Facts

Plaintiff offered four experts on tobacco-related topics, economic damages, punitive-damages financial condition, and causation. Dr. Yerger proposed to testify based on tobacco document archive research; Johnson offered opinions on plaintiff's economic damages and defendants' financial condition; Dr. Smith, an epidemiologist, proposed to testify that smoking caused plaintiff's lung cancer; and Dr. Cummings, also an epidemiologist focused on public health, proposed opinions on advertising, addiction, consumer risk perception, and tobacco company knowledge. Defendants challenged the experts' qualifications, methodologies, and the timeliness of certain supplemental reports. The court evaluated each opinion for qualification, reliability, and relevance under Rule 702.

Issue

Whether the proffered opinions of plaintiff's four experts were admissible under Federal Rule of Evidence 702 and Daubert. More specifically, the court had to decide whether each expert was qualified, whether the opinions were based on reliable methods, whether they fit the issues in the case, and whether untimely supplemental opinions should be excluded.

Rule

Under Federal Rule of Evidence 702, the proponent must show by a preponderance of the evidence that expert testimony will help the trier of fact, is based on sufficient facts or data, is the product of reliable principles and methods, and has been reliably applied to the facts. Daubert requires the court to act as gatekeeper and conduct a two-part inquiry into reliability and relevance or fit; reliability focuses on methodology rather than conclusions, and testimony may be excluded where there is an analytical gap, failure to explain methodology, inadequate consideration of alternatives, or only ipse dixit support. Expert testimony interpreting documents that speak for themselves or opining beyond the witness's expertise is not admissible, and untimely supplemental expert opinions may be excluded.

Test yourself

One of 10 multiple-choice questions for this case. Pick an answer to see why.
In a products-liability suit in Denver, Maya Torres offers Professor Lena Voss as an expert. Voss has spent years searching a public archive of internal chemical-company records and says her specialty is "industrial archive interpretation," but she has no training in toxicology, pharmacology, or chemistry.

Voss proposes to testify that the solvent at issue causes neurological dependence and liver damage because company documents discuss those topics. Which is the best ruling?

Explanation. Under Rule 702 as applied here, the proponent must show qualification, reliability, and fit. The majority held that expertise in searching or reviewing archives does not itself qualify a witness to opine on the scientific subject matter contained in the documents. It also held that testimony merely interpreting documents that speak for themselves does not assist the jury. (Derived from Pooshs v. Phillip Morris U.S.A. (n.d.).)
