EN BANC.

PIERCE, JUSTICE, FOR THE COURT:
2

¶1. In this personal-injury, products-liability case, the jury awarded the plaintiff $7

million, finding that Trellvion Gaines had been brain-damaged from exposure to lead. In an

effort to convince this Court to reverse the trial judgment and to render judgment in its favor,

the defendant, Sherwin-Williams Company, challenges the reliability of plaintiff’s causation

experts and fact witnesses. In the alternative, Sherwin-Williams alleges that unreliable,

unfairly prejudicial, and untimely disclosed expert testimony and a biased jury pool require

a new trial. 

STATEMENT OF THE CASE

¶2. Trellvion Gaines (“Trellvion”), the plaintiff, was born in 1991 and lived at all relevant

times in a wooden house on Highway 553 in Fayette, Mississippi, with his mother Sherneker

Pollard (“Pollard”), grandmother Doris Gaines (“Gaines”), and step-grandfather Johnny

“Cracker” Crawford (“Crawford”), who bought the house in late 1978 or 1979. The house

was built in the early 1900s and was burned in 1994. Expert testimony conclusively

established that samples of remains at the house site contained lead-based paint. Two blood

tests in September 1993 showed that Trellvion had elevated blood lead levels of 30

micrograms per deciliter (30 μg/dL) and 19 μg/dL five days later. Trellvion now has

significant cognitive deficiencies that he claims are a result of lead poisoning. 

¶3. Fact witnesses for Trellvion testified that they had bought and applied lead-based

paint manufactured by the Sherwin-Williams Company (“Sherwin-Williams”) to the interior

and exterior of the house at various times. Sherwin-Williams responded with testimony and

corporate documents to support its contention that it began to eliminate lead in its products

in the 1930s and stopped manufacturing any interior lead-based paint in 1954 and all

residential lead-based paint in 1972. This lawsuit was filed in 2000. Summary judgment was

granted for Sherwin-Williams by the Circuit Court of Jefferson County, affirmed by the

Court of Appeals, then reversed by this Court on writ of certiorari in 2007. The trial was 1

held in April 2009 in the Circuit Court of Jefferson County before the Honorable Lamar

Pickard, and a unanimous jury found for the plaintiff and awarded $7 million in

compensatory damages. Because this case has multiple, complex issues, relevant facts are

included in the discussion below.

DISCUSSION

I. Did the trial court err in denying Sherwin-Williams’ motion for

judgment notwithstanding the verdict?

¶4. Whether a party is entitled to a judgment as a matter of law is an issue that we review

de novo. Evidence should be considered in the light most favorable to the appellee, giving 2

that party the benefit of all favorable inferences which may reasonably be drawn from the

evidence. We will affirm the denial of a motion for directed verdict or a motion for 3

judgment notwithstanding the verdict if there is substantial evidence to support the verdict,

but we will reverse if the evidence, as applied to the elements of a party’s case, is either so

indisputable, or so deficient, that the necessity of a trier of fact has been obviated. Sherwin- 4

Williams offers three arguments on this issue, however the first argument is dispositive.
4

Did the plaintiff offer sufficient proof that his injuries were caused by SherwinWilliams lead-based paint?

¶5. The plaintiff concedes that no scientific study has causally connected permanent brain

damage to a single, asymptomatic elevation of blood lead to 30 μg/dL, followed by a rapid

decline to baseline. However, he argues, “It was not the opinion of [our] expert witnesses

that this case was a ‘single’ exposure. No matter how many times the Defendant says it was

a single exposure, does not make it true. Trellvion was exposed to toxic Sherwin-Williams’

lead paint dust for four (4) years.” We must determine whether the trial court erred in

determining that the core opinion – lead poisoning caused cognitive impairments – was

reliably based on science and the facts presented. 

