120 N.E.3d 244
Ind. Ct. App.2019Background
- On December 8, 2016, David Martin was rear-ended by Jose Ramos; Ramos conceded fault and the trial court found him 100% liable.
- Martin sought small-claims damages for head, neck, chest, back, and shoulder injuries; he had preexisting neck/back conditions.
- Martin sought emergency and follow-up care; a CT from the incident showed a left front post‑traumatic subarachnoid hemorrhage and degenerative cervical changes.
- Trial was held in the Allen Superior Court Small Claims Division (bench trial); the trial court found causation unproven and denied damages.
- The trial court relied on precedent requiring expert medical testimony for causation of subjective/aggravated preexisting injuries; Martin moved to correct error and appealed after denial.
- The Court of Appeals reversed, holding the trial court erred as a matter of law in concluding Martin failed to prove causation as a matter of law and remanded for determination of damages.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Whether expert medical testimony is required in small claims for causation of subjective injuries | Expert testimony is not required in small claims; informality and access justify allowing lay proof and medical records to establish causation | Trial court argued Topp/Daub require expert testimony when causation is not within lay understanding | Expert testimony not always required; small claims informality does not lower substantive burdens, but lay proof can suffice where causation is within lay understanding |
| Whether Martin established causation between collision and his injuries | Martin: contemporaneous complaints, medical treatment, CT showing post‑traumatic subarachnoid hemorrhage, and temporal congruity suffice to prove causation without expert opinion | Ramos: preexisting conditions and subjective nature of symptoms require expert testimony to apportion causation | Court held Martin presented sufficient circumstantial and objective evidence (CT finding, contemporaneous treatment, testimony) that a lay factfinder could infer causation; reversal and remand for damages |
Key Cases Cited
- Daub v. Daub, 629 N.E.2d 873 (Ind. Ct. App. 1994) (expert testimony required when causal link between injury and preexisting conditions is a complicated medical question)
- Topp v. Leffers, 838 N.E.2d 1027 (Ind. Ct. App. 2005) (followed Daub in holding expert necessary where injuries are subjective and causation is medically complex)
- Smith v. Beaty, 639 N.E.2d 1029 (Ind. Ct. App. 1994) (causation may be proved by circumstantial evidence when evidence permits a legal inference rather than mere speculation)
- Barrow v. Talbott, 417 N.E.2d 917 (Ind. Ct. App. 1981) (noting that causation need not always be proven by expert testimony)
