Mayer Brown Rowe & Maw could face legal action after a court examiner in the Refco bankruptcy case said evidence had been found that the firm had committed professional negligence and fraud.

Creditors of Refco – the futures broker that filed for bankruptcy in 2005 – were told they had a strong case against the Chicago-based law firm after a court examiner found “sufficient evidence” to bring a claim against the firm for “aiding and abetting a breach of fiduciary duty and fraud”.
