APPELLANT’S SUPPLEMENTAL AUTHORITIES

TO THE HONORABLE FOURTEENTH COURT OF APPEALS:

Appellant Wendy Schreiber submits these supplemental authorities, both

published within the past few days, in support of her appeal of the trial court’s

judgment.

If there were any doubt about the admissibility or discoverability of the facts

relating to Blevins’s and Deutsch’s bias, prejudice, and reputations for truthfulness,

the Texas Supreme Court has put that to rest:
 Relevance also governs the scope of cross-examination in Texas, as the
rules allow witnesses to be cross-examined “on any matter relevant to
any issue in the case.” Tex. R. Evid. 611(b). And it is well established
that “any fact which bears upon the credit of a witness would be a
relevant fact, ... whether it goes to his indisposition to tell the truth, his
want of opportunity to know the truth, his bias, interest, want of
memory, or other like fact.” Evansich v. Gulf, C. & Santa Fe R.R. Co.,
61 Tex. 24, 28 (1884).

JLG Trucking, LLC v. Garza, No. 13–0978, --- S.W.3d ----, 2015 WL 1870072 (Tex.

April 24, 2015) (emphasis added) (attached at Tab A). The trial court thus committed

error.

The ability to demonstrate bias, prejudice, and lack of truthfulness is especially

important in situations where, as here, the witness wears two hats:

Once he or she has qualified as an expert, and explained fire science to
the jury, the members of the jury are likely to perceive anything the
investigator says as scientific fact, even when that is not the case.
Particularly in a case where there is one individual serving as both the
scientist and the law enforcement investigator or case agent, there exists
a risk of confusion if the two roles are not distinguished.

A fire investigator’s core competency is determining where the fire
started. Recent studies have shown that the error rate for this important
task may be shockingly high. And knowledge that the homeowner was
behind his or her mortgage or recently had an argument with his or her
spouse are facts that are not the least bit relevant to the task.

JLG Trucking, LLC, Petitioner,
v.
Lauren R. Garza, Respondent
NO. 13–0978
Supreme Court of Texas.
Argued February 26, 2015
OPINION DELIVERED: April 24, 2015
ON PETITION FOR REVIEW FROM THE COURT OF APPEALS FOR THE FOURTH
DISTRICT OF TEXAS
JUSTICE LEHRMANN delivered the opinion of the Court.
*1 This case requires us to review the trial court's exclusion of evidence on relevance
grounds. The plaintiff was involved in two car accidents approximately three months apart.
After the second accident, she sued the opposing driver in the first accident and alleged that
this collision caused her injuries. The defendant sought to present two alternative defensive
theories. First, the defendant presented expert testimony that the plaintiff's injuries were de-
generative and thus not trauma-related at all. Alternatively, the defendant contended that the
second accident caused her injuries. On the plaintiff's pretrial request, and because of the lack
of expert testimony supporting the defendant's alternative theory, the trial court excluded all
evidence of the second accident on relevance grounds. The trial court rendered judgment on
the jury's verdict for the plaintiff, and the court of appeals affirmed. We hold that evidence of
the second accident was relevant to the central issue of whether the defendant's negligence
caused the plaintiff's damages. We further hold that the trial court committed harmful error in
excluding the evidence, and particularly in refusing to allow cross-examination of the
plaintiff's expert on the subject. Accordingly, we reverse the court of appeals' judgment and
remand the case for a new trial.
I. Background
On July 16, 2008, Lauren Garza was traveling south on U.S. Highway 83 in Zapata
County when an 18–wheeler driven by a JLG Trucking, LLC employee rear-ended her truck.
An ambulance was called to the scene but did not transport Garza to the hospital. Instead, Gar-
za testified that her aunt took her to a nearby emergency clinic where x-rays were taken, al-
though the record contains no medical records from the clinic regarding that visit. Five days
later Garza saw an orthopedic surgeon, Dr. Guillermo Pechero, complaining of neck and back
pain. An x-ray showed some straightening of the lordotic curve, which Dr. Pechero concluded

