When the Supreme Court steps into a tariff fight, it is never just about shipping containers, customs forms, or who pays more for imported machine parts. It is also about something very American: who gets to make the rules when money, power, and politics all show up at the same dinner table. And in the modern trade era, that dinner table has been loud.

The latest clash over executive tariff power turned into one of the biggest separation-of-powers battles in recent years. At the center of the dispute was a simple but explosive question: can a president use emergency powers to slap sweeping tariffs on imports from nearly the whole world, or does that kind of move still belong to Congress unless lawmakers clearly say otherwise?

The Supreme Court’s answer was a legal version of “nice try, but no.” In a closely watched decision, the justices concluded that the International Emergency Economic Powers Act, better known as IEEPA, does not authorize the president to impose tariffs. That ruling was not a blanket ban on presidential tariffs, and it did not magically end U.S. trade fights. But it did draw a bright line around one especially aggressive theory of executive power.

For businesses, consumers, lawmakers, and trading partners, the message was unmistakable: tariffs are powerful tools, but the White House cannot simply reach into the emergency toolbox and pull out a global tax wand whenever it feels inspired. The Constitution, as it turns out, is still not a suggestion box.

Why This Case Mattered So Much

Tariffs may sound like the sort of topic best left to economists, lobbyists, and the one uncle who says “supply chains” at every holiday meal. But they matter because they function as taxes on imported goods. That means they affect pricing, sourcing, production, investment, and consumer costs all at once. They can protect certain domestic industries, pressure foreign governments, or raise revenue. They can also create serious disruption when rolled out quickly and broadly.

Under Article I of the Constitution, Congress holds the power to lay duties and regulate commerce with foreign nations. Over time, Congress has delegated parts of that authority to presidents through specific statutes. That is why modern presidents have real tariff tools. But those tools are not limitless, and they do not all work the same way.

Some laws allow tariffs after investigations into national security risks. Others are tied to unfair trade practices or import surges that injure domestic producers. Those statutes have conditions, procedures, timelines, and triggers. IEEPA is different. It is an emergency law enacted in 1977 to let presidents deal with unusual and extraordinary foreign threats during declared national emergencies. It has traditionally been associated with sanctions, blocked assets, and financial restrictions, not broad-based tariff policy.

That difference became the whole ballgame.

How the Tariff Fight Reached the Supreme Court

The White House Took a Very Expansive View of Emergency Power

In 2025, the Trump administration used IEEPA to support two major categories of tariffs. One set targeted goods from Canada, Mexico, and China in response to drug-trafficking and fentanyl-related concerns. Another set, often described as “reciprocal” tariffs, imposed a baseline tariff on imports from virtually all trading partners, with higher rates for some countries. In practical terms, this was not a narrow trade adjustment. It was a sweeping claim of presidential power over import taxation.

That claim quickly triggered lawsuits from businesses and states. Small companies argued that the tariff swings were not just inconvenient but potentially devastating. Importers claimed they were being forced to operate in a fog of abrupt cost spikes, changing rates, and uncertain supply decisions. States argued that the administration had stretched an emergency statute beyond anything Congress intended.

Lower Courts Were Already Uncomfortable

The first major warning shot came from the U.S. Court of International Trade, which ruled that most of the IEEPA tariffs exceeded presidential authority. A federal district judge in Washington reached a similar conclusion in a separate case involving Learning Resources and hand2mind, two family-owned businesses that said the tariffs would cost them staggering sums. The Federal Circuit later affirmed the core lower-court reasoning in a divided decision, although it temporarily kept the tariffs in place to allow Supreme Court review.

By the time the justices agreed to hear the dispute, the case had become bigger than trade. It had become a referendum on whether vague statutory language can be stretched into a license for open-ended economic statecraft.

What the Supreme Court Decided

On February 20, 2026, the Supreme Court held 6-3 that IEEPA does not authorize the president to impose tariffs. Chief Justice John Roberts announced the judgment, and the majority rejected the idea that the statute’s power to “regulate” importation quietly includes the power to impose sweeping tariffs of enormous scope, duration, and economic significance.

That conclusion matters because the government’s theory was breathtakingly broad. If accepted, it would have allowed the president to impose tariffs on nearly any product, from nearly any country, at nearly any rate, for nearly any length of time, so long as the White House linked the action to a declared foreign threat. The Court was not persuaded that Congress had handed over that kind of authority through a few general words in an emergency statute.

