WASHINGTON – The Supreme Court of the United States deals a major blow to President Donald Trump’s trade agenda, overturning global tariffs imposed on dozens of countries, including Nigeria.
In a 6–3 ruling, the court holds that Trump lacks authority under the International Emergency Economic Powers Act to impose sweeping import duties without congressional approval.
Chief Justice John Roberts says the law does not grant the president unilateral power to impose tariffs of unlimited scope.
“The president asserts extraordinary authority,” Roberts writes. “But Congress has not authorised tariffs under IEEPA.”
The case originates from a lawsuit filed by 12 states and five small businesses, who argue the tariffs unlawfully expanded executive power.
The decision curtails a central pillar of Trump’s trade policy and is expected to reshape how future administrations pursue protectionist measures.
Justices Clarence Thomas, Brett Kavanaugh and Samuel Alito dissent, warning that the ruling may constrain executive flexibility during economic disputes. US Supreme Court Strikes Down Trump Tariffs Affecting Nigeria
Trade analysts say the judgment offers relief to affected countries and reinforces legislative oversight over US trade policy.
