Calling off an engagement is always messy. Two weeks after New York’s Dewey Ballantine and San Francisco’s Orrick, Herrington & Sutcliffe broke off talks that would have led to one of the biggest legal pairings in years, fallout from the failed negotiations continues to rain down.

Two more partners last week decamped from Dewey, raising the question of whether the departures will mark the tail end of an exodus of more than a dozen partners who have left the firm after it began merger talks with Orrick or if there are more to come.
