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

OCC Releases Preliminary Findings from Debanking Investigation

As Winston & Strawn has detailed in earlier articles and alerts, the Trump administration has prioritized addressing “politicized or unlawful debanking” (i.e., when financial institutions close or refuse to open customer accounts based on a customer’s political affiliation, religion, or involvement in legal but politically disfavored industries), using executive orders, agency bulletins, and internal investigative probes to tackle the subject. The administration’s actions are starting to produce measurable results.

Law Glossary

What Is a Class Action?

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)....Read more

What Is Removal Law?

Removal is a procedural mechanism through which a case filed in state court may be transferred to federal court upon the request of one or more parties. Actions filed in state court over which a federal court would have original jurisdiction may be transferred—or removed—to federal court under the removal statute, 28 U.S.C. § 1441. Generally speaking, removal is possible if (1) the plaintiff(s) and defendant(s) are citizens of different states and the case places more than $75,000 in controversy (so-called “diversity” jurisdiction), or (2) the case turns on issues of federal law (so-called “federal question” jurisdiction). In many cases, defendants prefer to be in federal court, and so defendants often analyze early in the case whether removal is possible. ...Read more

What Are Dark Patterns?

Dark patterns are deceptive or manipulative designs on digital platforms that trick users into making unintended choices. Dark patterns can appear as designs that create misleading impressions, hide or delay disclosure of material information, lead to unauthorized charges, or obscure privacy choices. Some examples include advertisements deceptively formatted to look like independent editorial content; non-descriptive dropdowns, arrows, or small icons to hide the full cost and other terms, free trials that automatically convert to recurring subscriptions; and prominent cookie-consent banners that hide cookie-rejection options....Read more
