Michael Rayfield is a partner in Mayer Brown’s Supreme Court & Appellate practice. He specializes in high-stakes class actions and other consolidated litigation, primarily in 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 various 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.

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 also has particular expertise in so-called “cookie” litigation—cases challenging the use of cookies and other online tools to assist with targeted advertising, and alleging violations of the Wiretap Act, the Stored Communications Act, the California Invasion of Privacy Act, and various common-law doctrines.

In addition to representing corporate clients, Mike has an active practice in criminal and immigration law. Mike currently represents two clients previously convicted of murder-for-hire, and recently argued and won an appeal in the Second Circuit reversing the conviction of one of those clients. Mike has successfully represented a Mexican immigrant seeking relief from deportation in the Seventh Circuit, and is now handling two appeals in the Ninth Circuit on behalf of immigrants facing deportation.

Prior to joining Mayer Brown in 2013, Mike worked as 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 international law firm based in New York. 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.
