Justices of the U.S. Supreme Court on Monday signaled that they may be considering a narrow ruling in Goldman Sachs’ appeal of a circuit court’s decision that allowed plaintiffs to proceed as a class in a closely watched securities case over conflicts on the investment bank’s board.

Goldman’s appeal, which aims to limit investors’ ability to proceed as a class in shareholder lawsuits, raised the question of to what extent companies can point to the “generic nature” of corporate statements as a way to defeat class certification in the suits.
