The US Appeals Court ruled that the majority of Trump-era tariffs are unlawful, but they will remain in effect until 14 October while a potential Supreme Court review is considered.
US President Donald Trump announced plans to seek an expedited Supreme Court ruling on tariffs deemed illegal by a US Appeals Court.
The US Appeals Court ruled, on 29 August 2025, that most of the tariffs imposed by the Trump administration are illegal, but allowed them to remain in place until 14 October to give the administration time to appeal to the Supreme Court.
The ruling affects Trump’s so-called “reciprocal” tariffs, which are applied to most countries globally, as well as additional tariffs imposed on China, Mexico, and Canada.
Trump emphasised the importance of the decision, warning of potential economic harm if the ruling goes against his policy.
“It’s a very important decision, and frankly, if they make the wrong decision, it will be devastation for our country,” Trump said.
Treasury Secretary Scott Bessent expressed confidence that the Supreme Court would uphold Trump’s use of a 1977 emergency powers law to impose the tariffs.
Despite the US appeals court ruling, USTR (United States Trade Representative) is continuing trade talks with other countries, according to US Trade Representative Jamieson Greer.
