The US Supreme Court invalidated President Donald Trump’s broad tariffs implemented under a law designated for national emergencies, marking a significant ruling with global economic repercussions issued on Friday.
In a 6-3 decision led by conservative Chief Justice John Roberts, the justices upheld a lower court’s ruling that Trump overstepped his authority by utilizing the 1977 International Emergency Economic Powers Act (IEEPA).
The court determined that the Trump administration’s interpretation of the IEEPA, granting the president unilateral power to impose tariffs, would encroach on Congress’s powers and violate the “major questions” doctrine, a legal principle demanding clear congressional authorization for significant executive actions.
Roberts, referencing a prior Supreme Court ruling, emphasized that the president must have explicit congressional approval to justify imposing tariffs and concluded that Trump lacked such authorization.
Trump’s strategic use of tariffs as a tool for economic and foreign policy has been a cornerstone of his administration, sparking a global trade conflict that has strained relationships with trading partners, impacted financial markets, and introduced economic uncertainty on a global scale.
The Supreme Court’s decision stemmed from legal challenges brought by affected businesses and 12 states against Trump’s unprecedented application of the IEEPA to unilaterally levy import taxes.
The dissenting justices were conservatives Clarence Thomas, Samuel Alito, and Brett Kavanaugh, while the majority included Roberts, conservative Justices Neil Gorsuch and Amy Coney Barrett, and the three liberal justices.
Trump’s tariffs were anticipated to generate trillions of dollars in revenue for the US over the next decade, with estimates suggesting that the tariffs collected under the IEEPA exceeded $175 billion.
While the US Constitution grants Congress the authority to levy taxes and tariffs, Trump circumvented this by invoking the IEEPA to impose tariffs without congressional approval, a move challenged in the Supreme Court.
The administration vowed to explore alternative legal justifications to maintain Trump’s tariffs, including provisions for national security threats and retaliatory actions against unfair trade practices by US trading partners.
Trump’s use of tariffs as leverage in diplomatic negotiations has elicited mixed responses, with some countries offering concessions to avoid tariffs, while others viewed them as detrimental to international relations.
Historically, the IEEPA has been utilized for imposing sanctions rather than tariffs, with the law not explicitly mentioning tariffs. The Congressional Budget Office estimates that maintaining current tariffs, including those under the IEEPA, could generate around $300 billion annually.
Trump’s imposition of tariffs under the IEEPA has been part of his broader approach to reshape trade relationships and address what he perceived as national emergencies, utilizing tariffs as a bargaining chip in various geopolitical disputes.
The cases presented before the Supreme Court involved multiple lawsuits challenging Trump’s tariff implementation, with rulings favoring businesses, states, and a family-owned toy company contesting the tariffs.
