TEXAS COURT OF APPEALS, THIRD DISTRICT, AT AUSTIN
NO. 03-06-00210-CV
Kenneth R. Jacob and Blair Jacob, Appellants
v.
International Cellulose Corporation, Inc., Appellee
FROM THE DISTRICT COURT OF TRAVIS COUNTY, 200TH JUDICIAL DISTRICT NO. D-1-GN-06-000904, HONORABLE JOSEPH H. HART, JUDGE PRESIDING
MEMORANDUM OPINION
In this property damage case arising from a house fire, appellants Kenneth R. Jacob
and Blair Jacob argue that the trial court erred in granting summary judgment for appellee
International Cellulose Corporation (ICC) and in excluding the affidavit of the Jacobs’ expert
witness. Because we conclude that the Jacobs failed to raise a genuine issue of material fact as to
each of their causes of action and that it was not an abuse of discretion to exclude their expert’s
affidavit, we affirm the trial court’s judgment.
FACTUAL AND PROCEDURAL BACKGROUND
The Jacobs’ home and all of its contents were destroyed by fire. At approximately
9:30 p.m. on November 29, 2002, the Jacobs discovered the fire in their attic and called the fire
department. The fire department arrived and, after extinguishing the fire, removed Sheetrock and
layers of smoldering insulation and used thermal imaging to detect remaining “hot spots.” Damage from the fire was concentrated in the attic, an office, hallway, and bathroom. In the early morning
hours of November 30, 2002, the fire reignited and the house was completely destroyed. The Travis
County fire investigator determined that the initial cause of the fire was electrical and that the
rekindling was due to the reignition of cellulose insulation in the attic.
Prior to the fires, the Jacobs had made home improvements. In December 1998, they
contracted with Alexander Builders to remodel their house, and the scope of the work included
electrical rewiring. Alexander Builders subcontracted the electrical work to Neal Wood Electric.
The remodel was completed in late 1999. In 2001, the Jacobs contracted with Enercheck Insulation,
Inc., to install insulation in their attic, and the product used by Enercheck for the project was
cellulose insulation1 manufactured by ICC. It is undisputed that Enercheck installed the ICC
cellulose insulation over an existing layer of cellulose insulation.
The Jacobs filed suit against Henry Miller, individually and d/b/a Alexander Builders;
Neal Wood, individually and d/b/a Neal Wood Electric; Enercheck; and ICC; however, only the
claims against ICC are currently before this Court, and we will limit our discussion accordingly.2
The Jacobs’ fourth amended original petition presented causes of action against ICC for product
liability, negligence, and breach of warranty. Specifically, they alleged defective manufacturing,
1 Cellulose insulation is made from recycled newspaper and treated with fire retardants and insect protection. 2 The trial court also granted summary judgment in favor of Neal Wood, individually and d/b/a Neal Wood Electric. The Jacobs separately appealed that ruling to this Court, and their appeals against Wood and ICC were consolidated. The appeal against Wood was dismissed, however, for lack of jurisdiction. See Jacob v. International Cellulose Corp., No. 03-06-00210-CV (Tex. App.—Austin Nov. 22, 2006) (order), available at http://www.3rdcoa.courts.state.tx.us/ opinions/HTMLOpinion.asp?OpinionID=15423.
2 defective design, negligent manufacturing, negligent design, negligent marketing and warning,
negligent testing and inspection, negligent installation and training, breach of express warranty,
breach of the implied warranty of merchantability, and breach of the implied warranty of fitness for
a particular purpose.
After extensive discovery, ICC filed two motions for summary judgment. In the first
motion, ICC asserted that (i) federal law preempted the Jacobs’ marketing and design defect claims;
(ii) ICC complied with federal regulations and was entitled under section 82.008 of the civil practice
and remedies code to a rebuttable presumption that it was not liable for any injury “caused by some
aspect of the formulation, labeling, or design” of its product, see Tex. Civ. Prac. & Rem. Code Ann.
