WASHINGTON, May 30, 2025 (BSS/AFP) - US President Donald Trump on Thursday celebrated a temporary reprieve for his aggressive tariff strategy, with an appeals court preserving his sweeping import duties on China and other trading partners -- for now.

The short-term relief will allow the appeals process to proceed, after the US Court of International Trade on Wednesday barred most of the tariffs announced since Trump took office, ruling that he had overstepped his authority.

Welcoming the latest twist in his legal skirmishes over his trade policies, Trump lashed out at the Manhattan-based trade court, saying its blockade should be "quickly and decisively" reversed for good.

"Backroom 'hustlers' must not be allowed to destroy our Nation!" Trump said in a long rant on his Truth Social platform in which he again painted himself as a target of a biased judicial system.

Since returning to the presidency in January, Trump has moved to reconfigure US trade ties with the world while using levies to force foreign governments to the negotiating table.

But the stop-start tariff rollout, impacting both allies and adversaries, has roiled markets and snarled supply chains.

Prior to Thursday's decision from the US Court of Appeals for the Federal Circuit, known as an administrative stay, the White House was given 10 days to halt affected tariffs.

The Trump administration called the ruling "blatantly wrong," expressing confidence that the decision would be overturned on appeal.

White House spokeswoman Karoline Leavitt told reporters that the judges "brazenly abused their judicial power to usurp the authority of President Trump."

Leavitt said the Supreme Court "must put an end" to the tariff challenge, while stressing that Trump had other legal means to impose levies.

A separate ruling by a federal district judge in the US capital found some Trump levies unlawful as well, giving the administration 14 days to appeal.
