A Supreme Court ruling on Friday struck down certain tariffs, potentially offering relief to businesses and finance chiefs who have been operating amid prolonged uncertainty.
On Friday morning, the court ruled 6–3 that President Trump cannot impose tariffs under the International Emergency Economic Powers Act (IEEPA), as he did throughout much of 2025. The decision narrows the scope of the president’s unilateral tariff authority and invalidates portions of the levies on steel and aluminum, as well as certain tariffs on imports from China, Fortune reported.
