End of the Line: Winston Wins Unanimous Supreme Court Victory Against NJ Transit
In a unanimous decision authored by Justice Sotomayor, the U.S. Supreme Court held that NJ Transit is not an arm of the State of New Jersey and therefore is not entitled to sovereign immunity. The ruling means that plaintiffs injured by NJ Transit outside of New Jersey—such as in Pennsylvania and New York—may pursue claims in the courts of the states where their injuries occurred. The court adopted Winston’s position that state-created corporations that are formally liable for their own judgments are not arms of the state, reversing the Pennsylvania Supreme Court’s dismissal of Cedric Galette’s negligence suit while affirming the New York Court of Appeals’ decision allowing Jeffrey Colt’s case to proceed.

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.

What Are Interchangeable Biological Products?
A biological product is interchangeable if it is biosimilar to the reference product and is expected to produce the same clinical result as the reference product in any given patient. A biosimilar product that is deemed to be interchangeable by the FDA means the biosimilar product can be substituted for the reference product by a pharmacist without consulting the prescriber. The specific requirements for substitution vary by state.
