What Happened
- The US Supreme Court ruled 6–3 on February 20, 2026, that tariffs imposed by the Trump administration under the International Emergency Economic Powers Act (IEEPA) are unconstitutional — the "reciprocal" tariffs on most US trading partners and tariffs on China, Canada, and Mexico linked to immigration/opioid emergencies were struck down.
- Chief Justice Roberts applied the "major questions doctrine" to hold that IEEPA's text did not explicitly authorise the imposition of tariffs, a core congressional power.
- In response, the Trump administration announced new national security investigations under Section 232 of the Trade Expansion Act of 1962 and new Section 301 investigations under the Trade Act of 1974 against most major trading partners.
- A new 10% global tariff was also imposed under Section 122 of the Trade Act of 1974 (effective June 24), with various carve-outs.
- Tariffs already in place under Section 232 (steel and aluminium) and Section 301 (China-specific) remain in force as they derive from separate statutory authority unaffected by the ruling.
Static Topic Bridges
International Emergency Economic Powers Act (IEEPA) — What It Is and Its Limits
IEEPA, enacted December 28, 1977, is a US federal law authorising the President to regulate international commerce after declaring a national emergency in response to an "unusual and extraordinary threat" with its source wholly or substantially outside the US. It succeeded the Trading with the Enemy Act of 1917 (TWEA), carving out peacetime emergency economic powers for the President.
- Enacted: December 28, 1977 (50 U.S.C. §§ 1701–1708)
- Predecessor: Trading with the Enemy Act, 1917 (war-time powers)
- Powers granted: President can investigate, regulate, or block financial transactions, trade, and property transfers involving foreign nationals or entities
- Traditional uses: Sanctions (Iran, Russia, North Korea), asset freezes, blocking transactions with designated entities — NOT tariff-setting
- Trump's novel use: invoked IEEPA to impose sweeping country-specific import tariffs (20–145%), arguing trade deficits constituted a national emergency — a significant expansion of prior usage
- Supreme Court ruling (February 20, 2026): 6–3; Chief Justice Roberts applied the "major questions doctrine" — extraordinary executive claims to broad authority require explicit Congressional authorisation; IEEPA's text does not explicitly grant tariff power; struck down all IEEPA-based tariffs
Connection to this news: The ruling curtailed the President's most sweeping tariff authority but did not eliminate all trade-restriction tools — it forced the administration to pivot to other, more established statutory mechanisms.
Alternative US Tariff Authorities — Section 232, Section 301, Section 201, Section 122
The US has several distinct statutory authorities for imposing trade restrictions, each with different legal thresholds, procedural requirements, and scope. The Supreme Court's ruling on IEEPA does not affect these.
Section 232 (Trade Expansion Act, 1962): - Authority: President can impose tariffs or quotas if imports threaten national security - Process: Commerce Department investigation (up to 270 days) → Secretary of Commerce recommends → President has 90 days to act - Current application: 25% steel tariffs and 10% aluminium tariffs imposed 2018 under Trump's first term; remained in place through Biden years and are intact after 2026 ruling - Legal basis: Congress has explicitly granted tariff authority under this provision, distinguishing it from IEEPA
Section 301 (Trade Act, 1974): - Authority: USTR can investigate "unreasonable or discriminatory" foreign trade practices burdening US commerce; President can respond with tariffs, trade restrictions, or negotiations - Process: USTR investigation (12 months) → findings → Presidential action - Current application: China-specific Section 301 tariffs (imposed 2018–2019, maintained by Biden, expanded by Trump's second term) remain in effect; new investigations launched in 2026 against "most major trading partners" - Distinction from IEEPA: Section 301 requires a USTR investigative finding; IEEPA required only a Presidential emergency declaration
Section 122 (Trade Act, 1974): - Authority: President can impose temporary import surcharges (up to 15%) for up to 150 days to address a "large and serious" balance of payments deficit - New 10% global tariff effective June 24, 2026, imposed under this authority
Section 201 (Trade Act, 1974): - Authority: "Safeguard" tariffs where imports cause serious injury to domestic industry (regardless of unfair trade practices) - Process: USITC investigation → injury determination → Presidential action
Connection to this news: The administration's shift from IEEPA to Section 232 and Section 301 signals a procedurally more constrained but potentially more durable trade policy — each requires investigative findings rather than a bare Presidential declaration.
Major Questions Doctrine — Constitutional Significance
The "major questions doctrine" is a principle of US statutory interpretation that requires courts to find explicit Congressional authorisation before allowing executive agencies or the President to claim authority over matters of vast economic and political significance. It was significantly expanded by the Supreme Court in West Virginia v. EPA (2022), where the Court struck down EPA's authority to mandate economy-wide energy transitions without specific Congressional direction.
- West Virginia v. EPA (2022): landmark application of major questions doctrine; held EPA could not set carbon emission limits that amounted to regulating the entire US energy sector absent explicit Congressional authority
- February 2026 IEEPA ruling: extends major questions doctrine to Presidential tariff powers; Court held tariff-setting — a core congressional power under Article I, Section 8 of the US Constitution — requires explicit delegation
- Indian analogy: India's Parliament similarly retains plenary power over taxation (Article 265 — no tax shall be levied except by authority of law); executive cannot unilaterally impose taxes without legislative authorisation
Connection to this news: The ruling has broad implications — it signals the US Supreme Court's inclination to police executive overreach on economically significant questions, potentially limiting future emergency-powers-based trade actions.
India-US Trade Relations — Implications
India was among the countries targeted by IEEPA tariffs (a 26% "reciprocal" tariff had been imposed). The Supreme Court ruling temporarily removes that specific tariff but new Section 301 investigations against "most major trading partners" — including India — are being initiated.
- India-US bilateral trade (FY 2024-25): approximately USD 130 billion; US is India's largest trading partner
- India's trade surplus with US: approximately USD 35 billion — US has cited this surplus as a key grievance
- Indian exports at risk: pharmaceuticals, IT services, textiles, gems & jewellery, engineering goods
- Generalised System of Preferences (GSP): India lost GSP benefits in June 2019 (Trump's first term); reinstatement has been under discussion but not finalised
- Section 301 investigation process: takes 12 months; gives India time to negotiate and offer concessions (market access, procurement, tariff reductions on US goods) to avoid punitive tariffs
- India's strategic response: India has been pursuing bilateral trade agreement negotiations with the US; recent bilateral meetings have focused on "mini-deal" frameworks to resolve specific trade irritants
Connection to this news: While the Supreme Court's ruling is a short-term reprieve for India on IEEPA tariffs, the pivot to Section 301 investigations creates a medium-term tariff threat that India will need to manage through diplomacy and concession negotiations.
