Ticketmaster and its parent company, Live Nation, are asking a U.S. court to throw out the verdict and order a new trial in a landmark anti-trust case where a jury found the company operates an anti-competitive monopoly that’s been overcharging sports and music fans.

This latest legal salvo comes just hours after 33 states alongside the District of Columbia filed formal motions on Thursday calling for the breakup of the world’s largest entertainment conglomerate.

The plaintiff states are asking the U.S. District Court of Southern New York to order compensation for fans, stricter industry controls and the selloff of amphitheatres as well as Ticketmaster, Live Nation’s online box office arm.
