Congress passed the Sherman Act in 1980, and in 1914, the Clayton Act. Section 1 of the Sherman Act outlaws “every contract, combination in the form of trust or otherwise, or conspiracy, in restraint of trade or commerce among the several States, or with foreign nations.” Section 2 of the Sherman Act outlaws “monopolization, attempted monopolization, or conspiracy or combination to monopolize.”
Some acts are considered so harmful to competition that they are deemed “per se” illegal by courts. No defenses or justifications are allowed. These per se violations include, without limitation, horizontal agreements or understandings between competing businesses or individuals to fix prices or supply, rig bids, divide markets, effectuate group boycotts, share sensitive information, tie products or services, or engage in other types of collusion. Acts that are not deemed per se illegal may still violate antitrust laws under a “quick look” or “rule of reason” analysis.
Violations of the Sherman Act can result in both civil and criminal penalties. On the criminal side, individuals may be fined up to $1 million and face up to 10 years in prison, and corporations can be fined up to $100 million for a felony conviction. For civil cases, victims of antitrust violations may sue for treble damages — three times the amount of the damages suffered. Victims may also have defendants pay their attorneys’ fees because the antitrust laws allow for attorneys’ fee shifting for the benefit of prevailing parties. Attorneys representing plaintiffs often do so on contingency and through class actions.