In other words, the justices were not buying the legal equivalent of “trust me, it’s in the fine print.”

A Strange but Important Majority

The 6-3 lineup was notable. The majority brought together justices from both ideological wings of the Court, though not all of them arrived at the same reasoning. Some emphasized ordinary statutory interpretation. Others leaned harder into the major questions doctrine, which says courts should be skeptical when the executive claims vast power without clear congressional authorization.

That internal disagreement matters to lawyers and judges because it could shape future fights over administrative power. But for everyone else, the bottom line was simple: the Court agreed that this statute did not clearly authorize this tariff program.

The Dissent Saw It Differently

Justice Brett Kavanaugh, joined by Justices Clarence Thomas and Samuel Alito, dissented. Their basic point was that tariffs are a traditional tool for regulating imports, and historical practice shows Congress has long delegated tariff authority to presidents in different ways. The dissent also argued that if IEEPA permits embargoes and quotas, it makes little sense to say it forbids the lesser step of imposing a tariff.

That argument was not frivolous. In fact, it explains why the case was so consequential. This was not a goofy lawsuit built on a technical typo. It was a serious dispute over how broadly to read presidential power in the foreign affairs arena. The majority simply decided that tariffs, because of their constitutional and economic importance, require clearer permission than IEEPA provides.

Why the Court Drew the Line

Tariffs Are Not Just Another Regulatory Knob

One reason the Court was skeptical is that tariffs are not merely administrative housekeeping. They are taxes on imports. They raise revenue, alter prices, and shift bargaining power across the economy. During oral arguments, several justices pressed the point that taxation has historically been a core congressional power. That constitutional background made the administration’s reading of IEEPA feel like a mismatch.

The issue was not whether tariffs can ever be used by a president. They can. The issue was whether Congress had clearly authorized this president to do this under this statute. The Court said no.

The “Major Questions” Shadow Was Hard to Ignore

Even before the ruling came down, the justices appeared uneasy with the scale of the administration’s theory. During oral argument, members of the Court asked whether Congress could really have intended to transfer such sweeping tariff power through language that never specifically mentions tariffs. That concern tracks the major questions doctrine: when the executive claims power of vast economic and political significance, courts expect Congress to speak clearly.

This case fit that mold almost too neatly. Tariffs touching most U.S. trading partners are not obscure policy tweaks. They are headline-making, market-moving, globally felt actions. A president claiming that kind of authority through an emergency law better have a crystal-clear statutory invitation. The Court found no such invitation.

Foreign Affairs Power Still Has Borders

The administration also argued that foreign affairs and national emergency contexts call for broad presidential flexibility. That argument has real force, because presidents do receive substantial deference in external affairs. But deference is not a blank check. The Court made clear that foreign policy relevance does not erase the need for legal authority. Put differently, the White House does not get extra statutory words just because another country is involved.

What the Ruling Does Not Mean

This is the part where trade lawyers clear their throats and say, “Actually…” And they are right to do so.

The Supreme Court did not say presidents can never impose tariffs. It did not invalidate all Trump-era trade actions. It did not wipe out Section 232 tariffs tied to national security, Section 301 tariffs tied to unfair trade practices, or safeguard actions under Section 201. Those authorities remain available, and some are politically potent.

That means the decision was a major loss for one tariff strategy, not the end of tariff politics altogether. If anything, it may push future administrations to rely more heavily on statutes with clearer procedures and more explicit trade language. That could make the process slower and narrower, but not necessarily gentler.

What Happens Next for U.S. Trade Policy

Refunds Could Be the Next Headache

Once the Court ruled, attention quickly shifted from legal theory to a brutally practical question: who gets their money back? Companies that paid the now-invalid IEEPA tariffs began pressing for refunds, and lower courts moved into the messy business of sorting out remedies. That process is likely to be technical, time-consuming, and expensive. Customs law is not famous for being breezy.

For importers, a refund is welcome news. But it is not a time machine. A business that delayed hiring, canceled orders, rerouted inventory, or raised prices cannot fully recover from those choices just because money arrives later. That is one reason so many companies cared not just about tariff levels, but about legal predictability.

The White House Still Has Other Paths

Even critics of the IEEPA strategy have acknowledged that the executive branch still possesses substantial tariff authority under other laws. Section 232, for example, can support tariffs tied to national security findings. Section 301 can be used after trade investigations into unfair foreign practices. Other, less commonly discussed provisions may also offer temporary or targeted options.

