JPMorgan Chase & Co (JPM.N) on Friday won the dismissal of a U.S. whistleblower lawsuit filed by a former vice president who claimed the bank ignored red flags about a client’s potential fraud, even after authorities exposed the massive Ponzi scheme operated by longtime JPMorgan client Bernard Madoff. U.S. District Judge Robert Sweet in New York granted the bank’s motion to throw out the complaint, finding that Jennifer Sharkey had failed to demonstrate that her termination in August 2009 was in retaliation for speaking out.
