Antitrust Remedies

Introduction

Antitrust remedies serve the dual purposes of compensating victims of anticompetitive conduct and deterring future violations. The antitrust laws provide a comprehensive remedial framework encompassing government enforcement actions and private lawsuits. The available remedies include injunctive relief, structural remedies such as divestiture, monetary damages, and civil penalties. The choice of remedy depends on the nature of the violation, the characteristics of the market, and the goals of antitrust enforcement.

Government Enforcement Remedies

The Department of Justice may seek injunctive relief under Section 4 of the Sherman Act to prevent and restrain ongoing violations. Injunctions may prohibit specific conduct, require affirmative measures to restore competition, or mandate structural relief such as divestiture. In United States v. Microsoft Corp. (2001), the government sought a breakup of the company, but the D.C. Circuit rejected that remedy and instead imposed conduct remedies, including requirements to disclose APIs and prohibit retaliation against OEMs.

The FTC may seek injunctive relief under Section 13(b) of the FTC Act, as well as administrative remedies including cease-and-desist orders. The FTC may also seek disgorgement of ill-gotten gains, though the scope of this remedy has been narrowed by the Supreme Court in AMG Capital Management v. FTC (2021), which held that Section 13(b) does not authorize monetary relief.

Structural Remedies

Divestiture is the most potent structural remedy in antitrust law. In merger cases, divestiture of assets or business units may be required to preserve competition. The effectiveness of divestiture depends on the viability of the divested assets and the presence of a suitable purchaser. The antitrust agencies often require fix-it-first remedies, where the merging parties propose divestitures that the agencies approve, avoiding litigation.

In monopolization cases, structural remedies are rare but may be appropriate when conduct remedies are insufficient. United States v. AT&T (1982) resulted in the breakup of the Bell System into a long-distance company and seven regional operating companies. More recently, structural remedies have been proposed for digital platforms, including interoperability requirements, data portability, and even functional separation.

Private Damages: Treble Damages

Section 4 of the Clayton Act (15 USC § 15) authorizes private plaintiffs who have been injured by an antitrust violation to recover treble damages —three times the actual damages sustained—plus reasonable attorney’s fees and costs. Treble damages serve both compensatory and deterrent functions, encouraging private enforcement and punishing violators.

To recover treble damages, a plaintiff must prove: an antitrust violation, injury to its business or property, and that the injury was caused by the violation—an antitrust injury. The Supreme Court in Brunswick Corp. v. Pueblo Bowl-O-Mat (1977) held that antitrust injury must be injury of the type the antitrust laws were designed to prevent, not merely harm to an individual competitor.

Private Damages: Passing-On and Indirect Purchasers

A controversial issue in antitrust damages is the passing-on defense, where defendants argue that the plaintiff suffered no injury because it passed on overcharges to its customers. In Hanover Shoe v. United Shoe Machinery Corp. (1968), the Supreme Court rejected the passing-on defense in actions by direct purchasers, holding that the complexities of tracing overcharges would undermine antitrust enforcement.

In Illinois Brick Co. v. Illinois (1977), the Court extended this logic to hold that indirect purchasers —those who bought from direct purchasers who were overcharged—may not recover damages under federal antitrust law. However, many states have enacted Illinois Brick repealer statutes that allow indirect purchasers to recover under state antitrust law, creating the possibility of duplicative recovery for the same overcharge.

Consent Decrees

Consent decrees are settlements between the government and antitrust defendants that are approved by a court and have the force of a judicial order. The Tunney Act (15 USC § 16(b)-(h)) requires the government to publish proposed consent decrees in the Federal Register, accept public comments, and explain the decree’s competitive impact. The court must determine that the consent decree is in the public interest before entering it.

Consent decrees commonly include injunctive relief, compliance requirements, and reporting obligations. Failure to comply with a consent decree may result in contempt sanctions. Consent decrees are an efficient mechanism for resolving antitrust cases, allowing the government to obtain relief without the costs and uncertainties of litigation.

Conclusion

Antitrust remedies are a critical component of competition policy. The availability of treble damages encourages private enforcement, while structural remedies enable the government to address fundamental market problems. The choice among remedies—injunctive, structural, or monetary—requires careful consideration of the violation’s nature, market conditions, and the remedial goals of compensation and deterrence.
