‘Trump will no longer be able to honor many of the “deals” he has negotiated’: How the Supreme Court crippled America’s negotiator-in-chief | Fortune

The Supreme Court just blocked the president from using emergency powers to unilaterally reshape global trade, severing a core lever of executive bargaining without Congress’s explicit authorization.

Summary

The Supreme Court issued a 6–3 decision declaring President Trump’s use of the International Emergency Economic Powers Act to impose broad reciprocal and targeted tariffs unlawful. The ruling narrows presidential control over global commerce by rejecting emergency-power tariff making as a unilateral executive tool. The immediate consequence is a collapse of key negotiating leverage and a looming wave of importer refund demands potentially approaching $120 billion.

Reality Check

When a president uses emergency powers to tax the entire country’s imports as a bargaining chip, we are one step away from executive-made economic law that bypasses the people’s representatives and hits our wallets without durable legal authority. The conduct described is not framed as a clear criminal scheme on these facts, but it squarely implicates unlawful executive action under the International Emergency Economic Powers Act and the constitutional requirement that Congress control tariffs and revenue through statute. The lasting precedent risk is institutional: once emergency authorities are normalized as a tariff-writing shortcut, the next administration can impose sweeping economic penalties first and litigate later, leaving businesses and citizens trapped in retroactive chaos like the refund “mess” now foreseen.

Detail

<p>The Supreme Court ruled 6–3 that the administration’s tariff program imposed under the International Emergency Economic Powers Act (IEEPA) was unlawful. The administration had relied on the IEEPA to apply reciprocal tariffs to most trading partners based on a claimed “balance of payments emergency,” and to impose targeted tariffs on Canada, China, and Mexico based on a claimed “drug trafficking emergency.”</p><p>After the April 2025 “Liberation Day” rollout, the U.S. Treasury collected $240 billion in customs-duty revenue, described as $180 billion more than the same period in 2024; an estimate attributed nine percentage points of a rise in the effective tariff rate to the IEEPA tariffs now struck down. With the tariffs invalidated, importers are expected to seek refunds that estimates place at roughly $120 billion (about 0.5% of GDP). A dissent by Justice Brett Kavanaugh noted the Court did not specify whether or how refunds should be returned and described the process as likely to be a “mess.”</p><p>Legal alternatives discussed include Section 122 of the 1974 Trade Act (15% cap, 150-day limit without congressional approval, nondiscriminatory), and other statutes requiring investigations before tariffs can be imposed.</p>