¶6. Dr. John Rosen, one of two causation experts, testified by video deposition. He

opined that Trellvion was poisoned by lead from infancy through late 1993. He achieved this

opinion through “differential diagnosis.” He based his differential diagnosis on “the apparent

fact that [Trellvion] was excessively exposed to lead as a young infant.” He noted that

Trellvion’s only documented elevated blood levels were 30 μg/dL on September 15, 1993,

and 19 μg/dL on September 20, 1993.

¶7. “Exposure” to lead – or just being around it – is not dangerous. It must be ingested

to poison a person. Dr. Paul Mushak, accepted as an expert in the field of toxicology,

testified that blood lead levels of 10 μg/dL or higher are toxic. He further testified that

ingestion of fine lead dust is a major pathway for ingestion of lead. His opinion was that

Trellvion had been “exposed” to a “lead environment” from birth until the house burned, and

that lead paint was the source of Trellvion’s elevated blood levels in September 1993. 
Lidsky explained that “full scale” IQ is calculated by averaging scores on “verbal” 5

and “performance” tests. Trellvion’s verbal IQ score was 74, and his score on the

performance test was in the “high 60s.”

5

¶8. Dr. Theodore Lidsky, entered as an expert in the field of neuropsychology, performed

a differential diagnosis on Trellvion to determine that his brain had been injured by lead

poisoning, finding that, without the lead poisoning, Trellvion’s IQ would have been in the

“in the bottom of the low average range.” Lidsky explained that, while “lead is eliminated

relatively rapidly from the blood . . . even when it’s gone from the blood, it’s still in the

brain.” To determine whether Trellvion had a brain injury, Lidsky used a method called

“deficit measurement . . .which is where you look at a person’s baseline level of functioning

and look to see if there are scores that deviate . . . from that baseline.” The baseline is the

level at which one would expect that person to function, but for brain injury. Lidsky testified

that “as a matter of course” professionals add points to the patient’s known IQ score to

determine the baseline in “lead poisoning” cases because “we know his IQ goes down. It’s

one of the most established points in science . . . . So you have to add a number of points.”

Lidsky added ten points to Trellvion’s full-scale IQ (or six to his higher score, a 74 verbal

IQ). 

5

¶9. Lidsky explained this “baseline” method further:

When I tested [Trellvion] in 2001, his IQ was about almost 69 . . . . You look

at that as his baseline and then you look at his testing. If there’s an impairment

at that point, without adjusting his baseline, then you adjust the baseline. If

there’s no impairment at that point, then you say, this is what he is, and you

can’t adjust it . . . . Before [I] even looked at his baseline [I] know he’s injured.

At that point, he starts at the baseline. Before, like you said, you are assuming

the child is injured just by looking at his lead level. You can’t do that.
The cause of as many as one half of cases of mental retardation is unknown or 6

“idiopathic.” D.K. Daily, H.H. Ardinger, G.E. Holmes, Identification and Evaluation of

Mental Retardation, 61 (4) Am. Family Physician 1059–67, 1070 (Feb. 2000).

6

Lidsky agreed that the neuropsychological tests that he uses are not designed to detect the

cause of any particular deficit. He testified, nevertheless, that he still could conclude that

Trellvion’s injury was caused by lead. Lidsky testified that no studies had been done linking

“acute exposures” to lead with IQ reduction because “based on what the CDC has stated,

there are no acute exposures.”

¶10. Lead poisoning was, in the opinion of Dr. Rosen, the cause of permanent intellectual

impairments uncovered by Dr. Lidsky. When asked if he would have diagnosed Trellvion

with lead poisoning in the absence of the two elevated blood lead results, Dr. Rosen

responded,

I would have recognized – I would have diagnosed him as having the disease

of – of excessive lead exposure, and that disease is a pervasive disease that

involves every organ of a child’s body including their brain, and that is one

aspect or one compartment so to speak of ultimately the fact that he was

exposed to enough lead in the initial phase of child – of excessive exposure to

lead to elevated blood leads.

