Attorneys representing Goldman Sachs in a retaliation suit brought by a former in-house lawyer at the investment bank are seeking to litigate the case in arbitration.

Former in-house attorney Marla Crawford alleged in the lawsuit, filed late last month, that she had information about an inappropriate relationship between the head of litigation, Darrell Cafasso, and a junior attorney that she tried to provide during an internal investigation of Cafasso. When she expressed an interest in bringing that information forward she was given bad remarks in her performance review and was subsequently fired, she alleged.
