Supreme Court Vacates Class Certification in Goldman Sachs Securities Suit on Narrow Grounds
When the U.S. Supreme Court granted the petition for a writ of certiorari to take up class certification questions raised in the long-running Goldman Sachs securities class action lawsuit, some commentators thought the case might give the Court the opportunity to reconsider fundamental issues about the presumption of reliance under the “fraud on the market” theory in connection with class certification in securities suits.
