GHARDA USA, INC. AND GHARDA CHEMICALS, LTD., Appellees
On Appeal from the 55th District Court
Harris County, Texas
Trial Court Case No. 2004-67993
DISSENTING OPINION
I respectfully dissent. CSI’s case depended heavily on a series of
interdependent expert opinions, none of which was sufficient on its own to support
a conclusion that the cause of the fire was a spontaneous ignition of fumes
occurring due to EDC contamination in chemical products marketed and sold by
the Gharda entities. More importantly, even taken together, the expert opinions did
not rest upon a reliable basis sufficient to justify their admission into evidence.
The district court correctly concluded that these opinions could not support the
jury’s verdict. Even if the remaining factual circumstantial evidence were
sufficient to support a conclusion that the fire was started by some defect in the
Gharda product, there was no evidence to demonstrate what that defect was, how it
came about, or who was responsible for it. Accordingly, I would affirm the district
court, which correctly rendered a take-nothing judgment.
I. Supplemental background
The majority opinion advocates for the admissibility of the challenged
expert opinions without adequately acknowledging and addressing the arguments
about their deficiencies. To put the issues presented in their proper context, the
following summary provides additional detail about the key expert opinions at
issue and the criticisms interposed by the Gharda entities.
A. Sammy Russo, fire investigator
CSI describes Sammy Russo as its “fire origin expert.” His background and
qualifications as a fire investigator are not at issue in this appeal, but the reliability
of his methodology and resulting opinions are. After CSI’s trial counsel had
already preliminarily determined and informed Gharda that “container drums of
2
Chlorpyrifos Technical, manufactured and/or distributed by Gharda USA . . . were
located in the probable location of the fire’s origin and may have been the cause of
the fire,” the same lawyers hired Russo, who subsequently made his first visit to
the CSI facility six days after the fire without actually entering the facility at that
time. He first physically entered the facility during his second visit, nine days after
the fire. During that inspection, Russo wore a full-body protective suit to avoid
exposure to chemicals on the premises.
Russo claimed to use a methodology known as NFPA 921 to perform his
investigation.1 Despite being referenced repeatedly at trial and in the parties’
briefing, a copy of NFPA 921 does not appear to have been made part of the
appellate record. It was fundamentally CSI’s burden to demonstrate that its
proffered expert opinion testimony rested upon a reliable basis. See E.I. du Pont
de Nemours & Co. v. Robinson, 923 S.W.2d 549, 556 (Tex. 1995).2 Based on
1
In a general sense, NFPA 921 has been accepted by many courts as a
scientifically reliable methodology for investigating the cause and origin of a
fire. See, e.g., Proffitt v. State, No. 01-02-00692-CR, 2003 WL 22512074
(Tex. App.—Houston [1st Dist.] Nov. 6, 2003, pet. ref’d) (mem. op.). See
generally 5 DAVID L. FAIGMAN ET AL., MODERN SCIENTIFIC EVIDENCE: THE
LAW AND SCIENCE OF EXPERT TESTIMONY § 39.9 (2011–2012 ed.); REPORT
OF THE TEXAS FORENSIC SCIENCE COMMISSION: WILLINGHAM/WILLIS
INVESTIGATION, at 14 (2011) (hereinafter, WILLINGHAM REPORT), available
at http://www.fsc.state.tx.us/documents/FINAL.pdf (recognizing NFPA 921
as expressing the “contemporary standard of practice”).
2
It is also CSI’s burden as appellant to bring us a complete record supporting
its request that we reverse the judgment of the trial court based upon our de
3
various observations, Russo developed a hypothesis that the fire started in the
southwest quadrant of the building, where the hot box was located.3 The factors
that he said led to his hypothesis included the general location of the fire’s origin
as indicated by helicopter news video footage, reports from firefighters who
novo review of the trial court’s rendition of a JNOV. The relevant text of
NFPA 921 was made available to the trial court, but it has not been provided
to us, which makes it difficult to conclude, as the majority has, that Russo
complied with NFPA 921 in its material particulars so as to provide a
reliable basis for his opinions. CSI relies on Russo’s assertion that he
followed NFPA 921 as support for the supposed reliability of his method,
but, as acknowledged by the panel majority, the Gharda entities disputed
whether Russo’s method actually adhered to the guidelines of NFPA 921.
The majority nevertheless accepts and relies upon Russo’s assertions that he
actually followed NFPA 921’s procedures, despite the fact that the record
contains no basis upon which the majority could make that determination de
novo. In particular, the majority entirely fails to address one of the
criticisms of Russo’s supposed adherence to NFPA 921: the requirement that
a hypothesis about the location of a fire’s origin be confirmed by
identification of an ignition source before an opinion can be reliably formed
about cause and origin.
3
In its appellate brief, CSI characterized Russo’s opinion at trial more
broadly, stating that his opinion was that “the physical evidence was
consistent with a low-order explosion within the hot box from an ignitable
vapor, and fire originating from the hot box in the southwest quadrant of the
building.” The record citations provided in support of this characterization
confirm only that Russo claimed to follow the guidelines of NFPA 921, that
he opined that “[e]verything that [he] looked at [was] consistent with it
being a very low order pressurization of the box . . . that’s consistent with
the damage that’s here,” and that there was a “fire that emanated from the
hot box and went to other areas of the building.” At the pretrial Robinson
hearing, Russo affirmatively disclaimed offering an opinion about the cause
of the fire—he confined his proposed opinion only to the location of its
origin. He specifically stated, “I don’t think I was tendered to render a
cause. I was tendered to render an origin.”
4
entered the northwest quadrant and reported fire to their right, fire patterns leading
away from the hot box and the absence of fire patterns leading toward the hot box,
damage to the hot box including doors and hinges which appeared to have been
“blown open” or “pushed open,”4 a “V” burn pattern on the wall behind the hot
box, and the appearance that three drums inside the hot box looked different than
the others and showed signs of very hot burning.
