Several requests made by advisers seeking to work for the Dewey & LeBoeuf estate have raised the ire of U.S. Trustee Tracy Hope Davis, who argues in an objection filed with the court Friday that—among other things—some of the advisers failed to adequately prove they do not have inherent conflicts in representing the defunct law firm and that several appear to be playing redundant roles in the bankruptcy.

Law firms including Proskauer Rose and lead bankruptcy counsel Albert Togut’s firm, Togut, Segal & Segal, along with restructuring firms Zolfo Cooper and Development Specialists Inc., and crisis communications firm Sitrick and Company, are among those that filed applications seeking bankruptcy court approval to work on the Dewey case on June 15. Many of the firms have already begun working for the bankrupt firm’s estate and are seeking retroactive approval, with hourly rates for those seeking court approval rising as high as $935 for Togut and $895 for Sitrick.
