The U.S. trade court has ruled against President Donald Trump’s latest 10% global tariffs, finding across-the-board tariffs were not justified under a 1970s trade law, Reuters reports.

The U.S. Court of International Trade ruled in favor of small businesses that challenged the tariffs, which took effect on February 24.

Following a landmark U.S. Supreme Court decision that struck down tariffs imposed under the International Emergency Economic Powers Act, 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.

The 2-1 ruling found the law was not an appropriate step for the kinds of trade deficits that Trump cited in his February order.

A federal circuit appeal of the CIT’s ruling is expected in the coming weeks.