As described by Russo, the NFPA 921 investigation procedure contemplates
the development of a preliminary hypothesis that must then be evaluated to “ensure
it has scientific merit.” Russo specifically agreed that in order to test his
hypothesis, he would need “some testing that would show under the circumstances
involved, whatever was in this barrel would be something that could be a source of
an ignitable vapor.” After the hypothesis had been tested, then an opinion of fire
origin and cause could be developed.5
4
Russo testified at trial: “Once I saw the hot box, I saw that the hinges had
been – and I’m going to use the term ‘blown open,’ but they’re pushed open.
Okay? That’s a more accurate description.”
5
Relevant portions of NFPA 921 quoted during the Robinson hearing confirm
these aspects of the protocol. The quoted portions of NFPA 921 provide that
the determination of the cause of a fire “requires the identification of those
circumstances and factors that were necessary for the fire to have occurred,”
including but not limited to the “presence of a competent ignition source, the
type and form of the material first ignited and the circumstances or human
actions that allowed the factors to come together.”
5
Russo did not affirmatively testify that any scientific analysis performed by
him led to or confirmed a conclusion that a “low-order explosion within the hot
box from ignitable vapor” either happened or was even physically possible.
Instead, to confirm those conclusions, Russo suggested that additional experts be
engaged. He specifically recommended that an electrical engineer be engaged to
inspect electrical components removed from the hot box for mechanical or
electrical malfunction.6 The electrical engineer retained by CSI’s trial counsel for
this purpose concluded that whatever might have ignited a fire in the hot box, it
was not an electrical or mechanical source. Therefore, still another opinion was
required to explain how the fire could have started inside the hot box.
B. Dr. Andy Armstrong, chemist
Another one of the supplemental experts suggested by Russo was chemist
Dr. Andy Armstrong. Russo’s objective in recruiting Dr. Armstrong was described
by CSI as being “to determine a testing protocol because there was no product left
in the drums to test post-fire.”7 The “protocol” developed by the experts hired by
6
The engineer presented as CSI’s witness to inspect for mechanical or
electrical malfunction was Roger Owen. Owen testified that “[i]t was pretty
obvious that you had a fire in the oven,” and his task was to determine
whether the cause was “electrical or mechanical or something else.”
7
Although CSI’s testing protocol was premised on the assertion that the
experts had no other means to test the Gharda product, there were samples
from several other sources that they chose not to investigate. There were
burned remains found in some of the Gharda drums after the fire, but CSI’s
6
CSI’s counsel involved taking the empty Gharda drums and placing them—
13 days after the fire—into “overpacks” containing a charcoal badge8 designed to
capture materials present in the air.9 In his deposition, Dr. Armstrong admitted that
the vapors collected by the badge test could have come from a number of sources,
including the decomposition of the Gharda product (the chlorpyrifos technical),
byproducts of the fire, and the surrounding air in the area of the Houston Ship
Channel. At trial, Russo described the testing as follows:
experts chose not to test those samples. The CSI experts also chose not to
test for EDC contamination two unburned chlorpyrifos drums that came
from the same shipment as those destroyed in the hot box. The Gharda
entities tested the contents of those drums and found their EDC levels to be
within product specifications. There were also retained Gharda samples
from the same batch of chlorpyrifos, but CSI’s experts chose not to test
those, either. The Gharda entities’ tests on those retained samples showed
that none of the chlorpyrifos retains had excess EDC.
8
Dr. Armstrong explained that these “3M industrial hygiene exposure
badges” were “basically a charcoal substrate that has a personnel monitor,”
derived “from the world of industrial hygiene where you would take it out of
the container, pin it on your label and wear it all day to see what you're
exposed to.”
9
Both CSI and the majority suggest that the Gharda entities agreed to,
cooperated with, or at least acquiesced in the testing “protocol” developed
by Russo and Dr. Armstrong. There is no evidence that investigators at the
site on behalf of the Gharda entities were anything more than passively
aware of the tests performed on behalf of CSI. More importantly, the
alleged agreement or acquiescence of other investigators does not substitute
for a demonstration by CSI that its testing methodology was reliable.
7
. . . When you have a coat type of material, it tends to
absorb chemicals. So what we did was take each drum out
individually out of the hot box.
We developed a numbering system from left to right,
TF-1 being top front 1. It’s not a – you know, we used the most
complicated thing for us arson investigators.
And we took one drum at a time and we placed it into an
overpack, which is a larger drum that will seal. We put the full
contents of it, the bits and pieces of the drum, placed it in there.
And on top of each drum, we had a charcoal canister. Charcoal
absorbs hydrocarbons. It absorbs vapors.
These are sealed containers.
...
. . . [The charcoal canister has] got a layer of charcoal.
It’s got badge type of device in there. . . . [I]t comes sealed. So
there’s no – no contamination.
What we did was place a drum in the overpack, pull the
seal. We did one sample at a time so we didn’t run the risk of
mixing up, you know, drums or containers. Labeled each one
individually, popped the seal and put the – put the lid on the
overpack and allowed this to sit until we removed the samples
from the overpack.
...
. . . [The] charcoal badge . . . functions by passive
absorption. When it’s exposed to vapors – chemically, vapors
move from a higher concentration to, in this instance, no
concentration or a lower concentration and it saturates the
badge.
This is then subsequently removed and there is a little
seal that you place over this and this is sent to a testing
laboratory where they analyze the contents.
8
We didn’t open these until we put them in the drum
because we didn’t want to sample the air space within the –
within the building. So we were very careful to do that – this is
the last step before we put the seal on the drum.
The virgin unburned Gharda product that was contained in the drums before
the fire had decomposed or degraded before the vapor samples were collected.
