On November 5, 2012, the United States Supreme Court will hear oral argument in two cases dealing with appeals in class action litigation: Amgen Inc. v. Connecticut Retirement Plans and Trust Funds, and Comcast Corp. v. Behrend. Professor Linda Mullenix has written analyses of each of these appeals for the ABA Preview of Supreme Court Cases. In Amgen [PDF link], the Court will determine whether plaintiffs must furnish addition proof at class certification to invoke the “fraud-on-the-market” presumption in securities class litigation. In Comcast [PDF link], the Court may address the standards for evidentiary proof during class certification proceedings. The Amgen and Comcast cases manifest the Court’s continuing interest in class action litigation since the Court’s 2011 landmark decision in Wal-Mart Corp. v. Dukes.
