Democratic lawmakers celebrated the decision as a check on executive overreach, while Trump called it a "disgrace" and indicated he had a backup plan.
• Supreme Court rules Trump tariffs unconstitutional in 6-3 decision — The US Supreme Court ruled 6-3 last Friday that President Trump exceeded his constitutional authority by imposing tariffs using the International Emergency Economic Powers Act (IEEPA) during peacetime. The court affirmed that Congress alone retains the power to levy taxes under the Constitution and that the IEEPA cannot supersede that authority absent genuine emergency conditions. The ruling marked the first time the Supreme Court overturned Trump policies in his second term and undercut his claims to sweeping executive trade authority.
• Supreme Court rules Trump's tariffs unlawful, striking down invocation of International Emergency Economic Powers Act — The U.S. Supreme Court ruled 6–3 that President Trump lacked authority to impose sweeping global tariffs under the International Emergency Economic Powers Act (IEEPA).

The court held that taxation powers are reserved exclusively to Congress. Trump responded with a vitriolic public attack on the justices, calling them "FOOLS" and "LAPDOGS," and immediately announced new tariffs under different legislative authority.
• Supreme Court strikes down Trump's national emergency tariffs — The U.S. Supreme Court issued a 6-3 decision invalidating Trump's tariffs imposed under the International Emergency Economic Powers Act (IEEPA), ruling that tariffs constitute taxation and fall under Congress's exclusive constitutional authority. The decision reduces the U.S. average trade-weighted tariff from 15.3% to 8.3%, with significant reductions on Chinese (36.8% to 21.2%), Brazilian (26.3% to 6.8%), and Japanese (14.9% to 9.9%) imports. Trump immediately announced a 10% blanket global tariff under Section 122 of the 1974 Trade Act as an alternative.

The White House indicated it will replace the levies using alternative statutory tools, such as the 1974 Trade Act.

The court held that tariff authority belongs exclusively to Congress under the Constitution's taxing power. Trump responded by calling the justices "a disgrace to the nation" and immediately announced a new 10% global baseline tariff under Section 122 of the Trade Act of 1974, which permits 150-day tariffs, while initiating investigations into unfair trading practices for potential permanent tariffs.
• US Supreme Court strikes down Trump's unilateral tariff authority under IEEPA — The US Supreme Court ruled 6–3 that President Trump exceeded his constitutional authority by imposing global tariffs without congressional approval under the International Emergency Economic Powers Act (IEEPA).

Trump immediately vowed to continue tariffs using alternative authority under the Trade Act of 1974, announcing a new 10% global tariff and directing investigations into unfair trading practices.

• Trump claims he has unchecked power after Supreme Court ruling — Trump publicly stated that the Supreme Court's ruling has given him "far more powers and strength" than before, suggesting he could use tariffs in a more aggressive manner.

• US Supreme Court schedules oral arguments on Trump tariff legality — The US Supreme Court announced it will hear oral arguments on November 5, 2025, regarding the legality of President Trump's sweeping global tariffs imposed under the International Emergency Economic Powers Act (IEEPA). A federal appeals court had ruled in August that Trump overstepped his authority by using a law meant for emergencies to impose broad tariffs without congressional approval. The case was placed on a fast track. A Supreme Court defeat could halve the current average US effective tariff rate and force repayment of tens of billions in collected tariffs.
