Rule Statements

To establish a violation of Section 1 of the Sherman Act, a plaintiff must demonstrate that the defendant possessed market power in a relevant market.

Without proof of a relevant market and market power, a plaintiff cannot establish that a defendant's conduct harmed competition.

Scenario: A small business owner believes a larger competitor is engaging in anticompetitive practices that are driving them out of business.

Your Rights: You have the right to sue for antitrust violations if you can prove that the competitor has significant market power and their actions are harming competition.

What To Do: Consult with an antitrust attorney immediately to assess the viability of your claim, gather evidence of market definition and market power, and understand the complex legal requirements.

Is it legal for a large company to offer lower prices than its competitors?

Depends. Offering lower prices is generally legal and often a sign of healthy competition. However, it can become illegal if the company has significant market power and is using predatory pricing to drive competitors out of business with the intent to later raise prices.

This applies to federal antitrust laws enforced by federal courts.

For Small businesses

Small businesses alleging anticompetitive harm must be prepared to present robust evidence defining the relevant market and demonstrating the defendant's market power, as failure to do so will likely result in dismissal of their claims, as seen in Mr. Dee's case.

For Large corporations

Large corporations facing antitrust scrutiny must still defend against claims by demonstrating a lack of market power or a properly defined market, but this ruling reinforces that plaintiffs bear a significant initial burden of proof.
