Beleaguered law firm Dewey & LeBoeuf LLP suffered another departure from its leadership team, as bankruptcy specialist Martin Bienenstock prepared to move his practice to Proskauer Rose LLP, the Wall Street Journal reported today. Bienenstock recently worked to try and save the firm as part of a chairman's office created last month in a management overhaul. It remained unclear how Bienenstock and Dewey's other bankruptcy lawyers would integrate with Proskauer's restructuring practice and whether all of them would go.