(Cite as: 2015 WL 1870072 (Tex.))

was associated with muscle spasms in the neck. Dr. Pechero prescribed physical therapy,
which Garza underwent for roughly eleven weeks.
On October 9, 2008, shortly after ceasing physical therapy, Garza was involved in a
second car accident. She was taken by ambulance from the scene of the accident to a hospital
on an immobilization board with a hard collar to prevent movement in her neck. At the hospit-
al, Garza complained of pain in her head, neck, and chest. On October 31, Garza returned to
Dr. Pechero for a follow-up visit, complaining of continuous pain in her neck that radiated in-
to her shoulders. Dr. Pechero ordered an MRI, which revealed that Garza had two herniated
discs in her neck. Dr. Pechero began a conservative treatment of primarily medication in
hopes of avoiding surgery, but a March 2009 nerve study revealed that a nerve at the site of
the herniations had become compressed, and a second MRI in August 2011 showed two addi-
tional herniated discs in her neck. Garza underwent spinal fusion surgery in January 2012. The
surgery was successful, and at the time of trial Garza was “doing well.” However, Garza lives
with a scar on her neck, reduced neck mobility, the permanent presence of hardware from the
surgery, and the possibility of future surgery.
*2 Garza sued JLG, alleging that the employee driver's negligence proximately caused her
injuries and seeking damages for past and future medical expenses, loss of earning capacity,
physical pain, mental anguish, physical impairment, and disfigurement.FN1 Garza's treating
physician, Dr. Pechero, served as her expert witness to testify that the July 2008 accident
caused the herniated discs. JLG designated Dr. Bruce Berberian, a neuroradiologist, as its ex-
pert witness to testify that Garza was suffering from degeneration of her discs, and not a
trauma-related injury at all. JLG also intended to introduce evidence of the October accident
as an alternative cause of Garza's injuries, although JLG did not designate an expert to testify
in support of that theory.
FN1. Garza named the employee as a defendant, but it appears that he was never
served with citation. Garza also asserted claims against JLG for negligent entrustment
and gross negligence, but those claims were not submitted to the jury.
Garza filed a pretrial motion to exclude any evidence of the second accident on the
grounds that such evidence was not relevant, or that its probative value was substantially out-
weighed by the unfair prejudice or confusion it would cause the jury, because “there is no
causal connection between the injuries [Garza] is complaining of and the subsequent colli-
sion.” After a hearing, the trial court granted Garza's motion to exclude.
Dr. Pechero testified by deposition at trial that the July accident caused Garza's injuries.
He noted that Garza exhibited neck pain after that accident and that the October MMI revealed
injuries consistent with a rear-end collision. One portion of the deposition played to the jury
contained the following exchange between Dr. Pechero and Garza's counsel:
Q. Now, up to this point in the treatment of her you took a history, correct?
A. Correct.
Q. And Lauren indicated to you that she had not had any or been involved in any other ac-

