Deloitte was dismissed in June of 1997 after issuing a going concern opinion and a restatement of several years financial results that forced the withdrawal of their audit opinions for 1996 and prior.
As far as we know, there have been no civil, criminal, or disciplinary proceedings initiated against audit firms or audit partners for the audit failures and bankruptcies, forced acquisitions and government bailouts of Lehman Brothers, Bear Stearns, Merrill Lynch, Washington Mutual, New Century Financial, Countrywide, American Home, and on, and on.
