A New York judge on Friday rejected Barclays Plc’s (BARC.L) effort to dismiss state Attorney General Eric Schneiderman’s lawsuit accusing it of defrauding clients about high-speed trading in its private “dark pool” trading platform. Justice Shirley Werner Kornreich of the State Supreme Court in Manhattan said it was premature to dismiss Schneiderman’s claim under the state’s Martin Act, a powerful anti-fraud law. “Traders are entitled to rely on material representations banks make about their dark pools,” the judge wrote.
