A U.S. trade court is weighing the legality of President Donald Trump’s proposed 10% global tariff, a policy already facing multiple legal challenges from states and businesses.
At issue is whether Trump can impose the across-the-board tariff under Section 122 of the Trade Act, a rarely used provision that allows temporary import duties but has never been tested at this scale.
Opponents argue the tariff exceeds presidential authority and could disrupt global trade, while government attorneys contend the measure is lawful and necessary to address trade imbalances.
The case follows a February ruling by the U.S. Supreme Court that struck down earlier Trump tariffs imposed under emergency powers, finding the president had overstepped his authority.
During arguments, judges pressed both sides on the limits of executive power.
The outcome could shape future U.S. trade policy and determine whether broad tariffs can be imposed without congressional approval.