cidents other than the one from July—July 16th of 2008; is that correct?
A. I don't think I asked her one way or the other on that.
....
Q. Well, you took a history, correct?
A. Correct.
Q. All right. And let's take a look at the July 21st note real quick.
A. Okay. Are you referring to the October note, or the July note?
Q. The July note.
A. Oh, okay. In the July note, she did not have any other history of injury.
Taking the position that this testimony opened the door to questions concerning the second
accident, JLG renewed its objection to the exclusion of all mention or evidence of that acci-
dent. The trial court upheld its earlier exclusion ruling, and JLG submitted an offer of proof as
to the testimony that would have been elicited from Dr. Pechero and the evidence that would
have been presented in support of the second accident as an alternative cause. JLG's offer of
proof included the police report regarding the second accident, photos of Garza's vehicle after
the second accident, medical records documenting Garza's emergency treatment after that ac-
cident, and Dr. Pechero's testimony that he had not reviewed those medical records. Garza re-
sponded with an offer of proof consisting of Dr. Pechero's testimony that he had relied on Dr.
Berberian's testimony that the second accident did not cause Garza's injuries to rule out that
possibility. The jury found that JLG's employee's negligence proximately caused the July acci-
dent and awarded her $1,166,264.48 in damages. FN2
FN2. The jury awarded $108,135.48 for past medical expenses, $110,000.00 for future
medical expenses, $583,693.00 for future loss of earning capacity, $42,048.00 for past
physical pain, $252,288.00 for future physical pain, $5,000.00 for past physical
impairment, $57,600.00 for future physical impairment, and $7,500.00 for future dis-
figurement. The jury awarded $0 for past loss of earning capacity, past and future men-
tal anguish, and past disfigurement.
*3 JLG appealed the trial court's judgment on the verdict, arguing that evidence of the
second accident was relevant and that its exclusion amounted to harmful error because it pre-
vented JLG from holding Garza to her burden of proving that JLG caused her injuries. The
court of appeals affirmed, holding that the trial court did not abuse its discretion in excluding
evidence of the second accident because “expert testimony would be required to establish any
... causal link between the second collision and Garza's injuries.” ––– S.W.3d ––––,––––
(Tex.App.–San Antonio 2013).

Northborough P'ship v. State, 66 S.W.3d 213, 220 (Tex.2001). Erroneous exclusion of evid-
ence is reversible only if it probably resulted in an improper judgment. Id.; TEX. R. APP. P.P.
44.1(a)(1). In this case, the disputed evidence was excluded as irrelevant, and so the rules of
evidence governing relevance are the starting point of our analysis.
A. Evidence of the Second Accident Is Relevant to the Issue of Causation
Rule 401 broadly defines relevant evidence to include “evidence having any tendency to
make the existence of any fact that is of consequence to the determination of the action more
probable or less probable than it would be without the evidence.” TEX. R. EVID. 401. Evid-
ence that is not relevant is inadmissible, while relevant evidence is admissible unless other-
wise excluded by law. TEX. R. EVID. 402. Relevance also governs the scope of cross-
examination in Texas, as the rules allow witnesses to be cross-examined “on any matter relev-
ant to any issue in the case.” TEX. R. EVID. 611(b). And it is well established that “any fact
which bears upon the credit of a witness would be a relevant fact, ... whether it goes to his in-
disposition to tell the truth, his want of opportunity to know the truth, his bias, interest, want
of memory, or other like fact.” Evansich v. Gulf, C. & Santa Fe R.R. Co., 61 Tex. 24, 28
(1884). Finally, relevant evidence “may be excluded if its probative value is substantially out-
weighed by the danger of unfair prejudice, confusion of the issues, or misleading the jury.”
TEX. R. EVID. 403.
JLG argues that evidence of the second accident is relevant to the causation element of
Garza's negligence claim. We agree. Establishing causation in a personal injury case requires
a plaintiff to “prove that the conduct of the defendant caused an event and that this event
caused the plaintiff to suffer compensable injuries.” Burroughs Wellcome Co. v. Crye, 907
S.W.2d 497, 499 (Tex.1995). For example, when an accident victim seeks to recover medical
expenses, she must show both “what all the conditions were” that generated the expenses and
“that all the conditions were caused by the accident.” Guevara v. Ferrer, 247 S.W.3d 662, 669
(Tex.2007). Further, “expert testimony is necessary to establish causation as to medical condi-
tions outside the common knowledge and experience of jurors.” Id. at 665. Finally, we have
held that “if evidence presents ‘other plausible causes of the injury or condition that could be
negated, the [proponent of the testimony] must offer evidence excluding those causes with
reasonable certainty.’ ” Transcontinental Ins. Co. v. Crump, 330 S.W.3d 211, 218 (Tex.2010)
(quoting Merrell Dow Pharm., Inc. v. Havner, 953 S.W.2d 706, 720 (Tex.1997) (alteration in
Crump ) (emphasis in Crump omitted)); see also Harris v. Belue, 974 S.W.2d 386, 393–94
(Tex.App.–Tyler 1998, pet. denied) (rejecting the argument that the plaintiff failed to negate
other probable causes of her injury in light of the lack of factual support in the record for
those proposed causes).
*4 In this case, Garza sought to prove that the negligence of JLG's employee caused the
July accident. She also sought to prove by expert testimony from Dr. Pechero that this acci-
dent caused the herniated discs in her neck along with all of the associated pain, medical ex-
penses,FN3 loss of earning capacity, impairment, and disfigurement. JLG sought to under-
mine Garza's theory and Dr. Pechero's testimony by presenting evidence of the October 2008
accident as an alternative cause of those injuries. Garza argues that the record does not sup-
port a connection between the October accident and her injuries, rendering the evidence prop-
erly excluded.

