John Nadolenco

Partner, Mayer Brown

John Nadolenco’s civil litigation practice focuses on high-stakes cases and class action defense, including defending consumer class actions, and employment and antitrust cases. Mr. Nadolenco is handling several high-profile cases. He has been lead counsel in Spokeo, Inc. v. Robins, which the United States Supreme Court decided in our client’s favor, making it harder for plaintiffs to bring no-injury lawsuits. Some said the case implicated “the future of consumer class actions” because the case raised whether simply alleging the violation of a statute was sufficient to confer Article III standing, as many plaintiffs in Internet privacy, cybersecurity and numerous other types of cases allege. Indeed, Mr. Nadolenco has spent much of his career developing creative defenses used to defeat class actions.

Along those lines, Mr. Nadolenco recently represented Facebook in several cases alleging privacy violations under a state biometrics law. He also defended Volkswagen in dozens of putative class actions alleging the company improperly installed emissions-defeat devices on some of its diesel cars. And Mr. Nadolenco represents the Country of Brazil in its effort to capture the infamous 840-pound Bahia Emerald. Mr. Nadolenco’s efforts in that case have made international and national headlines. 

More particularly, Mr. Nadolenco has defended companies in cases alleging improper consumer charges and practices, false and misleading advertising, defective products, unauthorized call recording under California’s Invasion of Privacy Act (CIPA), violations of the Fair Credit Reporting Act (FCRA), Internet privacy violations and improper tracking via computer-based cookies and improper use of smartphone and tablet applications (apps). Mr. Nadolenco has extensive experience defending wage-hour cases, including cases alleging meal-period, rest-period and off-the-clock violations, as well as claims alleging incorrect pay statements and waiting-time and other penalties. Mr. Nadolenco also has extensive experience drafting and enforcing consumer and employee arbitration provisions, privacy policies, terms of use and social-media policies. Mr. Nadolenco served as co-editor of Mayer Brown’s The Social Media Revolution: A Legal Handbook.

Mr. Nadolenco is a member of Mayer Brown’s Partnership Board and also a firm-wide co-lead of the Litigation & Dispute Resolution practice. He previously served as the Los Angeles office practice leader for the litigation practice and firm-wide co-lead of the Consumer Litigation & Class Actions practice. He received a Martindale-Hubbell peer review rating of AV-Preeminent in 2013 and was also named in the 2010 and 2011 editions of The Best Lawyers in America.® In 2009, he was named one of the “Top 20 California Lawyers Under 40” by the Daily Journal. Mr. Nadolenco joined the firm in 1995. 

Mr. Nadolenco received his JD summa cum laude from the American University Washington College of Law and his BA summa cum laude from the University of Arizona.