Thus, the badge testing was performed on vapors “found or absorbed into each
badge” during the time the badges were exposed inside the overpacks. Russo
agreed that the testing only showed relative amounts of the substances detected in
the vapors, and it was not quantitative in the sense that the testing did not quantify
how much of each detected substance was present before the fire. Nevertheless,
Dr. Armstrong endorsed this testing process as being “extremely standard” and
“the most convenient, simplest way to identify the volatiles that are associated with
the fire debris.” It was by this method that the CSI experts tested the charcoal
badges in an attempt to document the contents of the drums.
Dr. Armstrong tested the charcoal badges, describing the work he did as
analyzing “fire debris.” The results from this process, which started nearly two
weeks after the fire, detected the presence of numerous “volatile components” in
some of the overpacks used in the testing.10 One of the substances detected by the
10
Dr. Armstrong testified that his “evaluation established that there were
volatile components present in the hotbox after the fire,” and that “[t]hese
volatile components included, but [were] not limited to, toluene, EDC,
aromatic compounds, other structures other than toluene, such as . . .
9
testing was toluene, a flammable substance. Dr. Armstrong initially developed an
opinion—which CSI disclosed in discovery—that the fire was caused by
chlorpyrifos technical that was contaminated with toluene. However, subsequent
to the disclosure of this opinion, fact discovery in the case revealed that toluene
was not used in Gharda’s manufacturing processes. Dr. Armstrong testified in his
deposition that his realization that toluene “was not used in the production” and
thus “would not be present due to an impurity . . . in the chlorpyrifos” led to
“further evaluation” and his “change of position.”
With toluene contamination ruled out as a cause of the fire, Dr. Armstrong
selected a different substance detected by some but not all of the badge tests: a
solvent used to manufacture chlorpyrifos known as EDC. The badges used to test
specific drums identified as the source of the fire did not show any evidence of
EDC, but Dr. Armstrong explained that result by saying that severe burning of
those drums caused all of the EDC to evaporate. When Dr. Armstrong first
identified EDC as the substance that caught fire, he had no theory about how it
ignited. He later supplemented his opinion with his explanation that the chemicals
spontaneously combusted. He explained, “[I]t is my opinion, based on my
scientific training and experience and the literature that’s available to me,
ethylbenzene and xylenes and few other things were found in the system,
mainly a lot of pyrolysis products from the various barrels.”
10
especially the Gharda literature, that the system underwent a series of reactions
after it was melted that ultimately caused a runaway reaction.”
Importantly, Dr. Armstrong did not conduct any tests to confirm the
reliability of the badge-test protocol, nor did he conduct any tests to confirm that
EDC-contaminated chlorpyrifos could spontaneously combust under the conditions
present in the hot box. He did not determine how much EDC had to be present to
produce a spontaneous combustion or otherwise test to confirm the actual presence
of a sufficient amount of EDC contamination to start the fire. He did not review
any studies about whether chlorpyrifos could self-combust, including no review of
any studies about the effect of EDC contamination on chlorpyrifos. Instead,
Dr. Armstrong expressly assumed the fire began in the hot box and then effectively
relied on the process of elimination to deduce the cause, as illustrated during his
cross-examination at the Robinson hearing:
Q [N]o one was able to identify any source of the ignition
within the hotbox, were they?
A That is correct, to my knowledge, no one can specifically
identify a component of the hotbox that would cause
ignition.
Q And so since no one knows of any component to cause
ignition to the hotbox, you came to the conclusion it had
to be spontaneous because there’s no source of ignition,
right?
A Well, one of the premises of investigation is if you
eliminate all other sources, it has to be the one that’s left,
so yes.
11
....
Q [R]eally what you did was reverse engineer because you
took the idea it had to be in the hotbox because that’s
what these fire and origin guys say; and so if the only
thing is in there, then it has to be the chlorpyrifos, right?
A That’s – except for the reverse engineering, that’s very
logical.
Q And then if there’s no source of ignition in there, then,
well, it’s just got to just self-ignite, right?
A Yes, sir, that is – the logic follows very nicely. I like
your logic.
Q And you don’t have to – then you did not perform any
test to figure out whether or not there was, in fact,
enough EDC in there or even how much EDC it would
have to have in it in order for this spontaneous
combustion to have or even perform any test in order to
support the position that you’re taking. You just didn’t
do any of that testing, did you, sir?
A Personally I did not test this product under those
conditions. I relied upon the analytical data, the
published literature from other sources to provide that
information.
Indeed, Dr. Armstrong dismissed the notion that testing played any meaningful
function in his role as a retained expert witness for the case. He testified that
“running a couple of experiments just to say, ‘I ran an experiment,’ I don’t believe
is necessary, fruitful or beneficial. Science must rely on independent evaluation of
the phenomenon that we are discussing. And it’s simply very, very
straightforward.”
12
Although Dr. Armstrong produced the badge tests as his evidence that EDC
was detected in the air trapped inside the “overpacks,” and he relied upon those
tests to deduce that the fire was caused by excess EDC present in the chlorpyrifos
drums, the foregoing analysis did not enable him to offer his own expert opinion
that an amount of EDC sufficient to cause a spontaneous combustion was actually
present in the Gharda product. In an attempt to fill that analytical gap, CSI turned
to another expert witness, Dr. Nick Cheremisinoff.
C. Dr. Nick Cheremisinoff, chemical engineer
CSI retained Dr. Cheremisinoff to review Gharda’s manufacturing process
and to provide expert testimony in support of the theory, which could not be
confirmed by the badge testing, that the drums of chlorpyrifos were contaminated
by excessive amounts of EDC. Based on his judgment that Gharda’s
manufacturing process was very complex and labor intensive, he concluded that it
was “within the realm of probability” and “possible” that such EDC contamination
had occurred.
