794 F.3d 697
7th Cir.2015Background
- District court disqualified Higgins’s causation expert Dr. Margherita for unreliable methodology.
- Koch moved for summary judgment arguing Higgins could not prove causation without an expert.
- Higgins contended no expert was needed or his treating physician could serve as causation expert.
- Higgins alleged exposure at Holiday World caused RADS and asthma; Dr. Haacke diagnosed these conditions more than a year later.
- The district court ruled Higgins failed to establish causation without an expert and granted summary judgment; Higgins appealed.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Whether expert testimony is required to prove specific causation | Higgins: laypeople can determine causation for chlorine exposure | Koch: specialized medical causation evidence is needed | A causation expert is required |
| Whether Dr. Haacke can serve as causation expert without Rule 26 disclosure | Treating physician should be allowed as causation expert | Rule 26 disclosure requirements apply; Haacke lacks proper disclosure | Rule 26 disclosure and expert reliability issues prevent Haacke from baring as causation expert |
| Whether Haacke’s testimony satisfied Daubert reliability | Haacke relies on treating experience and patient history | Haacke’s methodology and data are unreliable | Haacke’s causation opinion not reliable under Daubert |
| Whether Indiana law permits medical causation questions to be proven without an expert | Some lay understanding suffices for chlorine injury | Medical causation requires expert physician testimony | Indiana law requires an expert for specific causation in complex chemical exposure cases |
| Whether the district court properly excluded the treating physician as qualified causation expert | Haacke is qualified as a pulmonologist and should be allowed | Haacke lacked proper qualification/methodology for causation | District court did not abuse discretion in excluding Haacke as causation expert |