§ 82.008(a) (West 2005); and (iii) the Jacobs had no evidence of causation, which is an element of
each of their alleged causes of action. In the second motion, ICC maintained that, because there was
no evidence as to certain required elements, or alternatively, because ICC had established as a matter
of law that the Jacobs could not prove certain required elements, ICC was entitled to summary
judgment on the Jacobs’ claims for manufacturing defect, negligent testing and inspection, negligent
training and installation, and breaches of express and implied warranties. The second motion also
asserted that use of res ipsa loquitur was not appropriate in this case. Both of ICC’s motions
included summary judgment evidence.
The Jacobs filed separate responses, including summary judgment evidence, to both
motions. Attached to both responses was the affidavit of one of the Jacobs’ experts, Robert Brady
Williamson. ICC objected to Williamson’s affidavit on the grounds that the affidavit addressed
issues about which Williamson was not designated to testify, did not address causation, and was
3 not competent expert testimony because it made conclusory allegations and was not credible or free
from contradictions.
The trial court sustained ICC’s objections to the Jacobs’ summary judgment evidence
and granted both of ICC’s motions for summary judgment. The court did not specify which ground
or grounds it relied upon in granting the motions. The claims against ICC were severed from the
claims against the other defendants, and this appeal followed.
ANALYSIS
On appeal, the Jacobs argue that the trial court erred in finding that their claims
against ICC were preempted by federal law and in granting summary judgment in favor of ICC as
to the Jacobs’ state law claims. They also contend that the trial court erred in excluding their
expert’s affidavit.
Standard of Review
We review summary judgments de novo. Valence Operating Co. v. Dorsett, 164
S.W.3d 656, 661 (Tex. 2005). ICC moved for summary judgment on both no-evidence and
rule 166a(c) summary judgment grounds; however, because we conclude that ICC satisfied the
burden for a no-evidence summary judgment, we discuss only that standard of review. A party
seeking a no-evidence summary judgment must assert that no evidence exists as to one or more of
the essential elements of the nonmovant’s claims on which it would have the burden of proof at trial.
Tex. R. Civ. P. 166a(i); Holmstrom v. Lee, 26 S.W.3d 526, 530 (Tex. App.—Austin 2000, no pet.).
Once the movant specifies the elements on which there is no evidence, the burden shifts to the
4 nonmovant to produce summary judgment evidence raising a genuine issue of material fact on
the challenged elements, and the court must grant the motion if the nonmovant fails to do so.
Tex. R. Civ. P. 166a(i). To defeat the motion for summary judgment, the nonmovant must present
more than a scintilla of probative evidence. Forbes Inc. v. Granada Biosciences, Inc., 124 S.W.3d
167, 172 (Tex. 2003). More than a scintilla of evidence exists if it would allow reasonable and
fair-minded people to differ in their conclusions. Id. Less than a scintilla of evidence exists when
the evidence is so weak as to do no more than create a mere surmise or suspicion of a fact. Id.
When a trial court’s order granting summary judgment does not specify the ground or grounds relied
on for its ruling, as here, summary judgment will be affirmed on appeal if any of the theories
advanced are meritorious. Carr v. Brasher, 776 S.W.2d 567, 569 (Tex. 1989).
We review the admissibility of expert testimony using the same standard on summary
judgment as at trial. United Blood Servs. v. Longoria, 938 S.W.2d 29, 30 (Tex. 1997). However,
as an appellate court, we do not consider the admissibility or inadmissibility of the evidence de novo.
Instead, a trial court has broad discretion in determining whether expert testimony is admissible, and
its ruling will be reversed only if that discretion is abused. Mack Trucks v. Tamez, 206 S.W.3d 572,
578 (Tex. 2006). A court abuses its discretion if it acts without reference to any guiding rules and
principles. Downer v. Aquamarine Operators, Inc., 701 S.W.2d 238, 241-42 (Tex. 1985). When
reviewing matters committed to the trial court’s discretion, a court of appeals may not substitute its
own judgment for that of the trial court. Walker v. Gutierrez, 111 S.W.3d 56, 63 (Tex. 2003).