(Cite as: 2015 WL 1870072 (Tex.))

FN3. Garza did not seek to recover medical expenses associated with her emergency
treatment immediately after the second accident.
Garza relies in part on Farmers Texas County Mutual Insurance Co. v. Pagan, 453 S.W.3d
454 (Tex.App.–Houston [14th Dist.] 2014, no pet.). In Pagan, the plaintiff alleged that vari-
ous neck and shoulder injuries were caused by a March 2008 car accident. Id. at 458. The de-
fendant sought to introduce evidence of an April 2009 “horse incident,” FN4 which the trial
court excluded. Id. at 459–60. The court of appeals affirmed, holding that the trial court
“could reasonably conclude that informing the jury about a horse incident with no apparent
connection to the lasting injuries at issue in this case would confuse the issues and mislead the
jury.” Id. at 463. The court noted in pertinent part that (1) the interrogatory response in which
Pagan identified the horse incident did not mention any resulting neck or shoulder injuries, (2)
the medical records associated with the incident noted only “contusions” resulting from the
fall, and x-rays showed that her spine and shoulders were normal, and (3) records from Pa-
gan's family doctor indicating that she complained of neck and shoulder pain at a visit after
the horse incident did not reference the incident itself. Id.
FN4. The evidence of the facts surrounding that incident is inconsistent. Some evid-
ence indicates that Pagan fell off a horse, other evidence indicates that she was
“trampled,” and still other evidence indicates that she fell while leading the horse on
foot. 453 S.W.3d at 459–60.
Regardless of whether Pagan was correctly decided, which we need not address, the evid-
ence of a connection between the proposed alternative cause and the plaintiff's injuries that the
court found lacking in Pagan is present in this case. JLG's offer of proof indicates that, as a
direct result of the second accident, Garza was transported to a hospital on an immobilization
board and constrained with a hard c-collar around her neck, she complained of neck pain once
she arrived, and she returned to Dr. Pechero three weeks later for the first time since the con-
clusion of her physical therapy with complaints of continuous pain in her neck radiating into
her shoulder. At that time, the MRI revealed the herniated discs. The circumstances surround-
ing the second accident and its aftermath provide the necessary factual support to present the
second accident as a “plausible cause” of Garza's injuries.FN5
FN5. Certainly, expert testimony in support of the alternative cause would lend support
to its plausibility. And in some cases, expert testimony may in fact be necessary to el-
evate a proposed alternative cause from theoretically possible to plausible. But this is
not that case.
Significantly, the exclusion of the second accident curtailed JLG's ability to probe Dr.
Pechero's conclusions about causation by asking him to explain why he discounted the second
accident as an alternative cause. JLG's offer of proof shows that, in formulating his opinion,
Dr. Pechero did not review the records from Garza's emergency treatment after the second ac-
cident, which included the statements reflecting that Garza was experiencing neck pain in its
wake. According to Garza's responsive offer of proof, Dr. Pechero's only explanation for rul-
ing out the second accident as the cause of the herniations was that he relied on Dr. Berberi-
an's testimony to that effect. But Dr. Berberian concluded that neither accident caused Garza's

