The US trade court on Thursday ruled against Donald Trump’s latest 10% global tariffs, finding across-the-board tariffs were not justified under a 1970s trade law.

The US court of international trade ruled in favor of small businesses that challenged the tariffs, which took effect on 24 February. The ruling was 2-1, with one judge saying it was premature to grant victory to the small business plaintiffs.

In his February order, Trump invoked section 122 of the Trade Act of 1974, which allows for duties for up to 150 days to correct serious “balance of payments deficits” or head off an imminent depreciation of the dollar.

Thursday’s court ruling found the law was not an appropriate step for the kinds of trade deficits that Trump cited in his February order.

Meanwhile, Trump also said on Thursday he would give the European Union until 4 July to implement trade deal commitments before he raises tariffs on EU goods including cars to “much higher levels”.
