Narrative Opinion Summary
In the case of Mulholland v. DEC International Corporation, the Michigan Supreme Court reviewed a directed verdict in a product liability action concerning the installation of a milking system on a dairy farm. The plaintiffs, owners of the farm, alleged that the milking equipment, supplied by DEC and installed by Tommy's Refrigeration Service, caused their dairy herd to suffer from mastitis. A central issue was the trial court's exclusion of Sidney Beale, a non-veterinarian expert, from testifying on the causation of mastitis, which led to the plaintiffs' inability to prove their case. Beale, despite lacking veterinary credentials, had substantial experience with milking machinery and its effects on dairy herds. The trial court's decision to exclude Beale as an expert was based on his lack of licensure, contrary to Michigan Rule of Evidence 702, which allows qualifications through knowledge and experience. The Supreme Court found this exclusion erroneous, stating that the evidence presented was sufficient to withstand a directed verdict. The court reversed the judgments of the lower courts, remanding for further proceedings, emphasizing that expert testimony should not be excluded solely for lack of formal licensing when practical expertise is evident.

Reasoning: The ruling is challenged on the basis that MRE 702 permits qualification as an expert through knowledge, skill, experience, training, or education, without necessitating a license.
