Weil, Gotshal & Manges continues to make it rain in the largest bankruptcy case in U.S. history. The firm has served as lead counsel to Lehman Brothers since the start of its bankruptcy case in September 2008, a role that has translated into more than $300 million in fees and expenses for Weil.

According to Lehman’s monthly operating report for June, the bankrupt investment bank spent another $27.5 million on professional fees last month, bringing the total spent on outside advisers by the debtor to $1.35 billion.
