President Donald Trump on Friday blasted the Supreme Court’s ruling curbing his tariff authority and announced he was imposing a new 10% global tariff beginning today, while keeping existing national security and China-era trade tariffs in place.
On February 20, 2026, the U.S. Supreme Court delivered a 6–3 ruling that struck down a major component of President Donald Trump’s tariff policy, holding that his use of emergency powers to impose sweeping import duties exceeded the legal authority granted under federal law. The decision represents a significant setback for Trump’s economic agenda and has sparked a fierce response from the president.
High Court Rebukes Trump’s Emergency Tariffs
In a consolidated decision, the Supreme Court majority concluded that the 1977 International Emergency Economic Powers Act (IEEPA) — the statute Trump invoked to justify tariffs targeting most foreign trading partners — does not authorize the president to impose broad tariffs. The justices ruled that because the Constitution explicitly grants Congress, not the executive branch, the power to impose taxes and duties, the use of IEEPA for tariffs was unlawful.
The decision aligns with a long‑standing constitutional principle: tariffs and duties are a form of taxation firmly within the legislative branch’s power. Members of the Court’s liberal and moderate wings agreed that IEEPA lacked clear authorization for such economic action, while also rejecting the administration’s claims that the emergency statute could justify broad-based tariff authority.
The ruling affirms lower court judgments that had already blocked the challenged tariffs, which had been imposed after Trump declared national emergencies related to trade deficits and narcotics trafficking.
Dissent and Legal Arguments
The three dissenting justices — Justices Brett Kavanaugh, Clarence Thomas, and Samuel Alito — argued that statutory text, history, and precedent support the president’s authority under IEEPA to regulate imports, including imposing tariffs. In a separate dissent, Justice Kavanaugh emphasized that similar emergency powers had historically been interpreted to permit tariffs, and stressed that Congress could still authorize tariff authority to the executive branch in clear terms.
Despite the dissent, the majority’s interpretation prevailed, drawing a clear line between regulatory authority and the distinct taxing power reserved for Congress.
Trump Condemns Ruling, Announces New Tariff Plan
Following the decision, President Trump unleashed a forceful rebuke of the Supreme Court. Calling the ruling “deeply disappointing,” he criticized the justices and announced that he would immediately impose a new 10% global tariff under a different statutory authority — specifically again citing other trade laws such as the Trade Act of 1974 — to maintain his broader trade agenda.
Trump defended tariffs as central to economic security and credited them with supporting U.S. markets and addressing drug trafficking. He also maintained that many existing tariffs — including those based on national security and unfair trade practices — would remain in place despite the court’s rejection of IEEPA‑based measures.
The former president also sought to cast the decision as a broader affirmation of executive trade authority, pointing to dissenting opinions and suggesting the ruling could clarify presidential power under alternative statutes.
Implications for Policy and Markets
Supreme Court Tariff Ruling Signals Limits on Executive Authority
The Supreme Court’s 6–3 ruling against the broad tariffs imposed under emergency powers marks a significant statement on the separation of powers. By affirming that Congress holds the authority to levy taxes and duties, the decision reinforces the principle that executive actions must operate within clearly defined legal limits.
-
Executive Oversight Strengthened – Presidents must now work within statutory authority, preventing unilateral economic measures that could destabilize markets or trade relationships.
-
Legal Certainty for Businesses – Companies impacted by previously imposed tariffs gain clarity on which measures are lawful, reducing uncertainty in investment and international trade planning.
-
Encouragement of Legislative Involvement – The ruling shifts responsibility back to Congress, emphasizing debate and accountability when shaping national economic and trade policies.
-
Checks on Emergency Powers – Declaring a national emergency can no longer be used as a broad tool for imposing sweeping economic measures, ensuring emergency powers are reserved for genuine crises.
-
Market Stability and Predictability – By limiting unilateral tariffs, the ruling supports consistent trade policies and helps maintain a predictable environment for domestic and international commerce.
The Supreme Court’s decision reinforces that long-term economic stability depends on clearly defined lawmaking and limits on executive discretion, offering a roadmap for future administrations on balancing national security, trade, and economic policy.
Overall Takeaway:
The Supreme Court’s ruling clarifies the limits of executive power in imposing tariffs, reaffirming that major economic decisions require clear legislative authorization. While it curtails broad unilateral measures, the decision ensures greater legal certainty for businesses and underscores the principle of accountability in government. As policymakers and leaders navigate trade and economic strategy, the ruling highlights the importance of balancing national interests with adherence to the rule of law, market stability, and long-term economic growth.
