Armed with lawyers from Boies, Schiller & Flexner and O’Melveny & Myers, Goldman Sachs & Co. scored back-to-back victories on Wednesday against former employees who burned their bridges with the investment banking behemoth in spectacular ways.

The first victory came in Goldman’s indemnification battle with Sergey Aleynikov, the senior programmer who helped Goldman build an aggressive high-frequency trading platform before his 2009 arrest for alleged corporate espionage. The U.S. Court of Appeals for the Third Circuit reversed an October 2013 decision ordering Goldman to front funds for Aleynikov to defend himself against criminal charges by the Manhattan district attorney.
