The Trump administration requested the Supreme Court to expedite its review by determining whether to hear the case by September 10 and scheduling arguments for November.
The Trump administration has requested that the US Supreme Court on Wednesday, 3 September 2025, to swiftly review the case regarding the President’s use of the International Emergency Economic Powers Act (IEEPA) to impose tariffs.
This follows the announcement by US President Donald Trump will seek an expedited Supreme Court ruling on tariffs deemed illegal by a US Appeals Court.
Earlier, the US Appeals Court ruling on 29 August stated that most of the tariffs imposed by the Trump administration are illegal, but allowed them to remain in place until 14 October to give the administration time to appeal to the Supreme Court.
Tariffs have been a cornerstone of the Trump administration’s foreign policy, used to pressure trading partners and renegotiate trade deals, though they have also caused financial market volatility. The ruling affects Trump’s so-called “reciprocal” tariffs, which are applied to most countries globally, as well as additional tariffs imposed on China, Mexico, and Canada.
The Trump administration seeks a decision by 10 September and arguments in November. Historically, IEEPA has been used for sanctions and asset freezes, not tariffs, making Trump’s use of the law unprecedented.
