Storyline: Several U.S. small businesses filed a lawsuit against the government in the U.S. Court of International Trade on Monday, arguing that the presidential administration lacks the authority to impose broad tariffs without congressional approval. The litigation was initiated by the Liberty Justice Center, a non-profit, non-partisan litigation organization, on behalf of five small U.S. firms, according to reports. They are seeking to block the government's tariff measures under the International Emergency Economic Powers Act (IEEPA). The center contends that the U.S. trade deficit, which has existed for decades, does not constitute an emergency or an unusual threat. Moreover, it asserts that IEEPA does not authorize the president to implement comprehensive tariff measures, and there is no provision in the act that grants the power to levy tariffs at all. The businesses involved in the lawsuit claim to have suffered severe damage from the additional tariffs. One of the companies stated that it has already paid an extra 25,000 U.S. dollars in tariffs for imported goods this year, and is projected to face 1.2 million U.S. dollars in tariff costs in 2026, making it difficult for the business to survive. On April 2, U.S. President Donald Trump signed an executive order invoking IEEPA to impose so-called reciprocal tariffs on global trading partners, a move that has sparked strong discontent both domestically and internationally, as well as causing significant turmoil in financial markets.
