Supreme Court Rules Most of Donald Trump's Tariffs Are Illegal

In a 6-3 ruling, justices upended the Trump administration's signature economic policy, potentially putting the US government on the hook for at least $175 billion in tariff refunds.

The US Supreme Court on Friday overturned most of President Donald Trump’s tariffs, which could lead to more than $175 billion in tariff refunds for American companies. In a 6-3 decision, the justices ruled that the International Emergency Economic Powers Act (IEEPA)—the law that the Trump administration used to justify many of his sweeping global tariffs—does not grant the president the power of taxation, and tariffs are a form of tax on imports.