5 Causation
The Jacobs brought causes of action against ICC in strict liability, negligence, and
breach of warranty, all of which require proof of causation. See Mack Trucks, 206 S.W.3d at 582.
The test for strict liability claims is producing cause, while negligence and breach of warranty claims
require a showing of proximate cause. Union Pump Co. v. Allbritton, 898 S.W.2d 773, 775
(Tex. 1995) (strict liability and negligence); Hyundai Motor Co. v. Rodriguez, 995 S.W.2d 661, 667
(Tex. 1999) (strict liability and breach of warranty); see also Tex. Civ. Prac. & Rem. Code Ann.
§ 82.005(a)(2) (West 2005) (requiring claimant in design defect case to prove by a preponderance
of evidence that defect was a producing cause). A producing cause is an efficient, exciting, or
contributing cause, which in a natural sequence of events, produces injuries or damages. Union
Pump Co., 898 S.W.2d at 775. Proximate cause consists of both cause in fact and foreseeability.
Id. Common to both proximate and producing cause is causation in fact, id., the test for which is
whether the negligent act or omission was a substantial factor in bringing about the harm and without
which the harm would not have occurred. Doe v. Boys Clubs of Greater Dallas, Inc., 907 S.W.2d
472, 477 (Tex. 1995). A finding of cause in fact may be based on either direct or circumstantial
evidence, but cannot be supported by mere conjecture, guess, or speculation. Marathon Corp. v.
Pitzner, 106 S.W.3d 724, 727 (Tex. 2003).
In its first motion for summary judgment, ICC asserted that, because there were two
layers of cellulose insulation installed in the Jacobs’ house, the Jacobs had no evidence that ICC’s
product—rather than the original layer of insulation—smoldered and caused the second fire. In
support of its motion, ICC attached the deposition testimony of the Jacobs’ experts and a Travis
6 County fire investigator. Each witness, with one exception, testified that he could not identify which
insulation caused the fire to reignite. Mack Fuller, a certified fire investigator, testified that
[k]nowing the fact that there’s two layers of cellul[ose] insulation, I have no way of telling you which one was which or where—you know, it certainly would stand to reason that the one that’s closer to the Sheetrock or to the lower level would probably have ignited before the one that was blown in above it.
In addition, Fuller stated that he could not rule out that wood rekindled the fire or that someone set
the fire. Andrew Armstrong, who had tested a product sample (although he did not know who
manufactured the sample), stated that he had no opinion as to the cause of either the first or second
fire. Lem Biggs, the Travis County fire investigator, testified that he was unaware there were two
kinds of cellulose insulation in the attic and that he did not know which one might have smoldered.
The Jacobs’ final expert, Robert Brady Williamson, did not distinguish between the two insulations;
instead, he testified during deposition that both insulations caused the second fire: “I think they both
smoldered, and I don’t think you could point the finger at either one of them as being the primary
one. They both smoldered.”
In response to ICC’s motion for summary judgment, the Jacobs proffered, as evidence
of causation, Williamson’s deposition testimony that both insulations caused the fire and a five-page
affidavit from Williamson.3 ICC objected to Williamson’s affidavit, arguing that it addressed issues
about which Williamson was not designated to testify, did not address causation, and was not
3 Also attached to the Jacobs’ response was Biggs’s incident report listing the cause of the second fire as rekindling of cellulose insulation and the deposition testimony of Gary Langshaw, an assistant fire chief who witnessed smoldering insulation after the first fire.
