United States v. Container Corporation of America

Background

The United States sued a group of corrugated-container manufacturers in the Southeast, accusing them of exchanging current prices charged to identified customers. The complaint covered sales from 1955 to 1963 and noted that the defendants accounted for about 90% of regional shipments while the number of makers rose from 30 to 51.

Reasoning

The central question was whether the agreed practice of supplying a competitor, on request, with the most recent price for a specific customer unlawfully restrained competition. The Court held that the reciprocal sharing of customer-specific price information tended to stabilize prices and interfere with free market price setting, bringing the practice within the ban of §1 of the Sherman Act and reversing the dismissal below. Justice Fortas concurred, stressing that the record showed an actual effect on pricing, while Justice Marshall dissented, finding the evidence insufficient and noting easy entry and downward price trends.

Real world impact

The decision makes it unlawful for sellers in concentrated markets to exchange current, customer-specific price data when that sharing tends to limit price competition. Buyers and rival suppliers in similar industries may see fewer informal price disclosures and greater enforcement risk for coordinated information exchanges. The concurrence and dissent show that close factual proof of harmful effect mattered to some Justices.

Dissents or concurrances

Justice Fortas agreed with reversal but avoided labeling every such information exchange as automatically illegal; Justice Marshall would have affirmed the dismissal, finding the evidence of anticompetitive effect lacking.
