Michael Rayfield is a partner in Mayer Brown’s Supreme Court & Appellate practice. He focuses on class actions and other consolidated litigation, primarily in data privacy, product liability and securities lawsuits. He has argued cases in the Second Circuit, the Seventh Circuit, the Ninth Circuit, and a variety of federal and state trial courts, and has briefed state and federal appeals throughout the country. Mike has worked on over two dozen jury trials in all aspects of appellate preservation, including drafting and arguing motions in limine, directed-verdict motions and proposed jury instructions.

In 2019, Law360 named Mike as one of its “Rising Stars”—a list of “175 attorneys under 40 whose legal accomplishments transcend their age”—in the category of “Cybersecurity & Privacy,” explaining that Mike “has amassed victories for Facebook and other companies over a career that has also been marked by his dedication to pro bono work.” Among other things, Mike represents Facebook and Shutterfly in putative class actions alleging privacy violations under a state biometrics law, and recently argued a successful summary judgment motion in a lawsuit against Facebook. Mike is experienced in so-called “cookie” litigation—class actions challenging the use of cookies and other online tools to assist with targeted advertising. And Mike has briefed successful motions to dismiss securities class actions against Frontier Communications and Citibank.  

In addition to his work on behalf of corporate clients, Mike is devoted to representing individuals in criminal, immigration and civil rights appeals. Mike currently represents three clients convicted of murder or homicide offenses; several immigrants facing deportation from the United States; a man seeking to vacate his conviction under the federal drug “Kingpin Statute”; a woman seeking to hold several prison officials accountable for sexually assaulting her; and two men convicted of armed robbery offenses. Mike’s past victories include a decision by the Second Circuit reversing the conviction of a client convicted of murder for hire; two rulings by the Seventh and Ninth Circuits barring the government from deporting immigrants to Mexico and Honduras; and three decisions releasing clients from prison or ICE detention.

Prior to joining Mayer Brown in 2013, Mike was a law clerk to Judge Jay S. Bybee of the Ninth Circuit Court of Appeals, and to Judge Nicholas G. Garaufis of the Eastern District of New York. He also spent a year as a litigation associate at another prominent firm. Mike received his JD with high honors from the University of Chicago Law School, where he was a comments editor on the Law Review. He received his undergraduate degree from Cornell University.
