StubHub files lawsuit against Ticketmaster

StubHub is suing Ticketmaster and the Golden State Warriors, alleging it unfairly required fans looking to resell tickets to use Ticketmaster's resale exchange. Specifically, StubHub said Ticketmaster and the Warriors cancelled fans' regular-season and playoff-game tickets when those fans used StubHub and other exchanges to resell tickets. In other cases, the complaint says, Ticketmaster and the Warriors' front office broke the law by threatening fans with cancellation to force them to use Ticketmaster's resale exchange.