7 competent expert testimony because it made conclusory allegations and was not credible or free from
contradictions. The trial court sustained ICC’s objections and, thus, did not consider the affidavit
when granting ICC’s motions for summary judgment. On appeal, the Jacobs assert that the trial
court erred in excluding Williamson’s affidavit.
The only evidence presented by the Jacobs that would suggest that ICC’s product was
a cause of their house fire comes from Williamson. Thus, whether the Jacobs raised a material fact
issue as to causation turns on whether probative weight can be given to Williamson’s expert
testimony. A no-evidence summary judgment is proper if the only evidence offered by the
nonmovant to prove an essential element of the claim cannot be given weight by the court. Praytor
v. Ford Motor Co., 97 S.W.3d 237, 240 (Tex. App.—Houston [14th Dist.] 2002, no pet.). The
burden is on the proponent of expert testimony to show that the testimony is both relevant to the
issues in the case and based upon a reliable foundation. E.I. du Pont de Nemours & Co., Inc. v.
Robinson, 923 S.W.2d 549, 557 (Tex. 1995). To be relevant, the evidence must be “sufficiently tied
to the facts of the case that it will aid the jury in resolving a factual dispute,” and to be reliable, the
opinion must be based on principles or techniques that are “grounded ‘in the methods and procedures
of science.’” Id. at 556-57 (quoting Daubert v. Merrell Dow Pharms., Inc., 509 U.S. 579, 589
(1993)). To determine reliability, the supreme court has stated that a trial court should undertake a
“rigorous examination” of the facts on which the expert relies, the method by which the expert draws
an opinion from those facts, and how the expert applies the facts and methods to the case at hand.
Mack Trucks, 206 S.W.3d at 579.
8 In Robinson, the supreme court listed six nonexclusive factors a trial court
may consider in making the threshold determination of admissibility: (1) the extent to which
the theory has been or can be tested; (2) the extent to which the technique relies upon the subjective
interpretation of the expert; (3) whether the theory has been subjected to peer review and/or
publication; (4) the technique’s potential rate of error; (5) whether the underlying theory or technique
has been generally accepted as valid by the relevant scientific community; and (6) the non-judicial
uses that have been made of the theory or technique. 923 S.W.2d at 557. These factors may not
“fit” all types of expert testimony; however, that does not relieve the court of its responsibility to
evaluate reliability of the testimony. Gammill v. Jack Williams Chevrolet, Inc., 972 S.W.2d 713,
724 (Tex. 1998).
Conclusory statements made by an expert witness are insufficient summary judgment
evidence. Anderson v. Snider, 808 S.W.2d 54, 55 (Tex. 1991). It is the basis of the witness’s
opinion, and not the witness’s qualifications or his bare opinions alone, that can settle an issue as a
matter of law—“a claim will not stand or fall on the mere ipse dixit of a credentialed witness.”
Burrow v. Arce, 997 S.W.2d 229, 235 (Tex. 1999). The expert must explain the basis of his
statements to link his conclusions to the facts. Earle v. Ratliff, 998 S.W.2d 882, 890 (Tex. 1999).
There cannot be too great an “analytical gap” between the expert’s opinion and the facts upon which
he relies. Gammill, 972 S.W.2d at 726-27 (quoting General Elec. Co. v. Joiner, 522 U.S. 136, 146
(1997)). An expert who is trying to determine causation should carefully consider alternative causes;
the failure to rule out other causes of the damage renders the opinion little more than speculation.
Robinson, 923 S.W.2d at 559.
9 1. Williamson’s deposition testimony
In his deposition testimony, Williamson stated that both insulations caused the second
fire at the Jacobs’ house. During the deposition, ICC’s attorney questioned Williamson about how
the rekindling occurred and which insulation caused it:
Q. Why do you think that the underlying smoldering insulation wouldn’t have self-extinguished? . . .
A. We had the fire.
....
