Jackson v. Ghayoumi
419 S.W.3d 40
Ky. Ct. App.2012Background
- Jacksons sued chiropractor Mehdi Ghayoumi for medical malpractice in 2007 over electrical-stimulation treatment to Melissa Jackson’s neck.
- Jacksons alleged the treatment caused Melissa’s miscarriage at six weeks.
- Jacksons disclosed Dr. David M. Priver as an expert on causation, but he admitted no knowledge of electrical stimulation transmission or how it could cause miscarriage.
- Trial court conducted a Daubert-type hearing and excluded Priver’s testimony as unreliable and speculative.
- Previous order (Nov. 29, 2010) barred disclosure of additional expert witnesses.
- Trial court granted summary judgment for Ghayoumi on July 20, 2011; Jacksons appealed, challenging both the exclusion and the judgment.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Was the exclusion of Priver’s testimony an abuse of discretion? | Jacksons contend exclusion was improper given expertise. | Ghayoumi argues Priver lacked reliability and relevant knowledge. | No abuse; exclusion upheld. |
| Was summary judgment proper without a causation expert? | Lay jury could infer causation without expert. | Causation in medical malpractice requires expert testimony. | Summary judgment proper; expert needed. |
| Did the court apply Daubert/KRE 702 correctly? | Court should consider all Daubert factors. | Court correctly applied reliability standards. | Yes; gatekeeping proper. |
