Further pharma uncertainty as Trump’s tariff push faces legal setback

In a major ruling on Friday, the US Supreme Court struck down the bulk of President Donald Trump’s global tariff program, concluding that his administration lacked legal authority under the International Emergency Economic Powers Act (IEEPA) to impose broad import taxes without explicit congressional approval. 

The court’s six-to-three decision reaffirmed that only Congress may levy tariffs unless it clearly delegates that power — and found that IEEPA does not do so.
