Koppers, Inc. v. Kelvin Trotter, Nathane Davis, Lonzo Allen, and Ken Piggee

Summary

The court held that the circuit court's class-certification order was inadequate because it merely stated that the requirements of Rule 23 were satisfied without analyzing the six certification factors or defining the class claims, issues, or defenses. Because the deficient order prevented meaningful appellate review, the court remanded with instructions to enter an order complying with Rule 23.
