Shady Grove Orthopedic Associates, P. A. v. Allstate Insurance
The Supreme Court ruled that a New York law barring class actions for lawsuits seeking statutory penalties cannot block a federal class action, because Federal Rule of Civil Procedure 23 governs class certification in federal court and validly authorizes the suit.
The splintered decision reshapes how federal courts decide whether state limits on lawsuits survive when they clash with federal procedural rules, reinforcing that federal rules control unless they exceed Congress's rulemaking authority.
“Rule 23 unambiguously authorizes any plaintiff, in any federal civil proceeding, to maintain a class action if the Rule’s prerequisites are met.”
The Court's core holding that Rule 23 controls class certification regardless of contrary state law.
How it got here: A federal trial court dismissed the suit for lack of jurisdiction because a New York law barred the class action; the Second Circuit affirmed, and Shady Grove asked the Supreme Court to review the case.
The Case in Depth
What happened
Shady Grove, a medical provider, treated a car-accident patient who assigned it her rights to insurance benefits from Allstate. Allstate paid the claim late and refused to pay the interest New York law requires on overdue payments. Shady Grove sued Allstate in federal court, seeking to represent a class of everyone Allstate had similarly shortchanged, though its own claim was worth only about $500.
The question before the Court
Could a New York law banning class actions for suits seeking statutory penalties stop a lawsuit from proceeding as a federal class action under Federal Rule of Civil Procedure 23?
The Court's answer
No -- the Court ruled that Federal Rule of Civil Procedure 23, not the New York law, controls whether Shady Grove's lawsuit could proceed as a class action in federal court. Rule 23 directly answers the question by permitting a class action whenever its own listed requirements are met, and the New York law tried to answer that same question differently, so the two could not coexist.
Because Rule 23 truly regulates court procedure -- deciding how claims are processed rather than changing anyone's underlying legal rights -- applying it did not violate the federal law limiting the Supreme Court's rulemaking power. As a result, Shady Grove's proposed class action was allowed to go forward despite New York's rule against class actions for cases like this one.

Why it matters
Insurance companies and other businesses sued in federal diversity cases can now face class actions seeking statutory penalties even in states like New York that bar such suits in their own courts. The ruling makes federal court a more attractive forum for plaintiffs seeking large aggregated damages, and it clarifies how far the Federal Rules of Civil Procedure can override differing state litigation rules.
What changes now
The case is sent back to the lower courts, where Shady Grove's proposed class action can proceed under Rule 23's standards rather than being barred by the New York law. This is a final merits ruling on which law controls, though the district court will still need to decide separately whether the class actually meets Rule 23's certification requirements and other jurisdictional prerequisites.
What this does not decide
The Court did not decide whether state laws that cap damages within an already-certified class action, rather than barring the class action's existence altogether, would also be overridden by Rule 23. It also left open whether the class here actually satisfies Rule 23's certification requirements or the amount-in-controversy rules for federal jurisdiction.
Concurrences and dissents
Concurrence in part — Justice Stevens
Justice Stevens agreed Rule 23 applies here and joined the Court's opening sections, but rejected Justice Scalia's view that only the Federal Rule's own character matters. He argued some state rules, though procedural in form, are so bound up with defining a state's substantive rights or remedies that they must survive despite a conflicting Federal Rule. He concluded New York's §901(b) was not such a rule, so Rule 23 still controls.
Dissent — Justice Ginsburg
“The Court today approves Shady Grove’s attempt to transform a $500 case into a $5,000,000 award, although the State creating the right to recover has proscribed this alchemy.”The dissent's central objection that the ruling lets a federal rule override New York's damages limit.
Justice Ginsburg argued Rule 23 and New York's law do not truly conflict because Rule 23 governs only the procedural mechanics of class litigation while §901(b) defines the size of the remedy available, a substantive limit New York was entitled to set. She would have read Rule 23 with sensitivity to that state policy, avoided the conflict, and affirmed the Second Circuit's judgment barring the class action.
How the Court got there
The legal reasoning, step by step
- The Court applied a two-step framework: first ask whether a Federal Rule of Civil Procedure actually answers the disputed question, and if so, whether applying it exceeds Congress's rulemaking authority under the Rules Enabling Act, the law authorizing the Supreme Court to set procedural rules for federal courts.
- Comparing the texts, the Court found that Rule 23 and the New York law both directly answer the same question -- whether a lawsuit like this one may proceed as a class action -- because Rule 23 says a class action 'may be maintained' when its criteria are met, while the state law says such a suit 'may not be maintained' as a class action.
- Because the two provisions gave opposite answers to the identical question, the Court held there was a direct conflict, rejecting the argument that the state law addressed a separate 'eligibility' question that Rule 23 left untouched.
- The Court then asked whether Rule 23, so construed, violated the Rules Enabling Act's requirement that procedural rules not 'abridge, enlarge, or modify any substantive right.' Applying the longstanding test from Sibbach v. Wilson & Co., the Court asked only whether the Federal Rule itself really regulates procedure -- not whether the state law it displaces serves substantive goals.
- Because allowing plaintiffs to combine their claims in a class action, like other joinder rules, leaves the parties' underlying legal rights and remedies unchanged and only changes how claims are processed together, the Court concluded Rule 23 regulates procedure and is valid even though it may result in vastly larger stakes.
- Having found Rule 23 valid and controlling, the Court concluded that it displaces the New York law in federal diversity suits, regardless of the state's purpose in enacting that law.
