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.

What Is Advertising Litigation?
Advertising litigation is defined as the legal area that covers false or deceptive advertising cases. Lawsuits may be brought by government agencies or corporate competitors based on the Lanham Act—a law that specifically deals with false advertising. The Act outlines how an advertisement can be deemed false. The Federal Trade Commission (FTC) has the ability to file lawsuits to halt deceptive advertising claims. The U.S. Food and Drug Administration may also pursue advertising litigation against violators of government regulations. Companies may be called on to substantiate their advertising claims, whether these are made in print or online.
