Happy to announce that @anthonytaboni.bsky.social and I have created a new dataset of the Supreme Court's Shadow Docket actions from 1993-2025. A paper describing the data and a website with the data and documentation are here:

Repubs may eventually nuke supermajority cloture on CRs or even on all appropriations bills. For now, they seem to like shutdown politics. That may not be true in 45 days.

I see many of you saying that it's obvious Republicans are responsible for the upcoming shutdown and Dems just have to say so but I would ask you to step back and ask yourselves what you would be saying if Dems had unified government and a clean CR was being blocked by a GOP filibuster.

The Supreme Court’s history is full of justices making up facts and history and then establishing rules based on those facts. What distinguishes this Court, I think, is that it is doing so in an environment where they have so much access to so much information.

These Kavanaugh Stops keep seeming to be a lot more invasive than Kavanaugh tried to pretend they would be.

The extent to which Justices just make up facts, history, psychology, etc etc etc to get the outcomes they want, and the legal community as a whole just shrugs is … legit appalling.

As immigration agents have escalated their tactics, US citizens, many of them Latino men, have been stopped and in some cases taken into custody by law enforcement officers. Allison, Jenny and I took a closer look at the encounters. www.nytimes.com/2025/09/29/u...

Six Justices conclude it's likely the Impoundment Control precludes an otherwise valid APA claim to require expenditure of obligated funds. This argument, which turns the ICA on its head, is so absurd that the Trump DOJ itself wisely disclaimed it a month ago.

The supreme Court is allowing Trump to *temporarily* do something that its own precedents and congressional statute say he cannot. As with so many of its recent decisions, there is no way for them to undo the damage their decision does. They do not preserve the status quo - they stack the deck.

#BREAKING: Over dissents from Justices Sotomayor, Kagan & Jackson, #SCOTUS grants a stay in the Slaughter case (allowing President Trump to remove the last Dem member of the FTC), *and* grants certiorari "before judgment" to decide whether to formally overrule its 1935 ruling in Humphrey's Executor.

Dahyun Choi @dahyunchoi.bsky.social studies how private and public organizations strategically use expertise in the U.S. administrative state. Her job market paper shows that while high-quality studies remain resilient to political turnover, partisan bias still shapes which evidence agencies use.

I'm a little older than Osita and remember the pre-election consensus that there was very little difference between Bush and Gore. Peak Media (when it was making a ton of money and the internet hadn't blown it up) kinda stunk

Not really an overstatement to say that the test of a free society is whether or not comedians can make fun of the country's leader on TV without repurcussions.

If I were one of 9 members of an institution as responsible as any for all this, I think I’d refrain from throwing stones at other institutions, but that’s just me.

Sotomayor also took aim at lawyer-lawmakers, who really should know better:

"Every time I listen to a lawyer-trained representative saying we should criminalize free speech in some way, I think to myself that law school failed."

Those are some wild quotes for sitting COA judges from the bench.
"They cannot get amnesia in the future because they didn't write an opinion on it. Write an opinion," Wynn said. "We need to understand why you did it. We judges would just love to hear your reasoning as to why you rule that way. It makes our job easier. We will follow the law. We will follow the Supreme Court, but we'd like to know what it is we are following." "The Supreme Court's action must mean something," said Judge J. Harvie Wilkinson III, a Reagan appointee. "It doesn't do these things just for the kicks of it."

But, let’s be clear what John Roberts did this morning:

Roberts effectively overturned the Humphrey’s Executor precedent and both lower courts’ rulings in this case in order to allow Trump to fire Slaughter for now — on the shadow docket and through an “administrative” stay issued by him alone.