So the legal vehicle may change, but the political appetite for tariffs may not. That is why this ruling feels less like a final chapter and more like a rewrite of the playbook.

Why This Case Matters Beyond Tariffs

The tariff decision matters because it reminds Washington that constitutional structure still counts even during noisy, high-pressure economic fights. Congress cannot casually hand over foundational fiscal power through fuzzy language. Presidents cannot turn emergency statutes into universal economic toolkits. And courts, when pushed, may still insist that the branches stay in their lanes.

That is the broader significance of this case. It is about who decides major national policy, especially when that policy looks suspiciously like taxation wrapped in foreign-policy packaging. The Supreme Court’s answer was that the president may act boldly, but only when Congress has clearly authorized the move.

That may sound dry, but it is actually one of the liveliest ideas in constitutional law: power is real, but permission matters.

Real-World Experiences: What Executive Tariff Power Has Felt Like

For people who do not spend their mornings reading customs bulletins for fun, the tariff fight may seem abstract. In practice, though, executive tariff power has been experienced less as a constitutional seminar and more as a rolling stress test.

For small importers, the experience has often been pure whiplash. A shipment quoted one week can become dramatically more expensive by the time it lands, and margins that looked healthy on paper can turn into sad little puddles by the time customs duties are calculated. Businesses selling toys, components, home goods, apparel, and specialty products have had to make daily decisions about whether to absorb costs, raise prices, delay orders, or search for new suppliers. None of those choices is cheap, and none comes with a guarantee.

Customs brokers and trade compliance teams have felt the chaos in a different way. When tariffs change quickly, they are the ones racing to interpret notices, reclassify entries, explain new rules to confused clients, and answer the world’s least romantic question: “So what exactly do we owe now?” Trade policy may be announced with patriotic fanfare, but it is implemented through paperwork, coding, and a lot of people quietly muttering at spreadsheets.

Manufacturers have also lived through the contradiction at the heart of tariff policy. Some producers benefit from higher barriers against foreign competition. Others get slammed because their own inputs become more expensive. A steel tariff might help one company and hurt another two warehouses over. An electronics tariff may protect one domestic niche while making other U.S. businesses less competitive downstream. That is why tariff debates never stay tidy for long. They start with slogans and end with supply-chain maps.

Consumers, meanwhile, experience tariff power in the most familiar way possible: prices that feel sneakily heavier. Not every tariff shows up immediately on a store shelf, and not every company passes through every cost increase. But over time, duties on imports push against retail pricing, inventory choices, and product availability. That is especially true when tariffs are broad, fast, and uncertain.

Even the legal aftermath has its own odd emotional texture. Refunds sound like happy news, and in many cases they are. But for companies that spent months planning around those tariffs, a future refund can feel less like a victory lap and more like reimbursement for a fire drill that never should have happened. Cash flow was strained. Orders were missed. Strategies were rewritten. Confidence took a hit.

That is the lived experience behind the Court’s abstract debate over executive tariff power. It is not just about legal doctrine. It is about whether businesses can plan, whether consumers can budget, and whether the rules of trade arrive through stable law or surprise announcements. For many companies, that distinction is the difference between managing risk and simply bracing for impact.

Conclusion

The Supreme Court’s tariff ruling did not end America’s fascination with tariffs, and it definitely did not end the political temptation to use them as leverage, theater, or both. What it did do was remind the country that even aggressive trade policy needs a lawful foundation. Emergency power is powerful, but it is not infinitely elastic.

In the end, the justices did not say tariffs are forbidden. They said the president must use the right statute, and Congress must speak clearly when it wants to hand over authority this significant. That is a serious constitutional principle wrapped in a very modern policy fight.

So yes, this case was about tariffs. But it was also about a deeper rule of American government: the biggest economic powers cannot be improvised out of broad language and bold attitude alone. In Washington, swagger may move markets for a day. Clear statutory authority lasts longer.

Note: This article is an original, publication-ready rewrite based on real court developments and reputable U.S. reporting.

For a case about tariffs, customs statutes, and separation of powers, this one had unusual star power. When the Supreme Court agreed to fast track the appeal over President Donald Trump’s tariff regime, it instantly turned a trade-law fight into one of the most important executive-power stories in the country. Suddenly, importers, retailers, economists, and constitutional lawyers were all staring at the same question: can a president use an emergency powers statute to slap sweeping tariffs on goods from around the world?

