The Sherman Act: An Essential Guide for Business Compliance
The Sherman Act is the foundation of U.S. antitrust law, prohibiting contracts, combinations, or conspiracies that restrain trade and preventing monopolization. Understand the critical distinction between Section 1 (concerted activity) and Section 2 (monopolization), the severe civil and criminal penalties, and how robust compliance is your best defense against catastrophic litigation and regulatory enforcement.
For any business operating in the United States, understanding the Sherman Antitrust Act of 1890 is not optional—it is a fundamental requirement for risk management and operational sustainability. This foundational federal law is a comprehensive charter designed to preserve free and unfettered competition as the rule of trade. Violating its provisions can lead to devastating financial ruin, significant corporate disruption, and even imprisonment for individuals.
This guide offers a professional overview of the Sherman Act’s two core sections, outlines the most common and dangerous violations, and details the severe civil and criminal penalties you must avoid. A proactive compliance strategy is the most effective way to safeguard your company’s future.
The Sherman Act is structured around two key sections, each addressing a different type of anticompetitive behavior. It is essential to distinguish between them, as the legal standards and necessary evidence differ significantly.
Section 1 broadly prohibits “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”. Crucially, this section only targets concerted activity—meaning an agreement between two or more separate economic actors. A single company acting alone cannot violate Section 1.
Types of Concerted Activity Prohibited by Section 1:
Section 2 targets the act of obtaining or maintaining monopoly power through improper means. It makes it illegal for “Every person who shall monopolize, or attempt to monopolize, or combine or conspire with any other person or persons, to monopolize any part of the trade or commerce”.
Unlike Section 1, a violation of Section 2 can be based on the unilateral actions of a single dominant firm. However, merely having a monopoly is not illegal. The violation lies in acquiring or maintaining that power through exclusionary or anticompetitive conduct, rather than through superior product, business acumen, or historical accident.
Courts determine whether an action violates the Sherman Act using one of two standards:
Tip Box: The “Per Se” Rule
Certain anti-competitive conduct is considered so inherently harmful to competition that it is automatically presumed illegal, without any need to examine the practice’s actual market effect or a potential defense. The classic “hard core” offenses fall here.
The most common per se violations are horizontal agreements:
Most other restraints of trade are analyzed under the more flexible “Rule of Reason.” Here, the court conducts a deep, fact-intensive inquiry, weighing the practice’s procompetitive benefits against its anticompetitive harms to determine if the restraint is unreasonable. This often applies to complex vertical restraints like exclusive dealing or tying arrangements.
Antitrust liability under Section 1 does not require proof of a formal, written agreement. A discussion among competitors about a sensitive topic (like a price increase) followed by common action can be enough to convince a jury that an unlawful agreement existed. Evidence that could be consistent with lawful behavior is generally not enough, but plaintiffs can succeed with strong circumstantial evidence suggesting a conscious commitment to a common, unlawful scheme.
A violation of the Sherman Act carries both severe civil and criminal consequences, often running concurrently.
Type of Penalty | Individual Exposure | Corporate Exposure |
---|---|---|
Criminal (Felony) | Up to 10 years in federal prison and fines up to $1 million per offense. | Fines up to $100 million per offense, which may be increased to twice the gain or loss involved. |
Civil (Private Actions) | Private parties injured by an antitrust violation may sue to recover three times their damages (treble damages), plus attorney’s fees. | |
Government Civil Enforcement | Injunctions, consent decrees, and corporate divestiture. Enforcement is carried out by the Department of Justice (DOJ) and the Federal Trade Commission (FTC). |
While there is no acceptable defense for “per se” criminal antitrust violations, defense strategies in civil lawsuits can be crucial for reducing liability, negotiating a favorable settlement, or obtaining an advantageous ruling. Common civil defenses include:
Immediate consultation with an experienced Legal Expert is imperative upon the first notice of an investigation or lawsuit.
The best strategy against an antitrust violation is preventative compliance. Antitrust laws apply to businesses of all sizes, and a local market can easily be deemed a “relevant market” for assessment.
Caution: Trade Association Meetings
Competitor gatherings, such as trade association meetings, are high-risk environments. To avoid even the appearance of impropriety, refrain from discussing competitively sensitive information. If any discussion drifts towards price, marketing strategy, or market division, you must leave the conversation or meeting immediately and demonstratively.
A sound antitrust compliance program should include:
The Sherman Act is an ever-present force in the business world, and ignorance of the law is no defense. Robust compliance is an investment, not an expense.
Post Card Summary
The Sherman Act is the most powerful law ensuring fair competition. Section 1 prohibits agreements that unreasonably restrain trade, while Section 2 bans the illegal acquisition or maintenance of monopoly power. Violations are felonies punishable by massive fines and prison time, and they automatically expose a company to private lawsuits for triple the damages incurred. Compliance is non-negotiable.
A: A per se violation, such as price fixing, is so clearly anticompetitive that it is automatically illegal, and no defense is permitted. The Rule of Reason is a full market analysis used for less clear restraints, where a court weighs the anticompetitive harm against the procompetitive benefits.
A: Yes. While larger corporations are more often the target, antitrust law can apply to a local, small market. If a small business engages in prohibited conduct like bid rigging or price fixing, even in a small geographic area, it can still face severe criminal and civil penalties.
A: Enforcement is primarily carried out by the Department of Justice (DOJ) Antitrust Division (for both criminal and civil actions) and the Federal Trade Commission (FTC) (for civil actions under the FTC Act, which covers all Sherman Act violations). Private parties who are injured by a violation can also file civil suits.
A: Treble damages are a remedy available to private plaintiffs in a successful antitrust lawsuit. It means the plaintiff can recover three times (triple) the actual damages they sustained due to the anticompetitive conduct, plus attorney’s fees.
