The legal confrontation between the Trump administration and the federal judiciary entered a defining new phase when the Supreme Court struck down Trump’s IEEPA-based tariffs — and Trump responded not by standing down but by reaching for a new legal tool and raising tariffs even higher. The escalation raises profound constitutional questions about the limits of presidential power in trade policy and sets the stage for a legal battle that could shape American governance for a generation.
Trump’s new weapon is Section 122 of the Trade Act of 1974 — a dormant provision that permits 15% tariffs for 150 days before requiring congressional involvement. The administration has framed the 150-day window as a period of constructive transition, during which it will develop new and legally robust tariff mechanisms. Critics, however, note that an untested law invoked under emergency-like conditions is precisely the kind of provision that courts have historically scrutinized most closely.
The international community watched the legal drama unfold with growing unease. German Chancellor Merz and French President Macron both spoke out against the tariff hike, with Merz focusing on economic damage and Macron emphasizing democratic principles. Both expressed concern that the US was undermining the stable trade relationships that underpin the global economy.
The UK, having reached what it believed was a settled 10% tariff agreement with Washington, found itself in a newly uncertain position. British trade and business leaders called for clarity and stability, warning that the constant shifts in US trade policy were making long-term planning impossible and driving up costs for businesses and consumers alike.
For the Trump administration, the legal path forward is fraught. The IEEPA tariffs collected over $130 billion, but 90% of that burden fell on American businesses and consumers. Now facing demands for refunds, a legally untested new authority, and a Supreme Court that has already demonstrated its willingness to restrain executive overreach, the administration must navigate a legal landscape that has suddenly become far more hostile. The next 150 days will be decisive.
