Dewey & LeBoeuf attorneys were tapped to represent the unsecured creditors' committee in the bankruptcy of bankrupt futures firm MF Global Holdings Ltd ("MFG"), according to 2 sources familiar with the matter. Dewey edged out competing firms that made pitches to represent the committe, including Brown Rudnick and Milbank Tweed Hadley & McCloy.  The 5-member committee, which includes JPMorgan Chase, Bank of America and Wilmington Trust, will advocate for unsecured creditors of MFG, which was forced into bankruptcy after bad bets on European debt. Dewey's restructuring group has represented both debtors and creditors.  The firm currently represents bankrupt bond insurer Ambac Financial Group, and also represented a group of shareholders in the bankruptcy of hotel owner Innkeepers USA Trust. JPMorgan, the agent for MFG's $1.2 billion syndicated line of credit, was named to the committee despite also having a $300 million secured loan against MFG's brokerage unit. That interest could conceivably position the bank against other unsecured creditors. Martin Bienenstock, who chairs Dewey's restructuring group and had attended Monday's meeting, did not immediately return a call seeking comment.  The firm also declined to comment. MF Global filed for bankruptcy protection on Monday, 10/31/11, after last-minute efforts to sell off assets were derailed by the discovery of $633 million in missing client money.  [reuters 11/9/11]
