The Supreme Court ruled that President Trump exceeded his authority by imposing sweeping global tariffs under the International Emergency Economic Powers Act (IEEPA), a 1977 law meant for addressing foreign threats during national emergencies. Immediately after the ruling, Trump announced and signed a new 10% global tariff on imports from all countries, invoking Section 122 of the Trade Act of 1974 (a rarely/never-used provision allowing temporary tariffs up to 15% for 150 days to address international payments problems or trade imbalances). There are also existing tariffs not affected by this decision, surviving non-IEEPA tariffs such as those under Section 232 (national security) or Section 301 (unfair trade practices).

Read the decision you constitutional scholars, a key quote from Kavanaugh's dissent: "In essence, the Court today concludes that the President checked the wrong statutory box by relying on IEEPA rather than another statute to impose these tariffs." Trump himself praised Kavanaugh's dissent highly after the ruling, calling him a "new hero" and highlighting how it shows viable paths forward. That's exactly what Trump acted on by quickly pivoting to Section 122 of the Trade Act of 1974 for the new 10% global tariff announced hours later.
