Customers who paid for text messaging on a per-use basis brought a class action under § 1 of the Sherman Act against AT&T, Verizon, Sprint, T-Mobile, and their trade association, The Wireless Association. They alleged that the carriers expressly agreed to raise their per-message prices, eventually moving their prices from roughly two to ten cents per message to twenty cents.
The case had previously reached the Seventh Circuit on an interlocutory appeal from the denial of a motion to dismiss. In that earlier appeal, the court held that the complaint was plausible under Twombly because it alleged parallel price increases, a concentrated market, trade-association information exchanges, falling costs, and a rapid shift toward uniform pricing. The court stressed, however, that this ruling allowed discovery; it did not establish that an unlawful agreement existed.
After three years of discovery, the district court granted summary judgment for the defendants. It concluded that the plaintiffs had not produced evidence sufficient to support a prima facie finding of an express agreement to raise per-use text-message prices. The plaintiffs appealed, relying principally on internal T-Mobile emails describing the price increases as “colusive” and opportunistic, as well as evidence of parallel pricing and trade-association contacts.
Issue #1
Whether the plaintiffs produced sufficient evidence at summary judgment to permit a reasonable jury to find an express price-fixing agreement in violation of § 1 of the Sherman Act.
Holding
No. The evidence showed parallel conduct consistent with tacit coordination, but it did not support a reasonable inference that the carriers expressly agreed to raise per-use text-message prices.
Reasoning
Section 1 condemns concerted action founded on an agreement, not merely firms' recognition that matching a competitor's pricing may be profitable. The plaintiffs therefore had to offer evidence from which a jury could infer express collusion rather than independent but parallel decisions in a concentrated market.
A small number of dominant firms can make a cartel easier to organize, but it also makes conscious parallelism easier. Firms in an oligopoly can observe public prices, anticipate rivals' reactions, and follow a price leader without communicating or committing themselves to a shared pricing plan.
The price increases occurred in a shrinking and unusual market. Heavy users were shifting to monthly or unlimited messaging bundles, leaving per-use service largely to infrequent users whose total monthly charges were small. A carrier could rationally conclude that raising a per-message price would generate more revenue without substantial customer loss, especially because many customers would not notice a modest increase or would move to the carrier's bundle plan rather than switch carriers.
The carriers did not move in the synchronized manner one would expect if their purpose were to eliminate all competitive alternatives through an agreement. Their increases occurred at different times, and price differences persisted for months. For example, T-Mobile's per-use price remained below Sprint's for much of the relevant period.
The plaintiffs' churn theory did not bridge the gap from parallelism to agreement. A profit-maximizing firm can benefit from a price increase despite losing customers, and firms engaging in tacit coordination necessarily accept the risk that a rival may not follow. Moreover, the record did not show that per-use messaging prices were an important driver of consumers' carrier choices or that lower-priced carriers gained meaningful market share.
Although express agreements may be proved circumstantially, the plaintiffs' evidence was equally consistent with lawful independent conduct. The absence of proof identifying an actual agreement, together with plausible business reasons for the pricing decisions, meant that the plaintiffs failed to make a prima facie case sufficient to survive summary judgment.
Issue #2
Whether T-Mobile executive Adrian Hurditch's emails referring to the price increases as “colusive” supplied direct evidence of an unlawful agreement or otherwise created a triable issue.
Holding
No. The emails reflected Hurditch's opposition to T-Mobile's pricing decisions and described lawful tacit collusion, not evidence that the carriers had expressly agreed on prices.
Reasoning
Hurditch wrote that he knew “the other guys are doing it” but that T-Mobile did not have to follow. That language is incompatible with knowledge of a binding or express interfirm agreement; it instead describes a firm observing rivals' public conduct and choosing whether to imitate it.
The word “colusive,” especially read with Hurditch's statements about price gouging, consumer reaction, and public relations, did not establish that he meant express conspiracy in the antitrust sense. His concern that the carriers were taking advantage of consumers could arise whether their behavior was coordinated by agreement or merely parallel.
Nothing showed that Hurditch had communicated with employees of the other carriers, participated in any conspiracy, or had personal knowledge of an agreement. A subordinate employee's characterization of corporate conduct cannot by itself prove an interfirm conspiracy when the surrounding communications point only to follow-the-leader pricing.
Hurditch's request that certain emails be deleted did not warrant an inference sufficient to defeat summary judgment. The record supported the equally plausible explanation that he wanted to remove emotional and career-endangering criticisms of T-Mobile management; moreover, the supposedly incriminating “colusive” email itself was not destroyed.
Issue #3
Whether the defendants' trade-association meetings and exchanges of information supported an inference that the carriers used the association to agree on per-use text-message prices.
Holding
No. The meetings created opportunities for contact, but the plaintiffs offered no evidence that the defendants exchanged pricing plans or reached an agreement at those meetings.
Reasoning
Trade-association membership and information exchanges are not inherently unlawful. Such practices can facilitate collusion, which made them relevant at the pleading stage, but at summary judgment the plaintiffs needed evidence connecting the meetings to an actual agreement on prices.
Representatives of companies outside the alleged conspiracy commonly attended the association and caucus meetings. One of the plaintiffs' own experts acknowledged that the presence of nonconspirators would greatly reduce the likelihood that the meetings served as a forum for unlawful price fixing.
An AT&T executive's statement that companies tried not to surprise one another and gave the group a heads-up about major actions suggested that competitors monitored each other and exchanged useful industry information. It did not show that they agreed on per-use messaging prices.
The timing also did not support the proposed inference. The meetings were not followed by simultaneous or near-simultaneous price increases, and the plaintiffs had no evidence of what pricing information, if any, was actually exchanged. Opportunity to conspire without evidence of an agreement is insufficient under § 1.
Issue #4
Whether the Sherman Act treats tacit collusion or conscious parallelism as unlawful price fixing.
Holding
No. Tacit collusion, including firms independently following a competitor's price increase, is not a § 1 violation absent an agreement.
Reasoning
The court distinguished express collusion, which is illegal because competitors agree not to compete, from tacit collusion, in which firms independently converge on profitable prices after observing market conditions and one another's conduct. Only the former supplies the agreement required by § 1.
Treating tacit coordination as illegal would effectively require courts to regulate how aggressively firms must compete and what prices they may charge. That approach would resemble public-utility price regulation rather than antitrust enforcement and could discourage entry into concentrated markets.
Competitors in concentrated markets commonly watch each other closely and copy successful business responses. A firm may follow a rival's higher price because it believes the rival has better information, fears retaliation, or expects the higher price to be profitable; none of those independent judgments establishes a conspiracy.
