“The power to levy taxes on imports belongs to Congress — not to the President acting alone under emergency law.” — US Supreme Court, February 20, 2026
On February 20, 2026, the United States Supreme Court delivered the biggest legal defeat of Donald Trump’s second term — striking down his sweeping global tariffs in a landmark 6-3 ruling. The court held that the International Emergency Economic Powers Act (IEEPA) does not authorise the President to impose tariffs, a power that belongs exclusively to Congress under the US Constitution.
Trump’s explosive response, calling justices “fools and lapdogs” and accusing the court of foreign influence, set off a constitutional firestorm. His immediate announcement of a new 10% global tariff under a different law — and his reassurance that the India trade deal remains on track — make this one of the most consequential international affairs events of 2026.
📜 Trump’s Tariffs & IEEPA: The Background
When Donald Trump returned to the White House for his second term, trade policy became one of his most aggressive instruments. He invoked the International Emergency Economic Powers Act (IEEPA) — a 1977 law granting the President broad power to regulate international commerce during a declared national emergency — to impose sweeping import tariffs on goods from countries across the world, framing America’s trade deficit as a national emergency.
No previous president had used IEEPA to impose tariffs at this scale or scope. The move was immediately challenged in courts, with plaintiffs arguing that Congress — not the President — holds the constitutional power to levy taxes and duties on imports under Article I of the US Constitution.
Think of IEEPA like an emergency toolkit. It was designed for sanctions and asset freezes during genuine crises — not to give a president the power to unilaterally rewrite the entire global trading system. That’s like using a fire extinguisher to repaint your house.
⚖️ The Supreme Court Ruling: What the Court Decided
The Supreme Court’s majority held a clear constitutional position: IEEPA does not authorise the President to impose tariffs. The power to levy taxes and duties on imports belongs to Congress under Article I of the US Constitution. A presidential declaration of national economic emergency does not transfer that legislative authority to the executive branch.
The ruling was the most significant judicial rebuke of Trump’s second-term agenda. Crucially, the 6-3 conservative court — shaped by Trump’s own three first-term appointees (Neil Gorsuch, Brett Kavanaugh, Amy Coney Barrett) — ruled against him, with justices crossing partisan lines. Trump had publicly expected his nominees to support his position.
Vote Breakdown: The Supreme Court currently has a 6-3 conservative majority. Yet the majority against Trump’s tariffs included both conservative AND liberal justices — only three voted in Trump’s favour. This bipartisan nature of the ruling is itself a key exam fact.
| Aspect | Trump’s Argument | Court’s Ruling |
|---|---|---|
| Legal Basis | IEEPA grants president power to act during national emergency | IEEPA does not cover tariff imposition |
| Constitutional Authority | Trade deficit = national emergency justifying executive action | Tariff power belongs to Congress (Article I) |
| Precedent | Presidents have used IEEPA broadly since 1977 | No prior president used it for tariffs at this scale |
| Separation of Powers | Emergency powers justify bypassing Congress | Congress cannot hand over core legislative powers to executive |
🌑 Trump’s Extraordinary Response: Attacking the Court
Trump’s response to the ruling was, by any historical measure, extraordinary. At a White House press conference flanked by Treasury Secretary Scott Bessent and Commerce Secretary Howard Lutnick, Trump launched an unprecedented attack on the Supreme Court — including justices he personally appointed.
He called the ruling “a disgrace to our nation”, described majority justices as “fools and lapdogs,” accused the court of being “swayed by foreign interests” without evidence, and said the ruling was an “embarrassment to their families” — targeting his own nominees Gorsuch and Barrett by name. Vice President JD Vance called the ruling “lawlessness from the court” — a framing that constitutional scholars called an alarming inversion of the constitutional order.
When a sitting president publicly accuses the Supreme Court of corruption and foreign influence — without evidence — what does that do to the judiciary’s institutional legitimacy? Even Speaker Mike Johnson and Senator Mitch McConnell distanced themselves from Trump’s attack, signalling unease within his own party. The norm of judicial independence, once eroded, is far harder to rebuild than any tariff rate.
📌 The Section 122 Workaround: A New 10% Global Tariff
Within the same press conference, Trump announced he would sign an executive order imposing a 10% global tariff on all imports under an entirely different legal authority — Section 122 of the Trade Act of 1974. This provision grants the President authority to impose a temporary tariff of up to 15% to address a large and serious balance-of-payments deficit.
However, Section 122 comes with a critical constraint: the tariff can last a maximum of 150 days without Congressional approval. After 150 days, Congress must affirmatively extend it, or the tariff expires — setting up a major political battle around July 2026. Treasury Secretary Bessent stated that combined with tariffs under Sections 232 (national security) and 301 (unfair trade practices) — unaffected by the ruling — total tariff revenue in 2026 would be “virtually unchanged.”
Don’t confuse the three tariff authorities: IEEPA (struck down for tariffs), Section 122 (new 10% tariff — max 150 days), Section 232 (national security — still valid), Section 301 (unfair trade practices — still valid). Exams may test which law was struck down vs. which remains in force.
⚖️ Constitutional Stakes: Why This Ruling Goes Beyond Trade
At its core, this ruling is about separation of powers — the constitutional architecture dividing authority between Congress, the President, and the judiciary. The court reinforced the non-delegation doctrine: the principle that Congress cannot simply hand over its core legislative powers to the executive. The Constitution gives Congress the power to levy taxes and regulate commerce; Congress may give the President limited authority in specific circumstances, but cannot effectively abdicate its legislative role through a blank-cheque emergency powers law.
The ruling also raises the future of IEEPA itself. Used since 1977 for sanctions and asset freezes, its broader scope is now live for litigation. Expect significant legal and legislative battles on IEEPA’s limits in the coming years. This ruling draws a clear constitutional line that will outlast the Trump administration.
🌍 The India Angle: What This Means for India-US Trade
Despite the constitutional turmoil, Trump confirmed explicitly at the same press conference: “The India deal is on.” He cited India’s decision to reduce purchases of Russian oil at his request as evidence of bilateral goodwill. India and the US had reached an interim trade framework in the weeks before the ruling, and India-US trade officials were set to hold three days of talks beginning February 23 to finalise the legal structure for the interim pact.
Commerce Minister Piyush Goyal confirmed the interim pact is expected to take effect in April 2026. Notably, India signed the Pax Silica declaration on the same day as the Supreme Court ruling — a strategic technology partnership signal covering semiconductors, AI, and defence — reinforcing that the India-US relationship is advancing on multiple tracks simultaneously, insulated from Trump’s domestic political battles.
The new 10% Section 122 tariff does apply to all countries including India. However, the 150-day time limit, India’s interim trade framework, and the export basket composition (pharmaceuticals, IT services, gems, engineering goods) all moderate the impact. India’s strategic calculation appears sound: anchor long-term ties in technology and security cooperation, accept some short-term tariff friction, and position India as an indispensable US partner in the Asia-Pacific.
India’s simultaneous pursuit of a trade deal AND a strategic technology declaration on the day of the US constitutional crisis reflects the concept of “strategic autonomy with calibrated alignment.” How does India navigate great power competition while protecting its own economic interests? This is a rich essay topic combining diplomacy, trade, and constitutional governance.
