Lamps Plus, Inc. v. Varela
The Court ruled that an ambiguous arbitration agreement cannot be read to allow class-wide arbitration, extending its earlier rule that silence on the issue isn't enough to show the parties agreed to it.
The decision blocks a California court's use of a common contract-interpretation rule—reading unclear terms against whoever wrote the contract—when doing so would produce class arbitration, reinforcing how difficult it now is for employees and consumers to band together against companies that drafted the arbitration clause.
“Neither silence nor ambiguity provides a sufficient basis for concluding that parties to an arbitration agreement agreed to undermine the central benefits of arbitration itself.”
The majority's core reasoning for barring class arbitration under an ambiguous contract.
How it got here: The district court compelled arbitration but ordered it on a classwide basis and dismissed the suit; the Ninth Circuit affirmed; Lamps Plus asked the Supreme Court to review that ruling.
The Case in Depth
What happened
A hacker tricked a Lamps Plus employee into revealing the tax information of about 1,300 workers, and a fraudulent tax return was later filed in employee Frank Varela's name. Varela sued Lamps Plus on behalf of himself and other affected employees. Like most Lamps Plus workers, he had signed an arbitration agreement when he was hired, and the company sought to force his claims into individual, rather than class-wide, arbitration.
The question before the Court
Could a company force an employee into individual arbitration when his employment contract was ambiguous—not silent—about whether class-action arbitration was allowed?
Why it matters
Employees and consumers bound by ambiguous arbitration agreements will now typically be forced into solo arbitration even when a neutral, long-standing contract rule would have favored group proceedings. Companies that draft these agreements gain more certainty that ambiguity will not be used against them to permit costly class arbitration, while workers pursuing small-dollar claims—like the data-breach victims here—lose a tool for banding together.
What changes now
The case returns to the lower courts, where Varela's claims will proceed through individual, rather than class, arbitration consistent with the Court's ruling. This is a final decision on the merits of the arbitration question, though the underlying data-breach claims themselves still must be resolved in arbitration. The dissenters urged Congress to revisit how the FAA treats employees' and consumers' ability to act collectively.
What this does not decide
The Court did not decide whether the availability of class arbitration counts as a "question of arbitrability" that courts, rather than arbitrators, must presumptively resolve — it noted the parties had already agreed a court would decide the issue. It also did not reach Justice Breyer's argument that the courts below lacked jurisdiction at all.
Concurrences and dissents
Concurrence — Justice Thomas
Justice Thomas would have reversed on narrower grounds, reading the agreement as unambiguously limited to bilateral arbitration rather than merely silent, so no preemption analysis was needed. He joined the majority's opinion despite his general skepticism of the Court's implied-preemption precedents, saying it correctly applied existing FAA case law.
Dissent — Justice Ginsburg
Justice Ginsburg, joined by Breyer and Sotomayor, argued the Court has drifted far from arbitration's consent-based origins, using the FAA to strip employees and consumers of the ability to band together against more powerful companies. She emphasized that mandatory arbitration clauses have proliferated and that individual claimants often cannot afford to pursue small claims alone.
Dissent — Justice Breyer
Justice Breyer argued that the Ninth Circuit, and therefore the Supreme Court, lacked jurisdiction to hear the case at all, because the FAA generally bars interlocutory appeals from orders compelling arbitration. He also joined Ginsburg's and Kagan's substantive dissents on the merits.
Dissent — Justice Sotomayor
Justice Sotomayor argued the contract was ambiguous and that California's anti-drafter rule properly resolved that ambiguity in favor of class arbitration. She criticized the majority for invading state contract law without first determining whether the contract was actually ambiguous.
Dissent — Justice Kagan
“In this case, the result is to disregard the actual contract the parties signed.”Kagan's central objection that the majority ignored the agreement's actual language.
Justice Kagan, joined by Ginsburg and Breyer in full and by Sotomayor as to Part II, argued the contract's broad language actually authorized class arbitration and that even if ambiguous, California's neutral anti-drafter rule should govern under ordinary FAA principles, since that rule doesn't discriminate against arbitration. She argued the majority's approach improperly displaced neutral state contract law.
How the Court got there
The legal reasoning, step by step
- The Court built on its earlier ruling in Stolt-Nielsen v. AnimalFeeds, which held that when a contract is silent about class arbitration, courts cannot assume the parties agreed to it — because arbitration rests on consent, not judicial guesswork, any obligation to arbitrate as a class needs an affirmative basis in the agreement itself.
- The Court explained that class arbitration is fundamentally different from the informal, individualized process the Federal Arbitration Act was designed to protect, since it is slower, more expensive, and raises due-process concerns for absent class members whose rights get decided without their direct participation.
- Extending that reasoning, the majority held that an ambiguous contract — one open to two reasonable readings — is no better than a silent one at showing the parties actually agreed to give up individualized arbitration for a class proceeding.
- The Court then evaluated the tool the Ninth Circuit had used to resolve the ambiguity, California's rule construing unclear contract terms against whoever drafted them (known as contra proferentem), and characterized that rule as resting on public-policy fairness concerns about bargaining power rather than on any effort to discover the parties' actual intent.
- Because applying that policy-driven state rule would import class arbitration without genuine consent, the Court held that doing so conflicted with the FAA's core principle that arbitration flows from agreement, so the rule was preempted in this context.
- The Court concluded that an ambiguous agreement, like a silent one, cannot supply the contractual basis required for class arbitration, so the anti-drafter rule could not substitute for that missing consent.
