Reiter v. Sonotone Corp.

Background

A woman sued on behalf of herself and all U.S. purchasers of hearing aids made by five companies, alleging the makers fixed prices and related terms so buyers paid more. She sought threefold money damages and an injunction under Section 4 of the Clayton Act. The District Court said retail buyers could sue if they paid inflated prices; the Court of Appeals said ordinary consumers who bought for personal use lacked that right.

Reasoning

The Court focused on the words “business or property” in Section 4 and gave “property” its ordinary, broad meaning, which includes money. It relied on earlier decisions holding that paying too much because of wrongful conduct injures one’s property. The Court concluded a consumer whose money was diminished by anticompetitive conduct suffers an injury in property and may seek treble damages under the statute. The Court rejected the narrower view that only business or commercial losses qualify.

Real world impact

The ruling allows ordinary retail consumers to bring damage claims under Section 4 when they allege direct overcharges from antitrust violations, and it may make class actions more common. The Court acknowledged this could increase litigation and urged district courts to guard against frivolous suits and manage class certifications, while noting policy concerns belong to Congress. The case was reversed and sent back for further proceedings consistent with the opinion.

Dissents or concurrances

Justice Rehnquist joined the opinion but warned the decision could significantly increase consumer class litigation and produce outsized attorney recoveries, a problem he said Congress, not the courts, should address.
