Trump administration appeals its latest court loss on tariffs

The Trump administration has filed an appeal against the latest US court ruling that struck down its sweeping global tariffs. Government lawyers argue that the president was acting under national security authority and that the court should defer accordingly.

The case marks a new phase in the tariff fight that has dominated US trade policy this year. Multiple federal courts have reached different conclusions on the legal basis of the executive orders that put the duties in place. Wall Street economists warn that the case's progress could directly affect US exporters, global supply chains and the inflation outlook.

Capitals from Brussels to Tokyo are tracking the proceedings closely. The European Commission, in particular, is wary because any ruling could disturb the ongoing negotiating timetable with Washington. The length of the appeals process may itself reshape the schedule of upcoming trade rounds.