Dr. Cheremisinoff expressly assumed that the fire was caused by the
chlorpyrifos, and he admitted that he did not know how it was ignited. He
conducted no tests to support his opinion, and he relied upon no peer-reviewed
studies to support his criticisms of the Gharda manufacturing process. He did not
base his opinion on any evidence of actual EDC contamination. He reviewed
13
Gharda’s written manufacturing protocols, but he never personally observed
Gharda’s plant or any of its manufacturing procedures.
II. Analysis
Although the panel majority refers to the district court’s discretion with
respect to evidentiary matters, this is an appeal from the trial court’s order granting
JNOV, which we review de novo under a no-evidence standard. See City of Keller
v. Wilson, 168 S.W.3d 802, 823 (Tex. 2005); Johnson v. Methodist Hosp., 226
S.W.3d 525, 528 (Tex. App.—Houston [1st Dist.] 2006, no pet.). On appeal we
apply the same standards of legal and factual sufficiency that would apply to any
civil dispute and which presumably informed the district court’s consideration of
the motion for JNOV.11
11
The Gharda entities suggest that the trial court’s ruling should be reviewed
for abuse of discretion, relying on Raynor v. Merrell Pharms., Inc., 104 F.3d
1371, 1373–74 (D.C. Cir. 1997), and Comer v. Am. Elec. Power, 63 F. Supp.
2d 927, 930–31 (N.D. Ind. 1999). The reasoning applied in these cases,
governed by federal rules of procedure, does not support abuse-of-discretion
review under the Texas rules. The trial court exercised its discretion in
connection with evidentiary rulings when it conducted the pretrial
gatekeeping hearing and when it ultimately admitted the opinions of
plaintiffs’ experts into evidence. By the time the Gharda entities filed their
motion for JNOV, the trial court’s discretion had been exercised, the jury
had rendered a verdict, and the question before the trial court was whether
the jury’s findings had any support in the evidence. See TEX. R. CIV. P. 301;
cf. Whirlpool Corp. v. Camacho, 298 S.W.3d 631, 638 (Tex. 2009) (“[A]
party may assert on appeal that unreliable scientific evidence or expert
testimony is not only inadmissible, but also that its unreliability makes it
legally insufficient to support a verdict.”). The motion for JNOV was not, as
suggested by the Gharda entities’ argument, an opportunity for the trial court
14
“An expert witness may testify regarding scientific, technical, or other
specialized matters if the expert is qualified, the expert’s opinion is relevant, the
opinion is reliable, and the opinion is based on a reliable foundation.” Whirlpool
Corp. v. Camacho, 298 S.W.3d 631, 637 (Tex. 2009) (citing, inter alia, TEX. R.
EVID. 702). “Conclusory or speculative opinion testimony is not relevant evidence
because it does not tend to make the existence of material facts more probable or
less probable.” Id. (citing TEX. R. EVID. 401 and Coastal Transp. Co. v. Crown
Cent. Petroleum Corp., 136 S.W.3d 227, 232 (Tex. 2004)). We are required to
“rigorously examine the validity of facts and assumptions” on which expert
testimony is based, “as well as the principles, research, and methodology
underlying the expert’s conclusions and the manner in which the principles and
methodologies are applied by the expert to reach the conclusions.” Id. (citing
Exxon Pipeline Co. v. Zwahr, 88 S.W.3d 623, 629 (Tex. 2002)). “[E]ach material
part of an expert’s theory must be reliable.” Id.
A. Deficiencies of individual experts
The majority opinion uncritically describes the testimony offered by each of
CSI’s putative experts, reciting each expert’s assertions, and concluding that each
expert offered admissible opinion testimony. This flawed approach completely
to revisit and revise the discretionary trial rulings that it had previously
rendered.
15
abandons the court’s “gatekeeper” function with respect to expert testimony by
dodging the Gharda entities’ criticisms of each expert and failing to critically
analyze the substance of what each expert presented to the jury. And while the
objections to each expert were legion, a central theme was that each expert
depended on some critical element that had to be supplied by another expert.
i. Russo
Sammy Russo was presented to establish that the fire originated in the hot
box.12 Although his testimony explained his hypothesis that the fire began with an
12
The majority opinion suggests that Russo was an unbiased scientific
investigator whose work was not tainted by the incentives to support CSI’s
litigation objectives, emphasizing that “Russo testified that his own
involvement in this case began as a fire-origin investigator in the immediate
aftermath of the fire and that he formed his opinions regarding the fire’s
origins in that capacity.” The majority then quotes Judge Kozinski’s opinion
on remand in Daubert and the opinion of the Supreme Court of Texas in
Robinson for the proposition that “when an expert prepares reports and
findings before being hired as a witness, that record will limit the degree to
which he can tailor his testimony to serve a party’s interests.” Robinson,
923 S.W.2d at 559 (quoting Daubert v. Merrell Dow Pharms., Inc., 43 F.3d
1311, 1317 (9th Cir. 1995)). In fact, as noted in the majority opinion and
admitted by Russo on direct examination, his involvement in the matter
began when his office received a call from the firm of the trial lawyers hired
by CSI. Accordingly, the majority misuses Daubert and Robinson to
varnish the fact that Russo was hired by CSI’s trial counsel and developed
his opinions for use in litigation. Given this fact, there is no reason to
characterize his method as “non-judicial” or to conclude that his analysis
may be reliable on such a basis. The reliability of the NFPA 921
methodology, which Russo putatively applied, is not disputed in this case.
The dispute is about whether Russo actually and faithfully applied the
methodology.
16
explosion in the hot box, he did not provide his own opinion testimony about
whether or how such an explosion actually came about. He needed to rely on some
other expert to supply that explanation.
