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.

Columns by Jason Mazzone
Why Is an Election Law Challenge (Brought by Republicans Against Governor Whitmer Concerning Voter Registration Centers) That Is Grounded in Michigan State Law Proceeding in Federal Court—and What Are the Lawyers Doing There?

UC Davis Law professor Vikram David Amar and Illinois Law professor Jason Mazzone analyze a recent election-related lawsuit filed in Michigan federal court, critiquing the legal arguments and the court’s handling of the case in the context of federal jurisdiction principles. Professors Amar and Mazzone argue that the lawsuit clearly lacks federal subject-matter jurisdiction and should have been promptly dismissed, highlighting this case as an example of poor lawyering and judicial oversight that is unnecessarily complicating the legal landscape ahead of the upcoming election.

Observations on Last Week’s Fifth Circuit Oral Argument in a Mississippi Case Involving the Counting of Ballots That Are Cast Before Election Day but that Arrive by Mail to Election Offices A Few Days After Polls Close

UC Davis Law professor Vikram David Amar and Illinois Law professor Jason Mazzone discuss a legal challenge to Mississippi’s law allowing the counting of absentee ballots that arrive up to five business days after Election Day, as long as they are postmarked by Election Day. Professors Amar and Mazzone argue that the law is consistent with federal election statutes and constitutional principles, and that the plaintiffs’ interpretation of “Election Day” is overly narrow and inconsistent with other accepted election practices.

With the End of Its 2023-24 Term in Sight, the Supreme Court Has Not Been Particularly Partisan or Aggressive This Year, Even as it Has Had No Choice but to Take Certain High-Profile Cases (In Part Because of an Out-of-step Lower Court, the Fifth Circuit Court of Appeals)

UC Davis Law professor Vikram David Amar and Illinois Law professor Jason Mazzone examine the current term of the U.S. Supreme Court, addressing common criticisms that the Court has become a partisan, far-right institution aggressively pushing a conservative agenda. Professors Amar and Mazzone argue that, contrary to these criticisms, the Court’s decisions in the 2023-24 term have not been consistently conservative or partisan, and that many of the high-profile cases were essentially thrust upon the Court rather than actively sought out, suggesting a more nuanced and less ideologically driven approach than critics claim.

Can a Public High School Punish a Student for Asking a Question that Refers to “Illegal Aliens”? Part Two in a Two-Part Series

In this second of a two-part series of columns discussing a recent incident at a North Carolina high school where a student was suspended for using the term “illegal alien” in class, UC Davis Law professor Vikram David Amar and Illinois Law professor Jason Mazzone explore how the dispute might be analyzed applying only the Supreme Court’s seminal decision in Tinker v. Des Moines Independent School District. Professors Amar and Mazzone argue that while schools have some authority to regulate disruptive student speech under Tinker and Hazelwood v. Kuhlmeier, the student’s suspension here likely violated due process because he lacked clear prior notice that using this term, which appears in Supreme Court opinions and federal statutes, was prohibited.

Can a Public High School Punish a Student for Asking a Question that Refers to “Illegal Aliens”? Part One in a Two-Part Series

In this first of a two-part series of columns discussing a recent incident at a North Carolina high school where a student was suspended for using the term “illegal alien” in class, UC Davis Law professor Vikram David Amar and Illinois Law professor Jason Mazzone explain the relevant First Amendment case law surrounding student speech in public K-12 schools. Professors Amar and Mazzone suggest that under the Supreme Court’s decision in Hazelwood School District v. Kuhlmeier, which allows schools broad authority to regulate student speech that occurs within the curriculum, the school may have been justified in disciplining the student, but they note that there are still some unresolved questions and complexities that they will address in Part II of their analysis.

The Supreme Court’s Misplaced Emphasis on Uniformity in Trump v. Anderson (and Bush v. Gore)

UC Davis Law professor Vikram David Amar and Illinois Law professor Jason Mazzone coment on the U.S. Supreme Court’s recent ruling in Trump v. Anderson holding that states cannot enforce Section 3 of the Fourteenth Amendment to bar former President Donald Trump from primary election ballots due to his alleged role in the January 6 Capitol breach. Professors Amar and Mazzone argue that the Court’s reasoning, primarily based on concerns about nationwide ballot uniformity in presidential elections, is flawed because it fails to properly consider the Constitution’s overall design, which grants states significant autonomy in running presidential elections and selecting electors.

Was the Federal District Court Correct in Dismissing Disney’s Speech-Retaliation Case Against Florida Officials?

UC Davis Law professor Vikram David Amar, Illinois Law professor Jason Mazzone, and Illinois Law’s First Amendment Clinic director Lena Shapiro examine the legal intricacies and constitutional debates surrounding a federal district court’s dismissal of the Disney Corporation’s lawsuit against Florida officials, in which Disney alleges retaliatory action for Disney’s criticism of Florida laws by changing the governance of the land regulating Disney World. The authors highlight the complexity of First Amendment issues involved, the precedent set by prior cases, and the broader implications for speech regulation and governmental retaliation, suggesting areas for deeper academic exploration.

