Dan Jones is a partner in the Washington DC office and a member of the firm’s Consumer Litigation & Class Actions and Supreme Court & Appellate practices. Dan has authored numerous briefs in the US Supreme Court, federal and state appellate courts, and trial courts around the country, with a focus on arbitration and class action issues.  In 2020, Dan was selected by Law360 as a “Rising Star” in the field of appellate litigation—one of five lawyers to receive that recognition.   

Dan was part of the Mayer Brown team who represented the petitioner in Spokeo, Inc. v. Robins, in which the Supreme Court held that a lawsuit claiming a bare statutory violation—without allegations of concrete harm—does not satisfy Article III’s injury-in-fact requirement for standing to sue in federal court. Law360 called the Spokeo victory “a potent defensive tool” for businesses in naming Mayer Brown one of three firms of the year for 2016. Dan has authored numerous post­-Spokeo briefs urging lower courts to dismiss no-injury class actions under the Supreme Court’s ruling.

Dan has substantial experience litigating the enforceability of arbitration agreements—particularly in the consumer and employment contexts—at both the appellate and trial levels. Dan was a core part of the team that obtained victories for the petitioners in Lamps Plus, Inc. v. Varela and Kindred Nursing Centers LP v. Clark, two recent significant decisions from the Supreme Court interpreting the Federal Arbitration Act. Dan has also briefed many successful motions to compel arbitration in federal and state trial courts.

Dan also has substantial experience with critical motions seeking dismissal of class actions or opposing class certification. Dan has represented businesses in defeating class certification in multiple federal trial courts, and routinely briefs cutting-edge class action defense issues at both the trial and appellate levels.      

Prior to rejoining Mayer Brown in 2013, Dan clerked for the Honorable Stanley Marcus on the US Court of Appeals for the Eleventh Circuit. Dan graduated with honors from the University of Chicago Law School, where he served as the Executive Topics & Comments Editor on the University of Chicago Law Review. Dan received his BA from Amherst College, where he majored in English and mathematics.
