U.S. Trustee Tracy Hope Davis on Friday objected to the retention of law firms and public relations advisers that had filed applications to advise Dewey & LeBoeuf in its bankruptcy proceedings, Reuters reported on Friday. Davis objected to the applications of law firms Proskauer Rose LLP and Keightley & Ashner LLP, arguing that the case does not "warrant the need for two law firms to perform what appear to be the same services." Dewey, the trustee's filing said, sought to employ both firms to advise on claims brought by the firm's largest unsecured creditor, the U.S. Pension Benefit Guaranty Corporation. The U.S. Trustee also questioned whether Proskauer has conflicts in representing Dewey.