injuries, calling into question the credibility of the methods underlying Dr. Pechero's ap-
proach. Cf. E.I. du Pont de Nemours & Co. v. Robinson, 923 S.W.2d 549, 559 (Tex.1995)
(upholding the exclusion of expert testimony when the expert failed to “carefully consider
[and rule out] alternative causes”);FN6 see also TEX. R. EVID.. 607 (“The credibility of a
witness may be attacked by any party....”). JLG could not adequately cross-examine Dr.
Pechero on those methods without discussing the improperly excluded evidence.
FN6. JLG did not move to exclude Dr. Pechero's testimony in the trial court. We cite
Robinson because it highlights the significance of alternative causes when a plaintiff
must prove causation by expert testimony.
B. The Court of Appeals Erroneously Conflated Relevance and Evidentiary Sufficiency
*5 The court of appeals held that the trial court correctly excluded evidence of the second
accident because “no expert testimony was proffered to establish that the second collision
caused any of Garza's injuries.” ––– S.W.3d at ––––. As support for its holding, the court of
appeals relied on a line of cases addressing the necessity of expert medical testimony to prove
causation in the personal-injury context. As discussed below, in doing so the court of appeals
conflated the concepts of relevance and evidentiary sufficiency and improperly shifted the
burden of proof to the defendant.
Principal among the cases cited by the court of appeals was Guevara v. Ferrer, 247
S.W.3d 662 (Tex.2007). That case, like this one, involved a car accident that a jury found the
defendant caused. Id. at 663, 665. The plaintiff, who had a complicated medical history that
included hypertension, heart disease, and kidney failure, complained of stomach pains and re-
ceived emergency treatment, including abdominal surgery, immediately after the accident. Id.
at 663–64. Following that surgery, he spent three-and-a-half months in the hospital, two
weeks in a continuing care facility, and two more weeks in another medical facility. Id. at 664.
His family sought to recover all the medical bills generated by his stays at the hospital and
both facilities, which exceeded $1 million, but did not present expert medical evidence to
prove that the accident caused those expenses to be incurred. Id. at 664–65. We held that,
while “the evidence [was] legally sufficient to support a finding that some of his medical ex-
penses [such as those associated with his post-accident treatment in the emergency room]
were causally related to the accident,” it was “not legally sufficient to prove what the condi-
tions were that generated all the medical expenses or that the accident caused all of the condi-
tions and the expenses for their treatment.” Id. at 669–70 (emphases added).
In Guevara, we applied the well-established general rule, cited above, that “expert testi-
mony is necessary to establish causation as to medical conditions outside the common know-
ledge and experience of jurors.” Id. at 665 (citing cases). And we did so in the context of con-
sidering the legal sufficiency of non-expert evidence to support a finding of causation. But we
did not hold that the lack of expert testimony rendered any of the evidence irrelevant or other-
wise admissible. In fact, relevance was not at issue in Guevara.FN7 In this case, although the
court of appeals was purporting to analyze relevance, in effect it was improperly analyzing
whether the evidence was legally sufficient to support a finding that the second accident
caused Garza's injuries. But JLG did not have the burden to prove causation; Garza did. It was
Garza's burden to prove that the first accident caused her injuries, and, as discussed above, the

 Page 7
--- S.W.3d ----, 2015 WL 1870072 (Tex.)
(Cite as: 2015 WL 1870072 (Tex.))

