President Donald Trump warns of economic ruination if courts rule against his tariffs after the U.S. Court of International Trade blocks emergency import taxes.

FishUSA, a Fairview-based fishing equipment company, joined a lawsuit challenging tariffs imposed under the International Emergency Economic Powers Act. It's too soon to know if a recent ruling by a U.S. appeals court will reduce the size and number of tariffs imposed by the Trump administration.

Federal judges ruled that the president had gone beyond his authority in imposing levies on goods imported from around the world.