That question was not just academic. It sat at the center of a tariff regime that affected trade flows, business planning, consumer prices, government revenue, and America’s relationship with trading partners. In plain English, the Court was being asked whether emergency authority could become a kind of all-purpose tariff machine. That is a massive legal question, a massive economic question, and, frankly, the sort of thing that makes even a boring spreadsheet start sweating.

The Supreme Court’s decision to move quickly mattered almost as much as the case itself. Instead of letting the dispute drift through the normal calendar, the justices put it on an accelerated track, signaling that the stakes were too high for a slow-motion legal stroll. That fast-track move told businesses one thing immediately: relief, reversal, or more chaos was coming sooner than usual.

Why This Appeal Mattered So Much

At the center of the dispute was the Trump administration’s use of the International Emergency Economic Powers Act, or IEEPA, to justify broad tariffs. IEEPA is best known as a sanctions and emergency-powers law, not as a general tariff statute. That distinction is not a technical footnote. It is the whole ballgame.

The Constitution gives Congress the power to lay and collect taxes, duties, imposts, and excises. Tariffs are import taxes. Presidents have long exercised trade authority, but usually because Congress spelled out that authority in specific trade laws with standards, limits, or procedures attached. That is why the legal challenge to Trump’s tariff regime was so explosive: critics argued the administration was trying to pull a freight train through a doorway marked “emergency powers,” then insisting the doorway had always been that big.

Businesses challenging the tariffs argued that IEEPA does not mention tariffs and had never before been used by a president as the legal basis for sweeping import taxes. The administration countered that the statute’s power to “regulate” importation was broad enough to include tariffs. Lower courts were not persuaded, and once those losses piled up, the issue was headed toward the Supreme Court at full speed.

What SCOTUS Actually Did

When the Supreme Court agreed to hear the case on a fast-track basis, it did more than accept another politically charged appeal. It consolidated the key tariff challenges, imposed an unusually compressed briefing schedule, and set the matter for argument in the first week of the November 2025 sitting. In Supreme Court time, that is basically the legal equivalent of double espresso.

The accelerated schedule meant the Court was not content to let the dispute simmer until late in the term. That was important because the tariffs remained in effect while the litigation continued. Every additional month mattered. Importers were paying duties, businesses were making pricing decisions, and the federal government was collecting large sums of revenue while the legality of the whole setup remained under a cloud.

In practical terms, the fast track served two purposes. First, it reduced uncertainty for markets and businesses. Second, it put a spotlight on the institutional stakes. The Court understood this was not a niche trade spat buried in customs codes. It was a headline case about whether presidents can transform emergency language into broad economic policymaking authority.

How the Tariff Regime Reached the High Court

The path to the Supreme Court was messy, fast, and full of legal whiplash. Trump imposed tariffs tied to national-emergency declarations involving drug trafficking and trade imbalances. The challenged measures included tariffs on China, Mexico, and Canada, as well as a broad regime that put a baseline 10% tariff on imports from nearly all trading partners, with higher rates for some countries.

That regime triggered lawsuits from small businesses, import-reliant companies, and states. One challenge involved the Learning Resources plaintiffs, small businesses that sued in Washington. Another came from V.O.S. Selections and other challengers in the Court of International Trade. These were not abstract plaintiffs hunting for a constitutional theory to frame on the wall. They were businesses saying, in effect, “Our invoices are on fire, and we would like someone to explain why.”

Lower courts ruled against the administration, concluding that IEEPA did not authorize tariffs of this breadth. The Federal Circuit, sitting en banc, became especially important because it treated the issue as one involving no clear congressional authorization for tariffs of such sweeping economic and political significance. At the same time, the courts stayed their rulings temporarily, allowing the tariffs to remain in place long enough for the administration to seek Supreme Court review.

That temporary stay was crucial. Without it, the tariff structure could have begun unraveling before the justices even decided whether to take the case. Instead, the administration preserved the regime long enough to argue that the Supreme Court needed to act quickly to prevent legal and economic disruption.

The Core Legal Question: Can Emergency Power Become Tariff Power?