Finally, when asked how he was able to rule out an idiopathic cause for Trellvion’s mental

retardation, Dr. Rosen replied, “I ruled it out because there is nothing in the medical records 6

to indicate that there is any – any so called etiopathic [sic] or unknown cause. What is

unknown is unknown . . . .”

¶11. The plaintiff’s experts seemingly contradict each other and themselves. For example,

Dr. Lidsky testified that adding points to determine a baseline IQ is a “matter of course” in

“lead poisoning” cases because “we know his IQ goes down . . . [i]t’s one of the most
Miss. Transp. Comm’n v. McLemore, 863 So. 2d 31, 40 (Miss. 2003). 7

7

established points in science.” However, Dr. Mushak, plaintiff’s expert toxicologist, testified

that “no one has done the data, gathered the data to show” whether “any time a child has an

elevated blood lead level, it’s going to result in the loss of IQ points.” And Dr. Lidsky at one

point testified that finding the injury depends on calculating the baseline (including adding

points assumed by lead poisoning), but later asserted that it is improper to assume that a child

is injured based solely on an increased blood lead level. Further, it is difficult to determine

whether Lidsky’s opinion in the case is, proverbially, a chicken or an egg. Dr. Rosen

assumed, in reliance upon Dr. Lidsky’s findings, that Trellvion was, in fact, injured (and not

just “slow”) to differentially diagnose exposure to lead as the cause of the injury. However,

Lidsky’s admitted method, “deficit measurement,” depended upon the calculation of a

baseline, which depended upon assuming that Trellvion had been poisoned by lead. Dr.

Lidsky was, essentially, leaning on Dr. Rosen’s theory of causation, who was leaning on Dr.

Lidsky’s theory of injury, who was leaning on Dr. Rosen’s theory of causation . . . ad

infinitum. Finally, while Dr. Rosen testified that he could have diagnosed Trellvion with the

disease of “excessive lead exposure” even without a documented elevated blood level, he

subsequently testified that lead poisoning cannot be diagnosed without a blood lead test.

¶12. The plaintiff characterizes Drs. Rosen and Lidsky as “some of the world’s leading

experts in their respective fields[.]” Sherwin-Williams responds that the trial court failed to

exercise its “gatekeeping duty” because it allegedly did not “undertake any meaningful 7

evaluation [of the reliability of the opinions] beyond expert credentials.”

“After this, therefore, because of this.” 14

8

¶13. Mississippi Rule of Evidence 702 and our familiar Daubert standard require trial 8

courts to act as “gatekeepers” with regard to expert opinion testimony, because juries tend 9

to place great weight on the testimony of experts and can be misled by unreliable opinions.10

But we are mindful that the exclusion or admission of expert testimony is within the

discretion of the trial court, and, furthermore, vigorous cross-examination, presentation of 11

contrary evidence, and careful instruction on the burden of proof are traditional and

appropriate means of attacking shaky but admissible evidence.

12

¶14. The opinions expressed by Drs. Rosen and Lidsky, however, were not reliable. A

dose-response ratio is critical to determining the causal connection between a poison and an

injury. In this case, the only known dose – or ingestion of lead – is represented by 13

Trellvion’s elevated blood lead levels from September 1993. The experts extrapolated both

dose and duration with only circumstantial supporting evidence, engaging in a classic logical

fallacy: post hoc ergo propter hoc. Dr. Lidsky explained: “[H]e was raised in the house, 14

the same house from the day of birth. What’s the likelihood that [Dr. Timm] just happened
Hill v. Mills, 26 So. 3d 322, 329 (Miss. 2010) (Expert testimony must proceed from 15

“what is known, and the expert must have knowledge that is more than subjective or

unsupported speculation.”). 

