the
Deepwater Horizon oil spill.1 This bundle comprises “claims for personal injury
and wrongful death due to exposure to oil and/or other chemicals used during
1 See In Re Oil Spill by the Oil Rig “Deepwater Horizon” in the Gulf of Mexico, on April 20,
2010, No. 10-md-02179, R. Doc. 26924 at 1 (E.D. La. Feb. 23, 2021).
the oil spill response (e.g., dispersant).”2 These cases were originally part of a
multidistrict litigation (“MDL”) pending in the Eastern District of Louisiana
before Judge Barbier. During this MDL, Judge Barbier approved the
Deepwater Horizon Medical Benefits Class Action Settlement Agreement, but
the B3 plaintiffs either opted out of this agreement or were excluded from its
class definition.3 Subsequently, Judge Barbier severed the B3 cases from the
MDL to be reallocated among the judges of this Court.4 This case was
reassigned to Section H.5
Plaintiffs Robert Leland Regan, III and Laura Guillory Regan allege
exposure to oil and dispersants starting in May 2010.6 Plaintiff Robert Leland
Regan, III claims to suffer from a host of medical conditions because of the
exposure, including syncope and collapse, dizziness, food reaction, chemical
sensitivity, toxic encephalopathy, immune deregulation, malabsorption,
dyspnea, difficulty breathing, respiratory seizures, pneumonia, wheezing,
chronic sinusitis, cough, and postnasal drip.7 Plaintiff Laura Guillory Regan
also claims to suffer from a host of medical conditions including sore throat,
sinus congestion, nasal drip, rhinitis, cough, upper respiratory illness,
bronchitis, facial pain/sinus pain, hearing loss, difficulty communicating,
memory loss, confusion, poor coping ability, depression, anxiety, cognitive

disorder, and dizziness.8 Plaintiffs assert claims under the general maritime
law of negligence, negligence per se, and gross negligence with respect to the
spill and its cleanup.9
Now before the Court is Defendants’ Motion for Summary Judgment Due
to Plaintiff’s Lack of Causation Evidence.10 In the Motion for Summary
Judgment, Defendants argue that Plaintiffs have failed to produce any expert
evidence to prove that exposure to oil or dispersants caused their alleged
injuries.11 Plaintiffs oppose.12
LEGAL STANDARD
Summary judgment is appropriate “if the pleadings, depositions,
answers to interrogatories, and admissions on file, together with affidavits, if
any, show that there is no genuine issue as to any material fact and that the
moving party is entitled to a judgment as a matter of law.”13 A genuine issue
of fact exists only “if the evidence is such that a reasonable jury could return a
verdict for the nonmoving party.”14
In determining whether the movant is entitled to summary judgment,
the Court views facts in the light most favorable to the non-movant and draws
all reasonable inferences in her favor.15 “If the moving party meets the initial

burden of showing that there is no genuine issue of material fact, the burden
shifts to the non-moving party to produce evidence or designate specific facts
showing the existence of a genuine issue for trial.”16 Summary judgment is
appropriate if the non-movant “fails to make a showing sufficient to establish
the existence of an element essential to that party’s case.”17 “In response to a
properly supported motion for summary judgment, the non-movant must
identify specific evidence in the record and articulate the manner in which that
evidence supports that party’s claim, and such evidence must be sufficient to
sustain a finding in favor of the non-movant on all issues as to which the non-
movant would bear the burden of proof at trial.”18 “We do not . . . in the absence
of any proof, assume that the nonmoving party could or would prove the
necessary facts.”19 Additionally, “[t]he mere argued existence of a factual
dispute will not defeat an otherwise properly supported motion.”20
LAW AND ANALYSIS
Plaintiffs have the burden of proving causation. “B3 plaintiffs must
prove that the legal cause of the claimed injury or illness is exposure to oil or
other chemicals used during the response.”21 “The plaintiff’s burden with

respect to causation in a toxic tort case involves proof of both general causation
and specific causation.”22 “General causation is whether a substance is capable
of causing a particular injury or condition in the general population, while
specific causation is whether a substance caused a particular individual’s
injury.”23
Here, Defendants move for summary judgment on the grounds that
Plaintiffs cannot prove that exposure to oil or dispersants was the legal cause
of their alleged injuries.24 Plaintiffs respond that they produced two expert
opinions for each Ms. and Mr. Regan.25 Both Plaintiffs had an expert opinion
produced by Dr. William J. Rea, M.D. from the Environmental Health Center
and a second opinion by Dr. Nancy A. Didriksen, Ph.D.26 “In a toxic tort suit
such as this one, the plaintiff must present admissible expert testimony to
establish general causation as well as specific causation.”27 As such, the Court
will address the admissibility of each expert opinion in turn.

