The Manhattan District Attorney’s Office said the evidence against former Dewey & LeBoeuf leaders amply supported a grand jury indictment, rebutting arguments that the ex-leaders expected Dewey to pay back money to banks and insurers.

“This was not some joy ride; the insurance companies and financial institutions were, even under the best of circumstances, to be separated from their money for years based on Dewey’s misstatements,” prosecutors said in court papers Friday.