See Smith ex rel. Smith v. Clement, 983 So. 2d 285, 289 (Miss. 2008). 16

9

to [test Trellvion’s blood] on the day that his blood level was 30?” This opinion was not

based on some epidemiological study calculating the likelihood of elevated blood levels

based on the levels of paint in the home. Neither was it based on Trellvion’s medical

records. The basis for Lidsky’s and Rosen’s causation testimony – that Trellvion was

ingesting and being poisoned by lead the entire time he lived in the house – was mere

speculation and inadmissible.15

¶15. We are urged by amici to instruct trial court judges that consideration of the

“relevance and reliability” of an expert’s opinion (and not simply the expert’s qualifications)

is a necessary part of the trial court’s duty as a gatekeeper. The trial judge in this case did

not consider many of Sherwin-Williams’s arguments concerning the reliability of plaintiff’s

experts, regarding them as challenges to the weight and not the admissibility of the experts’

testimony. Amici urge that we instruct trial courts to make particularized findings as to the

admissibility of expert opinions, when those challenges are raised before trial. In this case,

a Daubert challenge was filed before trial, and the court chose to delay ruling until trial, by

which point the court did not have time to read the briefs and fully consider the arguments.

Our trial judges work exceedingly hard and have discretion in how they discharge their

gatekeeping duty, but we take this opportunity to reiterate that such duty includes making 16

10

sure that the opinions themselves are based on sufficient facts or data and are the product of

reliable principles and methods.17

¶16. Because Drs. Lidsky’s and Rosen’s speculation that Trellvion had been ingesting lead

throughout his entire residence at the home was unreliable and, therefore, inadmissible, and

because the plaintiff’s experts did not present any scientific authority that an acute,

asymptomatic ingestion of lead could lead to the alleged injuries, the plaintiff did not offer

sufficient proof of causation. That admission of the speculation of Drs. Lidksy and Rosen

would, alone, trigger a new trial. However, because of the lack of sufficient proof of

causation, we find that the court should have granted Sherwin-Williams’ motion for

judgment notwithstanding the verdict.

¶17. The separate opinion opines that the fact-witness testimony presented by the plaintiffs

is insufficient to create an issue for the jury. While the testimony of these fact witnesses is,

in various ways and to varying degrees, incredible, self-contradictory, and circumstantial, this

Court has held that even contradictory evidence and evidence that has been impeached

creates an issue for the jury.18

¶18. In Rucker v. Hopkins, we said that incredible testimony and the testimony of a

plaintiff which is so clearly and manifestly improbable should be disregarded; this also

applies to testimony that has been clearly impeached. In Elsworth v. Glindmeyer, we 19

reversed and remanded a jury verdict for a defendant in a wrongful death suit because “[n]o

11

court is required to believe, or should be bound by improbable, incredulous, or unreasonable

evidence . . . which is violative of physical laws, human experience and common sense, and

which intrudes into the realm of the supernatural.” However, subsequently, in Doe v. 20

Stegall, we found error where a trial judge, relying on Rucker, excluded the testimony of a

fact witness who had been “clearly impeached.” The logical extension of Stegall is that 21

fact testimony, no matter how thoroughly contradicted or impeached, may create an issue for

the jury, so long as it is not supernatural. Indeed, in Rucker, we said, “[e]ven where the

evidence is such that a judgment for the adverse party would have to be set aside as being

contrary to the overwhelming weight of the evidence, it does not necessarily follow that a

party is entitled to a directed verdict. The trial court did not err in denying the motions for 22

directed verdict and judgment notwithstanding the verdict based on this argument, because

the fact-witness testimony created an issue for the jury.

CONCLUSION

¶19. Because Drs. Lidsky’s and Rosen’s speculation was inadmissible, and because the

plaintiff’s experts did not present any scientific authority that an acute, asymptomatic

ingestion of lead could lead to the alleged injuries, the plaintiff did not offer sufficient proof

of causation. Accordingly, we reverse and render on this issue, and not on whether the factwitness testimony sufficiently established product identity.

