Hall Street Associates, L. L. C. v. Mattel, Inc.
The Supreme Court ruled that federal arbitration law limits how thoroughly a court can review an arbitrator's decision, and that companies cannot contract around those limits by agreeing a judge should double-check the arbitrator's legal conclusions.
The decision resolves a split among federal appeals courts over whether parties could expand judicial review of arbitration awards by contract, but leaves open whether other legal routes, like state law or a court's own case-management power, might still allow broader review.
“Instead of fighting the text, it makes more sense to see the three provisions, §§9-11, as substantiating a national policy favoring arbitration with just the limited review needed to maintain arbitration’s essential virtue of resolving disputes straightaway.”
The Court's core reasoning for treating the statute's review grounds as exclusive.
How it got here: A federal district court twice applied the parties' agreed legal-error review standard; the Ninth Circuit reversed based on its own arbitration precedent; Hall Street asked the Supreme Court to review.
The Case in Depth
What happened
A landlord and a toy company were fighting over who should pay for cleaning up chemical pollution at a former manufacturing site the company had leased. After a trial resolved part of the dispute, the parties agreed to arbitrate the cleanup-cost claim, and asked the court to let a judge overturn the arbitrator's decision if the arbitrator got the law wrong.
The question before the Court
Can two companies write their arbitration contract to let a judge overturn the arbitrator's decision just because the arbitrator got the law wrong?
The Court's answer
No — the Court ruled that the federal arbitration law's fast-track process for confirming, vacating, or modifying an arbitration award allows review only on the specific grounds spelled out in the statute, such as fraud or an arbitrator exceeding his authority. Parties cannot add a private agreement giving courts power to undo an award simply because the arbitrator made a legal mistake.
The Court did leave open whether parties might still get broader review through some other legal route, such as state law or a court's general authority to manage its own cases, and sent the case back for the lower courts to consider those separate questions, which had not been addressed before.

Why it matters
Businesses that write arbitration clauses into contracts can no longer rely on those clauses to guarantee a court will double-check an arbitrator's legal reasoning under the federal arbitration statute. Companies wanting more searching review of arbitration awards may need to look to state law or other authority instead, and arbitration awards will generally stick even if a court thinks the arbitrator made a legal mistake.
What changes now
The case goes back to the lower courts to consider issues the Supreme Court did not resolve, including whether the arbitration agreement here could instead be treated as an order under a court's own case-management authority, independent of the federal arbitration law. This is a final ruling on the exclusivity question, but the broader dispute over how the award can be reviewed remains open on remand.
What this does not decide
The Court did not decide whether parties can get expanded judicial review of arbitration awards through routes outside the federal arbitration law's fast-track process, such as state contract or arbitration law, or a court's own case-management authority. Those questions were left open for the lower courts to address on remand.
Concurrences and dissents
Concurrence in part — Justice Scalia
Justice Scalia joined the entire majority opinion except for footnote 7, which traced the FAA's legislative history to bolster the textual reading. He did not explain his disagreement, but his vote otherwise fully supported the Court's holding that the statutory grounds are exclusive.
Dissent — Justice Stevens
“Today, however, the Court holds that the FAA does not merely authorize the vacation or enforcement of awards on specified grounds, but also forbids enforcement of perfectly reasonable judicial review provisions in arbitration agreements fairly negotiated by the parties and approved by the district court.”Stevens's central objection to the majority's exclusivity holding.
Justice Stevens argued the FAA's purpose was to make arbitration agreements enforceable as written, so courts should honor a fairly negotiated provision allowing review for legal error rather than treating the statute's listed grounds as a ceiling. He viewed the FAA's grounds as a shield protecting arbitration from hostile courts, not a limit on what parties can agree to, and would have had the Ninth Circuit affirm the award.
Dissent — Justice Breyer
Justice Breyer agreed with the majority and Justice Stevens that the FAA does not bar enforcing an agreement allowing review for legal error. Unlike the majority, he saw no need to send the case back for further proceedings and would have simply directed the Ninth Circuit to affirm the district court's judgment enforcing the arbitrator's award.
How the Court got there
The legal reasoning, step by step
- The federal arbitration law sets out specific, narrow grounds — like fraud, arbitrator misconduct, or exceeding authority — under which a court can vacate or modify an award through the law's fast-track review process, and separately says courts 'must' confirm an award unless one of those grounds applies.
- The Court applied the old interpretive principle that when a list of specific serious wrongs appears without a broader catch-all phrase, the list should not be read as open to additions — the listed grounds all describe egregious misconduct, and an ordinary legal mistake is not 'cut from the same cloth.'
- The Court examined Wilko v. Swan, a prior case Hall Street relied on for the idea that courts had long recognized extra grounds for review beyond the statute, and found its language too vague to support that reading, and in some ways actually opposed to expanding review for ordinary legal errors.
- The Court concluded that although parties can shape many features of arbitration by contract — such as who arbitrates and what procedures apply — nothing in the statute's text lets them rewrite how searchingly a court reviews the outcome once arbitration is over.
- Because the fast-track review process created by the statute has a fixed, limited set of grounds, the Court held that parties cannot use a private agreement to add 'review for any legal error' as a new ground within that process.
