A Manhattan federal judge has denied again CVR Energy’s attempts to pursue a legal malpractice case against Wachtell, Lipton, Rosen & Katz, writing that the central allegation in CVR’s case boiled down to “mere accusations of an error in judgment.”

Still, CVR attorney Herbert Beigel vowed to continue fighting. “In view of the previous rulings by the court, I can’t say I’m surprised by it,” he said in a brief interview Friday. “We’re looking forward to an appeal to the Second Circuit.”
