No General Causation? No Specific Causation? No Problem!

BNA Toxics Law Reporter reported on December 31, 2009, that a Michigan Appeals Court affirmed a mold exposure verdict for $303,260, finding that expert testimony was not necessary under Michigan State law to prove either general causation or specific causation.  In Genna v. Jackson, Mich. Ct. App., No. 285746, the Michigan Court Of Appeals (Oakland Circuit Court) affirmed the trial court's denial of defendant's post-judgment motion for judgment notwithstanding the verdict (JNOV) and for a new trial. Based upon a review of the decision, it is not disputed ( at least by this writer) that defendant's negligent conduct resulted in substantial  flooding in the plaintiffs' home and the gross mold contamination that resulted. Plaintiff's microbial expert identified two molds in the home--penicillum and aspergillus--which he testified at trial could affect human health and pose safety issues.  Plaintiffs' children began to experience what the court described as "flu-like symptoms including: diarrhea, vomiting, congestion and nosebleeds".  Over a period of months, these symptoms worsened and the symptoms did not respond to aggressive treatment.  Plaintiffs did not call an expert to testify that these symptoms were the result of the mold contamination. Nonetheless, the appeals court held that plaintiff did not have to demonstrate that the alleged toxin is "capable" of causing injuries like those suffered by the children, let alone requiring the plaintiffs to prove that these children's symptoms were caused by mold exposure. The court reasoned as follows: "This is not a complicated case: the children were removed from the home, the mold was discovered, and the children recovered".  Thus, the court based its decision on "circumstantial evidence that would 'facilitate reasonable inferences of causation, not mere speculation'."  With due respect to the appellate panel, which was obviously impressed with the graphic description of "patches of mold of all different colors all over the walls and ceilings in her kitchen, family room and dining area", this is a really bad decision and a potentially dangerous precedent in Michigan!  It is a mistake to base toxic tort causation on a temporal relationship,i.e., the "children were removed from the home, the mold was discovered, and children recovered."  Flu-like symptoms can be caused by......well, the flu.  That the children's symptoms went away could signify that they had recovered from a prolonged bout of the  flu. Based upon this court's reasoning, the children's illness could have been caused just as easily by lead paint poisoning, contamination of their drinking water, VOC's emanating from their carpeting,  formaldehyde in the walls....or just a really bad allergic reaction to the family's cats.  Did anyone check the family furnace for carbon monoxide gas?  It is not as if the symptoms that the children suffered from were unique to mold "poisoning". Moreover, no one appears to have apprised the trial court that it is not unusual that the antibiotics the children were administered did not cure a viral infection! We also suffer from flu-like symptoms all the time. It is not unusual, particularly in the frigid month of February in Royal Oak, Michigan, when this incident occurred, for these symptoms to occur and to persist in the absence of an exposure to toxic mold. The court faults the defendant for not submitting "any scientific evidence that the mold in her condominium could not have caused plaintiffs' injuries." (emphasis theirs).  And since when does the burden in a negligence case shift to the defendant, and to prove a negative no less? 

Mold In Our Classrooms

My hometown newspaper Greenwich Time, reported in a front page headline on March 25, 2009 "Mold found again at Ham Ave."  The Hamilton Avenue Elementary School in Greenwich was closed in 2005 largely due to the perception that mold made the school unsafe for students and faculty.  For the past three years, the youngsters attended classes in temporary modular classrooms, which ironically also suffered from mold problems, while awaiting completion of the oft-delayed reconstruction of the school, the Greenwich Time reported.   It was discovered last week at the newly re-opened school that a 2-to-3-square-foot patch of mold was discovered due to a leaky interior pipe that hadn't been properly sealed during construction. It is not surprising that the school's industrial hygienist, Hygenix, found "exceptionally low" levels of mold after sampling. What is surprising is that the decision was made to perform sampling at all considering that the source of the water infiltration was addressed and the mold removed.  Sampling is often not necessary and sampling results are frequently misinterpreted to suggest a health hazard where none exists.  In its guidance for "Mold Remediation in Schools and Contaminated Buildings", the USEPA cautions that there a number of pitfalls associated with mold sampling which at best only provides a "snapshot" of conditions as they exist at a given time.  To suggest, as the school's consultant did, however, that any "residual microbial hazards" had been eliminated is an unfortunate choice of words because it is probably the case that no hazard ever existed in the first place.  Ron Gots, a toxicologist based in Rockville, Maryland, who has written extensively about public misinformation about mold describes how medical statements by mold testers may result in unintended consequences in the event of a claim.  For example, the statement in a hygienist's report that "This mold is known to produce toxins which can cause a variety of adverse health effects including......"  is not only irrelevant, but begs the question whether:(1) the mold is producing toxins in this instance?; (2) those toxins are getting to people?; and (3)  they are getting to people in sufficient quantity to cause harm?  As Dr. Gots points out, the issue is not what molds can do; the question is what they are likely or proven to do under these particular circumstances in this setting.  To avoid further fear and confusion about mold (and unnecessary costs) at the Hamilton Avenue school,  a more scientifically objective approach should be considered by the Town.
