Winston Secures Transformative Antitrust Verdict for States in Live Nation and Ticketmaster Trial
A Winston & Strawn team, led by Jeffrey Kessler, secured an antitrust verdict on behalf of more than 30 states and the District of Columbia, with a Manhattan federal jury finding Live Nation Entertainment and Ticketmaster liable for violating federal and state antitrust laws in a decision that has the potential to transform the concert, music, and ticketing industry. The jury concluded that Ticketmaster unlawfully maintained a monopoly in the primary ticketing market for major concert venues and that Live Nation unlawfully monopolized the large amphitheater market, compelling artists to use its promotion services to access its venues. Jurors further found that this conduct resulted in higher ticket fees, leading to an approximate $1.72 overcharge per ticket for consumers.

In the United States, the Internal Revenue Service (IRS) is the federal tax authority. Most states, territories, and local jurisdictions also have tax authorities to ensure compliance with applicable state and local laws and regulations. These tax authorities are generally responsible for collecting taxes, administering tax laws, and enforcing tax compliance in their respective jurisdictions.