This was the heart of the case. The administration argued that IEEPA’s authorization to regulate importation gave the president enough room to impose tariffs in response to national emergencies. From that perspective, tariffs were simply one regulatory tool among several available in a foreign-affairs and national-security context.

The challengers said that reading stretched the law beyond recognition. Their argument was straightforward and potent: if Congress wanted to give the president authority to impose tariffs of unlimited scope, amount, and duration, Congress knew how to say so. Instead, IEEPA did not mention tariffs at all. That absence mattered even more because tariff power is traditionally tied to Congress and because other trade statutes include specific caps, procedures, and limits.

This is where the Supreme Court’s “major questions” doctrine hovered over the case like a very stern hall monitor. That doctrine generally says that when the executive branch claims authority over issues of vast economic and political significance, courts expect clear authorization from Congress. The challengers argued that if the doctrine applies anywhere, it should apply here. After all, a president asserting the power to tax imports from virtually any country, at potentially huge scale, is not asking for a minor administrative footnote. That is a major power.

The Court’s conservative justices had previously used that doctrine to strike down expansive executive actions by Democratic administrations. So the tariff case carried an additional layer of intrigue: would the same principle be applied when the executive overreach claim involved a Republican president and a signature trade agenda?

Why Businesses, Consumers, and Markets Were Watching Closely

Tariffs are often discussed like they are abstract foreign-policy levers. In reality, they show up in budgets, shipping plans, contracts, inventory decisions, and retail prices. A business importing toys, wine, electronics, machinery, or household goods does not experience tariffs as a grand theory of statecraft. It experiences them as higher landed costs, thinner margins, and more uncomfortable meetings with finance teams.

That is why the fast-track appeal mattered well beyond Washington. If the administration won, the president would emerge with an extraordinarily powerful tool for reshaping trade relationships. If the challengers won, importers might eventually seek refunds on enormous sums already collected under the tariff regime. Either outcome had serious implications for commerce.

There was also a consumer angle. Businesses often absorb some tariff costs, but not all of them. Higher import costs can eventually move through supply chains and into prices. Economists and business groups repeatedly warned that the tariff fight was not just about constitutional theory. It was also about what families pay, what companies hire, and how firms decide where to source goods.

And importantly, not every Trump tariff was wrapped into this exact dispute. Tariffs imposed under separate statutes, such as other trade authorities, were not automatically swept into the same legal basket. That meant the case was huge, but not total. The broader tariff story still had other chapters waiting in the wings.

Why the Fast Track Was Such a Big Deal

Supreme Court cases usually move at a measured pace. Briefing takes time. Amicus filings pile up. Oral arguments arrive months later. Decisions often come at the end of the term. That is normal. But nothing about this case felt normal.

The justices’ decision to move quickly suggested they recognized two realities. First, the legal uncertainty was too disruptive to leave hanging for a full term. Second, the issue was central to the administration’s economic agenda and could not sensibly be treated like a sleepy dispute over filing deadlines and dusty precedent.

The speed also mattered symbolically. Fast-tracking did not mean the Court endorsed the tariffs. It meant the Court accepted that the question was urgent. In a term already filled with high-stakes clashes over presidential power, the tariff case stood out because it blended constitutional structure, trade policy, and real money on a scale that made ordinary litigation look like small claims court with fancier shoes.

As it turned out, the fast-track order truly did matter. The Court heard argument on November 5, 2025, and instead of waiting until late June 2026, it issued a major ruling on February 20, 2026. That is still not instant, but by Supreme Court standards, it counts as moving with purpose.

How the Story Ultimately Played Out

The fast-tracked case eventually produced a major result. On February 20, 2026, the Supreme Court held that IEEPA does not authorize the president to impose tariffs. In other words, the challengers won the core legal argument. The Court concluded that the administration’s reading of “regulate importation” could not support tariffs that were, in the Court’s view, effectively unbounded in scope, amount, and duration.

That ruling mattered for at least three reasons. First, it rejected one of the boldest claims of executive trade authority in modern American history. Second, it reinforced the idea that Congress must speak clearly when delegating massive economic power to the president. Third, it opened the door to a sprawling and messy refunds fight over the tariff money already collected.

That refunds issue was not a side quest. It was a looming fiscal and logistical headache. Analysts later estimated that more than $175 billion in tariff revenue could be subject to refund claims. The Court did not hand out a neat, one-page answer for how that process should unfold. Instead, the issue flowed back into the trade-law system, where businesses large and small began weighing how to recover money they had paid under a regime the Court ruled unlawful.

