This article is about the relationship between antitrust and consumer protection law. Its purpose is to define each area of law, to delineate the boundary between them, to show how they interact with each other, and to show how they ultimately support one another as the two components of a single overarching unity. That overarching unity is consumer choice. Antitrust and consumer protection law share a common purpose in that both are intended to facilitate the exercise of consumer sovereignty or effective consumer choice. Such consumer choice exists when two fundamental conditions are present: (l) there must be a range of consumer options made possible through competition; and (2) consumers must be able to select freely among these options.
