Correction: A version of this article appearing in the April, 2013 print issue of Corporate Counsel magazine was incorrectly accompanied by a photograph of David G. Lubben, rather than David J. Lubben, who was the former general counsel of UnitedHealth Group, Inc. David G. Lubben, whose photograph appeared, is a member of Illinois’ Davis & Campbell LLC, and has never worked at UHG (and accordingly had no involvement in the stock option backdating scandal described in the article). The below article has been revised to add Mr. Lubben’s middle initial. We regret the error.

The UnitedHealth Group Inc. hired a new chief legal officer in January, adding more movement to an already revolving door. With five chiefs in seven years (six if you count co–general counsel), the company’s legal department has had an unusually high turnover rate. And some experts say that this much instability isn’t good for a legal group—or healthy for a corporate management team.
