As SCOTUSblog readers are likely aware, tariffs are taxes charged on goods bought from other countries. In February, President Donald Trump imposed dozens of new tariffs. Now the Supreme Court will decide whether he had the legal authority to do so.
The stakes in the litigation are enormous. Tariffs are a crucial part of Trump’s agenda, with huge consequences in the United States and throughout the world. Indeed, after the U.S. Court of Appeals for the Federal Circuit struck down most of the tariffs, Trump said that their invalidation “would be a total disaster for the Country” and “would literally destroy the United States of America.” In the Trump administration’s petition to the Supreme Court, the solicitor general said “the tariffs are promoting peace and unprecedented economic prosperity” and “pulling America back from the precipice of disaster” and “restoring its respect and standing in the world.”
But the issue that the Supreme Court will decide is not whether the tariffs are desirable. Rather, the legal question is whether the International Emergency Economic Powers Act authorizes the president to impose tariffs via executive order.
The issue is thus one of statutory interpretation. Conservative justices long have embraced textualism and stressed that laws should be interpreted based on their plain meaning. As the Supreme Court declared in the 2004 case of Lamie v. United States Trustee, “It is well established that ‘when the statute’s language is plain, the sole function of the court—at least where the disposition required by the text is not absurd—it is to enforce it according to its terms.’” And just last term, in Stanley v. City of Sanford, Florida, Justice Neil Gorsuch wrote an opinion for the majority stressing textualism in interpreting statutes, sharply disagreeing with Justice Ketanji Brown Jackson’s approach of focusing on a law’s purpose to determine its meaning.
This is directly relevant to the tariffs case. Trump relies on the IEEPA, a statute adopted in 1977, to provide the legal authority for the tariffs he imposed. The IEEPA, though, does not mention tariffs. It authorizes the president to “regulate . . . importation” to “deal with any unusual and extraordinary threat.” As the Federal Circuit noted, other statutes that grant the president tariff authority expressly refer to “tariffs” or use synonymous terms. The court of appeals explained that “when drafting IEEPA, Congress did not use the term ‘tariff’ or any of its synonyms.” The court concluded that “[t]he absence of any such tariff language in IEEPA contrasts with statutes where Congress has affirmatively granted such power,” and where “Congress intends to delegate to the President the authority to impose tariffs, it does so explicitly, either by using unequivocal terms like tariff and duty, or via an overall structure which makes clear that Congress is referring to tariffs.”
Even beyond textualism, another doctrine created by the conservative justices, the “major questions” doctrine, undermines any claim of presidential power to impose tariffs under the IEEPA. In recent years, the six conservative justices repeatedly used the major questions doctrine – which requires clear guidance from Congress before a federal agency can act on a major question of economic or political significance – to strike down actions by the Biden administration.
In the 2022 case of National Federation of Independent Business v. Department of Labor, Occupational Safety and Health Administration, the Supreme Court, by a vote of 6-3, invalidated the Biden administration’s mandate that employers require vaccination or COVID-19 testing in workplaces of more than 100 employees. Although the court did not explicitly mention the major questions doctrine, that was the rationale: Congress had not given sufficiently specific authority for imposing the vaccine mandate.
In the 2022 case of West Virginia v. Environmental Protection Agency, the court held, again by a vote of 6-3, that the EPA lacked the authority to regulate certain greenhouse gas emissions from coal-fired power plants. Chief Justice John Roberts, writing for the majority, said that this was a major question of economic and political significance and Congress had not provided sufficiently specific authority for such regulation.
In the 2023 case of Biden v. Nebraska, the court, in another 6-3 decision, struck down the Biden administration’s student loan relief program. Even though a federal statute allowed the Secretary of Education to “waive or modify” student loan debt, the court, once more in an opinion by Roberts, said that this was a major question and there was not sufficient congressional authorization.
The Federal Circuit applied these precedents to hold that Trump lacked authority to impose the tariffs. It stated that imposing “tariffs of unlimited duration on imports of nearly all goods from nearly every country with which the United States conducts trade” is “both ‘unheralded’ and ‘transformative.’” Because “[t]he Executive’s use of tariffs qualifies as a decision of vast economic and political significance, so the Government must ‘point to clear congressional authorization’” for its actions. The Federal Circuit concluded that there was no such authorization in the IEEPA.
