US Supreme Court Reviews Legality of Trump Tariffs Amid Appeals

A federal appeals court ruled 7-4 that President Donald Trump exceeded his authority by imposing broad tariffs using the International Emergency Economic Powers Act (IEEPA), declaring most of his worldwide tariffs illegal under this law. The court emphasized that only Congress has the constitutional power to set tariffs and regulate commerce with foreign nations, not the president. Despite the ruling, the tariffs remain temporarily in place as the Trump administration plans to appeal the decision to the Supreme Court, which is expected to face a significant constitutional challenge concerning separation of powers. Trump's tariffs were a key part of his economic and foreign policy, intended to generate revenue to fund his $4.5 trillion tax cut package and to renegotiate trade deals, though the court's ruling raises uncertainties for global trade partners and the U.S. economy. The administration and Trump himself have strongly denounced the ruling, framing it as detrimental to the country’s economic future, while critics highlight the potential constitutional overreach. This legal battle also reflects broader tensions with institutions like the World Trade Organization, which Trump’s policies have undermined by disregarding its rules and paralyzing its dispute resolution mechanisms.
