Our January 16, 2014 entry entitled “Mold Up in the Air” discussed the pending appeal of Cornell v. 350 West 51st St. Realty LLC, a case which concerned whether a plaintiff could get to a jury on her claim that indoor residential mold caused her respiratory injuries. We pointed out that the Court of Appeal’s questioning at oral argument portended a potential reversal and defeat for mold plaintiffs. And that is in fact what has happened. The Court of Appeals (2014 NY Slip Op 02096) granted the defendant landlord and coop summary judgment, and dismissed the bodily injury claims of the Cornell plaintiff. The decision is a difficult read, but the lessons yielded are clear.
Some background: the plaintiff in Cornell alleged that throughout her occupancy of a co-op apartment, the co-op building's "basement was in a wet, damp, musty condition"; that the radiator in her apartment's living room "leaked on numerous occasions" and "continued to leak and also released steam into the Apartment" despite the co-op’s attempts at repair; that in July 2003 she first noticed and notified the co-op that "there was mold growing in the [apartment's] bathroom," but the co-op "ignored" this condition; and that beginning in the first week of October, 2003, the landlord and/or its contractor performed demolition and/or construction work in the basement of the co-op building, permitting noxious dust, dirt, mold and debris to be released, which infiltrated her first-floor apartment. What were her injuries? The Cornell plaintiff claimed that "[i]mmediately after" the landlord and/or its contractor performed the work in the basement, she became dizzy, disoriented, covered with rashes, unable to breathe, light-headed, congested, experienced tightness in her chest, had severe headaches, had shortness of breath, had a metallic taste in her mouth, and experienced other physical symptoms.
At the Frye hearing (brought on by defense motion), the defendants used an immunologist/epidemiologist who assessed plaintiff’s claim that "a significant portion of her physical and psychological problems is related to adverse reactions stemming from exposures to molds," and, after review of her medical records and the relevant science, opined with reasonable medical certainty that there was no relationship between the medical problems experienced by Ms. Cornell and exposures to molds (i.e., no specific causation). The defendants’ expert also opined that a causal relationship between indoor residential mold and Ms. Cornell’s injuries was not generally accepted in the medical community (i.e., no general causation).
Plaintiff’s medical expert opined to the contrary, and pointed to numerous studies that supported an association between indoor residential mold and illness. But as the Court of Appeals explained, “studies that show an association between a damp and moldy indoor environment and the medical conditions that [plaintiff's medical expert] attributes to Cornell's exposure to mold (bronchial-asthma, rhino-sinusitis, hypersensitivity reactions and irritation reactions of the skin and mucous membranes) do not establish that the relevant scientific community generally accepts that molds cause these adverse health effects.” (The causation/association battle line was explained in detail in our January 16 entry.)
The Court of Appeals could have ended its decision there (since without proof of general causation, plaintiff must be turned away), but it went further: even assuming that the plaintiff in Cornell demonstrated general causation, she did not show the necessary specific causation. (For a theory of causation to survive under Frye, both prongs of causation – general and specific – must be proved.) The Court of Appeals decision alludes to the fact plaintiff failed to show specific causation because she did not set forth “exposure to a toxin, that the toxin is capable of causing the particular illness and that plaintiff was exposed to sufficient levels of the toxin to cause the illness (specific causation)."
The Cornell plaintiff’s expert had tried to prove specific causation by differential diagnosis. The Court of Appeals dismissed that attempt: “Differential diagnosis, of course, 'assumes general causation has been proven'". This last pronouncement is of incredible importance to the defense of toxic tort claims, as the number of clinicians who use differential diagnosis to support an opinion on causation is legion.
This Firm already has had opportunity to use the Cornell decision at the trial court level to our client’s advantage (see Benton v 80 Cranberry Street, in “Publications” above). Absent a major change in the science of mold illness, there is every reason to believe the next few years will see many more summary judgment decisions in favor of land owners and against mold plaintiffs.