BP Expl. & Prod., Inc., No. 18-9753, 2019 WL 6615504, at *11 (E.D. La. Dec. 5, 2019).
Defendants argue that Dr. William J. Rea’s expert report is inadmissible
hearsay under Federal Rule of Evidence 801 as Dr. Rea passed away before
either party could perpetuate his testimony.
Hearsay is “a statement, other than one made by the declarant while
testifying at the trial or hearing, offered in evidence to prove the truth of the
matter asserted.”28 Under the Federal Rules of Evidence, hearsay is not
admissible unless an exception applies. “Expert reports are hearsay because
they are out of court statements offered to prove the truth of the matter
asserted.”29 Dr. Rea’s testimony was not perpetuated and thus, his expert
opinion is inadmissible hearsay that does not fall within any exception. As
“hearsay evidence inadmissible at trial cannot be used to create a genuine
issue of material fact to avoid summary judgment,” Dr. Rea’s expert opinion
does not provide the evidence that Plaintiffs need.30
Even if Dr. Rea’s report were admissible, the medical records provided
fail to establish a causal connection between Plaintiffs’ alleged exposure and
their medical conditions. The Fifth Circuit uses “a two-step process in
examining the admissibility of causation evidence in toxic tort cases. First, the
district court must determine whether there is general causation. Second, if it
concludes that there is admissible general-causation evidence, the district
court must determine whether there is admissible specific-causation

evidence.”31 With respect to general causation, “[s]cientific knowledge of the
harmful level of exposure to a chemical, plus knowledge that the plaintiff was
exposed to such quantities, are minimal facts necessary to sustain the
plaintiffs’ burden in a toxic tort case.”32 Dr. Rea’s opinion does not identify a
particular chemical to which Plaintiff was allegedly exposed or the dose.33 As
such, even if the opinion were admissible, it would not suffice to create a
genuine issue of material fact with respect to their claim that their injuries
were caused by exposure to oil and dispersants.
B. Expert Opinion of Dr. Nancy A. Didriksen, Ph.D.
Defendants argue that Dr. Didriksen’s expert opinion does not address
causation. Federal Rule of Evidence 702 provides that a witness who is
qualified as an expert may testify if: (1) the expert’s “specialized knowledge
will help the trier of fact to understand the evidence or to determine a fact in
issue”; (2) the expert’s testimony “is based on sufficient facts or data”; (3) the
expert’s testimony “is the product of reliable principles and methods”; and (4)
the principles and methods employed by the expert have been reliably applied
to the facts of the case. In Daubert v. Merrell Dow Pharmaceuticals, Inc., the
U.S. Supreme Court held that Rule 702 “requires the district court to act as a
gatekeeper to ensure that ‘any and all scientific testimony or evidence

admitted is not only relevant, but reliable.’”34 All types of expert testimony are
subject to this gatekeeping.35 The party offering the expert testimony bears the
burden of proving its reliability and relevance by a preponderance of the
evidence.36
The reliability of expert testimony “is determined by assessing whether
the reasoning or methodology underlying the testimony is scientifically
valid.”37 The Court may consider several nonexclusive factors in determining
reliability, including: (1) whether the technique has been tested, (2) whether
the technique has been subject to peer review and publication, (3) the
technique’s potential error rate, (4) the existence and maintenance of
standards controlling the technique’s operation, and (5) whether the technique
is generally accepted in the relevant scientific community.38 Granted, the
reliability analysis is a flexible one and “not every Daubert factor will be
applicable in every situation.”39 As the gatekeeper of expert testimony, this
Court enjoys broad discretion in determining admissibility.40
Dr. Didriksen’s expert opinion does not meet this standard and is
inadmissible. Minimally, the Fifth Circuit has held that to be admissible, a
general causation opinion must identify the harmful level of exposure for a

chemical.41 Beyond this, the court has also held that an opinion must not only
show a “scientific knowledge of the harmful level of exposure to a chemical” but
also “knowledge that the plaintiff was exposed to such quantities.”42 Plaintiffs
were referred to Dr. Didriksen for a neuropsychological consultation and the
expert opinion focuses on their personality traits, memory, and other
behavioral qualities. The opinion does make any attempt to analyze Plaintiffs’
probable level of exposure or opine on the minimum level of exposure that could
cause Plaintiffs’ physical conditions.43 As such, Dr. Didriksen’s opinion does
not meet the minimal requirements, and therefore, her report does not provide
the evidence Plaintiffs need to prove either general or specific causation.
Beyond Dr. Rea and Dr. Didriksen, Plaintiffs have presented no other
expert opinions. In a toxic tort case like this, expert medical opinion is required
to show causation, and Plaintiffs have no admissible medical expert testimony.
Therefore, Plaintiffs have failed to create a genuine issue of material fact with
respect to their claims that their injuries were caused by exposure to oil and

dismissing Plaintiffs’ claims.
CONCLUSION
For the foregoing reasons, Defendants’ Motion for Summary Judgment
(Doc. 65) is GRANTED. IT IS ORDERED that all of Plaintiffs’ claims are
DISMISSED WITH PREJUDICE.
