Sherman Anti-Trust Act

Concerted Action



Section one of the Sherman Act prohibits concerted action, which requires more than a unilateral act by a person or business alone. The Supreme Court has stated that an organization may deal or refuse to deal with whomever it wants, as long as that organization is acting independently. But if a manufacturer and certain retailers agree that a manufacturer will only provide products to those retailers and not to others, then that is a concerted action that may violate the Sherman Act. A company and its employees are considered an individual entity for the purposes of this act. Likewise, a parent company and its wholly owned subsidiaries are considered an individual entity.



Evidence of a concerted action may be shown by an express or written agreement, or it may be inferred from CIRCUMSTANTIAL EVIDENCE. Conscious parallelism (similar patterns of conduct among competitors) is not sufficient in and of itself to imply a conspiracy. The courts have held that conspiracy requires an additional element such as complex actions that would benefit each competitor only if all of them acted in the same way.

Joint ventures, which are a form of business association among competitors designed to further a business purpose, such as sharing cost or reducing redundancy, are generally scrutinized under the Rule of Reason. But courts first look at the reason that the JOINT VENTURE was established to determine whether its purpose was to fix prices or engage in some other unlawful activity. Congress passed the National Cooperative Research Act of 1984 (15 U.S.C.A. §§ 4301-06) to permit and encourage competitors to engage in joint ventures that promote research and development of new technologies. The Rule of Reason will apply to those types of joint ventures.
