Supreme Court Ruling Shakes EU-Trade Relations
The recent Supreme Court decision striking down tariffs imposed under the emergency act has created new uncertainties for businesses and policymakers in Brussels. The questions are numerous, and the challenges are equally significant.
European industry associations welcomed the decision, as highlighted by Oliver Richtberg of the VDMA, representing 3,500 European mechanical engineering firms, calling it “an significant signal for rule-based trade and legal certainty.”
Uncertainty Persists Despite Ruling
Despite the ruling, uncertainty remains for European companies. Richtberg cautioned that Trump retains “alternative legal grounds to impose global tariffs.” The practical implications of the decision are still unclear, contributing to ongoing business uncertainty.
Impact on Investment Goods Industry
The mechanical and plant engineering sector, a major employer in both the EU-27 and Germany, relies on dependable export rules to the US. These rules are now once again in question. This has created a sense of unease within the European Commission, responsible for trade agreements.
The situation was initially thought to be resolved, with a complex tariff arrangement carefully balanced, and finalized. The Supreme Court ruling has thrown this into doubt, causing near shock within the Commission, as a deal with Trump now appears less secure.
What Comes Next?
Companies on both sides of the Atlantic need stability and predictability in trade relations, according to a European Commission spokesperson. The mood in Brussels is ambivalent: relief that a US court acknowledged concerns shared in Brussels, coupled with the question of what happens now.
Bernd Lange, chair of the Trade Committee in the European Parliament, described the situation as “a slap in the face for Trump’s arbitrary one-man show tariff policy.”
The Trade Committee had planned to approve the implementation of the EU-US trade agreement next week. The now-illegal “global tariffs” were part of the “Turnberry Deal,” negotiated in July 2025 at the Trump Turnberry Resort in Scotland. Green EU trade policy representative Anna Cavazzini stated to ARD-Hörfunk that the agreement cannot be approved in the current climate.
More at Stake Than Just Tariffs
The implications extend beyond the tariffs themselves. The EU had committed to purchasing $750 billion worth of US energy by 2028, $600 billion in new US investments, and procuring US military equipment. Questions likewise arise regarding the abolition of tariffs on all US industrial goods into Europe, while the US maintained a 15% base tariff on most European exports. Expanded US access to the EU market for agricultural products, such as lobster and meat, is also in question.
Meeting on Monday to Clarify EU Approach
Whether the vote will proceed as scheduled next Tuesday is uncertain. The ratification process could be “suspended or adjusted,” according to members of the Trade Committee. A meeting is scheduled for Monday to determine the next steps. Few expect the agreement to proceed as planned.
The immediate concern is what happens to the tariffs. And what measures will the EU accept if Trump retaliates with additional tariffs based on less contestable legal grounds? Who will pay compensation, and who will provide refunds?
consumers, businesses, and markets face new uncertainties in transatlantic trade relations.
Tariffs Beyond the Emergency Act Also Burden EU
The Supreme Court ruling did not address tariffs imposed on more solid legal grounds. These tariffs, including those on steel, aluminum, and automobiles, continue to burden the EU.
The US court did not set a deadline for implementing the ruling. How and how quickly the government must remove the tariffs remains unresolved, as do the practical implications – how tariffs are adjusted, settled, or overpaid amounts refunded. Further legal disputes are likely.
For the European Commission and Brussels trade policymakers, one thing is certain: consumers, businesses, and markets face new uncertainties in transatlantic trade relations.
