Elements of Clayton Act

Quick Answer

What are the elements of Clayton Act?

Enacted in 1914, the Clayton Act aims to supplement the Sherman Act by specifically outlawing certain anticompetitive practices, including price discrimination, exclusive dealings, and mergers and acquisitions that may substantially lessen competition. It provides for both civil and criminal penalties for violations related to antitrust conduct.

Required Elements

1. Antitrust Injury

A plaintiff must demonstrate that a specific antitrust injury occurred due to the defendant's violation of the Clayton Act.

What to prove: The plaintiff must show that the defendant's anticompetitive behavior directly resulted in an injury to competition or consumers.

2. Violation of Prohibited Conduct

The plaintiff must identify a specific type of prohibited conduct under the Act, such as price discrimination, exclusive dealings, or an unlawful merger.

What to prove: Evidence must be presented that demonstrates how the conduct in question meets the criteria for violation laid out in the Clayton Act.

3. Market Impact

The conduct must substantially affect interstate commerce or competition in a relevant market.

What to prove: It must be shown that the anticompetitive effects of the conduct had a tangible impact on the market or consumers at a national level.

Burden of Proof

The plaintiff bears the burden of proof to show entitlement to relief and must meet the preponderance of the evidence standard.