As a threshold matter, Russo’s opinions are unreliable due to his failure to
follow NFPA 921, and his opinion testimony was properly disregarded for that
reason alone. The significance of “V” patterns relied upon by Russo to determine
the place of origin has been criticized as a “discredited” theory in this context.13
Moreover, Russo relied heavily on the characterization of the doors to the hot box
as having been “pushed open” or “blown open,” yet he provided no explanation
meeting the Robinson standard for how such a rupture could have occurred despite
the fact that after the fire the bunghole caps for the Gharda drums were found
resting undisturbed on the tops of the drums where CSI personnel had left them. 14
13
See 5 FAIGMAN ET AL., supra note 1, § 39:13, at 197; see also WILLINGHAM
REPORT, supra note 1, at 23 (“In the early 1990’s, many fire investigators
based their conclusions of origin in part on the theory that a ‘V-pattern’ on a
wall points to the origin of the fire. . . . Scientists now know that the ‘V-
pattern’ simply points to where something was burning at some stage of the
fire, not necessarily the origin.”).
14
The majority opinion quotes Russo’s testimony regarding the fact that the
bunghole caps for the Gharda drums were found after the fire, resting on top
of the drums inside the hot box. But the majority never addresses the
significance of that evidence or Gharda’s argument that it tends to disprove
Russo’s hypothesis of an explosion inside the box of such magnitude that it
“blew” open the doors. The majority opinion recites Russo’s attempt to
explain the presence of the undisturbed bung caps when he said, “You don’t
have differential pressure to blow those bungs out or give direction to this—
17
We cannot ignore such “fatal gaps in an expert’s analysis or assertions,” nor
“credit as some evidence expert opinions that are not reliable or are conclusory on
their face.” Volkswagen of Am., Inc. v. Ramirez, 159 S.W.3d 897, 912 (Tex. 2004).
Russo’s most glaring departure from the NFPA 921 methodology, and the
one that most seriously undermines the reliability of his opinion testimony, was his
failure to subject his hypothesis to meaningful testing. The hypothesis about the
place of the fire’s origin could not become a reliable opinion about the cause and
origin of the fire without a credible explanation of how the fire could have started
there.15 Russo admitted as much when he testified that if the drums inside the hot
this type of event.” Yet the majority opinion does not critically consider this
explanation, which, based on the record presented to us, has no apparent
scientific basis at all. There is no basis in the record for confirming the
reliability of the statement; we only have the fact that Russo said it.
15
It is unclear from the appellate record whether NFPA 921 would strictly
require the confirmation of a potential ignition source before a reliable
opinion can be formed about the physical origin of the fire. However, Russo
expressly agreed that in order to “really test” his hypothesis, he would “have
to have some testing that would show that under the circumstances involved,
whatever was in this barrel would be something that could be a source of an
ignitable vapor.” Other authorities also confirm the Gharda entities’
characterization of the standard as incorporating a testing requirement. See,
e.g., Fireman’s Fund Ins. Co. v. Canon U.S.A., Inc., 394 F.3d 1054, 1058
(8th Cir. 2005) (“NFPA 921 requires that hypotheses of fire origin must be
carefully examined against empirical data obtained from fire scene analysis
and appropriate testing.”); Royal Ins. Co. of Am. v. Joseph Daniel Const.,
Inc., 208 F. Supp. 2d 423, 426 (S.D.N.Y. 2002) (“The NFPA 921 sets forth
professional standards for fire and explosion investigations and provides a
six step process in which an investigator must: (1) recognize that a need
exists to determine what caused the fire; (2) define the problem; (3) collect
18
box had been filled with water or another liquid that was not ignitable, he could not
have formed an opinion that such a liquid was the source of the fire in the hot box.
The record contains no evidence that Russo (or any other CSI expert) was aware of
any test showing whether or under what conditions chlorpyrifos contaminated with
EDC could spontaneously combust. Nor did he (or any other CSI expert)
personally test the theory. Nevertheless, he offered his opinion that the fire started
in the hot box, relying solely upon the other experts who opined that this scenario
could and did happen. Russo’s opinion, standing alone, was unreliable in the
absence of supporting scientific testing. See, e.g., Whirlpool, 298 S.W.3d at 640–
42; see also Zeigler v. Fisher-Price, Inc., No. C01-3089-PAZ, 2003 WL
25686840, at *10 (N.D. Iowa July 1, 2003) (holding that in the absence of
scientific testing, a proposed cause-and-origin analysis based on an expert’s
“common-sense deductions” merely constituted “unsupported personal
observations” and thus could not be admitted into evidence); REPORT OF THE

investigators should have a thorough understanding of the importance of laboratory

As explained below, the analytical gap in Russo’s methodology was not
filled by the opinions of any of the other experts. To the extent that Russo
purported to provide an overarching opinion about cause and origin, that opinion
was only as reliable as the subsumed opinions about the cause of the fire. To the
extent that Russo’s opinion was limited, as he himself stated, solely to the location
of the fire’s origin, even that aspect of his opinion was unreliable due to
methodological failures, particularly the failure to actually test the hypothesis or
otherwise reliably confirm that a spontaneous combustion was possible under the
circumstances. See, e.g., Fireman’s Fund Ins. Co. v. Canon U.S.A., Inc., 394 F.3d
1054, 1058–59 (8th Cir. 2005) (concluding that proposed experts did not conform
to methods of NFPA 921 when experimental testing failed to produce an open
flame and the hypothesized malfunction could not be adequately explained in
theory or replicated in a test).
ii. Dr. Armstrong
Dr. Armstrong was presented to supply an explanation for how the fire could
have spontaneously ignited as a result of rapid chlorpyrifos decomposition due to
EDC contamination in the Gharda product. His analysis expressly assumed a
critical disputed fact: that the fire started in the hot box. Thus, his analysis did not
20
account for the possibility that there was no explanation for the fire’s origin within
the hot box because the fire actually started someplace else. “An expert who is
trying to find a cause of something should carefully consider alternative causes,”
and the failure to rule out other causes of the damage renders an opinion “little
more than speculation.” Robinson, 923 S.W.2d at 559.
