- Decided

- What it’s about

Summary: written with AI from the case record.

What it's about
The Supreme Court held that American Pipe tolling lets those class members bring individual claims later, but it does not let them start a successive class action outside the limitations period.
The decision limits repeated attempts to bring class actions after a court has refused to certify an earlier proposed class.
Question presented
Whether the American Pipe rule tolls statutes of limitations to permit a previously absent class member to bring a subsequent class action outside the applicable limitations period.
What the Court decided
Holding
Upon denial of class certification, a putative class member may not, in lieu of promptly joining an existing suit or promptly filing an individual action, commence a class action anew beyond the time allowed by the applicable statute of limitations. 857 F. 3d 994, reversed and remanded.
