There's nothing better than watching your kids fall in love with nature. Our national parks are worth fighting for, and need our support (now more than ever)!

Coding’s always been a hobby, and I first made nunn.ai back in 2024 as a fun side project to help others learn evidence law. Since then, it’s grown way more popular than I ever expected. But I’m taking it offline today, at least until I can make sure it’s a net positive for legal research.

Had a great time at the biggest Evidence Summer Workshop yet! What an awesome scholarly community. Thanks my co-organizers Ed Cheng, @alexnunn.bsky.social, and Julia Simon-Kerr. #ESW

My genuine reaction when a student just told me he's been "lawmaxxing for finals"

It's pencils down at the hackathon. I put 236 years of US copyright law into a git repository. Every Act of Congress from 1790 to today is a commit. Still some work to be done, and things got frantic at the end, but I'm proud of this! github.com/katelynsills...

Incredibly indebted to Yoto Yokoyama (Tohoku Gakuin University) for his translation of Ed Cheng's and my Texas Law Review article, "Beyond the Witness: Bringing a Process Perspective to Modern Evidence Law." Yuto's translation was just published in the Hiroshima Law Journal. Many thanks!

Very excited to see the sixth edition of the “Exculpatory Evidence” treatise now in print! Getting to work with Ed Imwinkelried on the project has been such a joy.

Delighted that my paper with Myriam Gilles, Procedure’s Unmooring: How the Federal Rules Lost Their Way, will be coming out in the Penn Law Review. More soon!

I’m excited to share that my latest article, “The Multidimensions of AI Chatbots as Evidence,” is now forthcoming in the U.C. Davis Law Review. The abstract is below, and I plan to have it up on SSRN soon.

Some profs are using AI to write articles. @mbkplus.bsky.social and I size up this worrisome trend and its impact on the academic enterprise. @mbkplus.bsky.social proposes granular disclosure rules whereas I foresee a world where AI will soon write articles and make the publishing decisions. Gulp.

One fascinating trend in this data. In 1971 alone, the Supreme Court cited 138 student notes and comments in its opinions. But that number has dropped off dramatically, as the Court hasn't cited more than 10 in a single term since 1997.

A historical look at the Supreme Court's citations to scholarship. A marked increase in the 1960s that's endured at a steadily growing rate.

At its zenith, Evidence was one of law’s most celebrated fields. Since the FRE’s codification, however, the field has fallen to dead last in citation rankings. But a remnant of its former glory remains, as Wigmore (#2) and Greenleaf (#7) *still* appear on a list of SCOTUS’s most cited scholarship.

My new paper, The Article III Factfinding Power (forthcoming in the Minnesota Law Review), is now up on SSRN. I'd welcome your thoughts and comments as I continue to improve the piece! papers.ssrn.com/sol3/papers....

I'm honored to be publishing this piece with Vanderbilt Psych Prof Sarah Brown-Schmidt in volume 112 of the Virginia Law Review. In this empirical evidence law and cognitive science article, we identify the risks posed by "hear-witnesses" who inaccurately recall and recount statements at trial.

There's been so much fantastic Evidence scholarship lately. Add this to the list!

Happy to share that Developmental Evidence Rules is forthcoming in the California Law Review! What would it mean to take childhood seriously in evidence law? This article takes up that question.

What an incredible gift from a student! 😃

Excited to share two projects, forthcoming in the Minnesota Law Review and the Notre Dame Law Review, about federal courts’ increasing reliance on “external” factfinding of epistemically dubious provenance. (1/4)

I had an amazing time chatting with @aseesbhasin.bsky.social and Jasmine Gonzales Rose about their fantastic new article, "Antiracist Expert Evidence," which was recently published in the @yalelawjournal.bsky.social. Listen below! excitedutterance.com/listen/2026/...

Thrilled to share that 𝐺𝑢𝑖𝑙𝑡 𝑏𝑦 𝑃𝑎𝑟𝑒𝑛𝑡ℎ𝑜𝑜𝑑 has found a home with the Yale Law Journal. This piece examines parental liability regimes and parental rights, and how they are connected by a shared logic that harms children and families. Thank you to all those who read drafts and offered feedback!

It’s day 5 of being snowed in, and I’ve officially hit the “explain the character evidence prohibition” phase of trying anything and everything to keep my kids entertained. (And, in case you’re wondering, they think law students *always* have to keep their hands raised.)

Texas’s highest court holds that the Confrontation Clause required witnesses to testify unmasked during the Covid pandemic so the jury could evaluate their demeanor and credibility. And so regrettably, evidence law’s predilection for “folk psychology” marches on. www.nunn.law/blog/covid-c...

