The US Supreme Court has dealt a significant blow to former President Donald Trump by rejecting tariffs he imposed under the International Emergency Economic Powers Act (IEEPA). In a 6-3 ruling, the court determined that Trump exceeded his authority by using the IEEPA, which is designed for national emergencies but had never been applied to impose tariffs before. This ruling marks a historic decision as Trump was the first US president to employ this act for tariff imposition, raising questions about executive power in economic matters.

The tariffs were originally introduced in April of the previous year, on 'Libération Day', affecting nearly every country worldwide with rates as high as 50%. The Supreme Court's decision addressed the legality of these tariffs, which had been a point of contention both domestically and internationally. Legal experts indicate that this ruling may have far-reaching implications for US foreign trade policy and the limits of presidential authority regarding economic sanctions and tariffs.

Furthermore, the court's decision could influence ongoing trade negotiations between the US and other countries, including India, as questions arise about the legitimacy of tariffs imposed under emergency circumstances. As the legal landscape changes, it remains to be seen how this ruling will affect existing tariffs and future trade agreements. The outcome highlights the delicate balance of power between the executive branch and the judiciary in matters of economic governance.
