The U.S. Supreme Court has delivered a landmark 6‑3 decision striking down most of former President Donald Trump’s sweeping global tariffs, saying the law he used to enforce them does not give the president authority to impose such import taxes without clear Congressional approval.
The ruling, based on the International Emergency Economic Powers Act (IEEPA), means that many tariffs imposed under that statute — which collectively generated billions in revenue — are now deemed unlawful. Tariffs collected under IEEPA may need to be refunded, with estimates suggesting more than $175 billion in tariff revenue could be affected.
In response, some major U.S. companies, including FedEx, have already filed lawsuits seeking refunds for duties they paid under the now‑invalidated tariffs.
Republican leaders have said the administration may pursue other legal avenues to impose duties, while some lawmakers are pushing legislation to ensure full refunds reach affected businesses.
Economists warn the decision could have wide implications for the U.S. economy, global trade relationships, and consumer prices, especially if alternative tariffs are introduced under different authorities
