Supreme Court Decides Our Tariff Case - and We Won!
In a 6-3 decision, the Court ruled that the International Emergency Economic Powers Act does not authorize tariffs.

Today, the Supreme Court decided our case challenging Donald Trump's massive IEEPA tariffs. In a 6-3 decision, Court rightly ruled that the International Emergency Economic Powers Act does not give the President the power to "impose tariffs on imports from any country, of any product, at any rate, for any amount of time." It's a major victory for the constitutional separation of powers, for the rule of law, for free trade, and for the millions of American consumers and businesses enduring higher taxes and higher prices as a result of these tariffs.
Our case was filed by Liberty Justice Center and myself on behalf of five small US businesses. We were later joined by prominent Supreme Court litigators Michael McConnell and Neal Katyal. Michael became our chief counsel for the Supreme Court phase of the litigation, and Neal skillfully conducted the oral argument before both the Federal Circuit and the Supreme Court. A case that had its origins in a blog post laying out some legal theories and another one recruiting potential clients went all the way to the Supreme Court and culminated in an important victory. Earlier, we prevailed in the US Court of International Trade (the trial court with jurisdiction over cases involving trade policy) and again in the US Court of Appeals for the Federal Circuit.
Chief Justice John Roberts wrote the opinion for the Court, which concludes that IEEPA's grant of authority to "regulate" importation in response to an emergency that qualifies as an "unusual and extraordinary threat" to the US economy, national security, or foreign policy, does not include the power to impose tariffs. He, Justice Neil Gorsuch, and Justice Amy Coney Barrett also based their conclusion in part on the major questions doctrine, which requires Congress to "speak clearly" when authorizing the executive to make "decisions of vast economic and political significance." The three liberal justices - (Kagan, Sotomayor, and Jackson) did not join this part the opinion, because they argued that ordinary principles of statutory interpretation were enough to resolve the case.
The Supreme Court today also decided a case against the tariffs brought by 12 states led by the state of Oregon (they prevailed, too). The court dismissed for lack of jurisdiction the Learning Resources cases, because they held it should have been filed in the US Court of International Trade (where we filed ours).
The implications of the ruling for future administration efforts to impose tariffs are not completely clear. But I believe it will not be possible for the president to replicate the massive, sweeping worldwide tariffs he tried to do under IEEPA. Today's ruling also signals that a majority of the Supreme Court is skeptical of claims of virtually unlimited delegation of tariff power to the president.
I want to commend the Liberty Justice Center and their litigation team led by Jeffrey Schwab for bringing this case at a time few other groups were willing to do so, and Michael and Neal and their respective firms for their extraordinary work in conducting the appellate phase of the litigation. I also want to recognize our clients for their courage in joining this cause, and enduring the resulting public and media scrutiny, and the potential risk of retaliation by the administration. Many others - too many to list here - also deserve credit and thanks. It was an honor to have played a modest role in this case, myself.
I will likely have more to say later. In the meantime, for a compendium of my previous writings related to the tariff litigation, see here.

Wow! Congrats!
I think this might have been the most consequential SCOTUS case of my lifetime.
From a policy perspective, there might be some that have a bigger impact. But this case was the clearest example I've seen of the law being pitted against politics.
The case against tariffs was as clear a case as you'll see at that level. But it involved a signature policy of a President who has been openly defiant of courts, and who is ideologically aligned to 6 of the justices.
There was a real worry that 5 of those 6 justices might choose to ignore the law and rule with the President, which would be a terrifying precedent.
Anderson v Trump and Trump v. United States are far more consequential. The first eliminated the requirement that the President be loyal to the US and the second green lighted presidential criminal acts. Both of which Trump has run with to the extreme.
The US was never going to disqualify a strong political candidate unless it was absolutely black and white (ie, not a natural born citizen), and Gerald Ford established the norm against prosecuting former Presidents.
But there was a real risk they'd let Trump keep the tariffs, which would basically mean an ideologically aligned President could do anything they wanted without the approval of the legislative branch.
The Constitution required Trump to be disqualified from office. It was quite black and white. This is an example of the Republicans just ignoring parts of the Constitution they don't like.
It's one thing for Ford, on a case by case basis, to decide to preemptively pardon Nixon. It's thing to have a bright line rule that says presidents cannot be held accountable. At least before they had to look over their shoulder.
But as it stands now, Trump could order the Army to arrest and execute the six Supreme Court justices who just ruled against him, and not have to worry about any future consequences. Maybe that would be too much for even this Congress and they might remove him from office (at which point he sends the Army to arrest them too), but so long as its arguably within the scope of his duties he's home free.
I thought it more likely to be 7-2. I wasn't expecting Kavanaugh to dissent.
This is the most haphazard SCOTUS ruling I have seen in a while. The dissent is grasping at straws.
Two words: Phyrric Victory.
Trump now has an excuse for an economy that isn’t very good, any he can bash foreigners and rail up resentment against illegal aliens in the process. Do you want to see true, white supremacy, just wait..
This is one more reason to dump the filibuster now and pass the safe act and then pass another bill that puts a 130% tax on any refunded tariff, Congress can do that (remember the Obamacare tax?).
And then he came out and say something he hasn’t said recently tell the working class which includes the blacks that they be making 34 dollars an hour or more if we only threw the damn leagues out of the country. And that’s somewhat true, but that doesn’t matter.
Ilya, I know you’re not an American, but that’s not an excuse not to know American history. Look up the know nothing movement and how nasty that got.