Why a Recent Federal Lawsuit Filed by Republican Party Officials Challenging Mississippi’s Approach to Counting Ballots in Federal Elections Lacks Any Significant Chance of Success

UC Davis Law professor Vikram David Amar and Illinois Law professor Jason Mazzone comment on a federal lawsuit filed by the Republican National Committee and the Republican Party of Mississippi, among others, challenging Mississippi’s law that counts mail-in ballots postmarked by Election Day but received within five business days thereafter for federal elections. Professors Amar and Mazzone argue that this lawsuit is unlikely to succeed due to the implausibility of its legal theory, highlighting the distinction between the act of voting and the counting of votes, and underscoring the constitutional and statutory framework that grants states broad leeway in election administration, including the acceptance of mail-in ballots.

Another Free-Speech Dustup Arising from A Student-Invited-Speaker Event, This One at Pitt, Highlights Recurring Problems at Universities, and in Free Speech Doctrine

Illinois Law dean Vikram David Amar and professor Jason Mazzone comment on another free-speech controversy related to a student-invited speaker at the University of Pittsburgh. Dean Amar and Professor Mazzone describe the demand letter sent to Pitt officials by the Alliance Defending Freedom and explain why some of their arguments are on solid legal ground while one is tenuous at best.

Fourth Circuit High School Case from Virginia Offers Controversial, and Seemingly Dubious, Definition of “Disparate Impact” in Equal Protection Challenges

Illinois Law dean Vikram David Amar and professor Jason Mazzone comment on a recent decision by the U.S. Court of Appeals for the Fourth Circuit involving the admissions policy at a school in Virginia. Dean Amar and Professor Mazzone argue that while it’s not clear whether the U.S. Supreme Court will review this case, the issue the case raises is likely to be one the Court takes up soon.

The Court Should Maintain Optionality in Resolving the So-Called “Independent State Legislature” (ISL) Theory by Granting Cert. in Huffman v. Neiman Right Away as the Justices Chew on Whether Moore v. Harper is Moot

Illinois Law Dean Vikram David Amar and Professor Jason Mazzone argue that, in light of the North Carolina Supreme Court’s “switcheroo” regarding partisan gerrymandering, the U.S. Supreme Court should immediately grant certiorari in Huffman v. Neiman to resolve the question of “Independent State Legislature (ISL) theory. Dean Amar and Professor Mazzone point out that the intense litigation pressure of today’s presidential elections and the shaky stature of the present Supreme Court together strongly support the Court acting quickly to resolve this pressing issue.

Friendly Advice for Law Schools Seeking to Inculcate Proper Free-Speech Values and Understandings in Light of the Stanford Episode with Judge Kyle Duncan: Part Two in a Series

In this second of a series of columns in response to the Stanford Law School controversy involving disruption of a federal judge’s speech, Illinois Law dean Vikram David Amar and professor Jason Mazzone offer additional thoughts about how to design a training session about the freedom of speech and norms of the legal profession should include. Specifically, Dean Amar and Professor Mazzone discuss (1) when and how educational institutions should themselves speak, (2) the best ways to register disagreement with offensive speakers and messages, and (3) what schools should do about students who say they feel genuinely harmed or unsafe when certain kinds of speakers are present.

What Law Students Should Take Away from the Stanford Law School Controversy Involving Disruption of a Federal Judge’s Speech: Part One in a Series

In response to the Stanford Law School controversy involving disruption of a federal judge’s speech, Illinois Law dean Vikram David Amar and professor Jason Mazzone offer thoughts about how to design a training session about the freedom of speech and norms of the legal profession should include. In this first of a series of columns, Dean Amar and Professor Mazzone focus on two key topics: (1) What, precisely is “shouting down” of a speaker, and why can such activity be prohibited and punished? And (2) What About the Venerable Tradition of “Civil Disobedience”?

Vacancy-Filling Wrinkles Created by Ben Sasse’s Expected Departure from the U.S. Senate

Dean Amar, Professor Mazzone, and Mr. Yan describe the requirements and constraints of Nebraska state law and the U.S. Constitution.

Is Justice Kagan Right that Areas of Constitutional Law Should Not Change Quickly on Account of New Membership on the Court?

Illinois Law dean Vikram David Amar and professor Jason Mazzone comment on recent comments by U.S. Supreme Court Justice Elena Kagan expressing reservations about doctrinal changes attributable to the arrival of new Justices. Dean Amar and Professor Mazzone argue that new Justices have played an important and generally positive role in advancing the constitutional landscape.

Where Have All the (Aspiring) Law Profs Gone?

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.

If Originalism Is Going to Be Displaced, Critics Must Do Better than Dean Chemerinsky Seems to Be Doing

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.”

What Does it Mean for Other Institutions to “Defy” or “Check” the Supreme Court? Not What the Court Invites Those Institutions to Do

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.
