Supreme Court Agrees to Review Challenges to the IEEPA Tariffs

core/heading

On September 9, the Supreme Court&nbsp;<a href="https://www.supremecourt.gov/orders/courtorders/090925zr1_hejm.pdf">announced</a>&nbsp;that it will hear the Trump Administration’s<a href="https://www.supremecourt.gov/DocketPDF/25/25-250/373615/20250903200201802_Trump_v._VOS_petition-final.pdf">&nbsp;challenge</a>&nbsp;to lower court rulings that the President exceeded his authority in issuing Reciprocal and Trafficking Tariffs under his International Emergency Economic Powers Act (IEPPA) authority.&nbsp;

core/paragraph

The court will determine two questions - Whether IEEPA authorizes the tariffs imposed by the President pursuant to the national emergencies declared, and, if IEEPA authorizes the tariffs, whether the statute unconstitutionally delegates legislative authority to&nbsp;the President.

The Supreme Court has expedited its review with a decision likely before the end of the year. The Administration has until September 19 to file its opening brief in the case, while the initial petitioners, consisting of several states and small businesses, have until October 20 to file their responses.

Interested parties in support of the Administration may file amicus briefs until September 23 and supporters of the petitioners will have until October 24. Oral arguments are scheduled for the first week of November.

The IEEPA tariffs remain in effect during the Supreme Court's review.
