Goldman Sachs Group Inc. won dismissal of a lawsuit brought by Landesbank Baden-Wuerttemberg over losses on $37 million in collateralized debt obligations. U.S. District Judge William Pauley III in Manhattan ruled today that the bank didn’t sufficiently back up its claims against Goldman Sachs, which underwrote Davis Square, a CDO collateralized by residential mortgage-backed securities in 2006, and against Los Angeles-based TCW Asset Management Co., which manages collateral for asset-backed securities.
