190 So. 3d 1135
Fla. Dist. Ct. App.2016Background
- Collision where Andrew Maines ran a red light and struck Marcia Fox; appellants admitted negligence but disputed that the crash caused Fox’s cervical disc injury and need for surgery.
- Jury found Fox suffered a permanent injury and awarded $143,896.32; Fox moved for attorney’s fees under Fla. Stat. § 768.79 based on settlement proposals she served in October 2013.
- Appellee presented treating providers (chiropractor and surgeon) who testified the accident caused the disc herniation; surgeon (Dr. Poelstra) testified both as surgeon and with biomedical engineering background about force thresholds.
- Defendants presented Dr. Keller (orthopedist) and Dr. Bowles (biomechanical engineer and surgeon). Dr. Bowles performed a force/G-force analysis and concluded forces were too low to cause Fox’s specific injury.
- Trial court excluded Dr. Bowles’ specific-causation opinion under Daubert as an improper “bridge” from biomechanical analysis to medical causation, but permitted his force calculations and general-causation testimony; jury nonetheless returned verdict for plaintiff.
- Appellants challenged: (1) admission of testimony about why Andrew ran the light; (2) exclusion/limiting of Dr. Bowles’ specific-causation testimony; and (3) award of attorney’s fees based on allegedly ambiguous settlement proposals.
Issues
| Issue | Plaintiff's Argument (Fox) | Defendant's Argument (Maines) | Held |
|---|---|---|---|
| Admissibility of testimony why Andrew ran the red light (relevance) | Testimony about why Andrew ran the light was relevant to speed and causation of injury | Exclude as prejudicial/irrelevant to injury causation | Affirmed admission: testimony relevant to speed and causation |
| Exclusion of Dr. Bowles’ specific-causation opinion under Daubert | Dr. Bowles’ force analysis is not a reliable medical basis to opine on specific causation; medical causation requires traditional medical methods | Dr. Bowles could rely on his unchallenged biomechanical force analysis in conjunction with medical training to offer specific-causation opinion | Trial court abused discretion in excluding the specific-causation opinion, but error was harmless because allowed testimony conveyed substantially the same views to the jury |
| Scope of permissible biomechanical testimony (general vs. specific causation) | Biomechanical experts should be limited to general-mechanism testimony, not medical diagnosis/causation | Hybrid expert (biomechanical engineer + MD) may combine force analysis with medical judgment to address specific causation | Biomechanical calculations are admissible for general causation; medical experts may give specific causation; hybrid experts can bridge if methodology reliable — exclusion here was erroneous but harmless |
| Attorney’s fees based on settlement proposals (Rule 1.442 / §768.79) | Proposals were valid and triggered fee-shifting because defendants rejected them | Proposals were ambiguous regarding whether they included attorneys’ fees and costs, so they should not support fee award | Vacated fee award: proposals were internally inconsistent and ambiguous about fees/costs, failing strict particularity required by rule/statute |
