Summary
The Supreme Court of Texas held that the plaintiffs' expert testimony was legally insufficient to establish that a Wal-Mart lamp caused a fatal house fire. The court reversed the court of appeals and rendered judgment that the plaintiffs take nothing, concluding that the expert's causation theory was speculative and failed to adequately address alternative causes.

Questions Presented
- Whether the plaintiffs' expert testimony supplied legally sufficient evidence that the lamp was defective and caused the fire.
- Whether an expert's opinion is legally insufficient when it fails to explain or adequately disprove obvious alternative causes of the event.
Holdings
- Dr. Beyler's testimony was legally insufficient to establish that the lamp caused the fire because his opinion was speculative and conclusory and lacked objective, evidence-based support.
- Because the expert testimony was legally insufficient to support causation, the plaintiffs could not prevail on their claims, and judgment was rendered that they take nothing.
Key quotations
“An expert's failure to explain or adequately disprove alternative theories of causation makes his or her own theory speculative and conclusory.” (840)
“Evidence that halogen lamps can cause fires generally (assuming that the lamp here was a halogen lamp) does not establish that the lamp in question caused this fire.” (840)
Factual background
Charles Merrell, Jr., and Latosha Gibson died from smoke inhalation in a rented home where a badly burned recliner, a pole-style floor lamp, candles, smoking paraphernalia, and marijuana cigarette butts were found. The fire marshal determined that the fire was accidental and of unknown origin, and the property owner discarded the burned household items after the investigation. The plaintiffs' expert, Dr. Craig Beyler, attributed the fire to a nonpassive failure of a halogen lamp that ignited the recliner, while Wal-Mart's expert attributed it more likely to careless disposal of smoking materials.
Procedural history
The trial court admitted the plaintiffs' expert testimony over Wal-Mart's objection but granted Wal-Mart's no-evidence motion for summary judgment. The court of appeals reversed, holding that the plaintiffs produced evidence on each challenged element. The Supreme Court of Texas reversed the court of appeals and rendered judgment that the plaintiffs take nothing.
