The Ninth Circuit on Friday swiftly dispensed with an appeal seeking to revive a $54 million legal malpractice lawsuit against O’Melveny & Myers filed by a former client’s bankruptcy trustee.

The three-judge panel, having determined in late July that there was no need to hear oral arguments that had been scheduled for earlier this week, upheld a lower court ruling that plaintiff Jeffrey Golden could not relitigate the issue of legal fees charged by O’Melveny because an arbitrator had already found in favor of the firm.
