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.

In a move that would mark a significant departure from longstanding practice separating Department of Justice operations from direct White House control, the White House announced on January 8, 2026, a plan to create and directly supervise a new Department of Justice (DOJ) division for national fraud enforcement. The division would be led by a Senate-confirmed assistant attorney general (AAG). According to Vice President Vance, the new AAG will have “nationwide jurisdiction over the issue of fraud” and will be supervised by President Trump and Vice President Vance, rather than by DOJ leadership.

A class action is a procedural device that allows one or more persons, usually plaintiffs (though federal and state procedural rules also authorize defendant classes) to file suit on behalf of a group of similarly situated persons. Federal law defines a class action as “any civil action filed under Rule 23 of the Federal Rules of Civil Procedure or similar State statute or rule of judicial procedure authorizing an action to be brought by 1 or more representative persons as a class action.” 28 U.S.C. § 1332(d)(1)(B), (d)(8).

A privacy audit, also known as a privacy compliance audit, is an assessment tool that looks at an organization’s privacy protection policies and procedures, specifically in light of current relevant laws or regulatory requirements. The audits may be conducted by private organizations or by government agencies that are verifying a company’s regulatory compliance. In terms of privacy audit law, the FTC can conduct audits of organizations and take action when a company is improperly securing private information. Action is taken under the FTC Act, which covers unfair trade practices. Health Insurance Portability and Accountability Act audits are also conducted to ensure that providers are following HIPAA law and protecting private health information.
