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 a Non-Fungible Token (NFT)?
The definition of a Non-Fungible Token, also known as an NFT, is a digital certificate (or token) which is stored on decentralized ledgers popularly referred to as the blockchain. NFTs use software code, referred to as “smart contracts,” to transfer the digital certificate of ownership, ensuring proof of ownership in the process. Like cryptocurrency, NFTs also use the blockchain to record transactions, but where cryptocurrency creates interchangeable (or “fungible”) tokens, NFTs create unique, noninterchangeable tokens with distinct identifiers.