Q. So because it happened, it must not have. . . . Is that your opinion?
A. That’s correct.
Q. [L]et me give you a hypothesis. The old insulation smoldered and caused a second fire. Can you disprove that?
A. Yes. I just don’t think there is, they, all cellulose insulations smolder, and they have a propensity to smolder, and I don’t think you can distinguish between the two.
Q. In reality, Dr. Williamson, wouldn’t you agree, you have no idea which insulation particles smoldered and then ignited and caused the second fire . . . . Is there any possible way to tell?
A. They both could have smoldered.
Q. I’m asking you which one smoldered and caused the second fire in this case, specifically.
A. I don’t think we know.
10 ICC’s attorney also asked about what facts Williamson was relying on to support his opinion:
Q. What definite evidence are you relying on in stating that no other material could have caused the second fire? I’m—your definite evidence, if you could list it for me, I would appreciate it.
A. Well, what my opinion is is that the reasonable scientific certainty, the insulation caused it. I have identified other potential causes, like arson. I haven’t ruled that out today. I haven’t ruled out arson . . . . To a reasonable scientific certainty, I have, because I know the propensity of insulation.
Q. What evidence do you have or what facts are you relying on to support your opinion that the International Cellulose product, as opposed to the first layer of insulation, caused the second fire?
A. We don’t have any, there is no way to distinguish between the two.
Q. Okay. So if there is no way to distinguish between the two, then there is also no way to say that one, as opposed to the other, caused the second fire?
A. I’m not distinguishing between one as opposed to the other.
Q. Okay. So is it fair to say that we don’t know if the second fire was caused by the first layer or the second layer of insulation?
A. I think that both contributed.
Q. You think they could have, or they actually did?
A. I think they did. . . . I’m saying that those products both had the propensity to smolder. One doesn’t have a greater propensity. They both smolder, and they had surface contact over a large area. They are both going to smolder, and they caused the rekindling.
Q. Do you know if the smoldering insulation traveled through the International Cellulose product?
11 A. I think so.
Q. Okay. How do you know that?
A. The two are going to act the same.
Williamson’s statement that both insulations smoldered and caused the Jacobs’
second fire did not amount to more than mere speculation. Williamson stated that the insulation did
not self-extinguish, because “[w]e had the fire.” When asked specifically which layer smoldered and
caused the second fire, he stated, “I don’t think we know,” and when asked what evidence he was
relying on to determine that ICC’s product smoldered as opposed to the underlying layer of
insulation, he stated, “We don’t have any, there is no way to distinguish between the two. . . . I’m
not distinguishing between one as opposed to the other.” The basis for his opinion appears to be that
because the Jacobs’ attic contained cellulose insulation and because all cellulose insulation has a
propensity to smolder, the second fire must have been caused by both layers of cellulose insulation.
There is an analytical gap, however, between stating that cellulose insulation has a propensity to
smolder and concluding that ICC’s product actually smoldered and caused the fire. For instance,
even assuming both layers of insulation smoldered after the first fire, the record reveals that the fire
department removed large portions of smoldering insulation and could have removed all of the
smoldering ICC insulation. Thus, it appears equally plausible that the smoldering began solely in
the underlying layer of insulation and that without smoldering in that layer the fire would not have
reignited. We conclude that the “analytical gap” between the facts Williamson relied
upon—cellulose insulation’s presence in the Jacobs’ attic and its propensity to smolder—and his
opinion that both insulations caused the second fire is too great. See Gammill, 972 S.W.2d at 727.
12 In addition, Williamson’s opinion does not adequately address alternative causes of
the fire. He stated that he had considered other potential causes, specifically mentioning arson and
that arson could not be ruled out, but that he determined to a “reasonable scientific certainty” that
the insulation caused the fire. Williamson’s assurance that he had determined to a “reasonable
scientific certainty” that insulation caused the rekindling is not sufficient without some explanation
of the basis for his opinion. See Schaefer v. Texas Employers’ Ins. Ass’n, 612 S.W.2d 199, 205
(Tex. 1980) (“To ignore the substance of [the expert’s] testimony and accept his opinion as ‘some’
evidence simply because he used the magic words ‘reasonable probability’ effectively removes this
Court’s jurisdiction over any case requiring expert opinion testimony.”). Williamson did not name
any other potential causes, nor did he explain how he ruled out the other potential causes.