Even assuming that the fire started in the hot box, Dr. Armstrong’s method
for identifying EDC-contaminated chlorpyrifos as the culprit was unreliable. In
the absence of physical evidence that the fire was caused by EDC contamination,
Dr. Armstrong freely admitted that he relied upon the process of elimination to
draw that conclusion. However, such reasoning cannot substitute for scientific
analysis, particularly when a critical disputed fact has been assumed—in this case,
the place of the fire’s origin—as an analytical shortcut to avoid the rigors of actual
scientific analysis. Cf. Cooper Tire & Rubber Co. v. Mendez, 204 S.W.3d 797,
807–08 (Tex. 2006) (“The universe of possible causes for the tire failure is simply
too large and too uncertain to allow an expert to prove a manufacturing defect
merely by the process of elimination.”). Such uses of the process of elimination
have been scathingly criticized in the context of developing a reliable opinion
about the cause of a fire:
The process of determining the ignition source for a fire, by
eliminating all ignition sources found, known, or believed to
have been present in the area of origin, and then claiming such
methodology is proof of an ignition source for which there is no
21
evidence of its existence, is referred to by some investigators as
“negative corpus.” Negative corpus has typically been used in
classifying fires as incendiary, although the process has also
been used to characterize fires classified as accidental. This
process is not consistent with the Scientific Method, is
inappropriate, and should not be used because it generates un-
testable hypotheses, and may result in incorrect determinations
of the ignition source and first fuel ignited. Any hypothesis
formulated for the causal factors (e.g., first fuel, ignition source,
and ignition sequence), must be based on facts. Those facts are
derived from evidence, observations, calculations, experiments,
and the laws of science. Speculative information cannot be
included in the analysis.

TECHNICAL COMMITTEE ON FIRE INVESTIGATIONS, NATIONAL FIRE PROTECTION
ASSOCIATION, NFPA 921: GUIDE FOR FIRE AND EXPLOSION INVESTIGATIONS
§ 18.6.5 (2011 ed.)); see also Somnis v. Country Mut. Ins. Co., 840 F. Supp. 2d
1166, 1172–73 (D. Minn. 2012) (allowing fire investigator to testify about the
absence of accidental causes, but excluding opinion testimony that “the absence of
an accidental explanation suggests the fire was incendiary”).
There was no physical evidence of EDC contamination in the drums
identified by Russo as the origin of the fire. Dr. Armstrong relied instead on
evidence of EDC present in other drums, and he therefore speculated that EDC had
also been present in the drums where Russo hypothesized that the fire was started.
Dr. Armstrong explained away the absence of evidence of EDC in those drums by
22
further speculating that it was entirely consumed in the fire. To the extent this
reasoning can be characterized as the discredited “negative corpus” methodology,
it does not support a reliable opinion that the fire was caused by spontaneous
combustion of chlorpyrifos contaminated with EDC.
Even to the extent that Dr. Armstrong relied upon evidence of EDC in other
drums to support an inference that EDC had been present at the source but entirely
consumed in the fire, that evidence itself resulted from an unreliable, untested,
non-peer-reviewed process of collecting airborne chemicals from charcoal patches
to identify the presence of contaminants.16 No tests were conducted to determine
whether the presence of excessive levels of EDC existing before the fire could be
reliably detected after the fire by the badge-testing method. And no tests were
16
The majority opinion relies upon Dr. Armstrong’s conclusory assertion that
the badge-testing protocol was a “tried and true” “standard test” to identify
the presence of EDC in the drums prior to the fire. As characterized by the
majority, the test was conducted “in accordance with ‘ASTM E1618,’ which
provides the standard test method for ignitable liquid residues in extracts
from fire debris samples by gas chromatography-mass spectrometry, like the
3M badges.” However, nothing in the record suggests that the CSI experts’
particular application of the charcoal badges in this case, placing them inside
“overpacks” with the chemical drums nearly two weeks after the fire, is a
method authorized or approved by ASTM E1618. Indeed, as demonstrated
by the record of the Robinson hearing, ASTM standards were invoked only
with respect to the “passive absorption elution technology” used in the
charcoal badges and the “gas chromatograph mass spectrometry evaluation
of the sample.” No peer-reviewed non-judicial ASTM standard was invoked
as an authority for Russo and Armstrong’s so-called badge-testing
“protocol” for the identification of contaminants that may have been present
before the fire.
23
conducted to verify whether a drum of chlorpyrifos contaminated with a sufficient
level of EDC to create a spontaneous combustion could be burned so thoroughly as
to eliminate all evidence of the EDC. In particular, neither Dr. Armstrong nor any
other expert was able to explain how there could have been sufficient amounts of
EDC contamination to cause spontaneous combustion of the chlorpyrifos,
considering Gharda’s tests that showed chlorpyrifos would not burn with EDC
levels up to 10%, at which level the top 60% of the drum would have been liquid.
The undisputed evidence from CSI’s own employees was that the contents of the
drums of chlorpyrifos at issue were solid at the time they were placed in the hot
box. The failure to account for this fact renders Dr. Armstrong’s methodology and
opinion unreliable. See Volkswagen, 159 S.W.3d at 912.
