Supreme Court strikes down Trump tariffs, rebuking president's signature economic policy

• The Supreme Court's 6-3 decision affirmed the lower court's ruling that the IEEPA law does not grant the President the authority to unilaterally impose, revoke, or adjust tariffs to reorder the global economy.
• The court's analysis focused on specific wording in the IEEPA statute, concluding that the words 'regulate' and 'importation' do not bear the weight of granting broad tariff imposition power.
• The ruling is expected to trigger a significant 'food fight' over how companies that paid an estimated $133 billion in IEEPA-related tariffs (out of $293 billion total tariff revenue in FY25 & FY26) will be reimbursed.
• The President's ability to use tariffs as immediate, unilateral leverage in trade negotiations is diminished, as future tariff actions would likely require lengthier processes or explicit Congressional delegation.

The Supreme Court has ruled against the President's authority to impose global tariffs under the International Emergency Economic Powers Act (IEEPA), affirming a lower court's decision. This limits the President's unilateral power in trade policy and sets the stage for a complex process of reimbursing companies that paid these tariffs, potentially involving billions of dollars.
