Michael Rayfield is a partner in Mayer Brown’s Supreme Court & Appellate practice. He focuses on high-stakes 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.

Mike has deep experience opposing class certification and developing overarching trial plans—filings outlining the best approach for defendants to litigate individualized issues after a class has been certified. 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 also experienced in so-called “cookie” litigation—class actions challenging the use of cookies and other online tools to assist with targeted advertising.

In addition to his work on behalf of corporate clients, Mike is devoted to representing individuals in high-stakes criminal, immigration, and civil rights appeals. Mike currently represents three clients convicted of murder or homicide offenses; two immigrants facing deportation from the United States; a man seeking to vacate his conviction under the federal drug “Kingpin Statute”; and a woman seeking to hold several prison guards accountable for sexually assaulting her. In the past, Mike has won an appeal in the Second Circuit reversing the conviction of a client convicted of murder for hire, and an appeal in the Seventh Circuit on behalf of a Mexican immigrant seeking relief from deportation.

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.
