In his majority opinion for the 6-3 decision, Chief Justice John Roberts wrote that the Trump administration’s understanding of the IEEPA would “represent a transformative expansion of the President’s authority over tariff policy” that has no precedent.
Last year, Trump’s efforts to reshape global trade upended global markets, pushing Bitcoin as low as $76,300 in April from a post-election high of $106,000 months before. The president has since softened his stance on “reciprocal” tariffs, but he continues to threaten countries with levies to achieve his international goals.
The decision won’t affect all of Trump’s tariffs, but his eagerness to impose levies has stoked geopolitical and economic uncertainties for much of his second term, whether that’s a strain on the U.S. existing trade alliances or the prospect of higher inflation.
In his dissent, Justice Brett Kavanaugh underscored that the decision has no bearing on whether the White House will need to refund billions of dollars in collected tariff revenue. If lower courts determine that the move is proper, “that process is likely to be a ‘mess,’” he added.
