Trump says Justices Barrett, Gorsuch ‘sicken me’ after Supreme Court tariff ruling

The Supreme Court ruled that President Trump did not have authority under the International Emergency Economic Powers Act (IEEPA) to unilaterally impose tariffs. The decision removes a legal foundation for executive-imposed tariffs, constraining future administrations' ability to enact broad trade barriers without congressional authorization and increasing policy predictability. Expect implications for sectors exposed to tariff risk (metals, industrials, import-sensitive manufacturers) as the ruling reduces the near-term likelihood of ad hoc tariff actions, though Congress or other statutory tools could remain avenues for targeted measures.
