As Mayer, Brown, Rowe & Maw readies for potential claims arising out of its representation of failed commodities brokerage Refco, the Chicago law firm’s work for another bankrupt company has already triggered a $17 million suit against it.

The bankruptcy trustee for defunct health care management company CMGT Inc. has sued its former lawyers at Mayer Brown for failing to challenge lawsuits brought against the company by its former financial adviser, Gerry Spehar. According to the trustee, the unopposed litigation crippled the company and handed Spehar a $17 million default judgment.
