A federal court has ruled that President Trump’s “Liberation Day” tariffs exceeded presidential authority under the International Emergency Economic Powers Act (IEEPA), marking a significant check on executive power in trade policy.
🧾 Overview: Court Invalidates Trump’s Tariffs
On May 28, 2025, the U.S. Court of International Trade (CIT) unanimously ruled that President Donald Trump’s “Liberation Day” tariffs were unconstitutional. The court found that the tariffs, imposed under the International Emergency Economic Powers Act (IEEPA), exceeded the authority granted to the executive branch, as they were not justified by a legitimate national emergency.
⚖️ Legal Basis: IEEPA and Executive Authority
The Trump administration had invoked the IEEPA to justify the tariffs, citing trade deficits as a national emergency. However, the court determined that trade deficits do not constitute an “unusual and extraordinary threat” as required by the IEEPA. The decision emphasized that the power to impose tariffs lies with Congress, and the executive branch cannot unilaterally impose such measures without clear legislative authorization. Wikipedia

U.S. stock indexes rose, and the dollar strengthened, as investors viewed the ruling as a check on executive overreach in trade policy. The decision alleviated concerns about market instability due to unilateral tariff implementations.

The ruling has significant implications for U.S. trade relations. Countries affected by the tariffs, such as China, Canada, Mexico, and Australia, welcomed the decision. Australian Trade Minister Don Farrell expressed hopes that the ruling would help remove tariffs harming both the U.S. and Australian economies.
