ANNAPOLIS, Md. - After finding that a trial court erred when it applied the wrong test in determining whether an expert's methodologies and theories in relation to mold exposure and illness are generally accepted in the relevant scientific community, a Maryland appeals court on Aug. 29 reversed a decision holding that the expert's testimony was admissible (Montgomery Mutual Insurance Co. v. Josephine Chesson, et al., No. 2454, September Term, 2009, Md. App.; 2012 Md. App. LEXIS 94).