Nor can the conservative justices draw a distinction between the powers of the president and the authority of agencies, saying that the major questions doctrine applies only to the latter. In a series of recent rulings on the emergency docket involving removal of government officials – such as Trump v. Wilcox and Trump v. Harris – the six conservative justices have made clear that they accept the unitary executive theory, or the idea that the president has control over the entire executive branch. In Trump v. United States, the court stated (quoting a previous case): The president is “the only person who alone composes a branch of government.” In light of this, there cannot be a meaningful distinction between the powers of the president and the powers of the agencies.
Perhaps the conservative justices can try and say that these principles don’t apply to matters concerning foreign policy. In his filing in the Supreme Court, Solicitor General D. John Sauer says that the major questions doctrine has not been applied “in the national security or foreign policy contexts, because the canon does not reflect ordinary congressional intent in those areas.”
But, to be consistent, the conservative justices should balk at that argument. The text of the Constitution itself and its original meaning are clear: Congress has the power with regard to tariffs. Article I, Section 8 of the Constitution states that “[t]he Congress shall have power to lay and collect taxes, duties, imposts and excises,” as well as to “regulate commerce with foreign nations.” As Gorsuch argued in his recent opinion in Federal Communications Commission v. Consumers’ Research, the power to tax – and tariffs are a tax – rests solely with Congress.
Of course, the conservative justices can abandon their textualism, their major questions doctrine, and their originalism and uphold Trump’s tariffs. In doing so, they would be making clear that they follow these doctrines only when reviewing the actions of a Democratic president, as they did during the Biden administration. But then they would be showing that their jurisprudence is not principled, and is instead just rhetoric to support conservative results when it supports the conclusions they want to reach.
Besides its economic significance, that is what makes the tariffs case so fascinating in the Supreme Court. Will the conservative justices adhere to what they have said and held recently, or will they just rubber stamp whatever Trump does?

It is not a clearcut case: the Heritage Foundation supports the government's position, the Federalist Society opposes it.
As of yesterday, Polymarket's betting line gives a slight edge to the government's case failing: you need bet $.48 to win a dollar if you think the tariffs will be upheld, whereas a decision striking the tariffs require $.53.
Get ready to lose Free Traitors.
If 47 loses in SCOTUS, P. Navarro said on Maria this AM that they have a Plan B - which they are keeping quiet until after SCOTUS rules.
I’d say just a plan B is not enough, because I know the left is united in hate.
Ok yeah written by Erwin Chemerinsky. LOL. You just know it is going to be an honest evaluation of the constitutional issues at play.
I disagree with this point. The consequences will be limited, and these tariffs will be no more consequential than a Trump executive order renaming the “Gulf of Mexico” to the “Gulf of America.”
I wouldn’t be surprised if the Trump administration loses this case by a 9-0 margin in the Supreme Court.
Your complete misunderstanding of global economics never ceases to amaze.
Also all of you FreeTraitors better to get ready to lose. Your globalist/marxist experiment is about to be put down .
Why, if it isn’t Johnny One-Note, endlessly spewing the same tired insults.
If you are so confident, you should really visit that gaming site I mentioned. You’ll double your money if these tariffs are upheld. You’re welcome!
Way too many people on the right are ignoring the bolded distinction because they support tariffs.
I do think there is another potential question - even if SCOTUS were to find that the IEEPA authorizes these tariffs - though I don't think they will - they could then argue that it was such a complete delegation of legislative authority so as to be unconstitutional on that ground.
I think it goes down at least 6-3. But, the President can then ask Congress to pass those same tariffs, and perhaps it will.
And your expertise is …?
I wouldn't either.
Exactly. I support tariffs in principle, but I also understand the bolded distinction you posted.
I watched the USA de industrialize over the last 30. To be an expert just drive around and look at all the dead factory towns. I am worried if you traitors lose we will see violence from that evil faction.
Trump and America will win. Will you globalists Free Traitors get violent when you lose? After all you Free Traitors are part of the political left wing.
Driving around dead factory towns does not make you a Constitutional authority.
“I am worried if you traitors lose we will see violence from that evil faction.”
Who’s the “evil faction”?
lol but the left loves taxes right🤔😎
Your "FreeTraitor" schtick proves one thing - that when it comes to the Constitution, you are as results-oriented as the worst of the left. Right at home with the Wise Latina and KBJ.
Whether these tariffs are a good idea or not is irrelevant. What matters is whether: 1) they are authorized by the IEEPA, and 2) the IEEPA - if interpreted that broadly - is an unconstitutional delegation of legislative authority.
Whether or not the tariffs are good economic policy is a non-issue.
By that thinking are not regulations that increase costs also “taxes”🤔🤔🤔🤔
Something dims also love😂
You and all Free Traitors are part of the left. The left has been getting violent lately. Free Traitors may become unhinged when you lose.
