I'm late to the news that a cert petition has been filed in the US v. Chatrie geofence case. Thanks to Adam Unikowsky and the EDVA public defenders' office for the shout-outs. Fingers crossed for a grant.

I recently came across this Ohio Court of Appeals case that adopts the Carpenter Test overtly - the first court to do so! (Hundreds of courts have used these factors informally.) Thank you to Judges Mental, Boggs, and Edelstein for their kind references to my work.

In dramatic reversal, Senate votes to kill AI-law moratorium A GOP-led bid to stop states from regulating AI collapsed after a deal to save it fell through.

In a stunning reversal, the Senate voted 99-1 this morning to strip from Trump's big bill a 10-year moratorium on state-level AI regulations.

That's correct

The Senate Parliamentarian asks Senators to rewrite the proposed 10-year moratorium on state AI regulation. An important development that might limit the scope of this extremely wrongheaded provision.

(It might also be removed by amendment because many Senators of both parties oppose it outright).

If you could get a review copy of this to me (and even if you can't) I might write a review of this when it comes out. The Church Report is pretty foundational to Fourth Amendment and surveillance studies.

The Supreme Court unanimously holds that a lawsuit can proceed against an FBI SWAT team for raiding the wrong house.

Our new paper, Decentering Property in Fourth Amendment Law is now out in the U. Chicago Law Review! It argues that property concepts should be used very carefully, and very little, in modern Fourth Amendment law.

Are many law professors on Linkedin? I've never tried it.

I largely side with the Princeton School folks on AI timelines. I don't think supercapable AI is just around the corner. But I side with the AI 2027 folks on the need for robust regulation of this dangerous technology. We need more than these two viewpoints.

It's also kind of funny to have a major case named Case.

The Supreme Court grants Case v. Montana, on whether police need Probable Cause to enter a home for community caretaking purposes (i.e. to break up a fight or save a heart attack victim). Interesting case! It'll be nice to have clarity on the issue, whatever happens.

Not directly, but DOGE might grab this data after the intelligence agencies buy it, and combine it with other government data.

Timely book 👇

It's unclear just how many and how often police departments purchase sensitive private data. But intelligence agencies appear to be buying it regularly and on a massive scale.

@sjquinney.bsky.social law professor @mtokson.bsky.social talked to Sidebar co-host Amanda Pampuro about the challenges associated with regulating AI during its infancy.

Michael C. Pollack (@michaelcpollack.bsky.social) & Matthew Tokson (@mtokson.bsky.social) expose the flaws of property-centered Fourth Amendment law, showing how it can be manipulated, exclude digital privacy, and leave society’s most disadvantaged with the least protection.

Volume 92.3 is now live, featuring pieces by Conor Clarke & Henry Hansmann; @michaelcpollack.bsky.social & @mtokson.bsky.social; Adriana Z. Robertson, Pat Akey & Mikhail Simutin; and Aziz Huq. You can find them all here: lawreview.uchicago.edu.

As a Celtics fan, I'd rather see them than OKC. The Thunder are terrifying.

I have a new piece in Lawfare on AI policing and how it facilitates authoritarianism.
