The "Fair Prices for Local Businesses Act" significantly amends the Clayton Act to strengthen prohibitions against price discrimination. It broadens the scope of these prohibitions by extending them from "in commerce" to "in commerce or in any activity affecting commerce." Crucially, the bill expands the types of transactions covered, now including products or services instead of being limited to commodities or goods. This aims to provide more comprehensive protection against unfair pricing practices. A major change is the removal of the "meeting competition" defense, which previously allowed sellers to justify lower prices by matching a competitor's offer. The bill also clarifies that liability for price discrimination extends to those who induce or receive the benefit of such discrimination. However, for persons with annual retail sales exceeding $100 billion, liability for inducing or receiving discrimination only applies if they acted knowingly. Furthermore, the Act simplifies the process for plaintiffs to recover damages in price discrimination cases. It establishes a conclusive presumption that a plaintiff unlawfully discriminated against has sustained injury and damages equal to the monetary amount of the discrimination. Plaintiffs are also permitted to establish additional damages beyond this presumed amount, if applicable. The bill also broadly defines "purchase" and "purchaser" to encompass various forms of exchange for products or services.