KITCHENS, JUSTICE, CONCURRING IN RESULT ONLY:

¶21. To prevail on a product liability claim, the plaintiff must provide sufficient evidence

of product identification, exposure, and proximate cause. Monsanto Co. v. Hall, 912 So. 2d

134, 136 (Miss. 2005) (citing Miss. Code Ann. § 11-1-63 (Rev. 2002)). The plurality

opinion reverses the verdict for the plaintiff and renders judgment in favor of the defendant,

finding the evidence of exposure and proximate cause to have been speculative and

unreliable. Respectfully, I cannot join that analysis. While I agree that a judgment in favor

of the defendant is warranted, it is because of the failure of the plaintiff’s proof of product

identification. 

¶22. Sherwin-Williams presented substantial evidence that it had stopped manufacturing

residential lead-based paint in 1972, but the plaintiff produced three witnesses who testified

that lead-based Sherwin-Williams paint was used in the house between 1978 and 1994. 

¶23. Doris Gaines, the plaintiff’s grandmother, testified that she had painted the home

several times between 1979 and 1994, and that she always had asked the store for SherwinWilliams “lead” paint. The grandmother acknowledged that she never had read the paint

labels, but merely assumed that the paint contained lead because she had asked for lead paint.

¶24. Vernon Collier was a long-time friend of the grandmother’s who would help her with

various construction and painting projects in her house. Collier testified that he had helped

Ms. Gaines paint the outside of the house in 1979 with Sherwin-Williams paint. Collier
13

stated that he believed the paint contained lead because it covered the painted surface in one

coat, but he did not read the labels. Moreover, in an earlier deposition, Collier stated that he

and Doris did not use Sherwin-Williams paint in the latter part of the 1970s because “[Doris]

wasn’t into Sherwin-Williams at that time.”

¶25. Johnny Crawford, the plaintiff’s step-grandfather, purchased the house in 1978.

Crawford testified that he had bought and used Sherwin-Williams lead paint in the late 1970s

and recalled seeing the words “lead paint” on the labels. This testimony was directly

contradicted by a prior affidavit wherein he swore that he had no knowledge whether the

paint used on the house contained lead or what brand of paint was used.

¶26. The plaintiffs produced one witness who testified about the paint used on the house

before 1978. Reverend Martin Lias’s deposition was read to the jury, and he testified that

he had witnessed the painting of the back porch with white Sherwin-Williams lead paint in

the 1930s. However, the grandmother, Ms. Gaines, testified that the back porch had been

removed before the plaintiff was born, rendering Reverend Lias’s testimony irrelevant in the

present case.

¶27. Thus, the testimony by the plaintiff’s witnesses was insufficient to support a verdict

against the Sherwin-Williams Company. Collier’s and Crawford’s testimony was directly

and materially contradicted by their prior sworn statements; thus, that testimony was

substantially impeached. Jakup v. Lewis Grocer Co., 200 So. 597, 599 (Miss. 1941). Ms.

Gaines merely assumed that the paint contained lead because she had requested lead paint,

but “[i]t is well settled in this jurisdiction that a verdict may not be based upon surmise or

conjecture and that to prove a possibility only is insufficient to make a jury issue.” John
The plurality holds that “fact testimony, no matter how thoroughly contradicted or 23

impeached, creates an issue for the jury, so long as it is not supernatural,” relying on Doe v.

Stegall, 757 So. 2d 201, 205 (Miss. 2000). Plur. Op. ¶ 18. However, Stegall involved

excluding fact witnesses at the summary judgment stage. Id. (“While it is true that this Court

has held that there are instances in which judges are allowed to disregard or instruct against

incredible and unreliable testimony at trial, this Court has never held similarly at the

summary judgment stage in a proceeding.”)

14

Morrell & Co. v. Shultz, 208 So. 2d 906, 907 (Miss. 1968). Therefore, the verdict cannot 23

stand, and I respectfully concur in result only.
