The Utah Pie Company made and sold frozen pies in the Salt Lake City area. It was very successful and soon had two thirds of the frozen-pie market in that area. In response to the loss of their market shares, three large pie makers-Carnation, Pet, and Continental-cut their prices in the Salt Lake area but not elsewhere. As a result, their sales picked back up and Utah Pie's fell to 45 percent of the market. The result was lower frozen-pie prices for consumers in that market. Utah Pie sued the other three companies for violating what part of the antitrust law? Did it win? [Utah Pie Co. v. Continental Baking Co., 87 S.Ct. 1326 (1967)]
