7:23-cv-00897
E.D.N.C.Jul 22, 2025Background
- The litigation arises from claims under the Camp Lejeune Justice Act (CLJA), allowing individuals exposed to contaminated water at Camp Lejeune to seek relief.
- The court structured expert discovery into three phases: Phase I (water contamination), Phase II (general causation), and Phase III (specific causation/damages).
- Plaintiffs’ Leadership Group (PLG) served Phase III expert reports after Phase II disclosures were due.
- The United States moved to exclude portions of Phase III reports, arguing they contained untimely general causation opinions that should have been served in Phase II.
- Plaintiffs argued those references were integral to their experts’ specific causation methodology, not new general causation opinions.
- The court had to decide whether Phase III reports improperly introduced new general causation opinions and, if so, what sanction was appropriate.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Whether Phase III reports included untimely general causation opinions | General causation material is necessary for specific causation analysis (e.g., differential diagnosis) | Phase III reports introduce new general causation opinions and analyses not disclosed in Phase II | Limited references to existing general causation evidence are permitted; new or independent analyses are excluded |
| Whether such inclusion violated scheduling orders | Incorporated general causation content is part of methodology, not new opinions | No new general causation opinions can be included after Phase II deadline | Only references to timely, previously disclosed general causation content allowed |
| Whether prejudice or unfair surprise results if new general causation analyses admitted | No surprise since references rely on already disclosed and established literature | New analyses create unfair surprise and discovery burden | No prejudice by referencing existing material; exclusion appropriate for new analyses |
| Appropriate sanction for violation | Lesser sanctions, not wholesale exclusion | Exclusion necessary to maintain court's phased schedule | Partial exclusion: Only new, independent general causation analyses are struck |
