The fate of President Donald Trump’s sweeping “Liberation Day” tariffs on foreign imports may play out in court, after the first major legal challenge to them was filed in court Monday, as conservative lawyers have alleged the president is exceeding his authority by enacting tariffs under the International Emergency Economic Powers Act (IEEPA).

President Trump’s “Liberation Day” tariffs came under their first major legal challenge Monday, brought by a libertarian public-interest firm that argues the president overstepped his authority. Trump’s April 2 announcement imposed a baseline 10 percent tariff on imports and targeted dozens of countries with higher “reciprocal” tariffs.

California on Wednesday filed a lawsuit seeking to block U.S. President Donald Trump's sweeping tariffs on foreign trading partners, accusing him of abusing his powers and inflicting financial harm on the state and nation.
