With a battle looming between Detroit and public pension funds representing retired city workers, the city on Monday added another law firm, Pepper Hamilton, to the roster of outside counsel working on its Chapter 9 filing. Meanwhile, a second firm, Clark Hill, confirmed it was ending its federal lobbying contract with the embattled city.

Deborah Kovsky-Apap, a corporate restructuring and bankruptcy partner with Pepper Hamilton in the Detroit suburb of Southfield, Mich., notified the court and U.S. Bankruptcy Court Judge Steven Rhodes of her role as counsel of record to the Motor City.
