On November 5, the Supreme Court heard oral arguments in the contentious case challenging President Donald Trump’s authority to levy broad tariffs through a series of executive orders enacted in 2025. As is frequently the case with high-stakes litigation, the court’s ruling will be pivotal for U.S. importers burdened with substantial monthly tariff payments. However, the timeline for the decision remains ambiguous.
The Supreme Court operates under informal guidelines and practices, meaning the justices will release their decision when they reach a consensus. Currently, there is no indication the court considers this an emergency necessitating an expedited ruling. Historically, the justices adhere to a predetermined calendar and are not set to return until their “non-argument session” on February 20, suggesting the decision might not come before this date.
The opinion-writing process involves the justices voting on the case and assigning a senior justice in the majority to draft the main opinion. The draft is circulated among the justices, who can join, suggest amendments, or write separate concurring or dissenting opinions. Given the complexity and different perspectives on Trump’s use of the International Emergency Economic Powers Act (IEEPA) for imposing tariffs, the case may generate multiple opinions and thus delay the final decision.
Chief Justice John Roberts and Justice Elena Kagan expressed potential skepticism regarding Trump’s power under IEEPA, pondering whether it breaches the “major questions” doctrine, or if Congress has sole jurisdiction over taxation and foreign trade. In contrast, Justice Samuel Alito showed sympathy toward the broad interpretation of emergency powers under IEEPA.
For those awaiting financial relief from the tariffs, an expedited ruling remains unlikely unless the court diverges from its typical schedule, a move it has reserved for cases with more immediate national impacts. Such was the case with the accelerated timetable for rulings in TikTok v. Garland and Trump v. Anderson, both released without the justices taking the bench.
Importantly, although lower courts have delayed enforcement of their decisions awaiting the Supreme Court’s judgment, the tariffs remain in effect. Should the court deem the tariffs unconstitutional, the question of refunds could complicate matters further, but it might be remanded to lower courts or handled by delaying the ruling’s implementation.
For now, businesses and legal practitioners await the court’s decision, aware that the Supreme Court’s timelines are often impervious to external pressure. For further insights on the anticipated ruling, see the detailed analysis here.