After surveying the divergent perspectives of all nine justices, I came to two conclusions. First, the era of reliability principles in Confrontation Clause jurisprudence is well and trial over. Second, the post-Crawford primary purpose test is safe, but for differing reasons.

Justices Alito and Gorsuch recently called for “reconsideration” of Crawford v. Washington, signaling potential upheaval for Confrontation Clause jurisprudence. Will the Court jettison more settled doctrine? In my new blog post, I offer a prediction. nunn.law/blog/revisit...

Today's blog post: "Supreme Court of Kentucky Finds Raw, Machine-Extracted Data Does Not Implicate the Confrontation Clause": www.evidenceprofblog.com

It’s easy to overlook Rule 401, but its low bar for relevance reflects a hugely consequential policy choice regarding how to best allocate decisionmaking power between judge, jury, and rulemakers. My thoughts on @aseesbhasin.bsky.social’s engaging new article: nunn.law/blog/asees-b...

Proposed Federal Rule of Evidence 707 is the FRE's first response to the "AI Era." It would be a good first step, but there's much more to work yet to be done. nunn.law/blog/propose...

I just bought this photo, simply labeled "Old Judges," at an estate sale for $3. Little did the seller know that it's actually an original, official portrait of the Fuller Court from its Lochner term. That means, if my calculations are correct, I'm looking at an appraisal value of *at least* $7.

I've posted a draft of my next article, "The Administrative Law of McCarthyism," forthcoming in the Stanford Law Review, on SSRN. Comments and feedback are very welcome! papers.ssrn.com/sol3/papers....

A boycott might have been a tad extreme, but how did we get to the point where con law largely dominates the academy?

Oh dear. RIP to one of the great ones, as a scholar and as a person.

One of the more trivial annoyances I have with AI is the widespread skepticism it’s brought to em-dashes. I love em-dashes! I’ve used them liberally in my articles for a decade. But now, I avoid them when writing, given their association. Not the worst consequence of AI, of course, but a bummer.

Very excited to hear about this symposium, featuring three fantastic colleagues!

📢 Harvard Law Review Symposium Announcement: "Judicial Review in Jeopardy?" Panel discussions on October 10; print publication in June. Honored to work with co-organizer Neil Siegel and these other excellent scholars on such an important (and timely) topic ⬇️

Huge thanks to everyone who has offered incredible feedback on nunn.ai over these past few months! It's still very much a work in progress, but it's been exciting to watch nunn.ai grow as a free platform for democratizing access to evidence law. Try it out, and let me know what I can improve!

The best day-and-a-half of the year is always the Evidence Summer Workshop! We had everything from formal modeling to queer theory to analytic philosophy to doctrinal analysis. Thanks to my co-organizers Ed Cheng, Julia Simon-Kerr, and @alexnunn.bsky.social.

Arrived to @vanderbilt.edu for tomorrow’s Evidence Summer Workshop. Excited to spend two days with this evidence community. Thanks to the program committee of Ed Cheng, @alexnunn.bsky.social, @maggiewittlin.bsky.social, and Julia Simon-Kerr for organizing, and to all others helping out! #ESW

I often return to this amusing anecdote from Thomas Grey. Amid the heyday of formalism, the Harvard faculty threatened to withhold support for the University of Chicago's fledgling law school because Chicago planned to offer courses on "unscientific" public law topics like . . . Constitutional Law.

Thanks so much to my amazing students at Texas A&M!

My Public Comment in Strong Opposition to the Proposed Amendment to the Prior Inconsistent Statement Hearsay Exclusion: tinyurl.com/5cvp3kj3

The internal deliberations of the law journal that rejected me seven minutes after submission:

We had a great DC launch reception for the Texas A&M Center on the Structural Constitution last night! It was an honor to speak w/Chief Judge Sri Srinivasan & Judge Neomi Rao of the D.C. Circuit on the importance of studying structural constitutional law.

Look what my friend @alexnunn.bsky.social made! 💅

This is crazy impressive!

I’m very excited to introduce wigmore.ai, an AI platform for learning and understanding evidence law. Named after the legendary scholar, it's designed to provide clear, professor-style explanations for all your evidence law questions.

Tried to save some time editing by using Find & Replace. But now, after encountering the curious typo "Federal Rulesquently" for the third time in as many pages, I think I might have made a mistake...

Furthest I ever got: Atty: What is your occupation? Me: Teacher. Atty: What do you teach? Me: Law. Atty: Which courses? Me: Civ Pro. And Evidence. Judge: Really? Which book do you use for Evidence? I teach it too as an adjunct! Was dismissed soon after….

Another extraordinary Evidence Summer Workshop in the books! Great ideas, great conversation, great people. Thanks to Ed Cheng for lead organizing and @alexnunn.bsky.social and Julia Simon-Kerr for co-organizing. #ESW
