A federal judge dismissed individual investors' securities claims against Vivendi related to ordinary shares they purchased on the Paris Bourse, finding that the claims are barred by the U.S. Supreme Court's decision in Morrison v.

Morgan Stanley and Discover have already exchanged a juicy set of briefs, but the battle is expected to escalate this week, when the bank answers Discover's charges of breach of contract and tortious interference.
