  • “Worldwide Tally” of Legal Decisions Involving AI Hallucinations

    Damien Charlotin, from Science Po Law School and HEC Paris, has “a database [that] tracks legal decisions in cases where generative AI produced hallucinated content – typically fake citations, but also other types of AI-generated arguments.” You can find the database at this link. The database was recently highlighted in a story by NPR.

    Last year saw a rapid increase in court sanctions against attorneys for filing briefs containing errors generated by artificial intelligence tools. The most prominent case was that of the lawyers for MyPillow CEO Mike Lindell, who were fined $3,000 each for filing briefs containing fictitious, AI-generated citations. But as a cautionary tale, it doesn’t seem to have had much effect.

    “Recently we had 10 cases from 10 different courts on a single day,” says Damien Charlotin, a researcher at the business school HEC Paris who keeps a worldwide tally of instances of courts sanctioning people for using erroneous information generated by AI.

    The numbers started taking off last year, and Charlotin says the rate is still increasing. He counts a total of more than 1,200 to date, of which about 800 are from U.S. courts. Penalties are also on the rise, he says. A federal court may have set a record last month with an order for a lawyer in Oregon to pay $109,700 in sanctions and costs for filing AI-generated errors.

  • Holden and Kisska-Schulze: The Taxable Future of College Sports

    John T. Holden (Indiana) and Kathryn Kisska-Schulze (Clemson) have published The Taxable Future of College Sports, 77 Ala. L. Rev. 287 (2025). Here is the abstract: 

    College sports are changing. Historically the National Collegiate Athletic Association (NCAA) exercised a strong arm to prohibit college athletes from receiving any form of compensation. Today, a power shift is occurring across the entire college sports arena. Gone are the days of college athlete earnings prohibitions; the NCAA is losing strength and influence, while the athletes themselves are taking to the courtroom to break down century-long restraints on trade. Since 2021, name, image, and likeness (NIL) compensation has become the new norm, revenue-sharing between institutions and their athletes is coming, conferences are expanding to further capitalize on increased broadcast revenue, and the Third Circuit Court of Appeals set the stage for college athletes to one day be deemed employees of their institutions under select labor laws.

    Amidst this rapidly evolving billion-dollar industry, questions have emerged about the potential tax consequences resulting from such changes. Historically, the greater college sports arena largely enjoyed significant shielding from the bounds of taxation. However, as college sports enters a new era that is inherently different and distinct from the NCAA’s archaic ideology of pure amateurism, tax questions relating to the classification of college athletes as employees versus independent contractors, differing earnings models tied to revenue-sharing versus NIL opportunities, and the financial impact of college athletic conference expansion are surfacing. The purpose of this Article is to take a deep dive into the impending tax considerations that could impact the future of college sports.

  • Wallace and Wells: The Past and Future of Taxing “Incomes”

    Clint Wallace (South Carolina) & Bret Wells (Houston) have published The Past and Future of Taxing “Incomes”, 104 N.C. L. Rev. 1 (2025). Here is the abstract:

    For at least half a century, the text of the Sixteenth Amendment—“Congress shall have power to lay and collect taxes on incomes, from whatever source derived”—has been treated by courts, lawmakers, and scholars as giving Congress broad authority to define and tax income, perhaps without any limitation. Recently, however, some members of the Supreme Court started to revive a seedling planted in the 1920s but left for dead: that the “realization rule” should be elevated to the status of a constitutional limit to Congress’s power to determine what is income. With this, we seem to be entering a new era in constitutional tax jurisprudence, focused on the meaning of income and limits to Congress’s power to tax it.

    This Article places realization in broader context, based on a novel investigation of the intellectual and functional roots of U.S. federal income taxation, with a particular focus on the temporality of income. We find commonality between time-conscious income tax theory developed by leading economists in the preratification era (some now largely forgotten), and functional concerns percolating around the same time that we uncover in financial accounting practices and tax administrative guidance. Temporal issues are central: measuring income across time periods is a dynamic and complex undertaking, and theorists and practitioners alike recognized realization as one of many possible, partial resolutions. The history we uncover here dispels the notion, advanced recently by some scholars and Supreme Court Justices, that when the Sixteenth Amendment was ratified there was a common understanding of income that rested solely on realization. It suggests instead that there was not a single meaning of “incomes” as limited to realized gains, but rather that income had different meanings in different contexts.

