Jason Mazzone is the Albert E. Jenner, Jr. Professor of Law at the University of Illinois at Urbana-Champaign and Director of the Illinois Program in Constitutional Theory, History, and Law. 

Professor Mazzone’s primary field of research and teaching is constitutional law and history. He works principally on issues of constitutional structure and institutional design with a particular focus on relationships between structural arrangements and individual rights. His groundbreaking work on the Constitution of the United States has appeared in dozens of prominent legal journals. He regularly advises, on a pro bono basis, litigants in cases before the Supreme Court of the United States and in other courts. A good part of Professor Mazzone’s research involves comparative issues in constitutional law. He has lectured around the world on this topic and he has advised new democracies during their processes of drafting and implementing their own constitutions. Unifying all of this work is a close attention to the role of culture in grounding and shaping formal constitutions, a topic Professor Mazzone first explored in his dissertation at Yale University. Professor Mazzone is currently at work on two books: one a global study of the future of constitutional rights; the other, a study of how the U.S. Constitution serves as both a unifying and dividing force in American society. 

Professor Mazzone works also in the field of intellectual property law. He is the world’s leading expert on overreaching assertions of intellectual property rights. In a famous article published in the NYU Law Review in 2006, Professor Mazzone coined the term, “copyfraud,” to describe claims of copyright in works that are actually in the public domain and cannot be copyrighted by anyone. That article generated scores of studies by other academic researchers and “copyfraud” became the tagline for popular criticism of excessive intellectual property claims. Professor Mazzone’s acclaimed book, Copyfraud and Other Abuses of Intellectual Property Law, was published in 2011 by Stanford University Press. Professor Mazzone’s work on overreaching intellectual property claims has produced legislative reforms in France and other countries; provided the framework for high-profile lawsuits to limit intellectual property rights to their statutorily-designated scope; inspired symposia and conferences at home and abroad; shaped the work of public interest organizations and legal clinics devoted to protecting the public domain; provided guidance to the work of the U.S. Copyright Office and the U.K. Intellectual Property Office; and served as a framework for rethinking key aspects of our system of intellectual property laws. 

Professor Mazzone received his undergraduate and law degrees from Harvard University, a master’s degree from Stanford University, and a master’s and doctorate from Yale University. While a student he worked with Laurence H. Tribe on constitutional cases in the Supreme Court and for Robert D. Putnam on the bestselling book Bowling Alone: The Collapse and Revival of American Community. He served also as Rapporteur to the Saguaro Seminar on Civic Engagement in America, a workshop group whose members included then-Illinois State Senator Barack Obama. Before entering law teaching, Professor Mazzone clerked for Judge Robert D. Sack of the U.S. Court of Appeals for the Second Circuit and for Judge John G. Koeltl of the U.S. District Court for the Southern District of New York, and he practiced intellectual property law in New York City. 

Professor Mazzone is a member of the American Law Institute and a fellow of the European Law Institute. He is Chair of the Illinois-Bologna Conference on Comparative Constitutional History, a member of the Advisory Board of the Italian Law Journal, and a member of the International Association of Constitutional Law Research Group on Constitutionalism in Illiberal Democracies. He has also served on the Board of Trustees of the Copyright Society of the USA. His scholarship has been cited by many courts, including the Supreme Court of the United States. He is a regular media commentator and he has written about legal issues for The New York Times and other national newspapers. Professor Mazzone blogs at Balkinization.

Illinois Law dean Vikram David Amar and professor Jason Mazzone consider some possible explanations for the ever-decreasing number of applicants for tenured/tenure-track faculty among law schools. Dean Amar and Professor Mazzone propose five possible reasons but point out that whatever the true reason(s), the apparent decline in the demand among talented new legal minds for law-teaching jobs should be a topic of discussion and concern.

Illinois Law dean Vikram David Amar and professor Jason Mazzone respond to several points about originalism made by Berkeley Law Dean Erwin Chemerinsky in a recent article published in The Atlantic. Dean Amar and Professor Mazzone explain why three claims in particular—that originalism is an “obscure legal theory” only a few decades old, that judicial review in the federal courts is anti-originalist, and that accurately determining original meaning is “impossible.”

Illinois Law dean Vikram David Amar and professor Jason Mazzone respond to a recent column by New York Times columnist David Leonhardt, arguing that neither of the recent high-profile developments after the Dobbs v. Jackson Women’s Health Organization decision is an example of “defying” the Court or “checking” judicial power. Dean Amar and Professor Mazzone point out that while neither the abortion vote in Kansas nor the pending federal marriage-equality proposal may fairly be characterized as “defying” or “checking,” some political reactions to Supreme Court rulings in the past arguably have involved defiance or disobedience of the Court.

In this second of a series of columns, Illinois Law dean Vikram David Amar and professor Jason Mazzone describe the facts and law giving rise to Berger v. North Carolina State Conference of the NAACP, a North Carolina voter ID case pending before the U.S. Supreme Court. Dean Amar and Professor Mazzone argue that the case highlights the importance of the legal procedure of certification and suggest that if the Court’s decision falls back on the traditional model of singular executive-branch representation embraced by the federal system and that of other states, the North Carolina legislature will have only itself to blame.

In this first of a series of columns, Illinois Law dean Vikram David Amar and professor Jason Mazzone describe the development of the legal procedure of certification of state-law questions—by which federal courts ask a state high court how state law would apply to specific circumstances. Dean Amar and Professor Mazzone explain why this procedure may be particularly helpful in a case currently pending in the U.S. Supreme Court, Berger v. North Carolina State Conference of the NAACP, which shows the downsides to a state’s (North Carolina’s0 unique refusal to accept certified questions.

Illinois Law dean Vikram David Amar and professor Jason Mazzone comment on a recent case from Virginia that suggests when revising admissions criteria to alter the racial makeup of a school’s student body is constitutional (and when it is not). Dean Amar and Professor Mazzone point out that although some Supreme Court Justices have suggested in dicta and dissents some permissible options, they may very well decide that those options too are impermissible, despite the natural and reasonable reliance on those writings.

Illinois Law dean Vikram David Amar and professor Jason Mazzone explain why a recent ruling by the U.S. Court of Appeals for the Fifth Circuit egregiously misunderstands the Commerce Clause issues presented in several lawsuits challenging the federal Occupational Safety and Health Administration (OSHA)’s authority to mandate vaccine and testing requirements for large employers. Dean Amar and Professor Mazzone focus on three ways in which the Fifth Circuit gets it wrong and expresses hope that the Sixth Circuit, which is where the lawsuits have been consolidated, does better.

Dean Amar and Professor Mazzone point out that lawyers and judges are steeped in factual investigation and factual determination, and they call upon legal educators (like themselves) to continue instilling in students the commitment to analytical reasoning based in factual evidence, and to absolutely reject the notion that factual truth is just in the mind of the beholder.
