Rockman v. Union Carbide Corp.
266 F. Supp. 3d 839
D. Maryland2017Background
- Plaintiff Jeffrey Rockman, a Maryland lawyer, was diagnosed with peritoneal mesothelioma and alleges three brief bystander asbestos exposures during home repairs in 1965, 1973, and 1976 involving Georgia‑Pacific "Ready Mix" joint compound containing Union Carbide Calidria chrysotile asbestos.
- Plaintiffs relied on three experts: Drs. Abraham and Frank (who offered specific‑causation opinions that those exposures caused Rockman’s peritoneal mesothelioma) and Dr. Brody (who endorsed an "each‑and‑every exposure"/cumulative‑exposure theory).
- Defendants moved to exclude the experts under Fed. R. Evid. 702/Daubert and for summary judgment on remaining counts (strict liability, negligence, and loss of consortium).
- The court found Plaintiffs’ experts relied on studies of high‑level occupational exposures and pleural (not peritoneal) mesothelioma, and did not quantify or tie chrysotile bystander exposures here to disease thresholds.
- The court excluded the specific causation opinions and any opinions premised on the "each and every exposure" theory as unreliable under Rule 702/Daubert; Plaintiffs conceded they could not survive summary judgment without those opinions.
- The court granted summary judgment for Georgia‑Pacific and Union Carbide on the remaining counts, independently concluding the brief, infrequent, and remote exposures alleged could not as a matter of law be a "substantial factor" under Maryland causation standards (Balbos factors).
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Admissibility of experts' specific‑causation opinions (Drs. Abraham, Frank) | Rockman: experts can attribute disease using epidemiology, Helsinki criteria, and cumulative reasoning even without precise dose quantification | Defendants: opinions rely on irrelevant/studied populations (pleural, amphibole, high‑dose) and lack a reliable methodology tying low‑level chrysotile bystander exposure here to peritoneal mesothelioma | Excluded: opinions unreliable under Rule 702/Daubert; methodology not testable, not peer‑supportive or generally accepted for this exposure/disease context |
| Admissibility of "each and every exposure"/cumulative theory (Brody, Abraham, Frank) | Rockman: any above‑background asbestos exposure contributes/cumulates and can be causative without precise dose assignment | Defendants: theory untestable, lacks peer‑review/known error rate, and has been repeatedly excluded; it collapses dose‑response causation | Excluded: theory fails Daubert/Rule 702 (not generally accepted, not reliably applied) |
| Summary judgment as to Georgia‑Pacific (strict liability, negligence, loss of consortium) | Rockman: bystander exposures to Ready Mix joint compound in three repairs caused mesothelioma | Georgia‑Pacific: exposures were brief, infrequent, remote; insufficient frequency/proximity/dose to be a substantial factor under Balbos | Granted: even absent Daubert exclusion, alleged exposures legally insufficient to establish substantial‑factor causation as matter of law |
| Summary judgment as to Union Carbide (same counts; and failure‑to‑warn) | Rockman: Union Carbide supplied Calidria chrysotile used in joint compound and thus is liable | Union Carbide: only minor % chrysotile in product, sold to intermediaries after 1970, warnings were OSHA‑compliant, and any extra warning would not feasibly prevent exposures four steps removed | Granted: exposures insufficient as a substantial factor; no actionable duty/warning given intervening distribution chain and lack of practical effect |