Additionally, the ambient air was not subjected to a badge-test to establish a
control against which the other badges could be compared. CSI’s warehouse was
located in the industrial area located around the Houston Ship Channel. The
warehouse had stored a variety of chemicals before the fire. The toxic atmosphere
present in the fire’s aftermath was vividly illustrated by the full-body protective
suit worn by Russo as a precautionary measure. To the extent the charcoal badges
placed into “overpacks” with the Gharda drums detected trace amounts of EDC
weeks after the fire, the badge-testing methodology did not even purport to
distinguish EDC that might have been present in the drums of chlorpyrifos before
24
the fire from what EDC might have been present in the ambient air. Indeed,
Dr. Armstrong himself relied on the existence of extraneous chemicals in the
ambient air to explain the badge tests’ detection of toluene that was proved not to
be part of Gharda’s manufacturing process. The badge-testing process was
therefore self-evidently unreliable due to its lack of testing, see Whirlpool, 298
S.W.3d at 640–42, and its failure to reliably account for the alternative possibility
that the badges were detecting extraneous chemicals present in the ambient air, see
Volkswagen, 159 S.W.3d at 912.
Finally, we should not ignore the evolution of Dr. Armstrong’s opinions,
which betrays the methodological flaw of beginning from a preordained conclusion
to fit a litigation strategy, and then constructing explanations to support the
conclusion. Based upon the charcoal patches’ indication that toluene was present,
Dr. Armstrong originally offered an opinion that the spontaneous ignition of
chlorpyrifos occurred due to toluene contamination. When fact discovery
subsequently confirmed that toluene was not used in Gharda’s production of
chlorpyrifos but that EDC was, he simply changed his opinion to say that EDC
contamination was the cause of the fire. When he offered these opinions, he had
no basis for knowing whether the chlorpyrifos actually was contaminated by
toluene or EDC. The fact that Dr. Armstrong was able to so easily substitute an
opinion of EDC contamination for a demonstrably incorrect initial opinion of
25
toluene contamination further undercuts the reliability of his methodology. Cf.
Comer v. Am. Elec. Power, 63 F. Supp. 2d 927, 935 (N.D. Ind. 1999) (noting that
the ability of a “so-called expert” to change his opinions based on suggestions from
counsel demonstrated that the testimony was “nothing more than unscientific
speculation” and “mere ipse dixit”).
A methodology that is designed to confirm a preconceived conclusion is the
antithesis of the scientific method and unreliable by definition. See Robinson, 923
S.W.2d at 559. The unreliability of Dr. Armstrong’s method is further
demonstrated by his studied refusal to test any of his opinions, indeed, his brazen
disdain for the suggestion that testing was “necessary, fruitful or beneficial.” See
Whirlpool, 298 S.W.3d at 640–42. Accordingly, due to these methodological
flaws, Dr. Armstrong’s opinion constituted no evidence of the cause of the fire.
iii. Dr. Cheremisinoff
Dr. Cheremisinoff merely opined that it was “quite possible” that flaws in
Gharda’s manufacturing process could result in EDC contamination. On its face,
this opinion lacks the scientific reliability necessary to be admissible under
Rule 702. That assessment is confirmed by the flaws of Dr. Cheremisinoff’s
method, which included absolutely no testing. He did not offer any reliable
opinion that the Gharda product at issue actually was contaminated. Although
Gharda had kept “retains,” samples from the actual batch of chlorpyrifos from
26
which the product at issue was taken, Dr. Cheremisinoff did not test those retains.
He did not perform any other testing to support his opinion that it was “quite
possible” that the Gharda product at issue in this case was contaminated by EDC to
any particular degree. These opinions constituted no evidence that the chlorpyrifos
placed inside CSI’s hot box was actually contaminated by EDC such that it could
have spontaneously ignited and started the fire, as assumed by both Russo and
Armstrong.
B. Deficiencies of cumulative expert opinions
The majority opinion does not consider the interrelatedness of these opinions
or the problems arising from their interdependence. Expert witnesses may rely
upon the work of other experts, but weaknesses in the reliability of an underlying
witness’s opinion infect the opinions of any other experts who rely upon it.
In this case, CSI attempted to present a case in which multiple experts
supplied different pieces of a puzzle:
 Russo, and to a lesser extent, fire marshal Harold Rice, to depict the
hot box as the likely origin of the fire, assuming that was possible;
 Armstrong to state that the fire could have started inside the hot box,
assuming that the fire actually started there and also assuming that the
product actually was contaminated; and
 Cheremisinoff to opine about the possibility of a defect in the product
present in the hot box, assuming that the product had spontaneously
combusted.
27
None of these experts offered a nonconclusory opinion with sufficient reliability to
snap a single piece of the puzzle into place. Neither Russo nor Rice could reliably
determine the fire’s origin without confirming a consistent cause. Dr. Armstrong
could not affirmatively testify about the cause of the fire without assuming that it
had originated in the hot box or without also assuming that a contaminated product
was present. Dr. Cheremisinoff could not determine that there was an actual
product defect; he could only opine that Gharda’s manufacturing process was
imperfect and, in light of his assumption that the product had spontaneously burst
into flames, that it was “quite possible” that EDC contamination occurred. None
of these assumptions turned out to be reliable, considering that each opinion—
apart from requiring bolstering from some other proffered expert’s opinion—
suffered from its own methodological flaws.
In particular, Dr. Armstrong was not justified in assuming that the Gharda
product inside the hot box was the catalyst for the fire. That assumption alone
effectively assumed the entire dispute in favor of CSI and left Dr. Armstrong in the
position of merely explaining a foregone conclusion to the best of his ability. “An
expert who is trying to find a cause of something should carefully consider
alternative causes,” Robinson, 923 S.W.2d at 559, but Dr. Armstrong did not
engage in that level of inquiry. Assuming the hot box as the place of fire origin
excused him from considering the central question that a reliable methodology
28
would have addressed: Were there alternative possible causes such that it is more
likely that the chlorpyrifos did not degrade and ignite the fire? Dr. Armstrong was
relieved from this inquiry by simply assuming that the correct location of the fire
had been identified and confining his analysis to the restricted universe of factors
existing inside the hot box, one of which had to be the cause under his assumed
scenario. His assumption did not permit a conclusion that no cause existed inside
the box. “An expert’s failure to explain or adequately disprove alternative theories
of causation makes his or her own theory speculative and conclusory.” Wal-Mart
Stores, Inc. v. Merrell, 313 S.W.3d 837, 840 (Tex. 2010) (per curiam) (citing Gen.
