255 So. 3d 1097
La. Ct. App.2018Background
- Riley Hickman, a lifelong smoker, developed large cell neuroendocrine carcinoma and sued oil companies and contractors alleging lung cancer and death from inhaling radioactive dust (NORM) while cleaning oilfield pipes across multiple years; he died during the lawsuit and his spouse/children continued the action.
- Shell moved for summary judgment asserting plaintiffs lacked medical causation proof that NORM (rather than smoking) was more likely than not the cause of Riley’s cancer.
- Plaintiffs relied principally on Dr. Patricia M. Williams, a toxicologist, who opined Riley’s radiation exposure increased his lung-cancer risk; Shell filed a motion to exclude/limit her testimony under La. C.E. art. 702/Daubert (art. 1425(F)).
- The district court granted summary judgment for Shell, reasoning that competent medical testimony tying the specific cancer to radiation (as opposed to smoking) was lacking and discounted Dr. Williams’ opinion.
- On appeal the court found the Daubert/art. 1425(F) challenge to Dr. Williams was never litigated (no hearing transcript or ruling) and therefore her opinion, unchallenged, must be accepted for summary-judgment purposes.
- The appellate court reversed and remanded, holding that the expert and treating physicians’ testimony created a genuine issue of material fact on causation and that the district court erred by weighing credibility and excluding expert evidence without an article 1425(F) hearing.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Medical causation burden at summary judgment | Williams’ toxicology opinion plus treating doctors create factual dispute that NORM could have caused or contributed to cancer | Plaintiff must prove by medical evidence that cancer was "more likely than not" caused by NORM; smoking likely the cause | Court: At summary judgment, plaintiffs need only raise a genuine factual dispute; Williams’ unchallenged opinion plus doctors’ testimony sufficed to create a triable issue |
| Expert admissibility / qualifications (art. 1425(F) / Daubert) | A toxicologist can offer competent medical-causation evidence; exclusion requires an article 1425(F) hearing | Williams lacks medical degree and unreliable methodology; her opinions should be excluded | Court: Because Shell never litigated an art. 1425(F) challenge, Williams’ opinion must be accepted for summary-judgment purposes; exclusion without hearing was error |
| Weighing expert credibility on summary judgment | Court should not weigh credibility or resolve conflicts when expert evidence is unchallenged | Court may assess sufficiency of expert proof and discount speculative opinions | Court: District court improperly weighed credibility and evaluated evidence rather than viewing evidence in light most favorable to non-movant |
| Jurisdiction/timeliness of appeal | Plaintiffs intended to appeal final judgment granting summary judgment; appeal timely under devolutive delay | Shell argued appeal referenced denial of new trial and was untimely | Court: Appeal maintained; inadvertent reference to wrong judgment does not defeat timely appeal from final judgment |
