A New York federal judge is urging over two dozen states to settle their antitrust claims against Ticketmaster and its parent company this week after the Justice Department reached a deal and dropped out of an ongoing trial. Dan Wall, a lawyer for Ticketmaster parent Live Nation Entertainment, told Judge Arun Subramanian on Tuesday there was no chance all states would quickly settle. He said he based his assessment on the nature of discussions between the ticketing and entertainment giants and the states over the past week. Still, the judge persuaded lawyers for both sides to negotiate in Manhattan federal court.
