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.

“Baby HSR” or “mini HSR” laws refer to state-level premerger notification and reporting requirements that resemble the federal Hart-Scott-Rodino Act but tend to apply to smaller transactions valued below the federal notification thresholds. These laws, often focused on specific industries like healthcare, aim to enhance state-level antitrust oversight by requiring companies to notify state authorities of mergers or acquisitions that could impact local competition. Filing obligations, timing, and fees vary by state, with some requiring detailed disclosures about the transaction’s competitive impact within the state. State authorities can investigate, challenge, or impose conditions on transactions even if they are cleared federally. Winston’s Baby HSR survey provides buyers and sellers with a resource to quickly start assessing which states may have premerger notification requirements that impact their transactions.
