The long wait is over. The United States Supreme Court has ruled that tariffs imposed during the presidency of donald trump under the International Emergency Economic Powers Act (IEEPA) are illegal. A decision that unblocks dozens of lawsuits and opens the door to a complex process of possible multimillion-dollar reimbursements.
The ruling, issued last Friday, February 20, 2026, was resolved by 6 votes in favor and 3 against, in an opinion signed by the president of the court, John Roberts. In it, the Court concludes that the IEEPA does not grant the president a general power to impose tariffs in peacetime, a distinction that appears repeatedly in the text between war situations and ordinary scenarios.
Trump’s tariffs are illegal
This resolution directly affects the cases that had been frozen in the United States International Trade Court, awaiting a definitive interpretation from the high court. Among them is the lawsuit filed by Kawasakione of the first manufacturers to question the legality of the tariffs, but not the only one.
Large companies from very different sectors, such as costco, YETI Coolers, Goodyear either GoProjoined a wave of resources with the same objective: to cancel the taxes and recover the money already paid for imports subject to those rates. That is, “American trillions” of dollars.
The judge’s concurring opinion Neil Gorsuch underlines one of the pillars of the ruling: the Constitution attributes to Congress, and not the president, the power to impose tariffs. According to Gorsuchaccepting the interpretation defended by the Executive would have meant granting any president practically unlimited power to tax imports, alleging emergencies defined by himself and without effective control.
Along the same lines, the judge Elena Kagan affects the very language of the IEEPA. The law lists dozens of possible actions against foreign threats (from blocking to prohibiting transactions), but none of them contemplate raising revenue through tariffs. For kaganthe text is clear: regulating is not equivalent to imposing taxes. The judge Ketanji Brown Jackson He added that the role of the courts is not to legislate, but to apply the will expressed by Congress when it is explicitly reflected in a norm.
In the dissident bloc, the judge Brett Kavanaugh He defended that Congress has historically authorized the president to impose tariffs, although his vote introduces a significant nuance: the problem, in his opinion, would not be so much the existence of the tariffs as the law used to justify them. In his opinion, other federal regulations could have served as a legal basis if proper procedures had been followed, a statement that has attracted attention for seeming to be an implicit guide for future actions of the Executive.
With the Supreme Court’s decision now published, the International Trade Court will be able to resume the suspended proceedings and begin to determine how and when plaintiff companies will be able to request refunds. The ruling itself anticipates that the process will be complex, given the volume of money collected during years of application of these tariffs.
Effects of this decision on the 2-wheel industry
The Supreme Court’s decision will have direct and indirect effects on the motorcycle industry, especially for those who manufacture, import or assemble motorcycles in the United States or depend on foreign parts and components. First, the tariffs that had been applied under the IEEPA raised the costs of importing complete motorcycles and parts, which made the final products more expensive or reduced the margins of manufacturers and distributors.
With the cancellation of these levies, these additional charges no longer apply and companies could recover part of the costs paid, which would alleviate pressures on prices and profit margins and, potentially, allow a reduction in prices for the consumer.
Additionally, the elimination of these tariffs reduces uncertainty in already tight global supply chains, benefiting brands such as Kawasaki and other importers who had pursued similar litigation to recover payments and stabilize their operations in a complex international trade context.
Still, it remains to be seen how refunds will be formally managed and what new tariff measures could be applied under other laws, which maintains some uncertainty for long-term planning within the sector.
Meanwhile, Washington has already expressed its disagreement with the ruling and has made it clear that it will explore other legal avenues to reinstate tariff measures. That is, other types of liens. Of course, the judicial battle has ended on this front, but the political and economic debate on the use of tariffs as a pressure tool is far from closed.
