Pacific Bell Telephone Co. v. Linkline Communications, Inc.
The Court ruled that a company cannot bring an antitrust "price squeeze" claim against a competitor that has no legal duty to sell it wholesale supplies in the first place. Because the wholesale-price and retail-price components of the claim each failed on their own under existing antitrust rules, combining them did not create a new, valid claim.
The decision forecloses a theory that several lower courts had allowed telecom and internet resellers to use against dominant network owners, meaning companies squeezed between wholesale and retail prices must instead show either an unlawful refusal to deal or old-fashioned below-cost predatory pricing.
“Two wrong claims do not make one that is right.”
Summing up why combining a failed wholesale claim with a failed retail claim cannot create a new antitrust theory.
How it got here: A federal trial court and the Ninth Circuit let the price-squeeze claim proceed on interlocutory appeal; AT&T asked the Supreme Court to resolve a circuit split over the claim's validity.
The Case in Depth
What happened
AT&T owns much of the infrastructure needed to provide DSL internet service in California, including the "last mile" lines connecting homes to the phone network. As a condition of a merger, AT&T had to sell wholesale DSL transport service to independent internet providers. Four such providers sued AT&T, claiming it squeezed their profits by charging a high wholesale price for that transport service while charging a low retail price for its own competing DSL service to consumers.
The question before the Court
Could independent internet providers sue AT&T under antitrust law for squeezing their profits between a high wholesale price and a low retail price, even though AT&T had no legal duty to sell them wholesale service at all?
The Court's answer
No — the Court ruled that a "price squeeze" is not a valid antitrust claim under Sherman Act §2 when the defendant has no legal duty to sell wholesale supplies to the plaintiff in the first place. Because AT&T had no such duty, it was free to charge whatever wholesale price it wanted for DSL transport service, just as it could have simply refused to deal with the independent providers altogether without violating antitrust law.
The Court also found the retail side of the claim wanting: the providers never alleged that AT&T's own retail DSL prices were below cost or that AT&T could later recoup any losses, the two things a predatory-pricing claim requires. Since neither the wholesale complaint nor the retail complaint worked on its own, combining them into a "price squeeze" theory did not create a new, valid antitrust claim.

Why it matters
Companies that resell wholesale services bought from a dominant competitor — common in telecom, internet, and utility markets — cannot sue just because their profit margins get squeezed. They must instead prove the dominant firm had an antitrust duty to deal on better terms or that its retail prices were unlawfully predatory, both harder legal showings.
What changes now
The case returns to the district court, which must decide whether the plaintiffs' amended complaint states a valid claim under the tougher pleading standard the Court had recently adopted in Twombly, and whether the plaintiffs should get another chance to amend their complaint to allege a proper Brooke Group predatory-pricing claim. This is a final ruling on the price-squeeze theory itself, but the underlying lawsuit continues on remand.
What this does not decide
The Court did not decide whether the plaintiffs' amended complaint actually states a valid predatory-pricing claim under Brooke Group, or whether they should be allowed to amend further. Those questions, along with how the new Twombly pleading standard applies, are left for the district court to resolve on remand.
Concurrences and dissents
Concurrence — Justice Breyer
Justice Breyer agreed the Ninth Circuit's price-squeeze holding was wrong and would vacate and remand, but for narrower reasons tied to the fact that AT&T was a regulated common carrier whose wholesale rates were already subject to review as "just and reasonable." He argued that when a regulatory structure already polices anticompetitive harm, the costs of antitrust enforcement on top of that regulation likely outweigh the benefits. He would have let the district court decide only whether the plaintiffs could pursue a predatory-pricing claim, without embracing the majority's broader reasoning.
How the Court got there
The legal reasoning, step by step
- The Court explained that businesses are generally free to set their own prices and choose their own trading partners, and antitrust law only steps in for unilateral conduct in narrow situations, such as predatory pricing or an unlawful refusal to deal with rivals.
- Applying its earlier decision in Trinko, the Court held that a firm with no antitrust duty to deal with rivals at wholesale has no obligation to deal on terms those rivals would prefer, and that there is no meaningful antitrust distinction between disputes over price and disputes over service quality.
- Turning to the retail side, the Court applied Brooke Group, which requires a plaintiff alleging harmful low pricing to show both that the prices were below an appropriate measure of cost and that the defendant had a real chance of recouping any losses later; the complaint here alleged neither.
- Because the wholesale claim failed under Trinko and the retail claim failed under Brooke Group, the Court reasoned that stitching the two together as a "price squeeze" could not produce a valid claim that neither component could support on its own.
- The Court also cited institutional concerns, noting that recognizing price-squeeze claims would force courts to police both wholesale and retail prices at once with no clear "fair margin" standard, functioning like a rate-setting regulatory agency rather than a court.
- Finding no additional competitive harm from a price squeeze beyond what the duty-to-deal and predatory-pricing doctrines already address, the Court declined to recognize a new, independent theory of antitrust liability.
