China Agritech, Inc. v. Resh
The Supreme Court ruled that once a court denies class certification, would-be class members cannot wait out the filing deadline and then start an entirely new class action from scratch — they can only join the existing case individually or sue on their own within the deadline.
The decision closes off a strategy some shareholders used to keep resurrecting failed class-action lawsuits years after the original deadline passed, reinforcing rules meant to get all potential lead plaintiffs into a case early rather than letting litigation drag on indefinitely.
“American Pipe does not permit the maintenance of a follow-on class action past expiration of the statute of limitations.”
The core holding limiting the tolling rule to individual claims, not new class actions.
How it got here: A federal trial court dismissed the third class action as untimely; the Ninth Circuit reversed and allowed it; the company asked the Supreme Court to review that ruling.
The Case in Depth
What happened
China Agritech shareholders sued the company three times over the same alleged stock fraud. The first two lawsuits, filed on time, were denied class-action status and eventually settled individually. A new shareholder, who had not participated in either earlier case, filed a third lawsuit — this time a year and a half after the normal filing deadline had passed — trying to revive the class claims.
The question before the Court
If a court says a proposed class action can't go forward, can a new plaintiff wait past the deadline and file a whole new class action anyway?
The Court's answer
No — the Court ruled that once a court says a proposed class action can't go forward, a new plaintiff cannot simply wait past the filing deadline and start an entirely new class action. The special rule that pauses deadlines while a class case is pending only protects people who join the existing lawsuit or file their own individual claim; it does not let someone relaunch class-wide claims later.
The Court reasoned that letting deadlines pause for repeated new class actions would let plaintiffs' lawyers keep the case alive indefinitely by finding a new lead plaintiff each time an earlier attempt failed. Instead, anyone who wants to represent the class needs to step forward while the deadline is still running, not years afterward.

Why it matters
Shareholders and other class-action plaintiffs can no longer sit on the sidelines through two failed attempts at certifying a class and then file a third one after the deadline has passed. This pushes people who want to represent a class to step forward early, and it protects companies and defendants from facing fresh class claims years after the clock should have run out.
What changes now
The case goes back to the lower courts, where the third lawsuit's class claims will be treated as too late to proceed. Shareholders in this case may still be able to pursue individual claims if timely, but the class-action route is closed. Going forward, potential class representatives in similar cases will need to come forward promptly rather than waiting for earlier attempts to fail.
What this does not decide
Justice Sotomayor's concurrence stresses that the majority's rule about diligence draws heavily on a securities-law notice procedure that doesn't exist in ordinary class actions. The majority does not address, and leaves open, whether the same result would apply to class actions outside that particular statute's coverage.
Concurrences and dissents
Concurrence — Justice Sotomayor
Justice Sotomayor agreed that this particular case, governed by the securities-fraud lead-plaintiff notice statute, was correctly decided, but she would not extend the no-tolling rule to ordinary class actions under Rule 23 generally. She argued that outside this statute, absent class members usually have no way of knowing about an earlier class action or a chance to become lead plaintiff, so treating them as non-diligent for not stepping forward is unfair. She would have left the broader question for another case.
How the Court got there
The legal reasoning, step by step
- The Court examined its own prior rule from American Pipe & Constr. Co. v. Utah, which pauses (or 'tolls') the filing deadline for people covered by a class action so they can later join the suit individually or sue on their own if the class request is denied.
- The Court explained that pausing the deadline for individual claims makes sense because it avoids forcing everyone to file duplicate protective lawsuits while waiting to see if the class is approved.
- But the Court reasoned that this logic doesn't carry over to brand-new class actions, because efficiency there is best served by having every potential lead plaintiff come forward at the very start of the case, not years later.
- The Court pointed to court rules and, for securities cases, a federal statute requiring early notice to potential lead plaintiffs, both of which are built around resolving who represents the class quickly rather than letting the case restart repeatedly.
- The Court concluded that a plaintiff who waits until after the deadline has already passed to file a new class action cannot be considered to have acted diligently, and allowing the practice would let plaintiffs stretch the deadline indefinitely by filing class action after class action.
- Applying this reasoning, the Court held that the pause on the deadline does not extend to cover an entirely new, later-filed class action.

Cases affected by this decision
Limits American Pipe & Constr. Co. v. Utah (414 U. S. 538)
Clarifies that its deadline-pausing rule covers only individual claims, not brand-new class actions filed after the deadline.
Distinguishes Shady Grove Orthopedic Associates, P. A. v. Allstate Ins. Co. (559 U. S. 393)
Says that case addressed a different problem — a state law banning class actions — not whether a late class action can be revived by tolling.
