Kathleen Hackett, a consumer of bread purchased at retail, filed a complaint under Section 4 of the Clayton Act, 15 U.S.C. Â§ 15 (1971) seeking treble damages, costs and attorneys fees from the defendants for their alleged violation of Sections 1 and 2 of the Sherman Antitrust Act, 15 U.S.C. Â§Â§ 1 and 2 respectively. The defendants are seven bakers of pan-baked bread who sell such bread through various channels of distribution in the Philadelphia market area. Mrs. Hacketts complaint seeks recovery for injury to herself and to all other members of a class whom she claims to represent, consisting of all individual consumers in the Philadelphia market area who have purchased pan-baked bread from retail stores for their own consumption or for consumption by members of their family. The parties agree that her individual claim is for roughly nine dollars. She asserts that some one and one-half million purchasers of bread from retail stores, who purchased the bread involved for the use of some six million consumers comprise the class, of which she claims to be an appropriate class representative.
