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.
