During the testimony of former Dewey & LeBoeuf corporate partner John Schwolsky on Wednesday, the defense for three former executives of the now-defunct firm sought to characterize Schwolsky’s departure to Willkie Farr & Gallagher as a catalyst that propelled Dewey into bankruptcy two months later.

Schwolsky lead a transactional insurance practice with fellow partners Alexander Dye and Michael Groll that was profitable for Dewey & LeBoeuf, as it had been for legacy firm LeBoeuf, Lamb, Greene & MacRae before it merged with Dewey Ballantine in 2007, the witness testified.