Like I said Phyrric Victory…
The economy wasn't good last year with Trump's tariffs: GDP growth and job growth were both the lowest since COVID, manufacturing jobs fell, the US trade deficit in goods rose to its highest level on record. Is he going to blame all of that on a SCOTUS decision striking down those tariffs the following year?
BTW, Congress doesn't want tariffs already, what makes you think they'd bail Trump out for this loss now that they've been declared illegal?
Plus the whole idea that it can be a winning political message for a President to say, "hey, the economy sucks, but that's the fault of the SUPREME COURT, so um, vote for me/my party!" lacks, let's say, much historical precedent.
Also, Congress isn't going to abolish the filibuster over this.
Also, Ed, you keep wanting to make Know Nothings happen, and you're doing a good example of literally being one, but, like "fetch," it ain't happening.
I think running on anger against the Supreme Court could be a viable strategy, but it's made more difficult when your own Supreme Court nominees are ruling against you.
Tarrifs were never going to save the US from Trump's lies and fascism.
Trump can say all that but nobody except his nutty base will believe it.
"The economy would be better if I could do (more) illegal things," yeah that's a winning argument.
I doubt this will be the Pyrrhic victory you claim - I think for the majority of Americans, they will see this as another example of Trump behaving without authority.
Props to you for conceding that the Trump economy isn't good, though.
The conflict has begun on February 20. The enemy wears robes and claims ancient feudal rights to deny the will of the people. No quarter must be given and no remedy refused.
^furiously typed between large handfuls of Cheetos.
Denying the will of the people by stopping the executive from doing something the Constitution and laws do not allow? That's the will of people? Really?
I opposed such thinking when Obama was president. I equally oppose it now.
Well done, Ilya.
Congratulations!
Digging through the opinions at the trial court and appeals court, all I'm seeing is that the tariffs are enjoined. But no mention of orders on refunds. How does that work? Is there separate law that already covers this? Does the court need to order refunds?
It will all be converted to Kohls Cash, like the class action settlements paying via coupons.
You can either have an opinion finished quickly, or you can have a decision which answers more questions but takes longer.
Since the Court also ruled that the only court with jurisdiction is the Court of International Trade, it seems obvious that court, having both expertise and authority, will be the venue to sort that out.
How is my life better as a consequence of this decision?
While I don't think "how would this benefit Kleppe" is necessarily a question the Supreme Court was trying to answer, affirming the separation of powers is generally a good thing. At least among those who care about those sorts of things.
Price stability and free trade are good for your material interests.
Tariffs are taxes imposed on imported goods, which causes costs to increase for importers. Businesses importing goods typically pass some or all of that added cost on to consumers in the form of higher retail prices, and domestic producers may also raise their prices because the tariff reduces foreign competition. So if there are no more tariffs, you will pay lower prices. Most consider that a good thing.
I'm old enough to remember when conservatives believed a lot of things they apparently no longer do, such as laws being made by Congress rather than the executive. Maybe this decision will be a step in the direction of restoring that.
Not this conservative. Also, Trump is not a conservative, despite occasionally doing conservative things. That's why I don't think he should be president. Much of MAGA is not conservative; they just want a basket of things they want.
Point taken, and I'm sure there are principled conservatives who held their nose and pulled the lever for Trump because they thought the alternative was worse. However, the reality is that that was a Faustian bargain, and eventually the devil is going to show up and expect payment.
I've tried to see this from the other side. I'm a Democrat. If there were a Democrat who were the mirror image of Trump but who was giving me policies I like, would I vote for him? I'd like to think no, but who knows. Maybe human nature really is that keeping the other guy from winning is all that matters.
As it stands, though, for all the Democrats' faults, flirting with open fascism is not one of them.
Here's a very good real-world example based on real life, from the Biden administration:
If I had tens of thousands of dollars in student loan debt would I favor the ability of the president to cancel that debt?
That's a tough one for the individual making the choice. Perhaps the honest answer is, "no, I wouldn't favor the ability; but I'd vote for the guy."
I am always happy to be on the same side when a correct decision is rendered.
A couple of questions:
Does the opinion(s) give any sense of why the SC took as long as it did to announce the decision?
And can someone reconcile today’s opinions with past decisions? In particular, Alito and Thomas, who I (foolishly?) believed were adherents to the major questions doctrine? As well as the three liberals, who previously hadn’t disliked many assertions of presidential power?
Are you incapable of reading the actual text of the released decision? That should tell you why.
No, you didn't really "win". Because you don't believe the federal government has any legitimate authority to implement any national border restrictions, including tariffs.
Personally I'm happy with the result, but I'm looking forward to those who condemn an arch conservative court overturning sacred precedent--because that's what Roberts did here, dismissing the prior (thin reed) intermediate court decision about the IEEPA's predecessor language, saying that alternative would have been unconstitutional. Because of MQD/non-delegation principles (must be explicit and constitutional), even if the lib justices pretend otherwise. I look forward to such reasoning being applied faithfully in the future. Even if it means overturning other precedents.
Sorry, what was the "sacred precedent" the Court overturned here exactly?
It's right there in my previous, the IEEPA's predecessor language and the Nixon precedent (addressesd by the chief I believe).
I want similar reasoning applied to the environmentalist's tortured view of environmental law and regulation.
People outraged that the Court struck down Biden's attempt at student loan forgiveness applauding now. And fairly, those outraged now but who applauded striking down loan forgiveness.
Seems a reasonable decision. Regardless of what you might think of tariffs as a policy matter, it was a stretch for Trump to claim the power to impose them without a clear statutory basis. And I don't think the basis here was clear.
