John Oldham McGinnis is a professor at Northwestern University School of Law and author of over 90 academic and popular articles and essays. His popular writings have been published in The Wall Street Journal, National Review, and Policy Review.
McGinnis teaches and writes on constitutional and international law. In constitutional law, he has focused especially on majority and supermajority rules. In international law, he has focused on the question of the proper role of international law in United States law.
McGinnis graduated from the Phillips Exeter Academy in 1975, and earned a B.A. from Harvard University in 1978, an M.A. from Balliol College, Oxford University in 1980, and a J.D. magna cum laude from Harvard in 1983. In 1997 he received the Paul M. Bator Award, which is awarded annually by the Federalist Society to an "outstanding legal scholar" under forty. McGinnis worked in the Office of Legal Counsel, Department of Justice from 1985 to 1991. He has given 10 testimonies before congress. McGinnis was also a litigation associate at the prestigious Sullivan & Cromwell, and a clerk on the United States Court of Appeals for the District of Columbia.
McGinnis's government posts are currently as a member of the National Advisory Committee for the North American Agreement on Labor Cooperation, and as a roster member of the United States Panelists for Resolution of World Trade Organization Disputes.
McGinnis is a co-author of a law review article stating that the majority of law school faculty members donate more to Democrats than to Republicans.  He uses this to attack the "viewpoint diversity" justification that the U.S. Supreme Court used to permit law schools to give racial minorities an advantage in their admissions processes. His argument is that law schools are not, and probably should not be, committed to political viewpoint diversity in the hiring process (implying that they should not use affirmative action-like techniques in recruiting and admitting students).
McGinnis has two books forthcoming. In Accelerating Democracy: Transforming Governance Through Technology (Princeton University Press, 2013) he argues that rapidly changing information technology can improve policy. In Originalism and the Good Constitution (Harvard University Press, 2013) he and Mike Rappaport contend that interpreting the Constitution according to its original meaning continues to have beneficial consequences today.
