In China Agritech, Inc. v. Resh, the U.S. Supreme Court held that putative class members cannot rely on equitable tolling to file new class actions under Rule 23 of the Federal Rules of Civil Procedure. Resh was the third shareholder class action suit filed against China Agritech, Inc. under the Securities Exchange Act of 1934. The plaintiffs in the two previous suits settled their claims after the court denied their motions for class certification.
