Antimerger Act

1950 consumer protection amendment to Section 7 of the clayton act that applied federal legislative barriers to corporate mergers that may impair or impede market competition, including mergers involving the acquisition of assets as well as stock; also called Celler-Kefauver Act. Section 7 of the Clayton Act had been previously limited to mergers involving only the acquisition of stock and therefore left a loophole that was closed by the Antimerger Act. See also antitrust acts; sherman antitrust act.
