A litigator with three decades of experience, Sonya Winner handles high-stakes civil cases for clients in a wide range of industries, including banking, pharmaceuticals and professional sports. She has handled numerous antitrust and consumer disputes, many of them class actions, in state and federal courts across the country.

Sonya’s cases typically involve difficult technical issues and/or complex legal and regulatory schemes. She is regularly able to resolve cases before the trial phase, often through dispositive motions. But when neither summary judgment nor a favorable settlement is an option, she has the confidence of her clients to take the case all the way through trial and on appeal. Her recent successes have included a cutting-edge decision rejecting a “true lender” challenge to National Bank Act preemption in a class action involving interest rates on student loans, as well as the outright dismissal of a putative antitrust claim against the National Football League and its member clubs asserting an unlawful conspiracy to fix cheerleader compensation.

Sonya has been recognized as a leading trial lawyer by publications like Chambers and the Daily Journal. She is chair of the firm’s Class Action Litigation Practice Group.

The Sixth Circuit recently vacated a class certification order in a decision that may make it easier for defendants to defeat putative class actions where a named plaintiff asserts standing based on the injuries of absent class members.  Under the “juridical link doctrine,” a named plaintiff may bring a class action against defendants who did not injure them so long as the absent members of the proposed class would have standing to sue those defendants.  In vacating a district court order that certified a class based on this doctrine, the Sixth Circuit joined the Second Circuit in rejecting the doctrine and holding that named plaintiffs in a putative class action must have standing to sue every defendant at the time of filing.…

Another court in the Eastern District of Michigan recently dismissed a putative class action on prudential mootness grounds, holding that the manufacturer’s voluntary recall program—which was supervised by a federal administrative agency—mooted the plaintiffs’ consumer fraud and warranty claims.  See Pacheco v. Ford Motor Co., 2023 WL 2603937 (E.D. Mich. Mar. 22, 2023).…

            The Ninth Circuit continues its efforts to give teeth to the predominance requirement of Rule 23 as a potent tool for defendants to defeat class certification. 

            Earlier this year, in Bowerman v. Field Asset Services, Inc., 39 F.4th 652 (9th Cir. 2022), amended, — F.4th —-, 2023 WL 2001967 (9th Cir. Feb. 14, 2023), the Ninth Circuit determined that where individualized inquiries were necessary to determine the existence of damages—as opposed to the question of calculating damages—class certification was inappropriate because the class would fail to meet the predominance requirement of Rule 23. …

In two putative class actions pending in the Eastern District of North Carolina, the Department of Justice has filed statements of interest urging the Court to deny defendants’ motions to compel arbitration of plaintiffs’ claims for violations of the Servicemembers Civil Relief Act.

A procedural violation of a state’s privacy statute is not alone enough to establish Article III standing—a plaintiff must suffer a concrete injury, such as an increased risk of identity theft.  The Fourth Circuit’s decision in O’Leary v. TrustedID, Inc., 2023 WL 2125996 (4th Cir. Feb. 21, 2023) confirms this—but also illustrates how Article III standing is a two-edged sword that may allow a plaintiff to defeat a defendant’s attempt to remove a case to federal court. 

The plaintiff in O’Leary filed a class action against TrustedID in South Carolina state court for allegedly violating South Carolina’s Financial Identity Fraud and Identity Theft Protection Act, S.C. Code Ann. § 37-20-180.  The statute prohibits requiring consumers to use six or more digits of their Social Security numbers to access a website without also requiring some other authentication measure.  The plaintiff alleged that TrustedID’s website required him to provide six digits of his Social Security number and did not have any other safety precautions, such as a password requirement.…

The Ninth Circuit recently held in Chamber of Commerce v. Bonta that the Federal Arbitration Act preempts a California law that criminalizes employer conduct that requires employees to consent to arbitrate claims arising under the California Fair Employment and Housing Act.  This ruling came after the same panel previously held that the law, Assembly Bill 51, was not preempted because it focused on “pre-agreement” behavior and not the arbitration agreement itself.  In 2021, the panel sua sponte decided to rehear the case, apparently after Judge Fletcher (who was in the majority in both decisions) changed his mind on the law’s validity.  In doing so, the panel eliminated a circuit split it had previously created between itself and the First and Fourth Circuits.…

In a one-line order issued last week, the Supreme Court dismissed In Re Grand Jury, No. 21-1397, one of the most significant cases about the attorney-client privilege in decades.  The dismissal came just two weeks after oral argument.  The Court explained that the writ of certiorari had been “improvidently granted,” meaning the Court should…

Under the Ninth Circuit’s 2020 decision in Sonner v. Premier Nutrition Corp., 971 F.3d 834 (9th Cir. 2020), plaintiffs cannot recover equitable relief in federal court if they have an adequate legal remedy.  More than two years later, district courts remain divided on how to apply Sonner at the pleading stage, with some postponing the analysis to later stages and others routinely dismissing equitable claims.  In courts that take the stricter view, Sonner can be a useful tool for narrowing the claims class action defendants must litigate in a federal case, particularly in California, where common consumer protection claims are largely limited to equitable remedies.  That said, a pair of recent Ninth Circuit decisions highlights that defendants should carefully consider the risk that a plaintiff will refile dismissed equitable claims in state court.…

The Supreme Court recently granted certiorari in a case to resolve a circuit split that has serious implications for companies who are unsuccessful in their efforts to enforce arbitration provisions in federal district courts. 

In Coinbase, Inc. v. Bielski, No. 22-105, the defendant moved to compel arbitration in two putative class actions.  The motions to compel were denied, and the defendant sought stays while it appealed the denials—which the Federal Arbitration Act gives defendants an automatic right to do.  See 9 U.S.C. § 16.  Both motions to stay were denied, and the Ninth Circuit affirmed both decisions.…

We previously wrote about the rising trend of mass arbitration and how companies and arbitration providers have responded to it thus far, including by adopting new rules and contract terms specifically geared towards coordinated proceedings.  It may be tempting to impose strict controls on how mass arbitrations can proceed.  But in considering their options, companies…
