After beating back legal malpractice claims, O’Melveny & Myers is now looking to dismiss the rest of a $54 million lawsuit brought by a bankruptcy trustee.

The law firm on Monday petitioned a California federal judge to dismiss the remaining claims of trustee Jeffrey Golden, who has alleged the firm fraudulently transferred millions of dollars out of client Aletheia Research and Management for legal fees just before it filed Chapter 7 liquidation papers.
