Read appellate briefs authored by Michael

Michael Kimberly is a partner in the Litigation & Dispute Resolution practice in Mayer Brown's Washington DC office. He briefs and argues complex appeals and dispositive motions with primary focus on the antitrust laws, environmental law, and constitutional law. He has argued eleven appeals in courts throughout the country, including the US Supreme Court, the Second, Sixth, Seventh, Eighth, and Ninth Circuits, and en banc sittings of the Second and Eleventh Circuits. He has written and filed over 100 briefs in the Supreme Court and all thirteen federal courts of appeals. Michael has been described by the Washington Post as a “seasoned Supreme Court practitioner” (2015), and according to Reuters (2014), Michael is among “a small cluster of specialists” and “the top handful of lawyers in America” who “dominate” the docket of the US Supreme Court.

Michael’s recent successes include representing the petitioners in Shapiro v. McManus, 136 S. Ct. 450 (2015), a redistricting case in which Michael’s briefing and argument resulted in a unanimous victory; the petitioner in France v. United States, 136 S. Ct. 583 (2015), a white collar criminal case in which Michael’s briefing persuaded the Solicitor General to confess error; and the petitioner in Georgia-Pacific West, Inc. v. Northwest Environmental Defense Center, 133 S. Ct. 1326 (2013), a Clean Water Act case in which the Court upheld a long-standing regulation concerning forest road runoff. Michael also obtained interlocutory appellate review and reversal of the denial of United’s motion to dismiss in the antitrust case, DPWN Holdings v. United Airlines, 747 F.3d 145 (2d Cir. 2014); and interlocutory appellate review and reversal of the denial of Siemens Corporation’s motion for summary judgment in the “hyper complicated” ERISA case, Shaver v. Siemens Corp., 670 F. 3d 462 (3d Cir. 2012).

Michael co-directs the Yale Law School Supreme Court Clinic, which regularly represents civil rights, immigrant, and criminal defense litigants before the Supreme Court. He also is an associate member of the Edward Coke Appellate Inn of Court and a regular participant in the Georgetown Supreme Court Institute.

A summa cum laude graduate of Princeton University, Michael received his JD from Yale Law School, where he served as Editor of The Yale Law Journal and Executive Editor of the Yale Law and Policy Review. Following law school, Michael clerked for Judge Michael Daly Hawkins on the US Court of Appeals for the Ninth Circuit.