In this case, while circumstantial evidence may be sufficient to point to some cellulose
insulation as the cause of the second fire, that is not enough. Because there were two types of
cellulose insulation in the Jacobs’ house, there must also be some evidence that it is more likely than
not that the insulation manufactured by ICC was a cause of the fire. See Gaulding v. Celotex Corp.,
772 S.W.2d 66, 68 (Tex. 1989) (requiring plaintiff to prove which defendant supplied product
causing injury); see also City of Keller v. Wilson, 168 S.W.3d 802, 813 (Tex. 2005) (“In claims or
defenses supported only by meager circumstantial evidence, the evidence does not rise above a
scintilla . . . if jurors would have to guess whether a vital fact exists.”). Williamson does not point
to any evidence supporting his theory that both insulations caused the fire. When ICC’s attorney
asked Williamson how he can be sure that the smoldering did not take place solely in the underlying
layer of insulation, Williamson stated that the two layers were indistinguishable. While proving
13 causation may be difficult that does not excuse the plaintiff from introducing some evidence of
causation. Schaefer, 612 S.W.2d at 205. Williamson’s failure to rule out other causes of the fire
renders his opinion little more than speculation. See Robinson, 923 S.W.2d at 559.
Because there is too great an “analytical gap” between Williamson’s opinion and the
facts he relied upon and because Williamson failed to rule out other causes of the fire, we conclude
that the trial court did not err in finding that his deposition testimony did not constitute more than
a scintilla of probative evidence to raise a genuine issue of material fact as to causation.
2. Admissibility of Williamson’s affidavit
The trial court excluded the only other evidence the Jacobs submitted to show
causation, an affidavit from Williamson. We review the trial court’s exclusion of the affidavit for
an abuse of discretion. Mack Trucks, 206 S.W.3d at 578.
In his affidavit, which was filed after ICC filed its summary judgment motions,
Williamson does not discuss the theory he presented in his deposition testimony that both insulations
smoldered and caused the fire. Instead, after recounting his qualifications, Williamson avers that
ICC had a duty to warn installers that it is unsafe to allow old cellulose insulation to remain in
buildings, a duty to train installers in proper installation techniques, and a duty to instruct installers
to warn consumers that existing cellulose insulation should be removed before installing ICC’s
product. The affidavit then introduces a new theory of how the fire occurred—“[t]he installation of
new insulation over old, deteriorated and contaminated insulation created a hazardous condition in
the Jacobs’ attic” and the new cellulose insulation “prevented detection of the smoldering sub-layers
of insulation in the Jacobs’ attic after the first fire.”
14 One ground ICC relied upon in challenging Williamson’s affidavit was that it was
not competent expert testimony because it contained conclusory allegations and was not credible or
free from contradictions. See Anderson, 808 S.W.2d at 55. A review of Williamson’s affidavit
reveals that it suffers from the same problems as his deposition testimony. Williamson does not
provide any evidentiary support for his assertion that new cellulose insulation prevented detection
of smoldering sublayers of insulation nor does he rule out alternative causes of the fire. Especially
when viewed in light of his earlier deposition testimony that smoldering took place in both layers
of cellulose insulation, we cannot say that the trial court abused its discretion in excluding
Williamson’s affidavit.
CONCLUSION
We conclude that the Jacobs failed to produce evidence raising a genuine issue of
material fact showing that ICC’s insulation was a cause in fact of the fire that destroyed their house.
Because causation is a required element of each of the Jacobs’ claims, the trial court properly granted
summary judgment, and we affirm the judgment.