  • Does the JD Pay Off Financially?

    Following TaxProf Blog posts by Paul Caron and Sloan Speck summarizing new research as to the financial worthiness of the JD degree, summarized in a recent report from the Postsecondary Education & Economics Research [PEER] Center at American University.

    I read TaxProf Blog only intermittently; I learned about the new research via a LinkedIn post from my very own law school, the University of Pittsburgh, touting it this way: “A new study highlighted in The Washington Post reinforces what Pitt Law already knows: a JD remains one of the most valuable graduate degrees, offering strong return on investment and long-term career impact.”

    I read that statement as mostly marketing hype, not to be taken at face value. That is easy for me to say and much less likely to be true, of course, for many recent college graduates who are prospective law students. Pitt, like many law schools, is in the middle of trying to persuade accepted students to put deposits down and commit preliminarily to enroll next Fall. I have nothing to do with those efforts; I read about them in social media just as anyone might.

    My own school’s recruiting tactics to the side, the statement prompts questions that I pose to readers of TaxProf Blog:

  • Christensen & Appleby: Taxing Indigenous Cultural Property

    Grant Christensen (Alabama) and Andrew Appleby (Tennessee) have posted Taxing Indigenous Cultural Property, 52 BYU L. Rev. (forthcoming 2026). Here is the abstract:

    What is the value of something that cannot legally be sold?  This question lies at the heart of a growing tension between federal tax policy and Indigenous rights.  Although federal law prohibits the sale of eagle feathers, the IRS recently sought to collect a $29.2 million estate tax assessment on artwork incorporating a bald eagle—even while acknowledging the beneficiary could not legally sell the artwork to satisfy the tax liability.  Though the parties ultimately settled, this case exposes a dangerous precedent demanding a comprehensive response.

    This Article argues that Indigenous cultural property should be exempt from federal and state taxation and subject only to regulation imposed by Native communities themselves.  Imposing a “tribal only” regulatory scheme for cultural property is both consistent with the underlying purposes of tax law and the federal government’s broad commitment to support tribal self-government and protect tribal sovereignty.

    We build our normative claim upon two centuries of precedent and practice.  Drawing upon the underlying purposes of tax law, tribal law, and federal Indian law, this Article constructs a robust defense for Indigenous cultural property’s exclusion from federal regulation.  Our argument rests on two foundational premises.  First, inherent tribal sovereignty reserves to tribal governments the authority to govern the cultural and internal values of their communities.  Second, federal tax law has no overriding interest in interfering with the inheritance of cultural property between tribal members or in collecting revenue on property that cannot legally be sold.  From these premises, a natural consequence emerges: non-tribal regulation of this patrimony should be broadly prohibited.

    The implications are profound.  If adopted, our proposal would free tribal members from the burdens associated with transferring cultural property under non-tribal law and would ensure Native Nations that the property forming the basis of their identity is free from federal and state encumbrance.

  • Ups and Downs of Law School Applications

    Over on LinkedIn, Mike Spivey, CEO of Spivey Consulting and a familiar name in the world of law school admissions consulting, wrote last Friday that overall applicants in this cycle are up +10.6% at this point, roughly (as he writes) 90% done with the cycle, compared to being up +33% early in the cycle. He characterizes the “steep glide-path” down from the early applicant numbers as being even sharper than his firm’s “most sophisticated data modeling using time smoothing.”

    He also has some choice words for LSAT score inflation at the high score bands.

    For those with LinkedIn accounts, the full post is here.

  • Big Tech Legal Fight Looming After Utah Enacts Targeted Ad Tax

    Utah has officially joined the digital advertising tax movement, following Maryland and (most recently) Washington State. As Bloomberg Law notes, “Big Tech” is sure to challenge the Utah tax. Although all three states are targeting the same general activity and the same general class of taxpayers, and use a gross receipts approach, each state’s statutes differ in meaningful ways, as discussed below.
