Forgot to post: Our article on Decentering Property in Fourth Amendment Law is out in final form in the UChicago Law Review! lawreview.uchicago.edu/print-archiv...

What do you say to newly graduated lawyers in the US at a time like this? Here were my Commencement remarks at the University of Chicago Law School graduation Saturday. I told four inspiring students’ stories. www.law.uchicago.edu/news/learnin...

I’m honored to be the faculty speaker at the University of Chicago Law School Commencement today. The livestream starts at 11:30 am Central, and I’ll be joined by our distinguished alumnus speaker, Judge David Tatel. www.law.uchicago.edu/graduation

Cool and important paper alert! 🚨

🚨Publication Day for Sidewalk Nation!🚨 Sidewalks connect us all, and they connect commerce, tech, tax, property, policing, homelessness, surveillance, free speech, socioeconomic equity, public health, climate resilience, and more. www.hup.harvard.edu/books/978067...

The Markup recently published a terrific piece about the ludicrous processes for protecting the privacy of electronic health information amidst dark patterns. It reflects a bunch of good research by Alex Rosenblat. Read it here: themarkup.org/privacy/2026...

I'm excited to share two new opportunities today to hear and read more about Sidewalk Nation (which you can order via @harvardpress.bsky.social and other sellers here: www.hup.harvard.edu/books/978067...): First, I have this op-ed today in Governing Magazine! www.governing.com/infrastructu...

A fun bit of @uchicagolaw.bsky.social history today during reunion weekend: the unveiling of Geof Stone’s portrait.

Sounds like a 7-2 loss for the government on birthright citizenship, with Court perhaps deciding it on statutory grounds, as suggested by Kavanaugh’s questions to Wang. But does the canon of constitutional avoidance apply when the Court has a 100+ year old precedent resolving the same Con Law issue?

A disturbing new piece on how dark patterns have become pervasive on the US Postal Service partner website for processing change of addresses / new voter registration. You want to register to vote? Sure thing, but first buy this Internet access / pizza / furniture, etc. www.wired.com/story/the-go...

Theo will be a phenomenal Justice. I am so happy for him, his family, and the Evergreen State!

2025 annual report of the California Privacy Protection Agency has dropped. Lots going on in the Golden State regarding privacy. privacy.ca.gov/wp-content/u...

I love this article, because it's such a clear illustrations of an important point. The West Village is becoming a victim of its own strict zoning. The little details about the inhabitants show us how (thread).

These housing reforms would be spectacular.

This would actually be perfect. At last night’s (excellent) one-man on a piano show in Chicago he did a riff about being a teenager uninterested in football who was seated next to Ron Jaworski at an Eagles game. (Also, Hysterical is a good album.)

It still amazes me that only 3 US states (IL, TX, and WA) provide meaningful protection against this kind of use of biometrics. In those states it’s impractical to get consent to use the feature from people without Facebook/Instagram accounts. What are the other state legislatures waiting for?

Plenty of empty seats formerly occupied by New England fans.

Touchdown Seahawks!

These ICE OUT towels were being confiscated by security on the way into Levi stadium. No other towels were prohibited.

Excited that our paper with @thelior.bsky.social @mbkugler.bsky.social , “Can Consumers Protect Themselves Against Privacy Dark Patterns?” is a winner of the (@futureofprivacy’s or @futureofprivacy.bsky.social’s) 16th Annual Privacy Papers for Policymakers Award! Read more: fpf.org/press-releas...

And to have the chance to exorcise the ghosts of the Pats loss? Unreal stuff.

Bobo has always been the Seahawks’ secret weapon. Saved him for the right time.

We are calling this the Cale Mary right?

I got to the part in this story where someone SYNTHESIZED A DRUG THAT GIVES SOMEONE PARKINSON’S OVERNIGHT and went 😮 😧 😮 😧 😮 😧 😩

Dark patterns are in the news again, this time with antitrust implications, as well as privacy.

Downzoning was used by cities around the world to preserve neighborhood aesthetics & protect property values. New evidence from Chicago in @findingspress.org ⏬ shows downzoning's effects over several decades: —Massive drop in housing construction —Higher home prices —Increased racial segregation

Former UVA president Jim Ryan, who resigned over the summer due to pressure from the Trump Administration, just shared this 12-page letter with the Faculty Senate, detailing his experience with the Board of Visitors and DOJ. It's a surreal--and troubling--read. drive.google.com/file/d/1Is6x...

Can confirm that travel out of LGA is brutal this evening. Numerous planes stuck on the tarmac despite many cancellations and delayed departures. Now 3 hours late and counting with no end in sight. Pilot is getting virtually no guidance from air traffic control. I guess this I the new normal.

wheeeeeeeeee!

Thanks to @jtlg.bsky.social for inviting me to discuss my 2007 book review, Wealth Without Markets? in his Cornell Tech seminar later today. It was super-fun to revisit my debate with Yochai Benkler after so many years, with the benefit of hindsight. www.yalelawjournal.org/pdf/556_p1zn...

On the 575th pitch! What. A. Game.

My newest published paper is out! It's about TikTok. It's also about the constitutionality of U.S. data privacy regulation. I don't know which topic is more popular - could someone with a teen ask? If you're interested in either, download it below. papers.ssrn.com/sol3/papers....

I’m honored to be giving this upcoming lecture at my alma mater. Go Bears!

New book out now from ‪@universitypress.cambridge.org‬! Law and the 100-Year Life, co-edited by Solomon Center scholars, reimagines how laws and the institutions they shape—from labor to healthcare—must evolve in a world where more of us than ever will live to 100. law.yale.edu/solomon-cent...

We just posted a major new study of AI models and books, showing that some (but not all) models memorize large portions of some (but not all) books after training on the books3 database With A. Feder Cooper and Amy Cyphert, among others arxiv.org/pdf/2505.12546

Aziz Huq and @thelior.bsky.social shared legal insights alongside Chicago Quantum Exchange director David Awschalom at a panel moderated by Robert W. Karr Jr., a partner at Barnes & Thornburg LLP. The discussion kicked off an interdisciplinary CQE–led effort aimed at strengthening the growing field.

Big news on the constitutionality of tower dumps / geofence warrants…

You never know who you are going to run into on the UChicago campus. Thanks to Transportation Secretary @petebuttigieg.bsky.social for spending time teaching our students at the Institute of Politics and cheerfully indulging our faculty paparazzi.
