Winston Wins Ninth Circuit Reversal and Class Certification in Swimmers’ Antitrust Case, Securing a Global-Impact Settlement with World Aquatics

Winston represents a class of professional swimmers alleging World Aquatics (WA) violated antitrust laws by blocking their participation in the competing  International Swimming League. After WA won summary judgment, Winston successfully appealed, arguing the court applied improper antitrust standards and wrongly denied certification of a damages class. In September 2024, the Ninth Circuit reversed both rulings, reviving all claims and issuing a landmark ruling on the possible application of the per se rule or quick look review to sports-associations rules. Am Law awarded Winston “Litigator of the Week” Runner-Up recognition for the win. In November 2024, the Ninth Circuit denied rehearing. In April 2025, the district court certified a damages class....Read more

SEC to Companies: You’re on Your Own (Sort Of) Under Rule 14a-8

On November 17, 2025, the staff (the Staff) of the Securities and Exchange Commission’s (SEC) Division of Corporation Finance (the Division) announced a significant shift in its approach to the shareholder proposal process for the upcoming 2025-2026 proxy season. The Staff will no longer respond to most no-action requests under Exchange Act Rule 14a-8, which permits qualifying shareholders to place proposals in a public company’s proxy materials, while allowing issuers to omit proposals that fall within the rule’s procedural or substantive exclusions. Rule 14a-8 is a longstanding point of contention between issuers and proponents of socially and operationally significant shareholder proposals. This guidance fundamentally alters how the Division will address exclusion requests and increases uncertainty for issuers preparing proxy materials.
