355 U.S. 373 (1958)
Nashville Milk Co. v.
Does selling goods at different prices to different purchasers under substantially similar circumstances violate the Robinson-Patman Act?
Under the Robinson-Patman Act, it is unlawful for a seller to discriminate in price between different purchasers of commodities of like grade and quality, provided the discrimination causes injury to competition.
The court held that price discrimination in this instance did not violate the Robinson-Patman Act because Carnation Co. was able to demonstrate that the price differences were justified and did not result in harm to competition.
This case is significant because it highlighted the necessity for companies to have justifiable reasons for any price discrepancies to avoid antitrust violations. It also guided businesses in understanding how to prepare defenses based on legitimate operational cost differences or competitive pricing schemes. For law students and practitioners, the case offers compelling insights into assessing competitive injury and justifications under antitrust laws.
