327 So.3d 658
Miss. Ct. App.2021Background
- Mother (Daphane Fonville) admitted for induced labor for severe preeclampsia; vacuum-assisted delivery performed after fatigue and slow labor, shoulder dystocia occurred, and newborn Derek suffered a permanent brachial plexus injury.
- Fonville sued Dr. Louay Zeid and Dr. Usha Mehta for alleged breach of the standard of care in delivery maneuvers; jury returned verdict for defendants; plaintiff appealed after post-trial motions denied.
- Defense originally disclosed experts in 2018; on Oct. 3, 2019 defendants supplemented opinions (relying on ACOG 2014 monograph) stating maternal (endogenous) forces of labor can cause transient or permanent brachial plexus injuries.
- Plaintiff moved to strike supplements and filed a Daubert motion to exclude maternal-forces theory; court held a Daubert hearing, allowed the theory, permitted supplemental depositions, but later struck limited portions (e.g., testimony about pounds of force and some specific causation testimony).
- At trial both sides’ experts discussed maternal forces; plaintiff’s own expert acknowledged the ACOG monograph and disagreed as to whether maternal forces alone could cause a permanent injury; jury found for defendants.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Supplemental expert opinions / "trial by ambush" | Defense supplemented after discovery deadline and ambushed Fonville with new causation opinions | Defense disclosed supplements, plaintiff deposed experts again, and court managed discovery remedy | No reversible error — plaintiff had notice, second depositions, and court struck some testimony; not ambush |
| Use of ACOG 2014 monograph (803(18) disclosure) | Defense failed to produce the full monograph; hearsay/Rule 803(18) violation | Monograph was disclosed in expert list; plaintiff had access/copy and the rule requires disclosure (not production) | No error — monograph was disclosed per Rule 803(18); plaintiff had it and no prejudice shown |
| Expert causation standard & maternal-forces admissibility (Daubert / probability v. possibility) | Defense expert gave "possible" causes and improperly advanced maternal forces theory lacking consensus/data | Defense relied on literature including ACOG 2014, and offered methodology and sources; admissibility is gatekeeper's discretion and conflicting expert opinions go to weight | No error — court properly applied Daubert factors, allowed maternal-forces testimony; experts stated opinions within a reasonable degree of medical probability; jury resolved the factual dispute |
| Impeachment with administrative discipline information | Defense sprung undisclosed administrative reprimands of plaintiff's OB expert, prejudicing credibility and violating discovery | Such disciplinary matters are admissible on cross-examination to attack credibility; not required to be produced for impeachment use | No error — court allowed limited impeachment (no underlying records given to jury); impeachment on credibility was proper and not unduly prejudicial |
