54 F.4th 7
1st Cir.2022Background:
- Plaintiff Jamilet González-Arroyo sued Doctors' Center Hospital Bayamón and Dr. Benito Hernández-Diaz for negligent care during the birth of her son ALG, alleging perinatal oxygen loss caused autism and cerebral palsy.
- Plaintiff relied on an expert report by Dr. Barry Schifrin (written before formal discovery) that hypothesized fetal oxygen loss from contractions, placental abruption, or maternal hypotension after spinal anesthesia.
- At deposition, after being shown fetal monitoring strips (only up to ~10:40 AM), Schifrin conceded those strips showed no fetal stress up to that time and acknowledged he had not reviewed all monitoring before issuing his report; he did not timely supplement his report.
- Hospital's expert, Dr. Francisco Gaudier, reviewed strips through ~11:27 AM and concluded there was no evidence of perinatal oxygen loss; his report was not challenged by plaintiff.
- The district court granted defendants' motion in limine, excluding Schifrin's report as methodologically unreliable under Daubert/Rule 702 and for Rule 26 deficiencies, then granted summary judgment for defendants because plaintiff had no admissible expert on causation; a post-judgment amended expert report was filed but the district court denied reconsideration (the First Circuit affirms on the merits).
Issues:
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Exclusion of expert under Rule 702/Daubert | Schifrin used a reliable differential-diagnosis methodology and his timing uncertainty does not make his opinion inadmissible; defendants withheld monitoring strips | Schifrin opined without reviewing key medical data, made assumptions, failed to cite literature or specify national standard; unreliable under Daubert | Affirmed exclusion: district court did not abuse discretion—report rested on assumptions and showed an analytic gap from data to opinion |
| Spoliation/withholding of fetal monitoring strips | Hospital withheld or spoliated the last ~90 minutes of strips, preventing proper expert analysis | No record evidence of spoliation or formal discovery dispute; plaintiff failed to request missing strips on record | Rejected: argument waived or unsupported; record does not establish withholding/spoliation |
| Summary judgment after exclusion | Case could proceed relying on defendants' expert or other witnesses to establish causation without Schifrin | Without an admissible plaintiff expert, plaintiff cannot establish causation in a medical-malpractice suit under Puerto Rico law | Affirmed summary judgment: plaintiff failed to identify admissible evidence creating a triable issue on causation |
| Rule 59(e) motion and jurisdiction to consider amended report | District court should have considered Rule 59(e) motion and new amended Schifrin report; appeal notice did not divest court | Even if court could decide, the amended report is not newly discovered and could have been produced earlier; no manifest error shown | Denial of reconsideration affirmed on the merits: amended report not newly discovered and arguments merely rehashed previous positions |