So yes, the fast-track appeal mattered when it was granted. But it mattered even more in hindsight, because it accelerated a decision that reshaped the legal understanding of presidential tariff authority.

What Businesses Learned From the Tariff Fight

The first lesson was brutal but clear: legal authority matters, even when a policy has already changed how the market behaves. Plenty of companies had no choice but to operate as if the tariffs were fully stable while also knowing the legal foundation might crack beneath them. That is not strategy; that is expensive improvisation.

The second lesson was that trade policy now moves on at least three tracks at once: politics, economics, and litigation. If you only watch one of those tracks, you can get flattened by the other two. A tariff may be announced as foreign policy, defended as economics, and ultimately destroyed as unlawful administration.

The third lesson was about timing. In trade law, months matter. The difference between a ruling in February and a ruling in June can mean billions more collected, hundreds more contract disputes, and thousands more pricing decisions locked into place. The Supreme Court’s fast-track order recognized that time itself was part of the case.

On the Ground: What the Tariff Battle Felt Like

Across the trade community, the experience of this case was less dramatic courtroom theater and more survival by spreadsheet. For importers, customs brokers, and finance teams, the tariff regime did not arrive as a neat constitutional seminar. It arrived as an avalanche of daily calculations. A shipment that looked profitable on Monday could look shaky by Friday if duty assumptions changed, a supplier altered terms, or a legal update suggested the tariff base might not hold.

Small businesses felt this especially hard. A giant multinational can spread tariff pain across product lines, financing channels, and continents. A smaller importer often cannot. For a toy company, a wine importer, or a specialty-goods distributor, the math was painfully direct: higher import taxes meant lower margins, harder price conversations, delayed hiring, and inventory decisions made with very little confidence. Owners were not sitting around debating the finer points of statutory interpretation over lattes. They were deciding whether to pass costs on to customers, eat losses, or postpone expansion plans they had spent years building.

Customs professionals had their own version of the headache. They had to advise clients in real time while the legal ground kept shifting. Tariffs stayed in place, then seemed vulnerable, then stayed in place again during appeal, then faced a fast-tracked Supreme Court review. Clients wanted certainty, and the honest answer was usually some variation of, “We know what Customs is collecting today, but tomorrow’s legal theory may still be under construction.” No one enjoys saying that for a living, even if they bill by the hour.

Then there were the executives and controllers staring at cash flow. Every tariff payment was not just an accounting entry. It was money that could have gone to payroll, equipment, marketing, or debt reduction. As the court fight intensified, some businesses had to start treating tariff costs like contested cash: money gone for now, possibly recoverable later, but unavailable when they actually needed it. That kind of uncertainty makes planning feel like building a house during an earthquake and hoping the blueprints remain valid.

Consumers, meanwhile, usually experienced the whole thing indirectly. They saw price increases, smaller promotions, delayed restocks, or brands quietly changing product mixes. Most shoppers never read a Supreme Court docket, and understandably so. But they live with the consequences when trade policy ripples through supply chains. The tariff fight showed how quickly a legal dispute in Washington can turn into a practical problem in a checkout aisle.

Even after the eventual ruling against the tariffs, many businesses were not exactly popping champagne. Winning in court did not immediately erase months of uncertainty or magically return money overnight. Refund questions, compliance costs, and the possibility of new tariff approaches all remained on the table. In that sense, the real experience of the case was not triumph or defeat. It was fatigue. The kind that comes from running a business while public policy keeps changing the rules mid-game and then asking whether you saved the receipts.

Conclusion

The Supreme Court’s decision to fast track the appeal of Trump’s tariff regime was a signal that the justices understood the scale of the dispute. This was never just a fight about customs duties. It was a fight over who gets to wield one of the government’s most economically consequential tools, and how clearly Congress must speak before the president can use it.

In the end, the fast-track order did what fast-track orders are supposed to do: it moved a nationally significant question toward resolution before uncertainty metastasized further. The later ruling against the IEEPA tariffs confirmed that the case was every bit as consequential as it looked on the day the Court sped it up. For businesses, consumers, and anyone interested in the boundary between executive ambition and statutory reality, the lesson is plain. Tariffs may be announced with bravado, but they still have to survive the text of the law. And in this case, the law had the last word.