record in this case sufficiently demonstrates that the second accident is at least relevant to that
inquiry even without an expert proponent.
FN7. We did confirm in Guevara that “evidence of temporal proximity ... between an
event and subsequently manifested conditions” is not irrelevant to causation, although
“temporal proximity ... does not, by itself, support an inference of medical causation.”
247 S.W.3d at 667–68.
Further, JLG did not rule out the relevance of the second accident by presenting expert
testimony that Garza's injuries were degenerative and not trauma-induced. Parties may plead
conflicting claims and defenses in the alternative so long as they have a “reasonable basis in
fact [and] law.” Low v. Henry, 221 S.W.3d 609, 615 (Tex.2007). In turn, parties may present
evidence of alternative, and even inconsistent, theories of relief, leaving to the jury to “choose
the theory that it believes based upon its resolution of the conflicting evidence.” Wilson v.
Whetstone, No. 03–08–00738–CV, 2010 WL 1633087, at *10 (Tex.App.–Austin April 20,
2010, pet. denied) (mem.op.) (holding that the plaintiff's claim and evidence of the parties' ac-
quiescence to the alleged property boundary line were not fatal to her adverse possession
claim, even assuming that the claims were mutually exclusive); see also In re Arthur Ander-
sen LLP, 121 S.W.3d 471, 482 n.32 (Tex.App.–Houston [14th Dist.] 2003, orig. proceeding)
(noting that a defendant could deny liability for conspiracy while simultaneously alleging that
third parties were also liable for conspiracy). But the burden still falls on the plaintiff to estab-
lish the elements of her cause of action.
*6 In this case, as explained above, the burden was on Garza, the plaintiff, to establish
both that JLG caused the July 2008 accident and that this accident caused her injuries. Part of
that burden was to exclude with reasonable certainty other plausible causes of her injuries
supported by the record. Crump, 330 S.W.3d at 218. JLG's decision to present Dr. Berberian's
testimony in support of its theory that Garza's injuries were degenerative–which the jury ap-
parently found unpersuasive–did not relieve Garza of that burden. The defendant's responsibil-
ity “is not that of proving, but the purely negative one of repelling or making ineffective the
adversary's attempts to prove.” James B. Thayer, The Burden of Proof, 4 HARV. L. REV. 45,
56 (1890). In its efforts to repel Garza's attempts to prove her case, JLG was entitled to
present evidence of the second accident to the jury, which was relevant to Garza's theory of
causation irrespective of Dr. Berberian's testimony. The trial court therefore abused its discre-
tion in excluding that evidence.
C. Reversible Error
The trial court's error in excluding evidence of the second accident is reversible only if it
probably caused the rendition of an improper judgment. TEX. R. APP. P.. 44.1(a)(1). We have
declined to establish any “specific test” for determining whether evidentiary error resulted in
an improper judgment, but we have held that the appellate court must review the entire record,
“considering the state of the evidence, the strength and weakness of the case, and the verdict.”
Reliance Steel & Aluminum Co. v. Sevcik, 267 S.W.3d 867, 871 (Tex.2008) (internal quotation
marks and citation omitted). We explained in Sevcik that “if erroneously admitted or excluded
evidence was crucial to a key issue, the error was likely harmful.” Id. at 873. “By contrast, ad-
mission or exclusion is likely harmless if the evidence was cumulative, or if the rest of the

© 2015 Thomson Reuters. No Claim to Orig. US Gov. Works.
 Page 8
--- S.W.3d ----, 2015 WL 1870072 (Tex.)
(Cite as: 2015 WL 1870072 (Tex.))

evidence was so one-sided that the error likely made no difference.” Id. In this case, the evid-
ence of the second accident was crucial to whether JLG's negligence caused Garza's injuries,
and the harm in its exclusion was compounded by JLG's curtailed cross-examination of Dr.
Pechero. Accordingly, we hold that the trial court's exclusion of evidence regarding the
second accident was reversible error requiring a new trial.FN8
FN8. JLG did not contest on appeal the finding that its negligence caused the first acci-
dent. It asserted only that the erroneously excluded evidence tainted the findings as to
the damages caused by that accident. However, because liability was contested in the
trial court, both liability and damages must be remanded. Estrada v. Dillon, 44 S.W.3d
558, 562 (Tex.2001) (per curiam) (applying TEX. R. APP. P.P. 44.1(b)).
III. Conclusion
The trial court abused its discretion in excluding evidence of the second accident, which
was relevant to whether JLG's negligence caused Garza's damages. Accordingly, we reverse
the court of appeals' judgment and remand the case to the trial court for a new trial in accord-
ance with this opinion.
