The US Supreme Court has ruled most of Donald Trump's tariffs illegal, casting doubt on the Turnberry agreement signed in July 2025. The European Parliament has suspended its implementation pending clarifications from Washington. Trump has threatened higher tariffs if the ruling is exploited.
The Turnberry agreement, negotiated in July 2025 at the Turnberry golf course in Scotland, was secured under the threat of a 30% US surtax on imports. Donald Trump obtained the removal of EU tariffs on American industrial products in exchange for a 15% minimum tariff on most European exports to the United States. Commission President Ursula von der Leyen was summoned there by Trump, who boasted of having signed 'the greatest deal ever'.
Seen as a capitulation for Europe, this transatlantic framework agreement immediately sparked outrage, described as a 'disgrace' and 'humiliation'. Last Friday, the US Supreme Court, in a 6-3 decision, invalidated much of these 'reciprocal' tariffs imposed on the European Union, Canada, Mexico, and other countries.
In response, the European Parliament announced on Monday the suspension of the agreement's implementation, awaiting clarifications from Washington. Trump reacted by the end of the day, warning that any attempt to exploit the judicial decision would result in 'much higher' tariffs. The fate of this deal remains uncertain as Europe considers potential retaliatory measures.
