On October 3, 2007, the Ohio Supreme Court announced its decision in Terry v. Caputo (Case No. 2006-0705). The Supreme Court summary indicates that the Court "held that in order to establish a prima facie claim that a medical condition was the result of exposure to a toxic substance, the plaintiff in a civil lawsuit must establish by means of expert testimony (1) that the toxin is capable of causing the medical condition (general causation); and (2) that the toxic substance in fact caused the claimant's condition (specific causation)." This case involved a suit by 15 employees who sued their employer, the Ottawa County Board of Mental Retardation and Developmental Delay (MRDD), alleging that they were exposed to mold and other irritants at work that caused them a large number of medical problems. Their respiratory expert tied their conditions to their work environment.
