After presiding over the largest bankruptcy filing in U.S. history, former Southern District Bankruptcy Judge James Peck will become co-chairman of Morrison & Foerster’s global business-restructuring and insolvency group.

Peck, who will join as senior of counsel at MoFo on March 3, oversaw the Chapter 11 and SIPA cases of Lehman Brothers and its affiliates, which collectively held about $600 billion assets at the time of filing. He also presided over Chapter 11 cases of Iridium, Quebecor, Charter Communications, Extended Stay Hotels and ION Media. He retired from the bench last month and will co-chair the MoFo group alongside partner Gary Lee.
