Twelve states, led by New York and Arizona, have filed a lawsuit in the U.S. Court of International Trade, challenging President Trump’s tariff policies. They argue that these tariffs, imposed without Congressional approval under the International Emergency Economic Powers Act, undermine constitutional authority and have led to inflation and job losses. State officials described the situation as economically reckless and called for a halt to the enforcement of these tariffs. This lawsuit follows California’s similar legal action last week, and both seek to prevent the tariffs from being enforced due to their perceived illegality.
