In RSR Corp. v. Hayes, 673 S.W.2d 928, 932-33 (Tex. App.--Dallas 1984, writ dism'd w.o.j.), the Fifth Court of Appeals decertified a class because common questions did not predominate over individual issues. See RSR, 673 S.W.2d at 933. Residential property owners had sued the owners of a lead smelter, claiming that airborne lead emissions caused personal injury and property damage. See RSR, 673 S.W.2d at 929. The owners alleged a variety of damages and several theories of liability. See RSR, 673 S.W.2d at 932-33. The trial court certified a class that included all property owners living within a two-mile radius from the smelter. See RSR, 673 S.W.2d at 929. The court of appeals reversed, holding that common issues did not predominate because some owners did not suffer any injury, the personal injuries alleged differed for each class member, and because the owners had asserted various theories of liability that could be answered differently among class members. See RSR, 673 S.W.2d at 932-33.