Motors Corp. v. Iracheta, 161 S.W.3d 462, 470 (Tex. 2005)). Because
Armstrong’s opinion as to the fire’s cause rests upon an unreliable method, it
cannot bolster Russo’s opinion as to the location of the fire’s origin, which in turn
assumes the causative element supplied by Armstrong.
Even setting aside the inherently flimsy structure of CSI’s case, with one
conditional opinion stacked upon another stacked upon another, each opinion taken
individually bears substantial indicia of unreliability. CSI’s expert case is a classic
example of opinions which were conducted and formed for the purpose of
litigation. See Robinson, 923 S.W.2d at 559. Moreover, the experts utterly failed
in their responsibility to test their theories. See Whirlpool, 298 S.W.3d at 640–42.
No testing was conducted to confirm the reliability of the method used to collect
29
samples, which consisted of placing charcoal badges in the barrels nearly two
weeks after the fire. Although CDI’s experts ultimately advanced a theory of EDC
contamination, the badge testing recorded a greater amount of toluene, a
contaminant that was not used in Gharda’s production of chlorpyrifos. No testing
was performed to exclude the possibility that the EDC, like the toluene, was
detected because EDC was present in the air at the location of the warehouse—
near the Houston Ship Channel—rather than because EDC was still present in the
product days after the fire. Dr. Armstrong did not test his theory that chlorpyrifos
contaminated with EDC could spontaneously ignite under the conditions created in
the hot box. Dr. Cheremisinoff did not test his theory that the Gharda
manufacturing process could result in EDC contamination, nor did he test the
actual product retains to determine whether they bore any evidence of
contamination.
It was CSI’s burden to prove liability at trial, and it also bore the burden of
demonstrating the admissibility of its proffered expert opinions under TEX. R.
EVID. 702. See Whirlpool, 298 S.W.3d at 639 (“The proponent must satisfy its
burden regardless of the quality or quantity of the opposing party’s evidence on the
issue and regardless of whether the opposing party attempts to conclusively prove
the expert testimony is wrong.”). To the extent that CSI argued, and the majority
opinion relies upon, assertions that it was not possible to perform tests to confirm
30
the reliability of the methods employed by its experts, that factor does not lower
CSI’s burden to prove its case, whether through appropriate expert opinion
testimony or otherwise. “Testing is not always required to support an expert’s
opinion, but lack of relevant testing to the extent it was possible, either by the
expert or others, is one factor that points toward a determination that an expert
opinion is unreliable.” Id. at 642. “If testing of critical aspects of an expert’s
testimony has not taken place either by the expert or others in the relevant
scientific or expert community, then an explanation of why it has not is an
important consideration in evaluating the expert opinions and determining whether
they are substantively more than merely the expert’s conclusory, subjective
opinion.” Id. at 642–43. The explanations provided by CSI, that testing would
have been expensive, time-consuming, inconvenient, or even dangerous, do not
mitigate the unreliability of opinions that might have been supported (or
discredited) by appropriate tests.
Given the lack of testing, the deficiencies of CSI’s expert opinions in this
case are similar to those encountered by the Supreme Court of Texas in Whirlpool
v. Camacho, and the reliability analysis should accordingly be the same. As in
Whirlpool, CSI’s experts’ theories were “developed for the litigation.” Id. at 643
(citing Robinson, 923 S.W.2d at 559, for the proposition that “opinions formed
solely for the purpose of testifying are more likely to be biased toward a particular
31
result”). The opinions and theories had not been published in any scientific
journal, treatise, or publication so they could be subjected to peer review by
someone other than experts retained by CSI in regard to the lawsuit, nor did CSI’s
experts indicate that all of the relevant theories had been accepted as valid by
relevant scientific or expert communities. See id. (citing Merrell Dow Pharms.,
Inc. v. Havner, 953 S.W.2d 706, 727 (Tex. 1997), for the proposition that the
“purpose of publication and peer review is to allow the relevant community to
comment on the expert’s theories, findings, and conclusions”). The opinion
testimony about the cause and origin of the fire was fundamentally unreliable, and
it therefore constituted no evidence to prove the Gharda entities’ liability for
damage caused by the fire.
C. Sufficiency of remaining evidence
CSI contends that even without the expert testimony, the jury’s verdict is
supported by adequate circumstantial evidence to support the claims against
Gharda. I disagree. Even if the circumstantial evidence is sufficient to support a
conclusion that the fire started in the hot box and therefore likely originated with
the Gharda product, the circumstantial evidence does not prove the causative
element necessary to hold Gharda liable for CSI’s claimed damages. As in
Whirlpool, the other evidence produced at trial and relied upon by CSI’s experts
may be consistent with and support a conclusion that fire was in and around the hot
32
box, but that evidence does prove that the fire originated as CSI’s experts said it
did. See id. (citing Mack Trucks, 206 S.W.3d at 580); see also Merrell, 313
S.W.3d at 840 (characterizing expert’s specific causation theory as “amount[ing] to
little more than speculation” because “evidence that halogen lamps can cause fires
generally . . . does not establish that the lamp in question caused this fire”). The
evidentiary record in this case provides no support for an assumption that a
manufacturing defect was the reason for the fire rather than some flaw introduced
after the product left Gharda’s control or some error committed by CSI, which had
control of the product after it accepted delivery.
I would affirm the district court’s take-nothing judgment. Because the
majority has concluded otherwise, I respectfully dissent.
