Regarding the May 4 story, "Discount Stores Unsettled by Price Protection Ruling":
The Supreme Court's ruling that "a manufacturer does not automatically violate antitrust laws if it drops a discount retailer to protect another dealer from price competition" flies in the face of the congressionally enacted Clayton Antitrust Act and the Sherman Antitrust Act.
The Clayton Act--a 1914 amendment to the Sherman Antitrust Act--prohibits exclusive dealing contracts where the effect may be "substantially to lessen competition." The Sherman Antitrust Act prohibits any unreasonable interference to a "freely competitive pricing or distribution system" of the open market.
The victory for Sharp Electronics and its calculator dealer that charged higher prices can only tend to create a monopoly, unreasonably interfere with the distribution system and lessen competition, which, consequently, will artificially maintain calculator prices.
